A heart attack is a potentially life-threatening medical emergency that can lead to cardiac arrest or death. Heart attacks are common, too, with an estimated 805,000 people in the United States ...
Coronary thrombosis is defined as the formation of a blood clot inside a blood vessel of the heart. This blood clot may then restrict blood flow within the heart, leading to heart tissue damage, or a myocardial infarction, also known as a heart attack.
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 ...
Plaques in the walls of the coronary arteries can rupture, resulting in occlusion of the artery and deprivation of blood flow and oxygen to the heart muscle, resulting in cardiac cell death. [9] This is known as myocardial infarction. [9] A heart attack can cause arrhythmias, as well as permanent damage to the heart muscle. [25]
Myocardial infarction; Other names: Acute myocardial infarction (AMI), heart attack: A myocardial infarction occurs when an atherosclerotic plaque slowly builds up in the inner lining of a coronary artery and then suddenly ruptures, causing catastrophic thrombus formation, totally occluding the artery and preventing blood flow downstream to the heart muscle.
While heart disease and stroke deaths had been decreasing in both rural and urban communities before 2019, they shot up with the arrival of the pandemic in 2020, reversing decades of progress.
The most common cause of myocardial rupture is a recent myocardial infarction, with the rupture typically occurring three to five days after infarction. [3] Other causes of rupture include cardiac trauma, endocarditis (infection of the heart), [4] [5] cardiac tumors, infiltrative diseases of the heart, [4] and aortic dissection. [citation needed]
After a follow-up of a median of eight years, about 5% of study participants developed atrial fibrillation, about 2.1% developed heart failure, almost 2% had a heart attack, and a little less than ...
