A novel risk stratification system "Angiographic GRACE Score" for predicting in-hospital mortality of patients with acute myocardial infarction: Data from the K-ACTIVE Registry. J Cardiol 2020; 77:179-185. [PMID: 32921529 DOI: 10.1016/j.jjcc.2020.08.010] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/23/2020] [Revised: 07/18/2020] [Accepted: 08/04/2020] [Indexed: 02/07/2023]
Abstract
BACKGROUND The Global Registry of Acute Coronary Events (GRACE) score is the most accurate risk assessment system for acute myocardial infarction (AMI), which was proposed in Western countries. However, it is unclear whether GRACE score is applicable to the present Japanese patients with a high prevalence of emergent percutaneous coronary intervention (PCI) and vasospasm. This study aimed to clarify the usefulness of GRACE risk score for risk stratification of Japanese AMI patients treated with early PCI and to evaluate a novel risk stratification system, "angiographic GRACE score," which is the GRACE risk score adjusted by the information of the culprit coronary artery and its flow at pre- and post-PCI, to improve its predicting availability. METHODS The subjects were 1817 AMI patients who underwent PCI within 24 h of onset between October 2015 and August 2017 and were registered in Kanagawa Acute Cardiovascular (K-ACTIVE) Registry via survey form. The association between the clinical parameters and in-hospital mortality was investigated. RESULTS A total of 79 (4.3%) in-hospital deaths were identified. The C-statistics for the in-hospital mortality of the GRACE score was 0.86, which was higher than that of the other conventional risk factors, including age (0.65), systolic blood pressure (0.70), heart rate (0.62), Killip classification (0.77), and serum levels of creatinine (0.68) and peak creatine kinase (0.74). The angiographic GRACE score improved the C-statistics from 0.86 of the original GRACE score to 0.89 (p < 0.05). In the setting of the cut-off value at 200, in-hospital mortality in the patients with the angiographic GRACE score <200 was 0.6%, which was relatively lower than those with ≥200, 9.4%. CONCLUSIONS The GRACE score is a useful predictor of in-hospital mortality among Japanese AMI patients in the PCI era. Moreover, the angiographic GRACE score could improve the predicting availability.

Abstract
BACKGROUND Endothelial dysfunction is reportedly associated with worse outcomes in patients with chronic heart failure. Ubiquinol is a reduced form of coenzyme Q10 (CoQ10) that may improve endothelial function. OBJECTIVE We assessed the hypothesis that ubiquinol improves peripheral endothelial function in patients with heart failure with reduced ejection fraction (HFrEF). METHODS In this randomized, double-blind, placebo-controlled, crossover pilot study, 14 patients with stable HFrEF were randomly and blindly allocated to ubiquinol 400 mg/day or placebo for 3 months. After a 1-month washout period, patients were crossed over to the alternative treatment. Before and after each treatment, we assessed peripheral endothelial function using the reactive hyperemia index (RHI) and analyzed it using the natural logarithm of RHI (LnRHI). RESULTS Peripheral endothelial function as assessed by LnRHI tended to improve with ubiquinol 400 mg/day for 3 months (p = 0.076). Original RHI values were also compared, and RHI significantly improved with ubiquinol treatment (pre-RHI 1.57 [interquartile range (IQR) 1.39-1.80], post-RHI 1.74 [IQR 1.63-2.02], p = 0.026), but not with placebo (pre-RHI 1.67 [IQR 1.53-1.85], post-RHI 1.51 [IQR 1.39-2.11], p = 0.198). CONCLUSIONS Ubiquinol 400 mg/day for 3 months led to significant improvement in peripheral endothelial function in patients with HFrEF. Ubiquinol may be a therapeutic option for individuals with HFrEF. Large-scale randomized controlled trials of CoQ10 supplementation in patients with HFrEF are needed.

