Creatinine, potassium and glycemia values as predictors of adverse events in acute coronary syndrome

Abstract

Introduction: In recent years, the definition of acute coronary syndrome has encompassed the different forms of presentation of acute ischemic heart disease. Despite the current therapeutic possibilities, it still presents a high morbidity and mortality and there are no laboratory tools to suspect complications early.
Objective: To determine the value of the changes in the concentration of creatinine, potassium and glycemia as predictors of adverse events of acute coronary syndrome in patients admitted to Hospital Universitario Manuel Ascunce Domenech in the period from October 2017 to October 2018.
Methods: A analytical cohort study. The sample consisted of 124 patients. A form was made where the data were collected from the medical records, the variables were: age groups, sex, skin color, diagnosis, adverse event, creatinine, potassium and glycemia.
Results: The age group over 60 years old, male sex and white skin color predominated. The main adverse events were arrhythmias and left ventricular dysfunction. Elevated creatinine was associated with left ventricular dysfunction with heart failure and acute pulmonary edema, hyperkalemia was associated with potentially fatal arrhythmias that degenerated into asystole arrest and death. Hypokalemia was associated with arrhythmias and hyperglycemia with the recurrence of the ischemic episode.
Conclusions: All the patients with normal values of creatinine, potassium and glycemia without complications and their usefulness as predictors of adverse events of acute coronary syndrome was demonstrated.
