Timing of fractional flow reserve-guided complete revascularization in patients with ST-segment elevation myocardial infarction with multivessel disease: Rationale and design of the OPTION-STEMI trial.

BACKGROUND: Current guidelines recommend complete revascularization (CR) in hemodynamically stable patients with ST-segment elevation myocardial infarction (STEMI) and multivessel coronary artery disease (MVD). With regard to the timing of percutaneous coronary intervention (PCI) for non-infarct-related artery (non-IRA), recent randomized clinical trials have revealed that immediate CR was non-inferior to staged CR. However, the optimal timing of CR remains uncertain. The OPTION-STEMI trial compared immediate CR and in-hospital staged CR guided by fractional flow reserve (FFR) for intermediate stenosis of the non-IRA. METHODS: The OPTION-STEMI is a multicenter, investigator-initiated, prospective, open-label, non-inferiority randomized clinical trial. The study included patients with at least 1 non-IRA lesion with ≥50% stenosis by visual estimation. Patients fulfilling the inclusion criteria were randomized into 2 groups at a 1:1 ratio: immediate CR (i.e., PCI for the non-IRA performed during primary angioplasty) or in-hospital staged CR. In the in-hospital staged CR group, PCI for non-IRA lesions was performed on another day during the index hospitalization. Non-IRA lesions with 50%-69% stenosis by visual estimation were evaluated by FFR, whereas those with ≥70% stenosis was revascularized without FFR. The primary endpoint was the composite of all-cause death, non-fatal myocardial infarction, and all unplanned revascularization at 1 year after randomization. Enrolment began in December 2019 and was completed in January 2024. The follow-up for the primary endpoint will be completed in January 2025, and primary results will be available in the middle of 2025. CONCLUSIONS: The OPTION-STEMI is a multicenter, non-inferiority, randomized trial that evaluated the timing of in-hospital CR with the aid of FFR in patients with STEMI and MVD.

Ethyl Formate Fumigation against Pineapple Mealybug, Dysmicoccus brevipes, a Quarantine Insect Pest of Pineapples.

Pineapple mealybug, Dysmicoccus brevipes (Hemiptera: Pseudococcidae), is a significant pest in pineapple production and a key trade barrier. We explored the potential use of ethyl formate (EF) as a methyl bromide alternative for the postharvest fumigation of D. brevipes in imported pineapples. When treated at 8 °C for 4 h, EF fumigation was effective against D. brevipes with LCt99, the lethal concentration × time product of EF necessary to achieve 99% mortality of D. brevipes nymphs and adults at 64.2 and 134.8 g h/m3, respectively. Sorption trials conducted with 70 g/m3 EF for 4 h at 8 °C using 7.5, 15 and 30% pineapple loading ratios (w/v) indicated that loading ratio lower than 30% is necessary to achieve the LCt99 values required to control D. brevipes. In a scaled up trial using 1 m3 chamber, EF fumigation with 70 g/m3 for 4 h at 8 °C with 20% pineapple loading ratio (w/v) resulted in a complete control of D. brevipes treated. There were no significant differences in hue values, sugar contents, firmness, and weight loss between EF-treated and untreated pineapples. Our results suggest that EF is a promising alternative to methyl bromide fumigation for the postharvest phytosanitary disinfection of D. brevipes in pineapples.

Effect of Angiotensin Receptor Blocker Dose in Myocardial Infarction With Preserved Left Ventricular Systolic Function.

ABSTRACT: There have been few studies of angiotensin receptor blocker (ARB) dose in myocardial infarction (MI) with preserved left ventricular (LV) systolic function. We evaluated the association of ARB dose with clinical outcomes after MI with preserved LV systolic function. We used MI multicenter registry. Six months after discharge, the ARB dose was indexed to the target ARB doses used in randomized clinical trials and grouped as >0%-25% (n = 2333), >25% of the target dose (n = 1204), and no ARB (n = 1263). The primary outcome was the composite of cardiac death or MI. Univariate analysis showed that mortality of those with any ARB dose was lower than those without ARB therapy. After multivariable adjustment, patients receiving >25% of target dose had a similar risk of cardiac death or MI compared with those receiving ≤25% or no ARB [hazard ratio (HR) 1.05, 95% confidence interval (CI) 0.83-1.33; HR 0.94, 95% CI 0.82-1.08, respectively]. Propensity score analysis also demonstrated that patients with >25% dose had no difference in primary endpoint compared with those ≤25% dose or the no ARB group (HR 1.03, 95% CI 0.79-1.33; HR 0.86, 95% CI 0.64-1.14, respectively). The present study demonstrates that patients treated with >25% of target ARB dose do not have better clinical outcomes than those treated with ≤25% of target ARB dose or those with no ARB dose in MI patients with preserved LV systolic function.

