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]
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 ...
Multi-infarct dementia results from a series of small strokes affecting several brain regions. Stroke-related dementia involving successive small strokes causes a more gradual decline in cognition. [4] Dementia may occur when neurodegenerative and cerebrovascular pathologies are mixed, as in susceptible elderly people (75 years and older).
Ischemic cardiomyopathy is a type of cardiomyopathy caused by a narrowing of the coronary arteries which supply blood to the heart. [4] Typically, patients with ischemic cardiomyopathy have a history of acute myocardial infarction, [5] however, it may occur in patients with coronary artery disease, but without a past history of acute myocardial infarction.
Data involving cardiac ischemia resulting from post acute COVID syndrome (or Long COVID) is evolving. Various studies have been combined to show a significant percentage of patients presenting with myocardial ischemia post COVID infection (infection requiring hospitalization) with no documented prior history of coronary disease.
The general appearance of patients may vary according to the experienced symptoms; the patient may be comfortable, or restless and in severe distress with an increased respiratory rate. A cool and pale skin is common and points to vasoconstriction. Some patients have low-grade fever (38–39 °C).
Symptoms of the acute coronary syndromes are similar. [8] The cardinal symptom of critically decreased blood flow to the heart is chest pain , experienced as tightness, pressure, or burning. [ 9 ] Localization is most commonly around or over the chest and may radiate or be located to the arm, shoulder, neck, back, upper abdomen, or jaw. [ 9 ]
The smaller the aneurysm the better the prognosis. There is less risk for ischemic myocardial damage and mortality with smaller aneurysms. Aneurysms with an internal diameter > 8 mm have poorer outcomes, since these aneurysms can be occluded and be associated with complications such as arrhythmias, myocardial infarction, or sudden death.