Abstract
BACKGROUND The efficacy and bleeding complications of direct oral anticoagulant (DOAC) therapy for cancer-associated venous thromboembolism (VTE) in routine clinical practice remain unclear. Moreover, data on long-term outcomes in patients with cancer-associated VTE who received DOAC therapy are limited.Methods and Results:This retrospective study enrolled 1,096 consecutive patients with acute VTE who received warfarin or DOAC therapy between April 2014 and May 2017. The mean follow-up period was 665±490 days. The number of cancer-associated VTE patients who received DOAC therapy was 334. Patients who could not be followed up and those prescribed off-label under-dose DOAC were excluded. Finally, 303 patients with cancer-associated VTE were evaluated. The number of cases of major bleeding and VTE recurrence was 54 (17.8%) and 26 (8.6%), respectively. In the multivariate analysis, the factors correlated with major bleeding were high cancer stage, high performance status, liver dysfunction, diabetes mellitus, and stomach cancer; those correlated with recurrent VTE were initial diagnosis of pulmonary embolism, uterine cancer, and previous cerebral infarction. Major bleeding was an independent risk factor of all-cause death. In the Kaplan-Meier analysis, those who received prolonged DOAC therapy had lower composite major bleeding and recurrent VTE risks than those who did not. CONCLUSIONS In DOAC therapy for cancer-associated VTE, major bleeding prevention is important because it is an independent risk factor of death.

Abstract
The aim of the present study was to determine whether urinary 8-hydroxydeoxyguanosine (8-OHdG), which is a marker of oxidative stress, can predict future cardiovascular death in patients with acute coronary syndrome (ACS). A total of 551 consecutive patients with ACS who underwent admission urinary 8-OHdG measurements were enrolled in this study. The patients were divided into 2 groups according to the optimal cutoff value of admission urinary 8-OHdG determined by a receiver-operating characteristics curve for the prediction of cardiovascular death: a high admission urinary 8-OHdG group, 169 patients with admission urinary 8-OHdG ≥ 17.92 ng/mg creatinine; and a low admission urinary 8-OHdG group, 382 patients with admission urinary 8-OHdG < 17.92 ng/mg creatinine. The patients were followed up for a median period of 34 months. The primary and secondary end points were the incidence of cardiovascular death and major cardiovascular events (MACE) composed of cardiovascular death, non-fatal myocardial infarction, or urgent hospitalization for heart failure. Of the 551 patients, cardiovascular deaths and MACE occurred in 14 (2.5%) and 35 (6.4%), respectively. The Kaplan-Meier estimate of the event-free rate revealed cardiovascular deaths and MACE were more likely in the high admission 8-OHdG group than in the low admission 8-OHdG group (log rank, both P < 0.001). Multiple adjusted Cox proportional hazards analysis indicated that high admission urinary 8-OHdG was an independent predictor of cardiovascular death (hazard ratio [HR] 7.642, P = 0.011) and MACE (HR 2.153, P = 0.049). High admission urinary 8-OHdG levels predict cardiovascular mortality after adjustment in patients with ACS.

Abstract
AIM The purpose of this study is to investigate the impact of arterial stiffness assessed using Cardio-ankle Vascular Index (CAVI) on long-term outcome after acute coronary syndrome (ACS). METHODS A total of 387 consecutive patients (324 males; age, 64±11 years) with ACS were enrolled. We examined CAVI and brachial-ankle pulse wave velocity (ba PWV) as the parameters of arterial stiffness. The patients were divided into two groups according to the cut-off value of CAVI determined using the receiver operating characteristic curve for the prediction of major adverse cardiovascular events (MACE): low-CAVI group, 177 patients with CAVI <8.35; high-CAVI group, 210 patients with CAVI ≥ 8.35. The primary endpoint was the incidence of MACE (cardiovascular death, recurrence of ACS, heart failure requiring hospitalization, or stroke). RESULTS A total of 62 patients had MACE. Kaplan-Meier analysis demonstrated a significantly higher probability of MACE in the high-CAVI group than in the low-CAVI group (median follow-up: 62 months; log-rank, p<0.001). Multivariate analysis suggested that CAVI was an independent predictor of MACE (hazard ratio [HR], 1.496; p=0.02) and cardiovascular death (HR, 2.204; p=0.025), but ba PWV was not. We investigated the incremental predictive value of adding CAVI to the GRACE score (GRS), a validated scoring system for risk assessment in ACS. Stratified by CAVI and GRS, a significantly higher rate of MACE was seen in patients with both higher CAVI and higher GRS than the other groups (p<0.001). Furthermore, the addition of CAVI to GRS enhanced net reclassification improvement (NRI) and integrated discrimination improvement (IDI) (NRI, 0.337, p=0.034; and IDI, 0.028, p=0.004). CONCLUSION CAVI was an independent long-term predictor of MACE, especially cardiovascular death, adding incremental clinical significance for risk stratification in patients with ACS.

