Abstract: OBJECTIVES:To develop, demonstrate and evaluate an automated deep learning method for multiple cardiovascular structure segmentation. BACKGROUND:Segmentation of cardiovascular images is resource-intensive. We design an automated deep learning method for the segmentation of multiple structures from Coronary Computed Tomography Angiography (CCTA) images. METHODS:Images from a multicenter registry of patients that underwent clinically-indicated CCTA were used. The proximal ascending and descending aorta (PAA, DA), superior and inferior vena cavae (SVC, IVC), pulmonary artery (PA), coronary sinus (CS), right ventricular wall (RVW) and left atrial wall (LAW) were annotated as ground truth. The U-net-derived deep learning model was trained, validated and tested in a 70:20:10 split. RESULTS:The dataset comprised 206 patients, with 5.130 billion pixels. Mean age was 59.9 ± 9.4 yrs., and was 42.7% female. An overall median Dice score of 0.820 (0.782, 0.843) was achieved. Median Dice scores for PAA, DA, SVC, IVC, PA, CS, RVW and LAW were 0.969 (0.979, 0.988), 0.953 (0.955, 0.983), 0.937 (0.934, 0.965), 0.903 (0.897, 0.948), 0.775 (0.724, 0.925), 0.720 (0.642, 0.809), 0.685 (0.631, 0.761) and 0.625 (0.596, 0.749) respectively. Apart from the CS, there were no significant differences in performance between sexes or age groups. CONCLUSIONS:An automated deep learning model demonstrated segmentation of multiple cardiovascular structures from CCTA images with reasonable overall accuracy when evaluated on a pixel level.

2. Recurrent atherosclerosis complications as a mechanism for stent failure

Author: Ioannis Andreou, Peter H. Stone, Ignatios Ikonomidis, Dimitrios Alexopoulos, and Manel Sabaté

Abstract: Stents are an indispensable tool in the percutaneous treatment of symptomatic coronary artery disease. Yet, stent failure due to restenosis or thrombosis may compromise their clinical benefit, carrying substantial morbidity and mortality. Despite improvements in device design and adjunctive medical treatment, stent failure still occurs during long-term follow-up, suggesting that this may be an issue that persists for many years, perhaps indefinitely. Numerous studies during the last decade have highlighted the previously underappreciated pivotal role of atherosclerosis in stent failure. We review evolving evidence on the role of atherosclerosis in stent restenosis and thrombosis, differentiating between de novo in-stent atherosclerosis development (i.e., neoatherosclerosis) and progression of pre-existing underlying atherosclerosis (i.e., paleoatherosclerosis), a distinction with potentially important clinical implications. We conclude with a concept that provides a unifying pathophysiology for these significant problems in the field of interventional cardiology based on the progression and destabilization of atherosclerosis.

4. LncRNA VINAS regulates atherosclerosis by modulating NF-κB and MAPK signaling

Author: Viorel Simion, Haoyang Zhou, Jacob B. Pierce, Dafeng Yang, Stefan Haemmig, Yevgenia Tesmenitsky, Galina Sukhova, Peter H. Stone, Peter Libby, and Mark W. Feinberg
Subjects: Vascular biology, Medicine
Abstract: Long noncoding RNAs (lncRNAs) play important roles in regulating diverse cellular processes in the vessel wall, including atherosclerosis. RNA-Seq profiling of intimal lesions revealed a lncRNA, VINAS (Vascular INflammation and Atherosclerosis lncRNA Sequence), that is enriched in the aortic intima and regulates vascular inflammation. Aortic intimal expression of VINAS fell with atherosclerotic progression and rose with regression. VINAS knockdown reduced atherosclerotic lesion formation by 55% in LDL receptor–deficient (LDLR–/–) mice, independent of effects on circulating lipids, by decreasing inflammation in the vessel wall. Loss- and gain-of-function studies in vitro demonstrated that VINAS serves as a critical regulator of inflammation by modulating NF-κB and MAPK signaling pathways. VINAS knockdown decreased the expression of key inflammatory markers, such as MCP-1, TNF-α, IL-1β, and COX-2, in endothelial cells (ECs), vascular smooth muscle cells, and bone marrow–derived macrophages. Moreover, VINAS silencing decreased expression of leukocyte adhesion molecules VCAM-1, E-selectin, and ICAM-1 and reduced monocyte adhesion to ECs. DEP domain containing 4 (DEPDC4), an evolutionary conserved human ortholog of VINAS with approximately 74% homology, showed similar regulation in human and pig atherosclerotic specimens. DEPDC4 knockdown replicated antiinflammatory effects of VINAS in human ECs. These findings reveal a potentially novel lncRNA that regulates vascular inflammation, with broad implications for vascular diseases.

Abstract: Background and hypothesisThe recently introduced Bayesian quantile regression (BQR) machine-learning method enables comprehensive analyzing the relationship among complex clinical variables. We analyzed the relationship between multiple cardiovascular (CV) risk factors and different stages of coronary artery disease (CAD) using the BQR model in a vessel-specific manner.MethodsFrom the data of 1,463 patients obtained from the PARADIGM (NCT02803411) registry, we analyzed the lumen diameter stenosis (DS) of the three vessels: left anterior descending (LAD), left circumflex (LCx), and right coronary artery (RCA). Two models for predicting DS and DS changes were developed. Baseline CV risk factors, symptoms, and laboratory test results were used as the inputs. The conditional 10%, 25%, 50%, 75%, and 90% quantile functions of the maximum DS and DS change of the three vessels were estimated using the BQR model.ResultsThe 90th percentiles of the DS of the three vessels and their maximum DS change were 41%-50% and 5.6%-7.3%, respectively. Typical anginal symptoms were associated with the highest quantile (90%) of DS in the LAD; diabetes with higher quantiles (75% and 90%) of DS in the LCx; dyslipidemia with the highest quantile (90%) of DS in the RCA; and shortness of breath showed some association with the LCx and RCA. Interestingly, High-density lipoprotein cholesterol showed a dynamic association along DS change in the per-patient analysis.ConclusionsThis study demonstrates the clinical utility of the BQR model for evaluating the comprehensive relationship between risk factors and baseline-grade CAD and its progression.

