A 78-year-old woman with hypertension was admitted to our hospital with palpitation and chest discomfort. She had been nervous since she learned about a severe earthquake on the news. An electrocardiogram showed ST-segment elevation in leads I, aVL, and V2-6. Emergency coronary angiography demonstrated no significant coronary stenosis and left ventriculography revealed marked akinesis of apical left ventricle with hyperkinesis of the basal segments, indicating typical takotsubo cardiomyopathy. On day 24, an electrocardiogram showed diffuse T-wave inversion, but ST-segment elevation remained in V3-6. Cardiac magnetic resonance imaging revealed left ventricular apical aneurysm and epicardial late gadolinium enhancement in the apex, indicating takotsubo-inflicted myocardial injury. Although many previous reports show takotsubo cardiomyopathy is a reversible left ventricular systolic dysfunction with less significant complications, it should be reconsidered as benign disease with long-term complications. Learning objective: Although many previous reports show takotsubo cardiomyopathy (TC) is a reversible left ventricular (LV) systolic dysfunction with less significant complications, our patient is a rare case of TC which led to LV apical aneurysm. It was believed that lack of late gadolinium enhancement (LGE) was necessary to diagnose TC, however we detected epicardial LGE in the LV apical wall and this finding might indicate nonreversible change in this case.
RESUMEN
Introduction: The long-term impact of renin-angiotensin system (RAS) inhibitors for secondary prevention in patients with chronic kidney disease (CKD) and coexisting coronary artery disease remains unclear. Methods: Altogether, 1,160 consecutive patients with CKD (mean age, 70 ± 9 years; 78% men) who underwent their first percutaneous coronary intervention (PCI) between 2000 and 2018 were included and analyzed. Based on their RAS inhibitor use, 674 patients (58%) were allocated to the RAS inhibitor group, and 486 patients (42%) were allocated to the non-RAS inhibitor group. This study evaluated the incidence of 3-point major adverse cardiovascular events (3P-MACE), including cardiovascular death, nonfatal acute coronary syndrome and nonfatal stroke, admission for heart failure (HF), target vessel revascularization (TVR), and all-cause death. Results: During a median follow-up duration of 7.8 years, 280 patients (24.1%) developed 3P-MACE, 134 patients (11.6%) were hospitalized for HF, 171 patients (14.7%) underwent TVR, and 348 patients (30.0%) died of any causes. The cumulative incidence rate of 3P-MACE in the RAS inhibitor group was significantly lower than in the non-RAS inhibitor group (31.7% vs. 39.0%, log-rank test, p = 0.034); however, that of admission for HF in the RAS inhibitor group was significantly higher than in the non-RAS inhibitor group (28.1% vs. 13.3%, log-rank test, p < 0.001). The subgroup of preserved ejection fraction, non-acute myocardial infarction, and non-proteinuria tended to promote the onset of HF rather than cardiovascular prevention by RAS inhibitors. Conclusion: The long-term RAS inhibitor use for patients with CKD after PCI might prevent cardiovascular events but increase the risk of HF.
RESUMEN
BACKGROUND: Primary percutaneous coronary intervention (PCI) for ST-segment-elevation myocardial infarction (STEMI) complicated by cardiogenic shock (CS) may reduce the risk of subsequent cardiovascular events but remains challenging. The study aim was to evaluate the clinical characteristics and long-term outcomes of patients undergoing primary PCI for STEMI with CS. METHODS: We conducted an observational cohort study of patients with STEMI who underwent primary PCI between April 2004 and December 2017 at Juntendo University Shizuoka Hospital. The primary outcome was cardiovascular death (CVD) during the median 3-year follow-up. We performed a landmark analysis for the incidence of CVD from 0â¯day to 1â¯year and from 1 to 10â¯years. RESULTS: Among the 1758 STEMI patients in the cohort, 212 (12.1â¯%) patients with CS showed significantly higher 30-day CVD rate on admission than those without (26.4â¯% vs 2.9â¯%). Landmark Kaplan-Meier analysis showed that CVD from day 0 to year 1 was significantly higher in the patients with CS (log-rank pâ¯<â¯0.0001). Multivariate Cox regression analysis showed that CS was significantly associated with higher cardiovascular mortality (adjusted hazard ratio, 11.8; 95%confidence intervals, 7.78-18.1; pâ¯<â¯0.0001), but the mortality rates from 1 to 10â¯years were comparable (log-rank pâ¯=â¯0.68). CONCLUSION: The cardiovascular 1-year mortality rate for patients with STEMI was higher for those with CS on admission than without, but the mortality rates of >1â¯year were comparable. Surviving the early phase is essential for patients with STEMI and CS to improve long-term outcomes.

