Obese heart disease patients who are inactive have a 30% higher death risk compared to overweight inactive patients, while active obese patients have a 19% higher risk compared to active overweight patients.
Scientific Claim
Obesity (BMI ≥30 kg/m²) is associated with a 30% higher risk of all-cause mortality in coronary artery disease patients with low physical activity levels compared to those with BMI 25–30 kg/m², which is higher than the 19% risk observed in patients with high physical activity levels.
Original Statement
“The HR for obesity, compared to BMI 25–30 kg/m2, was 1.30 (95% CI: 1.17, 1.45) in patients with low physical activity and 1.19 (95% CI: 1.04, 1.35) in patients with high physical activity.”
