Introduction:

Acute myocardial infarction is one of the primary causes of death in Cuba, and the world. Currently, around 20% to 30% of patients with coronary disease have renal failure.

Objective:

To determine the relationship between renal failure at the time of admission and the short-term mortality in patients with acute myocardial infarction.

Material and methods:

An analysis was made on a total of 284 consecutive patients with a diagnosis of acute myocardial infarction admitted into the Intensive Care Unit (ICU) of the “Dr. Miguel Enríquez” University Hospital between 1 January 2015 and 1 December 2016. The creatinine and the calculated glomerular filtration rate were determined, as well as the scores on the cardiovascular prognostic scales, at the time of admission. The predictive value of the renal function for short-term death was evaluated using logistic regression.

Results:

A total of 26 (9.2%) patients died in the ICU. The serum creatinine was higher and the glomerular filtration rates were lower (P < .001) in the patient group that died compared to the survivors. All the renal function variables and the cardiac prognostic scores were associated with mortality. A better discrimination was obtained with the renal function variables compared to the cardiovascular ones.

Conclusions:

The assessment of renal function using the serum creatinine level and the calculated glomerular filtration rate provide very useful and valuable information for the initial evaluation of patients with acute myocardial infarction.
