We review the Finapres technology, embodied in several TNO-prototypes and in the Ohmeda 2300 and 2300e Finapres NIBP. Finapres is an acronym for FINger Arterial PRESsure, the device delivers a continuous finger arterial pressure waveform. Many papers report on the accuracy of the device in comparison with intra-arterial or with noninvasive but intermittent(More)
OBJECTIVE To assess the effect of prenatal exposure to maternal malnutrition on coronary heart disease in people born around the time of the Dutch famine, 1944-45. DESIGN Historical cohort study. SETTING Community study. PATIENTS Singletons born alive between November 1943 and February 1947 for whom detailed birth records were available. DESIGN The(More)
BACKGROUND Little is known about the efficacy and safety of renal artery stenting in patients with atherosclerotic renal artery stenosis (ARAS) and impaired renal function. OBJECTIVE To determine the efficacy and safety of stent placement in patients with ARAS and impaired renal function. DESIGN Randomized clinical trial. Randomization was centralized(More)
BACKGROUND Many studies have shown that low birth weight is associated with high blood pressure. The composition of the diet of pregnant women has also been found to affect blood pressure in their children. We assessed the effect of prenatal exposure to the Dutch famine of 1944-1945, during which the caloric intake from protein, fat and carbohydrate was(More)
OBJECTIVE To determine the long term effects of relaxation therapy on 24 hour ambulatory intra-arterial blood pressure in patients with mild untreated and uncomplicated hypertension. DESIGN Four week screening period followed by randomisation to receive either relaxation therapy or non-specific counselling for one year. Ambulatory intra-arterial blood(More)
The influence of supine rest on the blood pressure response to standing and 70 degrees head-up tilt was studied in detail for the first 30 s after the change of posture. Following 20 min of supine rest, the active transition to standing was accompanied by an immediate increase in systolic pressure of 29 +/- 6 mmHg (mean +/- SEM). This was followed by large(More)
OBJECTIVES To investigate whether exercise-induced hypertension in successfully repaired adult post-coarctectomy patients is associated with hypertension on 24-h blood pressure measurement and increased left ventricular mass. METHODS One hundred and forty-four consecutive post-coarctectomy patients (mean age 31.5 years, range 17-74 years; mean age at(More)
We determined the continuous 24-hour profile of mean arterial pressure, heart rate, stroke volume, cardiac output, and total peripheral resistance in eight healthy ambulatory volunteers. Beat-to-beat intra-arterial blood pressure was recorded with the Oxford system; subjects were ambulant during daytime and slept at night. Beat-to-beat stroke volume was(More)
The objective of this study was to determine the effect of aging on beat-to-beat blood pressure and pulse interval variability in resting conditions and to determine the effect of aging on the sympathetic and vagal influence on the cardiovascular system by power spectral analysis of blood pressure and pulse interval. We studied three groups of healthy,(More)
BACKGROUND AND PURPOSE We addressed whether dynamic cerebral autoregulation (dCA) is affected in middle cerebral artery (MCA) territory (MCAS) and lacunar ischemic stroke (LS). METHODS Blood pressure (MAP) and MCA velocity (V) were measured in 10 patients with large MCAS (National Institutes of Health Stroke score, 17+/-2; mean+/-SEM), in 10 with LS(More)