Abstract: Aims To investigate the impact of statins on plaque progression according to high-risk coronary atherosclerotic plaque (HRP) features and to identify predictive factors for rapid plaque progression in mild coronary artery disease (CAD) using serial coronary computed tomography angiography (CCTA). Methods and results We analyzed mild stenosis (25–49%) CAD, totaling 1432 lesions from 613 patients (mean age, 62.2 years, 63.9% male) and who underwent serial CCTA at a ≥2 year inter-scan interval using the Progression of AtheRosclerotic PlAque DetermIned by Computed TomoGraphic Angiography Imaging (NCT02803411) registry. The median inter-scan period was 3.5 ± 1.4 years; plaques were quantitatively assessed for annualized percent atheroma volume (PAV) and compositional plaque volume changes according to HRP features, and the rapid plaque progression was defined by the ≥90th percentile annual PAV. In mild stenotic lesions with ≥2 HRPs, statin therapy showed a 37% reduction in annual PAV (0.97 ± 2.02 vs. 1.55 ± 2.22, P = 0.038) with decreased necrotic core volume and increased dense calcium volume compared to non-statin recipient mild lesions. The key factors for rapid plaque progression were ≥2 HRPs [hazard ratio (HR), 1.89; 95% confidence interval (CI), 1.02–3.49; P = 0.042], current smoking (HR, 1.69; 95% CI 1.09–2.57; P = 0.017), and diabetes (HR, 1.55; 95% CI, 1.07–2.22; P = 0.020). Conclusion In mild CAD, statin treatment reduced plaque progression, particularly in lesions with a higher number of HRP features, which was also a strong predictor of rapid plaque progression. Therefore, aggressive statin therapy might be needed even in mild CAD with higher HRPs. Clinical trial registration ClinicalTrials.gov NCT02803411

Abstract: Cardiac ischemia during daily life is associated with an increased risk of adverse outcomes. Mental stress is known to provoke cardiac ischemia and is related to psychological variables. In this multicenter cohort study, we assessed whether psychological characteristics were associated with ischemia in daily life.This study examined patients with clinically stable coronary artery disease (CAD) with documented cardiac ischemia during treadmill exercise (n = 196, mean [standard deviation] age = 62.64 [8.31] years; 13% women). Daily life ischemia (DLI) was assessed by 48-hour ambulatory electrocardiophic monitoring. Psychological characteristics were assessed using validated instruments to identify characteristics associated with ischemia occurring in daily life stress.High scores on anger and hostility were common in this sample of patients with CAD, and DLI was documented in 83 (42%) patients. However, the presence of DLI was associated with lower anger scores (odds ratio [OR] = 2.03; 95% confidence interval [CI] = 1.12-3.69), reduced anger expressiveness (OR = 2.04; 95% CI = 1.10-3.75), and increased ratio of anger control to total anger (OR = 2.33; 95% CI = 1.27-4.17). Increased risk of DLI was also associated with lower hostile attribution (OR = 2.22; 95% CI = 1.21-4.09), hostile affect (OR = 1.92; 95% CI = 1.03-3.58), and aggressive responding (OR = 2.26; 95% CI = 1.25-4.08). We observed weak inverse correlations between DLI episode frequency and anger expressiveness, total anger, and hostility scores. DLI was not associated with depression or anxiety measures. The combination of the constructs low anger expressiveness and low hostile attribution was independently associated with DLI (OR = = 2.59; 95% CI = 1.42-4.72).In clinically stable patients with CAD, the tendency to suppress angry and hostile feelings, particularly openly aggressive behavior, was associated with DLI. These findings warrant a study in larger cohorts, and intervention studies are needed to ascertain whether management strategies that modify these psychological characteristics improve outcomes.

Abstract: BACKGROUND: Among patients with stable coronary disease and moderate or severe ischemia, whether clinical outcomes are better in those who receive an invasive intervention plus medical therapy than in those who receive medical therapy alone is uncertain. METHODS: We randomly assigned 5179 patients with moderate or severe ischemia to an initial invasive strategy (angiography and revascularization when feasible) and medical therapy or to an initial conservative strategy of medical therapy alone and angiography if medical therapy failed. The primary outcome was a composite of death from cardiovascular causes, myocardial infarction, or hospitalization for unstable angina, heart failure, or resuscitated cardiac arrest. A key secondary outcome was death from cardiovascular causes or myocardial infarction. RESULTS: Over a median of 3.2 years, 318 primary outcome events occurred in the invasive-strategy group and 352 occurred in the conservative-strategy group. At 6 months, the cumulative event rate was 5.3% in the invasive-strategy group and 3.4% in the conservative-strategy group (difference, 1.9 percentage points; 95% confidence interval [CI], 0.8 to 3.0); at 5 years, the cumulative event rate was 16.4% and 18.2%, respectively (difference, -1.8 percentage points; 95% CI, -4.7 to 1.0). Results were similar with respect to the key secondary outcome. The incidence of the primary outcome was sensitive to the definition of myocardial infarction; a secondary analysis yielded more procedural myocardial infarctions of uncertain clinical importance. There were 145 deaths in the invasive-strategy group and 144 deaths in the conservative-strategy group (hazard ratio, 1.05; 95% CI, 0.83 to 1.32). CONCLUSIONS: Among patients with stable coronary disease and moderate or severe ischemia, we did not find evidence that an initial invasive strategy, as compared with an initial conservative strategy, reduced the risk of ischemic cardiovascular events or death from any cause over a median of 3.2 years. The trial findings were sensitive to the definition of myocardial infarction that was used.

Abstract: Aims The magnitude of alterations in which coronary arteries remodel and narrow over time is not well understood. We aimed to examine changes in coronary arterial remodelling and luminal narrowing by three-dimensional (3D) metrics from serial coronary computed tomography angiography (CCTA). Methods and results From a multicentre registry of patients with suspected coronary artery disease who underwent clinically indicated serial CCTA (median interscan interval = 3.3 years), we quantitatively measured coronary plaque, vessel, and lumen volumes on both scans. Primary outcome was the per-segment change in coronary vessel and lumen volume from a change in plaque volume, focusing on arterial remodelling. Multivariate generalized estimating equations including statins were calculated comparing associations between groups of baseline percent atheroma volume (PAV) and location within the coronary artery tree. From 1245 patients (mean age 61 ± 9 years, 39% women), a total of 5721 segments were analysed. For each 1.00 mm3 increase in plaque volume, the vessel volume increased by 0.71 mm3 [95% confidence interval (CI) 0.63 to 0.79 mm3, P < 0.001] with a corresponding reduction in lumen volume by 0.29 mm3 (95% CI −0.37 to −0.21 mm3, P < 0.001). Serial 3D arterial remodelling and luminal narrowing was similar in segments with low and high baseline PAV (P ≥ 0.496). No differences were observed between left main and non-left main segments, proximal and distal segments and side branch and non-side branch segments (P ≥ 0.281). Conclusions Over time, atherosclerotic coronary plaque reveals prominent outward arterial remodelling that co-occurs with modest luminal narrowing. These findings provide additional insight into the compensatory mechanisms involved in the progression of coronary atherosclerosis.

