چکیده انگلیسی


- We analyze the impact of MPO on plaque progression by intravascular ultrasound.
- Increasing MPO level contributes to plaque progression in diabetics.
- LDL-C lowering results in less progression in diabetics with low MPO level.
- High-dose statin prevents plaque progression in diabetics with low MPO level.
- These benefits are diminished in diabetics with high MPO level.

ObjectiveWhile inflammation has been proposed to contribute to the adverse cardiovascular outcome in diabetic patients, the specific pathways involved have not been elucidated. The leukocyte derived product, myeloperoxidase (MPO), has been implicated in all stages of atherosclerosis. The relationship between MPO and accelerated disease progression observed in diabetic patients has not been studied.MethodsWe investigated the relationship between MPO and disease progression in diabetic patients. 881 patients with angiographic coronary artery disease underwent serial evaluation of atherosclerotic burden with intravascular ultrasound. Disease progression in diabetic (n = 199) and non-diabetic (n = 682) patients, stratified by baseline MPO levels was investigated.ResultsMPO levels were similar in patients with and without diabetes (1362 vs. 1255 pmol/L, p = 0.43). No relationship was observed between increasing quartiles of MPO and either baseline (p = 0.81) or serial changes (p = 0.43) in levels of percent atheroma volume (PAV) in non-diabetic patients. In contrast, increasing MPO quartiles were associated with accelerated PAV progression in diabetic patients (p = 0.03). While optimal control of lipid and the use of high-dose statin were associated with less disease progression, a greater benefit was observed in diabetic patients with lower compared with higher MPO levels at baseline.ConclusionsIncreasing MPO levels are associated with greater progression of atherosclerosis in diabetic patients. This finding indicates the potential importance of MPO pathways in diabetic cardiovascular disease.
