The impact of treating hypertension on coronary artery disease has been less than anticipated from epidemiologic studies of cardiovascular risk factors. It has been suggested that adverse effects on lipids of traditional diuretic or beta-blocker regimens may diminish the potential benefits of antihypertensive therapy. Patients with mild to moderate systemic hypertension and normal serum lipids (n = 191) were randomly assigned to doxazosin or atenolol. After dose titration to goal diastolic blood pressure of < or = 90 mm Hg, patients continued treatment for a further 24 weeks. The principal outcome measurement was overall coronary artery disease risk using the Framingham formula. Relative risk of coronary artery disease was reduced to 92.4% of baseline (p = 0.144) for evaluable patients taking atenolol (n = 71), and to 74.6% (p = 0.0001) for patients taking doxazosin (n = 51): atenolol versus doxazosin, p = 0.0074. In patients who met the strict Framingham criteria for age, total cholesterol and high density lipoprotein cholesterol, the relative risk of coronary artery disease for patients taking atenolol (n = 23) was reduced to 86.2% of baseline (p = 0.082), and to 67.4% (p = 0.0004) for patients taking doxazosin (n = 18): atenolol versus doxazosin, p = 0.049. Alpha blockade with doxazosin was more effective than beta blockade with atenolol in reducing the risk of coronary artery disease in hypertensive patients because of the beneficial effects of doxazosin on high-density lipoprotein cholesterol. Overall withdrawal rate was greater in the alpha-blocker group because of a lower response rate and more adverse events.