Abstract: BACKGROUND The association between the change in vessel inflammation, as quantified by perivascular adipose tissue (PVAT) density, and the progression of coronary atherosclerosis remains to be determined.OBJECTIVES The purpose of this study was to explore the association between the change in PVAT density and the progression of total and compositional plaque volume (PV). METHODS Patients were selected from a prospective multinational registry. Patients who underwent serial coronary computed tomography angiography studies with $2-year intervals and were scanned with the same tube voltage at baseline and follow-up were included. Total and compositional PV and PVAT density at baseline and follow-up were quantitatively analyzed for every lesion. Multivariate linear regression models using cluster analyses were constructed.RESULTS A total of 1,476 lesions were identified from 474 enrolled patients (mean age 61.2 +/- 9.3 years; 65.0% men). The mean PVAT density was-74.1 +/- 11.5 HU, and total PV was 48.1 +/- 83.5 mm3 (19.2 +/- 44.8 mm3 of calcified PV and 28.9 +/- 51.0 mm3 of noncalcified PV). On multivariate analysis (adjusted for clinical risk factors, medication use, change in lipid levels, total PV at baseline, luminal HU attenuation, location of lesions, and tube voltage), the increase in PVAT density was positively associated with the progression of total PV (estimate = 0.275 [95% CI: 0.004-0.545]; P = 0.047), driven by the association with fibrous PV (estimate = 0.245 [95% CI: 0.070-0.420]; P = 0.006). Calcified PV progression was not associated with the increase in PVAT density (P > 0.050). CONCLUSIONS Increase in vessel inflammation represented by PVAT density is independently associated with the progression of the lipid component of coronary atherosclerotic plaques.

Abstract: Background and aims: Clinical atherosclerosis manifestations are different in women compared to men. Since endothelial shear stress (ESS) is known to play a critical role in coronary atherosclerosis development, we investigated differences in anatomical characteristics and endothelial shear stress (ESS)–related plaque growth in human coronary arteries in men compared to women. Methods: 1183 coronary arteries (male/female: 944/239) from the PREDICTION study were studied for differences in artery/plaque and ESS characteristics, and ESS-related plaque progression (6–10 months follow-up) among men and women and after stratification for age. All characteristics were derived from IVUS-based vascular profiling and reported per 3 mm-segments (13,030 3-mm-segments (male/female: 10,465/2,565)). Results: Coronary arteries and plaques were significantly smaller in females compared to males; but no important differences were observed in plaque burden, ESS and rate of plaque progression. Change in plaque burden was inversely related to ESS (p

Abstract: Importance: Distinct plaque locations and vessel geometric features predispose to altered coronary flow hemodynamics. The association between these lesion-level characteristics assessed by coronary computed tomographic angiography (CCTA) and risk of future acute coronary syndrome (ACS) is unknown. Objective: To examine whether CCTA-derived adverse geometric characteristics (AGCs) of coronary lesions describing location and vessel geometry add to plaque morphology and burden for identifying culprit lesion precursors associated with future ACS. Design, Setting, and Participants: This substudy of ICONIC (Incident Coronary Syndromes Identified by Computed Tomography), a multicenter nested case-control cohort study, included patients with ACS and a culprit lesion precursor identified on baseline CCTA (n = 116) and propensity score-matched non-ACS controls (n = 116). Data were collected from July 20, 2012, to April 30, 2017, and analyzed from October 1, 2020, to October 31, 2021. Exposures: Coronary lesions were evaluated for the following 3 AGCs: (1) distance from the coronary ostium to lesion; (2) location at vessel bifurcations; and (3) vessel tortuosity, defined as the presence of 1 bend of greater than 90° or 3 curves of 45° to 90° using a 3-point angle within the lesion. Main Outcomes and Measures: Association between lesion-level AGCs and risk of future ACS-causing culprit lesions. Results: Of 548 lesions, 116 culprit lesion precursors were identified in 116 patients (80 [69.0%] men; mean [SD], age 62.7 [11.5] years). Compared with nonculprit lesions, culprit lesion precursors had a shorter distance from the ostium (median, 35.1 [IQR, 23.6-48.4] mm vs 44.5 [IQR, 28.2-70.8] mm), more frequently localized to bifurcations (85 [73.3%] vs 168 [38.9%]), and had more tortuous vessel segments (5 [4.3%] vs 6 [1.4%]; all P

Abstract: Introduction: Risk-stratification of individual coronary plaques is an important goal to detect high-risk plaques likely to progress/destabilize, which could inform preemptive intervention to prevent adverse cardiac events. IVUS imaging, the current gold standard to assess plaque risk, has shown that biomechanical variables, particularly local ESS, contributes critical synergistic prognostic insight when combined with anatomic high-risk plaque features. Non-invasive risk assessment of coronary plaques with CCTA would be invaluable to enable broad population risk screening, but it is unknown whether CCTA, which has less spatial resolution than IVUS, can adequately measure the critical local biomechanical and anatomic variables. Aim: To compare the accuracy of ESS computation of local ESS metrics by non-invasive CCTA vs invasive IVUS imaging. Methods: We analyzed 30 arteries (22 LAD, 4 LCx,4 RCA) from 30 patients selected from a registry of patients who underwent both IVUS and CCTA of the same artery for suspected CAD. CCTA images were acquired using a CCTA with either 64 or 256 detector rows. We segmented lumen, vessel, and plaque areas with both IVUS (manual segmentation) and CCTA (AI based software; Cleerly Inc, NY). Co-registration of IVUS and CCTA Images was performed using fiduciary anatomic landmarks. Images from IVUS and CCTA were used to generate a 3-D arterial reconstruction, and local ESS distribution was assessed by computational fluid dynamics and reported in consecutive 3-mm segments. Results: Table Conclusion: Compared to IVUS values, 256-slice is more accurate than 64-slice CCTA to measure lumen and vessel areas, but computation of detailed local ESS (average, low and high) is similar by both CCTA methods. Local ESS evaluation using non-invasive CCTA is feasible and comparable to invasive gold standard IVUS and is suitable to characterize the local flow patterns that play an important role in plaque development, progression, and destabilization

Subjects: Physiology (medical), Cardiology and Cardiovascular Medicine
Abstract: Introduction: The role of endothelial shear stress (ESS) in the development of coronary plaque erosion is unknown. High ESS gradient (ESSG) has been hypothesized to promote plaque erosion, but no studies have included matched control stable plaques with the same minimal and reference lumen area (MLA, RLA, respectively). No studies examined the location of plaque erosion (proximal vs distal to MLA of the culprit plaque) related to the max magnitude of upslope vs downslope of the lumen obstruction. Aims: (1) to compare ESSG between plaques with erosion and similar control plaques that remained stable; (2) among erosion plaques, to study the effect of max slope steepness (Δ lumen area/frame) up- and down-stream from the culprit plaque MLA on thrombus location. Methods: We studied 46 patients from TOTAL and COMPLETE trials who underwent angiography and OCT imaging: 46 arteries: 27 LAD, 6 LCX, 13 RCA. Plaques were divided into Plaque Erosion (n=24) with OCT features of erosion before PCI (17 definite, 7 probable erosion) and matched coronary plaques from separate control patients (n=22) without plaque disruption. Orthogonal angiographic views were used to generate a 3-D arterial reconstruction, and angio centerline was combined with OCT centerline. Local ESS distribution was assessed by computational fluid dynamics and reported in consecutive 3-mm segments. Among the plaque erosions, we calculated the up- and down-slope (Δ lumen area/frame) of lumen obstruction for each culprit plaque. Results: See Table Conclusion: In plaques with similarly severe obstruction, plaque erosion is associated with higher max ESS and max ESSG vs plaques that remain stable. Proximal plaque erosion/thrombus is associated with steeper plaque upslope vs downslope, and distal plaque erosion/thrombus is associated with steeper plaque downslope vs upslope. Absolute ESSG is higher in downslope vs upslope erosions. These features may help prognosticate individual plaques at risk for future erosion.

