Objective: to describe the incidence and prognosis of cardiac allograft vasculopathy (CAV: cardiac allograft vasculopathy) according to the classification proposed by the International Society for Heart and Lung Transplantation (ISHLT). Methodology: cohort study of heart transplant recipients conducted between February 2003 and November 2011 with angiographic follow-up. The primary outcome was CAV according to the ISHLT. We used chi-square tests for categorical variables and Student t test for quantitative variables. Kaplan-Meier survival analysis was made. Results: 118 patients were included. 83.1% were male with a mean age of 46.4 IQR (38.4 to 55.6) years. The average follow-up was 5 + 4.7 years with 2.4 + 1.6 coronary angiograms / patient. The overall incidence of CAV was 23.7%. Grade 1 (mild) 11.9%, grade 2 (moderate) 7.6% and grade 3 (severe) 4.2%. The only factor with a modest association was pulmonary hypertension with RR 2.54 (1.1 to 6.1) p = 0.05. The mortality of patients according to the degree of vasculopathy was: mild 0%, grade 2 (moderate) 42% RR 2.59 CI 95% (1.14 to 5.9) p = 0.024; Grade 3 (severe) 72 % RR 4.44 95% CI (2.27 to 8.6) p <0.0005. Conclusions: the incidence of CAV was 23.7%. The only factor modestly related was pulmonary hypertension. The scale proposed by the ISHLT is associated in grades 2 and 3 (moderate and severe) with significant mortality.
