A prospective study of posttraumatic stress disorder symptoms and coronary heart disease in women.

Objective: Posttraumatic stress disorder (PTSD) reflects a prolonged stress reaction and dysregulation of the stress response system and is hypothesized to increase risk of developing coronary heart disease (CHD). No study has tested this hypothesis in women even though PTSD is more prevalent among women than men. This study aims to examine whether higher levels of PTSD symptoms are associated with increased risk of incident CHD among women. Design: A prospective study using data from women participating in the Baltimore cohort of the Epidemiologic Catchment Area study (n = 1059). Past year trauma and associated PTSD symptoms were assessed using the NIMH Diagnostic Interview Schedule. Main Outcome Measures: Incident CHD occurring during the 14-year follow-up through 1996. Results: Women with five or more symptoms were at over three times the risk of incident CHD compared with those with no symptoms (age-adjusted OR = 3.21, 95% CI: 1.29-7.98). Findings were maintained after controlling for standard coronary risk factors as well as depression or trait anxiety. Conclusion: PTSD symptoms may have damaging effects on physical health for civilian community-dwelling women, with high levels of PTSD symptoms associated with increased risk of CHD-related morbidity and mortality.

Contribution of job control and other risk factors to social variations in coronary heart disease incidence

BACKGROUND: The first Whitehall Study showed an inverse social gradient in mortality from coronary heart disease (CHD) among British civil servants--namely, that there were higher rates in men of lower employment grade. About a quarter of this gradient could be attributed to coronary risk factors. We analysed 5-year CHD incidence rates from the Whitehall II study to assess the contribution to the social gradient of psychosocial work environment, social support, coronary risk factors, and physical height. METHODS: Data were collected in the first three phases of examination of men and women in the Whitehall II study. 7372 people were contacted on all three occasions. Mean length of follow-up was 5.3 years. Characteristics from the baseline, phase 1, questionnaire, and examination were related to newly reported CHD in people without CHD at baseline. Three self-reported CHD outcomes were examined: angina and chest pain from the Rose questionnaire, and doctor-diagnosed ischaemia. The contribution of different factors to the socioeconomic differences in incident CHD was assessed by adjustment of odds ratios. FINDINGS: Compared with men in the highest grade (administrators), men in the lowest grade (clerical and office-support staff) had an age-adjusted odds ratio of developing any new CHD of 1.50. The largest difference was for doctor-diagnosed ischaemia (odds ratio for the lowest compared with the highest grade 2.27). For women, the odds ratio in the lowest grade was 1.47 for any CHD. Of factors examined, the largest contribution to the socioeconomic gradient in CHD frequency was from low control at work. Height and standard coronary risk factors made smaller contributions. Adjustment for all these factors reduced the odds ratios for newly reported CHD in the lowest grade from 1.5 to 0.95 in men, and from 1.47 to 1.07 in women. INTERPRETATION: Much of the inverse social gradient in CHD incidence can be attributed to differences in psychosocial work environment. Additional contributions were made by coronary risk factors--mainly smoking--and from factors that act early in life, as represented by physical height.     

Association of coronary heart disease incidence with carotid arterial wall thickness and major risk factors: the Atherosclerosis Risk in Communities (ARIC) Study, 1987-1993

Few studies have determined whether greater carotid artery intima-media thickness (IMT) in asymptomatic individuals is associated prospectively with increased risk of coronary heart disease (CHD). In the Atherosclerosis Risk in Communities Study, carotid IMT, an index of generalized atherosclerosis, was defined as the mean of IMT measurements at six sites of the carotid arteries using B-mode ultrasound. The authors assessed its relation to CHD incidence over 4-7 years of follow-up (1987-1993) in four US communities (Forsyth County, North Carolina; Jackson, Mississippi; Minneapolis, Minnesota; and Washington County, Maryland) from samples of 7,289 women and 5,552 men aged 45-64 years who were free of clinical CHD at baseline. There were 96 incident events for women and 194 for men. In sex-specific Cox proportional hazards models adjusted only for age, race, and center, the hazard rate ratio comparing extreme mean IMT (> or = 1 mm) to not extreme (< 1 mm) was 5.07 for women (95% confidence interval 3.08-8.36) and 1.85 for men (95% confidence interval 1.28-2.69). The relation was graded (monotonic), and models with cubic splines indicated significant nonlinearity. The strength of the association was reduced by including major CHD risk factors, but remained elevated at higher IMT. Up to 1 mm mean IMT, women had lower adjusted annual event rates than did men, but above 1 mm their event rate was closer to that of men. Thus, mean carotid IMT is a noninvasive predictor of future CHD incidence.     