Ethyl Formate Fumigation for Control of the Scale Insect Asiacornococcus kaki, a Quarantine Pest on Sweet Persimmon, Diospyros kaki: Efficacy, Phytotoxicity and Safety.

Sweet persimmons are a valuable export commodity. However, the presence of live insects such as Asiacornococcus kaki limits their access to many export markets. Methyl bromide, traditionally used for pest control, is damaging to human health and the environment. Ethyl formate (EF) is a viable alternative; however, its effectiveness against A. kaki on sweet persimmon fruit is unknown. We evaluated the effectiveness of EF fumigation in controlling A. kaki present under the calyx of persimmon fruit. The hatching rate of eggs and the survival rates of nymphs and adults of A. kaki at low temperatures, its LCt50 and LCt99 after EF exposure, and phytotoxic damage caused by EF were evaluated in laboratory-scale and commercial-scale tests. The dose-response tests showed that the EF LCt99 at 5 °C was 9.69, 42.13, and 126.13 g h m-3 for adults, nymphs, and eggs, respectively. Commercial-scale tests demonstrated EF efficacy against all A. kaki stages without causing phytotoxic effects on persimmons, though the eggs of A. kaki were not completely controlled in linear low-density polyethylene (LLDPE)-packaged fruit. This study demonstrated that EF is a potential fumigant for quarantine pretreatment, especially before persimmon fruit is packed with LLDPE film, to control A. kaki infesting sweet persimmon fruit.

Comparison of Methyl Bromide and Ethyl Formate for Fumigation of Snail and Fly Pests of Imported Orchids.

Invasive snails and flies are major pests of imported orchids, controlled by methyl bromide (MB) fumigation in Korea. We compared the efficacy and phytotoxicity of ethyl formate (EF) and MB on four species of imported orchids using juvenile stages of Achatina fulica and third and fourth instars of Lycoriella mali. EF was as effective as MB. The LCt99 values of EF were 68.1 and 73.1 g h/m3 at 15 °C; and those of MB were 95.9 and 78.4 g h/m3 at 15 °C for A. fulica and L. mali, respectively. In the scale-up trials, EF treatment at 35 g/m3 for 4 h at 15 °C resulted in complete control of both pests. MB treatment based on the current treatment guidelines for imported orchids (48 g/m3, 2 h, at >15 °C) resulted in complete control of L. mali but not of A. fulica. Chlorophyll content and hue values of treated orchids were not affected by EF treatment but significantly changed by MB (p-value < 0.05). All four treated species of orchids died within 30 d of MB treatment, while only one species died from EF treatment. Our results suggest that EF is a potential alternative to MB in phytosanitary treatment of imported orchids.

Enhancement strategy for effective vascular regeneration following myocardial infarction through a dual stem cell approach.

Since an impaired coronary blood supply following myocardial infarction (MI) negatively affects heart function, therapeutic neovascularization is considered one of the major therapeutic strategies for cell-based cardiac repair. Here, to more effectively achieve therapeutic neovascularization in ischemic hearts, we developed a dual stem cell approach for effective vascular regeneration by utilizing two distinct types of stem cells, CD31+-endothelial cells derived from human induced pluripotent stem cells (hiPSC-ECs) and engineered human mesenchymal stem cells that continuously secrete stromal derived factor-1α (SDF-eMSCs), to simultaneously promote natal vasculogenesis and angiogenesis, two core mechanisms of neovascularization. To induce more comprehensive vascular regeneration, we intramyocardially injected hiPSC-ECs to produce de novo vessels, possibly via vasculogenesis, and a 3D cardiac patch encapsulating SDF-eMSCs (SDF-eMSC-PA) to enhance angiogenesis through prolonged secretion of paracrine factors, including SDF-1α, was implanted into the epicardium of ischemic hearts. We verified that hiPSC-ECs directly contribute to de novo vessel formation in ischemic hearts, resulting in enhanced cardiac function. In addition, the concomitant implantation of SDF1α-eMSC-PAs substantially improved the survival, retention, and vasculogenic potential of hiPSC-ECs, ultimately achieving more comprehensive neovascularization in the MI hearts. Of note, the newly formed vessels through the dual stem cell approach were significantly larger and more functional than those formed by hiPSC-ECs alone. In conclusion, these results provide compelling evidence that our strategy for effective vascular regeneration can be an effective means to treat ischemic heart disease.

