A fixed-dose combination of a stain and an antihypertensive drug may be useful for the treatment of patients with hypertension and hyperlipidemia. It may also improve patient drug compliance to help control risk factors of cardiovascular disease. This study was designed to evaluate the blood pressure–lowering and cholesterol-lowering effect of a fixed-dose combination of irbesartan-atorvastatin compared with monotherapy by either agent over an 8-week treatment period.
Patients with comorbid hypertension and hypercholesterolemia were screened for this randomized, double-blind, Phase III study. Eligible study patients were randomly assigned to test groups receiving a combination of irbesartan 300 mg and atorvastatin 40 mg or 80 mg (IRB300 + ATO40 and IRB300 + ATO80). Comparator groups comprised monotherapy groups with irbesartan 300 mg (IRB300) or atorvastatin 40 mg (ATO40) or atorvastatin 80 mg (ATO80), or placebo. Patients who were eligible at screening were subjected to a 4- to 6-week washout period before commencing 8 weeks of therapy per their assigned group. The primary efficacy end points were percent change in LDL-C and sitting diastolic blood pressure (DBP) levels from baseline to end of therapy. Tolerability profiles of combination therapy were compared with other groups.
A total of 733 patients with comorbid hypertension and hypercholesterolemia were screened for this study; 230 eligible patients were randomized to treatment. The mean age of patients was 58.9 (8.5) years, and their mean body mass index was 25.8 (3.2) kg/m2. More than two thirds (70.9%) of the study patients were male. Mean LDL-C and sitting DBP levels at baseline were 149.54 (29.19) mg/dL and 92.32 (6.03) mm Hg, respectively. Percent reductions in LDL-C after 8 weeks were 46.74% (2.06%) in the IRB300 + ATO40 group and 48.98% (2.12%) in the IRB300 + ATO80 group; these values were 47.13% (3.21%) and 48.30% (2.98%) in the ATO40 and ATO80 comparator groups. Similarly, a reduction in sitting DBP after 8 weeks was –8.50 (1.06) mm Hg in the IRB300 + ATO40 group and 10.66 (1.08) mm Hg in the IRB300 + ATO80 group compared with 8.40 (1.65) mm Hg in the IRB300 group. The incidence rate for treatment-emergent adverse events was 22.27% and was similar between the monotherapy and combination groups.
A once-daily combination product of irbesartan and atorvastatin provided an effective, safe, and more compliable treatment for patients with coexisting hypertension and hyperlipidemia. ClinicalTrials.gov identifier: NCT01442987.

2,3,7,8-Tetrachlorodibenzo-p-dioxin in breast milk increases autistic traits of 3-year-old children in Vietnam
2014
Dioxin levels in the breast milk of mothers residing near a contaminated former airbase in Vietnam remain much higher than in unsprayed areas, suggesting high perinatal dioxin exposure for their infants. The present study investigated the association of perinatal dioxin exposure with autistic traits in 153 3-year-old children living in a contaminated area in Vietnam. The children were followed up from birth using the neurodevelopmental battery Bayley-III. The high-2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) exposed groups (⩾3.5 pg per g fat) showed significantly higher Autism Spectrum Rating Scale (ASRS) scores for both boys and girls than the mild-TCDD exposed groups, without differences in neurodevelopmental scores. In contrast, the high total dioxin-exposed group, indicated by polychlorinated dibenzo-p-dioxins/furans (PCDDs/Fs)—the toxic equivalents (TEQ) levels⩾17.9 pg-TEQ per g fat, had significantly lower neurodevelopmental scores than the mild-exposed group in boys, but there was no difference in the ASRS scores. The present study demonstrates a specific impact of perinatal TCDD on autistic traits in childhood, which is different from the neurotoxicity of total dioxins (PCDDs/Fs).

