In moderately obese men, elevated circulating free fatty acid (FFA) levels drive the accumulation of triglycerides within the myocardium and epicardial fat, a process that precedes left ventricular hypertrophy and overload.
For individuals with obesity, high levels of free fatty acids in the blood can lead to fat storage inside the heart muscle, even before heart function declines. This suggests that managing overall metabolic health and fatty acid availability is crucial for preventing early cardiac structural changes.
The accumulation of triglyceride in and around the myocardium of moderately obese individuals is significant, and it is related to FFA exposure, generalized ectopic fat excess, and peripheral vascular resistance. These changes precede LV overload and hypertrophy.
Why this rating
Small sample size (n=9) and cross-sectional observational design limit causal inference, though the mechanistic link is strongly supported by animal literature cited.

- Initial treatment for type 2 diabetes should be a combination of metformin and either an SGLT-2 inhibitor or a GLP-1 receptor agonist to achieve cardiorenal protection, rather than monotherapy or older agents like sulfonylureas.Strong
