STUDY OBJECTIVE To evaluate the impact of gender on labetalol kinetics. DESIGN Part of a randomized, crossover study. SETTING Academic medical center. PATIENTS Nineteen hypertensive patients (14 men, 5 women; 6 blacks, 13 whites). INTERVENTIONS Participants had labetalol dosages titrated to a specific antihypertensive response, then underwent(More)
The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of cangrelor administered as an intravenous bolus plus a continuous infusion in healthy volunteers. Twenty-two healthy volunteers are randomized to receive 1 of 2 intravenous cangrelor dosing regimens: a 15-microg/kg bolus followed by a 2-microg/kg/min(More)
BACKGROUND Cangrelor is a direct, parenteral, and reversible inhibitor of the platelet P2Y12 receptor currently undergoing Phase III testing. As many individuals treated acutely with cangrelor will often be treated long-term with a thienopyridine, it is important to determine the effects of concurrent cangrelor and clopidogrel administration. METHODS AND(More)
STUDY OBJECTIVE To investigate the effects of the angiotensin II subtype 1 receptor (AT1R) antagonist losartan on functional recovery of isolated rat hearts undergoing global myocardial ischemia-reperfusion compared with myocardial protective effects of ischemic preconditioning. DESIGN Ex vivo experiment using isolated perfused rat heart. SETTING(More)
OBJECTIVE To determine whether obesity-induced hypertension was associated with alterations in vascular contractility and/or cardiac function. DESIGN Male Sprague-Dawley rats were fed either a low fat (LF; 11% kcal as fat) or a moderately high fat (MHF; 32% kcal as fat) diet for 11 weeks. MEASUREMENTS Body weight; mean arterial pressure; angiotensin(More)
Angiotensin II and norepinephrine (NE) have been implicated in the neurohumoral response to pressure overload and the development of left ventricular hypertrophy. The purpose of this study was to determine the temporal sequence for activation of the renin-angiotensin and sympathetic nervous systems in the rat after 3-60 days of pressure overload induced by(More)
INTRODUCTION Previous work suggests that the extent of platelet inhibition by P2Y(1) receptor antagonism may be underappreciated, particularly in the context of dual antiplatelet therapy with aspirin and clopidogrel. MATERIALS AND METHODS Using P2Y(1), P2Y(12), and TxA(2) receptor antagonists individually and in combination, we assessed the incremental(More)
A 56-year-old man with heparin-induced thrombocytopenia with thrombosis syndrome (HITTS) received anticoagulation with recombinant hirudin (lepirudin) for emergency coronary artery bypass graft (CABG) surgery and aortic valve replacement. The patient experienced life-threatening refractory bleeding that was successfully treated with recombinant factor VIIa.(More)
BACKGROUND Lifestyle modification and appropriate medical therapy improve long-term outcomes following coronary artery bypass grafting (CABG). Our institutional experience suggested that evidence-based recommendations were not being followed postdischarge after CABG. We undertook this study to document our rate of compliance with evidence-based guidelines(More)
