Abstract. Objectives. We sought to determine which transthoracic echocardiographic (TTE) measurements most strongly predict heart failure (HF) and to develop an index for risk stratification in outpatients with coronary artery disease (CAD). Background. Many TTE measurements have been shown to be predictive of HF, and they might be useful if ...

Prolonged electrocardiogram (ECG) QRS duration (>or=120 ms) is a risk factor for death in systolic heart failure, but its effects in heart failure with preserved systolic function (HFPSF) have not been extensively studied. We hypothesized that prolonged ECG QRS duration would independently predict long-term mortality in hospitalized HFPSF patients. We ...

The aim of this study was to examine the interaction between cigarette smoking and the clinical efficacy of clopidogrel in ST-segment elevation myocardial infarction (STEMI). Cigarette smoking induces cytochrome P450 (CYP)1A2, which converts clopidogrel into its active metabolite, and prior studies suggest greater inhibition of platelet aggregation by clopidogrel in ...

The current study was designed to determine whether drug-eluting stents (DES) are superior to bare-metal stents (BMS) in patients with stable angina. Percutaneous coronary intervention has been shown to decrease symptoms of angina; its use for stable angina has not been shown to reduce myocardial infarction or mortality. We conducted ...

Some meta-analyses of randomized clinical trials suggested that rosiglitazone could be associated with increased risk for myocardial infarction (MI). Available meta-analyses, based on studies sponsored by GlaxoSmithKline (GSK), failed to include all trials performed with rosiglitazone. Aim of this analysis is the assessment of the cardiovascular risk with rosiglitazone, using ...

BACKGROUND: Nitric oxide (NO) is produced from L-arginine by NO synthase and is an important molecule with antiatherogenic properties. Asymmetric dimethylarginine (ADMA) acts as an endogenous inhibitor of endothelial NO synthase. As such, it has been associated with endothelial dysfunction and elevated circulating levels of ADMA have been found in ...

BACKGROUND: Hemodialysis patients are prone to ischemic events potentially aggravated by hypoxia. The key player in adaptation to hypoxia is hypoxia-inducible factor-1 alpha (HIF-1alpha). Therefore, we investigated the association of HIF-1alpha polymorphisms with ischemia/hypoxia-related events in hemodialysis patients. METHODS: Patients on maintenance hemodialysis were enrolled from 4 training hospitals in ...
