RESUMEN
BACKGROUND: Clinical and anatomical characteristics are often considered key factors in deciding between percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) in patients with complex coronary artery disease (CAD) such as left-main CAD or 3-vessel disease. However, little is known about the interaction between self-reported preprocedural physical/mental health and clinical outcomes after revascularization. METHODS: This subgroup analysis of the SYNTAXES trial (SYNTAX Extended Survival), which is the extended follow-up of the randomized SYNTAX trial (Synergy Between PCI With Taxus and Cardiac Surgery) comparing PCI with CABG in patients with left-main CAD or 3-vessel disease, stratified patients by terciles of Physical (PCS) or Mental Component Summary (MCS) scores derived from the preprocedural 36-Item Short Form Health Survey, with higher PCS and MCS scores representing better physical and mental health, respectively. The primary end point was all-cause death at 10 years. RESULTS: A total of 1656 patients with preprocedural 36-Item Short Form Health Survey data were included in the present study. Both higher PCS and MCS were independently associated with lower 10-year mortality (10-point increase in PCS adjusted hazard ratio, 0.84 [95% CI, 0.73-0.97]; P=0.021; in MCS adjusted hazard ratio, 0.85 [95% CI, 0.76-0.95]; P=0.005). A significant survival benefit with CABG over PCI was observed in the highest PCS (>45.5) and MCS (>52.3) terciles with significant treatment-by-subgroup interactions (PCS Pinteraction=0.033, MCS Pinteraction=0.015). In patients with both high PCS (>45.5) and MCS (>52.3), 10-year mortality was significantly higher with PCI compared with CABG (30.5% versus 12.2%; hazard ratio, 2.87 [95% CI, 1.55-5.30]; P=0.001), whereas among those with low PCS (≤45.5) or low MCS (≤52.3), there were no significant differences in 10-year mortality between PCI and CABG, resulting in a significant treatment-by-subgroup interaction (Pinteraction=0.002). CONCLUSIONS: Among patients with left-main CAD or 3-vessel disease, patient-reported preprocedural physical and mental health status was strongly associated with long-term mortality and modified the relative treatment effects of PCI versus CABG. Patients with the best physical and mental health had better 10-year survival with CABG compared with PCI. Assessment of self-reported physical and mental health is important when selecting the optimal revascularization strategy. REGISTRATION: URL: https://www.

BACKGROUND: P2Y12 inhibitor monotherapy without aspirin immediately after percutaneous coronary intervention (PCI) has not been tested in East Asian patients, so in this study we aimed to assess the safety and feasibility of reduced dose (3.75 mg/day) prasugrel monotherapy in Japanese patients presenting with chronic coronary syndrome (CCS).MethodsâandâResults: ASET-JAPAN is a prospective, multicenter, single-arm pilot study that completed enrolment of 206 patients from 12 Japanese centers in September 2022. Patients with native de-novo coronary lesions and a SYNTAX score <23 were treated exclusively with biodegradable-polymer platinum-chromium everolimus-eluting stent(s). Patients were loaded with standard dual antiplatelet therapy (DAPT) and following successful PCI and optimal stent deployment, they received low-dose prasugrel (3.75 mg/day) monotherapy for 3 months. The primary ischemic endpoint was a composite of cardiac death, spontaneous target-vessel myocardial infarction, or definite stent thrombosis. The primary bleeding endpoint was Bleeding Academic Research Consortium (BARC) type 3 or 5. At 3-month follow-up, there were no primary bleeding or ischemic events, or any stent thrombosis. CONCLUSIONS: This pilot study showed the safety and feasibility of prasugrel monotherapy in selected low-risk Japanese patients with CCS. This "aspirin-free" strategy may be a safe alternative to traditional DAPT following PCI.

