Insights
Quitting smoking and avoiding complications like stroke and heart failure significantly improve long-term survival for acute myocardial infarction survivors. Occupation also plays a role in overall mortality risk.

Abstract:
754 cases of acute myocardial infarction survivors were followed up for 28 days to 14 years, the missing rate was 1.86%. The factors influencing long-term prognosis were analyzed. Single factor analysis revealed sex, occupation, age, amount of cigarette smoked, history of stroke, and COPD, complications of heart failure, and arrhythmia, stroke and COPD, heart rate higher than 110/min, lung rales, frequency of infarction, quit smoking after infarction exerted significant influence on over all and cardiac death rate. Multiple factors Cox model analysis revealed quit smoking, complications of stroke heart failure, arrhythmia and occupation were the independent predicting factors for over-all causes of death. Frequency of myocardial infarction, quit smoking, amount of cigarette smoked, occupation, stroke were the independent prognostic factors of cardiac death.
