Presence of a thrombus in a coronary artery, often causing a myocardial infarction.
An obstruction, generally a blood clot, within a coronary artery which hinders the flow of blood to a part of the heart.
The formation of a blood clot on the rough inner surfaces of the atherosclerotic plaque.
A blood clot which blocks the coronary arteries, leading to a heart attack.
Presence of a blood clot in any of the arteries supplying the heart muscle, thereby obstructing the flow of blood to the heart.
Partial or complete blockage by a blood clot of one of the arteries that nourish the heart. Since the surface arteries (coronary arteries) provide the heart with oxygen-rich blood, the clot cuts off the oxygen supply to the heart muscle downstream. The result is myocardial infarction, or heart attack.
The formation of a blood clot (thrombus) in the coronary artery, which obstructs the flow of blood to the heart. This is usually due to ‘atheroma and results in the death (infarction) of part of the heart muscle. For symptoms and treatment see myocardial infarction.
A blood clot in a coronary artery, the most common cause of an acute coronary syndrome or a myocardial infarction (heart attack).
A condition known as coronary thrombosis occurs when a blood clot, called a thrombus, restricts or obstructs one of the coronary arteries, impeding the adequate supply of oxygen to a portion of the heart muscle. Typically, the thrombus develops within a blood vessel that has already been narrowed due to atherosclerosis. The abrupt blockage of a coronary artery leads to a myocardial infarction, commonly referred to as a heart attack.
A blood clot that hinders the flow of blood in the coronary artery can be very problematic. The coronary arteries are unique because they don’t have alternate connections with other arteries. This means that if one of these arteries becomes blocked, the specific section of the heart muscle it nourishes is left without an alternative blood supply. Consequently, when an artery is obstructed, the region it serves becomes oxygen-deprived, resulting in tissue death. Patients who experience coronary thrombosis must, therefore, undergo extended periods of bed rest following an attack. This allows the damaged muscle area to heal, form scar tissue, and replace the lost tissue.
