Why the study?
Does oral verapamil improve angina threshold and myocardial oxygen demand in patients with effort angina and fixed obstructive coronary artery disease?
Does oral verapamil improve angina threshold and myocardial oxygen demand in patients with effort angina and fixed obstructive coronary artery disease?
Oral verapamil relieves pacing-induced angina primarily by decreasing myocardial oxygen demand through lower arterial pressure, without deteriorating left ventricular function.
No takes yet. Share an insight, caveat, or question.
May raise angina threshold in effort angina; single case leaves open need for controlled confirmation.
Rouleau et al. (1983) studied this question.
