Quantitative flow ratio versus fractional flow reserve for Heart Team decision-making in multivessel disease: the randomised, multicentre DECISION QFR trial.

BACKGROUND: Vessel-level physiological data derived from pressure wire measurements are one of the important determinant factors in the optimal revascularisation strategy for patients with multivessel disease (MVD). However, these may result in complications and a prolonged procedure time. AIMS: The feasibility of using the quantitative flow ratio (QFR), an angiography-derived fractional flow reserve (FFR), in Heart Team discussions to determine the optimal revascularisation strategy for patients with MVD was investigated. METHODS: Two Heart Teams were randomly assigned either QFR- or FFR-based data of the included patients. They then discussed the optimal revascularisation mode (percutaneous coronary intervention [PCI] or coronary artery bypass grafting [CABG]) for each patient and made treatment recommendations. The primary endpoint of the trial was the level of agreement between the treatment recommendations of both teams as assessed using Cohen's kappa. RESULTS: The trial included 248 patients with MVD from 10 study sites. Cohen's kappa in the recommended revascularisation modes between the QFR and FFR approaches was 0.73 [95% confidence interval {CI} : 0.62-0.83]. As for the revascularisation planning, agreements in the target vessels for PCI and CABG were substantial for both revascularisation modes (Cohen's kappa=0.72 [95% CI: 0.66-0.78] and 0.72 [95% CI: 0.66-0.78], respectively). The team assigned to the QFR approach provided consistent recommended revascularisation modes even after being made aware of the FFR data (Cohen's kappa=0.95 [95% CI:0.90-1.00]). CONCLUSIONS: QFR provided feasible physiological data in Heart Team discussions to determine the optimal revascularisation strategy for MVD. The QFR and FFR approaches agreed substantially in terms of treatment recommendations.

Prasugrel Monotherapy After Percutaneous Coronary Intervention for Chronic Coronary Syndrome: Insights From ASET Pilot Studies.

Background: The ASET (Acetyl-Salicylic Elimination Trial) pilot studies recently investigated P2Y12 inhibitor monotherapy without aspirin immediately after percutaneous coronary intervention (PCI) in Brazil and Japan. Objectives: This comparative analysis of the 2 ASET pilot studies aimed to summarize clinical outcomes and assess geographic and ethnic differences in baseline demographics and procedures. Methods: Patients undergoing successful platinum-chromium everolimus-eluting stent implantation for chronic coronary syndrome were included. Following the index PCI, patients received prasugrel monotherapy with a maintenance dose of 10 mg/day in Brazil and 3.75 mg/day in Japan. The primary ischemic endpoint was the composite of cardiac death, spontaneous target vessel myocardial infarction, or definite stent thrombosis. The primary bleeding endpoint was Bleeding Academic Research Consortium types 3 and 5 bleeding at up to 3 months. Results: Of 409 enrollments, 3-month follow-up was completed in 406 patients. Mean age was 64.3 ± 8.4 years, and 73% were men. Overall, post-TIMI flow grade 3 was achieved in 99.8%. Intravascular imaging for poststent optimization was used in 16.8% and 99.6% of treated lesions in Brazil and Japan, respectively. The primary ischemic and bleeding endpoints occurred in the same patient (0.2%). No stent thrombosis events occurred. Conclusions: Prasugrel monotherapy following PCI was safe and feasible in selected low-risk chronic coronary syndrome patients after optimal platinum-chromium everolimus-eluting stent implantation regardless of the ethnic and geographic differences in baseline demographics, procedures, and prasugrel dosage. Randomized controlled trials will be needed to compare P2Y12 inhibitor monotherapy without aspirin with the current standard of care.

The Absorb GT1 Bioresorbable Vascular Scaffold System　- 5-Year Post-Market Surveillance Study in Japan.

