Myocardial infarction complications may occur immediately following a myocardial infarction (heart attack) (in the acute phase), or may need time to develop (a chronic problem). After an infarction, an obvious complication is a second infarction, which may occur in the domain of another atherosclerotic coronary artery, or in the same zone if ...
Angina, also known as angina pectoris, is chest pain or pressure, usually caused by insufficient blood flow to the heart muscle (myocardium). [2] It is most commonly a symptom of coronary artery disease. [2] Angina is typically the result of partial obstruction or spasm of the arteries that supply blood to the heart muscle. [3]
Coronary artery ectasia is characterized by an increased wall stress of the vessel, thinning of the arterial wall which causes progressive dilation and remodelling of the vessel. [2] The permanent dilation of the artery is thought to be mainly caused by inflammation, triggered by disease, chemicals, or physical stress of the vessel. [3]
[26] [27] Angina can also occur due to spasm of the coronary arteries, even in individuals without atherosclerosis. [28] In coronary artery spasm, the vessel constricts to limit blood flow through the artery, causing a decrease in oxygen supply to the heart, although the mechanisms for this phenomenon are not fully understood.
Angina comes from the latin angere, which means to strangle, and pectoris comes from pectus, meaning chest—so angina pectoris loosely translates to “strangling of the chest”, which actually makes a lot of sense, because angina pectoris is caused by reduced blood flow which causes ischemia to the heart muscle, or lack of oxygen to the ...
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.
“Heavy drinking raises blood pressure, increases triglycerides, promotes inflammation and can cause arrhythmias, all of which elevate the risk of heart disease and stroke,” says Routhenstein.
Chronic inflammation Various markers of low-grade chronic inflammation have been found in cases of coronary vasospasm. [14] [15] In addition to this, one of the risk factors for coronary vasospasm is smoking. [9] [10] Chronic inflammation due to smoking has been shown to be damaging to endothelial cell function.
