Long COVID's Hidden Impact: Affecting 1 in 5 with Heart Risks

A new AI tool developed by Mass General Brigham has identified long COVID in 22.8% of patients, significantly higher than previous estimates. By analyzing health records from nearly 300,000 patients, the tool uses 'precision phenotyping' to distinguish long COVID symptoms from other conditions, improving diagnostic accuracy by 3%. This approach may enhance understanding and treatment of long COVID, while addressing biases in traditional diagnostic methods. The study highlights the potential for AI to improve healthcare outcomes and research into long COVID's genetic and biochemical factors.
