Active clinical trials for "Myocardial Ischemia"

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 extend mortality followup through 25 years for two cohorts of men in the Multiple Risk Factor intervention Trial (MRFIT): the 361,662 men screened and the 12,866 men randomized, and to pursue the general aim of elucidating unresolved research issues on the epidemiology, natural history, etiology, prevention, and control of major chronic diseases, particularly cardiovascular and neoplastic diseases and diabetes.

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.

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

Registry of patients undergoing invasive fractional flow reserve measurement using a motorized device.

This study aims to evaluate the psychometric properties of a newly developed FFQ specified for northern Chinese CHD and their high risk patients (CHD-FFQ). The psychometric properties include test-retest reliability, content validity, convergent validity, discriminant validity, concurrent validity and predictive validity. Particularly, this study will measure the physiological indicators, including plasma lipid profile (i.e. TG, TC, HDL-C, LDL-C), BG, BP and BMI twice at baseline and the end. The level of these physiological indicators will be compared with the fat intake measured by the CHD-FFQ, i.e. the baseline intake to test its convergent validity. It is also expected to predict the diet-related progression of CHD risks among high-risk individuals, i.e. patients with two or more CHD risk factors as following: raised fasting blood glucose (BG) level, increased blood pressure (BP), increased triglycerides (TG), decreased HDL-Cholesterol (HDL-C), increased LDL-Cholesterol (LDL-C), smoking and central obesity (International Diabetes Federation, 2015). In addition, this study will provide the FFQ's concurrent validity in assessing the intake of energy and nutrients against the CDC-FFQ. Moreover, whether the FFQ could detect the known differences in energy intake between men and women will be established for its discriminant validity.

A prospective analytic study to evaluate the incidence, clinical and laboratory characteristics, extent of coronary artery disease and short-term outcome of newly diagnosed diabetes and pre-diabetes in patients with first-time diagnosed coronary artery disease treated in Saud Al Babtain Cardiac Center.

The development of coronary artery disease is multifactorial. Peripheral blood biomarkers paly an important role in the prediction of coronary artery disease. However, the identification of those biomarkers and their correlation with the presence and severity of coronary artery disease are unclear. The present study aims to identify the differentially expressed biomarkers from peripheral blood between normal population and patients with different disease burden confirmed by coronary angiography, and to analyze the correlation of those biomarkers with the severity of coronary artery disease. Finally, the prediction of biomarkers for clinical events.

This trial is designed to associate angiography-based fractional flow reserve (3D-angio-based FFR) values with optical coherence tomography findings in pre- and post-percutaneous coronary intervention in patients with non-ST segment elevation acute coronary syndromes.
