EUROPEAN HEART JOURNAL. Biodegradable polymer drug-eluting stents reduce the risk of stent thrombosis at 4 years in patients undergoing percutaneous coronary intervention

Giulio G. Stefanini, Robert A. Byrne, Patrick W. Serruys, Antoinette de Waha, Bernhard Meier, Steffen Massberg, Peter Jüni, Albert Schömig, Stephan Windecker and Adnan Kastrati

Aims: The efficacy of durable polymer drug-eluting stents (DES) is delivered at the expense of delayed healing of the stented vessel. Biodegradable polymer DES aim to avoid this shortcoming and may potentially improve long-term clinical outcomes, with benefit expected to accrue over time. We sought to compare long-term outcomes in patients treated with biodegradable polymer DES vs. durable polymer sirolimus-eluting stents (SES).

REVISTA ESPAÑOLA DE CARDIOLOGIA. Insuficiencia cardiaca aguda post-alta hospitalaria tras un síndrome coronario agudo sin elevación del segmento-ST y riesgo de muerte e infarto agudo de miocardio subsiguiente

Julio Núñez, Juan Sanchis, Eduardo Núñez, Vicent Bodí, Luis Mainar, Gema Miñana, Pilar Merlos, Patricia Palau, Oliver Husser, Eva Rumiz, Francisco J. Chorro y Àngel Llàcer

Introducción y objetivos. La información disponible acerca del impacto pronóstico de un episodio de rehospitalización por insuficiencia cardiaca aguda (ICA) tras un síndrome coronario agudo sin elevación del segmento ST (SCASEST) es escasa. El objetivo de este trabajo fue evaluar el valor pronóstico atribuible a un primer ingreso por ICA en cuanto a riesgo de infarto agudo de miocardio (IAM) y mortalidad en pacientes supervivientes a un episodio de SCASEST de alto riesgo.

CLINICAL CARDIOLOGY. Differential Prognostic Effect of Revascularization According to a Simple Comorbidity Index in High-Risk Non–ST-Segment Elevation Acute Coronary Syndrome

Patricia Palau, MD; Julio Núñez, MD; Juan Sanchis, MD, FESC; Oliver Husser, MD; Vicente Bod´ı, MD, FACC, FESC; Eduardo N´u˜nez, MD, MPH; Gema Mi˜nana, MD; Line Boesen, MD; Silvia Ventura, MD; Angel Ll`acer, MD, FESC

Background: Data on the effect of revascularization on outcome in patients with high-risk non–ST-segment elevation acute coronary syndrome (NSTEACS) and significant comorbidities are scarce. Recently, a simple comorbidity index (SCI) including 5 comorbidities (renal failure, dementia, peripheral artery disease, heart failure, and prior myocardial infarction [MI]) has shown to be a useful tool for risk stratification. Nevertheless, therapeutic implications have not been derived.
