Myocarditis
The inflammation of the myocardium is medically termed myocarditis. The necrosis of myocyte cells is usually present for some types of myocarditis (Palaskas et al., 2020). One such type is lymphocytic myocarditis, usually caused by viruses and autoimmune responses. Other types of myocarditis include neutrophilic, reperfusion type, granulomatous, and eosinophilic (Ammirati et al., 2018). The inflammation is mainly seen as a diffuse process of the myocardium. However, there are cases of focal myocarditis, which happen in the right or left ventricles of the heart (Neilan et al., 2018). In the United States (US), approximately ten to twenty people are diagnosed with myocarditis out of one hundred thousand people annually (Golpour et al., 2021). The essay will address and apply the key terms that aid in communicating the pathophysiology of myocarditis to the patients. These terms will include the etiology, epidemiologic data, symptoms, and risk factors associated with myocarditis.
There are four major causes of myocarditis. The first is the presence of infectious agents that may originate from any part of the body (Neilan et al., 2018). The second cause is post-viral autoimmunity, which usually results after a viral attack. The third cause is the mediation of autoimmune response, as seen in the case of lupus myocarditis and giant-cell myocarditis (Ammirati et al., 2018). The fourth cause is a result of drug hypersensitivity.
Myocarditis patients usually show different symptoms, ranging from mild and non-specific signs to severe and more articulate symptoms. Severe symptoms include palpitations, death, and...
