Objective
Mindfulness-based stress reduction (MBSR) is a meditation-based therapy originally recommended for stress management. However, it is currently used to alleviate sleep disturbances. Therefore, this contemporary systematic review aimed to elucidate the clinical effects of MBSR on sleep quality and sleep-related daytime impairment in adults with sleep disturbances, including chronic insomnia disorders.

Design
Systematic review and meta-analysis of randomised controlled trials (RCTs).

Methods
A comprehensive search was conducted using the following databases: Ovid MEDLINE, AMED, Ovidembase, PsycINFO, Cochrane Library, CINAHL, and four domestic databases: KoreaMed, KISS, KMbase and NDSL. The final search update was performed in June 2022. Two researchers independently selected relevant studies, assessed the risk of bias and extracted the data.

Results
Of the 7516 records searched, 20 RCTs and 21 reports were included. In the subgroup analysis, MBSR did not improve objective or subjective sleep quality in chronic insomnia and cancers. However, MBSR versus waitlist control might have been effective in improving subjective sleep quality, but with substantial heterogeneity (standardised mean difference=–0.32; 95% CI: –0.56 to –0.08; I2=71%). In addition, MBSR compared with active control did not improve the sleep-related daytime impairments including depression, anxiety, stress, fatigue and quality of life. The overall risk of bias included in this review was a concern because of performance and detection bias.

Conclusions
MBSR might be ineffective for improving sleep quality in patients with chronic insomnia and cancers. In addition, more than half of the RCTs included in this review had small sample sizes and were vulnerable to performance and detection biases. Therefore, well-designed RCTs with larger sample sizes are required to confirm the clinical effects of MBSR in adults with sleep disturbances.

ROS levels are elevated by specific non-coding, small nucleolar (sno) RNAs encoded within introns of theRpl13agene. We therefore tested the hypothesis that these snoRNAs promote athero, using “snoKO” mice deficient inRpl13asnoRNAs, but not inRpl13aitself. ROS levels assessed by CellROX Orange were 35% lower in snoKO than snoRNA+/+aorta frozen sections (p

Introduction:Greater left ventricular (LV) wall stress is associated with adverse outcomes among patients with prevalent heart failure (HF). Less is known about the association between LV wall stress and risk of incident HF in community dwelling individuals.Methods:Using data from the NHLBI Biologic Specimen and Data Repository Information Coordinating Center, we studied 4,601 participants of the Atherosclerosis Risk in Communities study without prevalent HF who underwent echocardiography at visit 5 (2011-2013). LV end systolic and diastolic wall stress (LVESWS, LVEDWS) were calculated from chamber and wall thickness measures, E/e’ as a surrogate for LV end diastolic pressure, and systemic blood pressure. Incident HF was assessed by cohort surveillance for hospitalized HF through December 31, 2016. The relationship between LVESWS and LVEDWS was examined by Spearman rank correlation. The association between wall stress and risk of incident HF was tested in Cox regression adjusted for demographics, traditional CV risk factors, prevalent CAD and atrial fibrillation, as well as creatinine, NT-proBNP, troponin, triglycerides, C-reactive protein, LV ejection fraction, and LV mass.Results:The cohort was elderly (median age 75 years), predominantly female (58%), with 18% of individuals identifying as black. Median LVESWS and LVEDWS were 48.8 (IQR: 39.3, 60.1) and 18.9 (IQR: 15.8, 22.5) kdynes/cm2, respectively. LVESWS and LVEDWS were modestly correlated (rho = 0.30, p

