Abstract
BACKGROUND Obesity is often considered a risk factor for cardiovascular disease, but recent studies have shown conflicting results regarding the effect of BMI on the prognosis of coronary artery disease (CAD). This study aimed to evaluate the relationship between BMI and clinical outcomes of CAD according to sex in a Korean population. METHODS A total of 3476 patients with a significant CAD who underwent percutaneous coronary intervention (PCI) were enrolled. Patients were classified as follows according to BMI using the Asia-Pacific cutoff points: underweight (<18.5 kg/m 2 ), normal weight (18.5-22.9 kg/m 2 ), overweight (23.0-24.9 kg/m 2 ) and obese (≥25 kg/m 2 ) patients. Underweight and normal weight patients were further categorized into the lower BMI group, whereas overweight and obese patients were categorized into the higher BMI group. The primary endpoint was all-cause mortality. RESULTS Among women, the higher BMI group showed poor clinical features in the prevalence of hypertension and chest pain presentation, and among men, the higher BMI group had a significantly lower rate of chronic renal failure. At the end of the follow-up period (median 53.5 months), the all-cause mortality rate was lower in the higher BMI group in men, and cardiovascular death and stroke rates were significantly lower in the higher BMI group in women. CONCLUSION In Korean CAD patients treated with PCI, inverse correlations were observed between the clinical outcomes and BMI, but there were differences between men and women.

Abstract
BACKGROUND The optimal antiplatelet therapy (APT) for patients undergoing non-cardiac surgery within 1 year after percutaneous coronary intervention (PCI) is not yet established. METHODS Patients who underwent non-cardiac surgery within 1 year after second-generation drug-eluting stent implantation were included from a multicenter prospective registry in Korea. The primary endpoint was 30-day net adverse clinical event (NACE), including all-cause death, major adverse cardiovascular event (MACE), and major bleeding events. Covariate adjustment using propensity score was performed. RESULTS Among 1130 eligible patients, 708 (62.7%) continued APT during non-cardiac surgery. After propensity score adjustment, APT continuation was associated with a lower incidence of NACE (3.7% vs 5.5%; adjusted odds ratio [OR], 0.48; 95% confidence interval [CI], 0.26-0.89; P = .019) and MACE (1.1% vs 1.9%; adjusted OR, 0.35; 95% CI, 0.12-0.99; P = .046), whereas the incidence of major bleeding events was not different between the 2 APT strategies (1.7% vs 2.6%; adjusted OR, 0.61; 95% CI, 0.25-1.50; P = .273). CONCLUSIONS The APT continuation strategy was chosen in a substantial proportion of patients and was associated with the benefit of potentially reducing 30-day NACE and MACE with similar incidence of major bleeding events, compared with APT discontinuation. This study suggests a possible benefit of APT continuation in non-cardiac surgery within 1 year of second-generation drug-eluting stent implantation.

Abstract
BACKGROUND Current guidelines recommend that patients with established atherosclerotic cardiovascular disease (ASCVD) use high-intensity statin therapy to lower low-density lipoprotein (LDL)-cholesterol levels by at least 50%, irrespective of age. However, in real-world practice, there is reluctance to maintain statin use in response to side-effects, particularly statin-associated muscle symptoms (SAMS). Moreover, no randomized trial has been conducted on the safety of statin therapy in elderly patients. TRIAL DESIGN This investigator-initiated, multicenter, randomized clinical trial aimed to investigate the incidence of SAMS and its effect on LDL-cholesterol levels in elderly patients with established ASCVD. Eligible patients were aged 70 years or older with established ASCVD. Consecutive patients who met the inclusion criteria were randomized in a 1:1 fashion to receive either intensive statin monotherapy (rosuvastatin 20 mg) or combination therapy (rosuvastatin/ezetimibe, 5/10 mg). The primary endpoint of the study is SAMS at 6 months with regard to treatment strategy. Positive SAMS results are defined as patients with a proposed statin myalgia index score of 7 or higher. The key secondary end-points are target LDL-cholesterol achievement (LDL < 70 mg/dL), incidence of myopathy, rhabdomyolysis, frequency of drug discontinuation, and creatinine kinase, aspartate transaminase, alanine transaminase, total cholesterol, LDL-cholesterol, high-density lipoprotein-cholesterol, triglyceride, and highly sensitive C-reactive protein levels at 6 months. CONCLUSIONS The SaveSAMS study is a multicenter, randomized trial that will compare the incidence of SAMS in patients with established ASCVD who are 70 years or older on intensive statin monotherapy to that combination therapy.

Abstract
The atomic masses of ^{55}Sc, ^{56,58}Ti, and ^{56-59}V have been determined using the high-precision multireflection time-of-flight technique. The radioisotopes have been produced at RIKEN's Radioactive Isotope Beam Factory (RIBF) and delivered to the novel designed gas cell and multireflection system, which has been recently commissioned downstream of the ZeroDegree spectrometer following the BigRIPS separator. For ^{56,58}Ti and ^{56-59}V, the mass uncertainties have been reduced down to the order of 10 keV, shedding new light on the N=34 shell effect in Ti and V isotopes by the first high-precision mass measurements of the critical species ^{58}Ti and ^{59}V. With the new precision achieved, we reveal the nonexistence of the N=34 empirical two-neutron shell gaps for Ti and V, and the enhanced energy gap above the occupied νp_{3/2} orbit is identified as a feature unique to Ca. We perform new Monte Carlo shell model calculations including the νd_{5/2} and νg_{9/2} orbits and compare the results with conventional shell model calculations, which exclude the νg_{9/2} and the νd_{5/2} orbits. The comparison indicates that the shell gap reduction in Ti is related to a partial occupation of the higher orbitals for the outer two valence neutrons at N=34.

