Terminology. Myocardial infarction (MI) refers to tissue death ( infarction) of the heart muscle ( myocardium) caused by ischemia, the lack of oxygen delivery to myocardial tissue. It is a type of acute coronary syndrome, which describes a sudden or short-term change in symptoms related to blood flow to the heart. [22]
Cardiac arrest. Cardiac arrest, also known as sudden cardiac arrest, is when the heart suddenly and unexpectedly stops beating. [11] [1] As a result, blood cannot properly circulate around the body and there is diminished blood flow to the brain and other organs. When the brain does not receive enough blood, this can cause a person to lose ...
Coronary thrombosis is most commonly caused as a downstream effect of atherosclerosis, a buildup of cholesterol and fats in the artery walls. The smaller vessel diameter allows less blood to flow and facilitates progression to a myocardial infarction. Leading risk factors for coronary thrombosis are high low-density lipoprotein cholesterol ...
Cardiogenic shock is caused by the failure of the heart to pump effectively. It is due to damage to the heart muscle, most often from a heart attack or myocardial contusion.[6] Other causes include abnormal heart rhythms, cardiomyopathy, heart valveproblems, ventricular outflow obstruction (i.e. systolic anterior motion in hypertrophic ...
Diabetic ketoacidosis ( DKA) is a potentially life-threatening complication of diabetes mellitus. [1] Signs and symptoms may include vomiting, abdominal pain, deep gasping breathing, increased urination, weakness, confusion and occasionally loss of consciousness. [1] A person's breath may develop a specific "fruity" smell. [1]
Cardiopulmonary resuscitation (CPR) is an emergency procedure consisting of chest compressions often combined with artificial ventilation, or mouth to mouth in an effort to manually preserve intact brain function until further measures are taken to restore spontaneous blood circulation and breathing in a person who is in cardiac arrest.
The mechanism in acute drowning is hypoxemia and irreversible cerebral anoxia due to submersion in liquid. [citation needed] Drowning would be considered a possible cause of death if the body was recovered from a body of water, near a fluid that could plausibly have caused drowning, or found with the head immersed in a fluid.
New research finds that a bout of anger impairs blood vessel function which can raise the risk of atherosclerosis, which in turn raises heart disease risk. New research shows how a surge of anger ...