Relationship of job strain to standard coronary risk factors and psychological characteristics in women and men of the Family Heart Study.

This study reports on standard coronary risk factors (plasma lipids and lipoproteins, blood pressure, heart rate, age, body mass index) and psychosocial variables (job strain, Type A behavior, hostility, illnesses, medical and psychological symptoms, health-damaging behavior) in a community sample of 324 employed men, 203 employed women, and 155 female homemakers. Employed women reported less hostility and fewer illnesses than homemakers and had lower cholesterol levels than homemakers and men. Job characteristics were unrelated to standard coronary risk factor levels in both sexes, but predicted medical symptoms and health-damaging behavior in men. These findings suggest that employment is associated with enhanced medical and physical well-being among women and point to possible behavioral and psychological pathways by which job strain may adversely influence men's health.

Impact of major cardiovascular disease risk factors, particularly in combination, on 22-year mortality in women and men

BACKGROUND: The appropriateness of current cardiovascular disease (CVD) risk factor guidelines in women continues to be debated. OBJECTIVE: To present new data on the appropriateness of current CVD risk factor guidelines, for women and men, from long-term follow-up of a large population sample. METHODS: Cardiovascular disease risk factor status according to current clinical guidelines and long-term impact on mortality were determined in 8686 women and 10503 men aged 40 to 64 years at baseline from the Chicago Heart Association Detection Project in Industry; average follow-up was 22 years. RESULTS: At baseline, only 6.6% of women and 4.8% of men had desirable levels for all 3 major risk factors (cholesterol level, <5.20 mmol/L [<200 mg/dL]; systolic and diastolic blood pressure, <120 and <80 mm Hg, respectively; and nonsmoking). With control for age, race, and other risk factors, each major risk factor considered separately was associated with increased risk of death for women and men. In analyses of combinations of major risk factors, risk increased with number of risk factors. Relative risks (RRs) associated with any 2 or all 3 risk factors were similar: for coronary heart disease mortality in women, RR= 5.72 (95% confidence interval [CI], 2.35-13.93), and in men, RR = 5.51 (95% CI, 3.10-9.77); for CVD mortality in women, RR = 4.54 (95% CI, 2.33-8.84), and in men, RR = 4.12 (95% CI, 2.56-6.37); and for all-cause mortality in women, RR = 2.34 (95% CI, 1.73-3.15), and in men, RR = 3.20 (95% CI, 2.47-4.14). Absolute excess risks were high in women and men with any 2 or all 3 major risk factors. CONCLUSIONS: Combinations of major CVD risk factors place women and men at high relative, absolute, and absolute excess risk of coronary heart disease, CVD, and all-cause mortality. These findings support the value of (1) measurement of major CVD risk factors, especially in combination, for assessing long-term mortality risk and (2) current advice to match treatment intensity to the level of CVD risk in both women and men.     

The role of Ly49A and 5E6(Ly49C) molecules in hybrid resistance mediated by murine natural killer cells against normal T cell blasts

Due to affluence and a sedentary life style a great deal of people in the western countries are affected by coronary heart disease (CHD). The relation between CHD and certain risk factors pertaining to life style is evaluated in this study. A primary purpose is to study certain crucial risk factors for women. The main variables are age, smoking, overweight (measured by BMI), blood pressure and exercise. This prospective study is based on self-reported data from the nation-wide Swedish Level of Living Survey and on data from the national Cause of Death Register. The data were analysed separately by sex using a proportional hazards model. The sample was divided into two strata: those with heart disease and/or diabetes initially, and all the rest. A sample of 2546 men and 2760 women between 45 and 74 years of age was followed from 1980 to the end of 1990. During this period 189 men and 75 women died of coronary heart disease (CHD). It was found that high blood pressure raised the relative risk (RR) of death from CHD by almost 60% in both men and women. Male smokers (> 14 cigarettes a day) had about 60% (significant) and female smokers (> 10 cigarettes a day) 150% (significant) excessive mortality from CHD. Different levels of overweight among women were strongly related to excess mortality from CHD, ranging between 100 and 300%. Among men there was no such relation. Lack of physical activity showed only a weak (non-significant) increased risk of death due to CHD. Diabetes was also found to be an important risk factor for mortality from CHD, especially among women, being seven times as high as among non diabetics. A test of sex differences revealed that there were two significant interactions, namely between sex and overweight, and between sex and age. Background variables in relation to mortality from all cardiovascular diseases (CVD) were also studied. There were of course many similarities between the effects of the background variables in both the disease groups, but there were interesting differences too, e.g. overweight turned out to be a significant risk factor also for men and physical inactivity for women.     