Although the role of high-intensity lipid-lowering therapy in cardiovascular protection has broadened, concerns still exist about new-onset diabetes mellitus (NODM), especially in vulnerable patients. This study aimed to compare the effect of high-dose (4 mg/d) and usual dose (2 mg/d) pitavastatin on glucose metabolism in patients with hyperlipidemia and impaired fasting glucose (IFG).
In this 12-month study, glucose tolerance and lipid-lowering efficacy of high-dose pitavastatin (4 mg [study group]) was compared with that of usual dose pitavastatin (2 mg [control group]) in patients with hyperlipidemia and IFG. The primary end point was the change of glycosylated hemoglobin (HbA1c) after 24 weeks of treatment. The secondary end points were as follows: (1) NODM within 1 year after treatment, (2) change of lipid parameters, (3) changes of adiponectin, and (4) change of blood glucose and insulin levels.
Of the total 417 patients screened, 313 patients with hypercholesterolemia and IFG were randomly assigned into groups. The mean (SD) change in HbA1c was 0.06% (0.20%) in the study group and 0.03% (0.22%) in the control group (P = 0.27). Within 1 year, 27 patients (12.3%) developed NODM, including 12 (10.6%) of 113 patients in the study group and 15 (14.2%) of 106 in the control group (P = 0.43). The study group had a significantly higher reduction of total cholesterol and LDL-C levels and a higher increase in apolipoprotein A1/apolipoprotein B ratio (0.68 [0.40] vs 0.51 [0.35], P < 0.01).
The high-dose pitavastatin therapy did not aggravate glucose metabolism compared with the usual dose therapy. Moreover, it had a better effect on cholesterol-lowering and apolipoprotein distribution in the patients with hyperlipidemia and IFG.

Despite the usefulness of intravascular ultrasound (IVUS) in percutaneous coronary intervention (PCI), the impact of IVUS guidance on clinical outcomes, particularly for chronic total occlusion (CTO) intervention, has rarely been studied. We sought to investigate the clinical usefulness of IVUS-guided CTO intervention with second-generation drug-eluting stent implantation. From 2007 to 2009, a total of 2,568 patients were enrolled in the Korean-CTO registry and 534 patients with successful implantation of second-generation drug-eluting stents were analyzed. IVUS-guided PCI was performed on 206 patients (39%). Clinical outcomes at 2 years were compared between the IVUS-guidance group and the angiography-guidance group in 201 propensity score–matched pairs. The primary end point was the occurrence of definite or probable stent thrombosis. Clinical characteristics were similar between both groups after matching. At 2 years, the IVUS-guidance group showed significantly less stent thrombosis than the angiography-guidance group (0% vs 3.0%, p = 0.014) and a lesser trend toward myocardial infarction (1.0% vs 4.0%, p = 0.058). Target lesion revascularization (TLR) and major adverse cardiovascular event rates were similar. However, a significant interaction was observed between the use of IVUS and lesion length for predicting the TLR (p = 0.037), suggesting usefulness of IVUS in long-lesion (≥3 cm) relative to short-lesion CTO. In conclusion, although IVUS-guided CTO PCI was not associated with a reduction in overall major adverse cardiovascular events, IVUS guidance appears to be associated with a reduction of stent thrombosis and myocardial infarction compared with angiography-guided CTO PCI. Additionally, TLR occurred less frequently in the IVUS-guidance group, especially for long lesions.

Evaluation of the Efficacy and Safety of the Lercanidipine/Valsartan Combination in Korean Patients With Essential Hypertension Not Adequately Controlled With Lercanidipine Monotherapy: A Randomized, Multicenter, Parallel Design, Phase III Clinical Trial
2015
The objective of this study was to evaluate the efficacy and safety of the lercanidipine/valsartan combination compared with lercanidipine monotherapy in patients with hypertension.
Part 1 of this study was the randomized, multicenter, double-blind, parallel group, Phase III, 8-week clinical trial to compare superiority of lercanidipine 10 mg/valsartan 80 mg (L10/V80) and lercanidipine 10 mg/valsartan 160 mg (L10/V160) combinations with lercanidipine 10 mg (L10) monotherapy. At screening, hypertensive patients, whose diastolic blood pressure (DBP) was >90 mm Hg after 4 weeks with L10, were randomized to 3 groups of L10, L10/V80, and L10/V160. The primary end point was the change in the mean sitting DBP from baseline (week 0) after 8 weeks of therapy. Patients who were randomly assigned to L10/V160 and whose mean DBP was still ≥ 90 mm Hg in part 1 were enrolled to the up-titration extension study with lercanidipine 20 mg/valsartan 160 mg (L20/V160) (part 2).
Of 772 patients screened, 497 were randomized to 3 groups (166 in the L10 group, 168 in the L10/V80 group, and 163 in the L10/V160 group). Mean (SD) age was 55 (9.9) years, and male patients comprised 69%. The mean (SD) baseline systolic blood pressure (SBP)/DBP were 148.4 (15.1)/94.3 (9.5) mm Hg. No significant differences were found between groups in baseline characteristics except the percentages of previous history of antihypertensive medication. The primary end points, the changes of mean (SD) DBP at week 8 from the baseline were −2.0 (8.8) mm Hg in the L10 group, −6.7 (8.5) mm Hg in L10/V80 group, and −8.1 (8.4) mm Hg in L10/V160 group. The adjusted mean difference between the combination groups and the L10 monotherapy group was −4.6 mm Hg (95% CI, −6.5 to −2.6; P < 0.001) in the L10/V80 group and −5.9 mm Hg (95% CI, −7.9 to −4.0, P < 0.001) in the L10/V160 group, which had significantly greater efficacy in BP lowering. A total of 74 patients were enrolled in the part 2 extension study. Changes of mean (SD) DBP and SBP from week 8 to week 12 and week 16 were −5.6 (7.9)/−8.0 (12.0) mm Hg and −5.5 (7.0)/−8.5 (11.3) mm Hg, respectively. For evaluation of the safety profile, the frequencies of adverse events between groups were also not significantly different. The most frequently reported adverse events were headache (6 cases, 20.7%) in the L10 group, dizziness (8 cases, 16.3%) in L10/V80 group, and nasopharyngitis (3 cases, 9.4%) in L10/V160 group, and the incidences of adverse events were not different between groups.
Treatment of L10/V80 or L10/V160 combination therapy resulted in significantly greater BP lowering compared with L10 monotherapy. Moreover, the L20/V160 high dose combination had additional BP lowering effect compared with nonresponders with the L10/V160 combination. ClinicalTrials.gov: NCT01928628.