Durable polymer versus biodegradable polymer drug-eluting stents in patients with acute coronary syndrome undergoing complex percutaneous coronary intervention: a post hoc analysis of the HOST-REDUCE-POLYTECH-ACS trial.

BACKGROUND: Comparative data of durable polymer (DP) versus biodegradable polymer (BP) drug-eluting stents (DES) are limited in patients presenting with acute coronary syndrome (ACS) undergoing complex percutaneous coronary intervention (PCI). AIMS: We sought to evaluate the efficacy and safety of DP-DES and BP-DES in ACS patients receiving complex PCI. METHODS: This study was a post hoc analysis of the HOST-REDUCE-POLYTECH-ACS trial. ACS patients were randomly assigned 1:1 to DP-DES or BP-DES in the HOST-REDUCE-POLYTECH-ACS trial. Complex PCI was defined as having at least 1 of the following features: ≥3 stents implanted, ≥3 lesions treated, total stent length ≥60 mm, bifurcation PCI with 2 stents, left main PCI, or heavy calcification. Patient-oriented (POCO, a composite of all-cause death, non-fatal myocardial infarction, and any repeat revascularisation) and device-oriented composite outcomes (DOCO, a composite of cardiac death, target vessel myocardial infarction, or target lesion revascularisation) were evaluated at 12 months. RESULTS: Among 3,301 patients for whom full procedural data were available, 1,140 patients received complex PCI. Complex PCI was associated with higher risks of POCO and DOCO. The risks of POCO were comparable between DP-DES and BP-DES in both the complex (HR 0.87, 95% confidence interval [CI]: 0.57-1.33; p=0.522) and non-complex (HR 0.83, 95% CI: 0.56-1.24; p=0.368; p for interaction=0.884) PCI groups. DOCO was also not significantly different between DP-DES and BP-DES in both the complex (HR 0.74, 95% CI: 0.43-1.27; p=0.278) and non-complex (HR 0.67, 95% CI: 0.38-1.19; p=0.175; p for interaction=0.814) PCI groups. CONCLUSIONS: In ACS patients, DP-DES and BP-DES showed similar clinical outcomes irrespective of PCI complexity.

Simple Tandem Olefin Isomerization/Intramolecular Hydroamination of Alkenyl Amines with Various Allylic Tethers.

A simple and efficient AgOTf-promoted tandem olefin isomerization/intramolecular hydroamination of 1,1-disubstituted alkenyl amines has been developed. This one-pot process represents a facile and attractive route for the synthesis of diverse 2-alkyl-substituted 1,3-X,N-heterocycles through chemo- and regioselective C(sp3)-N bond formation with atom economy. Advantages such as the operationally simple and practical procedure that uses a readily available catalyst under aerobic conditions, good to excellent chemical yields, the high functional group tolerance, the broad substrate scope, and high efficiency and selectivity are noteworthy.

Pd-Catalyzed Regioselective Intramolecular Allylic C-H Amination of 1,1-Disubstituted Alkenyl Amines.

Pd-Catalyzed intramolecular allylic C-H amination of 1,1-disubstituted alkenyl amines with various allylic tethers (X = O, NMs, CH2) was developed. This process allows for the divergent synthesis of 1,3-X,N-heterocycles through a regioselective allylic C-H cleavage and π-allylpalladium formation. Particularly noteworthy is the use of substrates containing a labile allylic moiety and new simple catalytic systems capable of promoting highly chemo- and regioselective allylic C-H amination by overcoming significant challenges.

Prasugrel-based De-Escalation of Dual Antiplatelet Therapy After Percutaneous Coronary Intervention in Patients With STEMI.