Abstract
Anemia is a well-known risk factor for cardiovascular disease. However, there are limited data on whether anemia on admission is a long-term prognostic factor in acute coronary syndrome (ACS) patients undergoing percutaneous coronary intervention. We sought to evaluate the prevalence and prognostic consequences of anemia in patients with ACS treated with percutaneous coronary intervention in Korea. We retrospectively enrolled 1930 consecutive patients. Among the anemic population (hemoglobin [Hb] < 13 g/dL in men, and < 12 g/dL in women), we classified patients with Hb ≥ 7 g/dL, <10 d/dL as moderate anemia, other cases classified as mild anemia. Among patients with normal hemoglobin levels, we classified those with Hb > 16.5 g/dL in men, and > 16.0 g/dL in women, as having high hemoglobin. We examined the relationship between anemia with all-cause mortality and secondary outcomes - including cardiovascular mortality, myocardial infarction, stroke, and repeat revascularization. We classified 3.3%, 21.5%, and 5.3% of patients as moderate anemia, mild anemia, and high hemoglobin, respectively. During a median follow-up of 67.2 (interquartile range; 46.8-88.5) months, 74 (3.8%) patients died. Compared with patients with normal hemoglobin, we detected a significantly increased risk for all-cause mortality in patients with anemia (adjusted hazard ratios for moderate and mild anemia, respectively: 8.26 [95% confidence interval: 3.98-17.15], P < .001 and 2.60 [1.54-4.40], P < .001). Among patients with ACS, anemia is prevalent and is strongly associated with increased mortality and cardiovascular events. Clinical trials will prospectively evaluate the efficacy of treatment for anemia on the outcomes of patients with ACS.

Abstract
Abstract
Background
Antiplatelet therapy (APT) in patients undergoing non-cardiac surgery (NCS) after percutaneous coronary intervention (PCI) is still on debate due to its opposite effects which are to prevent from cardiovascular events and to cause bleeding. There is no apparent consensus on how to determine perioperative APT strategy within 1 year after PCI. Therefore, we investigated the risk and benefit of APT in NCS within 1 year after PCI.
Methods
Patients undergoing NCS after PCI with second-generation drug-eluting stents are retrospectively included from multicenter cohort of 8 medical centers in Korea. Perioperative clinical event within 30 days after NCS was recorded. Net adverse clinical event (NACE) including all cause death, major adverse cardiac event (MACE, a composite of cardiac death, myocardial infarction, and stent thrombosis) and major bleeding were evaluated. To overcome bias, propensity score covariate adjustment was performed using logistic regression analysis to generate propensity scores for patients of both APT strategies.
Results
Total 1130 patients (median age 69 years, female 30.5%) undergoing NCS within 1 year after PCI were eligible in the cohort. Study population included 55.1% patients suffered from ACS and 22.5% underwent complex PCI. NCS included 45.8% intermediate-to-high risk surgery and 10.7% urgent or emergent surgery. APT was continued during NCS in 62.7% of the patients. More patients continued DAPT (48% vs. 32%, p<0.001) among the patients who underwent NCS within 6 months after PCI than those who underwent NCS after 6 months. There were 49 NACE (4.3%), 16 MACE (1.4%) and 23 major bleeding events (2.0%), respectively. Continuing APT was associated with a lower risk of NACE (Adjusted hazard ratio [HR], 0.49; 95% confidence interval [CI], 0.27–0.89; p=0.020)) and MACE (Adjusted HR, 0.35; 95 CI, 0.12–0.96; p=0.042). Subgroup analysis showed a tendency that continuing APT might be favorable than discontinuing APT in terms of MACE in patients who were diagnosed with ACS, underwent complex PCI, or underwent NCS within 6 months after PCI.
Conclusions
About two thirds of the patients were continuing APT during NCS. Our findings may support a careful consideration of APT continuation for some of the patients who are undergoing NCS within 1 year after PCI.

Abstract
The incidence and impact of malnutrition on acute coronary syndrome (ACS) remain unclear. This study aimed to evaluate the prevalence, clinical relevance, and prognostic outcomes of malnutrition in patients with ACS treated with percutaneous coronary intervention. This retrospective study included 1930 consecutive patients with ACS undergoing percutaneous coronary intervention and assessed their nutritional status using 3 scoring systems: Controlling Nutritional Status score, nutritional risk index (NRI), and prognostic nutritional index (PNI). The primary endpoint was all-cause mortality. The Controlling Nutritional Status, NRI, and PNI scores showed that 5.2%, 17.5%, and 3.9% of patients were moderately or severely malnourished, respectively. During a median follow-up of 67.2 months (interquartile range: 46.8-88.5 months), 74 (3.8%) patients died. Malnutrition was associated with a significantly increased risk for all-cause mortality compared with good nutrition (adjusted hazard ratios for moderate and severe malnutrition, respectively: 5.65 [95% confidence interval: 3.27-9.78] and 15.26 [7.50-31.05] for the NRI score, 5.53 [2.10-14.49] and 11.08 [5.69-21.59] for the PNI; P < .001). The current findings demonstrated that malnutrition is prevalent among patients with ACS and is closely associated with increased mortality. Further study is needed to evaluate the effects of nutritional interventions on the outcomes of patients with ACS.

Abstract
Background Although antiplatelet therapy (APT) has been recommended to balance ischemic‐bleeding risks, it has been left to an individualized decision‐making based on physicians' perspectives before non‐cardiac surgery. The study aimed to assess the advantages of a consensus among physicians, surgeons, and anesthesiologists on continuation and regimen of preoperative APT in patients with coronary drug‐eluting stents. Methods and Results A total of 3582 adult patients undergoing non‐cardiac surgery after percutaneous coronary intervention with second‐generation stents was retrospectively included from a multicenter cohort. Physicians determined whether APT should be continued or discontinued for a recommended period before non‐cardiac surgery. There were 3103 patients who complied with a consensus decision. Arbitrary APT, not based on a consensus decision, was associated with urgent surgery, high bleeding risk of surgery, female sex, and dual APT at the time of preoperative evaluation. Arbitrary APT independently increased the net clinical adverse event (adjusted odds ratio [ORadj], 1.98; 95% CI, 1.98–3.11), major adverse cardiac event (ORadj, 3.11; 95% CI, 1.31–7.34), and major bleeding (ORadj, 2.34; 95% CI, 1.45–3.76) risks. The association was consistently noted, irrespective of the surgical risks, recommendations, and practice on discontinuation of APT. Conclusions Most patients were treated in agreement with a consensus decision about preoperative APT based on a referral system among physicians, surgeons, and anesthesiologists. The risk of perioperative adverse events increased if complying with a consensus decision was failed. Registration URL: https://www.clinicaltrials.gov; Unique identifier: NCT03908463.

Abstract
Mass-separated ^{187}Ta_{114} in a high-spin isomeric state has been produced for the first time by multinucleon transfer reactions, employing an argon gas-stopping cell and laser ionization. Internal γ rays revealed a T_{1/2}=7.3±0.9 s isomer at 1778±1 keV, which decays through a rotational band with perturbations associated with the approach to a prolate-oblate shape transition. Model calculations show less influence from triaxiality compared to heavier elements in the same mass region. The isomer-decay reduced E2 hindrance factor f_{ν}=27±1 supports the interpretation that axial symmetry is approximately conserved.