Cholesterol-lowering therapy in women and elderly patients with myocardial infarction or angina pectoris: findings from the Scandinavian Simvastatin Survival Study (4S)

BACKGROUND: The Scandinavian Simvastatin Survival Study (4S) demonstrated pronounced reductions in mortality and major coronary events in a cohort of patients with established coronary heart disease (CHD). The present study provides a detailed, post hoc assessment of the efficacy and safety of simvastatin therapy in the following subgroups of 4S patients: those > or = 65 years of age, those < 65 years of age, women, and men. METHODS AND RESULTS: The 4S cohort of 4444 CHD patients included 827 women and 1021 patients > or = 65 years of age. Total cholesterol at baseline was 5.5 to 8.0 mmol/L with triglycerides < or = 2.5 mmol/L. Patients were randomized to therapy with simvastatin 20 to 40 mg daily or placebo for a median follow-up period of 5.4 years. End points consisted of all-cause and CHD mortality, major coronary events (primarily CHD death and nonfatal myocardial infarction), other acute CHD and atherosclerotic events, hospitalizations for CHD and cardiovascular events, and coronary revascularization procedures. Mean changes in serum lipids were similar in the different subgroups. In patients > or = 65 years of age in the simvastatin group, relative risks (95% confidence intervals) for clinical events were as follows: all-cause mortality, 0.66 (0.48 to 0.90); CHD mortality, 0.57 (0.39 to 0.83); major coronary events, 0.66 (0.52 to 0.84); any atherosclerosis-related event, 0.67 (0.56 to 0.81); and revascularization procedures, 0.59 (0.41 to 0.84). In women, the corresponding figures were 1.16 (0.68 to 1.99); 0.86 (0.42 to 1.74), 0.66 (0.48 to 0.91), 0.71 (0.56 to 0.91), and 0.51 (0.30 to 0.86), respectively. CONCLUSIONS: Cholesterol lowering with simvastatin produced similar reductions in relative risk for major coronary events in women compared with men and in elderly (> or = 65 years of age) compared with younger patients. There were too few female deaths to assess the effects on mortality in women. Because mortality rates increased substantially with age, the absolute risk reduction for both all-cause and CHD mortality in simvastatin-treated subjects was approximately twice as great in the older patients.     

Plasma interleukin-6 and soluble IL-6 receptors are associated with psychological well-being in aging women.

Objective: This study tested the hypothesis that psychological well-being would predict lower plasma levels of inflammatory factors in aging women. Design: One hundred thirty-five women ages 61-91 years (M = 74.5 years) participated in this study. After completing self-administered questionnaires in their homes, participants stayed overnight at the General Clinical Research Center (GCRC) at the University of Wisconsin-Madison. Blood samples for cytokine analyses were obtained in participants' homes after the GCRC visit. Main Outcome Measures: Psychological well-being and ill-being, history of health problems, and health behaviors were assessed via self-administered questionnaires. Detailed medical history and concurrent health measures were obtained during the GCRC stay. Enzyme-linked immunosorbent assays were used to determine interleukin-6 (IL-6) and soluble IL-6 receptor (sIL-6R) concentrations in plasma. Results and Conclusion: Regression analyses showed that plasma IL-6 levels were lower in women scoring higher on positive relationships, whereas sIL-6R levels were lower in women scoring higher on purpose in life, even after a variety of sociodemographic and health factors were controlled. These outcomes, combined with the absence of significant links with other measures of well-being and ill-being, suggest selective patterns of association between later life inflammatory processes and psychological factors, particularly those focused on positive ties with others and purposeful engagement.

