Active clinical trials for "Coronary Artery Disease"

To evaluate the relation of retinal microvascular characteristics to subclinical cardiovascular disease, clinical disease, and their risk factors in the Multi-Ethnic Study of Atherosclerosis (MESA) cohort.

This study will examine the health-related quality of life in patients being treated for chronic heart disease. Patients 18 years or older with chronic ischemic heart disease and left ventricular dysfunction enrolled in protocols in the National Heart Lung and Blood Institute's Cardiology Branch may participate in this study. Participants will complete five questionnaires at 3 separate times during the study-once during hospitalization at the NIH Clinical Center and again at home 6 months and 1 year later. The questionnaires, described below, require a total of about 30 minutes to complete. Demographic Information Sheet -General information such as age, marital status, employment, education, and history of cardiac medical procedures. General Health Survey -Patient's self-assessment, on a rating scale, of physical and emotional well being. Questions are related to the ability to perform work and daily living activities, mood and state of mind, limitations on social activities, energy level, pain level, general quality of life, etc. Heart Disease Survey - Patient's self-assessment, on a rating scale, of the level of physical, social, emotional and functional well being related to his or her heart condition. Questions concern fatigue level, emotional outlook, social well being, etc. Angina Survey - Information on the frequency of chest pain, chest tightness, or angina. Symptom Distress Survey - Patient's ranking of the degree of symptom distress from chest discomfort, difficulty breathing, heart rate irregularities, wheezing and coughing. All information provided in the questionnaires will be kept confidential. Upon request, patients will be sent a summary of the study results when the study is completed.

To study the entire population of Olmsted County, Minnesota, including all age categories, to examine the secular trends in coronary heart disease (CHD) mortality, myocardial infarction (MI) incidence, and natural history, including MI severity, case fatality and post-MI morbidity. Also, to examine the time trends in the prevalence of CHD at post-mortem because of the uniquely high autopsy rate in Olmsted County.

EUROASPIRE is a multicentre European study in coronary patients and individuals at high risk of developing cardiovascular disease (CVD), describing their management through lifestyle and use of drug therapies and providing an objective assessment of clinical implementation of current scientific knowledge. Four EUROASPIRE surveys have been carried out by the European Society of Cardiology so far: EUROASPIRE I in 1995-1997 in nine countries, EUROASPIRE II in 1999- 2000 in 15 countries, EUROASPIRE III in 2006-2009 in 22 countries and EUROASPIRE IV in 2012-2015 in 26 countries. The results showed a wide gap between the recommendations and clinical practice with many patients not achieving the lifestyle and medical risk factors goals for CVD prevention. The fifth EUROASPIRE survey is planned for 2016-2018 to determine in hospital coronary patients and apparently healthy individuals in primary care at high risk of developing cardiovascular disease whether the European and national guidelines on cardiovascular disease prevention have been followed and if the practice of preventive cardiology in EUROASPIRE IV has improved by comparison with those centres which took part in EUROASPIRE I, II, III and IV. This survey will also incorporate an assessment of dysglycaemia and kidney function in all patients. The main outcome measures will be the proportions of coronary and high cardiovascular risk patients achieving the lifestyle, risk factor and therapeutic targets for cardiovascular disease prevention. The data collection will be based on a review of patient medical records and a patient interview and examination at least 6 months and at most 3 years after recruiting event. All countries which participated in the first three surveys will be invited to take part in EUROASPIRE V. This fifth survey will give a unique picture of preventive action by cardiologists and primary care physicians looking after patients with coronary disease and individuals at high CVD risk.

Assess the relationship of Aortic root distensibility and stiffness with the extent of coronary artery disease as assessed by SYNTAX score compared to a matched cohort of patients with normal coronary angiography

For permanent coronary stents, reduction of thickness of struts have become one of the most important innovation, being related to easier manipulation, reduced risk of stent thrombosis and low rate of revascularization. Consequently the investigators performed a multicenter registry enrolling all consecutive patients treated with very thin stents for ULM or bifurcation.

The investigators sought to investigate the prognostic implication of qualitative and quantitative plaque analysis on coronary CT angiography (CCTA) according to fractional flow reserve (FFR). The main objective was to develop a comprehensive risk model by using clinical risk factors, FFR and CCTA parameters.

The Multicenter FAST (Fast Assessment of STenosis severity) study is a prospective observational multicenter study designed to evaluate the diagnostic accuracy of offline 3D-QCA based FFR, using CAAS Workstation (Pie Medical Imaging, Maastricht, the Netherlands) in identifying hemodynamically significant coronary artery disease with pressure wire-based FFR (≤0.80) as the reference standard.
