Abstract: | High lipoprotein(a) [Lp(a)] has been observed in patients with ischemic heart disease and cerebrovascular disease. Lp(a) is actually thought to be an independent risk factor for coronary disease. We therefore carried out a case-control study, evaluating plasma Lp(a) in 61 patients with angiographically documented peripheral arterial disease (PAD) and in 61 age- and sex-matched patients with no cardiovascular disease. General risk factors for vascular disease were also taken into account. Lp(a) was significantly higher in patients than controls (257.0 +/- 34.8 vs 146.5 +/- 23.5 mg/l p < 0.05), as were cigarette smoking, diabetes, cholesterolemia, fibrinogenemia and the waist-to-hip circumference ratio. Stepwise logistic regression analysis showed that, in addition to cigarette smoking, diabetes, cholesterol and fibrinogen, Lp(a) is a significant independent risk indicator for PAD. This result suggests that high plasma Lp(a) is associated with enhanced risk of PAD and must therefore be evaluated alongside traditional risk factors. |