PURPOSE: Asians often face the problems of clopidogrel resistance and East Asian paradox. This study aimed to evaluate the effects of P2Y12 inhibitors, including low-dose prasugrel 2.5 mg, on the P2Y12 reaction unit (PRU) in the chronic phase after percutaneous coronary intervention (PCI). METHODS: A total of 348 patients were studied. PRU was measured 6-12 months after PCI and subsequently, 6 months later using a P2Y12 assay, respectively. This study evaluated the proportion of bleeding risk (PRU ≤ 85) and ischemic risk (PRU ≥ 239) as primary endpoints, and the prediction of bleeding risk and ischemic risk using multivariable logistic regression analysis. RESULTS: At baseline, 136 patients (39%) received prasugrel 3.75 mg, 48 patients (14%) received prasugrel 2.5 mg, and 164 patients (47%) received clopidogrel 75 mg. Clopidogrel 75 mg had a significantly higher proportion of ischemic risk within one year after PCI than the other groups, and was an independent predictor for ischemic risk with reference of prasugrel 3.75 mg. In addition, switching from clopidogrel 75 mg to prasugrel 2.5 mg significantly lowered and aggregated the PRU value. Whereas, dose reduction of prasugrel had a significantly lower proportion of bleeding risk over one year after PCI than the continuation of prasugrel 3.75 mg, and was an independent predictor for bleeding risk with reference of continuation of prasugrel 3.75 mg. CONCLUSIONS: Prasugrel 2.5 mg has a lower ischemic risk and a more stable PRU value compared with clopidogrel treatment. Prasugrel also contributes to a decline in bleeding risk with concomitant dose reduction.

RESUMEN
BACKGROUND: Recent clinical trials have shown that percutaneous coronary intervention (PCI) for non-culprit lesions (NCLs) reduces the risk of adverse events in patients with ST-segment elevation myocardial infarction (STEMI), but the effect on long-term outcomes remains unclear in acute coronary syndrome (ACS) patients and a real-world clinical setting. METHODS: A retrospective observational cohort study of ACS patients who underwent primary PCI between April 2004 and December 2017 at Juntendo University Shizuoka Hospital, Japan, was performed. The primary endpoint was the composite of cardiovascular disease death (CVD death) and non-fatal myocardial infarction (MI) during the mean follow-up period of 2.7 years, and a landmark analysis for the incidence of the primary endpoint from 31 days to 5 years between the multivessel PCI group and the culprit only PCI group was performed. Multivessel PCI was defined as PCI including non-infarct-related coronary arteries within 30 days after the onset of ACS. RESULTS: Of the 1109 ACS patients with multivessel coronary artery disease of the current cohort, multivessel PCI was performed in 364 (33.2 %) patients. The incidence of the primary endpoint from 31 days to 5 years was significantly lower in the multivessel PCI group (4.0 % vs. 9.6 %, log-rank p = 0.0008). Multivariate Cox regression analysis showed that multivessel PCI was significantly associated with fewer cardiovascular events (HR 0.37, 95 % CI 0.19-0.67, p = 0.0008). CONCLUSION: In ACS patients with multivessel coronary artery disease, multivessel PCI may reduce the risk of CVD death and non-fatal MI compared to culprit-lesion-only PCI.

