Filter by: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.
This is a single-center, prospective, observational controlled cohort study designed to describe the role of WNT/B-catenin signaling and adenosine system after an acute myocardial infarction, correlating it with clinical markers of fibrosis/remodeling (primary objective). The modulation of the aforementioned molecular patterns will also be evaluated in light of the type of P2Y12 inhibitor implemented (ticagrelor or prasugrel) to identify variations in response (secondary objective).
The study intends to investigate the alteration of regional myocardial work in patients with acute anterior myocardial infarction underwent primary percutaneous coronary intervention (PCI), and compare the distribution of regional myocardial work in patients with/without early remodeling at acute phase and 3-month follow-up.
This study investigates damage of the right cardiac chamber in adult patients with a congenital heart defect involving the pulmonary valve (the heart valve between the right cardiac chamber and the lungs). The investigators want to investigate if novel, less invasive techniques are feasible to assess damage of this right cardiac chamber, to improve follow-up and timing of intervention (valve replacement) in this group of patients.
Results from recent clinical trials on bone marrow mononuclear cell (BM-MNC) transplantation show that this intervention can help reduce the incidence of heart failure (HF) after acute myocardial infarction (AMI). However, no study has evaluated the effect of the transplantation of mesenchymal stem cells (MSCs) on a clinical endpoint such as HF. This single-blinded, randomized, multicenter trial aims to establish whether the intracoronary infusion of umbilical cord-derived Wharton's jelly MSCs (WJ-MSCs) helps prevent HF development after AMI. The study will enroll 240 patients 3 to 7 days following an AMI treated with primary percutaenous coronary intervention (PPCI). Only patients aged below 65 years with impaired LV function (LVEF < 40%) will be included. They will be randomized to receive either a single intracoronary infusion of WJ-MSCs or standard care. The primary outcome of this study is the assessment of HF development during long-term follow-up (four years). Since the efficacy of MSCs is higher than BM-MNCs after AMI in the improvement of LVEF, it would be probable that these cells may have a better clinical effect as well. However, no study has evaluated the impact of the transplantation of MSCs on a clinical endpoint such as HF. This study will help determine whether or not the infusion of intracoronary WJ-MSCs in patients
To explore the protective effect of prostaglandin sodium on coronary microcirculation function and ventricular remodeling after reperfusion treatment of acute ST-segment elevation myocardial infarction.
This study is designed to evaluate the efficacy and safety of compound Danshen dropping pills (CDDP) in improving ventricular remodeling and cardiac function after acute anterior wall ST-Elevation myocardial infarction(STEMI). 268 patients with acute anterior wall STEMI after primary Percutaneous Coronary Intervention (pPCI) are randomly assigned 1:1 to CDDP group(n=134) and control group(n=134) with follow-up of 24 weeks. Both groups are treated with standard therapy of STEMI, with the CDDP group administrating 20 tablets of CDDP before pPCI and 10 tablets three times a day after pPCI and the control group treated with placebo at the same time. The primary endpoint is 24-week echocardiographic including left ventricle ejection fraction (LVEF) , left ventricular end-diastolic volume index (LVEDVI) and left ventricular end-systolic volume index (LVESVI).The secondary endpoint is the change in N terminal pro-B-type natriuretic peptide（NT-proBNP ）level, arrhythmia and cardiovascular events (death, cardiac arrest or cardiopulmonary resuscitation, hospitalization due to heart failure or angina pectoris).
failure of closure of the ductus arteriosus after birth results in a congenital anomaly known as patent ductus arteriosus. The large ductus can induce left side heart remodeling changes which could interfere with the normal cardiac function.
The primary objective of the PERI-STEMI trial is to assess whether sacubitril-valsartan is more effective in preventing adverse LV remodeling for patients with ST-elevation myocardial infarction (STEMI) than enalapril.
The main goal of the project is to prove that ultra-high-frequency ECG (UHF-ECG) can be used as a diagnostic tool that allows the prediction of patients susceptible to the negative effect of right ventricular myocardial pacing. The prediction will be based on the assessment of electrical dyssynchrony and local depolarization durations of left ventricular depolarization emerging during right ventricular pacing. If proved to be valid in left ventricular negative remodeling prediction, UHF-ECG-derived parameters of ventricular dyssynchrony could be used as markers allowing a lead placement optimization during an implant procedure. This information can help the operator to identify patients with the urgent need for physiological pacing (HB or LBBp) and patients in which a right ventricular myocardial pacing is sufficient and will not lead to the development of the negative left ventricular remodeling.