Abstract: BACKGROUND AND AIMS:Different methodologies to report whole-heart atherosclerotic plaque on coronary computed tomography angiography (CCTA) have been utilized. We examined which of the three commonly used plaque burden definitions was least affected by differences in body surface area (BSA) and sex. METHODS:The PARADIGM study includes symptomatic patients with suspected coronary atherosclerosis who underwent serial CCTA >2 years apart. Coronary lumen, vessel, and plaque were quantified from the coronary tree on a 0.5mm cross-sectional basis by a core-lab, and summed to per-patient. Three quantitative methods of plaque burden were employed: (1) total plaque volume (PV) in mm3, (2) percent atheroma volume (PAV) in % [which equaled: PV/vessel volume * 100%], and (3) normalized total atheroma volume (TAVnorm) in mm3 [which equaled: PV/vessel length * mean population vessel length]. Only data from the baseline CCTA were used. PV, PAV, and TAVnorm were compared between patients in the top quartile of BSA vs the remaining, and between sexes. Associations between vessel volume, BSA, and the three plaque burden methodologies were assessed. RESULTS:The study population comprised 1479 patients (age 60.7±9.3 years, 58.4% male) who underwent CCTA. A total of 17,649 coronary artery segments were evaluated with a median of 12 (IQR 11-13) segments per-patient (from a 16-segment coronary tree). Patients with a large BSA (top quartile), compared with the remaining patients, had a larger PV and TAVnorm, but similar PAV. The relation between larger BSA and larger absolute plaque volume (PV and TAVnorm) was mediated by the coronary vessel volume. Independent from the atherosclerotic cardiovascular disease risk (ASCVD) score, vessel volume correlated with PV (P&nbsp

Abstract: Objectives This study sought to determine if plaque structural stress (PSS) and other plaque stress parameters are increased in plaques that cause future major adverse cardiovascular event(s) (MACE) and if incorporating these parameters improves predictive capability of intravascular ultrasonography (IVUS). Background Less than 10% of coronary plaques identified as high-risk by intravascular imaging result in subsequent MACE. Thus, more specific measurements of plaque vulnerability are required for effective risk stratification. Methods Propensity score matching in the PROSPECT (Providing Regional Observations to Study Predictors of Events in the Coronary Tree) study plaque cohort resulted in 35 nonculprit lesions (NCL) associated with future MACE and 66 matched NCL that remained clinically silent. PSS was calculated by finite element analysis as the mechanical loading within the plaque structure in the periluminal region. Results PSS was increased in the minimal luminal area (MLA) regions of NCL MACE versus no MACE plaques for all plaques (PSS: 112.1 ± 5.5 kPa vs. 90.4 ± 3.3 kPa, respectively; p = 0.001) and virtual histology thin-cap fibroatheromas (VH-TCFAs) (PSS: 119.2 ± 6.6 kPa vs. 95.8 ± 5.0 kPa, respectively; p = 0.005). However, PSS was heterogeneous over short segments, and PSS heterogeneity index (HI) was markedly greater in NCL MACE than in no-MACE VH-TCFAs (HI: 0.43 ± 0.05 vs. 0.29 ± 0.03, respectively; p = 0.01). Inclusion of PSS in plaque assessment improved the identification of NCLs that led to MACE, including in VH-TCFAs (p = 0.03) and plaques with MLA ≤4 mm2 (p = 0.03). Incorporation of an HI further improved the ability of PSS to identify MACE NCLs in a variety of plaque subtypes including VH-TCFA (p = 0.001) and plaques with MLA ≤4 mm2 (p = 0.002). Conclusions PSS and variations in PSS are increased in the peri-MLA regions of plaques that lead to MACE. Moreover, longitudinal heterogeneity in PSS is markedly increased in MACE plaques, especially VH-TCFAs, potentially predisposing to plaque rupture. Incorporation of PSS and heterogeneity in PSS may improve the ability of IVUS to predict MACE., Central Illustration

Abstract: Thesis: S.B., Massachusetts Institute of Technology, Department of Earth, Atmospheric, and Planetary Sciences, 2006., Cataloged from PDF version of thesis. "February 2006.", Includes bibliographical references (page 35)., A parameter representing circulation due to wind forcing is added to the thermohaline circulation model of Marotzke (1996). The model consists of four boxes and is governed by a system of two differential equations governing the temperature and salinity differences between high latitude ocean and low latitude ocean boxes. The modified model is solved numerically for equilibrium solutions, and then solved analytically by the method of Krasovskiy and Stone (1998). At the maximum strength of wind-forced circulation studied, v = 5 x 10-¹¹ s-¹, a stable thermal mode equilibrium temperature difference of 25 K is calculated. Once v reaches a critical value, which is within the range of physically reasonable values, the stable haline mode equlibrium and unstable thermal mode equilibrium are no longer observed. It is concluded that strong wind-forced circulation suppresses the thermal mode equilibrium, but that more research is necessary to determine the degree to which this effect is present in the real world., by Elise M.

Abstract: This study sought to determine whether indocyanine green (ICG)-enhanced near-infrared fluorescence (NIRF) imaging can illuminate high-risk histologic plaque features of human carotid atherosclerosis, and in coronary atheroma of living swine, using intravascular NIRF-optical coherence tomography (OCT) imaging.New translatable imaging approaches are needed to identify high-risk biological signatures of atheroma. ICG is a U.S. Food and Drug Administration-approved NIRF imaging agent that experimentally targets plaque macrophages and lipid in areas of enhanced endothelial permeability. However, it is unknown whether ICG can target atheroma in patients.Eight patients were enrolled in the BRIGHT-CEA (Indocyanine Green Fluorescence Uptake in Human Carotid Artery Plaque) trial. Five patients were injected intravenously with ICG 99 ± 25 min before clinically indicated carotid endarterectomy. Three saline-injected endarterectomy patients served as control subjects. Excised plaques underwent analysis by intravascular NIRF-OCT, reflectance imaging, microscopy, and histopathology. Next, following ICG intravenous injection, in vivo intracoronary NIRF-OCT and intravascular ultrasound imaged 3 atheroma-bearing coronary arteries of a diabetic, cholesterol-fed swine.ICG was well tolerated; no adverse clinical events occurred up to 30 days post-injection. Multimodal NIRF imaging including intravascular NIRF-OCT revealed that ICG accumulated in all endarterectomy specimens. Plaques from saline-injected control patients exhibited minimal NIRF signal. In the swine experiment, intracoronary NIRF-OCT identified ICG uptake in all intravascular ultrasound-identified plaques in vivo. On detailed microscopic evaluation, ICG localized to plaque areas exhibiting impaired endothelial integrity, including disrupted fibrous caps, and within areas of neovascularization. Within human plaque areas of endothelial abnormality, ICG was spatially related to localized zones of plaque macrophages and lipid, and, notably, intraplaque hemorrhage.This study demonstrates that ICG targets human plaques exhibiting endothelial abnormalities and provides new insights into its targeting mechanisms in clinical and experimental atheroma. Intracoronary NIRF-OCT of ICG may offer a novel, clinically translatable approach to image pathobiological aspects of coronary atherosclerosis.