Introduction:Hypertensive response during stress echocardiography has been predominately studied in a healthy population without many comorbidities, unlike the patients for which these tests are indicated. We performed a retrospective study identifying clinical predictors of hypertensive response to both exercise (EXE) and dobutamine (DSE) stress echo.Methods:Retrospective analysis was performed on all patients who underwent stress echo from January 1, 2015 to February 28, 2017 in a tertiary care academic center. Patient demographics, comorbidities, medications and stress echo parameters were evaluated. Patients were characterized based on stress echo completed as EXE or DSE. The primary outcome was hypertensive response.Results:4670 patients were enrolled: 1238 in the DSE group and 3432 in the EXE group. On multivariable analysis, only resting SBP remained a significant predictor of hypertensive response during DSE (odds ratio (OR) per 20mmHg 3.21, CI 1.57-6.59,p=.001) with an AUC of 0.76. On multivariable analysis, obesity (OR 2.27, CI 1.08-4.8,p=.03), diabetes (OR 3.24, CI 1.22-8.6,p=.02), resting SBP (OR 4.44, CI 2.35-8.38,p

Introduction:The presence of multiple high-risk prognostic features enhances risk-stratification of plaques prone to destabilization and major adverse cardiac events (MACE). Spatial superimposition of high-risk features (concordance) likely amplifies local risk. Local endothelial shear stress (ESS) and plaque structural stress (PSS) metrics predict MACE, but their spatial concordance and their location relative to the minimal lumen area (MLA) is unknown. If the highest-risk plaque area is distant from the MLA, then PCI of the MLA alone will leave high-risk plaque areas untreated.Purpose:To identify the site of high-risk features of low ESS and high PSS heterogeneity (HI) along the course of a plaque in patients who develop MACE, and the site of their spatial concordance relative to the MLA.Methods:We examined ESS, PSS, and PSS HI in 22 non-culprit lesions (NCL) leading to MACE, and 64 randomly selected control NCLs without MACE from the PROSPECT study. ESS was calculated by computational fluid dynamics and PSS by finite element analysis on co-registered lesions. We examined high-risk plaques with empirically-derived (ROC curve) ESS < 1.3 Pa and PSS HI > 0.29 in 16 lesions leading to future MACE, and 11 control lesions without MACE.Results:MACE outcomes were significantly more frequent in plaques with combined low ESS+high PSS HI vs plaques with low ESS alone (72.7% vs 27.3%, p

Circulation, Volume 146, Issue Suppl_1, Page A14699-A14699, November 8, 2022. Introduction and Hypothesis:Endothelial shear stress (ESS) is the tangential force produced by luminal blood flow on arterial endothelium. Both high ESS and low ESS are known to have atherogenic effects, however, it remains poorly understood how these different forces influence coronary atherosclerosis. We evaluated the impact of ESS changes on biochemical and phenotypic difference of coronary atheroma, as assessed by a novel dual-modal optical coherence tomography-fluorescence lifetime imaging (OCT-FLIm)in vivoin beating human coronary arteries.Methods and Results:We constructed a fully-integrated OCT and multispectral FLIm system based on a low-profile dual-modal imaging catheter. High-speed OCT-FLIm could be performed safely in patients undergoing coronary revascularization (Pullback speed: 10-20mm/sec). 3D artery model for computational fluid dynamics was reconstructed by fusion of OCT and angiography. We analyzed spatial associations between ESS and multispectral FLIm information: ch.3(542nm) = fibroatheroma with inflammation; ch.1 (390nm) = loose fibrous tissue (healed plaque). OCT-FLIm visualized coronary microstructure clearly and offered correctly-coregistered biochemical readouts of coronary atherosclerotic plaquein vivoin a label-free manner. Fibroatheromas with increased inflammation activity, as assessed by ch.3 FLIm, were found in low ESS area. On the other hands, high ESS area colocalized with regions with increased ch.1 lifetime, a FLIm signature of loose fibrous tissue (healed plaque). Based on a coregistered ESS-FLIm data, we found a statistically significant negative correlation between ESS and ch.3 lifetime (p >0.001) and a positive correlation between ESS and ch.1 lifetime (p >0.001).Conclusions:Low ESS was associated with lipid and macrophage infiltration whereas high ESS was associated with presence of loose fibrous tissue, a histologic marker of recent plaque disruption leading to rapid plaque progression. Our novel imaging strategy enabling comprehensive evaluation of complex interaction between ESS and biochemical phenotype of plaques is expected to enhance understanding of coronary atherosclerosis biology.

