To evaluate benefits of primary prevention of major coronary heart disease for asymptomatic coronary artery disease in type 2 diabetes mellitus based on the coronary artery calcium score Our proposal 1. Based on CAC score, primary early prevention could reduce incidence of major coronary heart disease (CHD) including cardiac mortality, acute myocardial infarction, coronary revascularization 2. based on CAC score, primary early prevention could reduce all cause mortality, cardiac mortality, cardiovascular disease, heart failure, ischemic stroke, heart failure associated hospitalization and chronic kidney disease and related clinical cost effect
According to the Women's Ischemic Syndrome Evaluation database, there are approximately 3 to 4 million women and men who present with signs and symptoms that are suggestive of myocardial ischemia, however they have no obstructive coronary artery disease (INOCA). INOCA is defined as patients presenting with signs or symptoms of ischemia but no obstructive artery disease. Women are more likely than men to die from cardiovascular disease and more likely to present with no obstructive coronary artery disease. Patients who present with signs and symptoms suggestive of INOCA/MINOCA are also presenting with Coronary Microvascular Dysfunction (CMD). Coronary Microvascular Dysfunction is a dysfunction in the epicardial and/or microvascular endothelial and/or nonendothelial that limits myocardial perfusion. Today, there is no routinely offered/available noninvasive test that is used for the diagnosis of CMD, significantly hindering the ability to identify the disease in the standard of care. Magenetocardiography (MCG) has the opportunity to use its noninvasive imaging techniques to provide early management of CMD. Magnetocardiography (MCG) is a noninvasive imaging modality that has been extensively studied, over the past several decades, as a diagnostic imaging solution for various forms of cardiovascular disease. MCG measures the magnetic field that arises from the electrical activity of the heart's pacemaker activity, the very same activity which yield surface electric field potentials as measured by the electrocardiogram. Since MCG is a functional assessor of repolarization heterogeneity, it is hypothesized that MCG may be a useful frontline diagnostic to identify CMD in patients who would otherwise have normal coronary CT angiograms and/or stress tests. The proposed study intends to study the diagnostic accuracy of MCG in this population, with the goal of providing early and noninvasive insights for management of CMD. There will be a 12-month duration of the study where the investigators propose to collect MCG scans from approximately 150 patients who present to the Genetesis facility for a 15-minute CardioFlux scan appointment.
This is a multi-center, prospective and controlled clinical trial which will enroll 200 coronary arteriography or percutaneous coronary intervention with 2-4 interventional cardiologist. The interventional cardiologist performed 100 interventional procedures using either a new protective device (NPD) or a traditional lead clothing (TLC). The cumulative dose outside the NPD or TLC and the first operator at each height (110cm, 90cm, 50cm, 10cm) was measured. The main indicators of the study are the average X-ray shielding efficiency of the NPD and the TLC at four different heights. The investigators will record all operation information in this study.
The investigators are conducting a randomized clinical trial, having as a primary objective, to compare vascular access time between distal and proximal radial approach. Secondary objectives include comparing incidence of distal and proximal radial artery occlusion, at 24 hrs and 30 days. As a tertiary objective investigators will compare the preference of the patients for each access in subsecuent interventional procedures.
The purpose of this research is to see if Heart Health Yoga (HHY) Program when added on to standard cardiac rehabilitation (CR) will improve overall wellbeing and quality of life for patients experiencing ischemic heart disease, heart problems caused by narrowed heart arteries.
In a prospective multi-center observational study, 200 HIV-infected patients treated with antiretroviral treatment (ART) and who suffered from coronary artery disease (CAD) will be enrolled. Blood samples for biological parameters will be collected with all participants: lipid profile and markers of systemic inflammation specific for HIV-infection (lipopolysaccharide-binding protein; cytokines: IL-1β, IL-6, IL-8, IL-10, TNF -α, INF-γ, INF-α; procalcitonin; inflammatory hsCRP). All of them will undergo functional testing (Echo, CMR both at rest and stress if necessary) and invasive imaging with QCA, FFR, QFR, OCT, IVUS, VH-IVUS, NIRS. Patients will be treated according to the current and previous recommendations. Both medical treatment and percutaneous transluminal coronary angioplasty (PTCA) with or without stenting will be done. Collected data will be analyzed: correlation between ART, blood test results, coronary angiography results, including performed PTCA, history of myocardial infarctions, and other cardiovascular events. The follow-up period will achieve 12 months prospectively with collected clinical events and imaging outcomes which will be determined at the baseline and 12-month follow-up. The independent ethics expertise will be provided by the Central Clinical Hospital of the Russian Academy of Sciences (Moscow, Russia). The monitoring of the clinical data with imaging will be provided by The Ethics Board of Central Clinical Hospital of the Russian Academy of Sciences.
The purpose of this study is to evaluate the safety and efficacy of Genoss® DCB by demonstrating non-inferiority in patients with in-stent restenosis (ISR) compared with a product of the same category (Sequent® Please NEO). The experimental group was treated with Genoss® DCB, and the control group was treated with SeQuent® Please NEO. In this study, the end point of 9 months after procedure was used as the main endpoint to evaluate the efficacy of Paclitaxel coated PTCA balloon catheter. The safety of the catheter was evaluated by cardiovascular adverse events.
The purpose of this study is to investigate the safety and efficacy of drug-coated balloon angioplasty for the treatment of chronic total occlusions patients with chronic total occlusion (CTO) lesion.
Early-Synergy investigates a diagnostic imaging approach in asymptomatic individuals from the general population for early detection of silent myocardial ischemia and cardiac dysfunction. The diagnostic imaging approach consists of cardiac computed tomography for coronary artery calcium scoring (CT-CAC) and cardiac magnetic resonance (CMR) stress perfusion imaging. Early-Synergy investigates the effect of early detection of silent myocardial ischemia and cardiac dysfunction by CMR in asymptomatic individuals with increased CAC. In addition, the diagnostic yield of CMR for early detection of silent myocardial ischemia and cardiac dysfunction is investigated. Asymptomatic individuals at increased risk (CAC ≥ 300) are therefore randomized 1:1 to either CMR stress perfusion imaging or a control group.
