خلاصه انگلیسی

Introduction:Acute myocardial infarction ( AMI) is one of the most common causes of death of human beings in the world today. In our country, Iran, the coronary heart disease is the major cause of death, too. AMI can be classified in two groups: Q wave and non Q wave. In this survey, we attempted to study the lowering rate of left ventricular ejection fraction in these two groups of AMI . Materials and Methods: This study was done in prospective and descriptive – analytic manner in a 2.5 years period in Ardabil Bouali Hospital in CCU ward. All of the patients who had come with chest pain and the AMI diagnosis was established for them were entered in the study.The diagnosis of AMI was proved by taking history and serial electrocardiograms and checking serum cardiac enzymes .The data of patients were inserted in special forms and then analyzed with SPSS soft ware . Results:600 patients were studied in this survey that 443 patients (73.83%) were male and 157 patients (26.17%) were female. The average age of patients was 59.90 years while it was 58.37 years in men and 64.22 years in wemon . 308 cases (51.33%) of all of the patients had anterior AMI and 258 (43%) had inferior,and the rest had mixed anterior and inferior AMI . Also 514 (85.6%) of patients had Q wave and 86 (14.4%) of patients had non Q wave AMI. The mean of left ventricular ejection fraction in patients was 45.52 %, while it was 46.22% in patients with Q wave AMI and 41.35% in patients with non Q wave AMI. Conclusions: As was mentioned above: 1) The male to female ratio in our patients was 2.8 to 1 . 2.The mean age was significantly lower in men in comparement to women . 3 . The anterior AMI was more common than of inferior AMI in our study .
