![]() Myocarditis has been reported as one of the potential side effects from the mRNA vaccine, affecting young healthy individuals. Currently the focus has shifted from the host of organ damage related to the infection to potential side effects of the vaccine. Despite continuous viral mutations and the identification of weaker variants, the severity of the infections has been mild, with many patients being either asymptomatic or recovering at home. The rush development of the 3 vaccines and their expedited approval have led to inoculation of millions of patients around the world, leading to a containment of the disease.

If you ever think you’re having a heart attack, call triple zero (000) immediately. It’s important you don’t neglect your heart health even amid the pandemic. An Australian study found a 21 per cent reduction in cardiac surgery at Sydney’s Royal Prince Alfred Hospital between March and June 2020. One study found global hospital admissions for heart attacks have decreased between 40 per cent and 50 per cent. This makes long-term heart damage more likely. Longer delays between the onset of the symptoms and hospital treatment are being reported in countries including England, Italy and China. This includes for both urgent and routine care of heart disease. Many people have been reluctant to seek medical attention amid the pandemic. But if you have had myocarditis or pericarditis in the past six months then speak with your doctor or cardiologist. The vast majority of people with heart conditions are safe to get vaccinated. Nevertheless, if you experience any change in symptoms after having a COVID vaccine, including chest pain, an irregular heartbeat, fainting or shortness of breath, you should seek prompt medical attention. The benefits of vaccination against COVID far outweigh the potential risks of these generally mild conditions. Recovery from this heart inflammation is generally good. ![]() There have been no reported deaths associated with this vaccine side effect in Australia. Of the 5.6 million Pfizer vaccine doses administered to Australians so far, there have only been 111 cases of suspected (not confirmed) heart inflammation reported up to August 1. This seems to be most common in males under 30 and after the second vaccine dose.īut this is very rare. There’s also a link between mRNA COVID vaccines and a rare side effect of heart inflammation (myocarditis and pericarditis). Scientists have discovered a link between the Oxford-AstraZeneca vaccine and a rare blood clotting syndrome. The good news is two doses of either the Pfizer or AstraZeneca vaccines remains effective in preventing Delta complications. It also found Delta was spreading most commonly in younger people. It’s the variant responsible for lockdowns in New South Wales, Victoria and Queensland.Īlthough data is still emerging, it may cause more severe disease, and anecdotally may increase the chances of heart complications.Ī Scottish study found the risk of hospital admission from COVID was around double in those with Delta variant compared to the Alpha variant (which originated in the UK). The Delta variant, first identified in India in October 2020, is highly transmissible. Of roughly 3,700 study participants, over 90 per cent reported their recovery lasted more than eight months. One study on long COVID, published in July, found common cardiovascular symptoms include heart palpitations, fast heart rate, slow heart rate, chest pain, visible bulging veins, and fainting. Persistent symptoms from the virus, called “long COVID”, have been reported in about 10–30 per cent of people who’ve contracted COVID. Our understanding of how COVID causes heart inflammation and injury to the heart muscle is becoming clearer, though there’s more to learn. ![]() Inflammation from COVID can also cause blood clotting, which can block a heart or brain artery causing a heart attack or stroke.ĬOVID can also cause abnormal heart rhythms, blood clots in the legs and lungs, and heart failure. This can impact the heart, causing myocarditis and pericarditis – inflammation of the heart muscle or outer lining of the heart. The SARS-CoV-2 virus can directly invade the body causing inflammation.
