Left ventricular end-diastolic pressures following selective coronary arteriography

Abstract

Left ventricular pressures were analyzed before and after left ventricular and coronary artery angiography in 40 subjects. Seven “normal” patients demonstrated no rise in left ventricular end-diastolic pressure following angiography. Two patients with cardiomyopathy and 27 of 31 patients with coronary artery disease demonstrated significant rises in end-diastolic pressure, proportional to the extent of the disease, following angiography. Of the 4 failing to show a rise, nitroglycerin had been administered prior to pressure recordings in 3.
