Abstract
Heart blast injury is divided into primary and secondary ones. Primary heart blast injury refers to injury caused by overpressure; secondary heart blast injury refers to heart trauma caused by dynamic pressure such as throwing, impact, etc., including the injury to pericardium, myocardium (papillary muscle), valves, and endocardium directly caused by the high pressure of the lung–heart tissue interface (air-/non-air-filled tissue), and coronary air embolism caused by alveolar pulmonary venous fistula; meanwhile, cardiac tamponade and reflex vagus nerve stimulation induced by active hemorrhage in the pericardial cavity, and hypoxemia and malignant arrhythmia resulting from combined lung injury, could further aggravate myocardial injury, worsen the circulatory system, and even lead to death. In addition, the combined blast injury of heart and other parts (such as pulmonary contusion, head and abdomen injury, pelvic or long bone fracture, etc.) is always fatal with a high incidence.