BACKGROUND AND OBJECTIVES: De-escalation of dual-antiplatelet therapy through dose reduction of prasugrel improved net adverse clinical events (NACEs) after acute coronary syndrome (ACS), mainly through the reduction of bleeding without an increase in ischemic outcomes. Whether the benefits of de-escalation are sustained in highly thrombotic conditions such as ST-elevation myocardial infarction (STEMI) is unknown. We aimed to assess the efficacy and safety of de-escalation therapy in patients with STEMI or non-ST-segment elevation ACS (NSTE-ACS). METHODS: This is a pre-specified subgroup analysis of the HOST-REDUCE-POLYTECH-ACS trial. ACS patients were randomized to prasugrel de-escalation (5 mg daily) or conventional dose (10 mg daily) at 1-month post-percutaneous coronary intervention. The primary endpoint was a NACE, defined as a composite of all-cause death, non-fatal myocardial infarction, stent thrombosis, clinically driven revascularization, stroke, and bleeding events of grade ≥2 Bleeding Academic Research Consortium (BARC) criteria at 1 year. RESULTS: Among 2,338 patients included in the randomization, 326 patients were diagnosed with STEMI. In patients with NSTE-ACS, the risk of the primary endpoint was significantly reduced with de-escalation (hazard ratio [HR], 0.65; 95% confidence interval [CI], 0.48-0.89; p=0.006 for de-escalation vs. conventional), mainly driven by a reduced bleeding. However, in those with STEMI, there was no difference in the occurrence of the primary outcome (HR, 1.04; 95% CI, 0.48-2.26; p=0.915; p for interaction=0.271). CONCLUSIONS: Prasugrel dose de-escalation reduced the rate of NACE and bleeding, without increasing the rate of ischemic events in NSTE-ACS patients but not in STEMI patients.

Long-Term Beta-Blocker Therapy After Myocardial Infarction Without Heart Failure in the Reperfusion Era-Systemic Review and Meta-analysis.

ABSTRACT: Beta-blockers are recommended as a standard treatment for patients who experience a myocardial infarction (MI). However, the evidence supporting this recommendation is based on the prereperfusion era data. This review aims to evaluate the effectiveness of long-term (≥1 year) beta-blocker therapy in post-MI patients without clinical heart failure (HF) in the reperfusion era. We included observational cohort studies, which compared at least 1 year use of beta-blockers to no beta-blockers in patients with an acute MI, but without HF. The clinical endpoint considered was all-cause mortality, except for cardiovascular death in one study. Five cohort studies and 217,532 patients were included. One study demonstrated a reduction in all-cause mortality with beta-blockers, whereas, in 4 studies, there was no difference in the death rate. The pooled estimate by random effect showed that beta-blocker treatment does not reduce mortality (odds ratio 0.800, 95% confidence interval 0.559-1.145) with high heterogeneity (I2 = 94%). This meta-analysis shows that the use of oral beta-blockers for 1 year or more does not reduce the mortality of MI patients without HF. Large randomized trials need to evaluate beta-blocker discontinuation after an acute MI.

Influence of individual proton pump inhibitors on clinical outcomes in patients receiving clopidogrel following percutaneous coronary intervention.

BACKGROUND: Data are conflicting on whether proton pump inhibitors (PPIs) diminish the efficacy of clopidogrel. We investigated individual PPIs and adverse cardiovascular events in postpercutaneous coronary intervention (PCI) patients on dual antiplatelet therapy with clopidogrel. METHODS: We searched Ovid-MEDLINE, EMBASE, and Cochrane from inception to March 2020 to identify studies that evaluated the efficacy and safety of clopidogrel added PPIs versus clopidogrel only in post-PCI patient. We extracted data from 28 studies for major adverse cardiovascular endpoints (MACE), myocardial infarction (MI), cardiovascular death, and gastrointestinal bleeding. Risk ratios (RR) and hazard ratios (HR) were pooled separately. RESULTS: Data were extracted on 131,412 patients from the 28 studies included. Concomitant use of PPI with clopidogrel was associated with increased risk of MACE (RR 1.30; 95% confidence interval [CI] 1.15-1.48; P < .001) and MI (RR 1.43; 95% CI 1.25-1.64; P < .001). Random-effects meta-analyses with individual PPIs demonstrated an increased risk of MACE in those taking pantoprazole (RR 1.31; 95% CI 1.07-1.61, P = .01) or lansoprazole (RR 1.35; 95% CI 1.19-1.54, P < .0001) compared with patients not on PPIs. Likewise, in adjusted analyses, the pooled HR of adjusted events for MACEs showed that the increased risk of MACEs was similar for 4 classes of PPIs but not for rabeprazole (HR: 1.32; 95% CI 0.69-2.53, P = .40). CONCLUSION: The post-PCI patients on dual antiplatelet therapy with clopidogrel in the PPI group were associated with higher risk of MACE and MI. Although the results for rabeprazole were not robust, it was the only PPI that did not yield a significantly increased risk of MACE.

