What is the long-term efficacy of calcium channel blocker therapy for angina pectoris resulting from small-vessel coronary artery disease and abnormal vasodilator reserve?
A 1985 study published in the American Journal of Cardiology evaluated the long-term efficacy of calcium channel blocker therapy for angina pectoris resulting from small-vessel coronary artery disease and abnormal vasodilator reserve. The results of the study showed that calcium channel blockers were effective in reducing the frequency and severity of angina attacks, as well as improving exercise tolerance. Furthermore, the study concluded that the long-term outcomes of calcium channel blocker therapy were generally positive, with few adverse effects or recurrences of angina.
