National Health and Nutrition Examination Survey IV (NHANES (IV)
Cardiovascular DiseasesCoronary Disease4 moreTo supplement the fourth National Health and Nutrition Examination Survey protocol to include data on the common heart, vascular, lung, and blood diseases.

Speech Characteristics in Coronary Heart Disease
Cardiovascular DiseasesHeart Diseases1 moreTo improve the predictive validity of Structured Interview assessments of Type A behavior by comparing interviewer techniques in the Multiple Risk Factor Intervention Trial (MRFIT) and the Western Collaborative Group Study (WCGS). To assess whether there were interviewer differences in the predictiveness of Type A behavior and its components for coronary heart disease incidence in MRFIT and WCGS and if so, to assess whether the interviewer differences in disease predictiveness were related to interviewer stylistics.

Epidemiology of Decline in Heart Disease Mortality
Cardiovascular DiseasesHeart Diseases1 moreTo continue a study of premature coronary heart disease mortality among men and women aged 35-54 in Allegheny County, Pennsylvania.

Coronary Calcification Progression Study
Cardiovascular DiseasesCoronary Disease1 moreTo investigate use of Fast Gated Helical Computed Tomography (FGHCT) measures of coronary artery calcium (CAC), FGHCT-CAC, for discrimination of coronary artery disease (CAD) and to quantify progression of coronary artery calcium over time.

Children's Activity and Nutrition III
Cardiovascular DiseasesHypertension1 moreTo track blood pressure from childhood through adolescence.

Evaluation of Patients With Known or Suspected Heart Disease
Peripheral Artery DiseaseCoronary Disease5 moreIn this study researchers will admit and evaluate patients with known or suspected heart disease referred to the Cardiology Branch of the National Heart, Lung, and Blood Institute (NHLBI). Patients participating in this study will undergo a general medical evaluation, including blood tests, urine, examination, chest x-ray and electrocardiogram (EKG). In addition, patients may be asked to have an echocardiogram (ultrasound scan of the heart) and to perform an exercise stress test. These tests are designed to assess the types and causes of patient's heart diseases and to determine if they can participate in other, specific research studies.

Non Obstructive Versus Obstructive Coronary Artery Disease
Non-Obstructive Coronary Artery DiseaseThe goal of this observational study is to study the non obstructive type of ischemic heart disease by identifying unique clinical features , frequency and age group .in patient admitted in coronary care unit , suffered from angina or heart attack. . The main question[s] it aims to answer are: how it different from classical type of ischemic heart disease ( obstructive coronary artery disease) what is frequency and age prevalence of these patient Participants evaluated by history , clinical examination, serum troponin and coronary angiography.

The FLUYDO NC Post Market Clinical Follow-up Study
Coronary Artery DiseaseCoronary Disease1 moreThe aim of the present observational study is to collect clinical data on the medical device non-implantable medical device Fluydo NC: coronary angioplasty non-compliant balloon dilatation catheter in the daily use in a not selected population.

Coronary Artery Disease Severity in Newly Diagnosed Dysglycemia
Coronary Artery DiseaseDysglycemiaThis cohort study will measure how severe is the coronary artery disease (CAD), at time of CAD diagnosis, clinically and angiographically in the different cohorts of newly diagnosed diabetes and prediabetes versus normal glycemia patients in the study center.

Optimization of 99mTc-Sestamibi Activities in SPECT/CT Myocardial Perfusion Imaging
Coronary Heart DiseaseThis work suggests a methodology to adapt the injected radionuclide activity to the level of attenuation of each patient. The investigators propose a dose reduction adapted to the patient's weight, with no significant degradation of the image quality, in order to improve patients and staff radioprotection, standardize the image quality for easier clinical interpretation, and lead to radiopharmaceutical saving in the context of myocardial perfusion Imaging.