BACKGROUND: The 1-year clinical outcomes of the Absorb GT1 Japan post-market surveillance (PMS) suggested that an appropriate intracoronary imaging-guided bioresorbable vascular scaffold (BVS) implantation technique may reduce the risk of target lesion failure (TLF) and scaffold thrombosis (ST) associated with the Absorb GT1 BVS. The long-term outcomes through 5 years are now available.Methods and Results: This study enrolled 135 consecutive patients (n=139 lesions) with ischemic heart disease in whom percutaneous coronary intervention (PCI) with the Absorb GT1 BVS was attempted. Adequate lesion preparation, imaging-guided appropriate sizing, and high-pressure post-dilatation using a non-compliant balloon were strongly encouraged. All patients had at least 1 Absorb GT1 successfully implanted at the index procedure. Intracoronary imaging was performed in all patients (optical coherence tomography: 127/139 [91.4%] lesions) and adherence to the implantation technique recommendations was excellent: predilatation, 100% (139/139) lesions; post-dilatation, 98.6% (137/139) lesions; mean (±SD) post-dilatation pressure, 18.8±3.5 atm. At 5 years, the follow-up rate was 87.4% (118/135). No definite/probable ST was reported through 5 years. The cumulative TLF rate was 5.1% (6/118), including 2 cardiac deaths, 1 target vessel-attributable myocardial infarction, and 3 ischemia-driven target lesion revascularizations. CONCLUSIONS: Appropriate intracoronary imaging-guided BVS implantation, including the proactive use of pre- and post-balloon dilatation during implantation may be beneficial, reducing the risk of TLF and ST through 5 years.

Sodium-Glucose Cotransporter-2 Inhibitors in Heart Failure with Malnutrition, Frailty, Sarcopenia, or Cachexia.

(1) Background: In patients with heart failure (HF) and impaired nutritional status or decreased muscle mass, sodium-glucose cotransporter-2 inhibitors (SGLT2is) may worsen these conditions and result in poor prognosis, especially worsening of frailty. We aimed to investigate the relationship between SGLT2is and clinical outcomes, including frailty-related events, in patients with HF and malnutrition, frailty, sarcopenia, or cachexia. (2) Methods: In this retrospective observational cohort study, a global federated health research network provided data on patients with HF and malnutrition, frailty, sarcopenia, or cachexia from January 2016 to December 2021. We investigated the incidence of the composite endpoint of death or frailty-related events within one year. (3) Results: Among 214,778 patients included in the analysis, 4715 were treated with SGLT2is. After propensity score matching, 4697 patients in the SGLT2is group were matched with 4697 patients in the non-SGLT2is groups. The incidence of the composite endpoint, mortality, and frailty-related events was lower in the SGLT2is group than in the non-SGLT2is group (composite endpoint, 65.6% versus 77.6%, p < 0.001; mortality, 17.4% vs. 35.5%, p < 0.001; frailty-related events, 59.4% vs. 64.3%, p < 0.001). (4) Conclusions: Patients with HF and malnutrition, frailty, sarcopenia, or cachexia had a high incidence of death and frailty-related events. SGLT2is were associated with a lower incidence of these events.

Pacemaker implantation in a patient with isolated persistent left superior vena cava using a delivery catheter: a case report.

Background: Persistent left superior vena cava (PLSVC) with absent right superior vena cava, also termed 'isolated PLSVC', is extremely rare. Permanent pacemaker implantation in patients with isolated PLSVC is often difficult by the usual subclavian approach due to the unique anatomy. With the advent of delivery catheters in recent years, implantation using the same system has been reported. Case summary: A 47-year-old woman with symptomatic sick sinus syndrome was admitted to our institution for permanent pacemaker implantation. Preprocedural cardiac multidetector computed tomography (MDCT) showed isolated PLSVC. We performed pacemaker implantation successfully via the left subclavian approach, using the C315 delivery catheter system. The leads were stable on chest radiography, and the sensing and capture thresholds were unchanged. After the procedure, we integrated the delivery catheter images with cardiac MDCT using Ziostation, and they were well matched with the fluoroscopic images. At the 1-month follow-up, the patient was free of heart failure symptoms and had decreased levels of N-terminal prohormone of brain natriuretic peptide. Discussion: The C315 delivery catheter system was considered an option for permanent pacemaker implantation in patients with isolated PLSVC. When performing permanent pacemaker implantation in patients with unusual venous anatomy, integrating the delivery catheter images with cardiac MDCT allows for appropriate preoperative catheter selection.

