<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">右心衰竭<span style="color: black;">一般</span><span style="color: black;">指的是</span>右心室在收缩期<span style="color: black;">不可</span>打出足够的血液，为肺动脉供血以及为肺循环供血，而在舒张期<span style="color: black;">不可</span>使体循环的血液<span style="color: black;">即时</span>经过上下腔静脉反流回右心房，从而进入右心室，<span style="color: black;">因此</span>表现为体循环淤血。最初的症状是身体低垂部位的水肿，随着病情的加重，<span style="color: black;">能够</span><span style="color: black;">显现</span>全身水肿以及腹水、胸水、心包积液等。<span style="color: black;">病人</span><span style="color: black;">必须</span><span style="color: black;">按照</span>右心功能衰竭的原发<span style="color: black;">疾患</span>给予针对病因治疗，对症治疗<span style="color: black;">能够</span><span style="color: black;">运用</span>利尿剂，血管扩张剂，正性肌力的<span style="color: black;">药品</span>以及改善心室重构的<span style="color: black;">药品</span>。经过积极的治疗以后，<span style="color: black;">能够</span>使体循环淤血的症状减轻，病情好转，<span style="color: black;">然则</span>要规范<span style="color: black;">长时间</span>地<span style="color: black;">吃下</span><span style="color: black;">药品</span>。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">右心衰竭<span style="color: black;">原由</span>有以下几种，肺部<span style="color: black;">疾患</span><span style="color: black;">引起</span>，<span style="color: black;">有些</span>肺动脉高压、急性大面积肺栓塞、大面积肺梗死、肺动脉瓣狭窄等，<span style="color: black;">导致</span>右心射入肺脏血的压力<span style="color: black;">显著</span>增大，<span style="color: black;">长时间</span>发展下去，右心<span style="color: black;">连续</span>高压力负荷工作，从而<span style="color: black;">显现</span>衰竭。心脏<span style="color: black;">疾患</span><span style="color: black;">引起</span>，正常血液从体循环回流至右心，右心把血液射入肺脏，肺脏再回流至左心，左心射入体循环。当<span style="color: black;">上下</span>心之间有<span style="color: black;">缺失</span>，<span style="color: black;">例如</span>房间隔<span style="color: black;">缺失</span>、室间隔<span style="color: black;">缺失</span>等，右心<span style="color: black;">不仅</span><span style="color: black;">必须</span>容纳体循环回流的血液，还要接受从左心<span style="color: black;">经过</span><span style="color: black;">缺失</span>部位泵入的血液，<span style="color: black;">长时间</span>发展，右心血容量越来越多，<span style="color: black;">显现</span>右心扩大直至衰竭。</p>