Abstract: This study sought to determine whether low endothelial shear stress (ESS) adds independent prognostication for future major adverse cardiac events (MACE) in coronary lesions in patients with high-risk acute coronary syndrome (ACS) from the United States and Europe.Low ESS is a proinflammatory, proatherogenic stimulus associated with coronary plaque development, progression, and destabilization in human-like animal models and in humans. Previous natural history studies including baseline ESS characterization investigated low-risk patients.In the PROSPECT (Providing Regional Observations to Study Predictors of Events in the Coronary Tree) study, 697 patients with ACS underwent 3-vessel intracoronary imaging. Independent predictors of MACE attributable to untreated nonculprit (nc) coronary lesions during 3.4-year follow-up were large plaque burden (PB), small minimum lumen area (MLA), and thin-cap fibroatheroma (TCFA) morphology. In this analysis, baseline ESS of nc lesions leading to new MACE (nc-MACE lesions) and randomly selected control nc lesions without MACE (nc-non-MACE lesions) were calculated. A propensity score for ESS was constructed for each lesion, and the relationship between ESS and subsequent nc-MACE was examined.A total of 145 lesions were analyzed in 97 patients: 23 nc-MACE lesions (13 TCFAs, 10 thick-cap fibroatheromas [ThCFAs]), and 122 nc-non-MACE lesions (63 TCFAs, 59 ThCFAs). Low local ESS (1.3 Pa) was strongly associated with subsequent nc-MACE compared with physiological/high ESS (≥1.3 Pa) (23 of 101 [22.8%]) versus (0 of 44 [0%]). In propensity-adjusted Cox regression, low ESS was strongly associated with MACE (hazard ratio: 4.34; 95% confidence interval: 1.89 to 10.00; p 0.001). Categorizing plaques by anatomic risk (high risk: ≥2 high-risk characteristics PB ≥70%, MLA ≤4 mmLocal low ESS provides incremental risk stratification of untreated coronary lesions in high-risk patients, beyond measures of PB, MLA, and morphology.

Abstract: Introduction: Low ESS, a pro-inflammatory stimulus, is an important predictor of coronary plaque development/progression. Whether low ESS adds incremental predictive value for future major adverse cardiac events (MACE) in untreated coronary lesions in high-risk patients with an acute coronary syndrome (ACS) is unknown. Methods: In the PROSPECT study, 697 patients with ACS underwent 3-vessel intracoronary imaging. Independent predictors of non-culprit (nc) lesion MACE from untreated coronary lesions in 3 year followup (f/u) were large plaque burden (PB), small minimum lumen area (MLA), and thin cap fibroatheroma (TCFA) morphology. In the present analysis, all nc-lesions leading to a new MACE in f/u (nc-MACE lesions, n=50) and ~4-fold randomly selected control nc-lesions without f/u MACE (nc-non-MACE lesions) were analyzed. Baseline ESS for each lesion was calculated using computational fluid dynamics. A propensity score for low ESS was determined accounting for PB, MLA, TCFA, artery and location in the artery. Local ESS (lowest ESS in 90 o arc around the artery) was then examined for incremental association with MACE. Results: Imaging was sufficient for analysis in 32 nc-MACE lesions. Two nc-MACE lesions were excluded due to unreliable lesion morphology. Non-fibroatheromas were too few for analysis and excluded. Final dataset included 145 lesions: 13 nc-MACE TCFA, 10 nc-MACE thick cap fibroatheroma (ThCFA), and 122 non-nc-MACE lesions (63 TCFA, 59 ThCFA). Cumulative frequency distribution shows lesions responsible for future nc-MACE frequently exhibited low ESS (Figure). In a propensity-adjusted multivariable model, low ESS was strongly associated with nc-MACE in f/u (odds ratio 0.16 [95% CI 0.06-0.40], p Conclusions: After accounting for large PB, small MLA, TCFA, and lesion location, low local ESS adds significant and substantial incremental predictive value to identify high-risk untreated lesions likely to cause MACE during 3 year followup.

Abstract: Background: The natural history and the role of the atherosclerotic plaque located behind the stent (PBS) are still poorly understood. We evaluated the serial changes in PBS following bare-metal (BMS) compared with first-generation drug-eluting stent (DES) implantation and the impact of these changes on in-stent neointimal hyperplasia (NIH). Methods: 3D coronary reconstruction by angiography and intravascular ultrasound were serially performed after intervention and at 6- to 10-month follow-up in 157 Japanese patients treated with BMS (n=90) and DES (n=98; 68 sirolimus-eluting and 30 paclitaxel-eluting stents) included in the PREDICTION Study. Each reconstructed stented coronary artery was divided into consecutive 1.5-mm segments. External elastic lamina, lumen, stent, and PBS area were measured for each segment at both baseline and follow-up. At follow-up NIH area was assessed. Due to the very low rate of events in our population we used significant NIH (defined as NIH area >50% of stent area) as a binary anatomic outcome. Results: Patient, lesion, and stent characteristics were comparable between BMS and DES. There was a significant decrease in PBS area after BMS (median relative change: -7.2%, IQR -19.3 to 5.2%, p Conclusions: The PBS significantly decreased 6 to 10 months after BMS implantation, whereas after DES it increased. The decrease in PBS area was significantly associated with the development of NIH at follow-up in both stent types. These findings raise the possibility of a communication between the lesion within the stent and the underlying native atherosclerotic plaque, and may have important implications regarding the pathobiology of in-stent restenosis.

