Out of 34 consecutive patients with angina and treated with nifedipine, two subjects (5.8 percent) showed a significant increase of transient myocardial ischemic episodes during the period of treatment, as assessed by continuous Holter ECG monitoring. In both these patients, a large proportion of ischemic episodes happened to be asymptomatic. A relationship between nifedipine intake, heart rate increase, and number of ischemic episodes was observed. This occasional aggravation of myocardial ischemia could be related to an increase in myocardial oxygen demand medicated through a drug-induced reflex tachycardia.
