Comparative StudyIschemic and bleeding outcomes in women treated with bivalirudin during percutaneous coronary intervention: a subgroup analysis of the Randomized Evaluation in PCI Linking Angiomax to Reduced Clinical Events (REPLACE)-2 trial.
Outcomes in women undergoing percutaneous coronary intervention (PCI) in the contemporary era are poorly defined. The REPLACE-2 trial demonstrated that bivalirudin with provisional glycoprotein IIb/IIIa (GpIIb-IIIa) blockade is noninferior to heparin with planned GpIIb-IIIa blockade during PCI, with regard to ischemic and bleeding end points. ⋯ Women remain at higher risk for poorer outcomes with contemporary PCI, likely because of comorbidities. Bivalirudin with provisional GpIIb-IIIa confers similar protection against ischemic end points compared with heparin and planned GpIIb-IIIa blockade and significantly reduces the inherent bleeding risk of women undergoing contemporary PCI.

Comparative StudyLow prevalence of B-type natriuretic peptide levels < 100 pg/mL in patients with heart failure at hospital discharge.
In patients with acute heart failure (HF) presenting at the emergency department, a B-type natriuretic peptide (BNP) level < 100 pg/mL was found in only 10% of the patients. However, in a more stable outpatient HF population from another study, a BNP level < 100 pg/mL was found in as many as 21% of the patients. Therefore, we aimed to investigate the prevalence and characteristics of stabilized patients with BNP levels < 100 pg/mL before discharge after admission for decompensated heart failure HF. ⋯ In clinically stable patients with a recent admission for decompensated HF, only 10% had BNP levels > or = 100 pg/mL. These patients with low BNP levels seemed to have less severe HF and more frequently had preserved systolic function compared with patients with BNP levels > or = 100 pg/mL.

How obesity affects the cut-points for B-type natriuretic peptide in the diagnosis of acute heart failure. Results from the Breathing Not Properly Multinational Study.
B-type natriuretic peptide (BNP) is valuable in diagnosing heart failure (HF), but its utility in obese patients is unknown. Studies have suggested a cut-point of BNP > or = 100 pg/mL for the diagnosis of HF; however, there is an inverse relation between BNP levels and body mass index. We evaluated differential cut-points for BNP in diagnosing acute HF across body mass index levels to determine whether alternative cut-points can improve diagnosis. ⋯ Body mass index influences the selection of cut-points for BNP in diagnosing acute HF. A lower cut-point (BNP > or = 54 pg/mL) should be used in severely obese patients to preserve sensitivity. A higher cut-point in lean patients (BNP > or = 170 pg/mL) could be used to increase specificity.

Elevated plasma N-terminal pro-brain natriuretic peptide levels in acute ischemic stroke.
B-type natriuretic peptide (BNP) is a neurohormone secreted mainly in the cardiac ventricles in response to volume expansion and pressure overload. The aim of this study was to assess plasma N-terminal proBNP (NT-proBNP) changes in acute ischemic stroke (AIS). ⋯ Our results show that NT-proBNP plasma levels are significantly elevated in AIS and might be of clinical importance as a supplementary tool for the assessment of cardiovascular function in patients with AIS.

Randomized Controlled TrialA randomized, placebo-controlled, double-blind, crossover study to evaluate the efficacy of oral sildenafil therapy in severe pulmonary artery hypertension.
Severe pulmonary artery hypertension (PAH) is a disorder with limited treatment options. Recently, several newer drugs have recently been introduced to treat PAH. Sildenafil is one which has shown promise in several uncontrolled studies, but controlled trials have been few. In this randomized placebo-controlled study, we evaluated the efficacy of oral sildenafil in idiopathic PAH and PAH caused by Eisenmenger syndrome. ⋯ Sildenafil significantly improved the symptomatic status, exercise capacity, NYHA class, and hemodynamic parameters of patients with severe PAH and can be safely used as a primary or adjunctive treatment of the same.
