Effect of diabetes mellitus on long-term outcomes after repeat drug-eluting stent implantation for in-stent restenosis

Impact of diabetes mellitus on clinical outcomes after first episode in-stent restenosis PCI: Results from a large registry

BACKGROUND

Diabetes mellitus (DM) is associated with a high rate of major adverse cardiac events (MACE) after de novo coronary artery percutaneous coronary intervention (PCI). Whether patients with DM undergoing PCI for in-stent restenosis (ISR) experience a similar heightened risk of MACE is not known. Hence, we sought to compare the clinical outcomes of patients with and without DM undergoing PCI for ISR.

METHODS

Patients undergoing first episode ISR PCI between January 2015 and December 2021 were included. The primary outcome of interest was MACE (all-cause death, myocardial infarction [MI], and target lesion revascularization [TVR]) at 1-year.

RESULTS

A total of 3156 patients (56.7% with DM) underwent PCI for ISR during the study period. Patients with DM were younger, more likely to be female, and had a higher prevalence of comorbidities. At 1-year follow-up, DM was associated with a higher rate of MACE (22.4% vs. 18.7%, unadjusted HR 2.03, 95%CI(1.27-3.25), p = 0.003). All-cause mortality and MI were significantly more frequent among people with DM at 1-year follow-up. The rate of TVR was similar in both groups (17.9% vs. 16.0%, unadjusted HR 1.14, 95%CI (0.94-1.37), p = 0.180). On adjusted analysis, there was no significant difference in the rate of MACE (AHR 1.07, 95%CI(0.90 - -1.29), p = 0.444), all-cause death (AHR 1.54, 95%CI(0.93-2.54), p = 0.095) or MI (AHR 1.10, 95%CI(0.74-1.63), p = 0.652).

CONCLUSION

ISR PCI in patients with DM was associated with a higher rate of MACE at 1-year follow-up. However, this increased risk was no longer significant after adjusting for baseline characteristics.

Unusual effects of PCSK9 E670G (rs505151) variation in patients with in-stent restenosis: Variable effects on restenosis risk according to concomitant chronic conditions

Recent reports showing that neo-atherosclerosis formation in stented coronary artery is characterized by the accumulation of lipid-laden macrophages within the neointima has strengthened the possibility that elevated low-density lipoprotein (LDL)-cholesterol may be a risk factor for in-stent restenosis (ISR). Protein Convertase Subtilisin/Kexin-9 (PCSK9) protein plays an important role in cholesterol metabolism by degrading of LDL receptors. The gain-of-function E670G (rs505151) mutation of the PCSK9 gene is a well-known genetic risk factor for hypercholesterolemia. This study evaluated for the first time the association of the E670G variation with the serum lipids, PCSK9 levels and concomitant diseases on the ISR risk. The study included 109 ISR, and 82 Non-ISR patients, based on the results of coronary angiography. Genotypes were determined using the real-time PCR and serum PCSK9 levels were measured by ELISA technique. The rare G allele of PCSK9 E670G (p < 0.05), hyperlipidemia (HL) (p < 0.001), and type 2 diabetes (T2DM) (p < 0.01) were associated with increased risk for ISR. In hyperlipidemic conditions, the E670G-G allele was associated with hypercholesterolemia and a higher risk of ISR (p < 0.001), while the E670G-AA genotype has been associated with a high prevalence of T2DM and hypertension. In addition, diabetic ISRs had higher serum PCSK9 levels (p < 0.05) and the E670G-AA genotype was associated with increased levels of diabetes markers. Our results indicated that the unusual effects of both G allele and AA genotype of the PCSK9 E670G variation may be involved in the risk of ISR in association with concomitant metabolic diseases.

Sirolimus-coated balloon in all-comer population of coronary artery disease patients: the EASTBOURNE DIABETES prospective registry

BACKGROUND

The outcomes of percutaneous coronary intervention (PCI) in diabetic patients are still suboptimal, and it is unclear if diabetic patients might derive a benefit from the use of drug-coated balloons.

AIMS

To evaluate the impact of diabetes mellitus on the outcomes of patients undergoing PCI with sirolimus-coated balloon (SCB) MagicTouch (Concept Medical, India).