Abstract
Background Continuing antiplatelet therapy (APT) has been generally recommended during noncardiac surgery, but it is uncertain if preoperative discontinuation of APT has been avoided or harmful in patients with second-generation drug-eluting coronary stents. Methods and Results Patients undergoing noncardiac surgery after second-generation drug-eluting coronary stent implantation were assessed in a multicenter cohort in Korea. Net adverse clinical events within 30 days postoperatively, defined as all-cause death, major adverse cardiac events, and major bleeding, were evaluated. Of 3582 eligible patients, 49% patients discontinued APT during noncardiac surgery. The incidence of net adverse clinical events was comparable between patients with continuation versus discontinuation (4.1% versus 3.4%; P=0.257) of APT during noncardiac surgery. Perioperative discontinuation of APT did not impact on net adverse clinical events (adjusted hazard ratio [HR], 1.00; 95% CI, 0.69-1.44; P=0.995). In subgroup analysis, patients undergoing intra-abdominal surgery were exposed to less risk of major bleeding by discontinuing APT (adjusted HR, 0.26; 95% CI, 0.08-0.91; P=0.035). Prolonged discontinuation of APT for ≥9 days was associated with higher risk of a major adverse cardiac event compared with continuing APT (adjusted HR, 3.38; 95% CI, 1.36-8.38; P=0.009). Conclusions APT was discontinued preoperatively in almost half of patients with second-generation drug-eluting coronary stents. Our explorative analysis showed that there was no significant impact of discontinuing APT on the risk of perioperative adverse events except that discontinuing APT may be associated with decreased hemorrhagic risk in patients undergoing intra-abdominal surgery.

Abstract
There are some similarities in clinical features between Takotsubo cardiomyopathy during the peripartum period (PTCM) and peripartum cardiomyopathy (PPCM). Both conditions present as acute heart failure and decreased left ventricular (LV) ejection fraction in the peripartum period in previously heart-healthy women. The present study aimed to evaluate the differences in clinical features and outcomes between PTCM and PPCM. Between January 2004 and December 2016, 37 consecutive patients who demonstrated LV dysfunction during the peripartum period without previous heart disease were recruited retrospectively. The clinical, laboratory, and echocardiographic data of these patients were comprehensively reviewed. Twenty-one (57%) and 16 (43%) patients were classified into PPCM and PTCM groups, respectively, based on echocardiographic findings. The initial LV ejection fraction did not differ significantly between the 2 groups. However, all patients with PTCM showed complete recovery of LV ejection fraction at the 1-month follow-up. However, among 20 patients with PPCM who underwent 1-month echocardiography, only 6 (30%) showed complete recovery of LV ejection fraction at the 1-month follow-up. At the 12-month follow-up, only 10 patients showed complete recovery of LV ejection fraction. The incidence of PTCM was much higher than expected. Although LV dysfunction was similar at the initial diagnosis, the prognosis of LV recovery was more favorable in PTCM than in PPCM. Therefore, physicians should differentiate these two diseases entities, although they have several similarities in acute LV dysfunction.

Abstract
AbstractIn patients requiring dual antiplatelet therapy (DAPT) who also have an indication to be treated with oral anticoagulant (OAC) drugs, aspirin withdrawal reduces the risk of bleeding. There is limited data on the pharmacodynamic effects associated with adding a nonvitamin K antagonist OAC on a background of aspirin and a P2Y12 inhibitor as well as dropping aspirin. Seventy-five patients on DAPT (aspirin plus clopidogrel) were randomized to DAPT plus high-dose edoxaban (60 mg once daily, Group A), DAPT plus low-dose edoxaban (30 mg once daily, Group B), or DAPT only (Group C) for 10 ± 2 days (Phase I). Afterwards, Groups A and B interrupted aspirin and maintained clopidogrel plus edoxaban for 10 ± 2 days, while patients in Group C maintained DAPT (Phase II). Platelet aggregation and clot kinetics were assessed at baseline, end of Phase I, and end of Phase II using thrombelastography (TEG), light transmittance aggregometry (LTA), VerifyNow P2Y12, and serum thromboxane-B2. The primary endpoint was the comparison of maximum amplitude (MA) measured by TEG, a measure of clot strength, between patients on DAPT plus high-dose edoxaban and patients on DAPT only. Edoxaban prolonged in a dose-dependent manner speed of thrombin generation (TEG R; Group A: 7.7 [6.8–8.7] vs. Group B: 7.4 [6.4–8.5] vs. Group C: 6.3 [5.7–7.0]; p = 0.05) but did not affect other markers of clot kinetics, including TEG MA (Group A: 63 [61–64] vs. Group B: 65 [63–67] vs. Group C: 64 [63–65]; p = 0.10). After aspirin discontinuation, platelet reactivity assessed by LTA using thrombin receptor activating peptide as agonist increased to a greater extent with low-dose edoxaban. Stopping aspirin did not affect markers of P2Y12 reactivity and had no or marginal effects on clot kinetics, but increased markers sensitive to cyclooxygenase-1 blockade.

Abstract
BACKGROUND Cyclooxygenase-2 (COX2) plays a role in the formation of prostaglandins, which contribute to the inflammation involved in atherosclerosis. However, the role of the COX2 -765G>C polymorphism in susceptibility to coronary artery disease (CAD) is controversial. OBJECTIVE To identify the association between COX2 -765G>C polymorphism with CAD risk in Korean patients. We recruited 622 patients who were diagnosed to have coronary artery disease and 202 controls who did not have history and vascular disease risk factors. METHODS Using polymerase chain reaction-restriction fragment length polymorphism, the COX2 -765G>C polymorphism was analyzed in 622 Korean patients who received percutaneous coronary intervention and in 202 healthy control subjects. RESULTS The GC+CC genotype frequencies of the -765G>C polymorphism were significantly different between the CAD and control groups. The COX2 -765G>C polymorphism showed peculiar associations with CAD according to the presence of hyperlipidemia and plasma folate levels. However, there were no associations between the -765G>C polymorphism and the rates of hypertension, diabetes mellitus, or homocysteine levels. CONCLUSION This study suggests that the COX2 -765G>C polymorphism is a possible genetic determinant for the risk of CAD, and an individual risk factor in Koreans. Thus, further association studies between the COX2 polymorphism and atherosclerotic-related diseases such as cerebrovascular or cardiovascular diseases in other races or ethnicities will be needed.

