Background Clinical effectiveness of autologous skeletal cell‐patch implantation for nonischemic dilated cardiomyopathy has not been clearly elucidated in clinical settings. This clinical study aimed to determine the feasibility, safety, therapeutic efficacy, and the predictor of responders of this treatment in patients with nonischemic dilated cardiomyopathy. Methods and Results Twenty‐four nonischemic dilated cardiomyopathy patients with left ventricular ejection fraction <35% on optimal medical therapy were enrolled. Autologous cell patches were implanted over the surface of the left ventricle through left minithoracotomy without procedure‐related complications and lethal arrhythmia. We identified 13 responders and 11 nonresponders using the combined indicator of a major cardiac adverse event and incidence of heart failure event. In the responders, symptoms, exercise capacity, and cardiac performance were improved postoperatively (New York Heart Association class II 7 [54%] and III 6 [46%] to New York Heart Association class II 12 [92%] and I 1 [8%], P <0.05, 6‐minute walk test; 471 m [370–541 m] to 525 m [425–555 m], P <0.05, left ventricular stroke work index; 31.1 g·m 2 ·beat [22.7–35.5 g·m 2 ·beat] to 32.8 g·m 2 ·beat [28–38.5 g·m 2 ·beat], P =0.21). However, such improvement was not observed in the nonresponders. In responders, the actuarial survival rate was 90.9±8.7% at 5 years, which was superior to the estimated survival rate of 70.9±5.4% using the Seattle Heart Failure Model. However, they were similar in nonresponders (47.7±21.6% and 56.3±8.1%, respectively). Multivariate regression model with B‐type natriuretic peptide, pulmonary capillary wedge pressure, and expression of histone H3K4me3 (H3 lysine 4 trimethylation) strongly predicted the responder of this treatment (B‐type natriuretic peptide: odds ratio [OR], 0.96; pulmonary capillary wedge pressure: ​OR, 0.58; H3K4me3: OR, 1.35, receiver operating characteristic–area under the curve, 0.96, P <0.001). Conclusions This clinical trial demonstrated that autologous skeletal stem cell–patch implantation might promise functional recovery and good clinical outcome in selected patients with nonischemic dilated cardiomyopathy, in addition to safety and feasibility.

Background: Recent data demonstrate promising effects on left ventricular dysfunction and left ventricular ejection fraction (LVEF) improvement following ablation for atrial fibrillation (AF) in patients with heart failure. We sought to study the relationship between LVEF, New York Heart Association class on presentation, and the end points of mortality and heart failure admissions in the CASTLE-AF study (Catheter Ablation for Atrial Fibrillation With Heart Failure) population. Furthermore, predictors for LVEF improvement were examined. Methods: The CASTLE-AF patients with coexisting heart failure and AF (n=363) were randomized in a multicenter prospective controlled fashion to ablation (n=179) versus pharmacological therapy (n=184). Left ventricular function and New York Heart Association class were assessed at baseline (after randomization) and at each follow-up visit. Results: In the ablation arm, a significantly higher number of patients experienced an improvement in their LVEF to >35% at the end of the study (odds ratio, 2.17; P <0.001). Compared with the pharmacological therapy arm, both ablation patient groups with severe (<20%) or moderate/severe (≥20% and <35%) baseline LVEF had a significantly lower number of composite end points (hazard ratio [HR], 0.60; P =0.006), all-cause mortality (HR, 0.54; P =0.019), and cardiovascular hospitalizations (HR, 0.66; P =0.017). In the ablation group, New York Heart Association I/II patients at the time of treatment had the strongest improvement in clinical outcomes (primary end point: HR, 0.43; P <0.001; mortality: HR, 0.30; P =0.001). Conclusions: Compared with pharmacological treatment, AF ablation was associated with a significant improvement in LVEF, independent from the severity of left ventricular dysfunction. AF ablation should be performed at early stages of the patient’s heart failure symptoms.

Peripartum cardiomyopathy is an uncommon, pregnancy-related form of dilated cardiomyopathy that is associated with development of new-onset left ventricular dysfunction. Its etiology is presently unknown, but current standard of care involves the use of typical drug therapy for the treatment of heart failure. Pregnancy-associated cardiomyopathy (PACM) is a similar condition that refers to patients who develop such symptoms prior to the last month of pregnancy. We report the case of a nulliparous Caucasian female who develops early, severe PACM during her first pregnancy with postpartum persistence of New York Heart Association class II-III symptoms despite medical therapy. The use of the novel heart failure agent, sacubitril/valsartan (Entresto), is initiated with near-complete resolution of her symptoms.

