A total of 130 anginal patients were examined within 3 months after the onset of anginal attacks. Angina was stable (SA) in 100 patients and unstable (UA) in 30. There were no differences between SA and UA patients in terms of the degree and spread of coronary arterial stenoses. Signs of coronary arterial spasm were detected in 27 (20.8%) of 130 patients, being more frequent in UA (53%), as compared to SA (11%; p less than 0.001). Acute myocardial ischemia produced groups of ventricular extrasystoles more frequently than it did isolated extrasystoles in patients with recent angina (78.6% vs. 16.7%; p less than 0.001). Groups of ventricular extrasystoles were recorded more frequently in UA patients, as compared to SA ones (23.3% vs. 7%; p less than 0.05).
共有130名心绞痛患者在心绞痛发作后的3个月内接受了检查。其中100例患者为稳定型心绞痛（SA），30例为不稳定型心绞痛（UA）。SA和UA患者在冠状动脉狭窄的程度和范围方面没有差异。在130例患者中，有27例（20.8%）检测到冠状动脉痉挛迹象，与SA患者（11%；p<0.001）相比，在UA患者中更常见（53%）。近期心绞痛患者中，急性心肌缺血导致室性早搏群的频率高于孤立性早搏（78.6%对16.7%；p<0.001）。与SA患者相比，UA患者中室性早搏群的记录更为频繁（23.3%对7%；p<0.05）。