METHODS

We conducted a subgroup analysis of the prospective, multicenter, investigator-initiated EASTBOURNE registry, evaluating the performance of MagicTouch SCB in patients with and without diabetes. The study primary endpoint was target lesion revascularization (TLR) at 12-month follow-up. Secondary clinical endpoints were major adverse clinical events (MACE), death, myocardial infarction (MI), and BARC 2-5 bleedings.

RESULTS

Among 2,083 enrolled patients, a total of 864 suffered from diabetes (41.5%). Patients with diabetes had a numerically higher occurrence of TLR (6.5% vs. 4.7% HR 1.38, 95%CI 0.91-2.08), all-cause death (3.8% vs. 2.6%, HR 1.81, 95%CI 0.95-3.46), and MACE (12.2% vs. 8.9%; HR 1.26 95%CI 0.92-1.74). The incidence of spontaneous MI was significantly higher among diabetic patients (3.4% vs. 1.5%, HR 2.15 95%CI 1.09-4.25); bleeding events did not significantly differ. The overall incidence of TLR was higher among in-stent restenosis (ISR) as compared to de-novo coronary lesions, irrespectively from diabetes status.

CONCLUSIONS

In the EASTBOURNE DIABETES registry, diabetic patients treated with the MagicTouch SCB did not have a significant increase in TLR when compared to non-diabetic patients; moreover, diabetic status did not affect the study device performance in terms of TLR, in both de-novo lesions and ISR.

The Best Strategy for the Black Hole Phenomenon between Intravascular Ultrasound and Optical Coherence Tomography

The black hole (BH) phenomenon is an intraluminal restenotic lesion. It was identified by intravascular ultrasound (IVUS) and optical coherence tomography (OCT) after intracoronary brachytherapy and drug-eluting stent implantation. Despite the similarity in the mode of action of brachytherapy and drug-eluting stent implantation, the BH phenomenon appears to be uncommon after drug-eluting stent implantation. Specifically, the BH phenomenon is better identified by OCT than by IVUS. Herein, we present a case of in-stent restenosis with suspected BH phenomenon on IVUS and confirmed by OCT.

SGLT-2 inhibitors and in-stent restenosis-related events after acute myocardial infarction: an observational study in patients with type 2 diabetes

BACKGROUND

No study evaluated the incidence of intra-stent restenosis (ISR)-related events in patients with type 2 diabetes (T2DM) and acute myocardial infarction (AMI) treated or not with sodium/glucose cotransporter 2 inhibitors (SGLT2i).

METHODS

We recruited 377 patients with T2DM and AMI undergoing percutaneous coronary intervention (PCI). Among them, 177 T2DM were treated with SGLT2 inhibitors before PCI. The primary outcome was major adverse cardiovascular events (MACE) defined as cardiac death, re-infarction, and heart failure related to ISR. In patients without ISR, minimal lumen area and minimal lumen diameter were assessed by coronary CT-angiography at 1-year follow-up.

RESULTS

Glycemic control was similar in SGLT2i-treated patients and never SGLT2i-users. The incidence of ISR-related MACE was higher in never SGLT2i-users compared with SGLT2i-treated patients, an effect independent of glycemic status (HR = 0.418, 95% CI = 0.241-0.725, P = 0.002) and observed also in the subgroup of patients with HbA1c < 7% (HR = 0.393, 95% CI = 0.157-0.984, P = 0.027). In patients without the event, the stent patency was greater in SGLT2i-treated patients compared with never SGLT2i-users at 1-year follow-up.

CONCLUSIONS

SGLT2i treatment in T2DM is associated with a reduced incidence of ISR-related events, independently of glycemic control.

In-hospital and 1-Year Outcomes of Repeated Percutaneous Coronary Intervention for In-stent Restenosis With Acute Coronary Syndrome Presentation

BACKGROUND

In-stent restenosis (ISR) is the Achilles' heel of percutaneous coronary intervention (PCI). There have been controversial data about outcomes of repeated PCI (redo-PCI) for ISR. This study aims to determine the predictors of major adverse cardiac events (MACE) in patients underwent redo-PCI for ISR.

METHODS

In this retrospective study, all patients with acute coronary syndrome who were underwent successful PCI for ISR at Tehran Herat Center (between 2004 and 2019) were eligible for inclusion. Patients with moderate to severe valvular heart disease and/or hematological disorders were excluded. Participants were divided into 2 groups based on the occurrence of the MACE [composite of cardiovascular death, myocardial infarction (MI), coronary artery bypass grafting, target vessel revascularization, and target lesion revascularization]; then, the study variables were compared between the 2 groups. Finally, the predictors of MACE were identified using Cox regression analysis.