Abstract
BACKGROUND Low population density may be associated with high mortality in acute myocardial infarction (AMI) patients. The purpose of this study was to investigate the effect of population density and hospital primary percutaneous coronary intervention (PCI) volume on AMI in-hospital mortality in Japan.Methods and Results:This is a retrospective study of 64,414 AMI patients transported to hospital by ambulances. The main outcome measure was in-hospital mortality. The median population density was 1,147 (interquartile range, 342-5,210) persons/km2. There was a significant negative relationship between population density and in-hospital mortality (OR for a quartile down in population density 1.086, 95% CI 1.042-1.132, P<0.001). Patients in less densely populated areas were more often transported to hospitals with a lower primary PCI volume, and they had a longer distance to travel. By using multivariable analysis, primary PCI volume was found to be significantly associated with in-hospital mortality, but distance to hospital was not. When divided into the low- and high-volume hospitals, using the cut-off value of 115 annual primary PCI procedures, the increase in in-hospital mortality associated with low population density was observed only in patients hospitalized in the low-volume hospitals. CONCLUSIONS Increased in-hospital mortality related to low population density was observed only in AMI patients who were transported to the low primary PCI volume hospitals, but not in those who were transported to high-volume hospitals.

Abstract
BACKGROUND Prompt and potent antiplatelet effects are important aspects of management of ST-elevation myocardial infarction (STEMI) patients undergoing primary percutaneous coronary intervention (PPCI). We evaluated the association between platelet-derived thrombogenicity during PPCI and enzymatic infarct size in STEMI patients.Methods and Results:Platelet-derived thrombogenicity was assessed in 127 STEMI patients undergoing PPCI by: (1) the area under the flow-pressure curve for the PL-chip (PL18-AUC10) using the total thrombus-formation analysis system (T-TAS); and (2) P2Y12reaction units (PRU) using the VerifyNow system. Patients were divided into 2 groups (High and Low) based on median PL18-AUC10during PPCI. PRU levels during PPCI were suboptimal in both the High and Low PL18-AUC10groups (median [interquartile range] 266 [231-311] vs. 272 [217-317], respectively; P=0.95). The percentage of final Thrombolysis in Myocardial Infarction (TIMI) 3 flow was lower in the High PL18-AUC10group (75% vs. 90%; P=0.021), whereas corrected TIMI frame count (31.3±2.5 vs. 21.0±2.6; P=0.005) and the incidence of slow-flow/no-reflow phenomenon (31% vs. 11%, P=0.0055) were higher. The area under the curve for creatine kinase (AUCCK) was greater in the High PL18-AUC10group (95,231±7,275 IU/L h vs. 62,239±7,333 IU/L h; P=0.0018). Multivariate regression analysis identified high PL18-AUC10during PPCI (β=0.29, P=0.0006) and poor initial TIMI flow (β=0.37, P<0.0001) as independent determinants of AUCCK. CONCLUSIONS T-TAS-based high platelet-derived thrombogenicity during PPCI was associated with enzymatic infarct size in patients with STEMI.