Abstract: Background: T-wave alternans is a marker of vulnerability to ventricular tachyarrhythmias and has been documented during myocardial ischemia associated with angioplasty, bypass graft occlusion, and episodes of Prinzmetal's variant angina. We examined whether this phenomenon was present during ambulatory ischemia in ten patients randomly selected from the placebo phase of the Angina and Silent Ischemia Study [ASIS]. Methods: The eligibility criteria for participation in the ASIS study were stable coronary disease, a positive exercise stress test, and verified ischemic episodes during ambulatory ECG (AECG) monitoring. For each patient, one ischemic episode was analyzed which met the criteria of > 2-mm ST segment depression for > 3 minutes with a relatively stable ST segment baseline of > 1 hour preceding the index episode. T-wave alternans was measured using the spectral analytical technique of complex demodulation. Results: In the stable coronary patients of the ASIS trial, we found that T-wave alternans magnitude nearly tripled from 0.27 ± 0.02 mV × ms before ischemia onset to 0.77 ± 0.08 mV × ms (P 2 mm and the ischemia-induced increase in T-wave alternans. Conclusions: We conclude that T-wave alternans often occurs in association with ambulatory ischemia. Thus, risk assessment in stable coronary patients may be enhanced by monitoring both ST segment deviation and T-wave alternans as they measure relevant but fundamentally different electrophysiological properties.

Abstract: Background: T-wave alternans has been increasingly implicated as a potential marker of vulnerability to ventricular tachyarrhythmias in both experimental and clinical investigations. However, the suitability of ambulatory ECG (AECG) recorders for monitoring this parameter has not been systematically studied. Methods: We evaluated the frequency response characteristics and performance in monitoring a computer simulated alternans signal in three brands of amplitude-modulated (AM) and one frequency-modulated (FM) recorder and compared the results to those of the reference digital AECG unit. Results: A common feature of the AM recorders was distortion due to electronic head resonance, particularly at heart rates in the range of 60–100 beats/min. The maximum distortion of T-wave morphology by the AM units was —6% to +28%. Conclusions: We conclude that digital and FM recorders are preferable for AECG monitoring of T-wave alternans. AM recorders can be used if the distortion is not excessive.

Abstract: Introduction: Low endothelial shear stress (ESS) activates pro-inflammatory pathways and is a powerful instigator of atherogenesis. Angiotensin receptor blockers and statins have been associated with anti-inflammatory actions in advanced plaques. However, their effect on the earliest pathobiologic manifestations of atherosclerosis has not been studied. We tested the hypothesis that valsartan (V) or V plus simvastatin (V/S) exerts an early vasculoprotective effect in coronary regions exposed to low ESS in a porcine model of human-like atherosclerosis. Methods: Twelve diabetic-hyperlipidemic swine (age: 3 mo) were grouped into controls (n=4), and those treated with V (320 mg; n=4) or V/S (320/40 mg; n=4). 3D reconstruction of coronary arteries by angiography and intravascular ultrasound was performed in vivo at 4 (baseline) and 8 (follow-up) wks post-induction. Baseline local ESS was calculated by computational fluid dynamics and 3 mm segments with low (≤1.2 Pa; n=46) or higher (>1.2 Pa; n=66) ESS were identified. Coronary arteries were harvested at follow-up. qRT-PCR was used for assessing the expression of intercellular adhesion molecule-1 (ICAM-1), monocyte chemoattractant protein-1 (MCP-1), LDL receptor and lipoprotein-associated phospholipase-A 2 (LpPLA 2 ). Results: The upregulation of ICAM-1, MCP-1, LDL receptor (p2 (p Conclusion: V and V/S attenuate the proatherogenic effects of low ESS within only 8 wks. These results suggest a drug-induced mechanism of regional atheroprotection early in the natural history of coronary artery disease.

Abstract: Introduction: Plaque inflammation is a critical step in the initiation and progression of atherosclerosis. Such inflammation is thought to originate from the luminal surface of plaque and infiltrate the intima-media in advanced lesions. Low endothelial shear stress (ESS) is known to induce intima-media inflammation and plaque growth. In this study we investigated in-vivo the hypothesis that low ESS induces also adventitial inflammation. Methods: We studied 11 swine at 23 (baseline) and 30 (followup) weeks after the induction of diabetes and hyperlipidemia. Using angiography and intravascular ultrasound data, we performed 3D coronary reconstruction of coronary arteries and calculated the ESS with computational fluid dynamics. In 56 segments, we assessed the adventitial inflammatory (CD45) and antigen-presenting (MHC-II) cell content at followup with immunohistochemistry. Segments were classified as low (≤ 1 Pa) or higher (>1 Pa) ESS. Results: MHC-II content in the adventitia (1.3±0.3%) was higher than in the media (0.3±0.1%, p Conclusion: Although total inflammation is not dependent on ESS, low ESS induces higher adventitial activated inflammatory cell content, as assessed by MHC-II immunostaining. This, in conjunction with the higher MHC-II content in the adventitia than in the media and the presence of an intact IEL suggests an additional source of inflammation in low-ESS plaque regions, originating from the vessel outer wall. The induction of neovascularization possibly accounts for this phenomenon.

Abstract: The purpose of this study was to assess the relationship between ischemia detected on continuous electrocardiographic (cECG) recording and cardiovascular outcomes after acute coronary syndrome (ACS).The small size of prior studies evaluating cECG prevented full evaluation of the risk associated with ischemia across subpopulations and compared with other methods of risk stratification. Ranolazine, a new antianginal agent, reduces ischemic symptoms in patients with chronic angina and after ACS but the anti-ischemic effect, as detected by cECG, is not known.In all, 6,560 patients hospitalized with non-ST-segment elevation ACS were randomly assigned to ranolazine or placebo in the MERLIN-TIMI 36 (Metabolic Efficiency With Ranolazine for Less Ischemia in Non-ST-Elevation Acute Coronary Syndrome-Thrombolysis In Myocardial Infarction 36) trial. The cECG was performed for 7 days after randomization. Outcomes were followed for a median of 348 days. Clinical events that occurred during cECG recording were excluded from analysis.A total of 6,355 (97%) patients had cECG recordings evaluable for ischemia analysis. Patients withor=1 episode of ischemia on cECG (n = 1,271, 20%) were at increased risk of cardiovascular death (7.7% vs. 2.7%, p0.001), MI (9.4% vs. 5.0%, p0.001), and recurrent ischemia (17.5% vs. 12.3%, p0.001). The relationship with cardiovascular death was independent of baseline characteristics or elevated biomarkers (adjusted hazard ratio: 2.46, p0.001). Ischemia on cECG was associated with significantly worse outcomes in several subgroups. Ranolazine did not reduce the rate of ischemia detected on cECG (19.9% vs. 21.0%, hazard ratio: 0.93, p = 0.21).In more than 6,300 patients with ACS, ischemia detected on cECG occurred frequently and was strongly and independently associated with poor cardiovascular outcomes, including cardiovascular death. Continuous ECG monitoring to detect ischemia after ACS may help to identify patients at increased risk.