Ischemic heart disease (IHD), a major cause of heart failure, is characterized by metabolic dysfunction and myocardial cell death. Cellular hypoxia activates hypoxia inducible factor 1α (HIF1α) to initiate metabolic, angiogenic, and growth-factor related responses. Under normoxia, HIF1α is degraded by prolyl hydroxylase (PHD) domain-containing proteins via the proteasome. Due to the short half-life of HIF1α (

Introduction:Antidepressants, namely selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs), are efficacious in reducing posttraumatic stress disorder (PTSD) symptoms, but their implications for cardiovascular health are unclear. Although SSRI/SNRI treatment could improve PTSD—thus decreasing cardiovascular risk, antidepressant use has also predicted cardiovascular events. This study examined if antidepressant use was associated with developing ischemic heart disease (IHD) in women veterans with PTSD.Methods:The Veterans Affairs (VA) electronic health record (EHR) database was used to identify women veterans with PTSD who engaged with VA healthcare from 2000-2019. Antidepressant use (documented in the EHR) was categorized as SSRIs, SNRIs, both SSRIs/SNRIs, other, or none (ref). We used Cox regression with time-varying exposure and covariates to estimate effects of antidepressants on risk of incident IHD (angina, MI, CAD). Once a woman was exposed to antidepressants, she was considered exposed until IHD onset or censoring. Age, race, ethnicity, and a range of time-varying risk factors [traditional risk factors (e.g., hypertension), other medical risk factors (e.g., obesity), women-specific risk factors (e.g., preeclampsia), psychiatric risk factors (e.g., depression)], were covariates.Results:The analytic sample comprised 143,324 women without IHD at start of follow-up; mean age was 36.1 years (SD=11.0). Over a median follow-up of 8.6 years, there were 6,633 incident IHD cases. When adjusting for demographics and traditional IHD risk factors, exposure to SNRIs was associated with a 33% greater rate of IHD (95% CI: 1.24-1.43), SSRIs with a 27% greater rate (95% CI: 1.20-1.34), both SSRIs/SNRIs with a 59% greater rate (95% CI: 1.01-2.49), and other antidepressants with a 24% greater rate (95% CI: 1.17-1.31). Associations with SNRIs (HR=1.21, 95% CI: 1.12-1.30), SSRIs (HR=1.15, 95% CI: 1.09-1.22), and other antidepressants (HR=1.19, 95% CI: 1.13-1.26) remained significant in fully adjusted models.Conclusions:Antidepressant use in women veterans with PTSD may exacerbate risk of IHD. Mechanism-focused research and further work in women veterans without PTSD is also needed.

Circulation, Volume 146, Issue Suppl_1, Page A10351-A10351, November 8, 2022. Introduction:The cumulative burden of chronic stress and life events can be measured by Allostatic load (AL), whose high values are related to poorer health outcomes and increased risk of cardiovascular disease (CVD). The primary objective of this study is to analyze the impact of androgen deprivation therapy (ADT) on AL variation in patients upon diagnosis of prostate cancer (PC).Hypothesis:ADT may increase AL variation in prostate cancer patients.Methods:Data were obtained from a Cleveland area integrated health care systems informatics platform. The initial cohort included males ≥18 years diagnosed with PC between 2005 and 2022. AL was calculated using multiple markers representing the cardiovascular, metabolic, and immune systems (Table 1) before diagnosis and monthly during the first year. ADT use was captured based on prescribed medications. A linear-mixed-effects model, adjusted for patient demographics, CVD risk factors, and cancer characteristics, and treatment, was used to study AL monthly variation. The analysis was stratified by Non-Hispanic White (NHW) and Non-Hispanic Black (NHB) race.Results:We analyzed a total of 7,168 PC adenocarcinoma patients (31.7% NHB vs 68.3% NHW), of which 20.9% received ADT. NHBs had higher AL pre-PC diagnosis than NHWs (p=0.001). AL monthly variation was 0.15 (±0.02) higher in all PC patients on ADT (p

