Abstract
BACKGROUND Clinical trials in heart failure (HF) traditionally use time-to-event analyses focusing on death and hospitalization for HF. These time-to-first event analyses may have more limited abilities to assess the probability of benefiting from a therapy, especially if that benefit manifests as improved functional status rather than reduced risk of death or HF hospitalization. Hierarchical end points including clinical outcomes and patient status measures allow for ranked evaluation of outcomes in 1 metric assessing whether patients randomized to intervention or control are more likely to derive an overall benefit while also allowing more patients to contribute to the primary outcome. METHODS We review the rationale for using hierarchical end points in HF trials, provide examples of HF trials that used this type of end point, and discuss its use in the HEART-FID trial (Randomized Placebo-Controlled Trial of Ferric Carboxymaltose as Treatment for Heart Failure With Iron Deficiency), the largest HF trial to date implementing a hierarchical end point analysis for the primary outcome. RESULTS Using a hierarchical end point as the primary outcome allows for the inclusion of different types of outcomes in 1 ranked end point, making it possible to more holistically assess the potential utility of a new therapy on patient well-being and outcomes. CONCLUSIONS Hierarchical end points assess the potential utility of a new therapy on patient well-being and outcome more holistically than time-to-first event analysis. Trials that would not have been feasible due to decreasing rates of death and hospitalization in the HF population can use hierarchical end points to successfully power studies to identify promising HF therapies. The HEART-FID trial used hierarchical end points to better determine the role of intravenous ferric carboxymaltose in patients with HF.

Abstract
BACKGROUND Prior clinical trials have investigated intravenous iron in patients with heart failure (HF) and iron deficiency, but the safety and efficacy of this therapy remains unclear. METHODS We report the baseline demographics and clinical characteristics of patients enrolled in the HEART-FID study and compare HEART-FID participants with patients within other contemporary clinical trials of patients with HF with reduced ejection fraction (HFrEF), including other intravenous iron trials. RESULTS In the 3,065 participants randomized in HEART-FID, median (IQR) age was 69.7 (62.0-76.5) years, 1,037 (33.8%) were female, 322 (10.5%) were Black, median ejection fraction was 32% (25%-37%), 1,837 (60.0%) had ischemic etiology, and baseline median NT-proBNP was 1,462 (721-2,966) pg/mL. Median baseline hemoglobin was 12.6 (11.6-13.6) g/dL, and median 6-minute walk test distance was 272 (196-350) m, similar to prior intravenous iron HFrEF trials. Common comorbidities included atrial fibrillation/flutter (43.7%), and type 2 diabetes (45.2%). Compared with several recent HFrEF trials, patients enrolled in HEART-FID had similar baseline demographics and clinical characteristics, though a greater proportion of women and Black participants were recruited in HEART-FID. In HEART-FID, HFrEF therapy included a beta-blocker in 92.5%, angiotensin-converting enzyme inhibitor/angiotensin receptor blocker/angiotensin receptor-neprilysin inhibitors (ARNI) in 86.1% (with 29.7% ARNI), and a mineralocorticoid antagonist (MRA) in 55.6%. CONCLUSIONS Patients enrolled in HEART-FID were similar to those enrolled in other contemporary HFrEF trials and registries, including trials of intravenous iron in HFrEF. However, the HEART-FID cohort is substantially larger and more racially diverse than prior trials of intravenous iron in HFrEF. TRIAL REGISTRATION ClinicalTrials.gov (NCT03037931).

Abstract
BACKGROUND Recent clinical trials have demonstrated that sodium-glucose cotransporter 2 inhibitors (SGLT2i), which were previously only indicated in treatment of type 2 diabetes mellitus (T2DM), can markedly reduce heart failure hospitalisation (HFH), with less striking potential reductions in acute coronary syndromes and cardiac arrhythmias. To evaluate the impact of SGLT2i on cardiovascular outcomes in real-world practice, we performed a retrospective cohort analysis on South Australian (SA) data. METHODS A total of 842 individuals with T2DM receiving SGLT2i were identified from SA public hospitals between 2011 and 2019. Episodes of care were temporally matched with those of 3,128 individuals with T2DM not receiving SGLT2i (control). Baseline characteristics were adjusted using inverse probability treatment weighting. The incidence of cardiovascular events at 12 and 24 months was evaluated using coded (International Classification of Diseases, Tenth Revision, Australian Modification [ICD-10-AM]) data. RESULTS The primary outcome of HFH was lower with SGLT2i use at 12 months (adjusted hazard ratio [HRadj] 0.44; 95% confidence interval [CI] 0.29-0.68; p<0.001) and 24 months. There were also lower hospitalisations due to acute myocardial infarction (HRadj 0.42; 95% CI 0.21-0.85; p=0.015) and atrial or ventricular arrhythmias (HRadj 0.29; 95% CI 0.14-0.59; p=0.001), with no difference observed in hospitalisation due to ischaemic cerebrovascular events. There was no difference in all-cause mortality at 12 months but interestingly a higher rate at 24 months (HRadj 2.08; 95% CI 1.59-2.72; p<0.001). Despite this, similar reductions in cardiovascular outcomes were observed at 24 months. CONCLUSION Use of SGLT2i in patients with T2DM in SA was associated with reductions in cardiovascular events even before their recent Pharmaceutical Benefits Scheme (PBS) listing for heart failure. Furthermore, this analysis supports that SGLT2i play a role not only in HFH reduction but also in reducing coronary and tachyarrhythmic events. This real-world evidence supports the use of SGLT2i as broadly protective cardiovascular drugs.

Abstract
BACKGROUND Ferric carboxymaltose therapy reduces symptoms and improves quality of life in patients who have heart failure with a reduced ejection fraction and iron deficiency. Additional evidence about the effects of ferric carboxymaltose on clinical events is needed. METHODS In this double-blind, randomized trial, we assigned ambulatory patients with heart failure, a left ventricular ejection fraction of 40% or less, and iron deficiency, in a 1:1 ratio, to receive intravenous ferric carboxymaltose or placebo, in addition to standard therapy for heart failure. Ferric carboxymaltose or placebo was given every 6 months as needed on the basis of iron indexes and hemoglobin levels. The primary outcome was a hierarchical composite of death within 12 months after randomization, hospitalizations for heart failure within 12 months after randomization, or change from baseline to 6 months in the 6-minute walk distance. The significance level was set at 0.01. RESULTS We enrolled 3065 patients, of whom 1532 were randomly assigned to the ferric carboxymaltose group and 1533 to the placebo group. Death by month 12 occurred in 131 patients (8.6%) in the ferric carboxymaltose group and 158 (10.3%) in the placebo group; a total of 297 and 332 hospitalizations for heart failure, respectively, occurred by month 12; and the mean (±SD) change from baseline to 6 months in the 6-minute walk distance was 8±60 and 4±59 m, respectively (Wilcoxon-Mann-Whitney P = 0.02; unmatched win ratio, 1.10; 99% confidence interval, 0.99 to 1.23). Repeated dosing of ferric carboxymaltose appeared to be safe with an acceptable adverse-event profile in the majority of patients. The number of patients with serious adverse events occurring during the treatment period was similar in the two groups (413 patients [27.0%] in the ferric carboxymaltose group and 401 [26.2%] in the placebo group). CONCLUSIONS Among ambulatory patients who had heart failure with a reduced ejection fraction and iron deficiency, there was no apparent difference between ferric carboxymaltose and placebo with respect to the hierarchical composite of death, hospitalizations for heart failure, or 6-minute walk distance.

