A comparative study of 7-days mortality rate in patients with Q wave and non-Q wave myocardial infarction in Ardabil Bouali Hospital

Introduction: Today, coronary heart disease, especially acute myocardial infarction(AMI ) is one of the most common causes of death in human beings. In electrocardiographic basis, there are two forms of AMI : Q wave and non-Q wave. The rate of prevalence, complications and the mortality of these two kinds are different. The aim of this survey, was to study the prevalence and first 7-days mortality rate of these two kinds of AMI. Methods and materials: This study was done in descriptive – analytic and prospective method in 600 patients with AMI admitted in Ardabil Bouali Hospital, and the informations were collected in special forms and were analyzed by the statistical soft wares. Findings: From the 600 studied patients, 438 persons (73%) were male and 162 persons (27%) were female.Also, 514 persons (85.67%) had Q wave AMI and 86 persons (14.33%) had non-Q wave AMI. From patients with Q wave AMI , 73.74% (379 patients) were male and 26.26% (135 patients) were female. 59 patients with non-Q wave AMI (68.60%) were men and 27 persons (31.40%) were women. From all of the patients, 34 persons (5.66%) died in first 7 days of admission, that 29 patients had Q wave(5.64% of Q wave AMI patients) and 5 patients had non-Q wave AMI(5.81% of non Q wave AMI patients). Conclusion: As mentioned above, from all of the patients with AMI, 14.33% had non-Q wave AMI, that it seems very lower than from the standard sources (about 33%).The ratio of female patients with Q wave AMI to total female patients with AMI was 83.33%, while this ratio in non-Q wave AMI group was 16.67%. These figuers in male were 86.53% with Q wave and 13.44% in non-Q wave AMI. And it is clear that there is no prominent differences in the prevalence rate of Q wave and non-Q wave MI in men and women. Also the first 7-days mortality of patients was 5.66% (5.48% in men and 6.17% in women), and no clear difference was between men and women. In other words, the prevalence rate of Q wave and non-Q wave AMI and the mortalities of them in men and women had no significant differences in our study
