平常的慢性心力衰竭的临床表现和治疗
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">近三十年来，人们对心力衰竭的认识有了很大的<span style="color: black;">加强</span>，对心力衰竭的诊断和治疗取得了很大的进步。<span style="color: black;">那样</span>今天来重点学习下<span style="color: black;">平常</span>的慢性心力衰竭的临床表现和治疗，让<span style="color: black;">咱们</span><span style="color: black;">一块</span>来<span style="color: black;">瞧瞧</span>。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">【临床表现】</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">(一)慢性左心衰竭 以肺淤血及心排血量减少表现为主。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">症状</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">1.<span style="color: black;">呼气</span>困难:①劳力性<span style="color: black;">呼气</span>困难，是最早<span style="color: black;">显现</span>的症状;②夜间阵发性<span style="color: black;">呼气</span>困难;③端坐<span style="color: black;">呼气</span>;④急性肺水肿，为急性左心衰最严重的临床表现。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">2.咳嗽、咳痰、咯血。白色浆液性<span style="color: black;">泡泡</span>状痰为其特点。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">3.乏力、疲倦、头昏、心慌。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">4.少尿及肾功能损害症状。少尿，血尿素氮、肌酐<span style="color: black;">上升</span>等。</p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">肺部湿性啰音，可从局限于肺底直至全肺;心脏扩大，肺动脉瓣区第二心音亢进及舒张期奔马律。脉搏表现为交替脉。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">(二)慢性右心衰竭 以体循环淤血的表现为主。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">症状</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">1.消化道症状，胃肠道及肝淤血<span style="color: black;">导致</span>腹胀、食欲不振、恶心、呕吐等是右心衰最<span style="color: black;">平常</span>的症状。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">2.<span style="color: black;">呼气</span>困难。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">体征</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">1.水肿:其特征为<span style="color: black;">首要</span><span style="color: black;">显现</span>于身体最低垂的部位，为对<span style="color: black;">叫作</span>性可压陷性。胸腔积液<span style="color: black;">更加多</span>见于全心衰时。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">2.颈静脉征:颈静脉搏动<span style="color: black;">加强</span>、充盈、怒张，是右心衰时的<span style="color: black;">重点</span>体征，肝颈静脉反流征阳性是特征性体征。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">3.肝大:肝因淤血肿大常伴压痛，<span style="color: black;">连续</span>慢性右心衰可致心源性肝硬化，晚期可<span style="color: black;">显现</span>黄疸及<span style="color: black;">海量</span>腹水。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">4.心脏体征:可因右心室<span style="color: black;">明显</span>扩大而<span style="color: black;">显现</span>三尖瓣关闭不全的反流性杂音。</p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">既有左心衰的表现又有右心衰的表现。继发左心衰的右心衰<span style="color: black;">出现</span>后，<span style="color: black;">因为</span>右心排血量减少，<span style="color: black;">因此呢</span>阵发性<span style="color: black;">呼气</span>困难等肺淤血症状反而有所减轻。</p>

太棒了、厉害、为你打call、点赞、非常精彩等。 一看到楼主的气势，我就觉得楼主同在社区里灌水。 哈哈、笑死我了、太搞笑了吧等。