Dyslipidemia is an important risk factor for cardiovascular disease (CVD). Statins are known to effectively reduce not only low-density lipoprotein cholesterol (LDL-C) level but also death and nonfatal myocardial infarction due to coronary heart disease. The risk for CVD from atherogenic dyslipidemia persists when elevated triglyceride (TG) and reduced high-density lipoprotein cholesterol (HDL-C) levels are not controlled with statin therapy. Therefore, statin/fenofibrate combination therapy is more effective in reducing CVD risk. Here, we assessed the efficacy and tolerability of pitavastatin/fenofibrate combination therapy in patients with mixed dyslipidemia and a high risk for CVD.
This multicenter, randomized, double-blind, parallel-group, therapeutic-confirmatory clinical trial evaluated the efficacy and tolerability of fixed-dose combination therapy with pitavastatin/fenofibrate 2/160 mg in Korean patients with a high risk for CVD and a controlled LDL-C level (<100 mg/dL) and a TG level of 150–500 mg/dL after a run-in period with pitavastatin 2 mg alone. In the 8-week main study, 347 eligible patients were randomly assigned to receive pitavastatin 2 mg with or without fenofibrate 160 mg after a run-in period. In the extension study, patients with controlled LDL-C and non–HDL-C (<130 mg/dL) levels were included after the completion of the main study. All participants in the extension study received the pitavastatin/fenofibrate combination therapy for 16 weeks for the assessment of the tolerability of long-term treatment.
The difference in the mean percentage change in non–HDL-C from baseline to week 8 between the combination therapy and monotherapy groups was −12.45% (95% CI, −17.18 to −7.72), and the combination therapy was associated with a greater reduction in non-HDL-C. The changes in lipid profile, including apolipoproteins, fibrinogen, and high-sensitivity C-reactive protein from baseline to weeks 4 and 8 were statistically significant with combination therapy compared to monotherapy at all time points. Furthermore, the rates of achievement of non–HDL-C and apolipoprotein B targets at week 8 in the combination therapy and monotherapy groups were 88.30% versus 77.98% (P = 0.0110) and 78.94% versus 68.45% (P = 0.0021), respectively. The combination therapy was well tolerated, with a safety profile similar to that of statin monotherapy.
In these Korean patients with mixed dyslipidemia and a high risk for CVD, combination therapy with pitavastatin/fenofibrate was associated with a greater reduction in non–HDL-C compared with that with pitavastatin monotherapy, and a significantly improvement in other lipid levels. Moreover, the combination therapy was well tolerated, with a safety profile similar to that of statin monotherapy. Therefore, pitavastatin/fenofibrate combination therapy could be effective and well tolerated in patients with mixed dyslipidemia. ClinicalTrials.gov identifier: NCT03618797.
•Lipid profiles except LDL-C cannot be controlled properly at all times with statins.•Combination therapy of pitavastatin/fenofibrate reduces non-HDL-C more effectively.•Combination therapy of pitavastatin/fenofibrate improves other lipid profiles.•Combination therapy was well tolerated compared with monotherapy under the conditions of this study.

