title: [Angiographic course of coronary atherosclerosis in angina pectoris. Its relation to 2 years' treatment with propranolol, nifedipine and nitrates].
abstract: Calcium antagonists and beta-blockers may retard or inhibit atherogenesis. We tested whether nifedipine or propranolol may retard or induce regression of coronary atherosclerosis in man. In selected population of 113 patients with effort angina and proven coronary artery disease, the coronary cineangiographic pattern after 2 year therapy with nifedipine (Group 1, 39 patients), propranolol (Group 2, 36 patients), or isosorbide dinitrate (control group, 38 patients) was compared to the pre-treatment pattern. After 2 years the disease evolved to a different extent in the 3 groups. The number of lesions with evidence of progression was significantly smaller after nifedipine (14), and larger after propranolol (39) as compared with controls (24). Patients with evidence of progression of old lesions, and appearance of new lesions were significantly fewer in Group 1 than in Group 2 and in control patients. Thus, nifedipine seemed more protective than either of the other drugs against coronary atherosclerosis. The coronary risk factors were within normal limits in the nifedipine treated group and remained so with treatment supporting that they were likely dissociated from influences on atherosclerosis. The evolution, at least as judged by the number of lesions with progression, appeared significantly (p less than 0.01) worse with propranolol than with isosorbide dinitrate. This may prospect that nitrate contrasted the evolution of the disease, or that propranolol made it worse, possibly through unfavourable modifications of serum lipids (28% rise of total triglyceride and 25% decrease of HDL cholesterol were already detectable at 12 months in Group 2).
