Had Covid? Have you had these things ruled out? No? This is a *short* list of clinically-provable conditions in Long Covid that some orgs and other interests want you to think is (not-biomedically validated in Long Covid) MECFS instead. Many of these issues demand medical attention. Many of them have viable treatments that could help ppl right now. Many of them cause sudden death...we haven't seen any of that, have we? Dementia & Vascular Dementia - If you've had Covid, you have a 41% higher risk of dementia and a 77% higher risk of vascular dementia. This is anything but MECFS "cognitive PEM". Thrombotic microangiopathy - Microclots throughout small blood vessels severely limit oxygen and nutrient delivery to tissues. When you exert yourself, tissues cannot get enough oxygen to meet even minimal increased demands. This creates oxygen debt and toxic metabolite buildup that triggers a systemic crash - the delayed, prolonged exhaustion and multi-system symptoms can resemble MECFS. With organs already barely functioning due to poor blood flow, any extra activity pushes the whole system over the edge, causing a collapse that takes days or weeks to recover from. Heart failure (including HFpEF) - Heart Failure with Preserved Ejection Fraction is particularly insidious. Standard echos can look "normal" but the heart can't properly relax and fill. Causes exercise intolerance, shortness of breath, and fatigue that worsens with activity. Sound familiar? Interstitial lung disease/fibrosis - Scarring of lung tissue causing progressive breathing difficulty and exercise limitation that can seem like PEM. Chronic thromboembolic disease - Clots organizing in lungs, causing progressive right heart strain. The "PEM-like Sx" are driven by the heart-lung unit hitting a wall - any exertion beyond minimal activity causes systemic oxygen starvation and cardiac strain that takes days to recover from. Unlike deconditioning, rest doesn't improve capacity because the structural blockages remain. Diaphragmatic dysfunction - Nerve or muscle damage to breathing muscles, causing "air hunger" and exercise limitation that can seem like PEM. Pulmonary hypertension - High blood pressure in lung arteries causes severe fatigue and breathlessness with exertion that can be misdiagnosed as PEM. Often missed without right heart catheterization. Silent myocardial ischemia - Reduced blood flow to heart muscle without typical chest pain. Can present as fatigue, exercise intolerance, PEM. Aortic stenosis or other valve disease - Can develop from Covid infection and cause exercise intolerance that is often dismissed as deconditioning and/or PEM. Microvascular dysfunction - Covid can cause small vessel disease affecting coronary, cerebral, or peripheral circulation can cause fatigue, exercise intolerance, and cognitive issues that worsen with exertion. Pulmonary embolism (including microemboli) - Covid can cause blood clots in lungs, especially smaller chronic ones, that can cause progressive exercise intolerance and fatigue. Myocarditis or pericarditis - Post-viral heart inflammation can cause exercise intolerance, fatigue, and chest symptoms that worsen with activity. This requires proper cardiac imaging and biomarker testing to diagnose, but can be mistaken as PEM. POTS and dysautonomia - Postural Orthostatic Tachycardia Syndrome and other autonomic dysfunctions can cause profound fatigue and post-exertional symptoms, but require specific testing and treatment, quite contrary to how Yale's Akiko Iwasaki & Harlan Krumholz run POTS "studies". Cerebral hypoperfusion - Reduced blood flow to the brain can cause cognitive dysfunction, fatigue, and exercise intolerance that is misclassed as PEM. This can result from Covid vascular damage, autonomic dysfunction, or other mechanisms that result in symptoms that sound a lot like PEM. Small vessel cerebrovascular disease - Microinfarcts or white matter changes from vascular damage could cause cognitive impacts and fatigue that can be mislabeled as MECFS. Neuroinflammation - Direct viral invasion or immune-mediated inflammation in the nervous system could cause symptoms attributed to PEM: Hypersensitivity to noise, light, and temperature; memory problems, difficulty with attention, persistent forgetfulness, difficulty focusing, slowed information processing, etc. that appear similar to "cognitive PEM". Cerebral venous sinus thrombosis - Blood clots in brain's drainage system. Can cause headaches, cognitive issues, and fatigue that can be misdiagnosed as MECFS, before catastrophic events occur. Progressive atherosclerosis - Covid accelerates plaque formation. Carotid or coronary artery disease developing years faster than normal. This Covid-induced condition present with MECFS-like symptoms through a mechanism of exertion-triggered ischemia and delayed recovery. Vasculitis - Covid can cause blood vessel inflammation throughout body. Can affect any organ system and progress to organ failure if untreated. Patients experience malaise, fatigue, and generalized weakness. Covid-induced systemic vasculitis can produce MECFS-like symptoms through multi-organ hypoperfusion and inflammatory exhaustion that worsen with exertion. COVID-19 causes brain and neurological damages that produce symptoms remarkably similar to the generic Dx checklist MECFS, isn't that convenient? Especially when doctors & ins companies won't cover the scans required to prove your brain damages, vascular damages, dementias, etc. Insurance companies LOVE the medical-care-ending-zero-treatment MECFS Dx. It's so much cheaper to tell 400M ppl to pace than to develop targeted treatments for them, isn't it? This is a short list conditions that can be caused by Covid, are found in Long Covid, and that require medical treatment, not to be written off as MECFS.
