| 目的：探讨老年急性冠脉综合征患者(ACS)患者入院时心电图QRS 波时限与左心功能的相关性。方法：选取396 例老年
ACS患者为研究对象，测定所有患者入院时的体表心电图的QRS波时限，按照QRS 时限将患者将患者分为Ⅰ组：60 ms≤ QRS
时限≤ 80 ms、Ⅱ组：80 ms＜QRS时限＜100 ms、Ⅲ组：QRS时限≥ 100 ms；检测各组患者相关心脏超声心功能指标，同时检测入院
时肌钙蛋白I(cTnI)、肌酸激酶同工酶(CK-MB)、血清B 型脑钠肽(BNP)；记录患者住院期间发生左心衰竭情况。结果：与Ⅰ组及Ⅱ
组比较，Ⅲ组的BNP 及cTnI 明显升高(P＜0.05)、LVEF 降低(P＜0.05)；血清BNP 与QRS 时限呈正相关(P＜0.05)，而LVEF 与
QRS 时限呈负相关(P＜0.05)；QRSw 时限延长是老年ACS 患者发生左心衰竭的独立危险因素(OR=1.214，P＜0.05)。结论：老年
ACS患者QRS 时限延长与左心功能下降密切相关，可能是老年ACS 患者发生左心衰竭的独立危险因素。 |

| Objective:To investigate the correlation of early electrocardiogram QRS duration and left heart function in elderly
patients with acute coronary syndrome (ACS).Methods:A total of 396 cases of elderly patients with ACS were selected as the research
subjects. Their body surface electrocardiogram QRS duration was detected when they were admitted in hospital. Then according to their
QRS duration, they were divided into three groups: groupsⅠ (60 ms ≤ QRS ≤ 80 ms), groupsⅡ (80 ms < QRS < 100 ms), groups Ⅲ
(QRS ≥ 100 ms). We detected the related echocardiographic heart function index of all patients, at the same time detected the levels of
troponin I (cTnI), creatine kinase isoenzyme (CK-MB), serum b-type brain natriuretic peptide (BNP), and recorded the left heart failure
occurrence during hospitalization.Results:Compared with groupⅠ and Ⅱ , the BNP and cTnI levels of group Ⅲ was obviously
increased (P < 0.05), but the LVEF was decreased (P<0.05). The QRS duration was positively correlated with serumBNP (P < 0.05), but
negatively correlated with LVEF (P< 0.05). The eventually QRSw duration was the independent risk factor for left heart failure of elderly
patients with ACS (OR = 1.214, P < 0.05).Conclusion:QRS duration extension was closely related to the fall in the left heart function,
and might be the independent risk factor for left heart failure in elderly patients with ACS. |
