Colombo<\/div>\n<div><\/div>\n<div>7 Key Facts Everyone Should Know:<\/div>\n<div><\/div>\n<div><span> 1. Heart failure with preserved ejection fraction (HFpEF) is now more common than HFrEF \u2014 and obesity plays a bigger role in HFpEF.<\/span><\/div>\n<div><span> 2. Though obesity is a known risk factor for heart disease, studies have shown that overweight heart failure patients sometimes have better outcomes \u2014 a puzzling pattern called the \u201cobesity paradox.\u201d<\/span><\/div>\n<div><span> 3. This paradox may be due to the limitations of BMI, which doesn\u2019t distinguish between fat vs muscle or show where fat is stored.<\/span><\/div>\n<div><span> 4. Fat Distribution and Risk<\/span><\/div>\n<div><span> \u2022 Visceral fat (around organs) is more harmful than subcutaneous fat due to proinflammatory effects.<\/span><\/div>\n<div><span> \u2022 Metrics like waist circumference, waist-to-hip ratio, and waist-to-height ratio better reflect risk.<\/span><\/div>\n<div><span> \u2022 UK NICE recommends waist-to-height ratio over BMI.<\/span><\/div>\n<div><span> \u2022 Imaging (CT, MRI) offers precise fat distribution data but lacks standardized cutoffs.<\/span><\/div>\n<div><span> 5. Sarcopenia in HF<\/span><\/div>\n<div><span> \u2022 Present in ~20% of HF patients; strong predictor of mortality.<\/span><\/div>\n<div><span> \u2022 Defined by:<\/span><\/div>\n<div><span> 1. Low muscle strength (e.g., grip strength)<\/span><\/div>\n<div><span> 2. Low muscle quantity\/quality<\/span><\/div>\n<div><span> 3. Poor physical performance<\/span><\/div>\n<div><span> \u2022 Preferred assessment: DEXA scan (with validated sex-specific cutoffs).<\/span><\/div>\n<div><span> \u2022 Other tools: BIA, CT, MRI.<\/span><\/div>\n<div><span> 6. A major meta-analysis of over 36,000 HF patients found:<\/span><\/div>\n<div><span> \u2022 Low muscle mass = higher mortality<\/span><\/div>\n<div><span> \u2022 High subcutaneous fat = potentially protective<\/span><\/div>\n<div><span> \u2022 Visceral fat = worse outcomes\u00a0<\/span><\/div>\n<div><span> 7. New weight-loss drugs (like semaglutide and tirzepatide) are effective but can also lead to loss of muscle mass \u2014 up to 25% of the total weight lost \u2014 which may be harmful in older or frail patients with HF.<\/span><\/div>\n<div><\/div>\n<div>Takeaway: BMI is an outdated tool for assessing health risk in heart failure. A deeper look at muscle mass, fat distribution, and functional strength gives a much clearer picture of patient risk \u2014 and should guide future care.<\/div>\n<div><\/div>\n<div><a href=\"https:\/\/www.jacc.org\/doi\/10.1016\/j.jchf.2025.05.003\">https:\/\/www.jacc.org\/doi\/10.1016\/j.jchf.2025.05.003<\/a><\/div>\n<div><\/div>\n","protected":false},"excerpt":{"rendered":"<p>Is It Time to Replace BMI?