Geographic disparity of pathophysiological coronary artery disease characteristics: Insights from ASET trials.

BACKGROUND: The geographical disparity in the pathophysiological pattern of coronary artery disease (CAD) among patients undergoing percutaneous coronary intervention (PCI) is unknown. OBJECTIVES: To elucidate the geographical variance in the pathophysiological characteristics of CAD. METHODS: Physiological indices derived from angiography-based fractional flow reserve pullbacks from patients with chronic coronary syndrome enrolled in the ASET Japan (n = 206) and ASET Brazil (n = 201) studies, which shared the same eligibility criteria, were analysed. The pathophysiological patterns of CAD were characterised using Murray law-based quantitative flow ratio (µQFR)-derived indices acquired from pre-PCI angiograms. The diffuseness of CAD was defined by the µQFR pullback pressure gradient index. RESULTS: Significant functional stenoses pre-PCI (µQFR ≤0.80) were more frequent in ASET Japan compared to ASET Brazil (89.9% vs. 67.5%, p < 0.001), as were rates of a post-PCI µQFR <0.91 (22.1% vs. 12.9%, p = 0.013). In the multivariable analysis, pre-procedural µQFR and diffuse disease were independent factors for predicting a post-PCI µQFR <0.91, which contributed to the different rates of post-PCI µQFR ≥0.91 between the studies. Among vessels with a post-PCI µQFR <0.91, a consistent diffuse pattern of CAD pre- and post-PCI occurred in 78.3% and 76.7% of patients in ASET Japan and Brazil, respectively; only 6.3% (Japan) and 10.0% (Brazil) of vessels had a major residual gradient. Independent risk factors for diffuse disease were diabetes mellitus in ASET Japan, and age and male gender in Brazil. CONCLUSIONS: There was geographic disparity in pre-procedural angiography-based pathophysiological characteristics. The combined pre-procedural physiological assessment of vessel µQFR and diffuseness of CAD may potentially identify patients who will benefit most from PCI.

Impact of Dapagliflozin on the Renal Function and Damage in Patients with Heart Failure with a Reduced Ejection Fraction.

Objective Whether or not the initial dip in the glomerular filtration rate (GFR) after the initiation of sodium-glucose co-transporter 2 inhibitors (SGLT2is) is associated with renal tubular injury in patients with heart failure with a reduced ejection fraction (HFrEF) is unclear. We therefore investigated the relationship between changes in the estimated GFR (eGFR) and urine N-acetyl-ß-D-glucosaminidase (uNAG) after the initiation of dapagliflozin in patients with HFrEF. Methods We prospectively investigated 89 patients with HFrEF who were newly started on dapagliflozin 10 mg/day. Changes in the eGFR and uNAG-to-creatinine ratio (uNAG/Cre) were evaluated at 2 weeks and 2 months after the initiation of dapagliflozin. Results The eGFR was decreased at 2 weeks but had not declined further by 2 months. The uNAG/Cre was increased at 2 weeks but had not increased further by 2 months. There was no correlation between the changes in the eGFR and uNAG/Cre (r=-0.022, p=0.853 at 2 weeks and r=0.078, p=0.538 at 2 months). The relative change in the systolic blood pressure, hematocrit, plasma volume, and N-terminal pro-brain natriuretic peptide (NT-proBNP) were correlated with the relative change in the eGFR. In a multiple linear regression analysis, the relative change in the eGFR at 2 weeks was significantly associated with NT-proBNP, and the relative change in the uNAG/Cre was significantly associated with the use of loop diuretics and the relative change in urine osmolality at 2 weeks. Conclusion A transient decrease in the eGFR after the initiation of dapagliflozin in patients with HFrEF was not generally associated with renal tubular injury and might have been the result of hemodynamic alteration.

