Active clinical trials for "Ventricular Remodeling"

The study aims to assess the effect of superselective adrenal arterial embolization on ventricular remodeling in primary aldosteronism without lateralized aldosterone secretion by comparing it with spironolactone therapy.

A multicenter, randomized, double-blind, placebo-controlled phase III clinical trial to evaluate the effect of recombinant human Neuregulin-1 for injection on cardiac function and reverse ventricular remodeling in male patients with NT-proBNP ≤ 1700 pg/ml and female patients with NT-proBNP ≤ 4000 pg/ml and New York Heart Association class II-III chronic systolic heart failure, and to confirm its efficacy and safety.

Methodology This study will enroll (120) patients presenting with acute anterior STEMI who will undergo early reperfusion presenting at Helwan University Hospitals and Ain Shams University Hospitals. Diagnosis of STEMI will be based on: Sustained ST-segment elevation of at least 1 mm in at least 2 contiguous leads or new/presumably new left bundle branch block, plus >Typical anginal pain, or > diagnostic levels of serum cardiac biomarkers, or > imaging evidence of new loss of viable myocardium or new regional wall motion abnormality. They will be subdivided into two (2) groups according to Dapagliflozin intake into: - Group A: Patients with diabetes mellitus (DM) (60) patients, they will be further subdivided into 2 subgroups: Group A1: 30 patients will receive Dapagliflozin in addition to standard anti-ischemic and anti-diabetic treatment. Group A2: 30 patients will receive standard anti-ischemic and antidiabetic treatment (Dapagliflozin not included). - Group B: Patients without DM (60) patients, subdivided to 2 subgroups: Group B1: 30 patients will receive standard anti-ischemic treatment. Group B2: 30 patients will receiv up e standard anti-ischemic treatment and Dapagliflozin. Methodology in details: The study patients will undergo early reperfusion according to the recent practice guidelines and the local hospital policy in managing ST elevation MI patients. Echocardiography will be performed twice: within 48 hours of admission and 3 months following the index event. Management: Twelve-lead electrocardiogram will be recorded at baseline and 30-min post-procedure. The ST-segment changes will be evaluated in the single lead with the most prominent ST-segment elevation before intervention. The ST-segment elevation will be measured to the nearest 0.5 mm at 60 ms after the J point. Significant ST segment resolution (STR) is defined as a reduction in ST-segment elevation of 50% after 30 min of infarct artery recanalization. Immediately before the procedure, patients will receive aspirin (300 mg), ticagrelor (180 mg) or clopidogrel (600 mg) depending on availability. Adjunctive pharmacological treatment during the procedure will include: Unfractionated heparin as an initial bolus of 70 U/kg and additional boluses during the procedure to achieve an activated clotting time of 250 to 350 s (200 to 250 s if Glycoprotein IIb/IIIa (GPIIb/IIIa) antagonist is used). Heparin will be discontinued at the end of percutaneous coronary intervention. The use of a GPIIb/IIIa antagonist during the procedure, primary PCI technique, indications, and methods of thrombectomy if indicated will be done under the regulations of the local hospital policy and the most recent practice guidelines.

This study aim to investigate the effect of ivabradine on reducing infarct size and improving left ventricular remodeling after in patients undergoing primary PCI for ST-elevation myocardial infarction through myocardial enhanced MRI.