Percutaneous coronary intervention (PCI) has been developed by drug-eluting stent (DES), but stent implantation has brought the issue of stent thrombosis and optimal antiplatelet therapy. Guidelines recommend at least 6- to 12 months of dual antiplatelet therapy (DAPT) with aspirin and a P2Y12 receptor inhibitor such as clopidogrel. Beyond DAPT after PCI with DES, however, there has been still a debate for antiplatelet regimen. Therefore, we report on the upcoming HOST-EXAM trial (NCT02044250), which will evaluate the efficacy and safety of aspirin and clopidogrel monotherapies beyond DAPT after DES implantation.
The HOST-EXAM is a prospective, randomized, open-label, multicenter, comparative effectiveness trial, to compare between clopidogrel (75 mg once daily) and aspirin (100 mg once daily) as long-term antiplatelet agents. A total of 5,530 patients with no clinical events during combined antiplatelet therapy for 12±6 months after index PCI will be screened, enrolled, and randomized to either group (1:1 ratio) receiving antiplatelet monotherapy for 2 years. The primary endpoint will be the rate of clinical events defined as a composite of all-cause death, nonfatal myocardial infarction, stroke, readmission due to acute coronary syndrome, or major bleeding at 24 months after randomization.
The HOST-EXAM will be the first large-scale randomized controlled study to directly compare the efficacy and safety of long-term antiplatelet monotherapy beyond DAPT after DES implantation. This study will provide clinical evidence to establish optimal regimen for long-term antiplatelet therapy after DES implantation.

Impact of Percutaneous Coronary Intervention for Chronic Total Occlusion in Non–Infarct-Related Arteries in Patients With Acute Myocardial Infarction (from the COREA-AMI Registry)
2016
Chronic total occlusion (CTO) in a non–infarct-related artery (IRA) is an independent predictor of clinical outcomes in patients with acute myocardial infarction (AMI). This study evaluated the impact of successful percutaneous coronary intervention (PCI) for CTO of a non-IRA on the long-term clinical outcomes in patients with AMI. A total of 4,748 patients with AMI were consecutively enrolled in the Convergent Registry of Catholic and Chonnam University for AMI registry from January 2004 to December 2009. We enrolled 324 patients with CTO in a non-IRA. To adjust for baseline differences, propensity matching (96 matched pairs) was used to compare successful PCI and occluded CTO for the treatment of CTO in non-IRA. The primary clinical end points were all-cause mortality and a composite of the major adverse cardiac events, including cardiac death, MI, stroke, and any revascularization during the 5-year follow-up. Patients who received successful PCI for CTO of non-IRA had lower rates of all-cause mortality (16.7% vs 32.3%, hazard ratio 0.459, 95% CI 0.251 to 0.841, p = 0.012) and major adverse cardiac events (21.9% vs 55.2%, hazard ratio 0.311, 95% CI 0.187 to 0.516, p <0.001) compared with occluded CTO group. Subgroup analyses revealed that successful PCI resulted in a better mortality rate in patients with normal renal function compared to patients with chronic kidney disease (p = 0.010). In conclusion, successful PCI for CTO of non-IRA is associated with improved long-term clinical outcomes in patients with AMI.

A new project is underway at the National Ignition Facility with the goal of applying a seed magnetic field to the fusion fuel in an indirect drive hohlraum implosion and quantifying the effect on the hot-spot temperature, shape and neutron yield. Magnetizing fusion fuel is calculated to reduce heat loss from the implosion core by constraining the motion of electrons and fusion-generated alpha particles; this can improve the chances of achieving high-gain fusion in a laboratory plasma. We describe the goals of this project and the significant scientific and technological challenges which must be overcome for this project to succeed.

The most favored strategy for bifurcation lesion is stenting main vessel with provisional side branch (SB) stenting. This study was performed to elucidate predictors for SB failure during this provisional strategy. The study population was patients from 16 centers in Korea who underwent drug-eluting stent implantation for bifurcation lesions with provisional strategy (1,219 patients and 1,236 lesions). On multivariate analysis, the independent predictors for SB jailing after main vessel stenting were SB calcification, large SB reference diameter, severe stenosis of SB, and not taking clopidogrel. Regarding SB compromise, however, the independent predictors were true bifurcation lesion and small SB reference diameter, whereas possible predictors were parent vessel thrombus and parent vessel total occlusion. In addition, SB predilation helps us to get favorable SB outcome. The diameter of SB ostium after main vessel stenting became similar between severe SB lesions treated with predilation and mild SB lesions not treated with predilation. In conclusion, SB calcification, less clopidogrel use, large SB reference diameter, and high SB diameter stenosis are independent predictors for SB jailing, and true bifurcation and small SB reference diameter are independent predictors for SB compromise after main vessel stenting.