BACKGROUND: Several studies have suggested that proton pump inhibitors (PPIs) may reduce the antiplatelet effects of clopidogrel and/or aspirin, possibly leading to cardiovascular events. AIMS: We aimed to investigate the association between PPI and clinical outcomes in patients treated with ticagrelor monotherapy or conventional antiplatelet therapy after percutaneous coronary intervention (PCI). METHODS: This is a subanalysis of the randomized GLOBAL LEADERS trial, comparing the experimental antiplatelet arm (23-month ticagrelor monotherapy following 1-month dual antiplatelet therapy [DAPT]) with the reference arm (12-month aspirin monotherapy following 12-month DAPT) after PCI. Patient-oriented composite endpoints (POCEs: all-cause mortality, myocardial infarction, stroke, or repeat revascularization) and its components were assessed stratified by PPI use as a time-dependent covariate in patients with the experiment or reference antiplatelet arm. RESULTS: Among 15,839 patients, 2115 patients (13.5%) experienced POCE at 2 years. In the reference arm, the use of PPIs was independently associated with POCE (hazard ratio [HR]: 1.27; 95% confidence interval [CI]: 1.12-1.44) and its individual components, whereas it was not in the experimental arm (HR: 1.04; 95% CI: 0.92-1.19; pinteraction = 0.035). During the second-year follow-up, patients taking aspirin with PPIs had a significantly higher risk of POCE compared to those on aspirin without PPIs (HR: 1.57; 95% CI: 1.27-1.94), whereas the risk did not differ significantly irrespective of PPI in ticagrelor monotherapy group (HR: 1.03; 95% CI: 0.83-1.28; pinteraction = 0.008). CONCLUSIONS: In contrast to conventional antiplatelet strategy, there were no evidence suggesting the interaction between ticagrelor monotherapy and PPIs on increased cardiovascular events, which should be confirmed in further studies.

AIMS: The aim of this article was to compare rates of all-cause death at 10 years following coronary artery bypass grafting (CABG) or percutaneous coronary intervention (PCI) in patients with or without diabetes. METHODS AND RESULTS: The SYNTAXES study evaluated up to 10-year survival of 1800 patients with three-vessel disease (3VD) and/or left main coronary artery disease (LMCAD) randomized to receive either PCI or CABG in the SYNTAX trial. Ten-year all-cause death according to diabetic status and revascularization strategy was examined. In diabetics (n = 452), the risk of mortality was numerically higher with PCI compared with CABG at 5 years [19.6% vs. 13.3%, hazard ratio (HR): 1.53, 95% confidence interval (CI): 0.96, 2.43, P = 0.075], with the opposite seen between 5 and 10 years (PCI vs. CABG: 20.8% vs. 24.4%, HR: 0.82, 95% CI: 0.52, 1.27, P = 0.366). Irrespective of diabetic status, there was no significant difference in all-cause death at 10 years between patients receiving PCI or CABG, the absolute treatment difference was 1.9% in diabetics (PCI vs. CABG: 36.4% vs. 34.5%, difference: 1.9%, 95% CI: -7.6%, 11.1%, P = 0.551). Among insulin-treated patients (n = 182), all-cause death at 10 years was numerically higher with PCI (47.9% vs. 39.6%, difference: 8.2%, 95% CI: -6.5%, 22.5%, P = 0.227). CONCLUSIONS: The treatment effects of PCI vs. CABG on all-cause death at 10 years in patients with 3VD and/or LMCAD were similar irrespective of the presence of diabetes. There may, however, be a survival benefit with CABG in patients with insulin-treated diabetes. The association between revascularization strategy and very long-term ischaemic and safety outcomes for patients with diabetes needs further investigation in dedicated trials.

Angiography-derived physiological assessment of coronary lesions has emerged as an alternative to wire-based assessment aiming at less-invasiveness and shorter procedural time as well as cost effectiveness in physiology-guided decision making. However, current available image-derived physiology software have limitations including the requirement of multiple projections and are time consuming. METHODS/DESIGN: The ReVEAL iFR (Radiographic imaging Validation and EvALuation for Angio-iFR) trial is a multicenter, multicontinental, validation study which aims to validate the diagnostic accuracy of the Angio-iFR medical software device (Philips, San Diego, US) in patients undergoing angiography for Chronic Coronary Syndrome (CCS). The Angio-iFR will enable operators to predict both the iFR and FFR value within a few seconds from a single projection of cine angiography by using a lumped parameter fluid dynamics model. Approximately 440 patients with at least one de-novo 40% to 90% stenosis by visual angiographic assessment will be enrolled in the study. The primary endpoint is the sensitivity and specificity of the iFR and FFR for a given lesion compared to the corresponding invasive measures. The enrollment started in August 2019, and was completed in March 2021. SUMMARY: The Angio-iFR system has the potential of simplifying physiological evaluation of coronary stenosis compared with available systems, providing estimates of both FFR and iFR. The ReVEAL iFR study will investigate the predictive performance of the novel Angio-iFR software in CCS patients. Ultimately, based on its unique characteristics, the Angio-iFR system may contribute to improve adoption of functional coronary assessment and the workflow in the catheter laboratory.