BACKGROUND: This study aimed to compare the coronary plaque characterization by cardiovascular magnetic resonance (CMR) and near-infrared spectroscopy (NIRS)-intravascular ultrasound (IVUS) (NIRS-IVUS), and to determine whether pre-percutaneous coronary intervention (PCI) evaluation using CMR identifies high-intensity plaques (HIPs) at risk of peri-procedural myocardial infarction (pMI). Although there is little evidence in comparison with NIRS-IVUS findings, which have recently been shown to identify vulnerable plaques, we inferred that CMR-derived HIPs would be associated with vulnerable plaque features identified on NIRS-IVUS. METHODS: 52 patients with stable coronary artery disease who underwent CMR with non-contrast T1-weighted imaging and PCI using NIRS-IVUS were studied. HIP was defined as a signal intensity of the coronary plaque-to-myocardial signal intensity ratio (PMR) ≥ 1.4, which was measured from the data of CMR images. We evaluated whether HIPs were associated with the NIRS-derived maximum 4-mm lipid-core burden index (maxLCBI4mm) and plaque morphology on IVUS, and assessed the incidence and predictor of pMI defined by the current Universal Definition using high-sensitive cardiac troponin-T. RESULTS: Of 62 lesions, HIPs were observed in 30 lesions (48%). The HIP group had a significantly higher remodeling index, plaque burden, and proportion of echo-lucent plaque and maxLCBI4mm ≥ 400 (known as large lipid-rich plaque [LRP]) than the non-HIP group. The correlation between the maxLCBI4mm and PMR was significantly positive (r = 0.51). In multivariable logistic regression analysis for prediction of HIP, NIRS-derived large LRP (odds ratio [OR] = 5.41; 95% confidence intervals [CIs] 1.65-17.8, p = 0.005) and IVUS-derived echo-lucent plaque (OR = 5.12; 95% CIs 1.11-23.6, p = 0.036) were strong independent predictors. Furthermore, pMI occurred in 14 of 30 lesions (47%) with HIP, compared to only 5 of 32 lesions (16%) without HIP (p = 0.005). In multivariable logistic regression analysis for prediction of incidence of pMI, CMR-derived HIP (OR = 5.68; 95% CIs 1.53-21.1, p = 0.009) was a strong independent predictor, but not NIRS-derived large LRP and IVUS-derived echo-lucent plaque. CONCLUSIONS: There is an important relationship between CMR-derived HIP and NIRS-derived large LRP. We also confirmed that non-contrast T1-weighted CMR imaging is useful for characterization of vulnerable plaque features as well as for pre-PCI risk stratification. Trial registration The ethics committee of Juntendo Clinical Research and Trial Center approved this study on January 26, 2021 (Reference Number 20-313).

Background: Sarcopenia, which is evaluated based on appendicular skeletal muscle mass (ASM) using dual-energy X-ray absorptiometry and bioelectrical impedance analysis, is a prognostic predictor for adverse outcomes in patients with coronary artery disease (CAD). However, a simple equation for estimating ASM is yet to be validated in clinical practice. Methods: We enrolled 2211 patients with CAD who underwent percutaneous coronary intervention at our hospital between 2010 and 2017. The mean age was 68 years and 81.5 % were men. Patients were divided into 2 groups based on each ASM index (ASMI): low; male < 7.3 and female < 5.0 and high; male ≥ 7.3 and female ≥ 5.0. ASM was calculated using the following equation: 0.193 × bodyweight + 0.107 × height - 4.157 × gender - 0.037 × age - 2.631. Primary endpoints were major adverse cardiac events (MACE, which includes cardiovascular death, non-fatal myocardial infarction, non-fatal stroke, and hospitalization for heart failure), and all-cause mortality. Results: During the median follow-up period of 4.8 years, cumulative incidence of events were significantly higher in the low ASMI group. Cox proportional hazards model revealed that the low ASMI group had a significantly higher risk of primary endpoints than the high ASMI group (all-cause mortality; hazard ratio (HR): 2.13, 95 % confidence interval [CI]: 1.40-3.22, p < 0.001 and 4-point MACE; HR: 1.72, 95 % CI: 1.12-2.62, p = 0.01). Similar trends were observed after stratification by age of 65 years. Conclusion: Low ASMI, evaluated using the aforementioned equation, is an independent predictor of MACE and all-cause mortality in patients with CAD.
