Comparison of Strut Coverage at 6 Months by Optical Coherence Tomography With Everolimus-Eluting Stenting of Bare-Metal Stent Restenosis Versus Stenosis of Nonstented Atherosclerotic Narrowing (from the DESERT Study)

Nov 30, 2016 by in CARDIOLOGY Comments Off on Comparison of Strut Coverage at 6 Months by Optical Coherence Tomography With Everolimus-Eluting Stenting of Bare-Metal Stent Restenosis Versus Stenosis of Nonstented Atherosclerotic Narrowing (from the DESERT Study)

Incomplete struts coverage is a predictor of late stent thrombosis after implantation of the drug-eluting stents (DES) in atherosclerotic lesions. The process of struts coverage in DES implanted for bare-metal…

Glycoprotein IIb/IIIa Receptor Inhibitors in Combination With Vorapaxar, a Platelet Thrombin Receptor Antagonist, Among Patients With Non–ST-Segment Elevation Acute Coronary Syndromes (from the TRACER Trial)

Nov 30, 2016 by in CARDIOLOGY Comments Off on Glycoprotein IIb/IIIa Receptor Inhibitors in Combination With Vorapaxar, a Platelet Thrombin Receptor Antagonist, Among Patients With Non–ST-Segment Elevation Acute Coronary Syndromes (from the TRACER Trial)

We evaluated the interaction between protease-activated receptor-1 antagonist vorapaxar and concomitant glycoprotein (GP) IIb/IIIa receptor inhibitors in patients with non–ST-segment elevation acute coronary syndromes who underwent PCI. In Thrombin Receptor…

Usefulness of N-terminal Pro–brain Natriuretic Peptide and Myocardial Perfusion in Asymptomatic Adults (from the Multi-Ethnic Study of Atherosclerosis)

Nov 30, 2016 by in CARDIOLOGY Comments Off on Usefulness of N-terminal Pro–brain Natriuretic Peptide and Myocardial Perfusion in Asymptomatic Adults (from the Multi-Ethnic Study of Atherosclerosis)

This study sought to investigate the relation between myocardial perfusion and N-terminal pro-brain natriuretic peptide (NT-proBNP) in asymptomatic adults without overt coronary artery disease. NT-proBNP is a cardiac neurohormone secreted…

Evidence That High Catecholamine Levels Produced by Pheochromocytoma May be Responsible for Tako-Tsubo Cardiomyopathy

Nov 30, 2016 by in CARDIOLOGY Comments Off on Evidence That High Catecholamine Levels Produced by Pheochromocytoma May be Responsible for Tako-Tsubo Cardiomyopathy

Tako-tsubo cardiomyopathy (TC) is a novel form of acute heart failure, characterized by regional left ventricular dysfunction without coronary artery obstruction, and usually triggered by a stressful event. Excessive circulating…
