Abstract
Background: This study aimed to investigate short-term survival (28 days) and to determine some predictive factors of short-term survival in patients with acute myocardial infarction(AMI).
Subject and Methods: This study was a historical cohort study that was conducted on 260 patients with AMI in Ganjavian Hospital a referral hospital in Dezful, Iran, 2018-2019. Life table and Kaplan Meier analyses were used for the assessment of short-term survival rate. Log-rank, Wilcoxon tests, and Cox multivariate regression were used to compare survival functions and determine the predictive factors of short-term survival.
Results: The mean age of the patients was 57.91 ± 10.76 years and 193 (74.23%) were male. The survival rate was 90% on the 28th day. In Cox regression, the risk of death in women was higher than in men (HR=1.82, 95% CI: 1.08-3.47). Also, the risk of death had a statistically significant association with diabetes status (HR=2.87,95% CI: 1.21-6.78), history of ACS (HR=3.03, CI95%: 1.32-6.92), EF<30 (HR=5.24, CI95%: 1.68-9.30), thrombolytic drugs (HR=1.84, CI95%: 1.10-3.57), arrhythmia (HR=6.98,95% CI: 2.31-21.08) and anterior MI (HR=1.67, CI95%: 1.27-2.79).
Conclusion: In the AMI patients, the 28-day survival rate was about 90%, which was the highest risk of death in the first 8 days after an AMI. The factors of sex, diabetes status, history of ACS, EF, thrombolytic drugs, arrhythmia, and location of AMI were related to the survival of patients. Therefore, timely and appropriate follow-up of treatment, especially in high-risk groups, plays an important role in increasing the patient survival with AMI.