RESUMEN
AIM: Apolipoprotein E (ApoE) strongly affects arteriosclerosis but has atheroprotective effects in combination with high-density lipoprotein cholesterol (HDL-C). The impact of the quantitative relationship between serum ApoE and HDL-C levels in patients with coronary artery disease (CAD) remains unclear. METHODS: A total of 3632 consecutive patients who underwent their first intervention between 2000 and 2016 were included. They were categorized into normal and abnormal HDL-C groups based on the normal HDL-C value, and each group was subdivided into high and low ApoE subgroups based on the group-specific median ApoE value. We evaluated the incidence of major adverse cardiac and cerebrovascular events (MACCE), including cardiovascular death, non-fatal myocardial infarction, non-fatal stroke, and all-cause deathResults: During a 6.4-year follow-up, 419 patients developed MACCE and 570 patients died. The interaction term between ApoE levels and HDL-C status in MACCE and all-cause death proved to be statistically significant. Kaplan-Meier analysis revealed that the cumulative incidence of MACCE was significantly higher for elevated pre-procedural ApoE levels than for reduced preprocedural ApoE levels in the normal HDL-C group. Conversely, the cumulative incidence of MACCE was significantly higher for reduced pre-procedural ApoE levels than for elevated pre-procedural ApoE levels in the abnormal HDL-C group. After adjustment for important covariates, multivariable Cox hazard analysis revealed that the serum ApoE level was a strongly independent predictor of MACCE; this was inversely related in both groups. CONCLUSIONS: Serum ApoE levels may have a paradoxical impact on the future cardiovascular risk depending on the HDL-C status in patients with CAD.

Background In-stent restenosis, especially for neoatherosclerosis, is a major concern following percutaneous coronary intervention. This study aimed to elucidate the association of features of in-stent restenosis lesions revealed by optical coherence tomography (OCT)/optical frequency domain imaging (OFDI) and the extent of lipid-rich neointima (LRN) assessed by near-infrared spectroscopy (NIRS) and intravascular ultrasound, especially for neoatherosclerosis. Methods and Results We analyzed patients undergoing percutaneous coronary intervention for in-stent restenosis lesions using both OCT/OFDI and NIRS-intravascular ultrasound. OCT/OFDI-derived neoatherosclerosis was defined as lipid neointima. The existence of large LRN (defined as a long segment with 4-mm maximum lipid core burden index ≥400) was evaluated by NIRS. In 59 patients with 64 lesions, neoatherosclerosis and large LRN were observed in 17 (26.6%) and 21 lesions (32.8%), respectively. Naturally, large LRN showed higher 4-mm maximum lipid core burden index (median [interquartile range], 623 [518-805] versus 176 [0-524]; P<0.001). In OCT/OFDI findings, large LRN displayed lower minimal lumen area (0.9±0.4 versus 1.3±0.6 mm2; P=0.02) and greater max lipid arc (median [interquartile range], 272° [220°-360°] versus 193° [132°-247°]; P=0.004). In the receiver operating characteristic curve analysis, 4-mm maximum lipid core burden index was the best predictor for neoatherosclerosis, with a cutoff value of 405 (area under curve, 0.92 [95% CI, 0.83-1.00]). In multivariable logistic analysis, only low-density lipoprotein cholesterol (odds ratio, 1.52 [95% CI, 1.11-2.08]) was an independent predictor for large LRNs. Conclusions NIRS-derived large LRN was significantly associated with neoatherosclerosis by OCT/OFDI. The neointimal characterization by NIRS-intravascular ultrasound has potential as an alternative method of OCT/OFDI for in-stent restenosis lesions.

