Discontinuation of β-blockers in stable patients with previous myocardial infarction, preserved left ventricular ejection fraction, and no heart failure: a pooled analysis of individual patient data.

BACKGROUND Many stable patients with chronic coronary syndrome continue β-blocker therapy for years after a myocardial infarction, despite having no clear ongoing indication. Whether β-blockers can be safely discontinued in such patients remains uncertain. The objective of this analysis was to assess the non-inferiorit...

Association of Shock-to-Balloon Time With Outcomes in Acute Myocardial Infarction With Cardiogenic Shock Requiring VA-ECMO.

The optimal timing of percutaneous coronary intervention (PCI) in patients with acute myocardial infarction complicated by cardiogenic shock (AMI-CS) who are supported with venoarterial extracorporeal membrane oxygenation (VA-ECMO) remains uncertain. We aimed to evaluate the prognostic impact of shock-to-balloon time (...

Incremental Value of Left Atrial Strain in HFA-PEFF for Heart Failure With Preserved Ejection Fraction.

BACKGROUND Because exercise testing is not feasible for a substantial subset of patients with suspected heart failure with preserved ejection fraction (HFpEF), the Heart Failure Association-Pre-test assessment, Echocardiography and natriuretic peptide score, Functional testing in cases of uncertainty, Final etiology (H...
