ABSTRACT

OBJECTIVE: Atrial fibrillation (AF) and heart failure (HF) are common cardiovascular diseases. The impact of AF on in-hospital outcomes in acute decompensated heart failure (ADHF) is controversial. The aim of this study is to determine the prevalence of AF among hospitalized patients with ADHF and describe the clinical characteristics and in-hospital outcomes of these patients with and without AF. METHODS: We examined the multicenter, observational data from the real-life data of hospitalized patients with HF: Journey HF-TR study in Turkey that studied the clinical characteristics and in-hospital outcomes of hospitalized patients with ADHF between September 2015 and September 2016. RESULTS: Of the 1,606 patients hospitalized with ADHF, 626 (39%) had a history of AF or developed new-onset AF during hospitalization. The patients with AF were older (71±12 vs. 65±13 years; p<0.001) and more likely to have a history of hypertension, valvular heart disease, and stroke. The AF patients were less likely to have coronary artery disease and diabetes. In-hospital adverse event rates and length of in-hospital stay were similar in ADHF patients, both with and without AF. In-hospital all-cause mortality rate was higher in patients with AF than in patients without AF, although the difference was not statistically significant (8.9% vs. 6.8%; p=0.121). CONCLUSION: AF has been found in more than one-third of the patients hospitalized with ADHF, and it has varied clinical features and comorbidities. The presence of AF is not associated with increased adverse events or all-cause mortality during the hospitalization time.

ABSTRACT

BACKGROUND: Analysis of the prognostic effect of concomitant use of left ventricular assist devices (LVADs) and implantable -cardioverter defibrillators (ICDs) is lacking. The aim of this study is to define the survival effects of ICD therapy in ambulatory patients with LVAD. METHODS AND RESULTS: Patients with continuous-flow (cf) LVAD in a single tertiary center from December 2010 to May 2016 were retrospectively analyzed. Over a 6-year period, 257 patients had cf-LVAD implantation, 227 of them survived to discharge after the first month of LVAD implantation and were included in the study. The median follow-up time was 14 months, and 104 (45.8%) patients had ICD. One hundred and thirty-two (58.1%) patients were still under LVAD support at the end of the study period. Forty (17.6%) patients had heart transplantation, and 55 (24.2%) died. There was no significant difference between groups with ICD and without ICD for baseline characteristics except for higher pulmonary pressures and amiodarone use in the ICD group. Survival analysis showed significant survival benefit of ICD therapy (P = .02). After multivariate analyses including age, sex, left ventricular ejection fraction, and ß-blocker usage, the benefit of ICD continued (hazard ratio: 0.54; 95% confidence interval, 0.303-0.975; P = .041). CONCLUSIONS: Ventricular arrhythmias (VAs) do not cause acute hemodynamic deterioration in patients with LVAD. However, VAs might be associated with poor prognosis. The present study showed that ICD therapy may improve survival among ambulatory patients with cf-LVAD-supported heart failure.

ABSTRACT

BACKGROUND AND OBJECTIVES: Testosterone deficiency is associated with mortality in patients with heart failure; however, its effects on patients undergoing Left Ventricular Assist Device (LVAD) implantation are unclear. We investigated the role of total testosterone (TT) and free testosterone (FT) levels on mortality undergoing LVAD implantation. METHODS: Between December 2010 and December 2014, 101 consecutive male patients who underwent LVAD implantation and had plasma testosterone measurement (TT and FT) in the last month before operation were included in the study. Demographics, follow-up, and mortality data were analyzed retrospectively. RESULTS: The mean age of the patients was 51.7 ± 11 years. TT and FT levels were in the below normal range of 31.6% (n = 32) and 65.3% (n = 66) of the patients, respectively. The mean follow-up time was 355 ± 268 days, and 32 (31%) patients died during follow-up. Cumulative survival rates were significantly worse in patients with low TT and FT than patients in the normal range (P < .001 and P = .029, respectively). Multivariate analysis after adjustment for clinical variables, age, albumin, C-reactive protein, total cholesterol, chronic kidney disease, diabetes mellitus (DM), and leukocytosis showed that low TT and FT were independently associated with poor survival (HR, 3.680; 95% CI, 1.615-8.385 P = .002 and HR, 3.816; 95% CI, 1.279-11.383, P = .016, respectively). CONCLUSION: Low TT and FT levels were independent risk factors for mortality in patients with LVAD.

ABSTRACT

BACKGROUND: Right ventricular (RV) function has great impact on the survival of heart transplantation recipients; therefore, careful evaluation is of high clinical importance. However, there is no standard conventional echocardiographic parameter to assess RV systolic function. Herein, we evaluated the correlation between echocardiographic parameters of RV systolic function and ejection fraction assessed by cardiac magnetic resonance imaging (MRI RVEF) in heart transplantation recipients. METHOD AND RESULTS: Forty-three patients with at least 6-month heart transplantation history were included in this study. Each patient had conventional echocardiography and cardiac MRI evaluation, followed by endomyocardial biopsy and right heart catheterization, which were performed in six hours. Echocardiographic parameters of RV systolic function, RV fractional area change (RV FAC), tricuspid annular plane systolic excursion (TAPSE), RV myocardial performance index, and RV global longitudinal strain, were compared with MRI RVEF (P values were <0.001, <0.3, <0.9, and <0.4, respectively). RV FAC was the only parameter to strongly correlate with MRI RVEF (r=0.747, P<0.001); and RV FAC 48.5% value had 90.5% sensitivity and 90.5% specificity to predict the pathologic reference value of MRI RVEF ≤50% (AUC:0.96; 95% CI, 0.908-1.013). CONCLUSION: To our knowledge, this is the first prospective study to evaluate the correlation between the echocardiographic parameters for RV systolic function and MRI RVEF in heart transplantation recipients. RV FAC is the only parameter to correlate well with MRI RVEF, and its routine use in the follow-up of heart transplantation recipients should be considered.

ABSTRACT

OBJECTIVE: Allograft rejection is still an important cause of morbidity and mortality after heart transplantation (HTx). Many techniques in cardiac magnetic resonance imaging (CMR) were investigated to diagnose acute cellular rejection (ACR). However, there is not enough information about late gadolinium enhancement (LGE) in the myocardium and ACR. METHODS: We prospectively analyzed our consecutive 41 heart transplant recipients who were admitted for routine endomyocardial biopsies. CMR was performed maximum 6 h before the scheduled endomyocardial biopsy. Correlation between LGE in the myocardium and ACR was investigated. RESULTS: Twenty-seven patients showed no rejection, and nine of them had LGE in the myocardium. Fourteen patients had LGE in the left ventricle (LV), and two patients had LGE also in the right ventricle (RV). There was no correlation between LGE and ACR (p=0.879). There was no difference in the left ventricular ejection fraction (LVEF), right ventricular fractional area change (RVFAC), and cardiac ischemic time between the groups (p=0.825, p=0.370, and p=0.419, respectively). LGE in the myocardium could be due to previous rejection episodes; therefore, all patients were retrospectively searched for previous rejection grades and number of episodes. Thirty-eight of the 41 patients had a history of one ACR episode, but none of them had a statistically significant correlation with LGE (for grade 1R, p=0.964 and grade 3R, p=1) There was also no correlation between number of rejection episodes history and LGE. CONCLUSION: LGE is not suitable to detect ACR in heart transplant patients. LGE and the history of ACR have no correlation.
