Alert! COVID-19 Is Linked With Cardiovascular Diseases

Researchers at The University of Texas Health Science Center at Houston (UTHealth) studied that in individuals with underlying heart diseases, COVID-19 can cause deadly consequences and in individuals, without cardiovascular diseases, COVID-19 can cause serious heart injuries.

They found that COVID-19 (caused by SARS-CoV-2) can cause a severe respiratory illness that may further lead to lung failure and in some cases it may also cause death. But the effects of COVID-19 on the heart are less known.

The study was published in the journal JAMA cardiology.


According to Mohammad Madjid, the research leader and professor of cardiology at McGovern Medical School at UTHealth, novel coronavirus (COVID-19) may cause damage to the cardiac muscles of patients with no underlying cardiovascular diseases. Patients with underlying cardiovascular diseases are at high risk of heart injury. However, the heart muscle of patients with or without heart disease can be affected by COVID-19.

The research authors clarify that arrhythmias, development of heart failure, acute coronary syndrome and aggravation of cardiac disease may result from viral infections according to the research from past influenza and coronavirus epidemics.

American College of Cardiology issued a clinical bullet that highlights that individuals with heart diseases have a 10.5% case fatality ratio due to novel coronavirus and patients with high blood pressure and heart diseases are more likely to catch an infectious disease.

The severity of infectious diseases is much high in Individuals over the age of sixty-five and requires good critical care to deal with symptoms.

Madjid visits patients at the UT Physicians Multispecialty—Bayshore clinic and found that patients with severe symptoms are more likely to face heart diseases due to COVID-19. Patients with underlying cardiovascular diseases have a high inflammatory response to novel coronavirus.

The study authors highlight that dysfunction of multiple organs, respiratory infection or septic shock that lead to death are considered as critical cases.

In January 2020 the first case of COVID-19 caused by coronavirus was identified. Coronavirus has emerged in the wet market of Wuhan, China and it was declared as a global pandemic by the World Health Organization on March 11, 2020. Symptoms of COVID-19 can appear two to fourteen days after exposure to the virus.

Shortness of breath, fever, and cough are some common symptoms of coronavirus and less common symptoms include headache, sore throat, muscle pain, and nasal congestion. Viral load is very high in both asymptomatic and symptomatic patients but the spread of viruses from an asymptomatic patient is higher.

In humans severe illness like Middle East Respiratory Syndrome (MERS-CoV) and Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV) was caused by previously identified coronaviruses. Middle East Respiratory Syndrome coronavirus was 1st identified in Saudi Arabia in 2012 and by 2019, over twenty-four hundred and ninety-four cases and eight hundred fifty-eight deaths have been confirmed in twenty-six countries. However, Severe Acute Respiratory Syndrome coronavirus was discovered in 2002 in southern China and by 2003, over eight thousand deaths have been confirmed in twenty-nine countries.

Data shows that cardiovascular diseases like myocardial infarction and coronary syndrome resulted from Severe Acute Respiratory Syndrome coronavirus (SARS-CoV).

Researchers are trying to test antivirals for the treatment of patients and to find vaccines for COVID-19. at the same time, researchers suggest individuals consult with the paramedic staff. Individuals should seek advice about the influenza vaccine.

Individuals who are at high risk of COVID-19 should consult with primary care physicians about the pneumonia vaccine. However, these vaccines don’t protect against COVID-19 but can help prevent viral infections. The study concludes that novel coronavirus can cause severe heart injuries in patients with or without underlying heart diseases.