Abstract
BACKGROUND Dyspnea, the cardinal manifestation of chronic heart failure (CHF), may reflect both pulmonary oedema and pulmonary remodeling resulting in tissue stiffening. Emerging evidence suggests that predominance of distinct phenotypes of alveolar and recruited macrophages, designated M1 and M2, may regulate the course of inflammatory tissue repair and remodeling in the lung. METHODS In a CHF rat model, we found fibrotic reinforcement of the extracellular matrix with an increase in monocyte chemotactic protein (MCP)-1/CCL2 in bronchoalveolar lavage (BAL), corresponding to a 3-fold increase in recruited macrophages. In this clinical cross sectional study, we aimed to examine potential mediators of leukocyte activation and lung infiltration in parallel BAL and blood from CHF patients compared to non-CHF controls. RESULTS Mini-BAL and peripheral blood samples were obtained from hospitalized CHF, acute decompensated CHF and non-CHF patients. CHF patients and decompensated CHF patients demonstrated increases from non-CHF patients in BAL MCP-1, as well as the M2 macrophage cytokines interleukin-10 and transforming growth factor-β. BAL and plasma MCP-1 were significantly correlated; however, MCP-1 was 20-fold higher in epithelial lining fluid in BAL, indicative of an alveolar chemotactic gradient. An increase in transglutaminase 2 positive M2 macrophages in parallel with a decrease in the MCP-1 receptor, CC chemokine receptor 2 (CCR2), was apparent in BAL cells of CHF patients compared to non-CHF. CONCLUSION These data suggest a pathway of MCP-1 mediated M2 macrophage prevalence in the lungs of CHF patients which may contribute to pulmonary fibrotic remodeling and consequent increased severity of dyspnea.

Abstract
BACKGROUND In patients who survive an acute myocardial infarction (AMI), angiotensin-converting enzyme inhibitors decrease the risk of subsequent major cardiovascular events. Whether angiotensin-receptor blockade and neprilysin inhibition with sacubitril/valsartan reduce major coronary events more effectively than angiotensin-converting enzyme inhibitors in high-risk patients with recent AMI remains unknown. We aimed to compare the effects of sacubitril/valsartan on coronary outcomes in patients with AMI. METHODS We conducted a prespecified analysis of the PARADISE-MI trial (Prospective ARNI vs ACE Inhibitors Trial to Determine Superiority in Reducing Heart Failure Events After MI), which compared sacubitril/valsartan (97/103 mg twice daily) with ramipril (5 mg twice daily) for reducing heart failure events after myocardial infarction in 5661 patients with AMI complicated by left ventricular systolic dysfunction, pulmonary congestion, or both. In the present analysis, the prespecified composite coronary outcome was the first occurrence of death from coronary heart disease, nonfatal myocardial infarction, hospitalization for angina, or postrandomization coronary revascularization. RESULTS Patients were randomly assigned at a median of 4.4 [3.0-5.8] days after index AMI (ST-segment-elevation myocardial infarction 76%, non-ST-segment-elevation myocardial infarction 24%), by which time 89% of patients had undergone coronary reperfusion. Compared with ramipril, sacubitril/valsartan decreased the risk of coronary outcomes (hazard ratio, 0.86 [95% CI, 0.74-0.99], P=0.04) over a median follow-up of 22 months. Rates of the components of the composite outcomes were lower in patients on sacubitril/valsartan but were not individually significantly different. CONCLUSIONS In survivors of an AMI with left ventricular systolic dysfunction and pulmonary congestion, sacubitril/valsartan-compared with ramipril-reduced the risk of a prespecified major coronary composite outcome. Dedicated studies are necessary to confirm this finding and elucidate its mechanism. REGISTRATION URL: https://www. CLINICALTRIALS gov; Unique identifier: NCT02924727.

Abstract
BACKGROUND In patients with symptomatic heart failure, sacubitril-valsartan has been found to reduce the risk of hospitalization and death from cardiovascular causes more effectively than an angiotensin-converting-enzyme inhibitor. Trials comparing the effects of these drugs in patients with acute myocardial infarction have been lacking. METHODS We randomly assigned patients with myocardial infarction complicated by a reduced left ventricular ejection fraction, pulmonary congestion, or both to receive either sacubitril-valsartan (97 mg of sacubitril and 103 mg of valsartan twice daily) or ramipril (5 mg twice daily) in addition to recommended therapy. The primary outcome was death from cardiovascular causes or incident heart failure (outpatient symptomatic heart failure or heart failure leading to hospitalization), whichever occurred first. RESULTS A total of 5661 patients underwent randomization; 2830 were assigned to receive sacubitril-valsartan and 2831 to receive ramipril. Over a median of 22 months, a primary-outcome event occurred in 338 patients (11.9%) in the sacubitril-valsartan group and in 373 patients (13.2%) in the ramipril group (hazard ratio, 0.90; 95% confidence interval [CI], 0.78 to 1.04; P = 0.17). Death from cardiovascular causes or hospitalization for heart failure occurred in 308 patients (10.9%) in the sacubitril-valsartan group and in 335 patients (11.8%) in the ramipril group (hazard ratio, 0.91; 95% CI, 0.78 to 1.07); death from cardiovascular causes in 168 (5.9%) and 191 (6.7%), respectively (hazard ratio, 0.87; 95% CI, 0.71 to 1.08); and death from any cause in 213 (7.5%) and 242 (8.5%), respectively (hazard ratio, 0.88; 95% CI, 0.73 to 1.05). Treatment was discontinued because of an adverse event in 357 patients (12.6%) in the sacubitril-valsartan group and 379 patients (13.4%) in the ramipril group. CONCLUSIONS Sacubitril-valsartan was not associated with a significantly lower incidence of death from cardiovascular causes or incident heart failure than ramipril among patients with acute myocardial infarction.

