Obesity and insulin resistance drive elevated plasma Plasminogen Activator Inhibitor-1 (PAI-1) levels primarily through adipocyte overexpression of PAI-1, mediated by cytokines (TNF-alpha, TGF-beta) and insulin, thereby increasing cardiovascular thrombotic risk.
Excess body fat, particularly visceral fat, actively contributes to heart disease risk by secreting proteins that promote blood clots. This is not just 'storage'; it is an active hormonal process. Losing weight, even moderately, can significantly lower these clot-promoting proteins, reducing cardiovascular risk.
PAI-1 is dramatically upregulated in obesity... elevated PAI-1 levels and thrombotic disease... the key role played by the adipocyte... multiple cytokines, hormones, and growth factors may be involved... TNF-alpha, insulin/proinsulin, and TGF-beta... stimulate PAI-1 biosynthesis by the adipocyte
Why this rating
The paper is a review citing multiple animal models (ob/ob mice) and human clinical studies showing consistent correlations and causal links via specific mediators.

- 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
- For patients with specific monogenic obesity syndromes (leptin deficiency, POMC/PCSK1/LEPR mutations), targeted pharmacotherapy (recombinant leptin or setmelanotide) is highly effective and should be prioritized, unlike in polygenic obesity.Strong
- Continued weekly administration of 2.4 mg subcutaneous semaglutide prevents weight regain and promotes further weight loss in adults with overweight or obesity, whereas switching to placebo results in significant weight regain.Strong
