ESTUDIO DE LA CARDIOPATÍA ISQUÉMICA EN PACIENTES MENORES DE 45 AÑOS / Study of coronary artery disease in patients under 45 years of age

Abstract

Introduction and objectives: Coronary artery disease is the main cause of death in the developed world, also affecting young people. This investigation aims at determining the characteristics of suchan illness in people under 45 years of age. Method: A retrospective study was carried out during a two year period in the provincial hospitals of Villa Clara province. Results: 84,0 percent of the patients were male, and 68,0 percent were between the ages of 40 and 45. The infarction of the inferior wall represented 56.0 percent, 31 patients (62,0 %) presented a positive ergometry, 44 patients (88,0 %)had a normal ejection fraction, 34 patients (68,0 %) suffered from alterations of the regional motility, 92,0 percent had normal ventricular diameters and 76,0 percent showed a normal pattern of relaxation of the left ventricle (p = 0,000). Only 7 patients (14,0 %) had normal arteries. In the 43 remaining patients, 46,5 % presented type C lesions, 60,5 percent had the right coronary as the one responsible for the infarction, 60,5 percent had only one vessel affected, and 88.4 percent had stenosis obstructing more than half the diameter of the artery. Conclusions: In the investigation there was a prevalence of male individuals, the group between 40 and 45 years of age, an inferior localization, alterations of the ergonometric test, a normal LVEF, alterations of the regional contractibility, normal ventricular diameter and relaxation pattern, and a positive coronariography with a predominant damage of one vessel, left coronary and type C lesions
