15例经选择已确诊为急性心肌梗塞的病人,在发病后7～70小时被放置Swan—Ganz漂浮监护导管。这组病人中,平均肺动脉压(MPAP)增高者12例(20～53mmHg),肺毛压(POWP)增高者12例(17～47mmHg),两者比较吻合。同时伴有平均中心静脉压(CVP)增高者9例(15～40mmHg),另有3例CVP及PCWP均低,分别为-4～2与3～5mmHg。根据血液动力与临床症状之间的对照分析,发现在12例PCWP增高的病人中仅6例临床表现有心衰症状,另6例则无明显表现,这部分病人,应视为亚临床型心衰,若
Fifteen patients who had been diagnosed with acute myocardial infarction were housed in a Swan-Ganz floating monitoring catheter 7 to 70 hours after onset. Among these patients, 12 cases (20-53 mmHg) and 12 cases (17-47 mmHg) had higher mean pulmonary artery pressure (MPAP), the two were more consistent. There were 9 cases (15-40 mmHg) with elevated mean central venous pressure (CVP), and 3 cases had low CVP and PCWP of -4-2 and 3-5 mmHg, respectively. According to the contrast analysis between hemo motility and clinical symptoms, only 6 of 12 patients with elevated PCWP showed clinical symptoms of heart failure and the other 6 patients showed no obvious symptoms. These patients should be regarded as subclinical heart Decline, if