Guillain-Barré syndrome after percutaneous coronary intervention and transcatheter aortic valve implantation.

Guillain-Barré syndrome (GBS) usually develops after preceding infection, but cardiac surgery can also occasionally cause GBS. Currently, cardiac catheterizations have already become common therapeutic options for heart diseases, but there have been no reports of GBS occurrence after that. Herein, we present a rare case in which GBS occurred following catheterization. An 85-year-old-man with sudden onset chest pain was rushed to our hospital and diagnosed with ST-elevated myocardial infarction. He underwent emergent percutaneous coronary intervention (PCI) to left anterior descending artery, but he still had exertional chest pain. Echocardiography revealed severe aortic stenosis (AS) and our heart team considered AS was the cause of symptom and decided to perform and transcatheter aortic valve implantation (TAVI), 11 days after the PCI. However, 5 days after the TAVI procedure, he presented with symmetrical muscular weakness of extremities. Cranial magnetic resonance imaging showed no significant lesion. Based on several signs including albuminocytologic dissociation in cerebrospinal fluid examination, demyelinating polyneuropathy in nerve conduction study, positive anti-ganglioside antibody, and the lack of preceding infection, he was diagnosed with GBS triggered by cardiac catheterizations. We administered high-dose intravenous immunoglobulin therapy and his motor strength gradually improved, finally discharged with full motor strength after 7 months rehabilitation. Learning objective: •Cardiac surgery has been already reported as a non-infectious risk factor of Guillain-Barré syndrome (GBS) in previous literatures, and cardiac catheterization such as percutaneous coronary intervention and transcatheter aortic valve implantation, which were relatively less invasive procedure, may be a potential risk factor for GBS occurrence as well.•If a patient complains of progressive, symmetrical neurological symptoms after cardiac catheterization, GBS should be considered as the possible cause, and nerve conduction study and cerebrospinal fluid examination may be helpful for the diagnosis.

Deep Learning Models for Predicting Left Heart Abnormalities From Single-Lead Electrocardiogram for the Development of Wearable Devices.

BACKGROUND: Left heart abnormalities are risk factors for heart failure. However, echocardiography is not always available. Electrocardiograms (ECGs), which are now available from wearable devices, have the potential to detect these abnormalities. Nevertheless, whether a model can detect left heart abnormalities from single Lead I ECG data remains unclear.Methods and Results: We developed Lead I ECG models to detect low ejection fraction (EF), wall motion abnormality, left ventricular hypertrophy (LVH), left ventricular dilatation, and left atrial dilatation. We used a dataset comprising 229,439 paired sets of ECG and echocardiography data from 8 facilities, and validated the model using external verification with data from 2 facilities. The area under the receiver operating characteristic curves of our model was 0.913 for low EF, 0.832 for wall motion abnormality, 0.797 for LVH, 0.838 for left ventricular dilatation, and 0.802 for left atrial dilatation. In interpretation tests with 12 cardiologists, the accuracy of the model was 78.3% for low EF and 68.3% for LVH. Compared with cardiologists who read the 12-lead ECGs, the model's performance was superior for LVH and similar for low EF. CONCLUSIONS: From a multicenter study dataset, we developed models to predict left heart abnormalities using Lead I on the ECG. The Lead I ECG models show superior or equivalent performance to cardiologists using 12-lead ECGs.

Clinical impacts of CT-derived fractional flow reserve under insurance reimbursement: Results from multicenter, prospective registry.

