Abstract: | The aim this work was to assess retrospectively the history of hypertension in patients admitted for cerebrovascular diseases. Two hundred and forty eight patients were studied (69% with ischemic strokes, 24% with hemorrhagic strokes and 7% with transient ischemic attacks. 76% of cases had a history hypertension with an evolution of ten years or more in 81% of cases. No differences in the prevalence of hypertension was observed among the different types of strokes. Of the 139 patients in whom the severity of hypertension was registered, 37% had mild, 45% moderate, 15% severe and 3% systolic hypertension. Those with severe hypertension had a higher incidence of hemorrhagic stroke. Fundoscopic examination was abnormal in 81% of the 64 patients in whom it was performed, left ventricular hypertrophy was found in 62% of the 146 patients in whom it was investigated. 51% of patients were receiving anti hypertensive treatment and it was effective in 26% of them. Thirty one percent of subjects had old lesions in the CAT scan; these subjects had a similar prevalence of hypertension and effectiveness of treatment than patients without old lesions. It is concluded that a history of more than ten years of hypertension is a risk factor for cerebrovascular disease, that severe hypertension is mostly associated to hemorrhagic strokes and that only 26% of patients with stroke had and adequate anti hypertensive treatment. |