BACKGROUND: The recent approval of transcatheter aortic valve replacement (TAVR) in patients with low operative risk has paved the way for the introduction of novel and potentially improved technologies. The safety and efficacy of these novel technologies should be investigated in randomized control trials against the contemporary TAVR devices. The objective of the LANDMARK trial is to compare the balloon-expandable Myval transcatheter heart valve (THV) series with contemporary THV (SAPIEN THV and Evolut THV series) series in patients with severe symptomatic native aortic stenosis. METHODS/DESIGN: The LANDMARK trial (ClinicalTrials.govNCT04275726, EudraCT number 2020-000,137-40) is a prospective, randomized, multinational, multicenter, open-label, and noninferiority trial of approximately 768 patients treated with TAVR via the transfemoral approach. Patients will be allocated in a 1:1 randomization to Myval THV series (nâ¯=â¯384) or to contemporary THV (nâ¯=â¯384) (either of SAPIEN THV or Evolut THV series). The primary combined safety and efficacy endpoint is a composite of all-cause mortality, all stroke (disabling and nondisabling), bleeding (life-threatening or disabling), acute kidney injury (stage 2 or 3), major vascular complications, prosthetic valve regurgitation (moderate or severe), and conduction system disturbances (requiring new permanent pacemaker implantation), according to the Valve Academic Research Consortium-2 criteria at 30-day follow-up. All patients will have follow-up to 10 years following TAVR. SUMMARY: The LANDMARK trial is the first randomized head-to-head trial comparing Myval THV series to commercially available THVs in patients indicated for TAVR. We review prior data on head-to-head comparisons of TAVR devices and describe the rationale and design of the LANDMARK trial.

OBJECTIVES: This study aimed to assess the predictive ability of the Global Registry of Acute Coronary Events (GRACE) risk score 2.0 in contemporary acute coronary syndrome (ACS) patients, and its relation to antiplatelet strategies. BACKGROUND: The predictive value of the GRACE risk score in the contemporary ACS cohort and the appropriate antiplatelet regimen according to the risk remain unclear. METHODS: This is a subgroup analysis of the all-comers, randomized GLOBAL LEADERS trial, comparing ticagrelor monotherapy versus conventional dual-antiplatelet therapy (DAPT) after percutaneous coronary intervention (PCI). The GRACE risk score 2.0 with 1-year mortality prediction was implemented. The randomized antiplatelet effect was assessed in predefined three GRACE risk-groups; low-risk (GRACE <109), moderate-risk (GRACE 109-140), and high-risk (GRACE >140). RESULTS: The GRACE risk score was available in 6,594 out of 7,487 ACS patients among whom 1,743, 2,823, and 2,028 patients were classified as low-risk, moderate-risk, and high-risk, respectively. At 1 year, all-cause mortality occurred in 120 patients (1.8%). The discrimination ability of the GRACE model was moderate (C-statistic = 0.742), whereas 1-year mortality risk was overestimated (mean predicted mortality rate: 3.9%; the Hosmer-Lemeshow chi-square: 21.47; p = 0.006). There were no significant interactions between the GRACE risk strata and effects of the ticagrelor monotherapy on ischemic or bleeding outcomes at 1 year compared to the reference strategy. CONCLUSION: The GRACE risk score 2.0 is valuable in discriminating high risk ACS patients, however, the recalibration of the score is recommended for better risk stratification. There is no significant differences in efficacy and safety of ticagrelor monotherapy across the three GRACE risk strata.

