NCT07329699
The AIM-FFR trial is a prospective, multi-center, open-label, randomized controlled, non-inferiority trial. The current trial will evaluate non-inferiority of MPFFR-guided PCI, compared with invasive FFR-guided PCI in patients with coronary artery disease.
NCT06863155
Patients receiving chronic oral anticoagulation with indication for percutaneous coronary revascularization with stent implantation, and needing for antiplatelet therapy, are at high risk of bleeding. The new generation of ultrathin strut sirolimus-eluting stent with bioabsorbable polymer allow for shorter antiplatelets regimens and could be a good option for this high-bleeding risk patients.
NCT07396792
It is a prospective, controlled, single-center, observational, non-randomized study. The study is planned to include at least 4000 patients 18 years old and older in the training sample and 1000 patients over 18 years old in the test sample (the total number of patients is at least 5000 people). Patients will be included in the study if they have undergone a full examination (laboratory, clinical and instrumental), allowing for the verification or exclusion of cardiac and cardiac-associated pathology in accordance with current recommendations. During the course of the study, the authors of the work do not interfere with the above-mentioned scope of the examination, which is carried out on patients in accordance with clinical guidelines. All patients included in the study will undergo ECG recording in standard lead I for 1 minute twice, followed by spectral analysis of the obtained data, which will be stored at the remote monitoring center of Sechenov University without being linked to the personal data of patients. A spectral analysis of the electrocardiogram will be performed using a continuous wavelet transform. The result of this study will be the identification of ECG parameters that will correlate with cardiac and cardiac-associated pathology
NCT05360446
CKJX839D12303 is a research study to determine if the study treatment, called inclisiran, in comparison to placebo taken in addition to statin medication can effectively reduce the total amount of plaque formed in the heart's vessels as measured by coronary computed tomography angiography (CCTA) from baseline to month 24. This study is being conducted in eligible participants with a diagnosis of non-obstructive coronary artery disease (NOCAD), where the coronary arteries are blocked less than 50%, and with no previous cardiovascular events.
NCT03971500
Prospective, multicenter, randomized, double-blind, placebo-controlled trials.
NCT07349979
To evaluate whether percutaneous coronary intervention (PCI) with contemporary drug-eluting stents (DES) combined with guideline-directed medical therapy (GDMT), compared to GDMT alone, reduces the time to first occurrence of major adverse cardiovascular events (MACE) through 12 months in patients with ischemic cardiomyopathy and a left-ventricular ejection fraction (LVEF) ≤40%. MACE is a composite of cardiovascular \[CV\] death, spontaneous myocardial infarction (MI), any unplanned revascularization, heart failure (HF)-related rehospitalization, heart transplantation, requirement of device implantation (e.g., valvular treatment, pacemaker, or left ventricular assist device \[LVAD\]), or requirement of intravenous medications due to worsening heart failure in outpatients.

NCT05461729
Brief Summary: Cardiac rehabilitation (CR) is a multi-factorial intervention, designed to limit the physiological and psychological effects of cardiovascular disease such as coronary artery disease (CAD), manage symptoms, and reduce the risk of future cardiovascular events. CR is a structured program not only addressing CAD but also comorbidities including hypertension, dyslipidemia, diabetes and obesity as well as other risk factors. CR aims at long-term lifestyle changes to reduce modifiable risk factors, and it's success depends on a large number of interacting variables including biological, psychological and social factors. Recently, the importance of patient-centered approaches to secondary prevention and CR success has been underlined but intra-individual factors and their interactions are not well understood. The TIMELY prospective study aims to collect high-resolution data for data mining and artificial intelligence machine learning models to identify dependencies between factors and predict favorable outcomes of CR. Data collection will include data documented during controlled center-based CR as well as remote-measurement of physical activity data, (central) blood pressure and pulse wave analysis as well as long-term ECG data during a 6-months period after discharge. Follow-up assessments will be performed at least at 6 months and at 12 months after discharge. Events (MACCE) will be collected for up to 10 years. After 2023, the study will be run under the acronym PrädiktoR. Main objectives of the study: 1. To examine uptake and adherence to a healthy lifestyle (i. e. adherence to CR guidelines in CAD) and the effects on long-term outcomes. 2. To identify potentially mediating mechanisms and predictive factors for long-term CR success in CAD, also to be used in machine learning models and for the generation of digital twins. 3. To investigate acceptance of different eHealth components as well as expectations and needs among CAD patents in CR.
NCT07496281
The OPTIA-AF trial is a prospective, multicenter randomized controlled trial designed to evaluate a rhythm-guided antithrombotic strategy in patients with atrial fibrillation (AF) who maintain durable sinus rhythm after catheter ablation and have a history of prior drug-eluting stent (DES) implantation. Current guidelines generally recommend long-term oral anticoagulation (OAC) in patients with AF, even after successful ablation, while antiplatelet therapy remains essential for prevention of coronary ischemic events following percutaneous coronary intervention. OPTIA-AF tests whether discontinuation of non-vitamin K antagonist oral anticoagulant (NOAC) therapy with transition to single antiplatelet therapy (SAPT) is non-inferior to continued NOAC therapy in patients who maintain sinus rhythm for at least 12 months after AF ablation. Participants will be randomized in a 1:1 ratio to either continued NOAC therapy or NOAC discontinuation with SAPT. The primary endpoint is a 24-month composite net clinical outcome including ischemic stroke, systemic embolism, myocardial infarction, definite or probable stent thrombosis, cardiovascular death, and major bleeding.
