Prognostic Value of Blood Panel Parameters in Patients With Dilated Cardiomyopathy and Advanced Heart Failure.

BACKGROUND: Patients with dilated cardiomyopathy (DCM) and left ventricular dysfunction have a varied clinical course, not only dependent on left ventricular ejection fraction (LVEF) and symptoms. Finding prognostic markers for stratification in these 2 conditions is a critical area of research. Our aim was determine the prognostic value of blood panel basic parameters. METHODS: We analyzed all patients with idiopathic or familial DCM and LVEF <30% coming to our heart failure unit for evaluation for non-urgent heart transplant during the period of 2009 to 2011. With 5 years of follow-up data, we could study the prognostic value of blood panel parameters. Moreover, we determined the combination of platelet count and neutrophil to lymphocyte ratio score from the BIOSTAT-CHF study. RESULTS: Eighty-seven patients were included in the study. After 5 years follow-up, 49 patients (57%) remain alive (group A) and 38 (43%) either died or needed a heart transplant. There were no differences between groups with regard to age or sex. Patients with good progress showed a lower red cell distribution width (RDW), a higher lymphocyte count, and a lower neutrophil/lymphocyte ratio in the initial blood panel. An RDW ≥15% was associated with long-term mortality or heart transplant. CONCLUSION: A basic blood panel could be a useful tool in assessing patients with heart failure. Larger studies are necessary to confirm our findings. A multimarker strategy could also be useful for stratification of patients with advanced heart failure.

Complex Congenital Heart Disease: Is Heart Transplantation an Option?

INTRODUCTION: Within the heart transplant (HT) population, few patients have complex congenital heart disease (CHD) underlying disease. Our objective is to assess the complications and follow-up of patients with CHD transplanted in our center (1991-present). MATERIAL AND METHODS: Retrospective analysis of patients older than 14 years old with CHD and HT. Clinical and surgical variables were analyzed. RESULTS: Ten patients (age 25 ± 7 years old, 60% male) were analyzed, which represents 2.2% of the entire series of HT; 9 of the 10 patients were electively transplanted and 1 was under support with extracorporeal membrane oxygenation. Compared with the rest of the transplanted patients, patients with CHD had a lower median age (25 [25-36] vs 53 [15-69]; P < .009); more cardiac surgeries prior to HT (100% vs 14.4%; P < .001); a lower percentage of cardiovascular risk factors (CVRF; 0% vs 60%; P < .001). The left ventricle ejection fraction also showed statistically significant differences (33.5 [12-67] vs 20 [6-70]). CONCLUSIONS: Our patients with CHD and HT are younger and have less CVRF and more cardiac surgeries, which highlights that it is a subgroup with clear clinical differences in its comorbidity and pretransplantation assessment. They also require longer extracorporeal circulation time, more hours of intubation, and more days in the intensive care unit. Primary graft failure is more common in patients with CHD. Therefore, survival at 1-month follow-up is lower than the rest of the series and equalizes after the year of follow-up. This long-term survival reaffirms the possibility of HT in CHD despite the fact that its postoperative period is more difficult.

Short-term Use of Ventricular Assist Device in a Patient With Restrictive Cardiomyopathy: A Case Report.

The CentriMag (Levitronix LLC, Waltham, MA, USA) ventricular assist device is a centrifugal pump designed for short-term support in patients with cardiogenic shock. In patients with restrictive physiology, there is some concern about the use of these devices due a very small ventricular cavity. We review the evolution of a 32-year-old woman with restrictive cardiomyopathy, moderate pulmonary hypertension, and severe biventricular systo-diastolic dysfunction in whom a biventricular Centrimag device was implanted due to a progressive clinical worsening.

Severe heart failure due to noncompaction cardiomyopathy: a case report.

Noncompaction cardiomyopathy involves an infrequent pathology whose diagnosis has been rising in recent years owing to a better understanding of the disease and, therefore, better diagnosis. Today, there are no well established protocols for its treatment. For this reason, it is necessary to adapt the therapy of choice to each patient. We report the case of a 35-year-old man with no past medical history of interest who was admitted due to acute pulmonary edema. Diagnostic tests revealed noncompaction cardiomyopathy with biventricular severe systolic dysfunction. In this situation, heart transplantation was considered to be the best therapeutic option, which was carried out with an uneventful postoperative course. This is one of the few cases reported in the literature for this issue.

Considerations regarding major bleeding after cardiac transplantation.

Postoperative bleeding is one of the most frequent complications after cardiac surgery, leading to longer stays in the intensive care unit (ICU) and the hospital as well as increased morbidity and mortality. We designed an observational prospective study to evaluate early complications after cardiac transplantation, focusing on major bleeding and transfusion requirements. We also evaluated whether massive transfusion was related to increased morbidity and mortality. In patients who received ≥6 blood units, we observed significant differences regarding the need for continuous renal replacement techniques (50% vs 12.5%; P=.01) and ICU mortality (33.3% vs 4%; P=.01). This difference in mortality was also observed when comparing plasma transfusion requirements (35.3% vs 9.4%; P=.04). The overall mortality rate was 24.50%, showing significant differences in patients with massive transfusion (83.3% vs 37.8%; P=.008). In conclusion, perioperative bleeding and massive transfusion were associated with increased morbidity and mortality in this group of patients, which may prompt a review of surgical procedures and the introduction of new techniques, such as thromboelastography.
