【摘要】：目的:本研究通過分別檢測(cè)青海地區(qū)藏族、漢族冠心病患者(包括穩(wěn)定型心絞痛患者、急性冠脈綜合征患者)及正常對(duì)照組的心率減速力,比較青海地區(qū)藏族、漢族之間心率減速力有無統(tǒng)計(jì)學(xué)差異,藏族、漢族冠心病患者與健康對(duì)照組心率減速力有無統(tǒng)計(jì)學(xué)差異,評(píng)估其迷走神經(jīng)張力,從而判斷藏族、漢族高危猝死人群,及時(shí)予以干預(yù)措施。對(duì)象與方法:按照入選標(biāo)準(zhǔn)與排除標(biāo)準(zhǔn),病例組隨機(jī)抽取2015年10月-2016年10月我科收治的藏、漢族穩(wěn)定型心絞痛(SAP)患者各30例、急性冠脈綜合征(ACS)患者各30例,并選擇同期在我院進(jìn)行體檢的藏、漢族健康者各30例作為對(duì)照組。所有患者均行24小時(shí)心電監(jiān)護(hù)檢查,測(cè)得心率減速力數(shù)值,并使用SPSS19.0進(jìn)行統(tǒng)計(jì)學(xué)分析。結(jié)果:1、藏族對(duì)照組、藏族SAP組、藏族ACS組DC值水平均分別高于漢族對(duì)照組、漢族SAP組、漢族ACS組,差異有統(tǒng)計(jì)學(xué)意義(P0.05);2、藏族SAP組DC值水平低于藏族對(duì)照組、藏族ACS組DC值水平低于藏族對(duì)照組、藏族ACS組DC值水平低于藏族SAP組,差異均有統(tǒng)計(jì)學(xué)意義(P0.05);3、漢族SAP組DC值水平低于漢族對(duì)照組、漢族ACS組DC值水平低于漢族對(duì)照組、漢族ACS組DC值水平低于漢族SAP組,差異均有統(tǒng)計(jì)學(xué)意義(P0.05)。結(jié)論:1、藏族DC值水平高于漢族,提示其迷走神經(jīng)張力相對(duì)較高,發(fā)生心臟性猝死(SCD)的可能性相對(duì)較低。2、藏、漢族冠心病(CHD)患者DC值水平低于對(duì)照組,提示藏、漢族CHD患者迷走神經(jīng)張力減低,其心臟保護(hù)性作用減低,發(fā)生SCD的危險(xiǎn)性增高。3、藏、漢族ACS患者DC值水平低于SAP患者,提示隨著冠心病病變嚴(yán)重程度的增加,其迷走神經(jīng)張力減低,發(fā)生心臟性猝死的危險(xiǎn)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.