Medication knowledge and assistance in older chronic heart failure (CHF) patients. Medication adherence is central to the optimal management of CHF. Little is known about older patients’ knowledge of their medications or the factors that contribute to this knowledge. Aim: To describe and identify the predictors of medication knowledge in older CHF patients. Method: Subjects ( n = 62) aged over 55 years with moderate heart failure (New York Heart Association Class II and III) who identified as self-managing were recruited from hospital or rehabilitation. Interviews occurred at home four weeks post-discharge using a medication checklist and the Self-Efficacy in Chronic Illness Scale (Lorig et al, 2001). Multiple regression analysis determined the predictors of medication knowledge. Results: Patients were aged mean 78.4 years (sd 8.54 years), mostly male (57%) and had an average 8 (median, range 3–22) medications to take daily, of which 6 (median, range 3–14) were for CHF. Most managed their own medications (54%) but more than a quarter (28%) were assisted by reminding, dispensing and supervision. Compliance with medications was high (84%), although only half (53%) knew the name, main purpose and side effect of their medications. Patients with better self-efficacy (β = 2.88) and no help with medication (β = -21.05) had better medication knowledge (model F = 13.6, p = .000, R = .61, r 2 = .37). Conclusion: Older CHF patients have poor knowledge of their medications, which may be improved by promoting overall self-efficacy for disease management. Less knowledgeable patients received appropriate assistance with medications, but the consequence may be less knowledge and thus warrants further investigation.

Background: Since stroke volume (SV) is a function of ejection fraction (EF) and end-diastolic volume (EDV) (SV = EF x EDV), we hypothesized that increased EDV may be advantageous in systolic heart failure (HF), allowing the left ventricle to supply increased cardiac output. Methods: Echocardiograms from 968 consecutive patients seen in our hospital’s HF clinic were reviewed. Left ventricular volumes were measured both at end systole and end diastole using the bi-plane Simpson’s method and were indexed to body surface area. EF was calculated using (EDV-ESV)/EDV. Dates of subsequent HF events (death or admission for HF exacerbation) were obtained from our database. Results: Systolic HF (EF < 50%) was found in 649 of the study subjects. Increased SV index was associated with increased EDV index. The strength of this association varied with EF, Figure. In a bivariate Cox regression model, lower SV index and higher EDV index were each independent predictors of HF events. Increase in EDV by 50 cc was associated with a 20% increase in HF events, p<0.001. Decrease in SVI by 5 cc was associated with 5% increase in HF events, p<0.001. These associations were limited to those with systolic HF. The associations between both EDVI and SVI and HF events were not confounded by patient age, sex and New York Heart Association Class. Conclusion: Increased EDV index was independently associated with increased HF events, indicating that LV enlargement in HF is not favorable. These findings underscore the individual contributions of the components of EF (SV and EDV) in predicting HF outcomes.

Introduction: The use of an implantable cardioverter-defibrillator reduces the probability of sudden cardiac death in patients with heart failure.Objective: To determine the cost-utility relationship of an implantable cardioverter-defibrillator compared to optimal pharmacological therapy for patients with ischemic or non-ischemic New York Heart Association class II or III (NYHA II-III) heart failure in Colombia.Materials and methods: We developed a Markov model including costs, effectiveness, and quality of life from the perspective of the Colombian health system. For the baseline case, we adopted a time horizon of 10 years and discount rates of 3% for costs and 3.5% for benefits.The transition probabilities were obtained from a systematic review of the literature. The outcome used was the quality-adjusted life years. We calculated the costs by consulting with the manufacturers of the device offered in the Colombian market and using national-level pricing manuals. We conducted probabilistic and deterministic sensitivity analyses.Results: In the base case, the incremental cost-effectiveness ratio for the implantable cardioverter-defibrillator was USD$ 13,187 per quality-adjusted life year gained. For a willingness-to-pay equivalent to three times the gross domestic product per capita as a reference (USD$ 19,139 in 2017), the device would be a cost-effective strategy for the Colombian health system. However, the result may change according to the time horizon, the probability of death, and the price of the device.Conclusions: The use of an implantable cardioverter-defibrillator for preventing sudden cardiac death in patients with heart failure would be a cost-effective strategy for Colombia. The results should be examined considering the uncertainty.
