Organ damage from the acute infection can explain a part of the symptoms, but long COVID is also observed in people where organ damage seems to be absent. [44] Several hypotheses have been put forward explaining long COVID, including: [3] blood clotting and endothelial dysfunction in the blood vessels
“A COVID-19 infection can directly damage the heart,” Dr. Harlan Krumholz said.
Long COVID is an often severe multisystem disease with a large set of symptoms. There are likely various, possibly coinciding, causes. [76] Organ damage from the acute infection can explain a part of the symptoms, but long COVID is also observed in people where organ damage seems to be absent. [77]
During COVID-19, the other indirect mechanisms thought to contribute to myocarditis include: oxygen supply-demand mismatch to the heart muscle leading to myocardial (heart muscle) injury; microvascular thrombi, or blood clots in the small blood vessels of the heart causing injury; the systemic hyperinflammatory state in Covid-19 leading to ...
However, if a heart valve is damaged, the bacteria can attach themselves to the valve, resulting in infective endocarditis. Additionally, in individuals with weakened immune systems, the concentration of bacteria in the blood can reach levels high enough to increase the probability that some will attach to the valve.
The majority of treatment is aimed at preserving heart function and treating heart failure symptoms. [3] Light chain (AL-CM) Treatment: Since the cause of this subtype of cardiac amyloidosis is the excessive production of free light chains, the major goal of treatment is the reduction in concentration of light chains. [5]
The coronavirus can damage the heart, ... The coronavirus can damage the heart, according to a major new study which found abnormalities in the heart function of more than half of patients.
The heart valve changes seen with moderate and intermittent use can result in permanent damage and life-threatening heart problems if use of the causative drug is increased or continued, however longitudinal studies of former patients suggest that the damage will heal over time to some extent at least.