Long COVID or Postacute sequelae of COVID-19 infection (PASC) are increasingly recognised complications, defined by lingering symptoms, not present prior to the infection, typically persisting for more than 4 weeks. Cardiac symptoms due to post-acute inflammatory cardiac involvement affect a broad segment of people, who were previously well and may have had only mild acute illness (PASC-cardiovascular syndrome, PASC-CVS). Symptoms may be contiguous with the acute illness, however, more commonly they occur after a delay. Symptoms related to the cardiovascular system include exertional dyspnoea, exercise intolerance chest tightness, pulling or burning chest pain, and palpitations (POTS, exertional tachycardia). Pathophysiologically, Long COVID relates to small vessel disease (endothelial dysfunction) vascular dysfunction and consequent tissue organ hypoperfusion due to ongoing immune dysregulation. Active organs with high oxygen dependency are most affected (heart, brain, kidneys, muscles, etc.). Thus, cardiac symptoms are often accompanied by manifestations of other organ systems, including fatigue, brain fog, kidney problems, myalgias, skin and joint manifestations, etc, now commonly referred to as the Long COVID or PASC syndrome. Phenotypically, PostCOVID Heart involvement is characterised by chronic perivascular and myopericardial inflammation. We and others have shown changes using sensitive cardiac MRI imaging that relate to cardiac symptoms (Puntmann et al, Nature Medicine 2022; Puntmann et al, JAMA Cardiol 2020; Summary of studies included in 2022 ACC PostCOVID Expert Consensus Taskforce Development Statement, JACC 2022, references below). Early intervention with immunosuppression and antiremodelling therapy may reduce symptoms and development of myocardial impairment, by minimising the disease activity and inducing disease remission. Low-dose maintenance therapy may help to maintain the disease activity at the lowest possible level. The benefits of early initiations of antiremodelling therapy to reduce symptoms of exercise intolerance are well recognised, but not commonly employed outside the classical cardiology contexts, such as heart failure or hypertension. As most patients with inflammatory heart disease only have mild or no structural abnormalities, they are left untreated (standard of care). The aim of this study is to examine the efficacy of a combined immunosuppressive / antiremodelling therapy in patients with PASC symptoms and inflammatory cardiac involvement determined by CMR, to reduce the symptoms and inflammatory myocardial injury and thereby stop the progression to reduced LVEF, HF and death.

For patients with anterior ST elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI), whether early application of proprotein convertase subtilisin kexin type 9 (PCSK9) inhibitors to rapidly reduce low-density lipoprotein cholesterol (LDL-C) before PCI could effectively inhibit left ventricular remodeling has been rarely reported. The aim of this study was to investigate the effect of early application of PCSK9 inhibitors Evolocumab to rapidly reduce LDL-C levels before primary PCI treatment on left ventricular remodeling in STEMI patients. Eligible patients were randomly randomized 1:1:1 to one of the following three groups immediately after enrollment: (1) Intensive statin group: rosuvastatin 20 mg per day, in addition to usual therapy; (2) Combined intensive statin and PCSK9 inhibitor group: rosuvastatin 20 mg per day and subcutaneous injection of evolocumab 140 mg twice a month, for at least 3 months, and preferably 6 months; (3) PCSK9 inhibitor alone group: subcutaneous injection of evolocumab 140 mg, twice a month for at least 3 months and preferably 6 months.

The primary objective of this study is to assess the effect of early and rapid treprostinil therapy for mean pulmonary artery pressure (mPAP) reduction to improve right ventricular (RV) function and reverse RV remodeling in participants with pulmonary arterial hypertension (PAH).

Previous experience with cardiac resynchronization therapy (CRT) candidates suggests that selection of these patients can be improved. Current clinical guideline approaches are mainly too unspecific and lead to a high non-responder rate of 30-40%, which causes a burden on health care systems and puts patients at risk of an unnecessary treatment who might benefit more from a conservative approach. Previous work indicated that using the assessment of mechanical dyssynchrony on echocardiography can lower the non-responder rate at least by 50% without compromising sensitivity for detecting amendable patients. The current prospective, randomized, multi-center trial was therefore designed to prove that the characterization of the mechanical properties of the left ventricle can improve patient selection for CRT. Patients will be randomized into one of two study arms: a control study arm with treatment recommendation based on clinical guidelines criteria, or an experimental study arm with treatment recommendation based on the presence of mechanical dyssynchrony. All patients will receive a CRT implantation. In the control study arm, bi-ventricular pacing will be turned on. In the experimental study arm, bi-ventricular pacing will be turned on or off, depending on the presence or absence of mechanical dyssynchrony, respectively. The primary endpoint will be non-inferiority in outcome of a treatment recommendation based on mechanical dyssynchrony, achieved with a lower number of CRT devices implanted, effectively leading to a lower number needed to treat. Outcome measures are the average relative change in continuously measured LVESV per arm and the percentage 'worsened' according to the Packer Clinical Composite Score per arm after 1 year follow-up.

The study compares the effectiveness of treatment with MitraClip to medical therapy in improving the reduction of cardiovascular morbidity and functional capacity at 24 months, in patients with moderate functional mitral regurgitation.

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
