【摘要】：目的分析静息心率(RHR)与冠心病患者冠状动脉病变和左心室功能的相关性,做好冠心病二级预防。方法收集2016年1月至2017年8月于广州军区总医院心血管内科住院经冠状动脉造影或冠脉CTA检查明确诊断为冠心病的患者共239例,收集入选患者的一般临床资料及冠脉病变程度和左心室功能的指标,按照患者RHR控制水平将患者分为4组:A组(RHR60次/min,n=32)、B组(RHR:60~69次/min,n=60)、C组(RHR:70~79次/min,n=68)、D组(RHR≥80次/min,n=79),比较各组患者冠状动脉病变和左心室功能的差异,分析RHR与冠脉病变和左室功能的相关性,并利用等级Logistic回归分析探讨RHR、左心室各指标与冠脉病变程度的关系。结果 A、B、C、D四组患者冠脉病变程度的差异具有统计学意义(P0.05),四组患者的LVDs、LVDd、LAs、EF的差异具有统计学意义(P0.05),而LAd的比较则无统计学意义(P0.05)。Logistic回归分析显示:吸烟、糖尿病、EF、LVDs等各项指标与冠脉病变程度相关(P0.05)。结论 RHR可影响冠心病患者的冠脉病变程度和左室功能,控制好RHR有益于冠心病患者的病情预后。
[Abstract]:Objective to analyze the relationship between resting heart rate (RHR) and coronary artery disease and left ventricular function in patients with coronary heart disease (CHD). Methods from January 2016 to August 2017, 239 cases of coronary artery disease (CHD) were diagnosed by coronary angiography or coronary CTA in Department of Cardiovascular Medicine, Guangzhou military region General Hospital. To collect the general clinical data of the patients, the degree of coronary artery lesion and the indexes of left ventricular function, According to the control level of RHR, the patients were divided into 4 groups: group A: RHR60 / min, group B: RHR6069 / RHR6069, group C: RHR7079, group D > 80 / min / 79, to compare the difference between coronary artery disease and left ventricular function in each group, and to analyze the correlation between RHR and coronary artery disease and left ventricular function, and to analyze the relationship between RHR and coronary artery disease and left ventricular function. The relationship between RHRand left ventricular indexes and severity of coronary artery lesion was studied by logistic regression analysis. Results there were significant differences in the severity of coronary artery lesions among the four groups (P 0.05, P 0.05). The differences of LVDsl, LVDdU, LAs1 EF in the four groups were statistically significant (P 0.05), but the comparison of lad was not statistically significant (P 0.05). Logistic regression analysis showed that: smoking. The indexes of EFD LVDs were correlated with the severity of coronary artery lesion (P 0.05). Conclusion RHR can affect the degree of coronary artery disease and left ventricular function in patients with coronary heart disease, and control RHR is beneficial to the prognosis of patients with coronary heart disease.
