Background: Longer term quality of life (QOL) outcome in patients who have had a left ventricular assist device (LVAD) explanted due to myocardial recovery (bridge to recovery, BTR) remains uncertain. This study evaluates the QOL of those patients and compares them to bridge-to-transplant (BTT) and transplanted (Tx) patients.
Methods: Anonymized QOL Short Form (SF)-36 questionnaires were sent to a total of 72 patients, including: 14 BTR patients (3.6 +/- 1.9 years since LVAD removal); 29 BTT patients (3.3 +/- 2.3 years since transplantation); and 29 Tx patients (3.8 +/- 0.6 years since transplantation).
Results: Questionnaires were returned by 78.6%, 79.3% and 56.7% of patients from the BTR, BTT and Tx groups, respectively. In all but two of the domains of the SF-36 questionnaire, scores were significantly better in the BTR group compared with the BTT and Tx groups. Analysis of the two main dimensions and the total SF-36 score between the three groups showed that: (i) physical health dimension tended to be better in BTR (71.9 +/- 21) vs BTT (64.5 +/- 23.2) and Tx (41.4 +/- 48) groups (p = not statistically significant [NS]); (ii) mental health dimension was better in both BTR (78 +/- 16.1) and BTT (71.4 +/- 21.1) groups compared with the Tx group (39.4 +/- 44, p < 0.05); and (iii) total SF-36 score was significantly higher in the BTR and BTT groups compared with the Tx group (76.8 +/- 17.6 and 69 +/- 21.1 vs 41.4 +/- 48, p = NS).
Conclusions: BTR patients appear to have better QOL than both BTT and Tx patients. In addition, BTT patients seem to have a better QOL compared with Tx patients, suggesting that placement of ventricular assist devices could improve the physiologic outcome for transplanted patients.

Background: Better risk stratification is needed to evaluate patients with non-ischemic cardiomyopathy (NICM) for prophylactic implantable cardioverter-defibrillators (ICD). Growing evidence suggests cardiac magnetic resonance imaging (CMR) may be useful in this regard.
Objective: We aimed to determine if late-gadolinium enhancement (LGE) seen on CMR (dichotomized as none/minimal <2% vs significant ≥2%) predicts appropriate ICD therapies (primary endpoint) and/or all-cause mortality/transplant/left-ventricular assist device (LVAD) implantation (secondary endpoint) in NICM patients.

Patients with cardiogenic shock (CS) present with critical hemodynamic compromise with low cardiac output (CO) resulting in end-organ dysfunction. Prognosis is closely related to the severity of shock and treatment of patients with CS is resource intensive. In this review, we consider the current treatment paradigms alongside the evidence that underpins them.

Background: Growth differentiation factor (GDF)-15 is a pleiotropic cytokine that is associated with appetite-suppressing effects and weight loss in patients with malignancy.
Objectives: This study aims to investigate the relationships between GDF-15 levels, anorexia, cachexia, and clinical outcomes in patients with advanced heart failure with reduced ejection fraction (HFrEF).
Methods: In this observational, retrospective analysis, a total of 344 patients with advanced HFrEF (age 58 ± 10 years, 85% male, 67% NYHA functional class III), underwent clinical and echocardiographic examination, body composition evaluation by skinfolds and dual-energy x-ray absorptiometry, circulating metabolite assessment, Minnesota Living with Heart Failure Questionnaire, and right heart catheterization.

Background: Left Ventricular Assist Device (LVAD) implantation is an important treatment option for patients with advanced CHF. Referral to an early, intensive cardiac rehabilitation (CR) program in these patients seems still underused. This observational descriptive study aimed to evaluate the feasibility and efficacy of an early intensive CR program in LVAD recipients, also comparing results with a matched group of advanced HFrEF patients.
