心房梗塞比通常认为的要常见得多。其发生率各家报告不一,尸解证实的心房梗塞为1％～42％。近来多认为1942年 Cushing 等报告的17％与尸解病例的真正发生率相近(表1)。心肌梗塞患者中,包括存活者中总的发生率甚至可能更高。心房梗塞也可在没有心室梗塞情况下发生。两组48例尸解证实为心房梗塞患者中有10例不伴有心室梗塞。
Atrial infarction is much more common than usually thought. The incidence of different reports, autopsy confirmed atrial infarction of 1% to 42%. More recently, 17% of Cushing et al.’s reports in 1942 were similar to the true incidence of autopsy cases (Table 1). The overall incidence among myocardial infarction patients, including survivors, may even be higher. Atrial infarction can also occur without ventricular infarction. 48 cases of autopsy confirmed that 10 cases of atrial infarction in patients without ventricular infarction.
