To optimize the regenerative proficiency of stem cells, a cardiopoietic protein-based cocktail consisting of multiple growth factors has been developed and advanced into clinical trials for treatment of ischemic heart failure. Streamlining the inductors of cardiopoiesis would address the resource intensive nature of the current stem cell enhancement protocol. To this end, the microencapsulated-modified-mRNA (M3 RNA) technique was here applied to introduce early cardiogenic genes into human adipose-derived mesenchymal stem cells (AMSCs)...

Cardiac resynchronization therapy (CRT) based on biventricular pacing (BVP) is an invaluable intervention currently used in heart failure (HF) patients. The therapy involves electromechanical dyssynchrony, which can not only improve heart function and quality of life but also reduce hospitalization and mortality rates. However, approximately 30% to 40% of patients remain unresponsive to conventional BVP in clinical practice. In the recent years, extensive research has been employed to find a more physiological approach to cardiac resynchronization...

Aortic insufficiency remains a difficult to treat and highly morbid condition even in the era of HeartMate 3 left ventricular assist devices (LVADs). The prognostic nature of the longitudinal progression of aortic insufficiency, however, remains unknown. We prospectively collected data on patients who received HeartMate 3 LVAD implantation, who had assessments of aortic insufficiency using a novel Doppler echocardiography obtained at outflow graft at three (baseline) and 6 months postimplant. Patients with moderate or greater aortic insufficiency at baseline were excluded...

Dyskalemia (hypo- and hyperkalemia) is a common clinical encounter in patients with heart failure (HF), linked to underlying pathophysiologic alterations, pharmacological treatments, and concomitant comorbidities. Both hypo- and hyperkalemia have been associated with a poor outcome in HF. However, it is not known if this association is causal. In order to investigate this relation, we implemented the Bradford Hill criteria for causation examining the available literature. Of note, hypokalemia and low-normal potassium levels (serum potassium < 4...

BACKGROUND AND AIMS: Physical activity (PA) could modify the risk of atrial fibrillation (AF) in the general population and mortality in heart failure patients with preserved ejection fraction (HFpEF). HFpEF patients are frequently concomitant with AF, but whether PA could modify the risk of AF in HFpEF patients remains undiscovered. METHOD AND RESULTS: We performed a post hoc analysis of the TOPCAT trial. Patients without AF at baseline and with data on PA (n = 652) were included...

Left ventricular assist device (LVAD) implantation results in superior survival rates compared with optimal medical therapy in patients with end-stage heart failure. However, a potential complication of LVAD implantation is right heart failure (RHF), which can be devastating. Therefore, identifying preoperative risk factors for RHF and optimal management for these patients are critical for ensuring favorable postoperative outcomes. This review focuses on methods of assessing the risk factors for RHF before surgery, including evaluation of biomarkers, echocardiography, hemodynamics, risk-scoring systems, and existing conditions of right heart dysfunction...

BACKGROUND: Outpatient parenteral antimicrobial therapy (OPAT) facilitates early patient discharge, but readmissions prior to completion of therapy may offset its advantages. The objective of this study was to evaluate unplanned readmissions of patients undergoing OPATat our institution and to identify risk factors. We hypothesized that host factors were most relevant. METHODS: We retrospectively identified all patients discharged to receive OPAT during 2017 who experienced at least one unplanned readmission to the hospital prior to its completion...

The disclosure of proven cardiorenal benefits with certain antidiabetic agents was supposed to herald a new era in the management of type 2 diabetes (T2D), especially for the many patients with T2D who are at high risk for cardiovascular and renal events. However, as the evidence in favour of various sodium-glucose transporter-2 inhibitor (SGLT2i) and glucagon-like peptide-1 receptor agonists (GLP-1 RA) accumulates, prescriptions of these agents continue to stagnate, even among eligible, at-risk patients. By contrast, dipeptidyl peptidase-4 inhibitors (DPP-4i) DPP-4i remain more widely used than SGLT2i and GLP-1 RA in these patients, despite a similar cost to SGLT2i and a large body of evidence showing no clear benefit on cardiorenal outcomes...

BACKGROUND: The population of adults with congenital heart disease (CHD) is growing, and increasingly more patients with CHD reach older ages. Patients with CHD are at an increased risk of myocardial infarction (MI) with increased age. Diagnosing MI in patients with CHD can be challenging in clinical practice owing to a high prevalence of aberrant electrocardiograms, ventricular hypertrophy, and heart failure, among other factors. The National Swedish Patient Register (NPR) is widely used in epidemiological studies; however, MI diagnoses specifically in patients with CHD have never been validated in the NPR...

BACKGROUND: Gemcitabine is a nucleoside analog, widely used either alone or in combination, for the treatment of multiple cancers. However, gemcitabine may also be associated with cardiovascular adverse-drug-reactions (CV-ADR). METHODS: First, we searched for all cases of cardiotoxicity associated with gemcitabine, published in MEDLINE on 30 May 2019. Then, we used VigiBase, the World Health Organization's global database of individual case safety reports, to compare CV-ADR reporting associated with gemcitabine against the full database between inception and 1 April 2019...

While necroptosis has been shown to contribute to the pathogenesis of post-infarction heart failure (HF), the role of autophagy remains unclear. Likewise, linkage between these two cell death modalities has not been sufficiently investigated. HF was induced by 60-min left coronary occlusion in adult Wistar rats and heart function was assessed 6 weeks later followed by immunoblotting analysis of necroptotic and autophagic proteins in both the left (LV) and right ventricle (RV). HF had no effect on RIP1 and RIP3 expression...

BACKGROUND: Pulmonary artery (PA) pulsatility index (PAPi), calculated as (PA systolic pressure - PA diastolic pressure)/right atrial pressure, emerged as a novel predictor of right ventricular failure in patients with acute inferior myocardial infarction, advanced heart failure, and severe pulmonary hypertension. However, the prognostic utility of PAPi in transcatheter mitral valve repair (TMVR) using the MitraClip® system has never been tested. OBJECTIVE: To assess the prognostic impact of PAPi in patients with severe functional mitral regurgitation (MR) and chronic heart failure (CHF) undergoing TMVR...
