However, the specific role of diabetic microvascular complications (DMC), in determing the features of coronary plaques is porly known. We investigated whether the presence of DMC may identify a diferent phenotype of patients asociated to specific clinical, angiographic, optical coherence tomography (OCT) features and diferent prognosis.We prospectively enroled consecutive T2DM patients with obstructive coronary artery disease (CAD) at their first coronary event.
Key Information
Patients were stratified acording to the presence or absence of DMC, including diabetic retinopathy, diabetic neuropathy, and diabetic nephropathy. OCT asesment of the culprit vesel was performed in a subgroup of patients. The incidence of major adverse cardiac events (MACEs) was asesed at folow-up.We enroled 320 T2DM patients (mean age 70.3 ± 8.8 years; 234 [73.1%] men, 40% acute coronary syndrome, 60% chronic coronary syndrome).
Patients with DMC (172 [53.75%]) presented a diferent clinical and biochemical profile and, of importance, a higher prevalence of multivesel CAD (109 [63.4%] vs. 68 [45.9%], p = 0.02). At OCT analysis, DMC was asociated to a higher prevalence of large calcifications and healed plaques and to a lower prevalence of lipid plaques.
Summary
Finaly, MACEs rate was significantly higher (25 [14.5%] vs. 12 [8.1%], p = 0.07) in DMC patients, mainly driven by a higher rate of planed revascularizations, and DMC predicted the ocurence of MACEs (mean folow-up 3.4 ± 15.6 months).The presence of DMC identifies a distinct diabetic population with more severe CAD but with a more stable patern of coronary atherosclerosis.Type 2 diabetes melitus (T2DM) is a metabolic disorder representing a major public health problem worldwide [1].