BACKGROUND: Although computed tomography-derived fractional flow reserve (FFRCT) has been reimbursed in a few countries, its impacts on daily practice of coronary artery diseases are not fully elucidated. We evaluated the clinical impacts of FFRCT under the real Japanese insurance reimbursement. METHODS: In the multicenter prospective registry: DYNAMIC-FFRCT study, a total of 410 patients who underwent FFRCT analysis under reimbursement were prospectively enrolled at 6 Japanese sites from October 2019 to November 2021. Coronary CT angiography and FFRCT findings, treatment plans, and 90-day outcomes were recorded. The primary endpoint was the redirection rate from the tests that might be expected without FFRCT [invasive coronary angiography (ICA)-selected group, myocardial perfusion single photon emission CT (MPS)-selected group, optimal medical therapy (OMT)-selected group, and others-selected group] to those that were actually performed based on FFRCT. RESULTS: ICA could be avoided in 39.5 % in the ICA-selected group (N = 233). In particular, in 94.3 % of patients with an FFRCT value of >0.80, additional examinations, such as ICA, were avoided. In addition, in the MPS-selected group (N = 133), 92.6 % had no additional tests with FFRCT > 0.80, while only 2 cases with FFRCT ≤ 0.80 underwent additional MPS examination. On the contrary, 33.3 % of the OMT-selected group (N = 33) had FFRCT ≤ 0.80. Approximately, 35 % medical cost reduction was also finally expected. CONCLUSION: Introduction of FFRCT could not only reduce unnecessary ICA and be a test that replaces the conventional non-invasive functional assessment modality but also result in medical cost reduction even when used under real Japanese insurance reimbursement.

Preprocedural physiological assessment of coronary disease patterns to predict haemodynamic outcomes post-PCI.

BACKGROUND: Even with intracoronary imaging-guided stent optimisation, suboptimal haemodynamic outcomes post-percutaneous coronary intervention (PCI) can be related to residual lesions in non-stented segments. Preprocedural assessment of pathophysiological coronary artery disease (CAD) patterns could help predict the physiological response to PCI. AIMS: The aim of this study was to assess the relationship between preprocedural pathophysiological haemodynamic patterns and intracoronary imaging findings, as well as their association with physiological outcomes immediately post-PCI. METHODS: Data from 206 patients with chronic coronary syndrome enrolled in the ASET-JAPAN study were analysed. Pathophysiological CAD patterns were characterised using Murray law-based quantitative flow ratio (µQFR)-derived indices acquired from pre-PCI angiograms. The diffuseness of CAD was defined by the pullback pressure gradient (PPG) index. Intracoronary imaging in stented segments after stent optimisation was also analysed. RESULTS: In the multivariable analysis, diffuse disease - defined by the pre-PCI µQFR-PPG index - was an independent factor for predicting a post-PCI µQFR <0.91 (per 0.1 decrease of PPG index, odds ratio 1.57, 95% confidence interval: 1.07-2.34; p=0.022), whereas the stent expansion index (EI) was not associated with a suboptimal post-PCI µQFR. Among vessels with an EI ≥80% and post-PCI µQFR <0.91, 84.0% of those vessels had a diffuse pattern preprocedure. There was no significant difference in EI between vessels with diffuse disease and those with focal disease. The average plaque burden in the stented segment was significantly larger in vessels with a preprocedural diffuse CAD pattern. CONCLUSIONS: A physiological diffuse pattern preprocedure was an independent factor in predicting unfavourable immediate haemodynamic outcomes post-PCI, even after stent optimisation using intracoronary imaging. Preprocedural assessment of CAD patterns could identify patients who are likely to exhibit superior immediate haemodynamic outcomes following PCI.

Effect of dapagliflozin on ventricular repolarization in patients with heart failure with reduced ejection fraction.