Hostility, social support, and coronary heart disease in the National Heart, Lung, and Blood Institute Family Heart Study

This cross-sectional study investigated the association of hostility and social support to coronary heart disease (CHD) in 2 groups of men and women: those with a familial predisposition for CHD (high-risk sample) and a randomly selected group. The hypothesis was that hostility and low social support would be associated with CHD, and would have a greater effect in the high-risk group. The random sample contained 2,447 individuals (47.1% male) from 576 families, and the high-risk sample consisted of 2,300 people (45.5% male) from 542 families. Odds ratios (OR) and their 95% confidence intervals were calculated using generalized estimating equations (GEE) for logistic regression. Family was specified as the clustering variable, and robust SEEs were obtained to account for dependence of the data within families. After controlling for age, education, body mass index, exercise, smoking history, drinking history, and drinking >5 drinks a day, hostility was associated with a history of coronary bypass surgery or coronary angioplasty in high-risk men (OR 1.21) and a history of myocardial infarction in high-risk women (OR 1.39). High-risk women with high social support had reduced odds of a previous myocardial infarction (OR 0.76), whereas women with high network adequacy in the random sample had reduced risk of myocardial infarction (OR 0.41) and angina (OR 0.49). A ratio of high hostility to low social support was associated with past myocardial infarction in high-risk women (OR 2.47) and a history of angina (OR 2.02) in the random sample men. These results suggest that high hostility and low social support are associated with some manifestations of CHD after controlling for adverse health behaviors.     

Life transitions and mental health in a national cohort of young Australian women.

Young adulthood, a time of major life transitions and risk of poor mental health, may affect emotional well-being throughout adult life. This article uses longitudinal survey data to examine young Australian women's transitions across 4 domains: residential independence, relationships, work and study, and motherhood. Changes over 3 years in health-related quality of life, optimism, depressive symptoms, stress, and life satisfaction, were examined in relation to these transitions among 7,619 young adult participants in the nationally representative Australian Longitudinal Study on Women's Health. Positive changes in mental health occurred for women moving into cohabitation and marriage, whereas reductions were observed among those experiencing marital separation or divorce and those taking on or remaining in traditionally "feminine" roles (out of the workforce, motherhood). The data suggest that women cope well with major life changes at this life stage, but reductions in psychological well-being are associated with some transitions. The findings suggest that preventive interventions to improve women's resilience and coping might target women undergoing these transitions and that social structures may not be providing sufficient support for women making traditional life choices.

Coping with anger-provoking situations, psychosocial working conditions, and ECG-detected signs of coronary heart disease.

This study explored the association among coping, psychosocial work factors, and signs of coronary heart disease (CHD) among prison staff (777 men, 345 women). Electrocardiogram (ECG) recordings at rest, health examinations, and a questionnaire were used. A high level of covert coping in men and a low level of open coping in women showed the strongest association with signs of CHD. Among several traditional biological and lifestyle risk factors, only age and systolic blood pressure in men and none in the case of women were significantly associated with CHD signs in the final multivariate regression analyses. A coping style of repressed emotions and actions in anger-provoking situations, independent of traditional risk factors, seems to be associated with a prevalence of ECG signs in male and female prison staff.

Recording of the saphenous vein compliance by an ultrasonic echo-tracking device in the dog: effects of S 18149

BACKGROUND AND PURPOSE: Studies on risk factors for stroke have been less intensive than those for coronary disease. Only a few studies have addressed the question of the role of heredity in the occurrence of stroke. We analyzed whether a positive parental history of cardiovascular disease predicts the risk of stroke independently from other risk factors and whether the role of parental history varies by age and stroke subtypes. METHODS: This study was a prospective follow-up of 14371 middle-aged men and women. A positive parental history of cardiovascular disease was defined as either stroke or coronary disease before the age of 60 years. The end point of the follow-up was an incident case of stroke. Multivariate analyses were performed with the Cox proportional hazards model. RESULTS: The risk ratio of stroke after multifactorial adjustment (age, smoking, blood pressure, cholesterol, diabetes, and education) associated with a positive parental history of stroke was 1.89 (P = .004) in men and 1.80 (P = .007) in women. The association between parental history of stroke and the risk of stroke was stronger among subjects aged 25 to 49 years than among older subjects. Parental history of coronary disease was not associated with the risk of stroke in men, but in women it had a borderline significant association with the risk of ischemic stroke. CONCLUSIONS: A positive parental history of stroke predicted the risk of stroke independently from the other risk factors.     

