Covid 19 and its cardiovascular effects.

COVID-19 pandemic is mainly related with the pulmonary problems initially but now as the pandemic is growing it is observed that almost all organ systems of the body are affected. Up to 20-30% patients who are admitted in Covid hospitals are showing cardiovascular involvement. Severity of cardiovascular disease in a COVID-19 patient depends whether a patient is having pre-existing cardiac disease or not. Patients with pre-existing cardiac disease have more severe infection and associated mortality. Severe COVID-19 infection shows close association with myocardial damage and various arrythmias. The cardiovascular involvement occurs by either engagement directly with the angiotensin converting enzyme 2 or indirectly by the effect of inflammatory mediators which are generated as a result of viral-host response to infection. The COVID-19 disease is said to produce a wide spectrum of affliction ranging between even asymptomatic patient to Cardiovascular syndrome. Even after recovering from COVID-19 patients can reappear in the hospital with cardiomyopathies and arrythmias.