Abstract
INTRODUCTION Experienced echocardiographers can quickly glean diagnostic information from limited echocardiographic views. The use of limited cardiac ultrasound, particularly as a screening tool, is increasing. During the COVID-19 pandemic, limited cardiac ultrasound has the major advantage of reducing exposure time between sonographer and patient. The sensitivity and negative predictive value of a "screening" echocardiogram with highly limited views is uncertain. AIM/METHOD We examined the accuracy of limited echocardiography in 203 consecutive, de novo studies. We used six images: parasternal long axis, with colour Doppler over the mitral valve, and aortic valve, and apical four-chamber with colour Doppler over the mitral valve, and tricuspid valve. We compared the interpretation of 12 subjects with the final echocardiogram report, (gold standard). The subjects comprised four experienced echocardiography-specialised cardiologists, four experienced cardiologists with non-imaging subspecialty interests, and four senior cardiac sonographers. Studies were graded as: (1) normal or (2) needs full study (due to inadequate images or abnormality detected). Sensitivity, specificity, negative predictive value, positive predictive value and accuracy are reported. RESULTS Forty-one per cent (41%) of studies were normal by the gold standard report. Overall, a screening echocardiogram had a sensitivity of 71.2%, specificity of 57.1% to detect an abnormal echocardiogram, negative predictive value 58.4%, positive predictive value of 70.2%, and accuracy of 65.4%. When inadequate images were excluded, overall accuracy was nearly identical at 64.6%. The overall accuracy between the three groups of interpreters was similar: 66.5% (95% CI 63.1-69.7) for echocardiography-specialised cardiologists, 65.3% (95% CI 61.9-68.5) for non-echocardiography specialised cardiologists, and 64.4% (95% CI 61.0-67.7) for sonographers. These groups are all highly experienced practitioners. There was no difference in sensitivity or specificity comparing echocardiography-specialised cardiologists with cardiologists of other subspecialty experience. Comparing cardiologists to sonographers, cardiologists had lower sensitivity (echocardiography specialists 67.6%, 95% CI 63.2-71.8, non-echocardiography specialists 62.0%, 95% CI 57.4-66.4) compared to sonographers (84.0% [95% CI 80.4-87.2, p<0.05]), but cardiologists had higher specificities (64.9% [95% CI 59.5-70.0] for the echocardiography specialists, and 69.9% [95% CI 64.7-74.8] for non echocardiography specialists), compared to 36.6% (95% CI 31.4-42.0, p<0.05) for the sonographer group. When looking at only the studies considered to be interpretable, cardiologists had higher positive predictive value (echocardiography specialists 73.7%, 95% CI 69.0-78.1, non echocardiography specialists 74.1%, 95% CI 68.8-79.9), as compared to sonographers (64.3%, 95% CI 59.8-68.5%). CONCLUSIONS Limited cardiac ultrasound as a screening tool for a normal heart had a sensitivity of only 71%, when performed and interpreted by experienced personnel, raising questions regarding the safety of this practice. Caution is especially recommended in extrapolating its use to non-specialised settings.

Abstract
OBJECTIVE Frailty is common in the aortic stenosis (AS) population and impacts outcomes after both transcatheter and surgical aortic valve replacement (TAVR and sAVR, respectively). Frailty can significantly impact the decision regarding the suitability of a patient for aortic valve intervention, with frail patients often excluded. Since many frailty tools use indicators which may be influenced by AS itself, some of which are subjectively symptom driven, we sought to determine the impact of intervention on frailty scores. METHODS A prospective, observational cohort study included patients being assessed for aortic valve (AV) intervention with either TAVR or sAVR due to severe aortic stenosis. Patients were assessed for symptoms at baseline, and 1- and 6-months post intervention subjectively, using the New York Heart Association (NYHA) class and the Kansas City Cardiomyopathy Questionnaire (KCCQ), and objectively, using a 6-minute walk test (6MWT). These were compared with frailty at baseline and final review using the Fried Frailty Scale (FFS). RESULTS AND CONCLUSIONS Sixty-six (66) patients completed pre- and post-intervention reviews. The mean FFS score was significantly lower, indicating less frailty, at 6 months relative to pre procedure (1.18 vs 1.73, p=0.002). This correlated with the change in symptoms (p<0.001). Between intervention groups, the final mean FFS of both groups decreased significantly, with TAVR to 1.33 (p=0.030) and sAVR to 0.8 (p=0.015). There was no difference in the degree of improvement between interventions (p=0.517). Aortic valve intervention improves frailty scores in both TAVR and sAVR treated patients.

Abstract
Aims This study aimed to explore the rapid effects of dapagliflozin in heart failure with reduced ejection fraction (HFrEF). Methods and results We studied the functional, echocardiographic, electrophysiological, lung ultrasound, ambulatory blood pressure (BP), microvascular and macrovascular function, and biochemical effects of 2 week treatment with dapagliflozin in 19 type 2 diabetic HFrEF patients in a double‐blind, crossover, placebo‐controlled trial. Dapagliflozin had no significant effect on clinical, functional, or quality of life parameters. Dapagliflozin reduced systolic BP [114 (105, 131) vs. 106 (98, 113) mmHg, P < 0.01] and diastolic BP [71 (61, 78) vs. 62 (55, 70) mmHg, P < 0.01]. There was no effect on cardiac chamber size, ventricular systolic function, lung ultrasound, or arterial wave reflection. Dapagliflozin increased creatinine [117 (92, 129) vs. 122 (107, 135) μmol/L, P < 0.05] and haemoglobin [135 (118, 138) vs. 136 (123, 144) g/L, P < 0.05]. There was a reduction in ventricular ectopy [1.4 (0.1, 2.9) vs. 0.2 (0.1, 1.4) %, P < 0.05] and an increase in standard deviation of normal heart beat intervals [70 (58, 90) vs. 74 (62, 103), P < 0.05]. Unexpectedly, dapagliflozin increased high‐sensitivity troponin T [25 (19, 37) vs. 28 (20, 42) ng/L, P < 0.01] and reduced reactive hyperaemia index [1.29 (1.21, 1.56) vs. 1.40 (1.23, 1.84), P < 0.05]. Conclusions After 2 weeks, while multiple parameters supported BP reduction and haemoconcentration with dapagliflozin, reduction in cardiac filling pressure, lung water, and functional improvement was not shown. Reduced ventricular ectopic burden suggests an early antiarrhythmic benefit. The small increase in troponin T and the reduction in the reactive hyperaemia index warrant further mechanistic exploration in this treatment of proven mortality benefit in HFrEF.