OBJECTIVES: We investigated the impact of total stent length (TSL) and average nominal stent diameter (ASD) on 10-year mortality after percutaneous coronary intervention (PCI) in the SYNTAXES trial. BACKGROUND: TSL and ASD in patients treated with PCI are associated with major adverse cardiovascular events. However, the treatment effect of PCI with extensive and/or small stenting as compared with coronary artery bypass grafting (CABG) for complex coronary artery disease has not been fully evaluated. METHODS: Impacts on mortality of extensive stenting defined as TSL >100 mm and small stenting as ASD <3 mm were analyzed in 893 PCI patients and were compared to 865 CABG patients. RESULTS: TSL as a continuous variable was significantly associated with 10-year mortality (adjusted hazard ratio [HR], 1.05 [1.01-1.09] per 10 mm increase). PCI patients with extensive stenting had a higher 10 year mortality than CABG patients (adjusted HR, 1.97 [1.41-2.74]) or not- extensive stenting PCI (adjusted HR, 1.94 [1.36-2.77]). Although ASD did not have a significant association with 10 year mortality (adjusted HR, 0.97 [0.85-1.11] per 0.25 mm increase), PCI with small stents was associated with a higher 10 year mortality, compared to CABG (adjusted HR, 1.66 [1.23-2.26]) and PCI performed with large stents (adjusted HR, 1.74 [1.19-2.53]). Patients treated with not-extensive and large stents had similar mortality rates (24.0 versus 23.8%) as those treated with CABG. CONCLUSIONS: Extensive and small stenting were associated with higher 10 year mortality, compared with CABG. When patients have to be treated with extensive or small stenting, revascularization with CABG should be preferred.

OBJECTIVES: To compare the predictive performances of the prewiring, postwiring MI-SYNTAX scores, prewiring, and postwiring Updated Logistic Clinical SYNTAX score (LCSS) for 2-year all-cause mortality post percutaneous coronary intervention (PCI) in ST-elevation myocardial infarction (STEMI) patients. BACKGROUND: In patients with STEMI and undergoing primary PCI, coronary stenosis(es) distal to the culprit lesion is often observed after the restoration of coronary flow. To address comprehensively the complex coronary anatomy in these patients, prewiring and postwiring MI-SYNTAX scores have been reported in the literature. Furthermore, to enable individualized risk estimation for long-term all-cause mortality, the Updated LCSS has been developed by combining the anatomical SYNTAX score and clinical factors. METHODS: In the randomized GLOBAL LEADERS trial, anatomical SYNTAX score analysis was performed by an independent angiographic corelab for the first 4,000 consecutive patients as a prespecified analysis; of these, 545 presented with STEMI. The efficacy of the mortality predictions of the four scores at 2 years were evaluated based on their discrimination and calibration abilities. RESULTS: Complete data was available in 512 patients (93.9%). When the patients were stratified into two groups based on the median of the scores, the prewiring and postwiring Updated LCSSs demonstrated that the high-score groups were associated with higher rates of 2-year all-cause mortality compared to the low-score groups (6.6 vs. 1.2%; log-rank p = .001 and 6.6 vs. 1.2%; log-rank p = .001, respectively). There were no statistically significant differences for predicting the mortality between the prewiring (area under the curve [AUC] 0.625), postwiring MI-SYNTAX score (AUC 0.614), prewiring (AUC 0.755), and postwiring Updated LCSS (AUC 0.757). In the integrated discrimination improvement (IDI), the prewiring MI-SYNTAX score had a better discrimination for the mortality than the postwiring MI-SYNTAX score (IDI -0.0082; p = .029). The four scores had acceptable calibration abilities for 2-year all-cause mortality. CONCLUSIONS: The prewiring Updated LCSS predicts long-term all-cause mortality with clearly useful discrimination and acceptable calibration. Since the postwiring MI-SYNTAX score does not improve mortality prediction, the prewiring MI-SYNTAX score may be preferred for the 2-year mortality prediction using the Updated LCSS.

