Disfunción ventricular sistólica, un nuevo marcador de enfermedad coronaria en pacientes con estenosis aórtica sin infarto de miocardio previo

Identification of clinical factors associated with coronary artery disease could obviate the need for coronary angiography in selected patients with severe aortic stenosis. We studied 315 patients (68 [8] years) with severe aortic stenosis without previous infarction who underwent coronary angiography. In the univariate analysis, age (P=.001), dyslipidemia (P=.003), angina (P=.018), aortic gradient (P=.001) and reduced ejection fraction (P=.006) were predictors of coronary artery disease. After multivariate analysis, age (OR = 1.079, P=.01), ejection fraction < 40% (OR = 2.685, P=.02), angina (OR = 2.518, P=.04) and dyslipidemia (OR = 2.34, P=.008) were the factors independently associated with coronary artery disease. Left ventricular dysfunction correlated independently with the presence of coronary artery disease.
