CardioInsight 3 - LBBB
Heart FailureBackground Cardiac Resynchronization Therapy (CRT) is proven to improve survival and heart function of patient with certain electrical conduction abnormality and heart failure. However, in patient with certain electrical conduction abnormality, being nonresponder is observed in up to 40% in patient receiving CRT. Conventionally the surgical approach of CRT is to implant one pacing lead in the right heart and one in the left heart to resynchronize the contraction and the pacing lead in the left heart is usually placed in the posterior or lateral portion of the left heart. However, this single approach may not be optimal, especially for those patients with conduction abnormality known to have no response to CRT. Purpose of the clinical investigation The purpose of the Activation Pattern and Acute Hemodynamics of His and Left Bundle Pacing is to study the acute effect on the heart function and conduction abnormality of His and left bundle pacing in conventional CRT candidate. During CRT implantation, Hisbundle lead and Left bundle pacing lead will be placed and the acute effect on heart function will be studied by a wire placed in the left ventricle of the heart and the activation pattern will be studied by a noninvasive global mapping system. The pacing approach that optimally corrects conduction abnormality and improvement on the heart function acutely will be determined
LBBP as Initial Therapy in Patients With Non-ischemic Heart Failure and LBBB
Non-ischemic CardiomyopathyHeart Failure1 moreThe present study will recruit 50 symptomatic non-ischemic cardiomyopathy (NICM) patients with left ventricular ejection fraction (LVEF) below 35% and complete left bundle branch block (CLBBB), who have not received complete guideline-directed medical therapy (GDMT). Each patient was randomized to 2 groups, GDMT or left bundle branch pacing combined with GDMT (LBBP+GDMT) as initial therapy and was followed up for 2 phases: 0-6 months (phase I), 7-18 months (phase II). The primary objective is to compare the LVEF change , syncope and malignant ventricular arrhythmias between GDMT group and LBBP+GDMT group, and to observe which strategy will significantly reduce the percentage of recommendations for an implantable cardioverter-defibrillator (ICD) during phase I study. The second outcome measures including health economics, echocardiography parameters[left ventricular ejection fraction (LVEF), left ventricular end-systolic volume (LVESV), left ventricular end-diastolic volume (LVEDV)], N-terminal pro B-type natriuretic peptide (NT-proBNP) level, New York Heart Association (NYHA) class, 6-minute walking distance (6MWD), quality of life score(QOL) and incidence of clinical adverse events.
A Study to Learn How Well the Drug Vericiguat Works and How Safe it is Under Real World Conditions...
Chronic Heart Failure With Reduced Ejection FractionWorsening Heart FailureResearchers are looking for a better way to treat people who have chronic heart failure with reduced ejection fraction (HFrEF). HFrEF is a long-term condition where the left side of the heart does not pump blood out to the body as well as it should. Blood and fluid may collect in the lungs, blood vessels, and tissues causing shortness of breath or tiredness. Over time, heart failure can lead to other serious medical conditions that may result in hospital stays and death. Despite various available treatments for long-term HFrEF, people may experience worsening of their condition, called worsening heart failure events. Worsening heart failure events require the patient to either stay in the hospital or receive special treatment to remove excess water from the body. The drug vericiguat works by increasing the activity of an enzyme called soluble guanylate cyclase (sGC). The sGC enzyme helps to regulate the heart and blood circulation. Vericiguat was recently approved in India for doctors to prescribe to people with HFrEF after they had a worsening heart failure event, with a request to specifically gather information on vericiguat therapy in Indians. Therefore, the main purpose of this study is to learn more about how well vericiguat works in Indian people with HFrEF who receive vericiguat after a worsening heart failure event. Work well means to prevent: death due to heart and circulatory events, or hospital stays. Researchers will collect the number of participants treated with vericiguat who have either of this. To find out how safe vericiguat