Reference: Fox y colaboradores. Short-term Outcomes of Acute Myocardial Infarction in Patients with Acute Kidney Injury: A Report from the National Cardiovascular Data Registry. Circulation 2012 (in press). The presence of chronic renal failure is common in patients referred for angioplasty. Its presence is associated with increased mortality and bleeding. However, the prevalence is unknown as…
Hyperglycemia on admission, an excess risk for infarction
Reference: Planer et al. International Journal of Cardiology 2012 (in press) Prognosis of patients enrolled in acute myocardial infarction with ST segment elevation (STEMI) has improved markedly, particularly as a result of reperfusion therapy. Despite these improvements, patients with diabetes mellitus (DM) are a high risk group in the short and long term compared with…

JACC Cardiovasc Interv 2011; 4: 1119-28.2011; 4: 1119-28. Patients treated with zotarolimus-eluting stents (ZES) suffer no excess late ischemic events if they take dual antiplatelet therapy for 6 months instead of 12 months or longer,…
Incomplete Revascularization Linked With Mortality in Multivessel Disease Patients
Reference: Wu C, Dyer AM, Kinas SB, et al. Impact of incomplete revascularization on long-term mortality after coronary stenting. Circ Cardiovasc Interv 2011; 4: 413-21. Complete revascularization was defined as a reduction of stenosis to less than 50% in all diseased (≥ 70% stenosis) lesions in major epicardial coronary vessels at the initial hospitalization or within…
Off-Pump CABG Reduces Postoperative Stroke vs. Standard Surgery

Epub ahead of print. Patients who undergo off-pump coronary artery bypass grafting (CABG) surgery experience nearly one-third fewer postoperative strokes than those who receive standard surgery using cardiopulmonary…

Ticagrelor vs. Clopidogrel in ST elevation MI: Pros and cons
Platelet Inhibition in the PLATO study: insights from the ECG substudy. En el Estudio PLATO quedó evidenciado que el Ticagrelor disminuyó la mortalidad a 12 meses en comparación con el Clopidogrel en el tratamiento de pacientes post-angioplastía por un síndrome coronario agudo o por un cuadro estable (4,5 vs. 5,9%; P<0.001). Estos resultados fueron del…
