Filter by:To measure associations of established and suspected coronary heart disease risk factors with both atherosclerosis and new coronary heart disease events in representative cohorts from four diverse United States communities. To compare the communities with respect to risk factors, medical care, atherosclerosis, and coronary heart disease incidence. ARIC has two components in each community: study of representative cohorts of adult men and women, and community surveillance of morbidity and mortality.
To measure changes in coronary heart disease risk factors in cohorts of Black and white males and females 18 to 30 years of age at baseline. Also, to identify life styles during this age span which influence these changes in risk factors.
To conduct epidemiologic surveys of the distribution, causes, and consequences of the dyslipoproteinemias. The Population Studies include the Prevalence Study, the Family Study, and the Mortality Follow-up Study and shared the same general population base.
To conduct longitudinal and cross-sectional studies of risk factors for coronary heart disease and hypertension in school age children and adults who had been examined in previous screens.
To continue a registry of World War II veteran twins maintained by the National Academy of Sciences-National Research Council (NAS-NRC).
To assess genetic effects on the variation of cardiovascular and pulmonary risk factors in a cohort of 514 pairs of white male veteran twins.
To investigate coronary heart disease and stroke among American men of Japanese ancestry who were living on the island of Oahu in 1965. Morbidity and mortality surveillance of the original cohort is continuing.
To conduct surveillance of cardiovascular morbidity and mortality and its correlation with known risk factors in all cohort study groups in Evans County, Georgia.
The Framingham Heart Study was initiated to study the factors associated with the development of cardiovascular disease by employing long-term surveillance of an adult population in Framingham, Massachusetts. The Framingham Offspring Study was initiated to assess familial and genetic factors as determinants of coronary heart disease.
This study will assess the value of magnetic resonance imaging (MRI) in detecting heart attack and heart attack risk in patients who come to the hospital emergency room because of chest pain. It will also investigate whether MRI can help predict the coronary status of patients 4 to 6 weeks and 1 year after emergency room admission. Patients who come to the emergency room of Suburban Hospital in Bethesda, MD, because of chest pain may be asked to enroll in this study if they have not been diagnosed as having a heart attack. Participating patients will undergo a MRI scan as soon as emergency room doctors determine they are in stable condition. For this procedure, the patient lies on a table that slides into the MRI scanner-a large tubular machine with a magnetic field. During the scan, a contrast material is injected into the vein. This material brightens the image of the heart so that the blood flow can be seen. The scan will show if there are areas of heart muscle that received insufficient blood flow. A second scan will be done within 72 hours to look for coronary artery blockage that may require treatment. Patients will be followed by telephone 4 to 8 weeks after the scans and again 1 year after the scans to ask about any significant medical problems that may have occurred during those time periods. This study will provide information that may improve emergency treatment of patients with acute chest pain by clarifying which patients require immediate medical treatment, which should be admitted to the hospital for further evaluation, and which may safely be discharged from the hospital.