Whether sodium-glucose cotransporter-2 inhibitors (SGLT2is) reduce ventricular arrhythmias and sudden cardiac death is controversial. Ventricular repolarization heterogeneity is associated with ventricular arrhythmias; however, the effect of SGLT2is on ventricular repolarization in patients with heart failure with reduced ejection fraction (HFrEF) has not been fully investigated. We prospectively evaluated 31 HFrEF patients in sinus rhythm who were newly started on dapagliflozin 10 mg/day. Changes in QT interval, corrected QT interval (QTc), QT dispersion (QTD), corrected QTD (QTcD), T peak to T end (TpTe), TpTe/QT ratio, and TpTe/QTc ratio were evaluated at 1-year follow-up. QT interval, QTc interval, QTD, QTcD, TpTe, and TpTe/QTc ratio decreased significantly at 1-year follow-up (427.6 ± 52.6 ms vs. 415.4 ± 35.1 ms; p = 0.047, 437.1 ± 37.3 ms vs. 425.6 ± 22.7 ms; p = 0.019, 54.1 ± 11.8 ms vs. 47.6 ± 14.7 ms; p = 0.003, 56.0 ± 11.2 ms vs. 49.4 ± 12.3 ms; p = 0.004, 98.0 ± 15.6 ms vs. 85.5 ± 20.9 ms; p = 0.018, and 0.225 ± 0.035 vs. 0.202 ± 0.051; p = 0.044, respectively). TpTe/QT ratio did not change significantly (0.231 ± 0.040 vs. 0.208 ± 0.054; p = 0.052). QT interval, QTD, and TpTe were significantly reduced 1 year after dapagliflozin treatment in patients with HFrEF. The beneficial effect of dapagliflozin on the heterogeneity of ventricular repolarization may contribute to the suppression of ventricular arrhythmias.Registry information https://center6.umin.ac.jp/cgi-open-bin/ctr/ctr_view.cgi?recptno=R000049428 .

SYNTAX Score and 1-Year Outcomes in the OPTIVUS-Complex PCI Study Multivessel Cohort.

BACKGROUND: The optimal revascularization strategy in patients with multivessel disease and intermediate SYNTAX score (SS) has not been fully elucidated. This study aimed to investigate the clinical outcomes of optimal intravascular ultrasound (IVUS)-guided percutaneous coronary intervention (PCI) stratified by SS. METHODS: This was a substudy of the OPTIVUS-Complex PCI study Multivessel Cohort, which aimed to meet the prespecified criteria for optimal stent expansion after IVUS-guided PCI. A total of 1,005 patients were divided into 3 groups according to SS: low, ≤22; intermediate, 23 to 32; and high, ≥33. The primary end points were major adverse cardiac and cerebrovascular events (MACCE) defined as a composite of death, myocardial infarction, stroke, or coronary revascularization. RESULTS: The cumulative 1-year incidence of the primary end point was significantly higher in patients with high SS than in those with intermediate or low SS (25.0%, 10.9%, and 9.5%, respectively; p = 0.003). This difference was mainly caused by the incidence of coronary revascularization. In the multivariable Cox proportional hazards models, the excess risk of patients with high versus low SS remained significant for the primary end point (hazard ratio 3.19, 95% confidence interval 1.65 to 6.16, p <0.001), whereas the excess risk of patients with intermediate versus low SS was no longer significant (hazard ratio 1.20, 95% confidence interval 0.72 to 2.01, p = 0.46). CONCLUSIONS: After IVUS-guided multivessel PCI, patients with intermediate SS had a similar 1-year risk of MACCE to that of patients with low SS, whereas patients with high SS had a higher 1-year risk of MACCE than those with low SS.

Single-Session Versus Staged Multivessel Optimal IVUS-Guided PCI in Patients With CCS or NSTE-ACS.

