The advent of cardiopulmonary resuscitation (CPR) revolutionized the care of patients with cardiac arrest, now allowing survival of up to 30% after out-of-hospital arrest due to arrhythmia; however, outcomes for cardiac arrest after trauma remain dismal, with less than 10% survival despite the most aggressive modern resuscitation techniques. The short time interval between cardiac arrest and br...

Half of trauma deaths are attributable to hypovolemic circulatory collapse (HCC). We established a model of HCC in rats involving minor trauma plus severe hemorrhagic shock (HS). HCC in this model was accompanied by a 50% reduction in peak acceleration of aortic blood flow and cardiomyocyte apoptosis. HCC and apoptosis increased with increasing duration of hypotension. Apoptosis required resusc...

Cardiac injury after blunt trauma is common but underreported. Common cardiac trauma after the blunt chest injury (BCI) is cardiac contusion; it is very rare to have cardiac valve injury. The mitral valve injury during chest trauma occurs when extreme pressure is applied at early systole during the isovolumic contraction between the closure of the mitral valve and the opening of the aortic valv...

Cardiac lesions secondary to blunt chest trauma vary from insignificant arrhythmias to fatal cardiac rupture. Of these, a distinction remains difficult; face to ST-segment elevation on ECG with positive cardiac biomarkers, is it a myocardial contusion or a genuine myocardial infarction (MI) secondary to coronary lesions? We report the case of a patient admitted for multiple trauma. Initial asse...

The specificity of serum CPK-MB for acute myocardial infarction was examined by retrospective analysis of 401 consecutive patients admitted to Coronary Care Unit over a three and one-half year period with suspected infarction in whom the isoenzyme was subsequently detected. Four patients (1 per cent) who died during the hospital admission had no autopsy evidence of acute myocardial infarction....

Nonpenetrating trauma to the chest can result in cardiac damage that may be overlooked because of associated injuries and the lack of obvious thoracic injury. The clinical diagnosis of important cardiac damage in this setting is difficult. We evaluated noninvasive tests for detecting myocardial damage in 100 patients with severe, nonpenetrating chest trauma. The noninvasive tests included seria...

Background. Penetrating injuries to the chest and in particular to the heart that results in pericardial tamponade and cardiac arrest requires immediate resuscitative thoracotomy as the only lifesaving technique and should be performed without delay. Objective. To describe an external cardiac tamponade caused by massive tension hemothorax from penetrating injury of the left internal mammary art...

Cardiac trauma caused by Swann-Ganz catheter may very rarely cause cardiac perforation, tamponade and right ventricular pseudoaneurysm. In contrast to left ventricular equivalants, pseudoaneurysms of the RV have a weak tendency to rupture. Its impact on patient outcomes should be assesed very carefully depending on its size, filling rate/capacity. It is possible not to operate the patient and f...

Commotio cordis is a phenomenon in which a sudden blunt impact to the chest causes sudden death in the absence of cardiac damage. This condition was first described in the middle of the 18th century in the context of chest trauma among workers.1 Through most of the 20th century, it was only sporadically reported. In the last 2 or 3 decades, commotio cordis events have primarily occurred in spor...
