Right ventricular hemodynamics were evaluated in 179 patients with coronary artery disease to determine the effects of chronic ischemia on right ventricular diastolic pressure. Abnormal right ventricular filling pressures occurred only in patients with an abnormal right ventricular systolic pressure or an abnormal left ventricular end-diastolic pressure. Of the 63 patients whose right ventricle was stressed by an increased systolic load secondary to passive pulmonary hypertension, 44 (72 percent) had an abnormal right ventricular end-diastolic pressure. In this group obstruction of vessels serving the right ventricular free wall or septum, or both, was almost universal (43 of 44, 98 percent) and a significantly increased incidence of inferior infarction (P less than 0.05) was noted. Such obstruction was significantly less frequent in patients with normal filling pressures (10 of 17, 59 percent; P less than 0.001). Compared with patients with coronary artery disease, patients with passive pulmonary hypertension due to aortic stenosis or mitral stenosis had significantly greater degrees of pulmonary hypertension (P less than 0.05) yet slightly lesser elevations of right ventricular end-diastolic pressure. These data suggest that in patients with ischemic heart disease the right ventricle exhibits diastolic dysfunction at lower levels of afterload stress than it would with normal coronary blood flow.
