To study relationships among lipoprotein metabolism, hypertension, and hyperinsulinemia-insulin resistance in African American males and females. The study was part of a Collaborative Project on Minority Health which investigated the mechanisms by which insulin contributes to cardiovascular disease.
The study was part of the initiative "Collaborative Projects (R01s) on Minority Health". The concept for the initiative was developed by the NHLBI staff after the 1993 Report of the Committee on Appropriations, House of Representatives, encouraged the NHLBI to establish minority centers to facilitate the diagnosis and treatment of cardiovascular diseases. The initiative was approved at the September 1992 National Heart, Lung, and Blood Advisory Council and released in October 1992.
Julian Marsh was one of three investigators in a collaborative program with Bonita Falkner as Program Coordinator.
In a sub-set of subjects with either high or low plasma insulin levels after a glucose challenge (insulin sensitive or insulin resistant), the investigators determined the fractional and absolute synthesis and catabolic rates of apolipoproteins B and A-I, the dominant lipoproteins of Low Density Lipoprotein (LDL) and High Density Lipoprotein (HDL). They used stable isotopes and multicompartmental kinetic analysis following an oral bolus dose of deuteroleucine. They hypothesized that in hypertensive African Americans with hyperinsulinemia, more of the smaller Very Low Density (VLDL) particles are secreted and converted to LDL.

Unexpected rapid natural death due to cardiovascular collapse within one hour of initial symptoms. It is usually caused by the worsening of existing heart diseases. The sudden onset of symptoms, such as CHEST PAIN and CARDIAC ARRHYTHMIAS, particularly VENTRICULAR TACHYCARDIA, can lead to the loss of consciousness and cardiac arrest followed by biological death. (from Braunwald's Heart Disease: A Textbook of Cardiovascular Medicine, 7th ed., 2005)
Dental care for patients with chronic diseases. These diseases include chronic cardiovascular, endocrinologic, hematologic, immunologic, neoplastic, and renal diseases. The concept does not include dental care for the mentally or physically disabled which is DENTAL CARE FOR DISABLED.
Blood pressure levels that are between normotension and hypertension. Individuals with prehypertension are at a higher risk for developing cardiovascular diseases. Generally, prehypertension is defined as SYSTOLIC PRESSURE of 131-139 mm Hg and/or DIASTOLIC PRESSURE of 81-89 when the optimal is 120/80 mm Hg. For diabetics and other metabolism diseases the prehypertension is around 110-129/70-79 mm Hg.
