title: Potency of vascular risk factors as the basis for antihypertensive therapy.
abstract: Hypertension is a powerful predisposing risk factor for cardiovascular disease at all ages and in both sexes. Epidemiological assessment indicates the largest risk ratios for stroke and congestive heart failure (CHF), but coronary heart disease (CHD) is the most common and most lethal sequela of hypertension. Examination of the risk of cardiovascular sequelae in the hypertensive population indicates that this is not uniform and varies over a 10-fold range, depending on the associated risk factors. Systolic pressure merits greater consideration than the diastole pressure because isolated systolic hypertension is a powerful cardiovascular risk at all ages. Furthermore, recent trials have indicated the benefit of therapy for systolic-based hypertension in the elderly, even using a diuretic, for coronary disease as well as stroke. Persons with hypertension have a high prevalence of associated cardiovascular risk factors, including elevated cholesterol, reduced HDL-C, diabetes, left ventricular hypertrophy (LVH), and obesity. About 9% under the age of 65 years have an associated overt cardiovascular disease; above age 65 about 30% are so afflicted. Each of these risk factors can double the risk associated with hypertension. Because they are so common, a large fraction of the disease sequelae of hypertension is attributable to these associated risk factors. The high risk of coronary disease in hypertensive patients is concentrated in those with a high total/HDL-cholesterol ratio, impaired glucose tolerance, high fibrinogen, ECG abnormalities, and cigarette smokers. Stroke risk in hypertensive persons is concentrated in those with cardiovascular disease, diabetes, atrial fibrillation, LVH and cigarette smoking.(ABSTRACT TRUNCATED AT 250 WORDS)