BACKGROUND: Patients with both diabetes mellitus (DM) and chronic kidney disease (CKD) are a subpopulation characterized by ultrahigh ischemic and bleeding risk after percutaneous coronary intervention. There are limited data on the impact of ticagrelor monotherapy among these patients. METHODS: In this post hoc analysis of the GLOBAL-LEADERS trial, the treatment effects of the experimental (one-month dual-antiplatelet therapy [DAPT] followed by 23-month ticagrelor monotherapy) versus the reference regimen (12-month DAPT followed by 12-month aspirin alone) were analyzed according to DM/CKD status. The primary endpoint was a composite endpoint of all-cause death or new Q-wave myocardial infarction at 2-years. The patient-oriented composite endpoint (POCE) was defined as the composite of all-cause death, any stroke, site-reported MI and any revascularization, whereas net adverse clinical events (NACE) combined POCE with BARC type 3 or 5 bleeding events. RESULTS: At 2 years, the DM + /CKD + patients had significantly higher incidences of the primary endpoint (9.5% versus 3.1%, adjusted HR 2.16; 95% CI [1.66-2.80], p < 0.001), BARC type 3 or 5 bleeding events, stroke, site-reported myocardial infraction, all revascularization, POCE, and NACE, compared with the DM-/CKD- patients. Among the DM + /CKD + patients, after adjustment, there were no significant differences in the primary endpoints between the experimental and reference regimen; however, the experimental regimen was associated with lower rates of POCE (20.6% versus 25.9%, HR 0.74; 95% CI [0.55-0.99], p = 0.043, pinteraction = 0.155) and NACE (22.7% versus 28.3%, HR 0.75; 95% CI [0.56-0.99], p = 0.044, pinteraction = 0.310), which was mainly driven by a lower rate of all revascularization, as compared with the reference regimen. The landmark analysis showed that while the experimental and reference regimen had similar rates of all the clinical endpoints during the first year, the experimental regimen was associated with significantly lower rates of POCE (5.8% versus 11.0%, HR 0.49; 95% CI [0.29-0.82], p = 0.007, pinteraction = 0.040) and NACE (5.8% versus 11.2%, HR 0.48; 95% CI [0.29-0.82], p = 0.007, pinteraction = 0.013) in the second year. CONCLUSION: Among patients with both DM and CKD, ticagrelor monotherapy was not associated with lower rates of all-cause death or new Q-wave, or major bleeding complications; however, it was associated with lower rates of POCE and NACE. These findings should be interpreted as hypothesis-generating. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov (NCT01813435).

OBJECTIVES: We aimed to investigate the prognostic utility of the anatomical CABG SYNTAX and logistic clinical SYNTAX scores for mortality after percutaneous coronary intervention (PCI) in patients with prior coronary artery bypass grafts (CABG). BACKGROUND: The anatomical SYNTAX score evaluated the anatomical complexity of coronary artery disease and helped predict the prognosis of patients undergoing PCI. The anatomical CABG SYNTAX score was derived from the anatomical SYNTAX score in patients with prior CABG, whilst the logistic clinical SYNTAX score was developed by incorporating clinical factors into the anatomical SYNTAX score. METHODS: We calculated the anatomical CABG SYNTAX score and logistic clinical SYNTAX score in 205 patients in the GLOBAL LEADERS trial. The predictive abilities of these scores for 2-year all-cause mortality were evaluated. RESULTS: Using the median scores as categorical thresholds between low and high score groups, the logistic clinical SYNTAX score was able to discriminate the risk of 2-year mortality, unlike the anatomical CABG SYNTAX score. The logistic clinical SYNTAX was significantly better at predicting 2-year mortality, compared to the anatomical CABG SYNTAX score, as evidenced by AUC values in receiver-operating characteristic curve analysis (0.806 vs. 0.582, p < .001) and integrated discrimination improvement (0.121, p < .001). CONCLUSIONS: The logistic clinical SYNTAX score was superior to the anatomical CABG SYNTAX score in predicting 2-year mortality.

