Abstract

Purpose: To evaluate prognostic value of heart rate in patients with acute myocardial infarction.

Patients and method: Our retrospective study included 105 patients with acute myocardial infarction. Patients were divided in two groups: I group were patients with adverse outcome (MACE (myocardial infarction, unstable angina, cardiovascular death, revascularisation, fatal/nonfatal cerebrovascular accident, aortic event) and heart failure requiring hospitalization) during one month after myocardial infarction and II group were patients without adverse outcome. We observed the presence of the following factors: heritage, heart rate at admission and its influence on one month outcome.

Results: 50 patients had STEMI and 55 NSTEMI, 65 were male. 54 patients had complications one month after myocardial infarction. There is no statistically significant difference in heritage between two groups (p=1,000; Fisher's Exact test). Average heart rate in I group was 44,50 per minute and in II group was 50,00 per minute. There was statistically significant difference between groups (p=0,008). Inquiring prognostic value of the heart rate one month after myocardial infarction we used univariate binary logistic regression: adjusted hazard ratio: 1.011; 95% confidence interval: 0,998-1,024; p= 0,098.

Conclusion: Lower heart rate is present in patients with adverse outcome one month after myocardial infarction, but it can not be used as a prognostic factor.