Abstract
Abstract
Background
Cardiac troponin (cTn) has been used as the preferred biomarker of myocardial injury for diagnosis of acute myocardial infraction (AMI) by universal definition. A large number of patients formerly classified by creatine kinase (CK) as unstable angina with the WHO criteria in Japan are now diagnosed by cTn as non-ST elevation myocardial infarction (NSTEMI). In this report, we aimed to understand its prevalence and clinical features of AMI diagnosed by using universal definition and the WHO criterial in real world.
Method
This registry is a cross-sectional study of 53 facilities in Kanagawa prefecture of Japan. 4372 AMI patients were enrolled who received primary percutaneous coronary intervention (PCI) between October 1, 2015 and January 29, 2019. Patients were divided into 3 groups, 3268 patients with ST elevation myocardial infarction (STEMI), 628 patients with NSTEMI patients who satisfied the WHO criteria with CK elevation beyond twice upper limit of normal (NSTEMI + CK), and 476 patients with NSTEMI who didn’t satisfy the WHO criteria without CK elevation (NSTEMI-CK).
Result
Baseline clinical characteristics of the study patients are shown in Table 1. In-hospital mortality was significantly lower in patients with NSTEMI-CK (1.9%) than in STEMI (6.0%, P < 0.001) and NSTEMI + CK (5.3%, P < 0.004) (Figure 1). Kaplan-Meier analyses for 0-30 days of cardiac death are shown in Figure 2. From day 0, the Kaplan-Meier curves began to diverge in favor of NSTEMI-CK for up to 30 days.
Conclusion
AMI patients showed distinct clinical features depends on the type. We should be aware of the difference for the diagnosis of AMI by using universal definitions.

Abstract
Abstract
Introduction
Muscle, fat and bone mass may play some roles to keep physical activity and favorable outcome in patients with cardiovascular diseases. However, there is a paucity of data regarding the effects on the prognosis of skeletal muscle, fat, and bone mass in patients with ST-segment elevation myocardial infarction (STEMI).
Purpose
Our purpose was to examine whether skeletal muscle, fat, and bone mass each affect the prognosis after STEMI.
Methods
A total of 354 male patients with STEMI were enrolled in this study. Dual-energy X-ray absorptiometry scan was performed before discharge. All patients were followed up for the primary composite outcome of all-cause death, nonfatal myocardial infarction, nonfatal ischemic stroke, hospitalization for congestive heart failure, and unplanned revascularization.
Results
During a median follow-up of 32 months, 57 patients experienced primary composite outcome. Each of skeletal muscle, fat, and bone mass were indexed by height squared (kg/m2) and divided into two groups using the cut-off value obtained from the maximum Youden index to predict the primary composite outcome. The event rate was significantly higher in patients with low appendicular skeletal muscle mass index (ASMI) (29.2% vs 11.7%, p<0.001), low fat mass index (FMI) (22.9% vs 13.3%, p=0.030), and low bone mass index (23.8% vs 11.6%, p=0.002). After adjustment for age, renal function, diabetes mellitus, infarct size, Killip classification, and body mass index, low ASMI but not FMI (p=0.150) and bone mass index (p=0.159) was independently and significantly associated with the primary composite outcome (adjusted hazard ratio 2.12, 95%-confidence interval 1.05–4.31, p=0.035).
Conclusions
Index about muscle mass rather than fat and bone mass have prognostic impact in male patients with STEMI.

Abstract
Introduction
Sarcopenia, characterized by the loss of skeletal muscle mass and muscle strength, has been demonstrated the importance in cardiovascular diseases including ST-segment elevation myocardial infarction (STEMI). However, there is few data comparing the effects on the prognosis of skeletal muscle mass of upper and lower extremities in STEMI patients.
Purpose
Our purpose was to examine whether skeletal muscle mass of upper and lower extremities affect the prognosis after STEMI.
Methods
A total of 432 patients with STEMI were enrolled in this study. Dual-energy X-ray absorptiometry scan was performed before discharge. Each of upper and lower extremity skeletal muscle masses was indexed by height squared (kg/m2), and divided into two groups using the first quartile value for each sex. All patients were followed up for the primary composite outcome of all-cause death, nonfatal myocardial infarction, nonfatal ischemic stroke, hospitalization for congestive heart failure, and unplanned revascularization.
Results
During a median follow-up of 32 months, 68 patients experienced primary composite outcome. The event rate was significantly higher in patients with low-lower extremity skeletal muscle mass index (LESMI) than in those with high-LESMI (24.3% vs 12.9%, log-rank p<0.001), as well as in those with low-upper extremity muscle mass index than in those with high-upper extremity muscle mass index (UESMI) (19.6% vs 14.5%, log-rank p=0.047). However, after adjustment for age, gender, renal function, diabetes mellitus, infarct size, body mass index, and body fat percentage, only low-LESMI was independently and significantly associated with the primary composite outcome (adjusted hazard ratio for LESMI 2.11, 95%-confidence interval 1.06–4.14, p=0.034, adjusted hazard ratio for UESMI 1.04, 95%-confidence interval 0.52–2.08, p=0.906,).
Conclusions
Decreased muscle mass of lower extremity, rather than upper extremity, might have prognostic impact in patients with STEMI.

