Influence of preprocedural glycemic control on clinical outcomes of endovascular therapy in diabetic patients with lower extremity artery disease: an analysis from a Korean multicenter retrospective registry cohort.

ABSTRACT:

Background

The influence of intensive glucose control in diabetic patients on the macrovascular outcomes is controversial. Thus, this study aimed to elucidate the effect of preprocedural hemoglobin A1c (HbA1c) on clinical outcomes after endovascular therapy for lower extremity artery disease (LEAD) in diabetic patients.

Methods

Diabetic patients were enrolled from the retrospective cohorts of a Korean multicenter endovascular therapy registry and were divided according to the HbA1c level during index admission into the optimal (< 7.0%) or suboptimal (≥ 7.0%) glycemic control groups. The primary endpoints were major adverse limb events (MALE, a composite of major amputation, minor amputation, and reintervention).

Results

Of the 1103 patients enrolled (897 men, mean age 68.2 ± 8.9 years), 432 (39.2%) were classified into the optimal glycemic control group and 671 (60.8%) into the suboptimal glycemic control group. In-hospital events and immediate procedural complications were not different between the two groups. The suboptimal group showed a trend towards a higher incidence of MALE than the optimal group (log-rank p = 0.072). Although no significant differences were found between the two groups in terms of overall survival or amputation, the risk of reintervention was significantly higher in the suboptimal group (log-rank p = 0.048). In the multivariate Cox regression model, suboptimal glycemic control was one of the independent predictors for reintervention. When our data were analyzed according to the initial presentation, suboptimal preprocedural HbA1c significantly increased the incidence of MALE compared with optimal preprocedural HbA1c only in patients with intermittent claudication.

Conclusion

In diabetic patients undergoing endovascular therapy for LEAD, suboptimal preprocedural HbA1c is associated with an increased risk of adverse limb events, especially in patients with intermittent claudication. Further prospective research will be required to validate the role of more intensive glycemic control on the reduction of adverse limb events in diabetic patients undergoing endovascular therapy for LEAD.

Project description:BackgroundEndovascular therapy offers an alternative for treating femoropopliteal (FP) and infrapopliteal (IP) lesions related to occlusive lower extremity artery disease. Despite numerous trials, the effectiveness of restenosis prevention using local drug delivery devices remains a topic of debate.ObjectivesAn updated systematic review and network meta-analysis was conducted. Our overall aim was to summarize the most recent clinical evidence regarding endovascular approaches for FP and IP atherosclerotic lesions.MethodsWe conducted a search for randomized trials in the MEDLINE database, and extracted data related to clinical endpoints. Our primary focus was on the rate of major adverse events (MAEs), including mortality, amputation, and target lesion revascularization (TLR). A multiple treatment network meta-analysis supplemented with component network analyses was performed to examine the impact of combined treatment.ResultsOur search yielded 33 randomized controlled trials encompassing 5766 patients. This included 19 studies focused on femoropopliteal and 14 on IP lesions, accounting for 3565 and 2201 patients, respectively. Drug-coated balloons (DCBs) and drug-eluting stents (DESs) displayed a reduced MAE risk in comparison to plain old balloon angioplasty (POBA)-RR for DCB: 0.64 (95% CI: 0.52-0.77) and for DES: 0.71 (95% CI: 0.51-0.99). The bare-metal stent (BMS) group manifested the most substantial MAE risk, being 59% higher relative to the DCB cohort (BMS vs. DCB RR: 1.59; 95% CI: 1.03-2.47). For FP lesions, DES was the standout performer, curtailing MAE risk by 55% relative to POBA. Within IP lesions, DES mitigated the MAE risk by 25% versus POBA. DCB did not exhibit any notable MAE reduction when pitted against POBA.ConclusionIn FP arteries, both DESs and DCBs yielded significantly diminished MAEs, thus outpacing other techniques. Regarding IP arteries, only DESs resulted in significantly fewer MAEs. In alignment with contemporary research, our findings revealed no signs of elevated mortality in patients undergoing treatment with drug-eluting apparatuses.

Project description:BackgroundAltered adipokine secretion in dysfunctional adipose tissue facilitates the development of atherosclerotic diseases including lower extremity peripheral artery disease (PAD). Asprosin is a recently identified adipokine and displays potent regulatory role in metabolism, but the relationship between asprosin and lower extremity PAD remains uninvestigated.Methods33 type 2 diabetes mellitus (T2DM) patients (DM), 51 T2DM patients with PAD (DM + PAD) and 30 healthy normal control (NC) volunteers were recruited and the blood samples were collected for detecting the circulatory asprosin level and metabolomic screening. RNA sequencing was performed using the aorta tissues from the type 2 diabetic db/db mice and human umbilical vein endothelial cells (HUVECs) were treated with asprosin to determine its impact on the endothelial-to-mesenchymal transition (EndMT).ResultsThe circulating levels of asprosin in DM + PAD group were significantly higher than that of NC group and the DM group. Circulating asprosin level was remarkably negatively correlated with ankle-brachial index (ABI), even after adjusting for age, sex, body mass index (BMI) and other traditional risk factors of PAD. Logistic regression analysis revealed that asprosin is an independent risk factor for PAD and receiver-operator characteristic (ROC) curve determined a good sensitivity (74.5%) and specificity (74.6%) of asprosin to distinguish PAD. Data from metabolomics displayed a typical characteristics of de novo amino acid synthesis in collagen protein production by myofibroblasts in patients with PAD and activation of TGF-β signaling pathway appeared in the aortic tissue of db/db mice. Asprosin directly induces EndMT in HUVECs in a TGF-β-dependent manner as TGF-β signaling pathway inhibitor SB431542 erased the promotional effect of asprosin on EndMT.ConclusionsElevated circulatory asprosin level is an independent risk factor of lower extremity PAD and might serve as a diagnostic marker. Mechanistically, asprosin directly induces EndMT that participates in vascular injury via activation of TGF-β signaling pathway. Trial registration This trial was registered at clinicaltrials.gov as NCT05068895.