RESULTS

Of 748 redo-PCI patients (mean age: 65.2 ± 10.1; 71.0% males), 631 patients had met the inclusion criteria. Fifty-four patients (9.8%) developed MACE within a 1-year follow-up period. Multivessel disease, primary PCI, Ad-hoc PCI, history of non-ST-segment elevation MI, and diabetes mellitus were independent predictors for MACE. In a subgroup analysis, 30 patients who experienced third PCI (target lesion revascularization/target vessel revascularization) were followed more as 1-year MACE. Among these patients, 14 MACEs were observed during the last follow-up (till June 2020).

CONCLUSIONS

Multivessel disease, primary PCI, and history of non-ST-segment elevation MI were the predictors of higher 1-year MACE, whereas Ad-hoc PCI and diabetes mellitus had a protective effect on MACE.

The Early Predictive Value of Circulating Monocytes and Eosinophils in Coronary DES Restenosis

Background

Monocytes and eosinophils are involved in intracoronary inflammatory responses, aggravating coronary artery plaque instability and in-stent restenosis (ISR).

Aims

To investigate an early prediction of ISR in patients undergoing stenting by circulating monocytes and eosinophils.

Methods

The single-center data of patients undergoing successful drug-eluting stents (DES) implantation from January 1, 2017 to April 30, 2020 were retrospectively analyzed. Of the 4,392 patients assessed, 140 patients with restenosis and 141 patients without restenosis were enrolled. A scheduled postoperative follow-up was proceeded in four sessions: 0-3 months, 3-6 months, 6-12 months, and >12 months. The hematological and biochemical measurement was collected. The angiographic review was completed within two postoperative years.

Results

Significant associations of monocyte count and percentage with ISR were evident [odds ratio (OR): 1.44, 95% CI: 1.23-1.68, P < 0.001; OR: 1.47, 95%CI: 1.24-1.74, P < 0.001, respectively], which began at 3 months postoperatively and persisted throughout the follow-up period. Eosinophil count and percentage were associated with ISR (OR: 1.22, 95%CI: 1.09-1.36, P = 0.001; OR: 1.23, 95%CI: 1.07-1.40, P = 0.003, respectively), with ISR most significantly associated with the baseline eosinophils. The receiver operating characteristic (ROC) curve analysis showed that the cutoff points of monocyte count and percentage in the ISR prediction were 0.46× 10⁹/L and 7.4%, respectively, and those of eosinophil count and percentage were 0.20 × 10⁹/L and 2.5%, respectively.

Conclusion

This study, with a long-term follow-up, first provides evidence that the elevated monocytes at three postoperative months and baseline eosinophils may be strong early predictors of ISR after drug-eluting stent implantation. Persistent elevation of monocytes may also be a signal of ISR after percutaneous coronary intervention (PCI).

Diabetes and restenosis

Restenosis, defined as the re-narrowing of an arterial lumen after revascularization, represents an increasingly important issue in clinical practice. Indeed, as the number of stent placements has risen to an estimate that exceeds 3 million annually worldwide, revascularization procedures have become much more common. Several investigators have demonstrated that vessels in patients with diabetes mellitus have an increased risk restenosis. Here we present a systematic overview of the effects of diabetes on in-stent restenosis. Current classification and updated epidemiology of restenosis are discussed, alongside the main mechanisms underlying the pathophysiology of this event. Then, we summarize the clinical presentation of restenosis, emphasizing the importance of glycemic control in diabetic patients. Indeed, in diabetic patients who underwent revascularization procedures a proper glycemic control remains imperative.

Angiographic performance of everolimus-eluting stents for the treatment of coronary in-stent restenosis in daily practice

OBJECTIVES

The present study aims to analyze the angiographic anti-restenotic performance of durable polymer everolimus-eluting stents (EES) for the treatment of in-stent restenosis (ISR) in daily practice.

BACKGROUND

Randomized data is available supporting the use of drug-coated balloons and drug-eluting stents for the treatment of ISR; however, additional real-world data including angiographic follow-up is needed.

