Abstract:ObjectiveTo explore foreboding inducement and clinical features of patients with first and recurrent acute myocardial infarction.MethodsOne hundred and forty-five patients with acute myocardial infarction who conformed to the diagnostic criteria of International Congress of Cardiology and World Health Organization (WHO) were enrolled.Patients were divided into first acute myocardial infarction (primary group) and recurrent acute myocardial infarction (recurrence group).The foreboding inducement and clinical features were analyzed.ResultsIncidence rate of anterior infarction in primary group was higher than that in recurrence group (62.03%,59.64%,χ2=0.21,P<0.01).Incidence rate of inferoposterior myocardial infarction in primary group (37.97%) was lower than that in recurrence group (40.50%),but the difference was not significant (χ2=8.65,P>0.05).The proportions of family history (32.43%) and anxiety-depression emotion (51.35%) in recurrence group were obviously bigger than those in primary group (16.61%,20.37%,χ2=6.56,3.81;P<0.05),but the ratio of smoking in recurrence group (29.73%) was lower than that in primary group (51.58%,χ2=3.88,P<0.05).The incidence rates of heart failure (43.24%),malignant arrhythmia (27.03%) and death (18.92%) in recurrence group were larger than those in primary group (20.37%,17.95%,7.40%),there were significant differences between the two groups (χ2=3.81,5.79,18.69;P<0.05).Meanwhile,the incidence rates of malignant arrhythmia (42.88%),death (21.43%) in ex-situ myocardial infarction patients were significant higher than those in in-situ myocardial infarction patients (13.04%,17.39%,χ2=5.88,4.50;P<0.05) in recurrence group.ConclusionsThe proportions of family history and anxiety-depression emotion in recurrence group are obviously higher than those in primary group.The incidence rates of heart failure,malignant arrhythmia and death in recurrence group are significant.The incidence rates of malignant arrhythmia and death in exsitu myocardial infarction patients are more higher than those in in-situ myocardial infarction patients in recurrence group.