Conventional diuretic therapy for low-flow (LF) severe aortic stenosis (SAS) often has an inadequate effect or causes hemodynamic instability. Tolvaptan is used for acute heart failure in addition to conventional diuretics, and it does not cause intravascular dehydration. This study aimed to retrospectively investigate the safety and efficacy of tolvaptan in the acute phase in 56 consecutive patients with SAS and compared LF-SAS with normal-flow (NF) SAS. The primary endpoints were adverse clinical events (death, worsening heart failure, worsening renal failure, fatal arrhythmia, cardiogenic or hypovolemic shock, and use of inotropic agents) and the volume of urine within 48 h of tolvaptan administration. Among 56 patients, 16 had LF-SAS (29%), and 40 had NF-SAS (71%). Severe adverse clinical events were not observed 48 h after tolvaptan administration. In both groups, the urine volume significantly increased after tolvaptan administration in comparison to 24 h before tolvaptan administration (both, p < 0.01). There were no changes in the urine volume during the initial 24 and 48 h. In the LF-SAS group, tolvaptan resulted in a significant decrease in fluid balance during the initial 24 and 48 h compared to 24 h before tolvaptan administration (p < 0.05). Adding tolvaptan to conventional treatment is safe and effective without renal dysfunction and hypotension in patients with SAS, including those with LF.

Pre-procedural valvuloarterial impedance (Zva) is considered as a useful predictor of mortality in patients diagnosed as having severe aortic stenosis (AS) who undergo transcatheter aortic valve implantation (TAVI). However, the prognostic significance of post-procedural Zva remains unclear. We aimed to evaluate the prognostic significance of Zva after TAVI. We retrospectively analyzed the clinical and echocardiographic data of 1004 consecutive elderly patients (median 84 years old, 27.5% men) who underwent TAVI for severe symptomatic AS. Zva was calculated after TAVI, and patients were divided into three groups based on tertile values: the high [> 3.33 (n = 335)], intermediate [2.49-3.33 (n = 334)], and low Zva groups [< 2.49 (n = 335)]. The estimated 2-year all-cause and cardiovascular mortalities using Kaplan-Meier analysis were 16.2% [95% confidence interval (CI) 11.8-20.4] and 5.9% (95% CI 3.2-8.6), respectively. There were no significant intergroup differences in each endpoint (long-rank p = 0.518 for all-cause mortality, p = 0.757 for cardiovascular mortality). Multivariable Cox regression analyzes with adjustments of patient characteristics and medications showed that the post-procedural Zva was not associated with the 2-year all-cause mortality [intermediate Zva group versus (vs.) low Zva group: adjusted hazard ratio (aHR) = 1.34, 95% CI 0.75-2.40, p = 0.316; high Zva group vs. low Zva group: aHR = 1.17, 95% CI 0.64-2.16, p = 0.613] and cardiovascular mortality (intermediate Zva group vs. low Zva group: aHR = 1.50, 95% CI 0.56-4.06, p = 0.421; high Zva group vs. low Zva group: aHR = 1.25, 95% CI 0.43-3.65, p = 0.682). Our results suggest that post-procedural Zva was not associated with 2-year all-cause or cardiovascular mortalities in patients with severe symptomatic AS who underwent TAVI.

This study is aimed to evaluate the performance of MAGGIC risk score for predicting mortality by external validation using multicenter transcatheter aortic valve replacement (TAVR) registry. We assessed 1383 patients who underwent TAVR from October 2013 to April 2016. Patients were divided into 2 groups according to the median of MAGGIC score and we compared the incidence of all-cause death between high and low MAGGIC score. To assess whether the MAGGIC risk score add prognostic value on STS risk score, we also compared the incidence of all-cause death between the 2 groups according to low, intermediate, and high STS score. The median of MAGGIC score was 29 (interquartile range: 13-46). Within 2 years, 147 cases of all-cause death were observed. The high MAGGIC (30-46) risk score was significantly associated with an increased risk of all-cause death as compared to low MAGGIC (11-29) risk score and this relationship was also observed in patients with high STS risk score. However, this relationship was not observed in patients with low and intermediate STS score. Multivariate analysis showed that the MAGGIC risk score was an independent predictor of all-cause death (hazard ratio, 1.07; 95% confidence interval, 1.03-1.11). Our results demonstrated that the MAGGIC score predicts all-cause death in TAVR population and provides better risk stratification, particularly in patients with high STS risk.

