Why the cTnI/cTnT Ratio May Matter: A New Signal for Distinguishing Acute Necrotic From Chronic Myocardial Injury

By MedXY 05/12/2026

A large multicohort and experimental study suggests the cTnI/cTnT ratio is biologically informative, separates acute from chronic myocardial injury, and modestly improves type 1 versus type 2 MI discrimination.

Troponin Assay Transitions: Increased Clinical Burden Without Improved Cardiovascular Outcomes

By MedXY 12/24/2025

Switching from high-sensitivity troponin I to T significantly increases diagnoses of myocardial injury and hospital admissions without improving long-term cardiovascular outcomes, while low-threshold troponin I remains a safe tool for rapid rule-out.

High-Sensitivity Cardiac Troponins and Dementia Risk: Insights from Longitudinal Cohort Studies

By MedXY 11/28/2025

Elevated high-sensitivity cardiac troponin I and T levels, indicative of subclinical myocardial injury in midlife, are associated with accelerated cognitive decline, structural brain changes, and increased dementia risk in later life.
