The short-term survival following acute myocardial infarction: A prospective observational study

To investigate 28 days survival rate following first acute myocardial infarction (AMI) associated with the presence of classical risk factors and treatment modalities in Gorgan, north of Iran.

Our cohort including all patients hospitalized due to AMI from 2010 to 2013. Data were collected on demographic, prophylactic drugs and classical coronary risk factors. Data were analyzed using Kaplan-Meier and log rank tests. Cox proportional hazard model was built to estimate relative risk by taking into account other variables.

Median age of subjects was 58 and 64 for men and women, respectively; moreover, the occurrence of diabetes was 52.5 and 24.5 for them. A poorer outcome was detected in survival rate for women in the final model. Excess death occurrence in Fars or non- Persian ethnicity, and those who were not prescribed statin was detected in the adjusted model.

A better survival rate for those who were prescribed statin suggest that it could be beneficial in treatment modality and non-Persian ethnicities needed to be considered as a group of at risk for earlier screening programs. In spite of some other studies a poorer outcome following AMI for women was found even after taking into account age and comorbidity.