METHODS

Patients who underwent EES-implantation for the treatment of drug-eluting stent ISR and attended for a 6-8 months angiographic surveillance were analyzed. Off-line assessment of the angiograms was conducted at a central quantitative coronary angiographic core laboratory.

RESULTS

A total of 426 patients with ISR were treated with EES and had undergone angiographic follow-up. The mean age was 66.8 ± 9.9 years and 27.5% suffered from diabetes. A total of 459 lesions were treated. The diameter stenosis decreased from 64.3 ± 19.1% (preprocedural) to 12.0 ± 6.4% (postprocedural). At 6-8 months angiographic follow-up, the in-segment diameter stenosis was 38.3 ± 21.7% and the in-stent late luminal loss was 0.54 ± 0.74 mm in the treated area analysis. The rate of recurrent binary restenosis was 25.7%.

CONCLUSIONS

In the setting of ISR, the angiographic anti-restenotic efficacy of stenting with EES is comparable to that observed in randomized clinical trials and less favorable than its performance in patients undergoing stenting for de novo disease.

Risk factors of in-stent restenosis in patients with diabetes mellitus after percutaneous coronary intervention: A protocol for systematic review and meta-analysis

BACKGROUND

Percutaneous coronary intervention (PCI) has become one of the effective methods for the treatment of coronary heart disease (CHD). However, it is easy to have in-stent restenosis (ISR), even cardiovascular events after PCI, which affects the therapeutic effects. The incidence of ISR in diabetes mellitus (DM) patients increased by 2 to 4 times. Early identification of the risk factors of ISR in DM patients after PCI may help clinical staff to prevent and intervene as soon as possible, so it is very important to improve the clinical outcomes of DM patients. Although scholars at home and abroad have studied and summarized the risk factors of ISR in DM patients after PCI, the conclusions are different. Therefore, in this study, meta-analysis was used to summarize the risk factors of ISR in DM patients after PCI, and to explore the characteristics of high-risk groups of ISR, thus providing reference for early identification and prevention of ISR.

METHODS

We will search related literature from PubMed, Embase, Cochrane Library, Web of Science, China Biology Medicine Database, China National Knowledge Infrastructure, China Science and Technology Journal Database, and Wanfang Database. Eligible studies will be screened based on inclusion criteria. Meanwhile, data extraction, risk of bias assessment, publication bias assessment, subgroup analysis, and quality assessment will be performed. Review Manager Version 5.3 software will be applied for data analysis. Each process is independently conducted by 2 researchers. If there is any objection, it will be submitted to a third researcher for resolution.

RESULTS

We will disseminate the findings of this systematic review and meta-analysis via publications in peer-reviewed journals.

CONCLUSIONS

The results of this analysis can be used to generate a risk prediction model and provide an intervention strategy for the occurrence of ISR in DM patients after PCI.

Impact of type II diabetes and gender on major clinical events after percutaneous coronary intervention

AIMS

Incidence of type 2 diabetes is markedly rising worldwide. Some studies suggest that the occurrence of major adverse cardiac events (MACE) after PCI is different in men and women, but data are conflicting.

METHODS

We studied patients with stable coronary artery disease (CAD) who underwent PCI between years 2000 and 2017. Patients with primary PCI were excluded. Drug-eluting stent (DES) and dual antiplatelet therapy were administered in all patients. We followed these patients for a mean of 68 months. MACE as a composite of coronary revascularization, myocardial infarction or cardiovascular death was sought in three time windows.

RESULTS

We studied 1799 patients, 29.6% of whom with diabetes. Women were 52%. In multivariate analyses, there were no significant differences in the risk of MACE between diabetic and non-diabetic patients, as well as between men and women, neither in different time windows, nor in the whole duration of follow-up. The components of MACE did not show any significant differences between diabetic and non-diabetic patients, as well as between the genders.

CONCLUSION

In our patients with stable CAD who received a modern therapeutic management after PCI, neither type 2 diabetes nor gender were associated with an excess risk of MACE.

Association between type D personality and in-stent restenosis in patients treated with percutaneous coronary intervention: A mediation analysis of dietary patterns

OBJECTIVE

Type D personality is a psychosocial risk factor for cardiovascular events and in-stent restenosis (ISR), but the mechanisms involved are not well understood. This study aimed to evaluate the effects of dietary patterns on the association between Type D personality and ISR in patients with coronary artery disease treated with percutaneous coronary intervention (PCI).