Plasma viscosity and the risk of coronary heart disease: results from the MONICA-Augsburg Cohort Study, 1984 to 1992

Plasma viscosity is determined by various macromolecules, eg, fibrinogen, immunoglobulins, and lipoproteins. It may therefore reflect several aspects involved in cardiovascular diseases, including the effects of classic risk factors, hemostatic disturbances, and inflammation. We examined the association of plasma viscosity with the incidence of a first major coronary heart disease event (CHD; fatal and nonfatal myocardial infarction and cardiac death; n=50) in 933 men aged 45 to 64 years of the MONICA project of Augsburg, Germany. The incidence rate was 7.23 per 1000 person-years (95% confidence interval [CI], 5.37 to 9.53), and the subjects were followed up for 8 years. All suspected cases of an incident CHD event were classified according to the MONICA protocol. There was a positive and statistically significant unadjusted relationship between plasma viscosity and the incidence of CHD. The relative risk of CHD events associated with a 1-SD increase in plasma viscosity (0.070 mPa x s) was 1.60 (95% CI, 1.25 to 2.03). After adjustment for age, total cholesterol, high density lipoprotein cholesterol, smoking, blood pressure, and body mass index, the relative risk was reduced only moderately (1.42; 95% CI, 1.09 to 1.86). The relative risk of CHD events for men in the highest quintile of the plasma viscosity distribution in comparison with the lowest quintile was 3.31 (95% CI, 1.19 to 9.25) after adjustment for the aforementioned variables. A large proportion of events (40%) occurred among men in the highest quintile. These findings suggest that plasma viscosity may have considerable potential to identify subjects at risk for CHD events.     

Preinfarction blood pressure and smoking are determinants for a fatal outcome of myocardial infarction: a prospective analysis from the Finnmark Study

BACKGROUND: Serum cholesterol levels, blood pressure, and smoking are the classic coronary risk factors, but what determines whether a myocardial infarction will be fatal or not? OBJECTIVE: To investigate cardiovascular risk factors that may influence survival in subjects with coronary heart disease (myocardial infarction and sudden death). SUBJECTS AND METHODS: All inhabitants aged 35 to 52 years in Finnmark County, Norway, were invited to a cardiovascular survey in 1974-1975 and/or 1977-1978. Attendance rate was 90.5%. A total of 6995 men and 6320 women were followed up for 14 years with regard to incident myocardial infarction and sudden death. Predictors for 28-day case fatality rate after first myocardial infarction were analyzed. RESULTS: During 186 643 person-years, 635 events among men and 125 events among women were registered. The case fatality rate was 31.6% in men and 28.0% in women (P =.50). Among men (women) with baseline systolic blood pressure lower than 140 mm Hg, the 28-day case fatality rate was 24.5% (22.6%), among those with systolic blood pressure of 140 through 159 mm Hg, the case fatality rate was 35.6% (28.2%), and among those with systolic blood pressure of 160 mm Hg or higher, the case fatality rate was 48.2% (41.7%). Of the 760 subjects with myocardial infarction, 348 died during follow-up. In Cox regression analysis, systolic blood pressure at baseline was strongly related to death (relative risk per 15 mm Hg, 1.22; 95% confidence interval, 1.13-1.31). Daily smoking at baseline (relative risk, 1.40; 95% confidence interval, 1.07-1.85) and age at time of event (relative risk per 5 years, 1.12; 95% confidence interval, 1.01-1.24) were additional significant risk factors, while total serum and high-density lipoprotein cholesterol levels were unrelated to survival. Similar results were obtained with diastolic blood pressure in the model. CONCLUSIONS: Preinfarction blood pressure was an important predictor of case fatality rate in myocardial infarction. Daily smoking and age were additional significant predictors.     

