Post-PCI Troponin Kinetics Reveal Hemorrhagic Transformation as a Critical Driver of In-Hospital Mortality in STEMI

By MedXY 12/31/2025

A multicenter study identifies high-sensitivity troponin I kinetics as a diagnostic marker for hemorrhagic myocardial infarction, linking this reperfusion injury to a nearly threefold increase in the risk of in-hospital mortality following primary percutaneous coronary intervention.

High-Sensitivity Troponin I: A Poor Predictor of Anthracycline-Induced Left Ventricular Dysfunction?

By MedXY 12/25/2025

The Cardiac CARE trial reveals that high-sensitivity cardiac troponin I levels do not correlate with cumulative anthracycline dose and only weakly predict subsequent declines in left ventricular function, challenging existing risk-stratification models in cardio-oncology.
