Impact of Coronary Artery Disease and Diabetes Mellitus on the Long-Term Follow-Up in Patients after Retrograde Recanalization of the Femoropopliteal Arterial Region

الملخص EN

The most relevant comorbidities in patients with peripheral artery disease (PAD) are coronary artery disease (CAD) and diabetes mellitus (DM).

However, data of long-term follow-up of patients with chronic total occlusion (CTO) are scarce.

The aim of the study was to assess the impact of CAD and DM on long-term follow-up patients after superficial femoral artery (SFA) CTO retrograde recanalization.

In this study, eighty-six patients with PAD with diagnosed CTO in the femoropopliteal region and at least one unsuccessful attempt of antegrade recanalization were enrolled in 2 clinical centers.

Mean time of follow-up in all patients was 47.5 months (±40 months).

Patients were divided into two groups depending on the presence of CAD (CAD group: n=45 vs.

non-CAD group: n=41) and DM (DM group: n=50 vs.

non-DM group: n=36).

In long-term follow-up, major adverse peripheral events (MAPE) occurred in 66.6% of patients with CAD vs.

36.5% of patients without CAD and in 50% of patients with DM vs.

55% of non-DM subjects.

There were no statistical differences in peripheral endpoints in both groups.

However, there was a statistically significant difference in all-cause mortality: in the DM group, there were 6 deaths (12%) (P value = 0.038).

To conclude, patients after retrograde recanalization, with coexisting CTO and DM, are at higher risk of death in long-term follow-up.
