Fu et al reported a score for predicting cardiac rupture after an acute myocardial infarction (AMI). The authors are from Chaoyang Hospital and Capital Medical University in Beijing.
Patient selection: acute myocardial infarction
Parameters:
(1) sex
(2) primary percutaneous coronary intervention (PCI)
(3) left ventricular ejection fraction (LVEF) in percent
(4) heart rate in beats per minute
(5) body mass index in kg per square meters
(6) age in years
