Courtesy of Dr. Santiago F. Coroleu. Dual antiplatelet therapy (DAPT) with aspirin and clopidogrel after percutaneous coronary intervention (PCI) reduces the risk for coronary thrombotic events (CTEs) at the expense of increasing risk for major bleeding (MB). However, the lack of information to accurately predict the occurrence of each event in out-of-hospital patients under...
Courtesy of Dr. Brian Nazareth Donato. The relative safety of drug-eluting stents (DES) and conventional bare-metal stents (BMS) in primary angioplasty (percutaneous coronary intervention, PCI) in patients with ST elevation myocardial infarction (STEMI) is still subject of debate. A search was carried out using Medline, CENTRAL, EMBASE, TCTMD and Cardiosource. There were 9673 patients included,...

Original Title: Tissue Protrusion after Stent Implantation. An ADAPT-DES Intravascular Ultrasound Substudy. Reference: Fuyu Qiu et al. J Am Coll Cardiol Intv. 2016;9(14):1499-1507. After DES implantation we may observe tissue protrusion (plaque or thrombus) relatively often, especially in unstable lesions; however, its clinical impact has not been studied. The aim of this study was...
Rio de Janeiro – June 8, 2016. SOLACI-SBHCI 2016, the largest meeting on Interventional Cardiology in Latin America started with more than 1500 attendees. After the opening, by Congress President Marcelo Josén de Carvalho Cantarelli, we honored Dr. José Eduardo Sousa, the first to perform a coronary catheterization in Brazil, 50 years ago. After...
Original Title: Pharmacodynamic Effects of Switching from Prasugrel to Ticagrelor Results of the Prospective, Randomized SWAP-3 Study Reference: J Am Coll Cardiol Intv. 2016;() Epub ahead of print. Courtesy of Dr. Agustín Vecchia. At present, the pharmacodynamic effects of switching from prasugrel to ticagrelor in patients under dual APT remain unknown. The present prospective, randomized,...
Original Title: Revascularization in Patients with Multivessel Coronary Artery Disease and Severe Left Ventricular Systolic Dysfunction: Everolimus Eluting Stents vs Coronary Artery Bypass Graft Surgery Reference: Bangalore et al. Circulation. 2016 May 5. Epub ahead of print. Courtesy of Dr. Guillermo Migliaro. Guidelines recommend coronary artery bypass graft surgery (CABG) over percutaneous coronary...
The use of morphine in patients undergoing ST elevation acute coronary syndromes is associated to higher platelet reactivity and lower thrombolysiscapacity, according to this small study. The negative effects seem to resolve 2 days after administration. This transient effect is believed to be the result of the inhibition of the normal muscular activity of the...
