本研究使用的数据资料来源于Framingham心脏研究中心。Q波型心肌梗塞(Q-wave MI)患者在1年后的静息心电图(ECG)检查中,可从ECG的变化获得重要的预后信息。例如:某份ECG检查显示有其它异常改变而缺乏Q波者,意味着其预后不良,这种ECG表现以女性患者多见,故作者认为,这点可能有助于解释在心肌梗塞(MI)后早期死亡率中女性高于男性的临床现象。 1948年Framingham的5209例登记患者中,Q-waveMI存活者251例,1年后静息ECG检查;无异常者31例(12.4%);无持续性Q波而有其他异常者37例(14.7%):有持续性Q波而无其他异常者108例(43.0%);有持续性Q波伴其他异常
The data used in this study were obtained from the Framingham Heart Research Center. Patients with Q-wave MI (myocardial infarction) (Q-wave MI) in 1 year after resting electrocardiogram (ECG) examination, changes in ECG can be obtained from the important prognostic information. For example, an ECG examination showing other abnormal changes without a Q-wave implies poor prognosis, which is more common in women than in women, and the authors believe this may help explain the role of myocardial infarction (MI) Women in early post-mortem rates were clinically more aggressive than men. Of the 5209 registered patients in Framingham in 1948, 251 were Q-wave MI survivors, with resting ECG after 1 year; 31 without abnormalities (12.4%); 37 with other abnormalities without persistent Q wave (14.7 %): Persistent Q wave without other abnormalities in 108 cases (43.0%); with persistent Q wave with other abnormalities
