Yes, a clot in the coronary artery can cause a myocardial infarction or a heart attack. Most heart attacks are caused by blood clots that come loose from the walls of the arteries.
Its due to increase surge of catecholeamines cause by sympethetic nervous system....
referred pain
Np. Angina refers to chest pain, such as from vasospasm of the coronary arteries, or from an impending myocardial infarction. The term, myocadial infarction, refers to cardiac muscle damage and death (a small MI involving a small area of the heart, and a large MI involving a larger portion of the heart).
A heart attack or myocardial infarction (MI) can cause damage by brain damage, can lead to stokes, and also have the risk of having a seconf MI.
In approxiemetly 25% of patients that have had a MI, a ventricular arrthymia or fibrilliation will occur and lead to fatality and is the leading cause of death post MI.
The blood vessel gets blocked. In the heart, if one of the coronary arteries get blocked by smoking, it can cause a myocardial infarction (Heart Attack).
1) Ischeamic cardiac diseases. 2) thrombosis of veins, which can get dislodged in pulmonary circulation and cause pulmonary embolism. 3) myocardial infarction
The most common cause is sudden cardiac arrhythmia, followed by MI (myocardial infarction or heart attack).
For a few seconds, not likely. However, if hypothermia begins to set in, the conditions for a myocardial infarction (heart attack) increase significantly.
Myocardial Infarction (MI) is a heart attack, also called a coronary event. Most common cause of MI is blocked blood vessels in the heart.
A myocardial infarction is a heart attack. It is caused when the cells of the muscle of the heart do not get enough oxygen and glucose, resulting in anaerobic metabolism and buildup of products of that metabolism, resulting in cellular acidosis, shutdown of cellular metabolism, and finally cell death and necrosis. In the overwhelming number of casea, this process results from the blockage of a coronary artery by a thrombus formed when a cholesterol plaque ruptures, causing a clot to form. It can be caused by several other things, however. Severe dehydration, severe hypotension, partial blockage of an artery by a large plaque that has not ruptured and other low flow states can result in not enough oxygen and glucose getting to the cells. Also, anything that increases the metabolic demands on the heart muscle can cause similar effects - sepsis with shock, toxins, drugs, and poisonings.
