    ABSTRACT: To evaluate the safety and efficacy of ezetimibe in a sample of transplanted cardiac patients. We undertook a descriptive retrospective observational study of 19 transplanted cardiac patients in whom treatment with ezetimibe was initiated at doses of 10 mg/d between 2004 and 2006, assessing tolerability and changes in lipid levels (total cholesterol and triglycerides), doses of immunosuppressive drugs, and the hepatic profile after 12 months of treatment. There was no effect on the doses required of any immunosuppressive drugs. We observed a reduction in cholesterol levels, with a normal distribution (mean +/- standard deviation 26.84 +/- 14 mg/dL) among patients with ezetimibe addition, despite no change in the statin doses. There were no changes in the levels of triglycerides, transaminases, or bilirubin, and no cases of rhabdomyolysis or myalgia. All patients continued to take the drug after 1 year of treatment. In our sample, the administration of ezetimibe to transplanted cardiac patients for 1 year was associated with a reduction in cholesterol levels by 26.8%. No substantial changes in the doses of immunosuppressive drugs could be attributed to the use of ezetimibe. Tolerance was good, with no need for drug withdrawal in any case.

    ABSTRACT: Diabetes mellitus is one of the main metabolic complications after heart transplantation. The aims of our study were to determine the incidence and factors that determine the appearance of posttransplantation diabetes mellitus (PTDM) and its prognostic value. We performed a retrospective study of all heart transplant recipients in our hospital from January 1993 to December 2005, including 116 patients with prolonged monitoring with 59-month median follow-up. We divided the patients into two groups, according to whether they had de novo diabetes (group 1) or no diabetes (group 2). Patients with PTDM were significantly older, with a median difference (MD) of 5.4 years (95% confidence interval [CI], 1.53-9.28) and a greater body mass index (MD, 3.37 kg/m(2); 95% CI, 1.68-5.06). Moreover, a greater percentage of patients in group 1 had ischemia compared to other etiologies. However, no significant differences were observed regarding other cardiovascular risk factors. PTDM was associated with a greater incidence of posttransplant hypertension (51.6% in group 1 vs 48.4% in group 2, P = .08) and posttransplant renal failure (59.5% in group 1 vs 40.5% in group 2, P = .001). However, no differences were observed in overall survival. Age, overweight, and ischemic origin of cardiopathy were the main risk factors for the development of PTDM in our population. Although no differences were observed in survival rates, PTDM was associated with a greater incidence of hypertension and renal insufficiency, which may have long-term influences on patient survival.

    ABSTRACT: Invasive assessment of pulmonary artery pressure (PAP), via right heart catheterization, is part of the usual protocol prior to heart transplantation. Echocardiography is considered a valuable technique to evaluate PAP. We sought to determine the reliability of measurements of PAP via a noninvasive technique, echocardiography, in relation to the estimated PAP via right catheterization. We also determined its safety when invasive procedures are restricted to just patients with pulmonary hypertension (PHT) according to echocardiographic parameters. We performed a retrospective study of 67 right catheterizations performed in our hospital, within the heart transplant study protocol, from January 2000 to December 2006. PAP parameters were estimated by echocardiography and right catheterization. Hemodynamically, 57.1% of the patients had severe PHT (more than 45 mm Hg mean PAP); 13.2% moderate PHT (between 35 and 45 mm Hg mean PAP); 12.1% had mild PHT (between 25 and 35 mm Hg mean PAP); and 17.6% of patients showed no PHT. Pearson correlation index with systolic PAP (estimated via echocardiography) and mean PAP (calculated via invasive method) was 0.69 (P < .001). PHT was considered significant when systolic PAP estimated via echocardiography reached more than 40 mm Hg and mean PAP estimated via right catheterization reached more than 35 mm Hg, the value from which the vasodilator test was carried out. According to these parameters, echocardiography showed a sensitivity of 89% to diagnose significant PHT and 46% specificity, with positive and negative predictive values of 70% and 76%, respectively.

    ABSTRACT: Invasive estimation of pulmonary pressure is part of the usual protocol prior to heart transplantation. The aim of this study was to compare the results of 2 different vasodilators, nitric oxide (NO) and prostacyclin, in an acute vasodilator test (AVT) for patients with pulmonary venous hypertension. From January 2000 to December 2006, 94 right-sided heart catheterizations were performed in our center within pretransplantation evaluations. AVT was performed if the mean pulmonary artery pressure (mPAP) >35 mm Hg or if the pulmonary vascular resistance (PVR) was >4 Wood units (WU). Epoprostenol was administered to 40 patients, NO to 6 patients, and both agents to 8 patients. A significant decrease in both mPAP and PVR was shown with maximum doses of epoprostenol, with an average variation of 8.96 mm Hg in mPAP (P < .001) and 3.26 WU in PVR (P < .001). An increased cardiac output (CO) was observed with epoprostenol, with a mean difference of 1.9 L/min (P < .001) at maximum compared with baseline doses. A tendency for the mPAP and PVR to decrease was also observed with maximum NO doses, with mean decreases of mPAP and PVR of 5.62 mm Hg and 1.14 WU, respectively. A tendency for CO to decrease was observed with NO (0.75 L/min; P = .039). In our experience, NO is the best drug for AVT due to its pulmonary tree selectivity. A study with epoprostenol was complementary; both drugs can be used in these patients prior to heart transplantation.

    ABSTRACT: A recent study proposed a risk index (McCluskey index) based on 7 parameters to identify the transfusion needs of patients during surgery and in the first 24 hours postoperation. The initial objective of our study was to validate this predictor for blood product transfusions. We undertook a retrospective, observational study of all liver transplant patients between January 1, 2005 and December 31, 2006. The following variables were recorded for each patient: age, gender, patient comorbidity, biochemical values prior to liver transplantation, and transfusion needs. Comparing the transfusion needs of those patients with scores <5 with those of scores >/=5, we observed significant differences in terms of the use of red blood cell concentrates, plasma, and platelets, both during the first 24 hours and in the total number. The index sensitivity was 80% (95% confidence interval [CI]: 71.23-88.76), with a specificity of 84.21% (95% CI: 67.81-100), where the positive predictive value was 95.52% (95% CI: 90.57-100.4) and the negative predictive value was 50% (95% CI: 32.67-67.32). The McCluskey index showed sufficient sensitivity and specificity to predict which patients will require a massive transfusion.