Abstract
BACKGROUND There are no previous data on serial changes in neutrophil gelatinase-associated lipocalin (NGAL) levels in ST-segment elevation myocardial infarction (STEMI) patients before and after a primary percutaneous coronary intervention (pPCI). The aim of the present study was to evaluate the prognostic value of serial NGAL measurements in patients with STEMI treated by pPCI. MATERIALS AND METHODS We identified 169 STEMI patients who underwent pPCI within 12 h of symptom onset and had plasma NGAL measurements before (pre-NGAL) and 6 h after (post-NGAL) pPCI. The primary endpoint was 30-day all-cause mortality, including cardiac death, whereas the secondary endpoint was the change in NGAL levels from before to after pPCI. RESULTS The mean pre-NGAL and post-NGAL levels were 109.2±76.1 and 93.3±83.8 ng/ml, respectively. Thirty-day mortality occurred in 12 (7.1%) patients. In terms of changes in serial NGAL levels, post-NGAL levels were decreased in 132 (79%) patients. Patients with elevated post-NGAL levels showed increased mortality compared with patients with decreased post-NGAL levels (P=0.005). Multivariate analyses indicated that old age and high post-NGAL levels were independent risk factors for 30-day mortality. CONCLUSION In a large percentage of STEMI patients, plasma post-pPCI NGAL levels were decreased compared with pre-pPCI NGAL levels, even with the administration of potentially nephrotoxic contrast medium. Post-NGAL levels seemed to be superior to pre-NGAL levels for the prediction of 30-day mortality outcome.

Abstract
The masses of ^{246}Es, ^{251}Fm, and the transfermium nuclei ^{249-252}Md and ^{254}No, produced by hot- and cold-fusion reactions, in the vicinity of the deformed N=152 neutron shell closure, have been directly measured using a multireflection time-of-flight mass spectrograph. The masses of ^{246}Es and ^{249,250,252}Md were measured for the first time. Using the masses of ^{249,250}Md as anchor points for α decay chains, the masses of heavier nuclei, up to ^{261}Bh and ^{266}Mt, were determined. These new masses were compared with theoretical global mass models and demonstrated to be in good agreement with macroscopic-microscopic models in this region. The empirical shell gap parameter δ_{2n} derived from three isotopic masses was updated with the new masses and corroborates the existence of the deformed N=152 neutron shell closure for Md and Lr.

Abstract
INTRODUCTION Variability in individual response profiles to antiplatelet therapy, in particular clopidogrel, is a well-established phenomenon. Genetic variations of the cytochrome P450 (CYP) 2C19 enzyme, a key determinant in clopidogrel metabolism, have been associated with clopidogrel response profiles. Moreover, the presence of a CYP2C19 loss-of-function allele is associated with an increased risk of atherothrombotic events among clopidogrel-treated patients undergoing percutaneous coronary interventions (PCI), prompting studies evaluating the use of genetic tests to identify patients who may be potential candidates for alternative platelet P2Y12 receptor inhibiting therapies (prasugrel or ticagrelor). Areas covered: The present manuscript provides an overview of genetic factors associated with response profiles to platelet P2Y12 receptor inhibitors and their clinical implications, as well as the most recent developments and future considerations on the role of genetic testing in patients undergoing PCI. Expert commentary: The availability of more user-friendly genetic tests has contributed towards the development of many ongoing clinical trials and personalized medicine programs for patients undergoing PCI. Results of pilot investigations have shown promising results, which however need to be confirmed in larger-scale studies to support the routine use of genetic testing as a strategy to personalize antiplatelet therapy and improve clinical outcomes.

Abstract
The magnetocaloric effect (MCE) is described by the change in temperature of a material by magnetic field variation and is a crucial subject in magnetism; it is motivated by the desire to enhance energy-efficient magnetic refrigeration for clean technology. Despite the recent discovery of the giant cryogenic MCE in double perovskites, the role of magnetic anisotropy has not yet been clearly discussed, because of the averaging effect of polycrystalline samples. Here, we investigated the anisotropic MCE in the single-crystal double perovskite Gd2CoMnO6. In addition to the ferromagnetic order of the Co2+ and Mn4+ moments, the large Gd3+ moments align below T Gd = 21 K, exhibiting an isotropic nature. Because of the intricate temperature development of magnetically hysteretic behaviour and metamagnetism, the change in magnetic entropy along the c-axis appears to be relatively small. On the contrary, the smaller but almost reversible magnetization perpendicular to the c-axis leads to a large MCE with a maximum entropy change of 25.4 J/kg·K. The anisotropic MCE generates a giant rotational MCE, estimated as 16.6 J/kg·K. Our results demonstrate the importance of magnetic anisotropy for understanding the MCE and reveal essential clues for exploring suitable magnetic refrigerant compounds aiming at magnetic functional applications.

Abstract
Dual antiplatelet therapy (DAPT) with aspirin and a P2Y12 receptor antagonist represents the current standard of care to prevent atherothrombotic recurrences in patients with acute coronary syndrome (ACS). However, despite the use of DAPT, the recurrence rate of cardiovascular ischemic events still remains high. This persistent risk may be in part attributed to the sustained activation of the coagulation cascade leading to generation of thrombin, which may continue to play a key role in thrombus formation. The use of vitamin K antagonists (VKAs) as a strategy to reduce atherothrombotic recurrences after an ACS has been previously tested, leading to overall unfavorable outcomes due to the high risk of bleeding complications. The recent introduction of non-VKA oral anticoagulants (NOACs), characterized by a better safety profile and ease of use compared with VKA, has led to a reappraisal of the use of oral anticoagulant therapy for secondary prevention in ACS patients. The present article provides an overview of the rationale and prognostic role of oral anticoagulant therapy in ACS patients as well as recent updated clinical data, in particular with NOACs, in the field and future perspectives on this topic.

Abstract
OBJECTIVE Bone morphogenetic proteins (BMP) belong to the transforming growth factor beta superfamily of proteins. This study was performed to evaluate the association of BMP gene polymorphisms with acute renal allograft rejection (AR) and graft dysfunction (GD) in Koreans. METHODS Three hundred thirty-one patients who had kidney transplantation procedures were recruited. Transplantation outcomes were determined in terms of AR and GD criteria. We selected six single nucleotide polymorphisms (SNPs): rs1979855 (5' near gene), rs1049007 (Ser87Ser), rs235767 (intron), rs1005464 (intron), rs235768 (Arg190Ser), and rs3178250 (3; untranslated region). RESULTS Among the six SNPs tested, the rs235767, rs1005464, and rs3178250 SNPs were significantly associated with AR (P < .05). The rs1049007 and rs235768 SNPs also showed an association with GD (P < .05). CONCLUSIONS In conclusion, these results suggest that the BMP2 gene polymorphism may be related to the development of AR and GD in kidney transplant recipients.

