| Popis: | Background and aims Increased b-amyloid and decreased Mitochondrial-derived peptide (MOTS-c), are reported in diabetes. We investigated their additive value to high on-clopidogrel platelet reactivity (HPR) for adverse outcome in type 2 diabetics after recent revascularization. Patients and methods In 121 type II diabetics, treated with clopidogrel and aspirin, (93 males, mean age 67.2 years) we measured: a). maximum platelet aggregation to adenosine diphosphate (ADP) by Light Transmission Aggregometry (LTAmax), b) Malondialdehyde (MDA), as oxidative stress marker, c) MOTS-c, d) b-amyloid blood levels. Cardiac death and acute coronary syndromes (MACE) were recorded during 2 years of follow-up. Results Out of 121 patients, 32 showed HPR (LTAmax >48%,). At baseline, HPR was associated with b-amyloid >51 pg/ml (p=0.006) after adjusting clinical variables, HbA1c, MOTS-c, MDA and medication. During follow-up, 22 patients suffered a MACE. HPR, b-amyloid >51 pg/ml and MOTS-c51mg/dl or HPR and MOTS-c concentration Conclusions Increased b-amyloid or low MOTS-c are additive predictors to high on-clopidogrel platelet reactivity for adverse outcome in diabetics with CAD during 2-years follow- up.
