摘要
２１２例急性心肌梗塞中，２１例发生早期心肌再梗塞和梗塞延展，发生率为９．９％（２１／２１２），多发生在梗塞后２～８ｄ．高危因素有：各种部位的前壁心肌梗塞，梗塞后心绞痛，心功能Ｋｉｌｌｉｐ分级Ⅱ级以上，大、小便用力及活动增加等．早期心肌再梗塞和梗塞延展的心电图特征为：ＳＴ段再度抬高；Ｒ波丢失和进展性Ｑ波．
Among 212 patients with acute myocardial infarction, 21 cases suffered from early myocardial reinfarction and myocardial infarct extension, The incidence was 9.9%(21/212).It usually developed during the 2nd to the 8th day of the acute myocardial infarction.The high risk factors were as follows :the various portions of anterior wall myocardial infarction;post-infarct angina pectoris;above Ⅱ grade of cardiac functional capacity according to classification of Killip;the exertion on urination and defecation and increased physical activities, The electrocardiographic features of early myocardial reinfarction and infarct extension were as below : re-elevation of ST segment,loss of R wave and developing Q wave.
