President Donald Trump underwent a preventive magnetic resonance imaging (MRI) in October. The results showed that his cardiovascular system is in excellent condition with no signs of narrowing of arteries, deterioration of blood flow or abnormalities in the heart or blood vessels[1][2]. Doctor Sean Barbabella stated that all major organs appear healthy and well perfused, with normal parameters[1][2]. The reason for the non-standard examination was not explained, which raised questions about the completeness of the information[1][2]. University professor Bruce Davidson speculates about a possible past stroke based on circumstantial evidence, but official reports do not confirm this[3]. The White House diagnosed chronic venous insufficiency and rejected conjectures about dementia or neurological diseases[3]. Trump has been taking aspirin for a long time at a dose of 325 mg per day[3]. An earlier case of meningitis in the US caused by faulty steroid injections killed 11 people and infected 119 in ten states[4].