BACKGROUND AND AIMS: The relationship of apolipoprotein A-I (ApoA-I) and renal function in patients after intervention remain unclear, thus, we aimed to evaluate the combined impacts of ApoA-I and kidney disease (KD). MATERIAL AND METHODS: Altogether, 4101 consecutive patients who underwent intervention between 2000 and 2016 were included. The patients were divided into four groups based on the median ApoA-I values and presence of KD. We evaluated the incidence of major adverse cardiac and cerebrovascular events (MACCE), including cardiovascular death, non-fatal acute coronary syndrome and non-fatal stroke, and all-cause death. RESULTS: During the median follow-up period of 6.2â¯years, 618 patients (15.1%) developed MACCE, and 627 patients (15.3%) died. ApoA-I level was significantly related to estimated glomerular filtration rate, and ApoA-I levels and KD status interaction term was statistically significant. Kaplan-Meier analysis revealed that the low ApoA-I with KD had the significantly highest cumulative incidence rate of MACCE and all-cause death compared to the other three groups. Additionally, ApoA-I levels and KD status were independent predictors of MACCE and all-cause death in multivariable Cox hazard analysis. CONCLUSION: The combined impacts of ApoA-I and renal function could be useful for evaluating cardiovascular and life prognoses in patients undergoing intervention.

BACKGROUND: Although short-term mortality of acute myocardial infarction (AMI) has decreased dramatically in the past few decades, sudden cardiac arrest remains a serious complication. The aim of the study was to assess the clinical characteristics and predictors of prognosis in AMI patients who experienced out-of-hospital cardiac arrest (OHCA). METHODS: We retrospectively registered consecutive AMI patients who were treated with emergency percutaneous coronary intervention (PCI) between 2004 and 2017. Clinical characteristics and outcomes were compared between patients with OHCA and those without OHCA. RESULTS: Among 2101 AMI patients, 95 (4.7%) presented with OHCA. Younger age (odds ratio [OR]: 0.95; 95% confidence interval [CI]: 0.93-0.97; p < 0.0001), absence of diabetes mellitus (OR, 0.51; 95% CI, 0.30-0.85; p = 0.01) or dyslipidemia (OR, 0.56; 95% CI, 0.36-0.88; p = 0.01), left main trunk (LMT) or left anterior descending artery (LAD) as the culprit lesion (OR, 3.26; 95% CI, 1.99-5.33; p < 0.0001), and renal deficiency (OR, 3.64; 95% CI, 2.27-5.84; p < 0.0001) were significantly associated with incidence of OHCA. Thirty-day mortality was 32.6% in patients with OHCA and 4.5% in those without OHCA. Multivariate logistic analysis revealed LMT or LAD as the culprit lesion (OR, 12.18; 95% CI, 2.27-65.41; p = 0.004), glucose level (OR, 1.01; 95% CI, 1.00-1.01; p = 0.01), and renal deficiency (OR, 3.35; 95% CI, 1.07-10.53; p = 0.04) as independent predictors of 30-day mortality among AMI patients with OHCA. CONCLUSIONS: In patients with AMI who underwent emergency PCI, 30-day mortality was six times greater in those having presented initially with OHCA compared with those without OHCA. Younger age, absence of diabetes mellitus or dyslipidemia, LMT or LAD as the culprit lesion, and renal deficiency were independent predictors of OHCA. OHCA patient with higher blood glucose level on admission, LMT or LAD as the culprit lesion, or renal deficiency showed worse clinical outcomes.

The association between lipoprotein(a) (Lp[a]) levels and cardiovascular disease has been reported. However, it is still uncertain whether Lp(a) concentration could be a residual risk factor for cardiovascular events after acute coronary syndrome (ACS). The aim of the present study is to evaluate the impact of Lp(a) on long-term cardiovascular outcomes in patients with ACS treated with statins. We studied 1,758 consecutive patients with ACS who underwent emergency percutaneous coronary intervention between 2008 and 2017. We finally enrolled 1,131 patients for whom Lp(a) data were available and who were treated with statins at discharge. Patients were divided into 2 groups according to Lp(a) levels (median Lp(a) 15.0 mg/100 ml). The primary end points were major adverse cardiac events (MACEs), composite of all-cause death, and myocardial infarction up to 5 years. Overall, 107 MACEs (9.5%) were identified. The cumulative incidence of MACE was significantly higher in the high Lp(a) group than the low Lp(a) group (log-rank p = 0.01). After adjustment for other cardiovascular risk factors, the high Lp(a) group had a significantly higher risk of MACE (hazard ratio 1.66, 95% confidence interval 1.05 to 2.61, p = 0.03). Multivariate Cox hazard analysis also showed that increasing Lp(a) as a continuous variable was associated with the incidence of MACE (hazard ratio 1.35 per log Lp[a] 1 increase, 95% confidence interval 1.07 to 1.72, p = 0.01). In conclusion, high Lp(a) level is significantly associated with long-term cardiovascular outcomes in patients with ACS treated with statins after primary percutaneous coronary intervention and is likely to be a potential biomarker for residual risk prediction of future clinical events.