Prior research has revealed poorer clinical outcomes after drug-eluting stent (DES) implantation for hemodialysis patients. This study aims to investigate the long-term clinical and angiographic outcomes after new-generation DES implantation for hemodialysis patients.We retrospectively enrolled 91 consecutive patients (118 lesions) who underwent successful new-generation DES (everolimus-, zotarolimus-, and biolimus-eluting stents) implantation for the first time. We measured the serum calcium and phosphorus levels in the blood samples obtained just before hemodialysis. The follow-up period of clinical events was, at least, 1.5 years. In this study, major adverse cardiac and cerebrovascular events (MACCE) and clinically driven target lesion revascularization were reported in 36 (39.6%) and 11 (12.1%) patients, respectively. The prevalence of peripheral artery disease was significantly higher in the MACCE group (41.7% versus 14.5%, P = 0.006). The serum calcium level was significantly higher in the MACCE group (9.34 ± 0.92 mg/dL versus 8.77 ± 0.88 mg/dL; P = 0.004). The multivariate Cox proportional hazards model revealed that the serum calcium level (hazard ratio, 1.86; 95% confidence interval [CI]: 1.26-2.77; P = 0.002), suboptimal (over 55 mg2/dL2) calcium-phosphorus product (hazard ratio, 3.27; 95% CI: 1.41-7.61; P = 0.006) and the coexistence of peripheral artery disease (hazard ratio, 3.15; 95% CI: 1.49-6.65; P = 0.003) were independent predictors of MACCE.For hemodialysis patients, MACCE remains a frequent occurrence after new-generation DES implantation and is associated with calcium-phosphate metabolism and peripheral artery disease.

BACKGROUND: Rotational atherectomy (RA) is an adjunct tool for the management of heavily calcified coronary lesions during percutaneous coronary intervention (PCI), but the long-term clinical outcomes of RA use remain unclear in this drug-eluting stent era.MethodsâandâResults:This multi-center registry assessed the characteristics and outcomes of patients treated by RA for calcified coronary lesions between 2004 and 2015. Among 1,090 registered patients, mean age was 70±10 years and 815 (75%) were male. Sixty percent of patients had diabetes mellitus and 27.7% were receiving hemodialysis. The procedure was successful in 96.2%. In-hospital death occurred in 33 patients (3.0%), and 14 patients (1.3%) developed definite/probable stent thrombosis. During the median follow-up period of 3.8 years, the incidence of major adverse cardiac events (MACE), defined as all-cause death, acute coronary syndrome, stent thrombosis, target vessel revascularization and stroke, was 46.7%. On multivariable Cox hazard analysis, hemodialysis (HR, 2.08; 95% CI: 1.53-2.86; P<0.0001) and age (HR, 1.03; 95% CI: 1.01-1.04; P<0.0001) were strong independent predictors of MACE. Conversely, statin treatment was associated with lower incidence of MACE (P=0.035). CONCLUSIONS: This study has provided the largest Japanese dataset for long-term follow-up of RA. Although RA in calcified lesions appears feasible with a high rate of procedural success, a high incidence of MACE was observed.

Thin-high signals (THS), detectable by optical coherence tomography (OCT), represent the paclitaxel coverage of in-stent restenotic tissue. This study was conducted to assess the relationship between THS and angiographic outcomes by means of quantified post-procedural frequency-domain OCT (FD-OCT) analysis. From January 2014 to July 2016, 41 patients underwent FD-OCT-guided percutaneous coronary intervention using paclitaxel-coated balloon (PCB) to prevent in-stent restenosis. Of these, we retrospectively enrolled 32 patients (38 lesions) who underwent a 6- to 9-month follow-up angiogram. THS were assessed quantitatively, as THS length and lumen perimeter length were measured using semi-automated software; %THS was calculated by the following formula; total THS area/lumen perimeter area × 100. THS were detected in all 38 lesions that had undergone PCB angioplasty. THS and %THS were significantly higher in lesions without binary restenosis (3.34 ± 2.11 vs. 11.48 ± 8.53 mm2, p = 0.001 and 1.49 ± 0.73 vs. 4.42 ± 2.71%, p = 0.001, respectively). Values for THS, which indicates the paclitaxel coverage on restenotic tissue, are associated with reducing restenosis after PCB for in-stent restenosis.

