摘要
Objective: To discuss the related risk factors of sudden death in dilated cardiomyopathy (DCM)patients. Methods: A retrospective survey of DCM patients was conducted, all patients were chosen at random from Xi’an city and 8 adjacent counties. One hundred and fifty patients were reinvestigated after 3.1±1.5 years. Binary multivariate logistic regression analyses and one way analysis of variance (ANOVA) were used to identify risk factors of the sudden death in DCM patients. Results: Risk factors of sudden death in 150 DCM patients were frequently ventricular premature beats (OR=11.617), paroxysmal ventricular tachycardia (OR=6.305), hypertension (OR=5.689), EF (OR=0.977). The serum sodium concentration (P=0.023) and left ventricular diastolic dimension (LVDD)(P=0.039) were significant difference between the sudden death group and the survival group in one way ANOVA, LVDD was not a risk factor in multivariate analysis controlling for possible confounding. Conclusion: The present study identified some risk factors of sudden death in DCM patients, including frequently ventricular premature beats, paroxysmal ventricular tachycardia, hypertension and low EF value.
