Asociación de la hipertrofía ventricular izquierda con eventos cardiacos posteriores a intervencionismo coronario percutáneo. Association of left ventricular hypertrophy with cardiac events after percutaneous coronary intervention.

Abstract

Introduction: Left ventricular hypertrophy is not included in the prognostic models of cardiacevents after percutaneous coronary intervention.Objective To determine the association of left ventricular hypertrophy with the presenceof cardiac events during 4 years follow-up after percutaneous coronary intervention.Method 80 hypertensive patients without prior revascularization, undergoing successfulpercutaneous coronary intervention with bare-metal stents at the NationalCardiology and Cardiovascular Surgery Institute between December 2002 andApril 2004, were prospectively included. The demographic, clinical and angiographiccharacteristics were included in our database during the procedure.We made a 4 years follow-up.Results Restenosis (p<0.02) was more frequent in the group of hypertensive patientswith hypertrophy of both anterior and posterior left ventricle walls. Univariateregression analysis showed that left ventricular hypertrophy associates with ahigher restenosis incidence (OR 3.12; CI 95% 1.20-8.14).Conclusions Left ventricular hypertrophy is a risk marker of restenosis after percutaneouscoronary intervention. There was no association with any other cardiac eventduring the long follow-up of hypertensive patients.
