The impact of implementing a high sensitivity assay for cardiac troponin I on long term outcomes in patients with suspected acute coronary syndrome

Researchers from the United Kingdom evaluated the use of a high-sensitivity assay to measure cardiac troponin I and its impact on myocardial infarction (MI) risk or other long-term outcomes such as death at five years in individuals with suspected acute coronary syndrome.

Lasting heart concerns in kids post-MIS-C: Study urges ongoing cardiac checks

Researchers evaluated the long-term cardiovascular effects in children after treatment for MIS-C, a condition linked to COVID-19. They found that regardless of initial heart injury, most children displayed persistent cardiac abnormalities, underscoring the importance of ongoing cardiac monitoring post-recovery.

High troponin levels associated with increased risk of death from any cause

A high level of troponin-;a protein normally used to exclude the possibility of a heart attack in patients with chest pain-;may signal a heightened risk of death from any cause within the next couple of years, even in the absence of known or suspected cardiovascular disease, suggests research published online in the journal Heart.

Improved diagnosis of occlusion myocardial infarction using novel machine learning tools

Machine learning models were developed to diagnose heart attacks in patients with no ST-elevation on their initial electrocardiogram, outperforming clinicians and improving accuracy. The models' risk score enhanced diagnostic accuracy and reclassified chest pain patients, providing mechanistic links to heart injury.

One-third of adults in the U.S. with Type 2 diabetes may have symptomless cardiovascular disease

1 in 3 adults with Type 2 diabetes may have undetected cardiovascular disease. Elevated levels of two protein biomarkers that indicate heart damage were associated with undetected or symptomless cardiovascular disease in adults with Type 2 diabetes compared to those without Type 2 diabetes, according to new research published today in the Journal of the American Heart Association, an open access, peer-reviewed journal of the American Heart Association.

Mice study reveals a way to turn back the clock after heart attack

A recent study using mice has revealed a way to turn back the clock after heart attack. The researchers behind the work used RNAs to instruct cells in an injured heart to eliminate scar tissue and recreate cardiac muscle, allowing the heart to function like new again.
