BACKGROUND The mechanisms involved in the dysfunction of both endothelium-dependent vasodilatation (EDV) and NO biosynthesis related to smoking are unclear. In this study, EDV was assessed in healthy smokers and nonsmokers in vivo and, using serum from the same individuals, was related to the NO biosynthetic pathway in vitro. METHODS AND RESULTS… (More)
OBJECTIVES The goal of this study was to investigate the dose-dependent effects of active cigarette smoking on endothelial nitric oxide (NO) and endothelin-1 (ET-1) biosynthesis. BACKGROUND Limited studies have suggested that active cigarette smoking may be associated with a dose-dependent reduction of endothelium-dependent vasodilation (EDV). The… (More)
OBJECTIVES The objective of this study was to evaluate the association of high plasma levels of either C-reactive protein (CRP), lipoprotein (a) (Lp[a]) or total homocysteine (tHCY) with the long-term prognosis after successful coronary stenting (CS). BACKGROUND High plasma levels of either CRP, Lp(a) or tHCY may have an impact in coronary artery disease.… (More)
BACKGROUND Our group has previously shown that human umbilical vein endothelial cells exposed to smokers' serum decreased nitric oxide (NO) production and endothelial nitric oxide synthase (eNOS) activity in the presence of increased eNOS expression. In the present study, we examined whether these observations extended to human coronary artery endothelial… (More)
The predictors of troponin release after percutaneous coronary intervention were prospectively assessed in 405 consecutive patients. Troponin release occurred frequently (27%) and was associated with complications during the procedure, including sapheneous vein graft interventions, multistent use, glycoprotein IIb/IIIa use, and a history of… (More)
Fifty-one patients with human immunodeficiency virus infection and acute coronary syndromes were identified. Nearly all patients (98%) had traditional coronary risk factors. Revascularization procedures were performed safely with low in-hospital mortality.
BACKGROUND Health care workers (HCWs) play a critical role in prevention of health care-associated infections such as methicillin-resistant Staphylococcus aureus (MRSA), but glove and gown contact precautions and hand hygiene may not be consistently used with vulnerable patients. METHODS A cross-sectional survey of MRSA knowledge, attitudes/perceptions,… (More)
OBJECTIVES To determine the impact of moderate alcohol consumption on long term prognosis after successful coronary stenting, and whether it could be related to preprocedural plasma C reactive protein (CRP). DESIGN Part of the prospectively designed GENERATION study which investigated the impact of several biochemical factors, including plasma CRP, on… (More)
Increased creatine kinase-MB isoenzymes after coronary stenting are common, and many studies have suggested an association of this increase with an adverse long-term prognosis. How such postprocedural creatine kinase-MB release affects long-term prognosis remains unclear. Whether any actual causal relation exists remains unanswered.
BACKGROUND The present study was undertaken to investigate the effect of statins plus omega-3 polyunsaturated fatty acids (PUFAs) on endothelial function and lipid profile in South Asians with dyslipidemia and endothelial dysfunction, a population at high risk for premature coronary artery disease. METHODS Thirty subjects were randomized to rosuvastatin… (More)
