Randomized Controlled Trial Multicenter Study Comparative StudySafety and efficacy of high- versus low-dose aspirin after primary percutaneous coronary intervention in ST-segment elevation myocardial infarction: the HORIZONS-AMI (Harmonizing Outcomes With Revascularization and Stents in Acute Myocardial Infarction) trial.
This study sought to examine the relationship between the aspirin dose prescribed at hospital discharge and long-term outcomes after ST-segment elevation myocardial infarction in patients treated with primary percutaneous coronary intervention (PCI). ⋯ In patients with ST-segment elevation myocardial infarction undergoing primary PCI, discharge on high-dose rather than low-dose aspirin may increase the rate of major bleeding without providing additional ischemic benefit.

Improved survival associated with pre-hospital triage strategy in a large regional ST-segment elevation myocardial infarction program.
This study sought to compare the 1-year survival of patients diagnosed with ST-segment elevation myocardial infarction (STEMI) and transferred via pre-hospital triage strategy for primary percutaneous coronary intervention (PCI) with those transferred via inter-hospital transfer within a large suburban region in Canada. ⋯ Pre-hospital triage strategy was associated with improved survival rate in patients undergoing primary PCI in a regional STEMI program.

Incidence, management, and outcomes of cardiac tamponade during transcatheter aortic valve implantation: a single-center study.
The aim of this study was to explore the incidence, causes, and outcomes of cardiac tamponade in patients undergoing transcatheter aortic valve implantation (TAVI). ⋯ Cardiac tamponade during TAVI is not frequent but is associated with high mortality rates especially when left-sided structures are involved. Meticulous handling of the equipment and improvements in the safety of currently used devices could further reduce the occurrence of this complication.

Comparative StudyWalking beyond the GRACE (Global Registry of Acute Coronary Events) model in the death risk stratification during hospitalization in patients with acute coronary syndrome: what do the AR-G (ACTION [Acute Coronary Treatment and Intervention Outcomes Network] Registry and GWTG [Get With the Guidelines] Database), NCDR (National Cardiovascular Data Registry), and EuroHeart Risk Scores Provide?
This study sought to compare the in-hospital prognostic values of the original and updated GRACE (Global Registry of Acute Coronary Events) risk score (RS) and the AR-G (ACTION [Acute Coronary Treatment and Intervention Outcomes Network] Registry and the GWTG [Get With the Guidelines] Database) RS in acute coronary syndromes (ACS). To evaluate the utility of recalculating risk after percutaneous coronary intervention (PCI) with newer RS models (NCDR [National Cardiovascular Data Registry] and EHS [EuroHeart Score] RS). ⋯ Despite having been developed over 8 years ago, the GRACE RS still maintains its excellent performance for predicting in-hospital risk of death among ACS patients.