NCT07493603
The goal of this clinical trial is to learn if Yiyang Huoluo Decoction (a custom Chinese herbal medicine) works safely and effectively to treat coronary heart disease with atherosclerosis in older adults. It also aims to find out how this herbal treatment may affect blood vessel health and repair at a cellular level. The main questions it aims to answer are: * Does adding Yiyang Huoluo Decoction to standard Western medical care improve symptoms and heart-related health in older adults with coronary heart disease and atherosclerosis? * Is Yiyang Huoluo Decoction safe for older adults to take alongside their regular heart medications? * How does this herbal treatment affect the damaged blood vessels in study participants? Researchers will compare two groups of participants to see if the combined treatment works better than standard care alone. Who can take part: Older adults diagnosed with coronary heart disease and atherosclerosis who meet the study's health and eligibility rules. What participants will do: * Be split randomly into two groups of 15 people each: one group gets standard Western heart medicine only, and the other gets standard Western heart medicine plus Yiyang Huoluo Decoction (herbal granules) * Complete the 12-week decoction treatment plan as directed by the research team * Attend scheduled study visits for health checks, blood tests, heart and blood vessel scans (such as carotid ultrasound and coronary CTA), and symptom reviews * Provide two small blood samples for research testing (samples will be destroyed after study testing is finished) * Report any side effects, discomfort, or changes in health to the research team right away All personal health information collected for this study will be kept private and confidential. Participation is completely voluntary, and participants may quit the study at any time for any reason without losing access to regular medical care.
NCT07485985
Refractory angina due to advanced obstructive coronary artery disease (CAD) remains a major clinical problem with limited evidence-based treatment options. The coronary sinus reducer (CSR) is an hourglass-shaped stainless-steel mesh device designed to create a controlled narrowing of the coronary sinus (CS). By increasing CS pressure, CSR implantation may improve myocardial perfusion and reduce anginal symptoms, although the physiological mechanisms underlying this effect remain incompletely understood. REDUCE-ANGINA is a prospective observational study investigating the hemodynamic effects of CSR implantation in 25 patients with refractory angina and advanced CAD. The study evaluates the interaction between coronary sinus hemodynamics and coronary arterial blood flow before and after CSR implantation. The main study endpoints include changes in coronary sinus pressure, coronary flow reserve, microvascular resistance reserve, and absolute microvascular resistance from baseline to 6 months, measured using continuous flow thermodilution during saline-induced coronary hyperemia.
NCT03854071
Physiological cardiovascular stress test plays a crucial role in the assessment of patients with suspected heart disease. There are several methods of cardiac physiological stress tests and each of them offer varied insight into cardiac physiological adaptation: passive leg raise, intra-venous fluid challenge, pharmacological stressors and physical exercise stress test. Echocardiography, which is the mainstay for the non-invasive rest/stress assessment of the left ventricular (LV) haemodynamics has several limitations. Novel methods of CMR imaging allow to map intra-cardiac flow in three-dimension using novel flow acquisitions. These novel flow acquisitions are called four-dimensional flow CMR, where the fourth dimension is time. Additionally, traditional cine CMR imaging for functional assessment can now be done without breath-holds using advanced acceleration methods, allowing them to be used during exercise. A comprehensive understanding of functional-flow coupling at rest, during increased pre-load (fluid challenge) to the heart or during exercise, is lacking in the literature. There is an important need to validate these novel CMR methods for developing mechanistic insight into physiological cardiac adaptation to increased pre-load or to exercise in health and how it alters in heart disease.
NCT07473596
The goal of this clinical trial is to describe the long-term (≥ 3 years) patency of coronary artery stents following chronic total occlusion percutaneous coronary intervention (CTO PCI). The main questions it aims to answer are: * What is the incidence of in-stent restenosis after CTO PCI? * What are patient-, lesion-, and procedure-related factors associated with an increased risk of in-stent restenosis after CTO PCI?
NCT07475273
Percutaneous Coronary Intervention (PCI) is a common revascularization procedure for patients with coronary artery disease. Patients undergoing PCI are often required to remain in a supine position for several hours after the procedure to prevent complications at the vascular access site. Prolonged immobilization can lead to discomfort and back pain. Early mobilisation may help reduce back pain and improve patient comfort without increasing the risk of complications. This study aims to evaluate the effectiveness of early mobilisation in reducing back pain among patients following Percutaneous Coronary Intervention.
NCT05081999
Patients with heart disease are often prescribed many medications and these patients may experience drug interactions or negative drug related side effects. With newer medications and treatments available, it is not well known whether older drugs, such as beta-blockers, are still an effective and safe option for treating heart disease. Some evidence suggests beta-blockers should be continued, whereas other evidence suggests beta-blockers might cause unnecessary harm. The study hopes to determine whether continuation or discontinuation of beta-blockers will affect long term cardiovascular outcomes. The study investigators will also examine how beta-blockers continuation or discontinuation affects several quality of life measures.
NCT07468955
Objective: This study aimed to retrospectively evaluate the impact of cardiac rehabilitation (CR) on functional capacity, depressive symptoms, and the quality of life and sleep in patients with heart disease. Methods: A retrospective analysis was conducted on patients who participated in a structured CR program. Clinical records were reviewed to compare pre- and post-rehabilitation outcomes. Functional capacity was assessed using the 6-Minute Walk Test (6MWT), while depressive symptoms, health-related quality of life, and sleep quality were evaluated using the Beck Depression Inventory (BDI), the Short Form-36 (SF-36), and the Pittsburgh Sleep Quality Index (PSQI), respectively.
