为确定扩张型心肌病、心肌炎和心脏移植对血浆免疫反应性心钠素(ANF)和心室充盈压之间关系的影响,测定右心房血浆心钠素水平、肺动脉嵌顿压和右心房压力。对象为48例扩张型心肌病、20例继发于心肌炎的扩张型心肌病和34例曾作心脏移植的患者。在扩张型心肌病患者,心钠素水平同肺动脉嵌顿压和右心房压力明显相关.然而, To determine the effect of dilated cardiomyopathy, myocarditis, and heart transplantation on the relationship between plasma immunoreactive atrial natriuretic peptide (ANF) and ventricular filling pressure, right atrial plasma atrial natriuretic peptide levels, pulmonary artery occlusion pressure, and right atrial pressure were measured. Subjects were 48 cases of dilated cardiomyopathy, 20 cases of dilated cardiomyopathy secondary to myocarditis and 34 cases of patients who had undergone cardiac transplantation. In patients with dilated cardiomyopathy, atrial natriuretic peptide levels correlate significantly with pulmonary artery occlusion pressure and right atrial pressure.However,