Abstract
BACKGROUND Iron deficiency (ID) has a prevalence of ≈40% to 50% among patients in heart failure (HF) with reduced ejection fraction and is associated with worse prognosis. Several trials demonstrated that intravenous ferric carboxymaltose leads to early and sustained improvement in patient-reported outcomes and functional capacity in patients with HF with reduced ejection fraction with ID, yet morbidity and mortality data are limited. METHODS The objective of the HEART-FID trial (Ferric Carboxymaltose in Heart Failure With Iron Deficiency) is to assess efficacy and safety of ferric carboxymaltose compared with placebo as treatment for symptomatic HF with reduced ejection fraction with ID. HEART-FID is a multicenter, randomized, double-blind, placebo-controlled trial enrolling ≈3014 patients at ≈300 international centers. Eligible patients are aged ≥18 years in stable chronic HF with New York Heart Association functional class II to IV symptoms, ejection fraction ≤40%, ID (ferritin <100 ng/mL or ferritin 100-300 ng/mL with a transferrin saturation <20%), and documented HF hospitalization or elevated N-terminal pro-brain natriuretic peptide. Consented patients are assigned to ferric carboxymaltose or placebo at baseline, with repeated visits/assessments every 6 months for additional study drug based on hemoglobin and iron indices for the trial duration. The primary end point is a hierarchical composite of death and HF hospitalization at 12 months and change from baseline to 6 months in the 6-minute walk test distance. CONCLUSIONS The HEART-FID trial will inform clinical practice by clarifying the role of long-term treatment with intravenous ferric carboxymaltose, added to usual care, in ambulatory patients with symptomatic HF with reduced ejection fraction with ID.

Abstract
BACKGROUND In pulmonary arterial hypertension (PAH), progressive right ventricular (RV) dysfunction is believed to be largely secondary to RV ischaemia. A recent pilot study has demonstrated the feasibility of Oxygen-sensitive (OS) cardiovascular magnetic resonance (CMR) to detect in-vivo RV myocardial oxygenation. The aims of the present study therefore, were to assess the prevalence of RV myocardial ischaemia and relationship with RV myocardial interstitial changes in PAH patients with non-obstructive coronaries, and corelate with functional and haemodynamic parameters. METHODS We prospectively recruited 42 patients with right heart catheter (RHC) proven PAH and 11 healthy age matched controls. The CMR examination involved standard functional imaging, OS-CMR imaging and native T1 mapping. An ΔOS-CMR signal intensity (SI) index (stress/rest signal intensity) was acquired at RV anterior, RV free-wall and RV inferior segments. T1 maps were acquired using Shortened Modified Look-Locker Inversion recovery (ShMOLLI) at the inferior RV segment. RESULTS The inferior RV ΔOS-CMR SI index was significantly lower in PAH patients compared with healthy controls (9.5 (- 7.4-42.8) vs 12.5 (9-24.6)%, p = 0.02). The inferior RV ΔOS-CMR SI had a significant correlation to RV inferior wall thickness (r = - 0.7, p < 0.001) and RHC mean pulmonary artery pressure (mPAP) (r = - 0.4, p = 0.02). Compared to healthy controls, patients with PAH had higher native T1 in the inferior RV wall: 1303 (1107-1612) vs 1232 (1159-1288)ms, p = 0.049. In addition, there was a significant difference in the inferior RV T1 values between the idiopathic PAH and systemic sclerosis associated PAH patients: 1242 (1107-1612) vs 1386 (1219-1552)ms, p = 0.007. CONCLUSION Blunted OS-CMR SI suggests the presence of in-vivo microvascular RV dysfunction in PAH patients. The native T1 in the inferior RV segments is significantly increased in the PAH patients, particularly among the systemic sclerosis associated PAH group.

Abstract
Background Aortic stenosis (AS) is a common valvular disorder with a large symptomatic burden resulting from increased myocardial workload due to valvular obstruction. The contribution of increased afterload from arterial stiffness on symptoms is uncertain. The purpose of this analysis was to determine the symptomatic impact of arterial stiffness as determined by Applanation Tonometry. Methods Eighty-eight patients with severe AS undergoing intervention with transcatheter aortic valve replacement (TAVR) (n = 65) or surgical aortic valve replacement (SAVR) (n = 23) were prospectively enrolled. Symptoms were recorded using the NYHA Class, Kansas City Cardiomyopathy Questionnaire (KCCQ) and a 6 min walk test (6MWT) at baseline, and 1- and 6-months post intervention. Pulse Wave Analysis (PWA) using Applanation Tonometry was performed at all reviews, including the augmentation index (AIx). Results Patients undergoing TAVR were older, with worse renal function and lower aortic valve areas, but were otherwise similar. There was no significant difference between the augmentation index of our AS population compared with an age matched reference population (p = 0.89). Symptoms significantly improved after intervention according to NYHA Class, KCCQ and 6MWT. Additionally, with adjustment, the initial augmentation index correlated with the final KCCQ (Coeff. = −0.383, p = 0.02) and NYHA Class (Coeff. = 0.012, p = 0.03) and a baseline AIx value in the top quartile resulted in a significantly worse final KCCQ (95.1 v 85.2, p = 0.048) relative to the bottom 3 quartiles. Conclusions According to our analysis, an elevated baseline AIx is associated with a poorer symptomatic recovery after aortic valve intervention and so is worthy of consideration when assessing potential symptomatic benefit.

Abstract
Background Prognosis in pulmonary arterial hypertension (PAH) is largely dependent on right ventricular (RV) function. However, recent studies have suggested the presence of left ventricular (LV) dysfunction in PAH patients. The potential role of LV ischemia, as a contributor to progressive LV dysfunction, has not been systematically studied in PAH. We aim to assess the presence and extent of LV myocardial ischemia in patients with known PH and without obstructive coronary artery disease (CAD), using oxygen-sensitive (OS) cardiovascular magnetic resonance (CMR) and stress/rest CMR T1 mapping. Methods We prospectively recruited 28 patients with right heart catheter-proven PH and no significant CAD, 8 patients with known CAD and 11 normal age-matched controls (NC). OS-CMR images were acquired using a T2* sequence and T1 maps were acquired using Shortened Modified Look-Locker Inversion recovery (ShMOLLI) at rest and adenosine-induced stress vasodilatation; ΔOS-CMR signal intensity (SI) index (stress/rest SI) and ΔT1 reactivity (stress-rest/rest T1 mapping) were calculated. Results Global LV ΔOS SI index was significantly lower in PH patients compared with controls (11.1%±6.7% vs. 20.5%±10.5%, P=0.016), as was ΔT1 reactivity (5.2%±4.5% vs. 8.0%±2.9%, P=0.047). The ischemic segments of CAD patients had comparable ΔOS SI (10.3%±6.4% vs. 11.1%±6.7%, P=0.773) to PH patients, but lower ΔT1 reactivity (1.1%±4.2% vs. 5.2%±4.5%, P=0.036). Conclusions Decreased OS-CMR SI and T1 reactivity signify the presence of impaired myocardial oxygenation and vasodilatory response in PH patients. Given their unobstructed epicardial coronary arteries, this is likely secondary to coronary microvascular dysfunction (CMD).

