SUMMARY Whole-body venous capacity was examined in conscious 4-roonth-old male spontaneously hypertensive rats (SHR) and Wlstar-Kyoto normotensive (WKY) rats by determining mean circulatory Ailing pressure (MCFP) and blood volume. The MCFP was determined in conscious animals after briefly arresting the circulation by inflating an indwelling balloon in the right atrium. Blood volume was determined by dilution of "M-albumin and "Cr-red cells. Although blood volume was not significantly different between SHR (60.9 ± 0.7 ml/kg, SE) and WKY (59.6 ± 0.8 ml/kg), MCFP was slightly, but significantly elevated in the SHR (

The PRICE-1 conference was designed to identify near term priorities for funding cardiovascular research in the elderly. Twenty topics were identified with either break throughs in fundamental mechanisms of aging with cardiovascular systems or with critical importaance to cardiovascular carve of the elderly.
