A myocardial infarction ( MI ), commonly known as a heart attack, occurs when blood flow decreases or stops in one of the coronary arteries of the heart, causing infarction (tissue death) to the heart muscle. [1] The most common symptom is retrosternal chest pain or discomfort that classically radiates to the left shoulder, arm, or jaw. [1]
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 ...
Acute coronary syndrome ( ACS) is a syndrome (a set of signs and symptoms) due to decreased blood flow in the coronary arteries such that part of the heart muscle is unable to function properly or dies. [ 1] The most common symptom is centrally located pressure-like chest pain, often radiating to the left shoulder [ 2] or angle of the jaw, and ...

Heart disease is a leading killer around the world and the top cause of death in the United States. It killed an estimated 17.9 million people in 2019, representing 32% of all deaths globally ...
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 ...
Cardiac arrest patients may experience “new dimensions of reality” once they are revived by performing CPR up to an hour after their hearts stop, suggests a new study.. Recent research on the ...
Pulseless electrical activity. Pulseless electrical activity ( PEA) is a form of cardiac arrest in which the electrocardiogram shows a heart rhythm that should produce a pulse, but does not. Pulseless electrical activity is found initially in about 20% of out-of-hospital cardiac arrests [1] and about 50% of in-hospital cardiac arrests. [2]
