We investigated the effects of microRNA-587b (miR-487b) in a rat model of chronic heart failure (CHF). Wistar rats were assigned to 10 groups (n=8 per group). Expression of interleukin-33 (IL-33), somatostatin 2 (ST2), IL-6, and TNF-α was higher in the CHF group than the control group. In the CHF, negative control (NC) for si-IL-33, NC for miR-487b mimic, NC for miR-487b inhibitor, and miR-487b inhibitor + si IL-33 groups, as compared to the blank and sham groups: steroid binding protein (SBP), D binding protein (DBP), left ventricular systolic pressure (LVSP), ± dp/dtmax, and superoxide dismutase (SOD) were all lower; myocardial fibrosis, MDA, left ventricular end-diastolic pressure (LVEDP), myocardial apoptosis rate, IL-6, and TNF-α were all higher; levels of IL-33 and ST2 mRNA and protein were higher; and levels of miR-487b were lower...

Left ventricular assist devices (LVADs) are used in patients with progressive heart failure symptoms to provide circulatory support. Patients with LVADs are referred to inpatient cardiac rehabilitation to prevent postoperative complications and improve aerobic capacity and quality of life (QOL). Preoperative exercise therapy for cardiac patients is an emerging treatment modality, and several studies have reported that it improves postoperative outcomes such as length of hospital stay and postoperative complications...

OBJECTIVES: The main reason for aortic repair failures is recurrent annular dilatation. The fibrous portion of left ventricular outflow tract dilates. A novel device was designed to tackle this problem. METHODS: The device consists of an internal ring applied at the aortic annulus plus an external flexible band at the level of the aortic root. The internal ring has a semi-rigid portion (40%, placed at ventriculo-arterial junction) and a flexible portion to allow it to conform along the curves of the non-coronary/right coronary leaflet and right coronary/left coronary leaflet commissures...

Total chordal preservation is the standard for mitral valve replacement to maintain long-term left ventricular geometry. Whereas it is appropriate for functional and degenerative mitral regurgitation, the role of chordal sparing in rheumatic valve disease is less well understood, with limited evidence supporting total chordal sparing. Inasmuch as this autoimmune disease affects the subvalvular apparatus in addition to the leaflets, it can be expected to continue after surgical repair. Here we present 2 patients who experienced adverse events associated with total chordal sparing mitral replacement as a result of disease progression with rapid fibrous growth causing inflow obstruction and early prosthetic valve failure...

BACKGROUND: Recent clinical and experimental studies have confirmed the effects of Xinfuli Granule (XG), a compound Chinese medicine in the prevention and treatment of heart failure (HF). This study aimed to investigate the effects and the mechanisms of XG on ventricular reconstruction in rats with acute myocardial infarction (AMI). METHODS: Sprague-Dawley rats were subjected to left anterior descending branch ligation. The rats that survived 24 h were randomly assigned to five groups: medium-dose of XG group (MI+XGM), high-dose of XG group (MI+XGH), carvedilol group (MI+C), medium-dose of XG + carvedilol group (MI+C+XGM)...

The role of autoimmunity in cardiovascular (CV) diseases has been increasingly recognized. Autoimmunity is most commonly examined by the levels of circulating autoantibodies in clinical practices. Measurement of autoantibodies remains, however, challenging because of the deficiency of reproducible, sensitive, and standardized assays. The lack of multiplexed assays also limits the potential to identify a CV-specific autoantibody profile. To overcome these challenges, we developed a nanotechnology-based plasmonic gold chip for autoantibody profiling...

BACKGROUND: In contrast to patients with left bundle branch block (LBBB), heart failure patients with narrow QRS and nonspecific intraventricular conduction delay (NICD) display a relatively limited response to cardiac resynchronization therapy. We sought to compare left ventricular (LV) activation patterns in heart failure patients with narrow QRS and NICD to patients with LBBB using high-density electroanatomic activation maps. METHODS AND RESULTS: Fifty-two heart failure patients (narrow QRS [n=18], LBBB [n=11], NICD [n=23]) underwent 3-dimensional electroanatomic mapping with a high density of mapping points (387±349 LV)...

Right ventricular failure (RVF) is the most important prognostic factor for both morbidity and mortality in pulmonary arterial hypertension (PAH), but also occurs in numerous other common diseases and conditions, including left ventricle dysfunction. RVF remains understudied compared with left ventricular failure (LVF). However, right and left ventricles have many differences at the morphological level or the embryologic origin, and respond differently to pressure overload. Therefore, knowledge from the left ventricle cannot be extrapolated to the right ventricle...

Chronic elevation of pulmonary microvascular pressure (Pmv) consistently leads to alveolocapillary barrier thickening and reduction in the filtration coefficient. In animal models of chronic heart failure (CHF) the lung remains dry despite hydrostatic forces. As fluid flux is bi-directional, it has been postulated that an increase in alveolar fluid clearance may facilitate the dry lung when Pmv is chronically elevated. In this study we aimed to examine alveolar fluid clearance in ambulatory patients with CHF secondary to left ventricular (LV) systolic dysfunction compared against non-CHF controls...

Heart failure (HF) with reduced ejection fraction (HFrEF) is a common and costly condition that diminishes patients' health status and confers a poor prognosis. Despite the availability of multiple guideline-recommended pharmacologic and cardiac device therapies for patients with chronic HFrEF, outcomes remain suboptimal. Currently, there is limited insight into the rationale underlying clinical decisions by health care providers and patient factors that guide the use and intensity of outpatient HF treatments...

MitraClip is an approved therapy for mitral regurgitation (MR); however, health care resource utilization pre- and post-MitraClip remains understudied. METHODS: Patients with functional and degenerative MR at high surgical risk in the EVEREST II High-Risk Registry and REALISM Continued-Access Study were linked to Medicare data. Pre- and post-MitraClip all-cause death, stroke, myocardial infarction, heart failure (HF), and bleeding hospitalizations were identified. Inpatient costs, adjusted to 2010 US dollars, were calculated, and event rate ratios and cost ratios were estimated with multivariable modeling...

BACKGROUND: Almost all attempts to improve patient selection for cardiac resynchronization therapy (CRT) using echo-derived indices have failed so far. We sought to assess: the performance of homemade software for the automatic quantification of integral 3D regional longitudinal strain curves exploring left ventricular (LV) mechanics and the potential value of this tool to predict CRT response. METHODS: Forty-eight heart failure patients in sinus rhythm, referred for CRT-implantation (mean age: 65 years; LV-ejection fraction: 26%; QRS-duration: 160 milliseconds) were prospectively explored...