Abstract
BACKGROUND Hydrostatic lung injury followed by pulmonary remodelling variably complicates cardiogenic acute pulmonary oedema (APO). Pulmonary remodelling may be regulated by the balance between distinct phenotypes of pulmonary macrophages; activated/inflammatory (M1), and reparative/anti-inflammatory (M2), derived from circulating monocyte populations. The aim of this study was to identify biomarkers in peripheral blood that are consistent with hydrostatic lung injury and pulmonary remodelling in APO and which follow the variable clinical course. METHODS To examine peripheral markers of lung inflammation, resolution and remodelling, 18 patients, admitted to the intensive care unit (ICU) with a clinical diagnosis of APO, were enrolled. Admission, 12- and 24-hour post-admission bloods were assayed for cytokines by ELISA (R&D Systems, Minneapolis, MN, USA) and leukocyte surface markers by flow cytometry. RESULTS Admission PaO2 to FiO2 ratio was positively correlated with Mon 2 (intermediate) monocyte prevalence, through increasing ratio of CD16+ monocytes to CD11b+ and CD40+ monocytes, and negatively correlated with Mon 1 (classical) monocyte prevalence, through decreasing ratio of CD16+ monocytes to CD62L+. Secondary cohort analysis compared 10 APO patients with established chronic heart failure (CHF) to eight without CHF. An increase in monocyte chemotactic peptide (MCP)-1, monocyte prevalence, and CD16-CD62L+ monocytes with CHF, all characteristic of monocyte activation to a Mon 1 phenotype, were found in the CHF APO patients. CONCLUSIONS Increased systemic monocyte prevalence and expression of cell surface markers suggest a Mon 1 profile in CHF patients during episodes of APO. Future studies should define the role of systemic monocyte prevalence and activation in decompensated CHF.

Abstract
Background Progressive right ventricular (RV) dysfunction in pulmonary arterial hypertension (PAH) which is contributed by RV ischemia leads to adverse clinical outcomes. Oxygen-sensitive (OS) cardiovascular magnetic resonance (CMR) has been used to determine the in vivo myocardial oxygenation of the left ventricle (LV). The aims of the present study were therefore to determine the feasibility of RV targeted rest/stress OS-CMR imaging in PAH patients and healthy volunteers. Methods We prospectively recruited 20 patients with right heart catheter proven PAH and 9 healthy age matched controls (NC). The CMR examination involved standard functional imaging and OS-CMR imaging. An OS-CMR signal intensity (SI) index (stress/rest SI) was acquired at RV anterior, RV free-wall and RV inferior segments. In the LV, the OS-CMR SI index was acquired globally. Results Reliable OS SI changes were only obtained from the RV inferior segment. As RV dysfunction in PAH is a global process, hence this segment was used in both patients and NC for further comparison. RV OS-CMR SI change between rest and stress in the NC was 17%±5% (mean ± SD). Nine of 20 (45%) of the PAH patients had a mean OS SI change of less than 9% (or ≥2 SD different from the mean values in NC). Overall, RV OS SI index between the PAH patients and NC was 11%±9% vs. 17%±5% (P=0.045) in the RV inferior segment. In the LV, the global OS-CMR SI index between the PAH patients and NC was 11%±7% vs. 21%±9% (P=0.019). There was a strong correlation between RV Inf OS-CMR SI and LV OS-CMR SI (r=0.86, P<0.001). Conclusions In this small pilot study, pharmacological induced OS-CMR is a feasible and safe technique to identify and study myocardial oxygenation in the RV of PAH patients.

Abstract
Existing prediction algorithms for the identification of patients with heart failure (HF) at high risk of readmission or death after hospital discharge are only modestly effective. We sought to validate a recently developed predictive model of 30-day readmission or death in HF using an Australia-wide sample of patients. This study used data from 1,046 patients with HF at teaching hospitals in 5 Australian capital cities to validate a predictive model of 30-day readmission or death in HF. Besides standard clinical and administrative data, we collected data on individual sociodemographic and socioeconomic status, mental health (Patient Health Questionnaire [PHQ]-9 and Generalized Anxiety Disorder [GAD]-7 scale score), cognitive function (Montreal Cognitive Assessment [MoCA] score), and 2-dimensional echocardiograms. The original sample used to develop the predictive model and the validation sample had similar proportions of patients with an adverse event within 30 days (30% vs 29%, p = 0.35) and 90 days (52% vs 49%, p = 0.36). Applying the predicted risk score to the validation sample provided very good discriminatory power (C-statistic = 0.77) in the prediction of 30-day readmission or death. This discrimination was greater for predicting 30-day death (C-statistic = 0.85) than for predicting 30-day readmission (C-statistic = 0.73). There was a small difference in the performance of the predictive model among patients with either a left ventricular ejection fraction of <40% or a left ventricular ejection fraction of ≥40%, but an attenuation in discrimination when used to predict longer-term adverse outcomes. In conclusion, our findings confirm the generalizability of the predictive model that may be a powerful tool for targeting high-risk patients with HF for intensive management.

Abstract
Chronic elevation of pulmonary microvascular pressure (Pmv) consistently leads to alveolocapillary barrier thickening and reduction in the filtration coefficient. In animal models of chronic heart failure (CHF) the lung remains dry despite hydrostatic forces. As fluid flux is bi-directional, it has been postulated that an increase in alveolar fluid clearance may facilitate the dry lung when Pmv is chronically elevated. In this study we aimed to examine alveolar fluid clearance in ambulatory patients with CHF secondary to left ventricular (LV) systolic dysfunction compared against non-CHF controls. Lung clearance following aerosol delivery of 99mtechnetium (Tc)-diethyl triaminepentaacetic acid (DTPA) was measured non-invasively by scintigraphy and half time of 99mTc-DTPA clearance (T (1/2)) was calculated by mono-exponential curve fit. Alveolar fluid clearance measured as half time DTPA clearance was significantly faster in CHF patients than controls (P=0.001). This was further defined by NYHA classification. No correlation was found between DTPA clearance and plasma epinephrine, norepinephrine or aldosterone hormone (P>0.05). Our results support an association between increasing alveolar fluid clearance and disease severity in CHF, and the concept of controlled bi-directional fluid flux in CHF associated with increasing Pmv, and represents another defence mechanism of the lung against pulmonary oedema.

