Studies suggest that people with COVID-19 are 55% more likely to suffer a major adverse cardiovascular event,...
By Thor Christensen, American Heart Association News (Irina Shatilova/iStock via Getty Images) People hospitalized with COVID-19 may have an increased risk for heart damage, but not so much the type of inflammation previous research suggested, according to a new study. Early in the pandemic, several studies suggested many COVID-19 survivors experienced heart damage even if...

Nancy A. Melville May 17, 2022 A new study highlights the importance of avoiding both exogenous hyperthyroidism and exogenous hypothyroidism to decrease cardiovascular risk and death among patients receiving thyroid hormone treatment. “Our findings suggest that clinicians should make every effort to maintain euthyroidism in patients on thyroid hormone treatment, regardless of underlying cardiovascular risk,...
