Mortalidad posterior a cirugía de revascularización miocárdica

Abstract

Factors related to mortality after coronary bypass have been identified. Among the factors directly associated with the patient, age, socioeconomic status, poor LVEF, a history of arterial hypertension, diabetes mellitus, and COPD have been reported. Socioeconomic status has not been extensively studied, but there are reports where low levels are associated with increased mortality. The same occurs with gender, in which most studies associate it with higher mortality. The number of compromised coronary vessels, the greater number of transfusions of blood components, a greater pump time and ischemia, as well as the presurgical or transoperative support with vasoactive or inotropic agents. Long-term mechanical ventilation or stay in the ICU, as well as the presurgical presence of acute or chronic kidney injury, are also associated with an increase in mortality. Factors such as low SvO2, infections or postsurgical events such as cerebral ischemic events or arrhythmias must also be considered.
