【摘要】：目的:本研究通过分别检测青海地区藏族、汉族冠心病患者(包括稳定型心绞痛患者、急性冠脉综合征患者)及正常对照组的心率减速力,比较青海地区藏族、汉族之间心率减速力有无统计学差异,藏族、汉族冠心病患者与健康对照组心率减速力有无统计学差异,评估其迷走神经张力,从而判断藏族、汉族高危猝死人群,及时予以干预措施。对象与方法:按照入选标准与排除标准,病例组随机抽取2015年10月-2016年10月我科收治的藏、汉族稳定型心绞痛(SAP)患者各30例、急性冠脉综合征(ACS)患者各30例,并选择同期在我院进行体检的藏、汉族健康者各30例作为对照组。所有患者均行24小时心电监护检查,测得心率减速力数值,并使用SPSS19.0进行统计学分析。结果:1、藏族对照组、藏族SAP组、藏族ACS组DC值水平均分别高于汉族对照组、汉族SAP组、汉族ACS组,差异有统计学意义(P0.05);2、藏族SAP组DC值水平低于藏族对照组、藏族ACS组DC值水平低于藏族对照组、藏族ACS组DC值水平低于藏族SAP组,差异均有统计学意义(P0.05);3、汉族SAP组DC值水平低于汉族对照组、汉族ACS组DC值水平低于汉族对照组、汉族ACS组DC值水平低于汉族SAP组,差异均有统计学意义(P0.05)。结论:1、藏族DC值水平高于汉族,提示其迷走神经张力相对较高,发生心脏性猝死(SCD)的可能性相对较低。2、藏、汉族冠心病(CHD)患者DC值水平低于对照组,提示藏、汉族CHD患者迷走神经张力减低,其心脏保护性作用减低,发生SCD的危险性增高。3、藏、汉族ACS患者DC值水平低于SAP患者,提示随着冠心病病变严重程度的增加,其迷走神经张力减低,发生心脏性猝死的危险性增高。
[Abstract]:Objective: the aim of this study was to compare the heart rate deceleration of Tibetan patients, Han patients with coronary heart disease (including stable angina pectoris, acute coronary syndrome) and normal control group in Qinghai area. Whether there is statistical difference in heart rate deceleration between Han nationality and Tibetan nationality, and whether there is statistical difference in heart rate deceleration between Tibetan and Han patients with coronary heart disease and healthy control group, to evaluate the vagus nerve tension, and to judge the high risk sudden death population of Tibetan and Han nationality. Participants and methods: according to the criteria of inclusion and exclusion, 30 patients with stable angina pectoris and 30 patients with stable angina pectoris of Han nationality were randomly selected from the patients in our department from October 2015 to October 2016. There were 30 patients with acute coronary syndrome (ACSS) and 30 patients with Han nationality as control group. All patients underwent 24 hours ECG monitoring, and the values of heart rate deceleration force were measured. Results the DC levels in the control group, the control group, the SAP group and the ACS group were higher than those in the Han control group, the Han SAP group, and the Han ACS group, respectively. The DC level of Tibetan SAP group was lower than that of Tibetan control group, the DC value of Tibetan ACS group was lower than that of Tibetan control group, and the DC level of Tibetan ACS group was lower than Tibetan SAP group. The DC level of Han SAP group was lower than that of Han nationality control group, the DC value of Han nationality ACS group was lower than Han nationality control group, and the DC value of Han nationality ACS group was lower than Han SAP group. Conclusion the level of DC at 1: 1 is higher than that of the Han nationality, suggesting that the vagus nerve tension is relatively high and the probability of sudden cardiac death SCD is relatively low. The DC level of the patients with CHD is lower than that of the control group. The results suggest that the vagus nerve tension is decreased, the cardiac protective effect is decreased, and the risk of SCD is increased. The DC level of ACS patients in Tibet and Han nationality is lower than that in SAP patients, suggesting that the severity of coronary heart disease increases with the increase of the severity of coronary heart disease. Its vagus nerve tone is decreased, the risk of sudden cardiac death is increased.
