Active clinical trials for "Coronary Artery Disease"

South Asian (Indian, Pakistani, Bangladeshi, Nepali, and Sri Lankan) individuals have high rates of cardiovascular disease that is not explained by traditional cardiovascular risk factors. Though South Asians represent over one-quarter of the world's population, there are no longitudinal studies in this high-risk ethnic group. The investigators aim to establish a longitudinal study of South Asians at three United States centers to identify risk factors linked to subclinical atherosclerosis and incident cardiovascular disease. The purpose of this study is to understand the causes of heart disease and stroke in South Asians and compare these causes to those in other United States ethnic groups.

Chronic kidney disease (CKD) affects 10-18% of the adult population and is becoming recognized as one of the most serious disorders causing increased risk for cardiovascular disease and death. In patients with ischemic heart disease 26% have increased creatinine, which rises to 40% if patients also have diabetes mellitus. Risk increases as renal function diminishes, and just slowing the rate of decline in renal function would have a tremendous impact on health and morbidity. This association is commonly termed the Cardiorenal Syndrome, though it is caused by a much more complex interplay between major pathogenetic pathways such as glucose metabolism and diabetes, systemic and tissue inflammation, tissue metabolism, coagulation, mineral metabolism, sympathetic activation, renin-angiotensin-aldosterone system activation, endothelial dysfunction, lipid metabolism, fetal programming etc. Karolinska Institutet recently merged basic and clinical researchers in all these fields, creating a Karolinska Kardiorenal Theme Centre; ultimately aiming to explore the syndrome and provide improved care for the individual patient. The investigators road to success: Creating a Biobank (blood, DNA, plasma) from the majority of all hosptalized patients with ACS in Stockholm county - Stockholmheartbank. This Theme Center include all teaching hospitals associated with Karolinska Institutet; Danderyd University Hospital, Karolinska University Hospital and Södersjukhuset University Hospital. Together theses hospitals serve as emergency hospitals for 1.9 million people. The investigators are aiming at creating a biobank from all patients admitted for an acute coronary event (about 2.300/yr), which is a unique asset for molecular and genetic research as well as observational and intervention studies. The investigators have access to the National registry with 100% coverage, that contains data on all patients admitted to Stockholms coronary care units since 1995. To ensure translation in to clinical practice, most of the researchers are also MD:s, and several are clinically active. The clinical network facilitates the development of novel therapies and translational research. Steering groups for Education and a Clinical Practice implementation program.

About 15,000 patients with FFR (Fractional Flow Reserve) will be enrolled and evaluated for the natural history of coronary lesions at 2 years clinical and imaging follow-up.

The purpose of this study is to determine whether intensive blood pressure and low density lipoprotein (LDL) cholesterol lowering could improve survival and cardiovascular outcome in Japanese diabetic patients with coronary artery disease and history of acute coronary syndrome.

The study will compare standard ultrasound images to high frame rate ultrasound images in patients with heart disease or with a low risk of heart disease to see if a higher frame rate of ultrasound adds to the information obtained from standard ultrasound.

In patients after myocardial infarction (MI) (heart attacks) and treated with percutaneous coronary intervention (PCI), the current standard is dual antiplatelet therapy (DAPT), with aspirin and a P2Y12 receptor inhibitor, for 1 year of treatment. At 1 year, there are several options including: i) Ongoing DAPT (with aspirin and ticagrelor), ii) Selective treatment use of a P2Y12 inhibitor based on risk profiles. This study is a pilot vanguard study to evaluate several strategies for choosing anti-platelet regimen among patients post MI and PCI at 1 year.

Patients with coronary artery disease, especially after PCI, require long-term oral antiplatelet therapy. However, this patient population may inevitably require non-cardiac surgery for a variety of conditions. In order to avoid the occurrence of bleeding events, oral antiplatelet agents are usually discontinued before non-cardiac surgery in patients with coronary artery disease, which may increase the incidence of ischemic events. Therefore, it is important to provide patients with the optimal perioperative antithrombotic treatment to balance the risk of bleeding and ischemia.

The registry aims to follow clinically all consecutive patients treated by percutaneous coronary interventions at hospital & university Fribourg.

Heart diseases known as the second cause of death in Koreans are coronary artery diseases such as angina and myocardial infarction. Coronary artery disease occurs when fat components, such as cholesterol, accumulate in the body. When these fat components are deposited in blood vessels, blood vessels' walls become thick, and the blood vessels narrow, which interferes with circulation. Without smooth circulation, the heart muscle does not function properly because the supply of oxygen and nutrient-rich blood, which is necessary for the heart to function normally, is not properly supplied. It leads to angina pectoris and chest pain and can cause myocardial infarction or even heart attack. Coronary artery disease in various aspects has a high mortality rate when it occurs in old age. The methods currently used for diagnosis and treatment are coronary angiography, percutaneous coronary intervention (PCI), and myocardial partial blood flow reserve history. There is a wide variety of tests (Fractional Flow Reserve, FFR), near-infrared spectroscopy intravascular ultrasound (NIRS-IVUS). In addition to the various aspects and treatment methods of this disease, treatment is often difficult, so the clinical significance is great. In the case of PCI, one of the methods of examination and treatment, the National Cardiovascular Data Registry (NCDR) has been established to establish guidelines for improving patient prognosis after surgery in the United States. NCDR, which started with the American College of Cardiology (ACC) initiative, is currently in an indispensable position for establishing clinical practice guidelines such as monitoring treatment-related indicators, quality improvement (QI), and clinical research. In charge. Besides, in recent years, the use of new drugs or new devices (Post-Market Surveillance), real-time risk estimation, and personalized planning is increasing. Research to analyze the prognosis of various aspects of coronary artery disease, tests, and procedures has been constantly conducted, but comprehensive studies that can be used to improve the overall treatment are considered to be insufficient. At this point, a comprehensive study is required to establish clinical guidelines and to develop them continuously. In particular, the area that needs research is whether or not future events can be prevented using vascular imaging. Studies have shown that if lipids are actively treated with statins, the lipid component of atherosclerotic plaques can be significantly reduced in just a few weeks. Suggests. According to the results of a YELLOW (Reduction in Yellow Plaque by Aggressive Lipid-Lowering Therapy) study published in 2012 based on a near-infrared spectroscopy-vascular ultrasound analysis, the active treatment group of statins showed the lipid-core burden index compared to the standard treatment group. ) showed a significant decrease. Accordingly, this study collects all comprehensive indicators such as test methods, test results, procedures, and treatment results for all patients undergoing near-infrared spectroscopy-vascular ultrasound treatment in Korea, including this institution, A comprehensive study of the disease registry related to the near-infrared spectroscopy-vascular ultrasound procedure is conducted to determine the type of disease, the number of affected vessels, and disease-related indicators.

CONCORD is a prospective observational study evaluating the diagnostic accuracy of cardiovascular magnetic resonance (CMR) and computed tomography with fractional flow reserve (CT-FFR) in patients with suspected coronary artery disease, using invasive fractional flow reserve (FFR) as the reference standard.