QT interval as a cardiac risk factor in a middle aged population

OBJECTIVE: To evaluate the value of QT interval as a cardiac risk factor in middle aged people. METHODS: The association between QT interval and cardiac risk factors and mortality in a middle aged Finnish population of 5598 men and 5119 women was evaluated over a 23 year follow up. To adjust the QT interval confidently for heart rate, a nomogram was constructed from the baseline electrocardiograms separately for men and women. RESULTS: Nomogram-corrected QT interval (QTNc) prolongation was associated with elevated blood pressure and signs of cardiovascular disease; QTNc shortening was associated with smoking. Over 10% prolongation of QTNc predicted death in men with heart disease: adjusted relative risk (RR) was 2.17 (95% confidence interval 0.67-7.45) for sudden death; 2.12 (1.25-3.59) for total cardiovascular mortality; and 1.92 (1.23-3.00) for all cause mortality. In healthy men the increase in RR was not significant: sudden death, 1.48 (0.67-3.25); total cardiovascular mortality, 1.25 (0.92-1.70); all cause mortality, 1.21 (0.96-1.53). However, healthy men with long QTNc in the lowest heart rate quartile exhibited an RR of 2.75 (1.00-7.40) for sudden death. Over 10% shortened QTNc predicted cardiovascular death in men with heart disease who smoked; RR 3.72 (1.45-9.54). Non-smoking men with short QTNc had low mortality risks irrespective of possible signs of cardiovascular disease. The trends in mortality risks were similar but weaker for women. CONCLUSIONS: In a middle aged population, prolonged QT interval predicts cardiac mortality in men with signs of cardiovascular disease. In women and healthy men this risk is weak and may reflect subclinical heart disease. A shortened QT interval predicts death in men with heart disease who smoke.     

Socioeconomic inequalities in coronary heart disease and stroke mortality among Australian men, 1979-1993

BACKGROUND: During the 1970s in Australia, mortality from coronary heart disease (CHD) and stroke was higher among lower socioeconomic groups and inequalities were widening. This analysis examines subsequent trends in socioeconomic inequalities, with reference to socioeconomic patterns in major cardiovascular risk factors. METHODS: Socioeconomic status was defined by occupation. Age-standardized mortality rates were calculated for men aged 25-64, using death registration data and labour force estimates for 1979-1993. Risk factor data were taken from three cross-sectional population surveys conducted in 1980, 1983 and 1989. RESULTS: Men in manual occupations were at least 35 percent more likely to die from CHD than men in professional occupations and 60 percent more likely to die from stroke. Their 5-year population risk of a coronary event was 30 percent higher. Since 1979, both groups experienced reductions in coronary risk and mortality. CONCLUSIONS: Socioeconomic inequalities in CHD mortality continued to widen during the early 1980s, stabilized thereafter and persisted into the 1990s. Decreases in blood pressure and smoking prevalence contributed most to declines in coronary risk and to socioeconomic differentials.     

Risk of coronary heart disease and activation of factor XII in middle-aged men

Increased activity is known to be present in the extrinsic, intrinsic, and final common pathways of the hemostatic system in men at high risk of coronary heart disease (CHD), but the status of the contact system of coagulation in this condition is uncertain. Plasma levels of activated factor XII (XIIa), the initial product of contact activation, have therefore been measured by ELISA in 2464 men aged 51 to 62 years, clinically free of CHD, who were taking part in a prospective cardiovascular survey based in general medical practices. Statistically significant, independent, and positive associations of XIIa were found with serum cholesterol and triglyceride concentrations, blood pressure, body mass index, factor VII activity, plasma fibrinogen concentration, and tobacco smoking, all associated with CHD. Plasma XIIa also increased with recent alcohol intake. Men in the highest quintile of risk according to their conventional risk factors had a mean XIIa of 2.07 ng/mL (95% confidence interval 1.99-2.16), 31% higher than that of men in the lowest quintile (1.58; 95% confidence interval 1.51-1.65). Thus, the contact system of coagulation appears to be activated when CHD risk is increased. Furthermore, the independent associations of XIIa with the major conventional CHD risk factors and its broad range of values in the general population (0.1 to 12.5 ng/mL), combined with a relatively low day-to-day variability in individuals (the within-person component of its total variation being 14.7%), suggest its potential usefulness as a marker of atherosclerotic vascular damage.     

