The Effect of Admission Creatinine Levels on One-Year Mortality in Acute Myocardial Infarction

Abstract EN

Background.

We have known that patients with renal insufficiency (creatinine level) have increased mortality for coronary artery disease.

In this study, the relationship between admission creatinine level and one year mortality are evaluated in patients with acute myocardial infarction (AMI).

Method.

160 AMI patients (127 men and 33 women with a mean age of 59 ± 13) were enrolled in the study.

Serum creatinine levels were measured within 12 hours of AMI.

The patients were divided into two groups according to admission serum creatinine level.

(1) elevated group (serum creatinine > 1.3 mg/dL) and (2) normal group (≤1.3 mg/dL).

One year mortality rates were evaluated.

Results.

Elevated serum creatinine is observed in the 27 patients (16.9%).

The mean creatinine level is 1.78 ± 7 mg/dL in the elevated group and 0.9 ± 0.18 mg/dL in the normal group (P<0.0001).

The mortality rate of the elevated group (n=7, 25.9%) is higher than that of the normal group (n=9, 6.8%).

A significant increase in one year mortality is also observed (P=002) 60.

Conclusion.

The mildly elevated admission serum creatinine levels are markedly increased to one year mortality in patients with AMI.