BACKGROUND: Inflammatory status is associated with cardiovascular events in patients with coronary artery disease (CAD) and renal function impairment. Chronic kidney disease (CKD) increases the incidence of cardiovascular events. However, whether the presence of residual inflammatory risk (RIR) and CKD together has a synergistic effect on the long-term clinical outcomes of patients with stable CAD undergoing percutaneous coronary intervention (PCI) remains unclear. METHODS: We assessed 2,948 consecutive patients with stable CAD who underwent the first PCI from 2000 to 2016. Of these, we analyzed the data of patients (2,087) with measurements of high-sensitivity C-reactive protein (hs-CRP) available at follow-up (6-9 months later). High RIR was defined as hs-CRP of >0.6 mg/L according to the median value at follow-up. Patients were classified into four groups: Group 1 (low RIR, non-CKD), Group 2 (high RIR, non-CKD), Group 3 (low RIR, CKD), and Group 4 (high RIR, CKD). We evaluated all-cause mortality and major adverse cardiac events (MACE). The median follow-up period was 5.2 (interquartile range, 1.9-9.9) years. RESULTS: In total, 189 (16.1%) and 128 (11.2%) cases of all-cause mortality and MACE, respectively, were identified during follow-up. The rates of all-cause mortality and MACE were significantly higher in Group 4 than those in the other groups (p<0.001). There was a stepwise increase in the incidence of all-cause mortality and MACE. Upon adjustment for important covariates, the presence of high RIR and/or CKD showed an independent association with a high incidence of MACE and all-cause mortality. CONCLUSIONS: The presence of high RIR and CKD conferred a synergistic adverse effect on the long-term clinical outcomes of patients undergoing PCI.

AIMS: Little is known about the long-term outcomes of ß-blockers use in patients with coronary artery disease (CAD) without myocardial infarction (MI) and reduced ejection fraction (rEF). However, more attention should be paid to the oral administration of ß-blockers in elderly patients who are susceptible to heart failure (HF), sinus node dysfunction, or rate response insufficiency. We aimed to evaluate the long-term impact of ß-blockers in elderly patients with CAD without MI or systolic HF who have undergone percutaneous coronary intervention. METHODS AND RESULTS: A total of 1018 consecutive elderly patients with CAD (mean age, 72 ± 7 years; 77% men) who underwent their first intervention between 2010 and 2018 were included in this study. According to the presence or absence of the use of ß-blockers, 514 patients (50.5%) were allocated to the ß-blocker group, and 504 (49.5%) to the non-ß-blocker group. We evaluated the incidence of 4-point major adverse cardiovascular events (4P-MACE), including cardiovascular death, non-fatal MI, non-fatal stroke, admission for HF, target vessel revascularization (TVR), and all-cause death. We focused on the association between chronotropic incompetence of ß-blockers and incidence of a new HF and analysed the results using an exercise electrocardiogram regularly performed in the outpatient department after percutaneous coronary intervention. During a median follow-up duration of 5.1 years, 83 patients (8.3%) developed 4P-MACE, including cardiovascular death in 17, non-fatal MI in 13, non-fatal stroke in 25, and admission for HF in 39 patients. Additionally, 124 patients (12.2%) had a TVR and 104 (10.2%) died of other causes. Kaplan-Meier analysis showed that the cumulative incidence rate of 4P-MACE in the ß-blocker group was significantly higher than that in the non-ß-blocker group (15.4% vs. 10.0%, log-rank test, P = 0.015). Above all, the cumulative incidence rate of admission for HF in the ß-blocker group was significantly higher (8.8% vs. 3.2%, log-rank test, P < 0.001). The ß-blocker group had significantly lower resting heart rate, stress heart rate, and stress-rest Δ heart rate on exercise electrocardiogram. Multivariate Cox hazard analysis revealed that EF, ß-blocker use, stress-rest Δ heart rate, and CKD were strong independent predictors of admission for HF. CONCLUSIONS: Long-term ß-blocker use was significantly associated with an increased risk of adverse cardiovascular events in elderly patients with CAD without MI or systolic HF. In particular, the chronotropic incompetence action of ß-blockers could increase the risk of admission for HF in elderly patients with CAD without MI and systolic HF, and the present findings warrant further investigation.