Abstract
Purpose The number of citations that an article has received reflects its impact on a particular research area. The aim of this study was to identify the 100 most-cited articles focused on ultrasound (US) imaging and to analyze the characteristics of these articles. Methods We determined the 100 most-cited articles on US imaging via the Web of Science database, using the search term. The following parameters were used to analyze the characteristics of the 100 most-cited articles: publication year, journal, journal impact factor, number of citations and annual citations, authors, department, institution, country, type of article, and topic. Results The number of citations for the 100 most-cited articles ranged from 1849 to 341 (median: 442.0) and the number of annual citations ranged from 108.0 to 8.1 (median: 22.1). The majority of articles were published in 1990 - 1999 (39 %), published in radiology journals (20 %), originated in the United States (45 %), were clinical observation studies (67 %), and dealt with the vessels (35 %). The Department of Internal Medicine at the University of California and the Research Institute of Public Health at the University of Kuopio (n = 4 each) were the leading institutions and Salonen JT and Salonen R (n = 4 each) were the most prolific authors. Conclusion Our study presents a detailed list and analysis of the 100 most-cited US articles, which provides a unique insight into the historical development in this field.

Abstract
In spite of treatment with the current standard of care antiplatelet regimens including dual antiplatelet therapy, recurrence rates of ischemic events remain elevated for high-risk patients with atherosclerotic disease. This may be in part attributed to the fact that other key platelet activation pathways remain uninhibited and can thus continue to trigger platelet activation and lead to thrombotic complications. Thrombin is a powerful inducer of platelet activation and mediates its effects directly on platelets through protease activator receptors (PARs), particularly the PAR-1 subtype, making PAR-1 inhibition an attractive approach for reducing atherothrombotic events. These observations have led to the development of several PAR-1 antagonists. Vorapaxar is a direct inhibitor of PAR-1 and the only agent of this class approved for the prevention of recurrent ischemic events in patients with prior myocardial infarction or peripheral artery disease. In the present manuscript, we present a review of the pathophysiologic role of thrombin on thrombotic complications, the impact of vorapaxar on outcomes, including the most recent updates deriving from clinical trials, as well as future perspectives in the field.

Abstract
RATIONALE An intracardiac cystic mass is a rare type of mass found in the left atrium. The differential diagnosis of an intracardiac cystic mass includes hydatid cysts, bronchogenic cysts, intracardiac varices, and hemorrhages in some tumor types, including myxoma. PATIENT CONCERNS We present the case of a 68-year-old woman who presented with episodic dyspnea. DIAGNOSES-INTERVENTIONS-OUTCOMES Transthoracic echocardiography (TTE) revealed the presence of a left atrial mass mimicking myxoma. However, in postoperative findings, it was determined that the mass was actually a hemorrhagic cyst. Eighteen months later, the patient presented with recurrent exertional dyspnea and TTE revealed the recurrence of a left atrial mass. Computed tomography showed that the mass extended into the right atrium, inferior vena cava, and coronary sinus. After re-operation, the final histological diagnosis was determined to be an undifferentiated pleomorphic sarcoma in the left atrium. LESSONS An intracardiac hemorrhagic cyst was suspected during the operation of a benign-looking LA mass. As such, we recommend that other rare etiologies be considered and more biopsies be performed when possible.

Abstract
BACKGROUND Cytokine genotypes have previously been studied in patients undergoing solid organ transplantation; certain polymorphisms have been implicated in the development of acute rejection (AR) and graft dysfunction (GD). Allograft outcomes determined, in part, by alloimmune responses is mainly mediated by T-cell responses, activated and driven by cytokines. Interleukin-4 (IL-4) is one such cytokine, which exerts its biological effects through binding to the IL-4 receptor (IL-4R) complex on target cells. In the present study, we investigated whether polymorphisms of the IL-4 and/or IL-4R gene were associated with susceptibility to acute AR and GD after kidney transplantation. METHODS We analyzed 2 single nucleotide polymorphism (SNPs) of IL-4 (rs2243250 and rs2070874) and 3 SNPs of IL-4R (rs1801275, rs2107356, and rs1805010) in 344 kidney transplant recipients. These patients included 62 of whom had developed AR and 215 of whom had GD in 1 year after kidney transplantation. RESULTS The AR group included 62 patients (45 men and 17 women). There was a statistically significant difference in the male-to-female ratio and the use of tacrolimus in the AR group. The GD group included 215 patients. Patients who developed GD were more likely to be older and have an underlying cause of end-stage renal disease that was unknown compared with patients who did not have GD, the cause of which was typically known. Among the SNPs examined, 1 of the SNPs in the IL-4R gene (ie, rs1801275) showed a statistical association with AR (co-dominant model, P = .061; dominant model, P = .019; and log-addictive model, P = .029). In addition, 1 of the IL-4R SNPs (ie, rs2107356) was statistically associated with GD (dominant model, P = .034). No significant difference in the IL-4 genotype was observed between the AR/GD and non-AR/non-GD subjects. CONCLUSIONS One IL-4R gene polymorphism (rs1801275) was associated with AR. In addition, a separate IL-4R SNP (rs2107356) was statistically associated with GD after kidney transplantation.

Abstract
BACKGROUND The role of peripheral sigma-1 receptors (Sig-1Rs) in normal nociception and in pathologically induced pain conditions has not been thoroughly investigated. Since there is mounting evidence that Sig-1Rs modulate ischaemia-induced pathological conditions, we investigated the role of Sig-1Rs in ischaemia-induced mechanical allodynia (MA) and addressed their possible interaction with acid-sensing ion channels (ASICs) and P2X receptors at the ischaemic site. METHODS We used a rodent model of hindlimb thrombus-induced ischaemic pain (TIIP) to investigate their role. Western blot was performed to observe changes in Sig-1R expression in peripheral nervous tissues. MA was measured after intraplantar (i.pl.) injections of antagonists for the Sig-1, ASIC and P2X receptors in TIIP rats or agonists of each receptor in naïve rats. RESULTS Sig-1R expression significantly increased in skin, sciatic nerve and dorsal root ganglia at 3 days post-TIIP surgery. I.pl. injections of the Sig-1R antagonist, BD-1047 on post-operative days 0-3 significantly attenuated the development of MA during the induction phase, but had no effect on MA when given during the maintenance phase (days 3-6 post-surgery). BD-1047 synergistically increased amiloride (an ASICs blocker)- and TNP-ATP (a P2X antagonist)-induced analgesic effects in TIIP rats. In naïve rats, i.pl. injection of Sig-1R agonist PRE-084 alone did not produce MA; but it did induce MA when co-administered with either an acidic pH solution or a sub-effective dose of αβmeATP. CONCLUSION Peripheral Sig-1Rs contribute to the induction of ischaemia-induced MA via facilitation of ASICs and P2X receptors. Thus, peripheral Sig-1Rs represent a novel therapeutic target for the treatment of ischaemic pain.