is, researchers will also collect the number of participants who have medical problems during the study. Doctors keep track of all medical problems, even if they do not think the adverse events might be related to the study treatments. The participants will take vericiguat as tablet by mouth and as prescribed by their doctors according to the local label. Each participant will be in the study for approximately 1 year including a screening period of up to 1 month. Up to 8 visits to the study site are planned. During the study, the study team will: check vital signs do physical examinations examine heart health using electrocardiogram ECG and if needed echocardiography take blood and urine samples
Initiation of ARNi and SGLT2i in Patients With HFrEF
Heart Failure With Reduced Ejection FractionHeart failure (HF) is a condition in which the heart does not contract ("pump") or relax well, leading to insufficient perfusion of vital organs. Ankle swelling, fatigue, and breathlessness are some of the features of this syndrome. There are different causes for HF (e.g., infarct and hypertension) and two distinct types: HFpEF - HF with preserved ejection fraction - the heart "pumps" but does not relax well and HFrEF/HFmrEF - HF with reduced or mildly reduced ejection fraction - where the heart does not "pump" properly. Patients with HFrEF experience substantially shorter life expectancies compared with people in the general population of similar age. Compared to the different available therapeutics for HFrEF patients, angiotensin receptor-neprilysin inhibitor (ARNi), sacubitril/valsartan, has shown superiority for improving clinical outcomes. Furthermore, the new recently drug sodium-glucose cotransporter 2 inhibitor (SGLT2i) was proven to reduce mortality and morbidity on top of well-adapted background therapy. This work aims to test the safety of ARNi and SGLT2i initiation by comparing a strategy of simultaneous initiation of ARNi and SGLT2i versus sequential initiation of a SGLT2i first followed by an ARNi.

The Anti-myocardial Fibrosis Effect of Vericiguat in HFrEF
Heart Failure With Reduced Ejection FractionVericiguat is a new medication therapy choice for the patients with heart failure with reduced ejection fraction (HFrEF), in the latest trial, it met the expectation to reduce incidence of death from cardiovascular causes or hospitalization for heart failure among HFrEF patients. Myocardial fibrosis as a pathological change in heart failure, it contributes to left ventricular dysfunction leading to development of the disease, experimental studies have showed the potential prevention, or even reversal effect of sGC stimulators in left ventricular hypertrophy and fibrosis. Our study is a prospective controlled clinical trial aim to verify the anti-myocardial fibrosis effect of vericiguat in heart failure with reduced ejection fraction.

Hemodynamic Effects of Modulating Circulating Ketone Bodies With 1,3-butanediol
Heart FailureHeart Failure (HF) is a major public health issue affecting 1-2% of the Western population and the lifetime risk of HF is 20%. Despite major improvements in the management and care of patients with HF, the 1-year mortality in patients with HF is high. Furthermore, patients with HF have markedly decreased physical capacity and quality of life. Thus, there is a need for new treatment modalities in this group of patients. In a first-in-man study we have recently discovered that 3-OHB-infusion increases cardiac output by 2 L/min (40% relative increase) and left ventricular (LV) ejection fraction (LVEF) by 8% in absolute numbers in patients with HF and reduced LVEF (HFrEF). 1,3-Butanediol (BD) serves as a potential nutritional supplement in providing long-lasting ketosis as a treatment option in heart disease. Whether BD provides similar hemodynamic effects as ketone monoester remains unknown. Hypothesis Oral BD increases cardiac output and LV function in patients with HFrEF. Aims To investigate the acute hemodynamic effects of weight-adjusted oral BD supplements in patients with HFrEF. Design In a randomized, single-blind, placebo-controlled, crossover design, 12 patients with HFrEF are studied following overnight fast on 2 separate visits in random order: 1) during intake of BD (HVMN, San Francisco, California, USA) and during placebo. Methods Transthoracic echocardiography, non-invasive blood pressure, and venous blood samples are obtained every 60 minutes from baseline until 6 hours following BD ingestion.
