Abstract
Proatherogenic changes in serum lipid concentrations have been implicated as one of the major risk factors in the development of coronary artery disease. In a double-blind study, the new alpha 1-adrenoceptor inhibitor, doxazosin, was compared with atenolol for effects on the serum lipid profile. Ninety-six hypertensive patients were treated for up to 1 year with either doxazosin or atenolol once daily. There were statistically significant differences (p less than or equal to 0.01) between doxazosin and atenolol after 20 to 52 weeks of treatment in changes from baseline total triglyceride levels, high density lipoprotein (HDL) cholesterol levels and HDL/total cholesterol ratio. The percentage of change from baseline and the statistical significance of the difference between treatment groups were: total triglycerides, doxazosin -5.9%, atenolol +32.4% (p = 0.01); HDL cholesterol, doxazosin +7.2%, atenolol -5.6% (p = 0.007) and HDL/total cholesterol ratio: doxazosin +8.7%, atenolol -6.2% (p = 0.006). All mean changes were in favor of doxazosin therapy. In addition, doxazosin treatment beneficially decreased total serum cholesterol levels (-1.6%) compared with atenolol (+0.6%), although not to a significant degree. The differences were maintained in the cohort of 67 patients treated for a full year. The favorable change exerted by doxazosin on the lipid profile suggests that it may have a beneficial influence on the lipid risk factor. These results, together with the sustained decrease in blood pressure achieved for up to 1 year of therapy, suggest that doxazosin may reduce the risk of coronary artery disease in susceptible patients.
