心血管疾病的癥狀有哪些

紫紺(Palpitation)是主觀感覺及客觀征象的綜合癥狀。主觀上患者感覺心臟跳動(dòng)快速、不整或搏動(dòng)有力?？陀^檢查可見心跳頻率過快、過緩或不齊，即有心率和心律的變化。

呼吸困難(dyspnea)也是主觀感覺和客觀征象的綜合表現(xiàn)。主觀上感覺呼吸費(fèi)力，客觀上呼吸次數(shù)增多，動(dòng)作快而幅度加大。

胸部的各種器官都可以出現(xiàn)呼吸困難的癥狀。如腦梗塞，肺炎，急性氣胸，氣道堵塞，胸壁肌肉炎癥，肋骨骨折等，甚至皮膚帶狀皰疹的疾病疼痛也可以導(dǎo)致呼吸困難。心臟病的呼吸困難多為漸進(jìn)性，逐步加重。

1.運(yùn)動(dòng)性呼吸困難(exertionaldyspnea)：中國(guó)科學(xué)院腎病檢測(cè)研究所正常人在劇烈運(yùn)動(dòng)時(shí)也有呼吸困難感覺，停止運(yùn)動(dòng)后很快恢復(fù)。心臟病患者在常人不會(huì)發(fā)生呼吸困難的活動(dòng)量時(shí)出現(xiàn)癥狀，而且恢復(fù)慢甚至于不恢復(fù)。

2.端坐呼吸(orthopnea)：患者表現(xiàn)不能平臥或不能長(zhǎng)時(shí)間地平臥，斜靠位甚至于端坐，雙下肢垂于床邊。不能平臥的機(jī)制是

①平臥時(shí)下肢和腹腔的血液失去地心引力作用，返回心臟增多，加重了心臟的工作負(fù)荷;

②平臥時(shí)肺活量降低。正常人平臥位的肺活量有輕度降低(-5%)，病人因肺淤血等因素，肺活量下降更多(可達(dá)-25%)。

3.陣發(fā)性夜間呼吸困難(paroxysmalnocturnaldyspnea)：又稱為“心源性哮喘”，以區(qū)別于肺臟疾病引起的哮喘。

發(fā)生機(jī)制除上述的兩點(diǎn)外，入睡后呼吸中樞敏感性降低，肺臟淤血到一定程度造成明顯的缺氧，使患者從睡夢(mèng)中驚醒已感到呼吸極度困難。病人立即從臥位改變?yōu)樽?，甚至站立位，癥狀才能逐漸緩解。

4.急性肺水腫(acutepulmonaryedema):是最嚴(yán)重的一類型呼吸困難，可以影響患者生命，需要急癥急癥處理。病人表現(xiàn)為極度呼吸困難，端坐呼吸，明顯的缺氧，不斷咳粉紅色泡沫樣痰。

紫紺

紫紺(cyanosis)是指粘膜和皮膚呈青紫色。體內(nèi)還原血紅蛋白(未經(jīng)氧飽和的血紅蛋白)絕對(duì)值超過5g%(6~7vol%的不飽和度)。

紫紺的機(jī)制為缺氧血，血紅蛋白過多，及血液淤滯。有中心型及周邊型兩種。

1.中心型：指發(fā)生于心臟及肺臟器官水平的紫紺。動(dòng)脈血因氧飽和不足或混有過多的未經(jīng)氧合的血液。見于有右到左分流的先天性心臟病，如法樂氏四聯(lián)癥、艾森曼格氏綜合癥等，及因肺動(dòng)脈壓升高致間隔缺損晚發(fā)右至左分流。肺臟病變致血液氧合障礙也是中心型紫紺的重要原因。在重度心力衰竭時(shí)，肺臟淤血影響氧合產(chǎn)生中心型紫紺。

