ABSTRACT
Objective:
To explore diagnostic value of nocturnal ST-T changes in 24h dynamic electrocardiogram (DCG)for coronary heart disease (CHD)and its clinical significance.Methods:
A total of 103 cases,who showed ST-T changes in 24h DCG,received selective coronary angiography (CAG).Among them,the 56 patients with in-termittent nighttime significant ST-T changes were regarded as research group,while the other 47 patients with per-sistent ST-T changes were treated as control group.CAG results were compared and analyzed between two groups.Results:
Compared with control group,there were significant rise in CAG positive rate (31.9% vs.67.9%),inci-dence rates of dyspnea and chest pain (27.7% vs.66.1%),hypertension (48.9% vs.71.4%),hyperlipidemia (31.9% vs.42.9%)and diabetes mellitus (17.0% vs.46.4%),percentages of lesions in left anterior descending artery (LAD,21.3% vs.57.1%),left circumflex coronary artery (LCX,14.8% vs.37.5%)and right coronary artery (RCA,12.8% vs.35.7%)in research group,P <0.05 or <0.01.Conclusion:
Nocturnal ST-T signifieantly changes in 24h DCG,it possesses more diagnostic value for CHD,which can be regarded as a more sensitive index diagnosing myocardial ischemia.