METHODS

This cross-sectional study comprised a total of 230 post-PCI patients who were assessed for Type D personality, depression, dietary patterns, physical activity and medication adherence via self-administered questionnaires. ISR was assessed by coronary angiography.

RESULTS

Type D personality (odds ratio [OR], 3.35; 95% confidence interval [CI], 1.05-10.71, p=0.042), low fruit intake (OR, 0.30; 95% CI, 0.12-0.68, p=0.008) and low vegetable intake (OR, 0.48, 95% CI, 0.27-0.91, p=0.021) were independent risk factors for ISR after adjustment for psychosocial, lifestyle and cardiovascular risk factors. Mediation analyses revealed that Type D personality had a significant direct effect on the development of ISR (p<0.05). In addition, nutrients in fruits and vegetables, including vitamin C, vitamin E and fiber, were important mediators of the relationship between Type D personality and ISR (p<0.05), the percentage of total indirect effect was 24.65%.

CONCLUSIONS

These findings suggested that the low intake of fruit and vegetables in Type D patients can predict ISR. The healthy dietary interventions to supply vitamin C, vitamin E and fiber may help to improve the prognosis in post-PCI patients with Type D personality.

In-stent restenosis of drug-eluting stents in patients with diabetes mellitus: Clinical presentation, angiographic features, and outcomes

OBJECTIVE

Diabetes mellitus (DM) is a risk factor for developing in-stent restenosis (ISR) following percutaneous coronary intervention (PCI). This study aimed to examine the presentation and outcomes of drug-eluting stent (DES) ISR in diabetics.

METHODS

This retrospective study included consecutive patients with clinical DES-ISR, who were hospitalized between January 2013 and December 2017 and who were grouped based on the presence or absence of DM. Clinical, angiographic features and 1-year outcomes [composite of death, myocardial infarction (MI), and repeat-target lesion revascularization] were compared.

RESULTS

Baseline characteristics of the DM group (n=109) were comparable to the non-DM group (n=82), except for the higher prevalence of hypertension and dyslipidemia in the former (60.6% vs. 46.3%, p=0.050; 74.4% vs. 57.8%, p=0.034, respectively). Clinical presentation was similar in both groups [acute coronary syndrome (ACS): 62.4% vs. 61%, p=0.843; MI: 34.9% vs. 34.1%, p=0.918). Diabetics had a higher prevalence of stent-edge restenosis (20.3% vs. 9.2%, p=0.019). The treatment strategy was similar in both groups with 52.3% in the DM group and 57.3% in the non-DM group undergoing PCI (p=0.513). One-year outcomes of the DM group were not different from those of the non-DM group (14.7% vs. 17.1%, p=0.683). Age [hazard ratio (HR), 1.05; 95% confidence interval (CI), 1.01-1.10; p=0.017], MI presentation (HR, 2.34; 95% CI, 1.14-4.80; p=0.020), and chronic kidney disease (CKD: HR, 2.82; 95% CI, 1.21-6.58; p=0.016) were predictors of poor outcomes.

CONCLUSION

Stent-edge restenosis is more common in diabetics. Clinical presentation and 1-year outcomes following DES-ISR are similar in diabetics and non-diabetics. Age, MI presentation, CKD, and not DM were predictors of poor outcomes following DES-ISR.

Comprehensive analysis of predictive factors for rapid angiographic stenotic progression and restenosis risk in coronary artery disease patients underwent percutaneous coronary intervention with drug-eluting stents implantation

BACKGROUND

This study aimed to explore the correlation of baseline, procedural, and postprocedure characteristics with the risk of rapid angiographic stenotic progression (RASP) and restenosis in coronary artery disease (CAD) patients after percutaneous coronary intervention (PCI) with drug-eluting stents implantation.

METHODS

Two hundred fourteen CAD patients underwent PCI with drug-eluting stents implantation were consecutively enrolled. Baseline, procedural, and postprocedure characteristics of patients were collected for analysis. Coronary angiography was performed to evaluate coronary stenosis before PCI and at 12 months after PCI. RASP of nontarget lesions and restenosis of stent-implanted target lesions were then assessed.