Circulation, Volume 146, Issue Suppl_1, Page A10038-A10038, November 8, 2022. Introduction:Low endothelial shear stress (ESS) is a pro-atherogenic stimulus associated with coronary plaque development, while high plaque structural stress (PSS) and its heterogeneity is associated with plaque destabilization. Previous studies showed that combining ESS and PSS additively predicts plaque progression, but no studies have determined their ability to predict major adverse cardiovascular events (MACE). We examined whether combining ESS and PSS improves MACE prediction in patients with acute coronary syndrome.Methods:We examined baseline ESS, ESS gradient, PSS, and PSS heterogeneity index (HI) in 22 non-culprit lesions (NCL) leading to future MACE, and 64 randomly selected control NCLs without MACE from the PROSPECT (Providing Regional Observations to Study Predictors of Events in the Coronary Tree) study. ESS was calculated by computational fluid dynamics and PSS by finite element analysis on co-registered lesions.Results:86 lesions (55 thin-cap and 31 thick-cap fibroatheromas) were analyzed from 67 patients. Lesions that caused future MACE showed baseline higher PSS HI (0.32 vs. 0.24, p

Circulation, Volume 146, Issue Suppl_1, Page A14496-A14496, November 8, 2022. Introduction:Diet induced obese (DIO) mice display increased inducible atrial fibrillation (AF) and an overall increase in reactive oxygen species (ROS) production. NADPH oxidase 2 (NOX2), a major source of cytosolic ROS production in human atria, has been implicated in AF independent of obesity and is significantly increased in the atria of DIO mice. Although treatment with MitoTEMPO, a mitochondrial specific antioxidant reduced AF burden in DIO mice, the actual role of NOX2 in increasing ROS production and atrial remodeling in the context of obesity-induced AF remains unclear.Hypothesis:To test the hypothesis that increased NOX2 modulates atrial remodeling in obesity-induced AF, we used control mice, DIO andNox2-KO mice fed with a 60% HFD for 10 weeks (DIO-KO) and DIO mice treated with a NOX2 blocker, apocynin (DIO-Apocynin).Methods:Trans-esophageal rapid (TE) pacing was used to look at the AF phenotype. Cellular electrophysiology (EP), Western blotting, whole-cell patch clamping were performed to study ion channel remodeling and ROS production.Results:All three DIO mouse groups displayed significantly greater body weight compared to their respective controls (Figure A) After TE pacing, DIO-Apocynin mice displayed 28.26 ± 25.40 s and DIO-KO mice displayed 17.43 ± 31.80 s compared to 167.3 ± 168.9 s in DIO mice (Figure B). NOX2 inhibition reversed obesity-induced ion channel remodeling of potassium channels such asKCNQ1andKCNE1encoding for the IKs current andKCNA5encoding for the IKur current and also reduced mediators of oxidative stress. (Figure C-M) Lastly, voltage clamp in DIO-KO mice showed that NOX2 inhibition reverses obesity-induced IK current increase. (Figure N-O)Conclusions:Thus, these results prove that antioxidant therapy targeting Nox2 abrogated ion channel remodeling and reversed the obesity-induced AF burden. Our findings show the importance of targeting specific antioxidant pathways to manage the AF in patients with obesity.