Gender Differences in the Impact of New-Onset Atrial Fibrillation on Long-Term Risk of Ischemic Stroke after Acute Myocardial Infarction.

BACKGROUND: Atrial fibrillation (AF) has been identified as a major risk factor for mortality after acute coronary syndrome (ACS). However, the long-term risk of ischemic stroke associated with new-onset atrial fibrillation (NOAF) in ACS remains controversial, and its gender-specific association is unknown. METHODS: We analyzed the data of 10,137 ACS survivors included in a multicenter, prospective registry for Korean patients with acute myocardial infarction (AMI) between January 2004 and August 2014. Subjects were categorized into three groups (non-AF vs. NOAF vs. previous AF) based on medical history and electrocardiographic evidence of AF, either at admission or during hospitalization. RESULTS: Among the total study population (72.3% men), 370 patients (3.6%) had NOAF and 130 (1.3%) had previous AF. During a median follow-up of 61 months (interquartile range, 38.8 to 89.3 months), 245 (2.4%) patients (218 (2.3%) non-AF vs. 15 (4.1%) NOAF vs. 12 (9.2%) previous AF, p < 0.001) experienced ischemic stroke. After adjustment for confounding variables, both NOAF (adjusted hazard ratio (HR) 1.87, 95% confidence interval (CI) 1.09-3.24, p = 0.024) and previous AF (adjusted HR 4.00, 95% CI 2.03-7.87, p < 0.001), along with older age, diabetes, current smoker, and previous stroke were independent risk factors of ischemic stroke. In the gender-stratified analysis, men with previous AF but not NOAF had a significantly higher risk of ischemic stroke (adjusted HR 4.14, 95% CI 1.79-9.55, p = 0.001) than those without AF. In women, NOAF (adjusted HR 2.54, 95% CI 1.21-5.35, p = 0.014) as well as previous AF (adjusted HR 3.72, 95% CI 1.16-11.96, p = 0.028) was a strong predictor of ischemic stroke, and the predictive value was comparable to that of previous AF among patients with a CHA2DS2-VASc score ≥ 2. CONCLUSIONS: Both NOAF and previous AF were associated with ischemic stroke after AMI, but the impact of NOAF as a risk factor of ischemic stroke was significant only in women.

P2Y12 inhibitor monotherapy in complex percutaneous coronary intervention: A post-hoc analysis of SMART-CHOICE randomized clinical trial.

BACKGROUND: It remains unclear whether P2Y12 monotherapy, especially clopidogrel, following short-duration dual antiplatelet therapy (DAPT) is associated with favorable outcomes in patients undergoing complex percutaneous coronary intervention (PCI). Therefore, this study analyzed the efficacy and safety of P2Y12 inhibitor monotherapy, mostly clopidogrel (78%), in complex PCI following short-term DAPT. METHODS: The post-hoc analysis of the SMART-CHOICE trial involving 2,993 patients included 498 cases of complex PCIs, defined by at least one of the following features: 3 vessels treated, ≥ 3 stents implanted, ≥ 3 lesions treated, bifurcation with ≥ 2 stents implanted, and a total stent length of ≥ 60 mm. The primary endpoint was major adverse cardiac and cerebrovascular event (MACCE), defined as the composite of all-cause death, myocardial infarction, and stroke. The primary safety endpoint included bleeding, defined as Bleeding Academic Research Consortium (BARC) types 2 to 5. RESULTS: Complex PCI group had a higher risk of MACCE (4.0% vs. 2.3%, hazard ratio [HR] = 1.74, 95% confidence interval [CI]: 1.05-2.89, p = 0.033) and a similar risk of BARC types 2-5 bleeding (2.6% vs. 2.6%, HR = 1.02, 95% CI: 0.56-1.86, p = 0.939) compared with those without complex PCIs. Patients undergoing complex PCIs, followed by P2Y12 inhibitor monotherapy and 12 months of DAPT exhibited similar rates of MACCE (3.8% vs. 4.2%, HR = 0.92, 95% CI: 0.38-2.21, p = 0.853). CONCLUSIONS: P2Y12 inhibitor monotherapy, mostly clopidogrel, following 3 months of DAPT did not increase ischemic events in patients with complex PCIs.