RESULTS

37.8% CAD patients occurred RASP at 12 months after PCI and compared to non-RASP group, RASP group presented with increased diabetes mellitus (DM) complication, higher concentration of serum uric acid (SUA), cardiac troponin I, N-terminal probrain natriuretic peptide, and high sensitive C-reactive protein (hs-CRP) as well as elevated occurrence of multivessel artery lesions. In addition, DM, SUA, hs-CRP, and multivessel artery lesions independently predicted high RASP risk. For restenosis, 21.0% patients occurred restenosis at 12 months after PCI, and patients in restenosis group presented with increased hypertension and DM occurrence, higher concentrations of SUA, LDL-C, and hs-CRP, as well as longer target lesion and length of stent in surgery compared to nonrestenosis group. Also, DM, SUA, LDL-C, hs-CRP, and length of target lesion independently predicted increased restenosis risk.

CONCLUSION

Diabetes mellitus, SUA, and hs-CRP are potential predictive factors for increased risk of both RASP and restenosis in CAD patients underwent PCI and drug-eluting stents implantation.

Impact of hyperuricemia on clinical outcomes after percutaneous coronary intervention for in-stent restenosis

Background

There have been limited data on the impact of hyperuricemia on long-term clinical outcomes after percutaneous coronary intervention (PCI) for in-stent restenosis (ISR).

Methods

From January 2009 to July 2015, 317 patients who underwent repeat PCI for ISR were divided into two groups: patients with normal serum uric acid (UA) levels (normal UA group) and patients with higher serum UA levels (higher UA group). The higher UA group included patients with serum UA levels > 6.8 mg/dL or patients who were taking anti-hyperuricemic medication.

Results

During a median follow-up period of 1088 days, the cumulative incidence rates of major adverse event (MAE), including a composite of all-cause death, non-fatal myocardial infarction, and any revascularization, were similar between the two groups (higher UA 36.4% vs. normal UA 29.9%, p = 0.389, log-rank p = 0.367). Follow-up angiographic data showed similar outcomes of late lumen loss (0.8 ± 0.9 mm vs. 0.8 ± 1.1 mm, p = 0.895) and binary restenosis rate (28.1% vs. 34.7%, p = 0.622). Multivariate Cox regression analysis indicated higher levels of low-density lipoprotein cholesterol (hazard ratio [HR] 1.011, 95% confidence interval [CI] 1.003–1.019, p = 0.006) and lower left ventricular ejection fraction (HR 0.972, 95% CI 0.948–0.996, p = 0.022), but not UA levels, to be the independent risk predictors of MAE.

Conclusion

Hyperuricemia is not associated with poor clinical outcomes after repeat PCI for ISR lesions.

Prognostic Value of Type D Personality for In-stent Restenosis in Coronary Artery Disease Patients Treated With Drug-Eluting Stent

OBJECTIVE

To evaluate the predictive value of Type D personality on in-stent restenosis (ISR) rates at 1 and 2 years post-percutaneous coronary intervention (PCI) in patients with coronary artery disease.

METHODS

Consecutive patients with coronary artery disease who underwent PCI for drug-eluting stents (n = 173) completed the Type D Scale-14 (DS14) at baseline. Follow-up coronary angiographic evaluation was routinely planned at 1 and 2 years after the procedure.

RESULTS

Follow-up coronary angiography was performed in 159 and 112 patients at 1 and 2 years post-PCI, respectively. On multivariate analysis, Type D personality was found to be an independent predictor of ISR at 1 year (odds ratio [OR] = 2.67, 95% confidence interval [CI] = 1.16-6.14, p = .021) and 2 years (OR = 4.92, 95% CI = 1.82-9.60, p = .017) after adjusting for cardiovascular risk factors. However, Type D did not predict ISR when the analysis was performed using the interaction between negative affectivity and social inhibition. The main effect of negative affectivity emerged as a significant risk factor for 1-years (OR = 4.22, 95% CI = 1.18-7.86, p = .034) and 2-year ISR (OR = 6.93, 95% CI = 2.25-11.50, p = .016).

CONCLUSIONS

In this study, Type D personality was an independent predictor of ISR at 1 and 2 years post-PCI; the association strengthened with time. The negative affectivity component seems to drive the relationship between Type D and ISR over time. Our findings provide new insights into the mechanisms involved in the association between Type D and adverse clinical outcomes of PCI.
