Higher genetically predicted fat-free mass index is inversely associated with the risk of atrial fibrillation, ischaemic stroke, and abdominal aortic aneurysm.

Maintaining or increasing fat-free mass (muscle) may offer protective benefits against atrial fibrillation, ischaemic stroke, and abdominal aortic aneurysm. Incorporate resistance training to build muscle, while also managing fat mass to optimize cardiovascular health.

There was significant or suggestive evidence that genetically predicted fat-free mass index was inversely associated with atrial fibrillation, ischaemic stroke, and abdominal aortic aneurysm.

Why this rating

MR design provides causal inference, but the associations are described as 'significant or suggestive', indicating some uncertainty.
