title: Immediate and long-term effects of nicardipine, at rest and during exercise, in patients with coronary artery disease.
abstract: Haemodynamic effects of nicardipine were studied in 12 patients with documented coronary artery disease. Following nicardipine 10 mg, given intravenously to patients at rest, the heart rate increased, mean arterial pressure decreased, cardiac index increased, and systemic vascular resistance decreased significantly. Compared with the control exercise values, significant increases in heart rate and cardiac index and significant decreases in mean arterial pressure, systemic vascular resistance, and left ventricular end diastolic pressure occurred when nicardipine, 10 mg i.v., was given to the patients during exercise. All 12 patients complained of angina during the exercise phase, but following treatment with nicardipine, 10 mg i.v., only four patients reported angina when exercising to the same level. Exercise capacity on oral nicardipine treatment tended to increase whilst the ejection fraction response to exercise did not change. Thus, nicardipine was a potent vasodilator, which produced a marked reduction of systemic vascular resistance and left ventricular end diastolic pressure during exercise.
