Myocarditis refers to an underlying process that causes inflammation and injury of the heart. It does not refer to inflammation of the heart as a consequence of some other insult. Many secondary causes, such as a heart attack, can lead to inflammation of the myocardium and therefore the diagnosis of myocarditis cannot be made by evidence of ...
The word infarction means that some area of tissue has died due to a lack of blood flow, and therefore a lack of oxygen. “Myo” refers to the muscle, and “cardial” refers to the heart tissue. So with a heart attack, or MI, you have death of heart muscle cells because of a lack in blood flow, a process called necrosis.
Loffler syndrome, where eosinophils accumulate in the lung tissue, can also affect the heart tissue, called Loeffler endocarditis or sometimes loeffler endomyocarditis. In this case eosinophils accumulate in the endocardial layer of the heart tissue, causing inflammation and endocardial fibrosis, making it stiffer and again less compliant.
Acutely, it can cause pericardial effusion leading to cardiac tamponade and death. After healing, there may be fibrosis and adhesion of the pericardium with the heart leading to constriction of the heart and reduced cardiac function. Myocarditis: Here the muscle bulk of the heart gets inflamed. Inflamed muscles have reduced functional capacity.
“Carbonated water can be beneficial when it’s consumed as an alternative to sweetened carbonated beverages and energy drinks,” says Nichole Dandrea-Russert, M.S., R.D., author and plant ...
Myocarditis is the inflammation of the heart muscle; Endocarditis is the inflammation of the endocardium; Pancarditis, also called perimyoendocarditis, is the inflammation of the entire heart: the pericardium, the myocardium and the endocardium; Reflux carditis refers to a possible outcome of esophageal reflux [citation needed] (also known as ...
The most common cause of a myocardial infarction is the rupture of an atherosclerotic plaque on an artery supplying heart muscle. [41] [72] Plaques can become unstable, rupture, and additionally promote the formation of a blood clot that blocks the artery; this can occur in minutes. Blockage of an artery can lead to tissue death in tissue being ...
The main pathophysiology of heart failure is a reduction in the efficiency of the heart muscle, through damage or overloading. As such, it can be caused by a wide number of conditions, including myocardial infarction (in which the heart muscle is starved of oxygen and dies), hypertension (which increases the force of contraction needed to pump blood) and cardiac amyloidosis (in which misfolded ...