Background: There are no studies comparing single-session vs staged multivessel intravascular ultrasound (IVUS)-guided percutaneous coronary intervention (PCI) in patients with chronic coronary syndrome (CCS) or non-ST-segment-elevation acute coronary syndrome (NSTE-ACS). Objectives: The authors aimed to compare single-session vs staged multivessel IVUS-guided PCI in patients with CCS or NSTE-ACS. Methods: The OPTIVUS-Complex PCI study multivessel cohort was a prospective multicenter single-arm trial enrolling 1,021 patients with CCS or NSTE-ACS undergoing multivessel PCI including left anterior descending coronary artery using IVUS aiming to meet the prespecified OPTIVUS criteria for optimal stent expansion. We compared single-session vs staged multivessel PCI. The primary endpoint was a composite of death, myocardial infarction, stroke, or any coronary revascularization. Results: There were 246 patients (24.1%) undergoing single-session multivessel PCI, and 775 patients (75.9%) undergoing staged multivessel PCI. There was a wide variation in the prevalence of single-session multivessel PCI across the participating centers. The staged multivessel PCI group more often had complex coronary anatomy such as 3-vessel disease, chronic total occlusion, and calcified lesions requiring an atherectomy device compared with the single-session multivessel PCI group. The rates of PCI success, procedural complications, and meeting OPTIVUS criteria were not different between groups. The cumulative 1-year incidence of the primary endpoint was not different between single-session and staged multivessel PCI groups (9.0% vs 10.8%, log-rank P = 0.42). After adjusting confounders, the effect of single-session multivessel PCI relative to staged multivessel PCI was not significant for the primary endpoint (HR: 0.95; 95% CI: 0.58-1.55; P = 0.84). Conclusions: Single-session and staged multivessel IVUS-guided PCI had similar 1-year outcomes.

Ten-year clinical outcomes from a randomized trial comparing new-generation everolimus-eluting stent versus first-generation Sirolimus-eluting stent: Results from the RESET extended study.

BACKGROUND: New-generation drug-eluting stents (DES) achieved technological innovations and reported clinical advantages as compared with first-generation DES in clinical trials with 3-5 years follow-up. However, detailed clinical outcome data in very long-term follow-up is still scarce. OBJECTIVES: To evaluate 10-year clinical outcomes after first- and new-generation DES implantation. METHODS: In this extende follow-up study of the RESET, which is a largest randomized trial comparing everolimus-eluting stent (EES) with Sirolimus-eluting stent (SES), the study population consisted of 2892 patients from 84 centers. The primary efficacy and safety endpoints were target lesion revascularization (TLR) and a composite of death or myocardial infarction (MI), respectively. Complete 10-year follow-up was achieved in 87.9% of patients. RESULTS: Cumulative 10-year incidences of TLR and non-TLR were not significantly different between EES and SES (13.9% vs. 15.7%, Log-rank p = 0.20, and 33.4% vs. 31.3%, Log-rank p = 0.30). The cumulative 10-year incidence of death/MI was also not significantly different between the groups (32.5% vs. 34.4%, Log-rank p = 0.18). Cumulative 10-year incidence of definite stent thrombosis was numerically lower in EES than in SES (1.0% vs. 1.7%, Log-rank p = 0.16). The lower risk of EES relative to SES was significant for a composite endpoint of target lesion failure (TLF: 19.6% vs. 24.9%, Log-rank p = 0.001) and target vessel failure (TVF: 26.7% vs. 31.4%, Log-rank p = 0.006). CONCLUSION: During 10-year of follow-up, the risks for primary efficacy and safety endpoints were not significantly different between new-generation EES and first-generation SES, although EES compared with SES was associated with a lower risk for composite endpoints such as TLF and TVF.

Biodegradable or durable polymer drug-eluting stents in patients with coronary artery disease: ten-year outcomes of the randomised NEXT Trial.

