Background Reversible left ventricular dysfunction precipitated by emotional stress has been
reported, but the mechanism remains unknown. Methods We evaluated 19 patients who …

Background—The extent of microvascular obstruction during acute coronary occlusion may
determine the eventual magnitude of myocardial damage and thus, patient prognosis after …

Background— The extent of the peri-infarct zone by magnetic resonance imaging (MRI) has
been related to all-cause mortality in patients with coronary artery disease. This relationship …

Objectives : We examined whether the presence and extent of late gadolinium enhancement
(LGE) by cardiovascular magnetic resonance (CMR) predict adverse outcomes in …

To the Editor—Methods for analyzing single-cell data 1, 2, 3, 4 perform a core set of
computational tasks. These tasks include dimensionality reduction, cell clustering, cell-state …

Background— Contrast-enhanced (CE) MRI demonstrates a pattern of hypoenhancement
early after contrast injection in acute myocardial infarction (MI) and a pattern of …

Background— The ability to distinguish dysfunctional but viable myocardium from nonviable
tissue has important prognostic implications after myocardial infarction. The purpose of this …

Objectives. We aimed to validate contrast-enhanced echocardiography (CE) in the quantification
of microvascular obstruction (MO) against magnetic resonance imaging (MRI) and the …

Sudden cardiac death (SCD) from arrhythmias is a leading cause of mortality. For patients
at high SCD risk, prophylactic insertion of implantable cardioverter defibrillators (ICDs) …

Rationale: Although accumulating data support the efficacy of intramyocardial cell-based
therapy to improve left ventricular (LV) function in patients with chronic ischemic …
