Filter by:In non-ischemic dilated cardiomyopathy (NIDCM), left ventricular reverse remodeling (LVRR) can be achieved through guideline-directed medical therapy (GDMT). LVRR is defined as an increase in left ventricular ejection fraction (LVEF) of more than 10% in heart failure patients with a baseline LVEF of 40% or less, or an increase in LVEF of more than 40% at follow-up, which is classified as heart failure with improved EF (HFimpEF) according to current guidelines. Several studies have examined the prevalence and predictors of LVRR in NIDCM. However, there is a lack of research on LVRR in the context of contemporary pharmacotherapy. Studies have demonstrated the beneficial effects of ivabradine in heart failure with reduced ejection fraction (HFrEF), improving patients' prognosis. A sub-study of the SHIFT trial indicated that ivabradine may also contribute to cardiac remodeling reversal in patients with HFrEF. However, there is limited evidence exploring the relationship between ivabradine and LVRR, particularly in the context of NIDCM. Consequently, this study is a retrospective, multi-center cohort study aiming to evaluate the impact of ivabradine on LVRR in patients with NIDCM in the current era of medical therapy. Furthermore, by conducting this study, we aim to gain insights into the potential role of ivabradine in promoting LVRR in NIDCM patients receiving contemporary drug therapy.
Cardiac resynchronization therapy (CRT) with biventricular pacing (BiV) is the cornerstone treatment for heart failure patients with ventricular dyssynchrony. Recently, a new concept, conduction system pacing (CSP) with permanent pacing, including His bundle pacing and left bundle branch pacing, has been proposed as a potential alternative to conventional BiV-CRT. The prospective, randomized trial will compare echocardiographic, electrocardiographic, and clinical effects of CSP versus conventional BiV pacing in heart failure patients with reduced ejection fraction (LVEF ≤ 35%), sinus rhythm, and left bundle branch block. Patients will be randomized to either CSP or biventricular pacing study group and followed up for at least 6 months. The study will explore whether CSP is non-inferior to BiV pacing in echocardiographic, electrocardiographic, and clinical outcomes.
Sacubitril-valsartan, an Angiotensin Receptor Blocker-Neprilysin Inhibitor (ARNI), currently marketed for the management of heart failure, has been shown to reduce cardiovascular morbidity and mortality in stage C heart failure with reduced ejection fraction. In stage C HFpEF, sacubitril-valsartan has also been shown to reduce left atrial volume index measured using echocardiography over a 9 month timeframe. The PARABLE study investigates the hypothesis that sacubitril-valsartan can provide benefits in terms of left atrial structure and function as well as left ventricular structure and function in asymptomatic (stage A/B HFpEF) patients. This is a prospective, randomised, double-blind, double-dummy, phase II study design. The patient population will have hypertension and/or diabetes together with preserved ejection fraction, elevated natriuretic peptide (NP) and abnormal left atrial volume index (LAVI, > 28 mL/m2).
Aortic stenosis (AS) is the most frequent valvulopathy in Western countries. The prevalence of AS is constantly increasing due to the aging of the population. Although significant progress has been made in understanding the pathophysiological mechanisms underlying the onset and progression of AS, there is no medical treatment to slow or prevent its progression. The only treatment available is Aortic Valve Replacement (AVR) performed by surgery or by catheterization (TAVI). AS is associated with an increase of post-load which leads the left ventricular myocardium to hypertrophy. Associated with hypertrophy, myocardial fibrosis will gradually develop. Despite interesting data, many unknowns persist and remain to be identified. The aim of the study is to evaluate prospectively the progression and impact of AS in 500 patients using clinical, biological, echocardiographic and MRI parameters performed annually.

Introduction: In the setting of acute ST-segment elevation myocardial infarction (STEMI) coronary wedge pressure (CWP) emerges as a new marker for the advanced form of pre-procedural microvascular obstruction (MVO), which is associated with inflammatory interstitial edema. Through its anti-inflammatory effects, glucocorticoid therapy may prove beneficial in patients with high CWP. Aim: To identify the presence of the advanced form of MVO before primary percutaneous coronary intervention (PPCI) by CWP measurement and to test the benefit of cortisol therapy, in terms of infarct size and left ventricular remodeling, in patients with raised CWP. Methods: 50 patients with a first STEMI, candidates for PPCI, with proximal coronary occlusion, will undergo CWP measurement followed by percutaneous revascularization. Cardiac MRI will be performed 3-5 days after the procedure. A cutoff for CWP in predicting MVO, interstitial oedema and intramyocardial haemorrhage will be derived.Based on the above mentioned cutoff, 180 patients with continuous elevation of the pressure line will be randomized, by a 1:1 model, either to cortisol therapy or to placebo. Inflammatory parameters will be determined from peripheral blood samples. Patients will undergo cardiac magnetic resonance (CMR) imaging 3 to 5 days after revascularization. Study endpoints: The primary endpoint will be the extent of MVO, interstitial edema and hemorrhage. Secondary endpoints will include infarct size, myocardial salvage, left ventricular volumes and ejection fraction. The clinical endpoints of all-cause and cardiovascular death, myocardial re-infarction, target vessel revascularization, stent thrombosis and stroke will be recorded at 6 months.
The investigators aim to demonstrate that ramipril after transcatheter aortic valve implantation has benefits in terms of prognosis, cardiovascular events and ventricular remodeling (MRI).
To comprehensively characterize Left Ventricular (LV) remodeling after Myocardial Infarction (MI) in the community, study the association between patterns of remodeling and biological pathways and examine the association between the predictors of remodeling and heart failure after Myocardial Infarction.
This randomized phase II trial studies the side effects and how well low-dose carvedilol works in preventing congestive heart failure (CHF) in younger cancer survivors exposed to high dose anthracyclines for management of childhood cancer. Carvedilol may help lower the risk of cardiovascular complications
