N-terminal B-type natriuretic peptide assessment provides incremental prognostic information in patients with acute coronary syndromes and normal troponin T values upon admission.
The purpose of this study was to determine the prognostic value of N-terminal B-type natriuretic peptide (NT-proBNP) in two independent samples of patients presenting with acute coronary syndromes (ACS) and normal troponin T (TnT) values. ⋯ Among patients with suspected ACS considered to be at low risk because of normal troponin values, NT-proBNP above 474 pg/ml is able to discriminate individuals at higher risk. Because of its incremental prognostic value, NT-proBNP assessment should be considered in clinical routine for risk stratification of patients with normal troponin.

Randomized Controlled Trial Multicenter Study Comparative StudyDrug-eluting stenting followed by cilostazol treatment reduces late restenosis in patients with diabetes mellitus the DECLARE-DIABETES Trial (A Randomized Comparison of Triple Antiplatelet Therapy with Dual Antiplatelet Therapy After Drug-Eluting Stent Implantation in Diabetic Patients).
We sought to evaluate the impact of cilostazol on neointimal hyperplasia after drug-eluting stent (DES) implantation in patients with diabetes mellitus (DM). ⋯ Triple antiplatelet therapy after DES implantation decreased angiographic restenosis and extent of late loss, resulting in a reduced risk of 9-month TLR compared with dual antiplatelet therapy in diabetic patients.

Atrial fibrillation in patients with Brugada syndrome relationships of gene mutation, electrophysiology, and clinical backgrounds.
The goal of our work was to examine the relationships of atrial fibrillation (AF) with genetic, clinical, and electrophysiological backgrounds in Brugada syndrome (BrS). ⋯ Spontaneous AF and VF are closely linked clinically and electrophysiologically in BrS patients. Patients with spontaneous AF have more severe clinical backgrounds in BrS. SCN5A mutation is associated with electrical abnormality but not disease severity.

Randomized Controlled Trial Comparative StudyDirect stenting for stable angina pectoris is associated with reduced periprocedural microcirculatory injury compared with stenting after pre-dilation.
We conducted a randomized study to compare the effect of direct stenting (DS) and conventional stenting (CS) on post-procedural index of microcirculatory resistance (IMR) values. ⋯ In patients undergoing successful coronary stenting for stable angina, DS is associated with reduced microvascular dysfunction induced by PCI as compared with CS.

Randomized Controlled Trial Multicenter StudyRandomized controlled trial of an implantable continuous hemodynamic monitor in patients with advanced heart failure: the COMPASS-HF study.
The purpose of this study was to determine whether a heart failure (HF) management strategy using continuous intracardiac pressure monitoring could decrease HF morbidity. ⋯ The implantable continuous hemodynamic monitor-guided care did not significantly reduce total HF-related events compared with optimal medical management. Additional trials will be necessary to establish the clinical benefit of implantable continuous hemodynamic monitor-guided care in patients with advanced HF.
