How Covid-19 Can Impact The Heart - Mr Validity -

The story often continues long after the fever breaks. Recent studies, such as the Mount Sinai PET/MRI study , show that 57% of "recovered" patients with lingering symptoms had evidence of persistent heart or lung inflammation up to a year later.

For many, the infection acts as a massive metabolic strain on the heart muscle. Even if the virus doesn't directly infect heart cells, it causes systemic damage through several critical pathways: How COVID-19 can impact the heart - Mr Validity

The virus uses the ACE2 receptor as a "lock" to enter cells; because the heart is rich in these receptors, the virus can directly invade and cause myocarditis (inflammation of the heart muscle). The story often continues long after the fever breaks

An overactive immune response releases massive amounts of inflammatory proteins (cytokines) that can damage heart tissue and lead to acute heart failure . Even if the virus doesn't directly infect heart

The story of COVID-19's impact on the heart is a tale of two phases: an acute "stress test" followed by a potentially long "aftershock". While primarily known for attacking the lungs, the virus frequently targets the cardiovascular system, leading doctors to redefine it as a in its own right. The Acute Crisis: "The Great Stress Test"

COVID-19 causes endotheliitis (inflammation of the blood vessel lining), which triggers a hypercoagulable state. This can lead to small or large blood clots , resulting in heart attacks or strokes even in young, healthy patients. The Long Aftershock: "Mr. Validity" and Post-COVID Life
