对中等度充血心衰病人进行血液超滤可改善临床状况,缓和神经体液反应,增加尿流,促进过剩的血管外液体吸收,肺内促进氧弥散,增加氧供,减少肺内分流及减轻肺的僵硬度,减少呼吸肌做功,减轻心室后负荷。方法 36例中等心衰,临床状况稳定,血电解质正常,血浆地高辛水平在正常范围。新发心梗(1年内)、心绞痛、原发心瓣膜病、间歇性跛行、原发性或纤维性肺血管病、窦房结或房室结功能障碍、运动引起的室性心律失常、人工起搏均排除在外。36例病人分为2组,A组18例,进行血超滤,B组为
Blood ultrafiltration in patients with moderate-to-severe congestive heart failure can improve clinical outcomes, ease neurohumoral responses, increase urinary flow, promote excess extravascular fluid absorption, promote oxygen diffusion in the lungs, increase oxygen supply, reduce intrapulmonary shunting, and reduce lung Stiffness, reduce respiratory muscle work, reduce ventricular afterload. Methods 36 cases of moderate heart failure, clinical stability, normal blood electrolytes, plasma digoxin levels in the normal range. New onset myocardial infarction (within 1 year), Angina pectoris, Primary valvular disease, Intermittent claudication, Primary or fibrotic pulmonary vascular disease, Sinus node or atrioventricular node dysfunction, Exercise induced ventricular arrhythmia, Artificial Pacing are excluded. 36 patients were divided into two groups, 18 cases in group A, blood ultrafiltration, B group