In-stent restenosis (ISR) remains the primary concern after a percutaneous coronary intervention (PCI) and is considered to be associated with worse clinical outcomes. However, comparative data on ISR and de novo lesions are rare. Therefore, we aimed to compare PCI-related clinical outcomes between patients with de novo lesions and those with ISR lesions. We undertook a retrospective analysis of patients who had undergone a PCI between 2013 and 2020. The incidences of major adverse cardiac and cerebrovascular events (MACCE) and all-cause death over a 2-year follow-up period were evaluated. In total, 1538 patients were enrolled and divided into two groups: a de novo lesions group (n = 1258, 81.8%) and an ISR lesions group (n = 280, 18.2%). Patients in the ISR lesions group were significantly older, with a higher prevalence of hypertension, diabetes mellitus, dyslipidemia, and chronic kidney disease than those in the de novo lesions group. Kaplan-Meier curves showed no significant between-group differences in the incidence of MACCE (log-rank, p = 0.93) and all-cause death (p = 0.09). After adjustment for other covariates, PCIs for ISR lesions were not found to be significantly associated with MACCE (hazard ratio [HR], 1.10; 95% confidential interval [CI] 0.49-2.49; p = 0.81) and all-cause death (HR, 0.58; 95% CI 0.26-1.31; p = 0.19). PCIs for ISR lesions were not associated with worse clinical outcomes compared with PCIs for de novo lesions.

OBJECTIVES: This study was conducted to use optical coherence tomography (OCT) to compare vascular healing between bioresorbable polymer (BP) and durable polymer (DP) everolimus-eluting stents (EES) in patients with acute coronary syndromes (ACS). BACKGROUND: Whether BP-EES induce better vascular healing compared to contemporary DP-EES remains controversial, especially for ACS. METHODS: In this prospective, randomized, non-inferiority trial, we used OCT to compare 6-month vascular healing in patients with ACS randomized to BP versus DP-EES: percent strut coverage (primary endpoint, non-inferiority margin of 2.0%) and neointimal thickness and percent neointimal hyperplasia (NIH) volume. As an exploratory analysis, morphological factors related to the endpoints and the effect of underlying lipidic plaque on stent healing were evaluated. RESULTS: A total of 104 patients with ACS were randomly assigned to BP-EES (n = 52) versus DP-EES (n = 52). Of these, 86 patients (40 BP-EES and 46 DP-EES) were included in the final OCT analyses. Six-month percent strut coverage of BP-EES (83.6 ± 11.4%) was not non-inferior compared to those of DP-EES (81.6 ± 13.9%), difference 2.0% (lower 95% confidence interval-2.6%), pnon-inferiority = 0.07. There were no differences in neointimal thickness 70.0 ± 33.9 µm versus 67.2 ± 33.9 µm, p = 0.71; and percent NIH volume 7.5 ± 4.7% versus 7.3 ± 5.3%, p = 0.85. By multivariable linear regression analysis, stent type was not associated with percent strut coverage or percent NIH volume; however, percent baseline embedded struts or stent expansion was positively associated with percent NIH volume. Greater NIH volume was observed in lipidic compared with non-lipidic segments (8.7 ± 5.6% vs. 6.1 ± 5.2%, p = 0.005). CONCLUSIONS: Six-month strut coverage of BP-EES was not non-inferior compared to those of DP-EES in ACS patients. Good stent apposition and expansion were independently associated with better vascular healing.