Abstract
BACKGROUND Cognitive impairment is highly prevalent in heart failure (HF), and may be associated with short-term readmission. This study investigated the role of cognition, incremental to other clinical and non-clinical factors, independent of depression and anxiety, in predicting 30-day readmission or death in HF. METHODS This study followed 565 patients from an Australia-wide HF longitudinal study. Cognitive function (MoCA score) together with standard clinical and non-clinical factors, mental health and 2D echocardiograms were collected before hospital discharge. The study outcomes were death and readmission within 30days of discharge. Logistic regression, Harrell's C-statistic, integrated discrimination improvement (IDI) and net reclassification index were used for analysis. RESULTS Among 565 patients, 255 (45%) had at least mild cognitive impairment (MoCA≤22). Death (n=43, 8%) and readmission (n=122, 21%) within 30days of discharge were more likely to occur among patients with mild cognitive impairment (OR=2.00, p=0.001). MoCA score was also negatively associated with 30-day readmission or death (OR=0.91, p<0.001) independent of other risk factors. Adding MoCA score to an existing prediction model of 30-day readmission significantly improved discrimination (C-statistic=0.715 vs. 0.617, IDI estimate 0.077, p<0.001). From prediction models developed from our study, adding MoCA score (C-statistic=0.83) provided incremental value to that of standard clinical and non-clinical factors (C-statistic=0.76) and echocardiogram parameters (C-statistic=0.81) in predicting 30-day readmission or death. Reclassification analysis suggests that addition of MoCA score improved classification for a net of 12% of patients with 30-day readmission or death and of 6% of patients without (p=0.002). CONCLUSIONS Mild cognitive impairment predicts short-term outcomes in HF, independent of clinical and non-clinical factors.

Abstract
BACKGROUND Coronary artery disease and left ventricular hypertrophy are prevalent in the chronic kidney disease (CKD) and renal transplant (RT) population. Advances in cardiovascular magnetic resonance (CMR) with blood oxygen level-dependent (BOLD) technique provides capability to assess myocardial oxygenation as a measure of ischemia. We hypothesized that the myocardial oxygenation response to stress would be impaired in CKD and RT patients. METHODS AND RESULTS Fifty-three subjects (23 subjects with CKD, 10 RT recipients, 10 hypertensive (HT) controls, and 10 normal controls without known coronary artery disease) underwent CMR scanning. All groups had cine and BOLD CMR at 3 T. The RT and HT groups also had late gadolinium CMR to assess infarction/replacement fibrosis. The CKD group underwent 2-dimensional echocardiography strain to assess fibrosis. Myocardial oxygenation was measured at rest and under stress with adenosine (140 μg/kg per minute) using BOLD signal intensity. A total of 2898 myocardial segments (1200 segments in CKD patients, 552 segments in RT, 480 segments in HT, and 666 segments in normal controls) were compared using linear mixed modeling. Diabetes mellitus (P=0.47) and hypertension (P=0.57) were similar between CKD, RT, and HT groups. The mean BOLD signal intensity change was significantly lower in the CKD and RT groups compared to HT controls and normal controls (-0.89±10.63% in CKD versus 5.66±7.87% in RT versus 15.54±9.58% in HT controls versus 16.19±11.11% in normal controls, P<0.0001). BOLD signal intensity change was associated with estimated glomerular filtration rate (β=0.16, 95% CI=0.10 to 0.22, P<0.0001). Left ventricular mass index and left ventricular septal wall diameter were similar between the CKD predialysis, RT, and HT groups. None of the CKD patients had impaired global longitudinal strain and none of the RT group had late gadolinium hyperenhancement. CONCLUSIONS Myocardial oxygenation response to stress is impaired in CKD patients and RT recipients without known coronary artery disease, and unlikely to be solely accounted for by the presence of diabetes mellitus, left ventricular hypertrophy, or myocardial scarring. The impaired myocardial oxygenation in CKD patients may be associated with declining renal function. Noncontrast BOLD CMR is a promising tool for detecting myocardial ischemia in the CKD population.

Abstract
Rapid intravenous (iv) infusion of 0.9% saline alters respiratory mechanics in healthy subjects. However, the relative cardiovascular and respiratory effects of bolus iv crystalloid vs. colloid are unknown. Six healthy male volunteers were given 30 ml/kg iv 0.9% saline, 4% albumin, and 5% glucose at a rate of 100 ml/min on 3 separate days in a double-blinded, randomized crossover study. Impulse oscillometry, spirometry, lung volumes, diffusing capacity (DLCO), and blood samples were measured before and after fluid administration. Lung ultrasound B-line score (indicating interstitial pulmonary edema) and Doppler echocardiography indices of cardiac preload were measured before, midway, immediately after, and 1 h after fluid administration. Infusion of 0.9% saline increased small airway resistance at 5 Hz (P = 0.04) and lung ultrasound B-line score (P = 0.01) without changes in Doppler echocardiography measures of preload. In contrast, 4% albumin increased DLCO, decreased lung volumes, and increased the Doppler echocardiography mitral E velocity (P = 0.001) and E-to-lateral/septal e' ratio, estimated blood volume, and N-terminal pro B-type natriuretic peptide (P = 0.01) but not lung ultrasound B-line score, consistent with increased pulmonary blood volume without interstitial pulmonary edema. There were no significant changes with 5% glucose. Plasma angiopoietin-2 concentration increased only after 0.9% saline (P = 0.001), suggesting an inflammatory mechanism associated with edema formation. In healthy subjects, 0.9% saline and 4% albumin have differential pulmonary effects not attributable to passive fluid filtration. This may reflect either different effects of these fluids on active signaling in the pulmonary circulation or a protective effect of albumin.

Abstract
BACKGROUND Myocardial ischemia is a major cause of death in chronic kidney disease (CKD) patients, which can be caused by either epicardial or microvascular coronary artery disease (CAD). Although renal transplantation improves survival, cardiovascular disease remains a major cause of mortality in post renal transplant recipients, including those with no significant epicardial CAD pre-transplant. We aim to utilize stress cardiovascular magnetic resonance (CMR) and MR coronary angiography (MRCA) to assess silent myocardial ischemia and epicardial CAD in renal transplant recipients. METHODS Forty-five subjects: twenty renal transplant (RT) with no known CAD, fifteen liver transplant (LT) controls without prior CKD and no known CAD, and ten hypertensive (HT) controls underwent stress perfusion CMR and MRCA. RESULTS A total of 1308 myocardial segments (576 of RT, 468 of LT, and 264 of HT) were compared using mixed linear modeling. Left ventricular mass index, septal diameter and presence of diabetes mellitus were similar between the groups. The mean transmural MPRI was significantly lower in the RT and LT groups compared to HT controls (1.19 ± 0.50 in RT versus 1.23 ± 0.36 in LT versus 2.04 ± 0.32 in HT controls, p < 0.0001), in the subepicardium (1.33 ± 0.57 in RT versus 1.30 ± 0.33 in LT versus 2.01 ± 0.30 in HT controls, p < 0.001), and in the subendocardium (1.19 ± 0.54 in RT versus 1.11 ± 0.31 in LT versus 1.85 ± 0.34 in HT controls, p < 0.0001). Seven (35%) RT and five (33%) LT had significant epicardial CAD compared to none in HT controls, p = 0.12. One RT and one LT had LGE suggesting sub-endocardial infarction. CONCLUSIONS RT recipients have impaired myocardial perfusion independent of LVH or diabetes mellitus. The impaired myocardial perfusion in RT is similar to LT without prior renal disease, thus unlikely related to previous CKD. It is not fully explained by the presence of significant epicardial CAD, and therefore most likely represents microvascular CAD.