中心型紫在運(yùn)動(dòng)時(shí)加重。長(zhǎng)期血氧不飽和可以出現(xiàn)血紅蛋白增多及杵狀指趾。

2.周邊型紫紺：見于周圍血流速度過于緩慢，單位時(shí)間內(nèi)組織攝取過多的血氧。周邊型紫紺在活動(dòng)時(shí)并無明顯加重。

心力衰竭時(shí)血流緩慢，周邊組織攝氧多。因此其紫紺綜合了兩種形式。

眩暈

眩暈(vertigo)是臨床上常見的癥狀，是人體對(duì)于空間關(guān)系的定向感覺障礙或平衡感覺障礙，使患者自覺周圍景物或自身在旋轉(zhuǎn)及搖晃，眩暈發(fā)作時(shí)常伴有平衡失調(diào)、站立不穩(wěn)及惡心、嘔吐、面色蒼白出汗、心動(dòng)過緩、血壓下降等植物神經(jīng)功能紊亂癥狀。

暈厥

暈厥(syncope)是由于一時(shí)性廣泛的腦缺血、缺氧，導(dǎo)致大腦皮質(zhì)一過性功能障礙，引起突然的、可逆的、短暫的意識(shí)喪失的一種臨床病征。在發(fā)生意識(shí)喪失前常伴有面色蒼白、惡心、嘔吐、頭暈、出汗等植物神經(jīng)功能紊亂現(xiàn)象。

最常見的引起暈厥的原因有：

1.反射性暈厥：最常見，約占各型暈厥總數(shù)的90%，大多數(shù)是通過血管迷走反射，導(dǎo)致心臟抑制和全身血管擴(kuò)張，引起回心血流量降低，心輸出量降低而導(dǎo)致腦缺血、缺氧引起暈厥。它們多數(shù)系壓力感受器反射弧傳入通路上的功能障礙所致。臨床上常見有單純性暈厥(血管減壓性暈厥)、體位性低血壓(直立性低血壓)暈厥、頸動(dòng)脈竇過敏性暈厥、咳嗽性暈厥、排尿性暈厥、吞咽性暈厥等。

2.心源性暈厥：因心臟輸出量突然減少而發(fā)生的暈厥。常見原因有：①心律失常：常見有完全性房室傳導(dǎo)阻滯、病態(tài)竇房結(jié)綜合征、陣發(fā)性室上性或室性心動(dòng)過速、心室撲動(dòng)、心室纖顫等。②心臟搏出障礙：急性心包壓塞、急性心肌梗塞與心絞痛、左房粘液瘤、主動(dòng)脈或頸動(dòng)脈高度狹窄等。

3.腦源性暈厥：因腦部血循環(huán)障礙或腦神經(jīng)組織病變所致的暈厥，臨床上常見于高血壓腦病、椎基底動(dòng)脈供血不全、頸椎病、顱腦損傷后等。

4.代謝性暈厥：由于血液成份異常導(dǎo)致暈厥，常見于低血糖、一氧化碳中毒、呼衰時(shí)二氧化碳儲(chǔ)留等。

5.精神性暈厥：癔病。

疲勞

是各種心臟病常有的癥狀。當(dāng)心臟病使血液循環(huán)不暢，新陳代謝廢物(主要是乳酸)即可積聚在組織內(nèi)，刺激神經(jīng)末稍，令人產(chǎn)生疲勞感。疲勞可輕可重，輕的可不在意，重的可妨礙工作。但心臟病疲勞沒有特殊性，它與其它疾病所致的疲勞難以區(qū)分。

為什么人在高山上會(huì)感覺呼吸困難

高山上的大氣層壓力會(huì)比水平面低，即是每立方單位的空氣的含氧量低，氧氣分子少了，人呼吸的"力度"一樣的話便吸少了氧氣，因此感到"暈眩"或者需要"加力"呼吸才能吸入足夠的氧氣分子。

當(dāng)人在離開海平面或海拔甚高的地方

很容易感覺到呼吸困難或氣喘的癥候(Dyspnea or shortness of breath);究其緣因是由于高地方的空氣薄弱

導(dǎo)致氧氣的供應(yīng)減少. 當(dāng)人在平地行動(dòng)的時(shí)候

其身體產(chǎn)生多量二氧化碳和使用大量氧氣;在腦部的呼吸中心就會(huì)因?yàn)檠褐醒鯕獾某煞萆俣趸级?而加速呼吸的頻率

假使人患上肺病

其心臟和肺部的功能不正常

往往導(dǎo)致呼吸加速病情更嚴(yán)重. Yip