Abstract: Background : ECG parameters such as low heart rate variability (HRV) identify patients at high risk post-ACS. We recently developed morphological variability (MV), a novel technique that quantifies differences in the morphology of entire beats using a dynamic time-warping algorithm. MV incorporates strictly more information than HRV, potentially offering a more complete evaluation of the ECG. We assessed the relationship among MV, HRV, and outcomes after NSTEACS. Methods: MV and HRV were calculated in 863 pts from the DISPERSE2 trial using the first 24 hrs of continuous ECG (CECG) after randomization for NSTEACS. Using each measure, pts were split into high and low variability groups (cutpoint for HRV (SDNN)= 75ms and for MV=0.7). Ischemia on CECG was defined as ≥1mm ST dep lasting ≥1min. Results: A total of 144 (16.7%) pts had high MV and 58 (6.7%) had low HRV. Pts with high MV experienced higher rates of death, death/MI/severe recurrent ischemia (SRI), and ischemia detected on CECG compared to low MV. (Table-Figure ) This relationship remained consistent in pts with no ischemia on CECG (hazard ratio for D/MI/SRI =2.5, p=0.016). There was no difference in mortality or ischemia on CECG in pts with low HRV v high HRV, but pts with low HRV did have higher rates of death/MI/SRI. (Table) Conclusions: MV correlates significantly with poor cardiovascular outcomes, including death, after NSTEACS, even after controlling for other high risk features and even among pts without electrocardiographic evidence of ischemia. MV may offer a new non-invasive measure for risk stratification after ACS.

Subjects: Physiology (medical), Cardiology and Cardiovascular Medicine
Abstract: Objectives: We investigated the role of V alone or in combination with S on the histomorphologic characteristics of thin cap fibroatheromas (TCFAs), and tested the hypothesis that V or VS attenuate the proinflammatory effect of low endothelial shear stress (ESS). We used vascular profiling of swine coronary arteries for in vivo assessment of ESS to prospectively identify these low ESS areas that are prone to develop TCFAs. Methods: 12 diabetic hyperlipidemic swine were allocated into 3 treatment groups: placebo (P, n=4), V (n=4) and VS (n=4). Blood pressure, serum cholesterol and glucose were similar between the treatment groups. IVUS-based geometrically correct 3D reconstruction of the coronary arteries was performed at baseline (wk 23) and follow up (wk 30). Baseline ESS was calculated using computational fluid dynamics and plaque-free subsegments of interest were identified (n=109). Coronary arteries (n=31) were harvested at follow up, cryosectioned at the subsegments of interest and stained histologically. Intima/media ratio and inflammation (CD45) were quantified. Lesions were classified into atheromas without evidence of fibrous cap (n=82) and TCFAs (n=60). Results: V alone or in combination with S reduced the amount of plaque inflammation, particularly in TCFAs (Fig A ). V and VS attenuated the proinflammatory effect of local low ESS compared to P (Fig B ). Conclusion: V alone or in combination with S exerts a stabilizing effect of reducing plaque inflammation, even in high-risk regions with low ESS. These results suggest a mechanism of regional atheroprotection associated with V or VS.

Abstract: The purpose of this study was to determine if ranolazine improves angina in stable coronary patients with persisting symptoms despite maximum recommended dose of amlodipine.Ranolazine is a unique antianginal agent that has been effective in stable angina, but it has not been studied in the setting of maximum recommended doses of conventional antianginal agents.Stable patients with coronary disease andor =3 anginal attacks per week despite maximum recommended dosage of amlodipine (10 mg/day) were randomized to 1,000 mg ranolazine or placebo twice a day for 6 weeks. Primary end point was the frequency of angina episodes per week during the double-blind treatment phase. Efficacy was also assessed by nitroglycerin consumption per week and the Seattle Angina Questionnaire (SAQ). Adjustment for multiple testing of secondary end points used a hierarchic closed testing procedure. Efficacy was assessed in subgroups based on baseline angina frequency, concomitant long-acting nitrate use, gender, and age. Safety was assessed by adverse events and electrocardiogram evaluations.A total of 565 patients were randomized: 281 patients to ranolazine and 284 patients to placebo. Baseline characteristics were similar between treatment groups. At baseline, angina frequency averaged 5.63 +/- 0.18 episodes/week, and nitroglycerin consumption averaged 4.72 +/- 0.21 tablets/week. Compared with placebo, ranolazine significantly reduced frequency of angina episodes (2.88 +/- 0.19 on ranolazine vs. 3.31 +/- 0.22 on placebo; p = 0.028) and nitroglycerin consumption (2.03 +/- 0.20 on ranolazine vs. 2.68 +/- 0.22; p = 0.014), with treatment effect that appeared consistent across subgroups. The median angina weekly episode rate at baseline was 4.5 per week. Subgroup analysis showed statistically significant reductions of angina frequency, nitroglycerin use, and SAQ angina frequency for patients with a baseline frequency4.5 per week but only of angina frequency for those with baseline frequencyor =4.5 per week. Patients with more frequent angina appeared to have a more pronounced treatment effect. No hemodynamic changes were observed. Ranolazine was well tolerated.Ranolazine significantly reduced frequency of angina and nitroglycerin consumption compared with placebo and was well tolerated.

Abstract: The goal of this study was to evaluate glycoprotein IIb/IIIa inhibition with eptifibatide when administered with indirect thrombin inhibition as compared with monotherapy with direct thrombin inhibition with bivalirudin among patients with non-ST-segment elevation acute coronary syndromes (ACS).The optimal combination of antiplatelet and antithrombin regimens that maximizes efficacy and minimizes bleeding among patients with non-ST-segment elevation ACS undergoing percutaneous coronary intervention (PCI) is unclear.A total of 857 patients with non-ST-segment elevation ACS were assigned randomly to eptifibatide + reduced dose unfractionated heparin (n = 298), eptifibatide + reduced-dose enoxaparin (n = 275), or bivalirudin monotherapy (n = 284).Among angiographically evaluable patients (n = 754), the primary end point of post-PCI coronary flow reserve was significantly greater with bivalirudin (1.43 vs. 1.33 for pooled eptifibatide arms, p = 0.036). Thrombolysis In Myocardial Infarction (TIMI) myocardial perfusion grade more often was normal with eptifibatide treatment compared with bivalirudin (57.9% vs. 50.9%, p = 0.048). The duration of ischemia on continuous Holter monitoring after PCI was significantly longer among patients treated with bivalirudin (169 vs. 36 min, p = 0.013). There was no excess of TIMI major bleeding among patients treated with eptifibatide compared with bivalirudin (0.7%, n = 4 vs. 0%, p = NS), but TIMI minor bleeding was increased (2.5% vs. 0.4%, p = 0.027) as was transfusion (4.4% to 0.4%, p0.001).Among moderate- to high-risk patients with ACS undergoing PCI, coronary flow reserve was greater with bivalirudin than eptifibatide. Eptifibatide improved myocardial perfusion and reduced the duration of post-PCI ischemia but was associated with higher minor bleeding and transfusion rates. Ischemic events and biomarkers for myonecrosis, inflammation, and thrombin generation did not differ between agents.