Abstract
BACKGROUND Paravalvular aortic regurgitation (PAR) following transcatheter aortic valve implantation (TAVI) is well acknowledged. Despite improvements, echocardiographic measurement of PAR largely remains qualitative. Cardiovascular magnetic resonance (CMR) directly quantifies AR with accuracy and reproducibility. We compared CMR and transthoracic echocardiography (TTE) analysis of pre-operative and post-operative aortic regurgitation in patients undergoing both TAVI and surgical aortic valve replacement (AVR). METHODS Eighty-seven patients with severe aortic stenosis undergoing TAVI (56 patients) or AVR were recruited. CMR (1.5 T) and transthoracic echocardiography (TTE) were carried out pre-operatively and a median of 6 days post-operatively. The CMR protocol included regurgitant aortic flows using through-plane phase-contrast velocity. None/trivial, mild, moderate and severe AR by CMR was defined as ≤8%, 9-20%, 21-39%, >40% regurgitant fractions respectively. RESULTS Pre- and post-operative left ventricular ejection fraction (LVEF) was similar. Post-procedure aortic regurgitant fraction using CMR was higher in the TAVI group (TAVI 16 ± 13% vs. AVR 4 ± 4%, p < 0.01). Comparing CMR to TTE, 27 of 56 (48%) TAVI patients had PAR which was at least one grade more severe on CMR than TTE (Z = -4.56, p <0.001). Sensitivity analysis confirmed the difference in PAR grade between TTE and CMR in the TAVI group (Z = -4.49, p < 0.001). CONCLUSION When compared to CMR based quantitative analysis, TTE underestimated the degree of paravalvular aortic regurgitation. This underestimation may in part explain the findings of increased mortality associated with mild or greater AR by TTE in the PARTNER trial. Paravalvular aortic regurgitation post TAVI assessed as mild by TTE may in fact be more severe.

Abstract
Coronary artery disease is the leading cause of mortality and morbidity in the chronic kidney disease (CKD) population and often presents with atypical symptoms. Current diagnostic investigations of myocardial ischemia in CKD lack sensitivity and specificity or may have adverse effects. We present a case vignette and explore the challenges of diagnostic myocardial stress investigation in patients with CKD.

Abstract
BACKGROUND Chronic heart failure (CHF) following coronary artery ligation and myocardial infarction in the rat leads to a homeostatic reduction in surface tension with associated alveolar type II cell hyperplasia and increased surfactant content, which functionally compensates for pulmonary collagen deposition and increased tissue stiffness. To differentiate the effects on lung remodelling of the sudden rise in pulmonary microvascular pressure (Pmv) with myocardial infarction from its consequent chronic elevation, we examined a hypertensive model of CHF. METHODS Cardiopulmonary outcomes due to chronic pulmonary capillary hypertension were assessed at six and 15 weeks following abdominal aortic banding (AAB) in the rat. RESULTS At six weeks post-surgery, despite significantly elevated left ventricular end-diastolic pressure, myocardial hypertrophy and increased left ventricular internal circumference in AAB rats compared with sham operated controls (p≤0.003), lung weights and tissue composition remained unchanged, and lung compliance was normal. At 15 weeks post-surgery increased lung oedema was evident in AAB rats (p=0.002) without decreased lung compliance or evidence of tissue remodelling. CONCLUSION Despite chronically elevated Pmv, comparable to that resulting from past myocardial infarction (LVEDP>19mmHg), there is no evidence of pulmonary remodelling in the AAB model of CHF.

Abstract
AIMS Chronic heart failure leads to pulmonary vascular remodelling and thickening of the alveolar-capillary barrier. We examined whether this protective effect may slow resolution of pulmonary oedema consistent with decreased bi-directional fluid flux. METHODS AND RESULTS Seven weeks following left coronary artery ligation, we measured both fluid flux during an acute rise in left atrial pressure (n = 29) and intrinsic alveolar fluid clearance (n = 45) in the isolated rat lung. Chronic elevation of pulmonary microvascular pressure prevented pulmonary oedema and decreased lung compliance when left atrial pressure was raised to 20 cmH2O, and was associated with reduced expression of endothelial aquaporin 1 (P = 0.03). However, no other changes were found in mediators of fluid flux or cellular fluid channels. In isolated rat lungs, chronic LV dysfunction (LV end-diastolic pressure and infarct circumference) was also inversely related to alveolar fluid clearance (P ≤ 0.001). The rate of pulmonary oedema reabsorption was estimated by plasma volume expansion in eight patients with a previous clinical history of chronic heart failure and eight without, who presented with acute pulmonary oedema. Plasma volume expansion was reduced at 24 h in those with chronic heart failure (P = 0.03). CONCLUSIONS Chronic elevation of pulmonary microvascular pressure in CHF leads to decreased intrinsic bi-directional fluid flux at the alveolar-capillary barrier. This adaptive response defends against alveolar flooding, but may delay resolution of alveolar oedema.

Abstract
Chronic heart failure (CHF) leads to complex effects distant from the heart. As these changes may be reflected in the balance of systemic inflammatory and fibrotic immunomodulators we measured these potential biomarkers in ambulatory CHF patients. Using the New York Heart Association (NYHA; levels II-IV) functional classification, 30 CHF patients were compared with 21 age and gender matched controls. Peripheral blood levels of regulatory cytokines (TNF-α, TGF-β, KGF, IL-8, IL-10 and IL-12) and markers of cellular activation (CD11b, CD16, CD18, CD34, HLADR, CXCR1 and CCR5) were analysed by ELISA and flow cytometry, respectively. NYHA classification, which reflected increasing pulmonary microvascular pressure (E:E') but not ejection fraction, was positively associated with TGF-β and IL-10 (p≤0.03). Similarly, monocytes, as well as cell surface expression of the neutrophil adhesion molecule CD11b, and the macrophage complement receptor complex (CD11b/CD18), were increased in CHF patients (p≤0.03), while the chemokine receptor CXCR1 was decreased on cells of CHF patients. Twenty month follow-up of CHF subjects identified monocyte number as a powerful prognostic factor for cardio-pulmonary adverse events (p=0.001); however, no concurrent relationship with cellular activation marker expression was found. In subjects with CHF, monocytes, TGF-β, IL-10, CD11b/CD18 and CXCR1 expression in peripheral blood may act as novel biomarkers of immune activation and remodelling. Given the importance of dyspnea and the relationship of pulmonary microvascular pressure to the NYHA classification, we suggest these findings may reflect a contribution by the lung.