The midterm safety and feasibility of transcatheter aortic valve implantation (TAVI) for patients with a history of coronary artery bypass graft (CABG) and high operative risk are unclear. This study compared the midterm outcomes of patients undergoing TAVI with or without previous CABG surgery. Between October 2013 and July 2016, 1,613 patients underwent TAVI according to the Optimized CathEter vAlvular iNtervention (OCEAN)-TAVI registry (previous CABG: n = 120; no previous CABG: n = 1493). The propensity score comprised the variables of the Society of Thoracic Surgeons Score, previous myocardial infarction, peripheral artery disease, chronic kidney disease > stage 2 (estimated glomerular filtration rate < 60 mL/min/1.73 m2), and the TAVI approach method. After propensity matching, 118 patients were classified into the CABG and non-CABG groups. Kaplan-Meier analysis revealed that the incidence of overall cardiovascular death in the CABG group was significantly higher than in the non-CABG group (log-rank; p = 0.004). Overall mortality due to heart failure was higher in the CABG than in the non-CABG group (8.5 vs. 1.7%, p = 0.038). The present study demonstrated that patients with a history of CABG who underwent TAVI had a higher frequency of cardiovascular death, mainly due to heart failure. Heart failure detection and rigorous heart failure management are required after TAVI.

Our aim was to assess the clinical effects of myocardial injury after transcatheter aortic-valve implantation (TAVI). Between October 2013 and July 2016, 157 patients underwent TAVI with Sapien XT, Sapien 3, or CoreValve prostheses at our institute. Of these, 130 patients for whom the transapical approach was not used were included in this study. Myocardial injury was defined as a peak troponin I level of ≥1.5 ng/mL within 48 hours after TAVI. We evaluated the predictors of myocardial injury and compared the clinical outcomes of 82 patients classified as the myocardial injury group and 44 patients classified as the non-myocardial injury group. The patients were aged 85 ± 6 years. Myocardial injury occurred in 82 patients (65.1%). Age (per 1 increase) (odds ratio [OR]: 1.11, 95% confidence interval [CI]: 1.01-1.22, P = 0.041), female sex (OR: 3.88, 95% CI: 1.23-12.22, P = 0.021), valve type (Sapien XT; OR: 4.22, 95% CI: 1.15-15.47, P = 0.03, Core valve; OR: 18.12, 95% CI: 2.86-114.59, P = 0.002), balloon aortic valvuloplasty as a bridge therapy (OR: 0.10, 95% CI: 0.02-0.42, P = 0.002), and left ventricular end-diastolic volume (LVEDV) (per 1 increase) (OR: 0.97, 95% CI: 0.95-0.99, P = 0.003) were associated with myocardial injury in a multivariate model. The myocardial injury group did not have a higher rate of midterm (365-day) mortality (log-rank test P = 0.57) than the non-myocardial injury group on Kaplan-Meier analysis. Myocardial injury after TAVI was not associated with midterm mortality.

Coronary optical coherence tomography (OCT) has the potential to identify in-stent neoatherosclerosis, which is a possible risk factor for late acute coronary events after drug-eluting stent implantation. The purpose of this study was to investigate differences between mid-term and late in-stent restenosis after stent implantation by quantitative and semiautomated tissue property analysis using OCT. In total, 1063 OCT image frames of 16 lesions in 15 patients were analyzed. This included 346 frames of 6 lesions in late in-stent restenosis, which was defined as restenosis that was not detected at 6 to 12 months but ≥ 12 months after follow-up coronary angiography. Signal attenuation was circumferentially analyzed using a dedicated semiautomated software. Attenuation was assessed along 200 lines delineated radially for analysis of the in-stent restenotic lesions (between the lumen and stent contours). All lines were anchored by the image wire to avoid artifacts resulting from wire location. Stronger signal attenuation at the frame level (2.46 ± 0.78 versus 1.47 ± 0.32, P < 0.001) and higher maximum signal intensity at the lesion level (9.19 ± 0.19 versus 8.84 ± 0.32, P = 0.018) were observed in late in-stent restenotic lesions than in mid-term in-stent restenotic lesions. OCT demonstrated stronger signal attenuation and higher maximum signal intensity in late in-stent restenotic lesions than in mid-term in-stent restenotic lesions, indicating the possibility of neoatherosclerosis.
