Featured Articles
Article 1: Great debate: the universal definition of myocardial infarction is flawed and should be put to rest.
Journal: European heart journal
PubMed Link: https://pubmed.ncbi.nlm.nih.gov/40923895
Summary: The universal definition of myocardial infarction relies on clinical evidence of myocardial ischemia and biomarker evidence of myocardial cell death, primarily cardiac troponins. The authors argue the current universal definition of myocardial infarction is flawed.
Article 2: Cytosolic calcium handling signature: integration with clinical predictors enhances prediction of post-operative atrial fibrillation.
Journal: European heart journal
PubMed Link: https://pubmed.ncbi.nlm.nih.gov/40923107
Summary: This study evaluated whether incorporating cytosolic calcium handling measurements with clinical risk factors improves post-operative atrial fibrillation risk prediction. Analyzing data from 558 patients undergoing cardiac surgery, including atrial cardiomyocytes from a subset, integrating calcium handling abnormalities with clinical factors enhanced atrial fibrillation risk prediction after cardiac surgery.
Transcript
Today’s date is September 10, 2025. Welcome to Cardiology Today. Here are the latest research findings.
Article number one. Great debate: the universal definition of myocardial infarction is flawed and should be put to rest. The universal definition of myocardial infarction relies on clinical evidence of myocardial ischemia and biomarker evidence of myocardial cell death, primarily cardiac troponins. The authors argue the current universal definition of myocardial infarction is flawed.
Article number two. Cytosolic calcium handling signature: integration with clinical predictors enhances prediction of post-operative atrial fibrillation. This study evaluated whether incorporating cytosolic calcium handling measurements with clinical risk factors improves post-operative atrial fibrillation risk prediction. Analyzing data from 558 patients undergoing cardiac surgery, including atrial cardiomyocytes from a subset, integrating calcium handling abnormalities with clinical factors enhanced atrial fibrillation risk prediction after cardiac surgery.