Abstract
We have successfully synthesized the series of the double-perovskite R2CoMnO6 (R = rare earth: La to Lu) single crystals and have investigated their magnetic properties. The ferromagnetic order of Co(2+)/Mn(4+) spins emerges mainly along the c axis. Upon decreasing the size of rare earth ion, the magnetic transition temperature decreases linearly from 204 K for La2CoMnO6 to 48 K for Lu2CoMnO6, along with the enhancement of monoclinic distortion. The temperature and magnetic-field dependences of magnetization reveal the various magnetic characteristics such as the metamagnetic transition in R = Eu, the isotropic nature of rare earth moment in R = Gd, and the reversal of magnetic anisotropy in R = Tb and Dy. Our results offer comprehensive information for understanding the roles of mixed-valent magnetic ions and rare earth magnetic moments on the magnetic properties.

Abstract
AIM We investigated the prognostic value of preoperative N-terminal pro-brain natriuretic peptide (NT-proBNP) in non-cardiac surgery in elderly patients who showed normal left ventricular function on preoperative echocardiography. METHODS We analyzed 1459 patients aged older than 70 years who had consulted a cardiologist for the evaluation of cardiovascular risk for non-cardiac surgery. Of the 721 patients who simultaneously underwent echocardiography and NT-proBNP assessments, 506 who showed normal left ventricular systolic function were included. The predictive power of NT-proBNP for the risk of major adverse cardiac and cerebrovascular events (MACCE) was evaluated. RESULTS MACCE occurred in 40 (7.9%) of the 506 patients, and the median value of NT-proBNP was higher in patients with complications than in those without (MACCE group: 1700.5 pg/mL vs non MACCE group: 206.35 pg/mL; P < 0.001). The area under the receiver operating characteristic curve was 0.804 (P < 0.001), with an optimal cut-off of 425.3 pg/mL. Multivariate analysis showed that increased NT-proBNP (>425.3 pg/mL; odds ratio 6.381; P < 0.001) was the only independent risk factor for the prediction of MACCE. CONCLUSIONS In elderly patients who showed normal left ventricular systolic function on echocardiography, measurement of preoperative NT-proBNP concentration might be a useful test for predicting the occurrence of MACCE after non-cardiac surgery. Geriatr Gerontol Int 2016; 16: 1109-1116.

Abstract
We describe a patient with an asymptomatic complete unroofed coronary sinus (CS) syndrome associated with the CS stenosis in the absence of a persistent left superior vena cava (SVC) as identified on coronary computed tomography angiography. There was a large defect between the CS and the left atrium (i.e. a large left-to-right shunt), but an unusual combination of the absence of a persistent left SVC (i.e. no risk for brain abscess due to the absence of a right-to-left shunt) and the CS stenosis (i.e. a markedly reduced degree of a left-to-right shunt), resulting in an asymptomatic presentation.

Abstract
OBJECTIVE To compare the performance of the 15-G internally cooled electrode with that of the conventional 17-G internally cooled electrode. METHODS A total of 40 (20 for each electrode) and 20 ablation zones (10 for each electrode) were made in extracted bovine livers and in in vivo porcine livers, respectively. Technical parameters, three dimensions [long-axis diameter (Dl), vertical-axis diameter (Dv) and short-axis diameter (Ds)], volume and the circularity (Ds/Dl) of the ablation zone were compared. RESULTS The total delivered energy was higher in the 15-G group than in the 17-G group in both ex vivo and in vivo studies (8.78 ± 1.06 vs 7.70 ± 0.98 kcal, p = 0.033; 11.20 ± 1.13 vs 8.49 ± 0.35 kcal, p = 0.001, respectively). The three dimensions of the ablation zone had a tendency to be larger in the 15-G group than in the 17-G group in both studies. The ablation volume was larger in the 15-G group than in the 17-G group in both ex vivo and in vivo studies (29.61 ± 7.10 vs 23.86 ± 3.82 cm(3), p = 0.015; 10.26 ± 2.28 vs 7.79 ± 1.68 cm(3), p = 0.028, respectively). The circularity of ablation zone was not significantly different in both the studies. CONCLUSION The size of ablation zone was larger in the 15-G internally cooled electrode than in the 17-G electrode in both ex vivo and in vivo studies. ADVANCES IN KNOWLEDGE Radiofrequency ablation of hepatic tumours using 15-G electrode is useful to create larger ablation zones.

Abstract
BACKGROUND AND PURPOSE Spinal astrocytes have emerged as important mechanistic contributors to the genesis of mechanical allodynia (MA) in neuropathic pain. We recently demonstrated that the spinal sigma non-opioid intracellular receptor 1 (σ1 receptor) modulates p38 MAPK phosphorylation (p-p38), which plays a critical role in the induction of MA in neuropathic rats. However, the histological and physiological relationships among σ1, p-p38 and astrocyte activation is unclear. EXPERIMENTAL APPROACH We investigated: (i) the precise location of σ1 receptors and p-p38 in spinal dorsal horn; (ii) whether the inhibition of σ1 receptors or p38 modulates chronic constriction injury (CCI)-induced astrocyte activation; and (iii) whether this modulation of astrocyte activity is associated with MA development in CCI mice. KEY RESULTS The expression of σ1 receptors was significantly increased in astrocytes on day 3 following CCI surgery. Sustained intrathecal treatment with the σ1 antagonist, BD-1047, attenuated CCI-induced increase in GFAP-immunoreactive astrocytes, and the treatment combined with fluorocitrate, an astrocyte metabolic inhibitor, synergistically reduced the development of MA, but not thermal hyperalgesia. The number of p-p38-ir astrocytes and neurons, but not microglia was significantly increased. Interestingly, intrathecal BD-1047 attenuated the expression of p-p38 selectively in astrocytes but not in neurons. Moreover, intrathecal treatment with a p38 inhibitor attenuated the GFAP expression, and this treatment combined with fluorocitrate synergistically blocked the induction of MA. CONCLUSIONS AND IMPLICATIONS Spinal σ1 receptors are localized in astrocytes and blockade of σ1 receptors inhibits the pathological activation of astrocytes via modulation of p-p38, which ultimately prevents the development of MA in neuropathic mice.

