Pulse pressure, the difference between systolic and diastolic blood pressure, is an independent risk factor for cardiovascular disease. Increased pulse pressure reflects reduced compliance of arteries and is a marker of atherosclerosis. To locate genes that affect pulse pressure, a genome-wide linkage scan for quantitative trait loci influencing pulse pressure was performed using variance compo...
BACKGROUND The accuracy of the central aortic systolic (SBP-C) and pulse (PP-C) blood pressures estimated noninvasively by a generalized transfer function technique has been questioned. The purpose of the present study was to quantify precisely the impact of the input errors (differences between the oscillometric (SBP-O, DBP-O, PP-O) and invasive (SBP-B, DBP-B, PP-B) brachial systolic, diastoli...
BACKGROUND Automatic noninvasive oscillometric blood pressure (NIBP) devices measure mean arterial (MAP); systolic and diastolic (SBP, DBP) are algorithmically derived from MAP. The most invalid NIBP is SBP, yet stroke practitioners use it to manage (BP) in accordance with thrombolysis guidelines. We determined agreement between DBP, MAP measured manually by patients treated alteplase. METHODS ...
BACKGROUND Ambulatory blood pressure is more closely correlated with various indices of hypertensive target-organ damage, and is a better prognostic predictor of cardiovascular morbidity and mortality than conventional methods of blood pressure measurement. Autosomal dominant polycystic kidney disease (ADPKD) is complicated by hypertension, progressive renal failure, and an increased risk of ca...
An intelligent system for continuous blood pressure monitoring on remote multi-patients in real time
In this paper we present an electronic system to perform a non-invasive measurement of the blood pressure based on the oscillometric method, which does not suffer from the limitations of the well-known auscultatory one. Moreover the proposed system is able to evaluate both the systolic and diastolic blood pressure values and makes use of a microcontroller and a Sallen-Key active filter. With re...