BACKGROUND: There are no randomised trials reporting clinical outcomes of biodegradable polymer biolimus-eluting stents (BP-BES) and durable polymer everolimus-eluting stents (DP-EES) at 10 years. AIMS: We aimed to compare the 10-year clinical outcomes between BP-BES and DP-EES. METHODS: The randomised NOBORI Biolimus-Eluting Versus XIENCE/PROMUS Everolimus-eluting Stent Trial (NEXT) was originally designed to evaluate the non-inferiority of BP-BES relative to DP-EES with the primary efficacy endpoint of target lesion revascularisation (TLR) at 1 year and the primary safety endpoint of death or myocardial infarction (MI) at 3 years. In this extended follow-up study, clinical outcomes were compared from 1 year after stent implantation up to 10 years between patients with BP-BES and DP-EES. RESULTS: From May to October 2011, NEXT enrolled a total of 3,241 patients from 98 centres in Japan. The current study population consisted of 2,417 patients (1,204 patients with BP-BES and 1,213 with DP-EES) from 66 centres that agreed to participate in the extended study. Complete 10-year follow-up was achieved in 87.5% of patients. The cumulative 10-year incidence of death or MI was 34.0% in the BP-BES group and 33.1% in the DP-EES group (hazard ratio [HR] 1.04, 95% confidence interval [CI]: 0.90-1.20; p=0.58). TLR occurred in 15.9% of patients in the BP-BES group and in 14.1% of the DP-EES group (HR 1.12, 95% CI: 0.90-1.40; p=0.32). In a landmark analysis at 1 year, the cumulative incidences of death or MI and TLR were not significantly different between the 2 groups. CONCLUSIONS: The safety and efficacy outcomes for BP-BES were not significantly different from those for DP-EES at 1 year and up to 10 years after stent implantation.

Rationale and design of an investigator-initiated, multicenter, prospective, placebo-controlled, double-blind, randomized trial to evaluate the effects of finerenone on vascular stiffness and cardiorenal biomarkers in type 2 diabetes and chronic kidney disease (FIVE-STAR).

BACKGROUND: The overactivation of mineralocorticoid receptor (MR) plays a key pathological role in the progression of cardiovascular and renal diseases by promoting pro-inflammatory and pro-fibrotic signaling. Recently, it has been found that finerenone, a novel nonsteroidal selective MR antagonist, can robustly improve cardiorenal outcomes in patients with type 2 diabetes (T2D) and a wide spectrum of chronic kidney disease (CKD). However, the mechanisms underlying the cardiorenal benefits of finerenone are poorly understood. Further, whether the clinical benefits are mediated by an improvement in vascular stiffness is not confirmed. Therefore, the current study aims to evaluate the effects of finerenone on vascular stiffness as assessed using cardio ankle vascular index (CAVI) and relevant cardiorenal biomarkers in patients with T2D and CKD. METHODS: The Effects of Finerenone on Vascular Stiffness and Cardiorenal Biomarkers in Type 2 Diabetes and Chronic Kidney Disease (FIVE-STAR) is an ongoing, investigator-initiated, multicenter, prospective, placebo-controlled, double-blind, randomized clinical trial in Japan. Its target sample size is 100 subjects. Recruitment will be performed from September 2023 to July 2024. After obtaining informed consent, eligible participants with T2D and CKD (25 mL/min/1.73 m2 ≤ estimated glomerular filtration ratio [eGFR] < 90 mL/min/1.73 m2 and 30 mg/g Cr ≤ urinary albumin-to-creatinine ratio [UACR] < 3500 mg/g Cr) will be equally randomized to receive 24-week treatment with either finerenone (starting dose at 10 mg once daily in participants with a baseline eGFR < 60 mL/min/1.73 m2 or at 20 mg once daily in those with a baseline eGFR ≥ 60 mL/min/1.73 m2) or dose-matched placebo. The primary endpoint is the change from baseline in CAVI at 24 weeks. The secondary endpoints are changes from baseline in UACR at 12 and 24 weeks and relevant serum and urinary biomarkers at 24 weeks. As an exploratory endpoint, proteomic analysis using the Olink® Target 96 panels will be also performed. DISCUSSION: FIVE-STAR is the first trial evaluating the therapeutic impact of finerenone on vascular stiffness and relevant cardiorenal biomarkers in patients with T2D and CKD. This study will provide mechanistic insights on the clinical benefits of finerenone based on recent cardiovascular and renal outcome trials.