Abstract: Improvements in solid-state digital technology have enhanced transtelephonic transmission of electrocardiography (ECG) data and increased the accuracy of software-based analysis systems. These advances, in addition to better signal quality and greater computer arrhythmia interpretation capabilities, have opened new potential uses for ambulatory electrocardiography (AECG). Traditional uses of AECG for arrhythmia detection have expanded as the result of increased use of multichannel and telemetered signals. The clinical application of arrhythmia monitoring to assess drug and device efficacy has been further defined by new studies. The analysis of transient ST-segment deviation remains controversial, but considerably more data are now available, especially about the prognostic value of detecting asymptomatic ischemia. Heart rate variability (HRV) analysis has shown promise for predicting mortality rates in cardiac patients at high risk. Despite these advances, a true automated analysis system has not been perfected and technician/physician participation is still essential. The widespread availability and low cost of personal computers and workstations has allowed for the development of extremely sophisticated and automated signal processing algorithms. Current AECG equipment provides for the detection and analysis of arrhythmias and ST-segment deviation as well as more sophisticated analyses of R-R intervals, QRS-T morphology including late potentials, Q-T dispersion, and T-wave alternans. There are 2 categories of AECG recorders: continuous recorders, typically used for 24 to 48 hours to investigate symptoms and ECG events that are likely to occur within that time frame, and intermittent recorders, which may be used for long periods of time (weeks to months) to provide briefer, intermittent recordings for investigating events that occur infrequently. ### A. Continuous Recorders Rapidly evolving technologies now allow for direct recording of the ECG signal in a digital format using solid-state recording devices.

45. Nonlinear equilibration of baroclinic eddies : the role of boundary layer processes and seasonal forcing

Abstract: Thesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Earth, Atmospheric, and Planetary Sciences, 2009., This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections., Cataloged from student submitted PDF version of thesis., Includes bibliographical references (p. 257-266)., In this thesis, the influence of boundary layer processes and seasonal forcing on baroclinic eddy equilibration is studied to understand how the baroclinic adjustment is modified when taking into account these two factors. A modified [beta] plane multilevel quasi-geostrophic (QG) model with an interactive stratification and a simplified parameterization of atmospheric boundary layer physics is used as the atmospheric model in this study. Comparisons between experiments with the modified QG model and the traditional QG model with fixed stratification show that it is necessary to include the interaction between vertical eddy heat flux and stratification to obtain a realistic equilibrated state, i.e. robust isentropic slope. A slab surface model is also coupled with the atmospheric model to provide an interactive surface temperature distribution in some experiments in this study. The effect of boundary layer processes is first studied under the situation with fixed underlying surface temperature. The boundary layer vertical thermal diffusion, along with the surface heat exchange, is found primarily responsible for the limitation of the PV homogenization in the boundary layer. The boundary layer processes can influence the eddy activity in at least two competing ways. First, in the eddy energy budget, all the boundary layer processes act to damp the eddy energy directly. On the other hand, the boundary layer processes also influence the mean flow, which can further influence the eddy behavior. For the boundary layer thermal damping, the indirect effect on the eddy activity becomes dominant., (cont.) Stronger boundary layer thermal forcing results in stronger meridional temperature gradients and eddy heat fluxes. For the frictional dissipation, the resulting changes in the zonal wind and in the location of the critical latitude lead to a meridional variation of the eddy forcing, which can further result in a non-monotonic response of the mean flow. The role of the boundary layer processes in the baroclinic eddy equilibration is further studied using a simple air-sea thermally coupled model. Although in the coupled system, each boundary layer process has more and different ways to influence the equilibrium state, their effect on the lower level PV homogenization is very robust. Surface friction and surface 3 heat flux all act to damp the lower level PV mixing and stronger surface damping prevents the PV homogenization more strongly, but the way in which each boundary layer process affects the PV homogenization is very different. Baroclinic eddy equilibration under seasonal forcing is studied in both the atmospheric model and the coupled model. In the situation with specified seasonal variation of the underlying surface temperature, a Northern-Hemisphere like seasonal variation of the surface temperature is used to act on the atmospheric flow through the boundary layer processes and the radiative-convective heating., (cont.) Under slowly varying seasonal forcing, the eddy and the mean flow behavior is characterized by four clearly divided time intervals: an eddy inactive time interval in the summer, a mainly dynamically determined eddy spinup time interval starting from mid-fall and lasting less than one month, a quasi-equilibrium time interval for the zonal mean flow available potential energy from late fall to late spring and a mainly external forcing determined eddy spindown time interval from late winter to late spring. In spite of the strong seasonality of the eddy activity, a robust PV structure is still observed through all the seasons. It is found that besides baroclinic eddies, the boundary layer thermal forcing as well as the moist convection all can help maintain the lower level PV structure. The sensitivity study of the eddy equilibration to the time scale of the external forcing also indicates that the time scale separation between the baroclinic adjustment and the external forcing in midlatitudes is only visible for external forcing cycle one year and longer. The seasonality study with the coupled model confirms the conclusions obtained in the uncoupled model., by Yang Zhang., Ph.D.

Abstract: Thesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Earth, Atmospheric, and Planetary Sciences, 2001., Includes bibliographical references (p. 183-193)., The focus of this thesis is the sensitivity of the strength of the meridional overturning circulation to surface forcing and mixing on climatological time scales. An adjoint model is used to gain new insights into the spatial characteristics of the sensitivity patterns. Adjoint models provide the sensitivity of a diagnostic, often called cost function, to all model parameters in a single integration. In contrast, traditional sensitivity analyses are performed by repeated integrations of the so-called "forward" model, perturbing slightly the value of a single parameter at each integration. The results of the adjoint model allows us to calculate global maps of sensitivity. These maps provide a geographic picture of where on the ocean heat and freshwater flux, wind stress and diapycnal mixing perturbations in the North Atlantic are likely to have the greatest impact on the meridional overturning and its heat transport. The adjoint model provides clear identification of the physical mechanisms which can influence the meridional overturning on times scales of years to decades. Boundary and equatorial Kelvin waves and equatorially trapped Rossby waves carry information around the boundaries of the basin and across the equator in less than a decade for a basin of the size of the Atlantic. Advection of buoyancy perturbations has an important influence on the meridional overturning on the decadal time scale. Diffusion is important in determining the final equilibrated state of the meridional overturning on the centennial scale. The role of diapycnal mixing in determining the overturning's strength is confined to regions near the lateral boundaries in the Northern hemisphere and to the tropical region in both hemispheres. The important role played by the tropics in setting the overturning's strength seems to confirm the thermodynamic principles outlined by Sandstrom (1908), Jeffreys (1925) and Munk and Wunsch (1998): upward advection of heat is balanced by downward diffusion., by Véronique Bugnion., Ph.D.
