A blunt cardiac injury is an injury to the heart as the result of blunt trauma, typically to the anterior chest wall. It can result in a variety of specific injuries to the heart, the most common of which is a myocardial contusion , which is a term for a bruise (contusion) to the heart after an injury. [ 1 ]
Bruits may be heard over the subclavian and axillary arteries [21] Intermediate magnification micrograph showing giant cell arteritis in a temporal artery biopsy.

The most common cause is coronary artery disease. Heart attacks are medical emergencies that require immediate medical attention, although some heart attacks can be “silent” and go undetected ...
Pain radiates most often to the left arm, but may also radiate to the lower jaw, neck, right arm, back, and upper abdomen. [28] [29] The pain most suggestive of an acute MI, with the highest likelihood ratio, is pain radiating to the right arm and shoulder. [30] [29] Similarly, chest pain similar to a previous heart attack is also suggestive. [31]
Severe chest pains are a clear sign of a heart attack, but even mild pain and pressure can be a serious warning sign. ... “Because of the type of nerve endings within the heart, blocked arteries ...
The cardinal symptom of critically decreased blood flow to the heart is chest pain, experienced as tightness, pressure, or burning. [9] Localization is most commonly around or over the chest and may radiate or be located to the arm, shoulder, neck, back, upper abdomen, or jaw. [9] This may be associated with sweating, nausea, or shortness of ...
A chest injury, also known as chest trauma, is any form of physical injury to the chest including the ribs, heart and lungs. Chest injuries account for 25% of all deaths from traumatic injury. [ 1 ] Typically chest injuries are caused by blunt mechanisms such as direct, indirect, compression, contusion, deceleration, or blasts [ 2 ] caused by ...
The right marginal arteries perfuse the right ventricle and the posterior descending artery perfuses the left ventricular posterior and inferior walls. There is also the conus artery, which is only present in about 45 percent of the human population, and which provides collateral blood flow to the heart when the left anterior descending artery ...
