Evaluation of physical activity’s effect before Myocardial Infarction on the function class of patients and prognosis after MI

Background: The incidence of MI is increasing in all societies, as in Iran, and coronary artery disease is the most common cause of death in Iran. Physical inactivity is the risk factor for MI and activity is a protective factor. Note that the length of hospitalization, function class EF, and required interventions for patients after MI, are the most important determinants of performance for these patients, the current study is performed to evaluate the effect of physical activity on patients with prior MI. Methods: Physical activity retrospectively by questionnaire were asked. Hospitalization period, interventions, function class and EF after MI by clinical and patient records extracted and completed during 3 months with data calls. Finally, the data using descriptive and inferential statistical analysis was performed. Results: Ejection fraction and mean duration of hospitalization in patients with activity showed a significant difference (P=0.001). There is a significant relationship between physical activity and readmission of patients after myocardial infarction (P=0.002) also between physical activity and function class (P=0.001). Conclusions: Physical activity reduces dyslipidemia, the need for hospitalization and readmission. Also reduces the need for intervention, especially the more aggressive interventions and 3-month mortality. Physical activity improve cardiac function (EF) and individual performance (lowering of function class) is in MI patient