Abstract
Heart failure with normal ejection fraction (HFNEF), previously referred to as diastolic heart failure, has increased in prevalence as a cause of heart failure, now accounting for up to 50% of all cases. Contrary to initial evidence, the prognostic outlook in HFNEF may be similar to that of heart failure with reduced ejection fraction. According to current consensus statements, the diagnosis of HFNEF requires the demonstration of relatively preserved systolic left ventricular function and evidence of diastolic dysfunction. Noninvasive imaging techniques now permit evaluation of these parameters without need for cardiac catheterization in the large majority of patients. Echocardiography is the modality of choice in the evaluation of diastolic function but suffers from limitations in its assessment of systolic function. Cardiac magnetic resonance (CMR) imaging is the gold standard in the volumetric quantification of systolic function; however, it has limitations in its ability to characterize diastolic function. This report aims to review the strengths and weaknesses of both imaging modalities in the diagnosis of HFNEF. With regards to echocardiography, it will specifically describe limitations in measuring left ventricular ejection fraction, describe novel techniques to assess systolic function such as tissue velocity and strain analysis, and will review the measurements used in the evaluation of diastolic function. With respect to CMR, this review will highlight its value in the assessment of systolic left ventricular function, will review ancillary CMR findings that may support the diagnosis of HFNEF such as tissue characterization, and will provide a brief overview of CMR techniques to assess diastolic function. We propose that these 2 modalities may play a complementary role in the diagnosis of HFNEF. The importance of imaging in the diagnosis of HFNEF extends to both the individual patient and to clinical trials of therapies for this condition.

Abstract
RATIONALE Chronic elevation of pulmonary microvascular pressure in chronic heart failure results in compensatory changes in the lung that reduce alveolar fluid filtration and protect against pulmonary microvascular rupture. OBJECTIVES To determine whether these compensatory responses may have maladaptive effects on lung function. METHODS Six weeks after myocardial infarction (chronic heart failure model) rat lung composition, both gross and histologic; air and saline mechanics; surfactant production; and immunological mediators were examined. MEASUREMENTS AND MAIN RESULTS An increase in dry lung weight, due to increased insoluble protein, lipid and cellular infiltrate, without pulmonary edema was found. Despite this, both forced impedance and air pressure-volume mechanics were normal. However, there was increased tissue stiffness in the absence of surface tension (saline pressure-volume curve) with a concurrent increase in both surfactant content and alveolar type II cell numbers, suggesting a novel homeostatic phenomenon. CONCLUSIONS These studies suggest a compensatory reduction in pulmonary surface tension that attenuates the effect of lung parenchymal remodeling on lung mechanics, hence work of breathing.

Abstract
AIMS To determine whether the degree of untwisting of the apex in early diastole is related to established parameters of diastolic function. METHODS AND RESULTS Data from 71 hospital inpatients with preserved left ventricular systolic function who underwent standard two-dimensional echocardiography was analysed using an off-line speckle tracking software package. Early diastolic mitral inflow velocity (e), mitral septal annular tissue Doppler velocity (e'), and the rate of early diastolic apical untwist in degrees per second (rotR) from a parasternal short-axis view of the apex were all measured. Of the 71 patients, 14 had normal diastolic function, 25 had an abnormal relaxation pattern, 27 had a pseudonormalized pattern, and 5 had a restrictive pattern as defined by standard echocardiography criteria. Both e' and the ratio of e:e' correlated with the rate (speed) of early diastolic apical untwist (rotR) (P < 0.001 for both). CONCLUSION This non-invasive assessment of apical diastolic untwist is related to established echocardiographic measures of diastolic function and may illustrate the importance of a ventricular suction effect in varying left ventricular filling states.

Abstract
Recently, it has been demonstrated that high-resolution transthoracic echocardiography (HRTTE) is able to detect differences in the wall thickness of the left anterior descending coronary artery (LAD) between patients with coronary artery disease (CAD) and normal volunteers. The aim of this study was to further validate this technique. One hundred ten volunteers, 58 patients with angiographically proved CAD and 52 control subjects, underwent assessments of their LADs using HRTTE. Anterior and posterior wall thicknesses differed between subjects in the CAD group and controls (1.9 +/- 0.6 vs 1.2 +/- 0.3 mm, p <0.001, and 1.8 +/- 0.5 vs 1.2 +/- 0.3 mm, p <0.001, respectively). External LAD diameter was also greater in subjects in the CAD group compared with controls (5.2 +/- 1.9 vs 4.4 +/- 0.9 mm, respectively, p = 0.01). However, there was no difference in luminal diameter between subjects in the CAD group and the controls (1.9 +/- 0.9 vs 2.1 +/- 0.8 mm, respectively, p = 0.3). In conclusion, HRTTE demonstrated that LAD wall thicknesses and external diameters in patients with CAD were significantly larger than in normal volunteers. Luminal diameter, however, was maintained in the 2 groups, indicating that subjects in the CAD group had undergone positive remodeling at the site measured. This objectively visualized evidence of coronary atherosclerosis with HRTTE would likely be undetected during coronary angiography.

Abstract
OBJECTIVES The study objective was to determine the effects of salbutamol and nitroglycerin (NTG) on the luminal diameter of the left anterior descending (LAD) coronary artery, as measured noninvasively by the novel technique of high-resolution transthoracic echocardiography (HRTTE). BACKGROUND Invasive studies of the coronary arteries have demonstrated vasodilatation by salbutamol and NTG. By using a novel technique of HRTTE, combined with assessment of augmentation index (AIx, a marker of peripheral arterial stiffness) by means of applanation tonometry from the radial artery (pulse wave analysis), we studied the vasomotion of the proximal LAD in healthy volunteers. METHODS Nineteen male subjects (age 31 +/- 5 years, mean +/- standard deviation) underwent HRTTE measurement of the wall thickness, luminal diameter, and external diameter of the proximal LAD, and AIx at baseline and 5, 10, 15, and 20 minutes after administration of inhaled salbutamol (400 microg) and, after return to baseline, sublingual NTG (300 microg). RESULTS Salbutamol induced a 44% +/- 28% increase in LAD luminal diameter (2.8 +/- 0.8 mm to 3.7 +/- 0.9 mm, P < .001) and a reduction in AIx (-13.4% +/- 6.6%, P < .001). NTG induced greater changes in both parameters (60% +/- 30% increase in luminal diameter from baseline, 2.7 +/- 0.9 mm to 4.4 +/- 1.1 mm, P < .001; and reduction in AIx -24.1% +/- 8.2%, P < .001). Changes in LAD diameter and AIx were related after both salbutamol (r = -0.53, P = .02) and NTG (r = -0.57, P = .01). No significant change was detected in wall thickness. CONCLUSION HRTTE is able to detect the LAD coronary artery vasodilating effects of NTG and salbutamol and correlates with peripheral vascular reactivity to these vasodilators. This approach provides a useful tool for the noninvasive assessment of coronary vasoreactivity.
