Myocardial Contusion: Sensitivity and Specificity
Introduction: Myocardial contusions are injuries to the heart muscle from blunt trauma to the chest. Principal complications are arrhythmias and ventricular (especially RV) dysfunction.
In a large case series (PMID: 2363607), blunt trauma patients who survived to admission and were suspected of having myocardial contusion were unlikely to have arrythmias (only 4 of 95 patients developed arrhythmias necessitating treatment), and none developed new heart failure. No patients admitted to unmonitored beds had arrhythmia or new heart failure. In this series, cardiac enzymes were frequently elevated but did not predict morbidity.