Abstract
Background:
We investigated the clinical usefulness of landiolol for rapid atrial fibrillation (AF) in patients with acute decompensated heart failure (ADHF) and identify the patients eligible for landiolol. Methods and Results:
A total of 101 ADHF patients with reduced ejection fraction (HFrEF) with rapid AF were enrolled. Immediately after admission, an initial dose of landiolol was given (1 μg/kg−1/min−1), and then the dose was increased to decrease heart rate (HR) to <110 beats/min and change HR (∆HR) >20% in ≤24 h. Thirty-seven were monitored using right heart catheterization at 3 points (baseline, 1 μg/kg−1/min−1, and maximum dose). We checked the major adverse events (MAE) during initial hospitalization, which included cardiac death, HF prolongation (required i.v. treatment at 30 days), and worsening renal function. The average maximum dose of landiolol was 3.8±2.3 μg/kg−1/min−1. HR (P<0.0001) and pulmonary capillary wedge pressure (P=0.0008) decreased safely. MAE occurred in 39 patients. The patients with left ventricular (LV) end-diastolic volume index <84.0 mL/m2
and mean blood pressure (mean BP) >97 mmHg had less frequent MAE (P<0.0001). Conclusions:
Landiolol was effective for safely controlling rapid AF in patients with HFrEF with ADHF, leading to hemodynamic improvement and avoidance of short-term MAE, especially in patients with relatively smaller LV and higher BP.

Abstract
Trimethylamine N-oxide (TMAO), a metabolite derived from the gut microbiota, is proatherogenic and associated with cardiovascular events. However, the change in TMAO with secondary prevention therapies for ST-segment elevation acute myocardial infarction (STEMI) remains unclear. The purpose of this study was to investigate the sequential change in TMAO levels in response to the current secondary prevention therapies in patients with STEMI and the clinical impact of TMAO levels on cardiovascular events We included 112 STEMI patients and measured plasma TMAO levels at the onset of STEMI and 10 months later (chronic phase). After the chronic-phase assessment, patients were followed up for cardiovascular events. Plasma TMAO levels significantly increased from the acute phase to the chronic phase of STEMI (median: 5.63 to 6.76 μM, P = 0.048). During a median period of 5.4 years, 17 patients experienced events. The chronic-phase TMAO level independently predicted future cardiovascular events (adjusted hazard ratio for 0.1 increase in log chronic-phase TMAO level: 1.343, 95% confidence interval 1.122–1.636, P = 0.001), but the acute-phase TMAO level did not. This study demonstrated the clinical importance of the chronic-phase TMAO levels on future cardiovascular events in patients after STEMI.

Abstract
Background:
Despite the drastic advances in clinical care for patients with acute ST-elevation myocardial infarction (STEMI), female STEMI patients have higher in-hospital mortality rates than male patients. This study assessed the influence of sex on in-hospital mortality in STEMI patients in Kanagawa Prefecture, Japan. Methods and Results:
From October 2015 to June 2018, 2,491 consecutive STEMI patients (23.9% female) who presented to hospital in the 24 h after symptom onset were analyzed. The female patients were 9 years older and less frequently had diabetes, smoking and prior MI than male patients. Pre-hospital managements, including prehospital 12-lead electrocardiography, and symptom-to-door time were similar between the sexes. A door-to-device time ≤90 min was achieved in 61.3% of female cases and in 65.0% of male cases (P=0.13). Reperfusion therapy was provided to 94.6% of female and 97.6% of male patients (P<0.001). In-hospital mortality rate was not significantly different between female and male patients (6.6% vs. 7.8%, P=0.37). On multivariate logistic regression analysis, female sex itself was not associated with in-hospital mortality (OR, 1.52; 95% CI: 0.67–3.47, P=0.32). Conclusions:
There was no sex discrepancy in the in-hospital mortality of STEMI patients in this study. Guideline-based treatment, such as advanced pre-hospital management and a high use of reperfusion therapy might have attenuated the sex-related differences in the in-hospital mortality.

