Hospital Variation in the Utilization of Short-Term Nondurable Mechanical Circulatory Support in Myocardial Infarction Complicated by Cardiogenic Shock.
Limited knowledge exists on inter-hospital variation in the utilization of short-term, nondurable mechanical circulatory support (MCS) for myocardial infarction (MI) complicated by cardiogenic shock (CS). ⋯ Wide variation exists in hospital use of MCS for MI with CS, unexplained by patient characteristics. The predominant form of MCS use is intra-aortic balloon pump. Risk-adjusted mortality rates were not different between higher and lower MCS-utilizing hospitals.

Incidence, Mortality, and Outcome-Predictors of Sudden Cardiac Arrest Complicating Myocardial Infarction Prior to Hospital Admission.
Mortality of ST-segment-elevation myocardial infarction (STEMI) decreased drastically, mainly through reduction in inhospital mortality. Prehospital sudden cardiac arrest (SCA) became one of the most feared complications. We assessed the incidence, outcome, and prognosis' predictors of prehospital SCA occurring after emergency medical services (EMS) arrival. ⋯ More than 1 of 20 STEMI presents prehospital SCA after EMS arrival. SCA occurrence is associated with a 10-fold higher mortality at hospital discharge compared with STEMI without SCA. PCI is the strongest survival predictor, leading to a twice-lower mortality. This highlights the persistently dramatic impact of SCA on STEMI and the major importance of PCI in this setting.

Prognostic Relevance of Left Ventricular Myocardial Performance After Transcatheter Aortic Valve Replacement.
The left-ventricular myocardial performance index Tei is an echocardiographic parameter that incorporates the information of systolic and diastolic time intervals. While the prognostic value of selected systolic and diastolic parameters is well established after transcatheter aortic valve replacement, the role of Tei has not been evaluated in this setting. ⋯ URL: https://www.clinicaltrials.gov .

Association of Anemia With Outcomes Among ST-Segment-Elevation Myocardial Infarction Patients Receiving Primary Percutaneous Coronary Intervention.
Anemia may confer a poor prognosis among patients with the acute coronary syndrome. However, few data exist on the association of anemia with in-hospital outcomes, including bleeding, among ST-segment-elevation myocardial infarction patients receiving primary percutaneous coronary intervention. ⋯ In a contemporary ST-segment-elevation myocardial infarction cohort receiving primary percutaneous coronary intervention, nearly 1 in 5 patients were anemic. Anemia was associated with increased comorbidities and higher-risk features on presentation and was independently associated with subsequent major in-hospital bleeding but not all-cause mortality. These results suggest that anemic ST-segment-elevation myocardial infarction patients may safely receive timely primary percutaneous coronary intervention but with particular consideration for bleeding avoidance strategies.
