  • Who has Covid-19?
  • Covid-19 infection is more severe in elderly and men, and in people with hypertension, diabetes (diabetes), heart failure, cardiovascular disease, smoking and overweight. People with these risks are also more likely to get infected. The infection has a more severe course in cardiac patients compared to those with chronic lung disease. Cardiac involvement is observed in 20-40% of patients with Covid-19 pneumonia. While the mortality rate of patients with cardiac involvement reaches 40%, the mortality rate in patients without cardiac involvement is at the level of 4.5%.


  • What is the mortality rate of cardiovascular patients in Covid-19 cases?
  • Considering the mortality rates due to Covid-19 among chronic diseases, it is seen that cardiovascular diseases take the first place with 10.5%. Cardiovascular diseases are followed by diabetes with 7.3%, chronic lung disease with 6.3%, hypertension with 6% and cancer with 5.6%.
  • What is the result of the effects of Covid-19 on the cardiovascular system?
  • Multiple effects of Covid-19 infection on the cardiovascular system are observed. As a result of these effects, in patients;
  • -Myocarditis, a heart muscle disease that reduces the pumping power of the heart and causes heart failure.
  • -Heart attack, stroke, triggered by an increase in the tendency of the blood to clot,
  • -Pulmonary embolism and pulmonary hypertension as a result of coagulation in the venous system,
  • -Severe signs of right heart failure, shock,
  • -With the effect of drugs such as hydroxychloroquine used in the treatment, rhythm disturbances and cardiac arrest are observed.


  • Does it have a long-term effect on heart patients?
  • Long-term cardiac effects of Covid-19 have also begun to be observed. It has been observed that patients who are caught and recovered with the virus have the risk of developing heart disease in the long term and a decrease in the pumping power of the heart. In addition, it has been shown that the increase in the tendency of blood clotting and the inflammatory process (inflammation) continues for a long time after the healing from the disease. This leads to increased risks such as heart attack, heart failure and sudden death. Even if the patient gets healed from Covidien-19, continuity of some cardiovascular diseases in the future may be occur.
  • Covid-19 patients with heart disease, especially heart failure and cardiovascular disease, should be followed regularly by a cardiologist, and they should continue to treat heart failure and rhythm disorders, especially with blood-thinner drugs.