Abstract
BACKGROUND Few reports have evaluated the total antithrombotic effect of multiple antithrombotic agents. Methods and Results: Thrombus formation was evaluated with the Total Thrombus-formation Analysis System (T-TAS®) using 2 types of microchips in 145 patients with stable coronary artery disease receiving oral anticoagulants plus single- or dual-antiplatelet therapy. The PL-chip coated with collagen is designed for analysis of the platelet thrombus formation process under shear stress condition (18 µL/min). The AR-chip coated with collagen and tissue thromboplastin is designed for analysis of the fibrin-rich platelet thrombus formation process under shear stress condition (4 µL/min). The results were expressed as an area under the flow pressure curve (PL18-AUC10and AR4-AUC30, respectively). Bleeding events occurred in 43 patients during a 22-month follow-up. AR4-AUC30was significantly lower in patients with bleeding events than in those without (584 [96-993] vs. 1,028 [756-1,252], P=0.0003). Multivariate logistic regression analysis identified AR4-AUC30(odds ratio 3.18) as a significant predictor of bleeding events, in addition to baseline anemia and usage of the standard dose of direct oral anticoagulants. However, PL18-AUC10was not significantly related to bleeding events. CONCLUSIONS A lower AR4-AUC30level was associated with increasing risk of subsequent bleeding complications in patients with stable coronary artery disease who received multiple antithrombotic agents.

Abstract
Background Thinning of the fibrous cap of atherosclerotic plaque is a major component of plaque vulnerability. The high resolution of optical coherence tomography (OCT) provides an accurate measurement of fibrous-cap thickness. Endothelial dysfunction is associated with inflammation and enhanced local expression of matrix metalloproteinases. We investigated the association between endothelial dysfunction and OCT-derived thin-cap fibroatheroma (TCFA) in patients with acute coronary syndromes (ACS). Methods Seventy-four patients with ACS, who underwent both OCT examinations of the culprit lesion before percutaneous coronary intervention and peripheral endothelial function assessment as assessed by logarithmic value of reactive hyperemia index (Ln_RHI), were enrolled. Age-, sex-, hypertension-, and diabetes-matched non-coronary artery disease (non-CAD) patients were also enrolled (n=15). Results Ln_RHI levels were significantly lower in ACS patients compared with non-CAD patients (0.56±0.26 vs 0.74±0.22, P=0.01). Furthermore, the Ln_RHIs of ACS patients with TCFA (n=44) were significantly lower than those of ACS patients without TCFA (n=30) (0.50±0.24 vs 0.65±0.26, P=0.01). There was a weak but significant positive correlation between Ln_RHI and fibrous-cap thickness (Spearman's ρ=0.25, P=0.03). Multivariate logistic regression analysis identified lower Ln_RHI as an independent factor associated with TCFA in ACS patients (OR per 0.1 increase in Ln_RHI: 0.78 [95% CI: 0.62-0.98], P=0.03). Conclusion Advanced endothelial dysfunction significantly correlates with a thin fibrous cap of coronary plaques in patients with ACS.

Abstract
Background:
The aim of this study was to clarify the clinical impact of activities of daily living (ADL) using the Japanese Registry of All Cardiac and Vascular Diseases-Diagnosis Procedure Combination (JROAD-DPC) database. Methods and Results:
From April 2012 to March 2014, the JROAD-DPC database included 206,643 patients with acute coronary syndrome (ACS; n=49,784), heart failure (HF; n=136,878), or aortic aneurysm/dissection (Aorta; n=19,981). We divided them into 3 categories with regard to age (low, 20–59 years; middle, 60–79 years; high, ≥80 years) and admission ADL (low, Barthel index [BI] 0–70; middle, BI 75–95; high, BI 100). ACS, HF, and Aorta patients with low ADL had higher in-hospital mortality rates (18.3%, 16.7%, and 33.4%) than those with middle or high ADL (P<0.001, χ2 test). On multivariable analysis, BI on admission was associated with in-hospital mortality of ACS (OR, 0.986 per 1 BI; P<0.001), HF (OR, 0.986 per 1 BI; P<0.001), and Aorta (OR, 0.986 per 1 BI; P<0.001), adjusted for gender, age, body mass index, hypertension, diabetes mellitus, dyslipidemia, and the Charlson comorbidity index. Moreover, patients with low age and low ADL had a higher in-hospital mortality rate than those with high age and high ADL in regard to HF (8.6% vs. 6.0%). Conclusions:
According to JROAD-DPC data, assessment of admission ADL is important in patients with cardiovascular disease.

