INTRODUCTION: Up to 95% of the patients with heart transplantation (HT) suffer from arterial hypertension (AHT). The development of de novo AHT after HT has not been greatly studied. AIM: To identify the predictor variables for the development of de novo AHT after HT. MATERIALS AND METHODS: We retrospectively studied 253 patients with HT and who did not previously have AHT. We excluded cases of early mortality, re-transplants and combined transplants. We considered AHT as the constant need to take anti-hypertensive drugs to maintain blood pressure < 140/90 mmHg. We studied all the variables relating to recipient, donor, surgical procedure, immunosuppression and follow-up. The statistics used were the Student's t-test, chi-square statistic and a logistic regression analysis. RESULTS: Of the 253 patients, 109 (43%) developed AHT. The variables associated with more prevalent AHT were male recipient/donor, idiopathic dilated cardiomyopathy (IDCM) as cause of HT, having been a smoker as well as renal deterioration (RD) and hypercholesterolemia after HT. The multivariate analysis found smoking prior to the HT and hypercholesterolemia during follow-up as independent risk factors and urgent HT as a protective variable. CONCLUSIONS: AHT after HT is frequent. The variables associated in our population were smoking before HT, male recipient/donor, IDCM prior to HT and hypercholesterolemia and RD after HT.