Prognostic Value of Estimated Glomerular Filtration Rate 3-6 Months after Percutaneous Coronary Intervention.

BACKGROUND: The prognostic significance of follow-up (f/u) renal function for patients undergoing percutaneous coronary intervention (PCI) remains unknown. This study sought to investigate the prognostic implications of f/u renal function in patients undergoing PCI. METHODS: A drug-eluting stent registry was used. We divided patients into 4 groups according to the change in the estimated glomerular filtration rate (eGFR) before PCI and 3-6 months after PCI. Patients with normal pre-PCI eGFR and f/u eGFR were assigned to group 1. Those with normal pre-PCI eGFR and abnormal f/u eGFR were assigned to group 2. Patients with abnormal pre-PCI eGFR and normal f/u eGFR were assigned to group 3. Patients with abnormal pre-PCI eGFR and f/u eGFR were allocated into group 4. RESULTS: A total of 4,899 PCI patients were enrolled. The death rate in group 1, 2, 3, and 4 at 3 years was 2, 11, 4, and 9%, respectively. This showed significant differences between groups, except between groups 2 and 4. The prognosis of a group with aggravation from normal renal function was worse than that of a group with recovery from abnormal renal function. A prediction model that combines clinical risk factors and f/u eGFR has more power for predicting clinical outcomes than a combination of clinical risk factors and pre-PCI eGFR. CONCLUSION: Post-PCI eGFR was more accurate for predicting patient outcomes than pre-PCI eGFR.

Ischemic and Bleeding Events Associated with Thrombocytopenia and Thrombocytosis after Percutaneous Coronary Intervention in Patients with Acute Myocardial Infarction.

The early and late ischemic and bleeding clinical outcomes according to baseline platelet count after percutaneous coronary intervention (PCI) in patients with acute myocardial infarction (AMI) remain unclear. Overall, 10,667 patients from the Cardiovascular Risk and identification of potential high-risk population in AMI (COREA-AMI) I and II registries were classified according to the following universal criteria on baseline platelet counts: (1) moderate to severe thrombocytopenia (platelet < 100 K/µL, n = 101), (2) mild thrombocytopenia (platelet = 100~149 K/µL, n = 631), (3) normal reference (platelet = 150~450 K/µL, n = 9832), and (4) thrombocytosis (platelet > 450 K/µL, n = 103). The primary endpoint was the occurrence of major adverse cardiovascular events (MACE). The secondary outcome was Bleeding Academic Research Consortium (BARC) 2, 3, and 5 bleeding. After adjusting for confounders, the moderate to severe thrombocytopenia (HR, 2.03; 95% CI, 1.49-2.78); p < 0.001), mild thrombocytopenia (HR, 1.15; 95% CI, 1.01-1.34; p = 0.045), and thrombocytosis groups (HR, 1.47; 95% CI, 1.07-2.03; p = 0.019) showed higher 5-year MACE rates than the normal reference. In BARC 2, 3, and 5 bleeding outcomes, the bleedings rates were higher than the normal range in the moderate to severe thrombocytopenia (HR, 2.18; 95% CI, 1.36-3.49; p = 0.001) and mild thrombocytopenia (HR, 1.41; 95% CI, 1.12-1.78; p = 0.004) groups. Patients with AMI had higher 5-year MACE rates after PCI if they had lower- or higher-than-normal platelet counts. Thrombocytopenia revealed higher early and late bleeding rates whereas thrombocytosis showed long-term bleeding trends, although these trends were not statistically significant.

Efficacy and Safety of Omega-3 Fatty Acids in Patients Treated with Statins for Residual Hypertriglyceridemia: A Randomized, Double-Blind, Placebo-Controlled Clinical Trial.