Abstract
SETTING Multicentre study. OBJECTIVE To define the clinical characteristics of patients with tuberculosis (TB) destroyed lung due to past TB. DESIGN We reviewed patients with TB-destroyed lung between May 2005 and June 2011. RESULTS A total of 595 patients from 21 hospitals were enrolled. The mean age was 65.63 ± 0.47 (mean ± standard error); 60.5% were male. The mean number of lobes involved was 2.59 ± 0.05. Pleural thickening was observed in 54.1% of the patients. Mean forced vital capacity (FVC), forced expiratory volume in 1 s (FEV(1)), FEV(1)/FVC, bronchodilator response and number of exacerbations per year were respectively 2.06 ± 0.03 l (61.26% ± 0.79), 1.16 ± 0.02 l (49.05% ± 0.84), 58.03% ± 0.70, 5.70% ± 0.34, and 0.40 ± 0.04. The number of lobes involved was significantly correlated with FVC and FEV(1), and with the number of exacerbations per year. Use of long-acting muscarinic antagonists or long-acting beta-2 agonists plus inhaled corticosteroids resulted in bronchodilatory effects. Multivariable regression analysis showed that age, initial FEV(1) (%) and number of exacerbations during follow-up were independent factors affecting change in FEV(1). CONCLUSION Decreased lung function with exacerbation, and progressive decline of FEV(1) were observed in patients with TB-destroyed lung.

Abstract
Subepithelial lesions (SELs) are occasionally found in the esophagus during upper endoscopy. Sometimes endoscopic resection is needed for accurate diagnosis or in the rare cases of malignant transformation of SELs. In this case series, we evaluated the usefulness of endoscopic submucosal resection with a ligation device (ESMR-L) in esophageal SELs. Twenty-three patients with 25 esophageal SELs that were no larger than 13 mm and were localized within the muscularis mucosae or submucosa were enrolled. ESMR-L was successfully performed in all 25 SELs. The en bloc resection rate was 100% (25/25), and histologically complete resection was achieved in 24 lesions (24/25, 96%). After resection of the lesion by snare, minor immediate bleeding occurred in four cases, but there was no delayed bleeding or perforation.

Abstract
BACKGROUND Although triple rule-out CT angiography (TRO) to simultaneously evaluate acute coronary syndrome (ACS), pulmonary embolism (PE), and acute aortic syndrome (AAS) is increasingly used in many institutions, TRO is inevitably associated with increased radiation exposure due to extended z-axis coverage compared with dedicated coronary CT angiography (DCTA). PURPOSE To determine the frequency of exclusion of findings of AAS, PE, and significant incidental non-cardiac pathology that may be the cause of acute chest pain when using a restricted DCTA field of view (FOV). MATERIAL AND METHODS We retrospectively reviewed CT images and charts of 103 patients with acute PE and 50 patients with AAS. Either non-ECG gated dedicated pulmonary or aortic CT angiography was performed using 16- or 64-slice multidetector CT (MDCT). We analyzed the incidence of isolated PE, AAS, or significant non-cardiac pathology outside of DCTA FOV (i.e. from tracheal carina to the base of heart). RESULTS There were two cases of isolated PE (2/103, 1.9%) excluded from the FOV of DCTA. One case of PE was isolated to the subsegmental pulmonary artery in the posterior segment of the right upper lobe. In the second case, pulmonary embolism in the left main pulmonary artery was located out of the FOV of DCTA because the left main pulmonary artery was retracted upwardly by fibrotic scar in the left upper lobe due to prior tuberculosis. There was no case of AAS and significant non-cardiac pathology excluded from the FOV of DCTA. AAS (n = 50) consisted of penetrating atherosclerotic ulcer (n = 7), intramural hematoma (n = 5) and aortic dissection (n = 38). CONCLUSION As isolated PE, AAS, and significant non-cardiac pathology outside of the DCTA FOV rarely occur, DCTA may replace TRO in the evaluation of patients with non-specific acute chest pain and a low pre-test probability of PE or aortic dissection.

Abstract
This article presents specific examples of delayed diagnosis of acute coronary syndrome, acute aortic dissection, and pulmonary embolism resulting from evaluating patients with nonspecific acute chest pain who did not undergo immediate dedicated coronary CT angiography (CTA) or triple rule-out protocol (TRO). These concrete examples of delayed diagnosis may advance the concept of using cardiac CTA (i.e., dedicated coronary CTA versus TRO) to triage patients with nonspecific acute chest pain. This article also provides an overall understanding of how to choose the most appropriate examination based on the specific clinical situation in the emergency department (i.e., dedicated coronary CTA versus TRO versus dedicated pulmonary or aortic CTA), how to interpret the CTA results, and the pros and cons of biphasic versus triphasic administration of intravenous contrast material during TRO examination. A precise understanding of various cardiac CTA protocols will improve the diagnostic performance of radiologists while minimizing hazards related to radiation exposure and contrast use.

Abstract
Statins are potent inhibitors of hydroxyl-3-methylglutaryl co-enzyme A (HMG-CoA) reductase, and have emerged as potential anti-cancer agents based on preclinical evidence. In particular, compelling evidence suggests that statins have a wide range of immunomodulatory properties. However, little is known about the role of statins in tumour immune tolerance. Tumour immune tolerance involves the production of immunosuppressive molecules, such as interleukin (IL)-10, transforming growth factor (TGF)-beta and indoleamine-2,3-dioxygenase (IDO) by tumours, which induce a regulatory T cell (T(reg)) response. In this study, we investigated the effect of simvastatin on the production of IL-10, TGF-beta and IDO production and the proliferation of T(regs) using several cancer cell lines, and Lewis lung cancer (3LL) cells-inoculated mouse tumour model. Simvastatin treatment resulted in a decrease in the number of cancer cells (3LL, A549 and NCI-H292). The production of the immune regulatory markers IL-10, TGF-beta in 3LL and NCI-H292 cells increased after treatment with simvastatin. The expression of IDO and forkhead box P3 (FoxP3) transcription factor was also increased in the presence of simvastatin. In a murine 3LL model, there were no significant differences in tumour growth rate between untreated and simvastatin-treated mice groups. Therefore, while simvastatin had an anti-proliferative effect, it also exhibited immune tolerance-promoting properties during tumour development. Thus, due to these opposing actions, simvastatin had no net effect on tumour growth.