Helicobacter pylori infection and coronary heart disease in the North Glasgow MONICA population

AIM: Recent evidence suggests that Helicobacter pylori infection is associated with coronary heart disease. We investigated whether H. Pylori infection is related to prevalent coronary heart disease, in a random sample of 1428 men and women aged 25-74 years. METHODS AND RESULTS: Coronary heart disease was assessed by questionnaire and electrocardiography (ECG). Standard risk factors for coronary heart disease, fibrinogen concentration and serum concentrations of H. pylori-specific IgG antibody were measured. H. pylori seropositivity increased with age (P < or = 0.001) and was significantly more prevalent in men than women. H. pylori infection was associated with current smoking and a higher systolic blood pressure in men but not in women. There was no significant increase in the odds ratio in those seropositive for H. pylori with regard to any manifestation of coronary heart disease, after adjustment for age, standard cardiovascular risk factors and social class. Likewise, age-adjusted plasma fibrinogen was no higher in seropositives. CONCLUSION: Seropositivity to H. pylori is associated with a trend towards a greater prevalence of coronary heart disease. However, that association is likely to be spurious and can be adequately explained by the much stronger association of H. pylori infection with age and social class, both of which are linked with coronary heart disease.     

Depression and risk of coronary heart disease in elderly men and women: New Haven EPESE, 1982-1991. Established Populations for the Epidemiologic Studies of the Elderly

BACKGROUND: Results of several recent studies suggest that depression is predictive of incident coronary disease. However, few studies have examined this relationship in the elderly, the age at which most coronary heart disease (CHD) becomes clinically manifest. METHODS AND RESULTS: Data are from the New Haven, Conn, cohort (N = 2812) of the Established Populations for the Epidemiologic Studies of the Elderly project. Baseline information on depressive symptoms and CHD risk factors was collected during an in-person interview in 1982. Nonfatal myocardial infarctions were identified through monitoring of admissions to local hospitals and were validated by medical chart review. Cause of death was obtained from death certificates for all deceased participants. Outcomes were defined as CHD deaths (n = 255) and total incident CHD events (n = 391) between January 1, 1982, and December 31, 1991. There was no association between depressive symptoms and CHD outcomes in men. Among women, depressive symptoms were associated with an age-adjusted relative risk of 1.03 (per unit increase on the symptom scale) for CHD mortality (P=.001) and total CHD incidence (P=.002). These associations were largely unaffected by adjustment for established CHD risk factors but were reduced to nonsignificant levels after additional adjustment for impaired physical function. Additional analysis showed a significant association for depressive symptoms among women who had no physical function impairments or who survived at least 3 years without an event. CONCLUSION: Depressive symptoms may not be independent risk factors for CHD outcomes in elderly populations in general but may increase risk among relatively healthy older women.     

Influence of delayed staging laparotomy after laparoscopic removal of ovarian masses later found malignant

OBJECTIVE: To study the prevalence of cardiovascular risk factors in native urban Asian Indians and to look for the occurrence of clustering of these factors. RESEARCH DESIGN AND METHODS: The study included 953 subjects (532 men and 421 women), aged > or = 40 years, selected from a population survey for diabetes, which was conducted in 1994 in Madras, Tamil Nadu, India. Measurements of anthropometry, blood pressure, plasma lipid profile, glucose tolerance, plasma insulin response, and electrocardiogram were made. Based on the normal ranges derived from the population study, abnormalities in anthropometric values, plasma lipids, and insulin values were determined. Age-adjusted prevalences of the abnormalities were calculated using data from a 1991 urban census in Madras. The expected prevalences of the abnormalities in isolation and in combinations were calculated and compared with the corresponding observed figures. RESULTS: The prevalences of risk factors were in the order of central adiposity > dyslipidemia > hyperinsulinemia (2-h) > glucose intolerance > obesity > hypertension. The age-adjusted prevalence of coronary heart disease (CHD) was 3.9% (3.5% in men and 4.5% in women, NS), and T wave inversion was seen in an additional 10.3%. Isolated prevalences of all factors, except hypertension, were in lower frequency than expected. Combinations of each risk factor with one or two more risk factors occurred more frequently (1.3-4 times) than expected by chance. Impaired glucose tolerance and dyslipidemia showed association with hyperinsulinemia, whereas hypertension did not show such an association. CONCLUSIONS: Clustering of the cardiovascular risk factors or the components of insulin resistance syndrome occurs in the native Asian Indian population. This finding under-scores the need for preventive aspects of metabolic disorders and CHD.