Introduction and Hypothesis:Arterial healing following stent implantation involves a series of biological reactions such as thrombosis, inflammation, neointimal regeneration. Clinical evidences have shown favorable arterial healing after thin-strut stents, however, there has been a lack ofin vivoimaging evidence on how strut thickness affect vascular healing process. We evaluated local endothelial shear stress (ESS) and healing response of a thin-strut bioresorbable scaffold (BRS, 100μm) compared to first-generation 157μm-thickness ABSORB.Methods and Results:BRS and ABSORB were simultaneously implanted in left coronary arteries of the same pigs (n=7). Detailed scaffolded-artery 3D model was reconstructed based on OCT and angiography. Scaffold-related inflammation response was serially assessed by dual-modal OCT-near-infrared fluorescence (OCT-NIRF) molecular imaging using macrophage-mannose receptor-Cy7 as an inflammation-targeting agent. On ESS analysis, regions with athero-prone low ESS were significantly greater in thick-ABSORB compared to BRS. Dual-modal OCT-NIRF imaging visualized arterial inflammation activity at peri-strut regionsin vivo(Figure). Based on coregistered ESS-NIRF data, we found a significant inverse correlation was found between ESS and NIRF activity (p

Circulation, Volume 146, Issue Suppl_1, Page A12919-A12919, November 8, 2022. Introduction:The SARS-CoV-2 virus has potential to cause acute and long-term cardiac effects. The vaccines were developed to prevent severe illness, but there are concerns about vaccine related side effects. Specific to the heart there have been case reports of mRNA vaccine related cardiomyopathies, particularly myocarditis. We present a case of a patient with presumptive stress induced cardiomyopathy in the setting of recent Covid-19 mRNA vaccination.Case Presentation:A 93-year-old female with a past medical history of hypertension presented with worsening shortness of breath and bilateral lower extremity edema. She received her second dose of the Covid-19 mRNA vaccine five days prior to presentation. She had no history of heart disease, was a nonsmoker, and denied alcohol or drug use. In the ED she was noted to be fluid-overloaded, and her CT chest showed minimal coronary calcification and bilateral pleural effusions. She was admitted for heart failure exacerbation and started on IV furosemide. Her transthoracic echocardiogram showed an ejection fraction of 40-45%. The pattern of left ventricular dysfunction was consistent with stress induced cardiomyopathy with apical akinesis and basal sparing of the left ventricular wall segments. Cardiology was consulted and recommended management with diuretics and beta blocker. She had a diuresis of 5 liters during her hospitalization. At clinic follow-up, dyspnea had improved, and her peripheral edema had resolved. Repeat echocardiogram showed recovery of left ventricular ejection fraction to 61% by Simpsons biplane technique with no regional wall motion abnormalities. Further cardiac assessment to evaluate for obstructive coronary artery disease and myocarditis was discussed and offered to the patient but was declined due to her positive response to conservative management.Discussion:The precise etiology of stress induced cardiomyopathy is unknown, but it is thought to be secondary to the sudden release of stress hormones. There are isolated reports of stress induced cardiomyopathy associated with Covid-19 vaccination, but the potential mechanism is unclear. An improved understanding of the potential effects of mRNA vaccines may help guide decisions regarding future booster vaccinations.

Circulation, Volume 146, Issue Suppl_1, Page A11502-A11502, November 8, 2022. Background -Mitral valve prolapse (MVP) is a common valvular abnormality found in approximately 2.4% of the population. Whereas the majority of cases are benign, an increasingly recognized sequela of MVP is sudden cardiac death (SCD), but triggers and risk factors for SCD are not well-defined. It is theorized that increased stretch on the papillary muscles due to MVP leads to papillary muscle fibrosis and cellular changes of local conduction properties, increasing the risk of ventricular arrhythmias and SCD.Hypothesis- We hypothesized that patients with MVP and SCD would have increased ventricular arrhythmias and ECG changes compared to MVP controls during exercise stress testing.Methods -The study population was generated from the Duke Epic. Patients were included if they had guideline-based diagnosis of MVP on echocardiogram or cardiac magnetic resonance imaging. Increase in ventricular arrhythmias during exercise was defined as >/= 10 PVCs per minute, multifocal PVCs, or >/= 2 PVCs in a row.Results-A total 2,513 patients with MVP were screened. 18 patients with SCD. Patients with SCD were younger [(47.22 +/- 12.2 ) vs. (58.0 +/- 18.7), p=0.02], more likely to be female (89.9% vs 64%, p=0.04) and had increased rate of bileaflet prolapse (72% vs. 40%, p=0.01) compared to controls. Patients with sudden cardiac death had either dynamic T wave changes or increased ventricular arrhythmias with stress testing versus controls [12/18 (66.7%) vs 17/75 (22.6%), p

