Researchers explored the "prolonged physiological impact of COVID-19" in a research letter published in JAMA Network Open.

Patients presenting with an acute myocardial infarction during the start of the COVID-19 pandemic faced delays in care and a higher risk of developing heart failure.

In a new statement, the CDC, American Heart Association and several other healthcare organizations highlighted the continued importance of vaccination. 

The patient, a 78-year-old female, began showing signs of a negative reaction within 20 hours. 

“Given the potential morbidity of COVID-19 infection even in younger adults, the risk-benefit decision for vaccination remains highly favorable," researchers wrote.

The study's authors used more than 34,000 ECGs to train and test their model, publishing their findings in Mayo Clinic Proceedings.

“Clinicians and policymakers should consider that strategies which improve cardiovascular health may also improve outcomes for people following COVID-19," one researcher said.
