To conduct gene mapping studies for quantitative traits.
The study built upon existing sib-pair methods for multipoint mapping of Quantitative Trait Loci (QTL)s. It greatly expanded upon the statistical methodology to identify and localize QTLs for complex traits by merging sib-pair methods with a powerful twin design which used phenotypic data on monozygotic (identical) and dizygotic (fraternal) twins to resolve phenotypic variability into genetic and non-genetic components, and partition human quantitative genetic variation into effects due to loci on specific chromosomal regions. This quantitative methodology was applied to risk factors for cardiovascular disease -- one of the most pressing health problems in Western society. Population-based samples of Dutch, Swedish, and Australian twins had been identified in previous studies, phenotypic measures on lipids, lipoproteins, and other important cardiovascular risk factors had been obtained, and blood had been banked in a valuable resource which was available for use in this study. In 500 DZ twin pairs, a series of 175 highly polymorphic microsatellite markers were detected using an automated process for detecting fluorescent signals. These data were analyzed using the new statistical methods both to confirm the effects of a series of candidate loci and to test for the effects of previously unknown QTLs.

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.
