OBJECTIVE To study long-term treatment effects of metoprolol or verapamil on combined cardiovascular end points and psychological variables in patients with stable angina pectoris. DESIGN Randomized, double-blind, double-dummy trial. PATIENTS The study included 809 patients under 70 years of age with stable angina pectoris. The mean age of the patients(More)
We report here a simple method involving urine creatine measurements for testing authenticity and reducing false-negative results in urine testing for drugs of abuse. Urinary creatinine in consecutive patient samples (n = 176) ranged between 0.1 and 31.9 mmol/L (mean 9.8 +/- SD 6.2) and the osmolality in these urines ranged between 49 and 1183 mOsm/kg (mean(More)
Atherosclerosis is an inflammatory and thrombotic disease. Both platelets and lymphocytes play important roles in atherogenesis. However, information on their interaction is limited. We therefore studied how platelets regulate CD4+ T cell activation and differentiation. Human CD4+ T cells and autologous platelets were co-cultured. Platelets(More)
Experimental models have indicated prothrombotic effects of inhibition of nitric oxide (NO) production, and anti-thrombotic effects of inhaled NO, but the influence of NO on platelet function in vivo in humans is not well established. We therefore investigated the effects of systemic inhibition of NO synthesis by N(G)-monomethyl-L-arginine (L-NMMA) and of(More)
1 Cardiovascular and sympatho-adrenal responsiveness to mental stress (CWT; a colour word test), orthostatic testing (ORT) and a cold pressor test (CPT) were examined in three groups of hypertensive patients (n = 14-16) before and after 6 months treatment with metoprolol (243 +/- 26 mg daily), propranolol (149 +/- 16 mg daily) or hydrochlorothiazide (50 +/-(More)
BACKGROUND Platelet-leukocyte aggregates (PLAs) may be important in thrombotic and inflammatory disease states, but accurate assessment of PLA formation in vivo is hampered by the propensity for in vitro artefacts caused by sample manipulation. A whole blood flow cytometric assay for circulating PLAs, based on minimal sample manipulation, was thus(More)
1. The influence of circulating 5-hydroxytryptamine (serotonin) on small intestinal motility was investigated in healthy volunteers. 2. Small intestinal motility was studied by means of a constantly perfused multi-channel manometry tube, connected to a computer system. 3. Intravenous infusions of either 5-hydroxytryptamine at increasing doses or saline were(More)
INTRODUCTION The oral direct thrombin inhibitor dabigatran is increasingly used to prevent thromboembolic stroke in patients with atrial fibrillation (AF). Routine laboratory monitoring is currently not recommended, but measurements of dabigatran and/or its effect are desirable in certain situations. We studied dabigatran exposure and compared different(More)
Patients with pregnancy-induced hypertension (PIH) and healthy pregnant and non-pregnant women were compared with regard to cardiovascular responses to i.v. infusions of noradrenaline (NA) and adrenaline (ADR). This resulted in physiologically relevant concentrations in arterial plasma (maximally 10 nmol/litre for NA and 6 nmol/litre for ADR). Non-pregnant(More)
