心血管疾病的癥狀有哪些

紫紺(Palpitation)是主觀(guān)感覺(jué)及客觀(guān)征象的綜合癥狀。主觀(guān)上患者感覺(jué)心臟跳動(dòng)快速、不整或搏動(dòng)有力?？陀^(guān)檢查可見(jiàn)心跳頻率過(guò)快、過(guò)緩或不齊，即有心率和心律的變化。

呼吸困難(dyspnea)也是主觀(guān)感覺(jué)和客觀(guān)征象的綜合表現。主觀(guān)上感覺(jué)呼吸費力，客觀(guān)上呼吸次數增多，動(dòng)作快而幅度加大。

胸部的各種器官都可以出現呼吸困難的癥狀。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.運動(dòng)性呼吸困難(exertionaldyspnea)：中國科學(xué)院腎病檢測研究所正常人在劇烈運動(dòng)時(shí)也有呼吸困難感覺(jué)，停止運動(dòng)后很快恢復。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)出現癥狀，而且恢復慢甚至于不恢復。

2.端坐呼吸(orthopnea)：患者表現不能平臥或不能長(cháng)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-25%)。

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

發(fā)生機制除上述的兩點(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):是最嚴重的一類(lèi)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。體內還原血紅蛋白(未經(jīng)氧飽和的血紅蛋白)絕對值超過(guò)5g%(6~7vol%的不飽和度)。

紫紺的機制為缺氧血，血紅蛋白過(guò)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(guò)多的未經(jīng)氧合的血液。見(jiàn)于有右到左分流的先天性心臟病，如法樂(lè )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。

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

2.周邊型紫紺：見(jiàn)于周?chē)魉俣冗^(guò)于緩慢，單位時(shí)間內組織攝取過(guò)多的血氧。周邊型紫紺在活動(dòng)時(shí)并無(wú)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(jiàn)的癥狀，是人體對于空間關(guān)系的定向感覺(jué)障礙或平衡感覺(jué)障礙，使患者自覺(jué)周?chē)拔锘蜃陨碓谛D及搖晃，眩暈發(fā)作時(shí)常伴有平衡失調、站立不穩及惡心、嘔吐、面色蒼白出汗、心動(dòng)過(guò)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，導致大腦皮質(zhì)一過(guò)性功能障礙，引起突然的、可逆的、短暫的意識喪失的一種臨床病征。在發(fā)生意識喪失前常伴有面色蒼白、惡心、嘔吐、頭暈、出汗等植物神經(jīng)功能紊亂現象。

最常見(jiàn)的引起暈厥的原因有：

1.反射性暈厥：最常見(jiàn)，約占各型暈厥總數的90%，大多數是通過(guò)血管迷走反射，導致心臟抑制和全身血管擴張，引起回心血流量降低，心輸出量降低而導致腦缺血、缺氧引起暈厥。它們多數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(jiàn)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(guò)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(jiàn)原因有：①心律失常：常見(jiàn)有完全性房室傳導阻滯、病態(tài)竇房結綜合征、陣發(fā)性室上性或室性心動(dòng)過(guò)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(jiàn)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致暈厥，常見(jiàn)于低血糖、一氧化碳中毒、呼衰時(shí)二氧化碳儲留等。

5.精神性暈厥：癔病。

疲勞

是各種心臟病常有的癥狀。當心臟病使血液循環(huán)不暢，新陳代謝廢物(主要是乳酸)即可積聚在組織內，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(méi)有特殊性，它與其它疾病所致的疲勞難以區分。

為什么人在高山上會(huì )感覺(jué)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(huà)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。

當人在離開(kāi)海平面或海拔甚高的地方

很容易感覺(jué)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

導致氧氣的供應減少. 當人在平地行動(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 )因為血液中氧氣的成份少而二氧化碳多;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

往往導致呼吸加速病情更嚴重. Yip
