Does sublingual nifedipine improve hemodynamics and myocardial metabolism in patients with angina pectoris?
Sublingual nifedipine relieves angina primarily through afterload reduction and decreased myocardial oxygen consumption, with potential additional mechanisms such as increased collateral flow or direct epicardial dilation.
Emanuelsson et al. (1983) studied this question.