Abstract
Anatomical measurements obtained by intracoronary imaging devices are reported to correlate significantly with fractional flow reserve (FFR). Instantaneous wave-free ratio (iFR) is a nonhyperemic index of stenosis severity with discordant reports regarding its accuracy in relation to FFR. There is no information on the correlation of iFR with measurements derived from intracoronary imaging devices. The purpose of this study was to assess the relationship among iFR, intravascular ultrasound (IVUS), and optical frequency domain imaging (OFDI) parameters. Eighty lesions in 72 patients who underwent elective angiography and had intermediate lesions were enrolled. All lesions were assessed by iFR, FFR, IVUS, and OFDI. iFR was ≤ 0.89 in 21 (26%) lesions and FFR was ≤ 0.80 in 41 (51%) lesions. iFR correlated significantly with both IVUS-derived minimum lumen area (MLA) (r = 0.375, p = 0.003) and OFDI-derived MLA (r = 0.357, p = 0.005). FFR also correlated significantly with both IVUS-derived MLA (r = 0.472, p < 0.001) and OFDI-derived MLA (r = 0.445, p < 0.001). Among the lesions with FFR ≤ 0.80, iFR > 0.89 (mismatch) was observed in 20 lesions. There was no lesion with iFR ≤ 0.89 (reverse mismatch) among the lesions with FFR > 0.80. The lesion location among three major coronary vessels was related with the discrepancy between iFR and FFR (p = 0.007). In conclusion, iFR and FFR showed a significant correlation with IVUS and OFDI measurements. The discrepancy of iFR and FFR was associated with the lesion locations.

Abstract
A 28-year-old man without coronary risk factors was admitted to the hospital with acute coronary syndromes (ACS). The angiogram and intravascular ultrasound revealed myocardial bridge (MB) in the mid-left anterior descending artery and flow-limiting plaque located 15.4 mm proximal to MB. The culprit lesion was treated only with drug-coated balloon, considering the patient's extremely young age. This case suggests that an accelerated formation of plaque caused by MB appeared to contribute to the development of ACS; thus, MB should be considered as an important cause of ACS in young patients with low cardiovascular risk.

Abstract
Background Impaired glucose metabolism is an established risk factor for coronary artery disease. Previous studies revealed that glycemic variability (GV) is also important for glucose metabolism in patients with acute coronary syndrome (ACS). We explored the association between GV and prognosis in patients with ACS. Methods A total of 417 patients with ACS who received reperfusion wore a continuous glucose monitoring system (CGMS) in a stable phase after admission and were monitored for at least 24 consecutive h. The mean amplitude of glycemic excursion (MAGE) was calculated as a marker of GV. We divided into two groups based on the highest tertile levels of MAGE (MAGE = 52 mg/dl). The groups were followed up for a median of 39 months [IQR 24–50 months]. The primary endpoint was the incidence of major adverse cardiovascular and cerebrovascular events (MACCE). Result During follow-up, 66 patients experienced MACCE (5 patients had cardiovascular death, 14 had recurrence of ACS, 27 had angina requiring revascularization, 8 had acute decompensated heart failure, and 16 had a stroke). MACCE was more frequently observed in the high MAGE group (23.5% vs. 11.6%, p = 0.002). In multivariate analysis, high MAGE was an independent predictive factor of poor prognosis for MACCE (odds ratio, 1.84; 95% confidence interval, 1.01–3.36; p = 0.045). Conclusion Glycemic variability determined with a CGMS is a predictor of prognosis in patients with ACS without severe DM. Trial registration UMIN 000010620. Registered April 1st 2012