BACKGROUND: Cardiovascular risk remains increased despite optimal low density lipoprotein cholesterol (LDL-C) level induced by intensive statin therapy. Therefore, recent guidelines recommend non-high density lipoprotein cholesterol (non-HDL-C) as a secondary target for preventing cardiovascular events. The aim of this study was to assess the efficacy and tolerability of omega-3 fatty acids (OM3-FAs) in combination with atorvastatin compared to atorvastatin alone in patients with mixed dyslipidemia. METHODS: This randomized, double-blind, placebo-controlled, parallel-group, and phase III multicenter study included adults with fasting triglyceride (TG) levels ≥200 and <500 mg/dL and LDL-C levels <110 mg/dL. Eligible subjects were randomized to ATOMEGA (OM3-FAs 4,000 mg plus atorvastatin calcium 20 mg) or atorvastatin 20 mg plus placebo groups. The primary efficacy endpoints were the percent changes in TG and non-HDL-C levels from baseline at the end of treatment. RESULTS: After 8 weeks of treatment, the percent changes from baseline in TG (-29.8% vs. 3.6%, P<0.001) and non-HDL-C (-10.1% vs. 4.9%, P<0.001) levels were significantly greater in the ATOMEGA group (n=97) than in the atorvastatin group (n=103). Moreover, the proportion of total subjects reaching TG target of <200 mg/dL in the ATOMEGA group was significantly higher than that in the atorvastatin group (62.9% vs. 22.3%, P<0.001). The incidence of adverse events did not differ between the two groups. CONCLUSION: The addition of OM3-FAs to atorvastatin improved TG and non-HDL-C levels to a significant extent compared to atorvastatin alone in subjects with residual hypertriglyceridemia.

Predictors of Significant Coronary Artery Disease in Patients with Cerebral Artery Atherosclerosis.

OBJECTIVE: There are few existing data on the status of coronary artery disease (CAD) in patients with atherosclerosis of the cerebral artery detected by brain imaging studies. We aimed to analyze the predictors of asymptomatic angiographically significant CAD detected by simultaneous cerebral and coronary angiography. METHODS: This retrospective cohort study screened data obtained between August 2009 and April 2019; 11,047 patients underwent cerebral angiography for atherosclerotic change (>50% stenosis or aneurysm) seen in brain magnetic resonance angiography (MRA) or computed tomography angiography (CTA) at a single center by endovascular neurosurgeon's decision. Of these, 700 patients including 622 patients who underwent simultaneous coronary and cerebral angiography and 78 patients who underwent coronary angiography within a month were enrolled. We investigated the characteristics and predictors of angiographically significant CAD (>50% stenosis). Furthermore, we also analyzed the major adverse cardiovascular and cerebrovascular events (MACCE), including all-cause death, myocardial infarction, and stroke for 5 years. RESULTS: The frequency of significant CAD was 59% (413/700), the mean age was 68.9 ± 10.3 years, and 60.6% were male. During mean follow-up of 50 months, the MACCE rate of our whole cohort was significantly higher in the CAD group (21.5%) than in the non-CAD group (14.6%; hazard ratio 1.65, 95% CI 1.17-2.33, p value = 0.005). Considering that the embolic stroke is less associated with atherosclerotic change, our predictive model of significant CAD was made without embolic stroke (n = 599). In our multivariate model 2 including univariate <0.1, the independent predictors of significant CAD were male (OR 1.62, 95% CI 1.11-2.35, p = 0.012), diabetes mellitus (OR 1.81, 95% CI 1.22-2.68, p = 0.003), previous stroke (OR 1.63, 95% CI 1.02-2.60, p = 0.039), low ankle-brachial index (ABI; <0.9; OR 3.25, 95% CI 1.21-8.73, p = 0.019), left ventricular ejection fraction (EF) <50% on echocardiography (OR 2.82, 95% CI 1.25-6.35, p = 0.012), troponin I or T positive (OR 2.76, 95% CI 1.69-4.53, p < 0.001), and complex features on cerebral angiography (OR 2.73, 95% CI 1.78-4.19, p < 0.001). CONCLUSIONS: Accurate coronary evaluation by coronary angiography might be considered when patients with atherosclerotic cerebral artery detected on brain MRA or CTA planned cerebral angiography were male or have diabetes mellitus, previous stroke, low ABI (<0.9), left ventricular EF <50% on echocardiography, troponin I or T positivity, and complex features on cerebral angiography.