Abstract
In the present study, the chemical constituents of Artemisia fukudo essential oil (AFE) were investigated using GC-MS. The major constituents were alpha-thujone (48.28%), beta-thujone (12.69%), camphor (6.95%) and caryophyllene (6.01%). We also examined the effects of AFE on the production of nitric oxide (NO), prostaglandin E(2) (PGE(2)), tumour necrosis factor (TNF)-alpha, interleukin (IL)-1beta, and IL-6, in lipopolysaccharide (LPS)-activated RAW 264.7 macrophages. Western blotting and RT-PCR tests indicated that AFE has potent dose-dependent inhibitory effects on pro-inflammatory cytokines and mediators. We investigated the mechanism by which AFE inhibits NO and PGE(2) by examining the level of nuclear factor-kappaB (NF-kappaB) activation within the mitogen-activated protein kinase (MAPK) pathway, which is an inflammation-induced signal pathway in RAW 264.7 cells. AFE inhibited LPS-induced ERK, JNK, and p38 phosphorylation. Furthermore, AFE inhibited the LPS-induced phosphorylation and degradation of Ikappa-B-alpha, which is required for the nuclear translocations of the p50 and p65 NF-kappaB subunits in RAW 264.7 cells. Our results suggest that AFE might exert an anti-inflammatory effect by inhibiting the expression of pro-inflammatory cytokines. Such an effect is mediated by a blocking of NF-kappaB activation which consequently inhibits the generation of inflammatory mediators in RAW264.7 cells. AFE may be useful for treating inflammatory diseases.

Abstract
OBJECTIVES The aim of this study was to assess the incidence, predictors, and outcome of plaque prolapse (PP) after stent implantation in acute myocardial infarction. BACKGROUND The imaging characteristics of PP in patients with acute myocardial infarction are not well known. METHODS Intravascular ultrasound (IVUS) imaging was performed in 310 patients immediately following stenting for their first acute myocardial infarction. Multiple clinical, angiographic and IVUS derived variables were compared among patients with and without intrastent PP. RESULTS The PP was detected in 27% of the 310 lesions examined. Stent length was longer (31 +/- 13 mm vs. 21 +/- 8 mm, p < 0.001), and positive remodeling (48% vs. 32%, p = 0.008), plaque rupture (51% vs. 31%, p = 0.001), and thrombus (40% vs. 21%, p = 0.001) were significantly more common in PP lesions compared with non-PP lesions. The creatine kinase-myocardial band (CK-MB) was significantly greater after stenting in PP lesions compared with non-PP lesions (Delta = +12.3 +/- 32.0 U/l vs. -4.9 +/- 46.1 U/l, p = 0.002). During a 1-month follow-up, the incidence of stent thrombosis was not significantly different between PP and non-PP lesions [2/85 (2.4%) vs. 2/225 (0.9%), p = 0.308]. Multivariate analysis showed that PP (odds ratio [OR]: 7.34, p < 0.001), plaque rupture (OR: 1.95, p = 0.023), and thrombus (OR: 1.84, p = 0.026) were independently associated with post-stenting CK-MB elevation, and stent length (OR: 2.39, p = 0.003), plaque rupture (OR: 1.96, p = 0.015), and positive remodeling (OR: 1.72, p = 0.044) were independently associated with the development of PP. CONCLUSIONS PP occurs in one-fourth of infarct-related arteries after stent implantation. Lesion characteristics such as plaque rupture and positive remodeling, together with longer stent predict PP. Although long-term follow-up is pending, PP is associated with more myonecrosis after stenting in patients with acute myocardial infarction.

Abstract
Hypoplastic coronary artery disease (HCAD) is a rare condition that may lead to myocardial infarction (MI) and sudden death. We discovered HCAD in a young man who developed chest pain after heavy drinking and who was found to have suffered an MI. His ECG showed ST-segment elevation with Q waves in the anterior leads, and echocardiography revealed apical dyskinesia with moderate left ventricular (LV) dysfunction. Coronary angiography showed hypoplasia of the left anterior descending (LAD) artery. 99mTc-tetrofosmin-gated myocardial perfusion scintigraphy showed a large, fixed perfusion defect in the anteroseptal and apical segments. Sixty-four-slice cardiac CT and cardiac MR imaging demonstrated thinning of the apical wall with calcification and delayed enhancement, supporting the diagnosis of long-standing MI. The patient was discharged symptom-free on medication for ischemic heart failure two weeks after admission. Although HCAD is very uncommon, it should be considered in children and young adults who suffer MI or sudden cardiac death.

Abstract
To evaluate the effects of calcium channel blocker (CCB) and angiotensin converting enzyme inhibitor (ACEI) on endothelial function and arterial stiffness in stable angina pectoris (SAP), 87 patients with SAP (57.6+/-10.0 yr, 52 males) were divided into two groups; CCB group (group I: n=44, 57.9+/-9.7 yr, 23 males) vs. CCB plus ACEI group (group II: n=43, 57.2+/-10.5 yr, 29 males). Flow mediated vasodilation (FMD) of the brachial artery, pulse wave velocity (PWV), urinary albumin excretion (UAE), and high sensitivity C-reactive protein (hsCRP) were compared. FMD, PWV, UAE, and hsCRP were not different between the groups at baseline. After 6 months of treatment, FMD were significantly improved in group II (7.5+/-3.7 to 8.8+/-2.7%, p<0.001), but not in group I (7.9+/-2.7 to 8.2+/-2.8%, p=0.535). Brachial-ankle PWV were significantly improved in both groups (1,621.3+/-279.4 to 1,512.1+/-225.0 cm/sec in group I, p<0.001, 1,586.8+/-278.5 to 1,434.5+/-200.5 cm/sec in group II, p<0.001). However, heart-femoral PWV were significantly improved (1,025.7+/-145.1 to 946.2+/-112.2 cm/sec, p<0.001) and UAE were significantly decreased (20.19+/-29.92 to 13.03+/-16.42 mg/g Cr, p=0.019) in group II only. In conclusion, combination therapy with CCB and ACEI improves endothelial function, arterial stiffness, and UAE than CCB mono-therapy more effectively in patients with SAP.
