Coronavirus disease 2019 (COVID-19) is an acute infectious respiratory disease caused by a newly discovered coronavirus (SARS-CoV-2). The virus can cause a range of symptoms, ranging from mild illness to pneumonia. The most common symptoms of the disease are fever, dry cough, sore throat, tiredness, a rash on the skin, or discolouration of fingers or toes, diarrhoea, conjunctivitis, loss of taste or smell, and headaches. When an infected person coughs, sneezes, or exhales. This is transmitted through a droplet which is too heavy to hang in the air, and quickly fall on floors or surfaces. Most people who fall sick with COVID-19 will experience mild to moderate symptoms and recover without special treatment. In severe cases, difficulty in breathing and deaths can occur.
COVID-19 linked to heart damage
Three-quarters of recovered COVID-19 patients had signs of enduring heart damage months after their initial infection.
The study, published in the journal JAMA Cardiology, involved 100 adults ages 45 to 53 in Germany who had recently recovered from COVID-19 seems to be infected from heart disease. On MRI scans taken more than two months after their diagnosis, about three-quarters of these patients, showed signs of heart abnormalities, including inflammation of the heart muscle, or myocarditis. Troponin is a protein found in heart cells that are released into the blood when the heart muscle is damaged. According to the University of Rochester Medical Center, many patients also had detectable levels of a protein in their blood called troponin that can indicate heart injury, such as damage after a heart attack.
Although initially recognized mainly as a lung infection, COVID-19 has now been linked with damage to multiple other organs in the body, including the brain and heart. According to the National Heart, Lung, and Blood Institute, the findings represent imprecise in patients’ heart health. The heart abnormalities were seen in the study occasionally occur with other respiratory diseases such as influenza and mild cases of heart inflammation without symptoms and certainly get better on their own. The findings are potentially worrisome because heart inflammation and damage may give rise to heart failure, a potentially life-threatening condition that occurs when the heart muscle can’t pump enough blood to meet the body’s normal demands. Yet there is no direct evidence for the consequence in the development of heart failure.
In a study, were 67 out of 100 patients were not hospitalized, and most of these people experienced mild or moderate symptoms such as high blood pressure, diabetes, or asthma. Even though patients were followed up with an MRI scan about two to three months after their initial diagnosis. At this time, about one-third of patients experiencing ongoing COVID-19 symptoms, such as shortness of breath and general exhaustion, and few patients had heart palpitations and chest pain, but none thought they had a heart problem related to COVID-19. The presence of heart abnormalities was not related to the severity of the study participants’ COVID-19 illness or whether they had underlying conditions. Overall, 78% of recovered COVID-19 patients showed signs of some type of heart abnormality.
