目的 :探讨餐后心绞痛临床特征及心率变异性 (HRV)与病情的关系。方法 :对 31例餐后心绞痛 (餐后组 )与 35例无餐后心绞痛的劳力型心绞痛 (劳力组 )的临床特点进行比较 ,同时对餐后组、劳力组与年龄、性别相当的35例健康者 (健康组 )的 HRV分别进行比较。结果 :餐后组的中老年、男性、心肌梗死、自发性心绞痛、卧位性心绞痛、左室扩大、左室射血分数 (L VEF) <5 0 %的比例均显著高于劳力组 (P<0 .0 5～ 0 .0 1) ;餐后组与劳力组的 HRV均低于健康组 (P<0 .0 1) ;餐后组 HRV又明显低于劳力组 (P<0 .0 1)。结论 :餐后心绞痛病情严重 ,HRV明显降低与病情严重度及 L VEF、心功能下降相关。提示 :餐后心绞痛是冠心病心绞痛的一种特殊的严重类型 ,HRV有助于预测冠心病心绞痛的危险预后
Objective: To investigate the relationship between clinical features and heart rate variability (HRV) and the severity of postprandial angina pectoris. Methods: The clinical characteristics of 31 patients with postprandial angina pectoris (postprandial group) and 35 patients with labor-type angina pectoris without labor (labor group) were compared. Meanwhile, 35 patients with postprandial labor group Healthy people (healthy group) HRV were compared. Results: The proportion of middle-aged and elderly patients with myocardial infarction, spontaneous angina pectoris, recumbent angina, left ventricular enlargement and left ventricular ejection fraction (L VEF) <50% in postprandial group were significantly higher than those in labor group (P <0.01). The HRV of postprandial group and labor group were lower than that of healthy group (P <0.01). HRV of postprandial group was significantly lower than that of labor group (P <0. 0) 1). Conclusions: The postprandial angina pectoris is serious and the HRV is significantly decreased with the severity of the disease and LVEF and cardiac function decline. Tip: Postprandial angina pectoris is a special type of coronary heart disease, HRV helps predict the prognosis of angina pectoris