Circulation, Volume 146, Issue Suppl_1, Page A12932-A12932, November 8, 2022. Introduction:Exercise Stress Echocardiography (ESE) is recommended as a screening tool for the evaluation of Coronary Artery Disease (CAD) in patients with suspected Radiation-Induced Heart Disease (RIHD). Up to now, studies have only evaluated its association with the extent of CAD.HypothesisCancer survivors treated with chest Radiotherapy (RT) that undergo an ESE and have a +ESE develop more MACE than those who have -ESE.Methods:A retrospective, descriptive, cohort study was conducted. Patients who had chest RT and underwent ESE with Treadmill Bruce Stress Protocol, from 2000 to 2012, at Mayo Clinic Rochester and Mayo Clinic Health System were included. A univariate analysis was performed to characterize the population. An analysis including Kruskal Wallis and Pearson Chi-Squared tests was completed to identify variables associated with + SE (Table 1). Multivariable Cox Model for MACE was conducted and is shown in Table 2. A time-to-event curve using Kaplan-Meier estimates is shown in Figure 1.Results:We identified 113 patients, with a mean age of 67 years and a median follow-up of 15.1 years. Of those, 99% were female, 98% were breast cancer survivors, 59% had HTN, 14% DM, 11% AFib, 2% COPD, and 12% had a history of MI. All the patients received >3000cGy of Photon RT, and 57% were treated with systemic cancer therapies. A +ESE was seen in 20.3% of the patients with no significant difference in METS achieved compared with patients who had a -ESE. COPD, RT dose, and systemic therapies, specifically doxorubicin, were associated with a +ESE. The cumulative incidence of MACE was higher in the group of +ESE (p=0.029). After adjustment for HTN, DM, smoking history, hyperlipidemia, and prior MI, the HR for MACE associated with a +ESE was 1.97 (1.09-3.59).Conclusion:MACE was more frequent in patients with a +ESE who received chest RT and doxorubicin versus -ESE. These results support the usefulness of ESE in cancer survivors after RT as a cardiovascular screening tool.

Circulation, Volume 146, Issue Suppl_1, Page A11734-A11734, November 8, 2022. Introduction:Chest pain is common in patients with Post-acute Sequelae of SARS-CoV-2 (PASC), also known as long COVID, but the mechanism is unknown.Hypothesis:We hypothesized that PASC patients with chest pain have impaired myocardial perfusion reserve (MPR) measured by stress perfusion cardiovascular magnetic resonance (CMR) imaging.Methods:We retrospectively identified the first 30 consecutive patients who underwent clinically ordered adenosine stress perfusion CMR for chest pain persisting >4 weeks after SARS-CoV-2 infection (PASC). Patients with a history of coronary artery disease (CAD) or left ventricular ejection fraction (LVEF) 2 SD below mean MPR for controls.Results:In 30 PASC (67% female, age 43±13) and 13 controls (54% female, age 50±12), with LVEF (61±6% vs 59±8%), native T1 (1001±49 vs 992±57 ms), T2 (49.5±3.7 vs 48.0±3.3 ms), and ECV (24.6±2.9 vs 24.6±2.6%) were similar (p >0.2 for all). Prior pericarditis (n=2) or prior myocarditis (n=3) were infrequent, with no acute disease by CMR. PASC patients had significantly lower global MPR than controls (1.54±0.25 vs. 2.20±0.36, p
