Abstract
OBJECTIVES To investigate whether phase angle (PhA) measured by bioelectrical impedance analysis (BIA) and frailty are associated with the outcomes of critical illnesses. DESIGN A single-center prospective cohort study. SETTING Medical intensive care unit (ICU) in Seoul National University Hospital, Seoul, Republic of Korea. PARTICIPANTS 97 patients who were admitted to the medical ICU. MEASUREMENTS On admission, PhA was measured by BIA, and frailty was assessed by the Korean Modified Barthel Index (KMBI) scoring system. Patients were classified according to PhA and KMBI scores, and their impact on the outcomes of critical illnesses was evaluated. RESULTS The patients' mean age was 62.4 ± 16.4 years, and 56 of the patients (57.7%) were men. Having a high PhA above 3.5 at the time of ICU admission was associated with lower in-hospital mortality (adjusted OR 0.42, p = .042), and a shorter duration of ICU stay (5.6 days vs. 9.8 days, p = .016) compared to those with a low PhA. Other indices measured by BIA were not significantly associated with outcomes of critical illnesses. Frailty (KMBI > 60) was associated with more mechanical ventilation days (2.3 days vs. 7.1 days; p = .018). CONCLUSION Both PhA and frailty are important prognostic factors predicting the outcomes of critical illnesses. Low PhA scores were associated with increased mortality and a longer duration of ICU stay, and frailty was associated with more mechanical ventilation days.

Abstract
Introduction Prostate cancer remains the 3rd leading cause of cancer-related mortality in Canadian men, and yet screening for prostate cancer continues to be controversial because the majority of men diagnosed with prostate cancer do not die of the disease. It also remains uncertain whether treatment of cases that can be treated with curative intent alters the mortality rate. There are very few studies describing the presenting stage, risk groups, and survival after diagnosis for men dying of prostate cancer in the literature. In this study, we explored these characteristics for all men who died of prostate cancer in British Columbia between 2013 and 2015. Methods The population-based BC Cancer databases were used to identify all patients diagnosed between January 2013 and December 2015 who died of prostate cancer. Patient, tumour, and treatment characteristics were collected, and the risk grouping for each tumour was determined. The proportion of cases in each risk group at the time of diagnosis was determined. Survival time from diagnosis to death was calculated for all patients and for each risk group using the Kaplan-Meier method. Results A total of 1256 patients died of prostate cancer. Of patients who presented with metastatic disease, 57.2% presented with a Gleason score of 8 or more, compared with only 35.7% of patients who presented with nonmetastatic disease (p < 0.0001). The presenting stage and risk group of those dying of prostate cancer were as follows: 32% metastatic disease, 3% regional (defined as node-positive), 39% localized high risk, 9% localized intermediate risk, 4% localized low risk, 6% localized not otherwise specified, and 7% unknown. Therefore, 80.3% of those with a known risk group presented with either localized high-risk, regional, or metastatic disease at diagnosis. The median survival times from diagnosis to death were 12 years for localized low-risk, 10 years for localized intermediate-risk, 6.5 years for localized high-risk, 4 years for regional, and 1.7 years for metastatic disease at diagnosis. Conclusions This population-based analysis demonstrates that patients with localized high-risk, regional, or metastatic disease at diagnosis constitute the overwhelming majority of patients who die of prostate cancer in British Columbia. Unless these disease states can reliably be identified at an earlier low- or intermediate-risk localized state in the future, it is unlikely that treatment of localized low- and intermediate-risk cancer will have an impact on survival. Furthermore, patients with de novo metastatic disease had identifiable risk factors of a higher prostate-specific antigen and Gleason score. Further studies are required to confirm these results.

Abstract
Background:In the absence of evidence-based treatment guidelines, medication use in SLE is highly variable. Low rates of remission and lupus low disease activity state (LLDAS) suggest that suboptimal responses to standard medications, which include glucocorticoids (GC), anti-malarial (AM) drugs and immunosuppressive (IS) agents, are common. Understanding the utility of current medications will facilitate the selection of patients for advanced therapies as they emerge.Objectives:To examine medication use patterns in a large multicentre SLE cohort.Methods:We used 2013-18 data from the Asia Pacific Lupus Collaboration (APLC) cohort in which disease activity (SLEDAI-2K) and medication details were captured at every visit. LLDAS was defined as in Golderet al., 2019 (1). We examined the use of medication (med) categories (GC &/or AM &/or IS) by SLE disease activity and LLDAS at the visit level. Additionally, we performed Cox regression analyses to determine the time-to-discontinuation of meds stratified by SLE disease activity, ranked by time-adjusted mean SLEDAI-2K, and by percent-time spent in LLDAS.Results:We analysed data from 19,804 visits of 2,860 patients. We observed 8 med categories: no meds; GC, AM or IS only; GC+AM; GC+IS; AM+IS and GC+AM+IS (triple therapy). Triple therapy was the most frequent med pattern (32%); single agents were used in 21% of visits and biologicals in only 3%. Among visits where SLEDAI-2K was ≥10, triple therapy was used in 46%, with median [IQR] GC dose 10 [6, 24] mg/day; in contrast, among visits with SLEDAI-2K≤4 triple therapy was used in 28% (p<0.01). Patients in LLDAS received less combination therapy than those who were not in LLDAS.Med persistence (survival analysis) varied widely, with lowest survivals for IS. Patients with time-adjusted mean SLEDAI-2K ≥10 had lower discontinuation of GC and higher discontinuation of IS including azathioprine, leflunomide and cyclosporine (Table 1). In contrast, increased time in LLDAS was associated with reduced discontinuation of AM and azathioprine.GCAMISMPhMPhAAZAMTXCyALEFOverall med survival, days to 25% discontinuation (95%CI)1048(938, 1197)1267(1113, 1428)175(175, 182)387(252, 756)409(350, 476)525(219, 686)268(182, 350)329(190, 524)Univariable associations,HR (95% CI) p-valueDisease activity≤41.001.001.001.001.001.001.001.00>4 & <100.69 (0.56,0.84)p<0.0011.15 (0.92,1.44)0.20.92 (0.80,1.05)0.21.37 (0.78,2.42)0.31.16 (0.97,1.39)0.111.11 (0.72,1.71)0.61.26 (0.90,1.77) 0.181.88 (1.07,3.30) 0.03≥100.65 (0.35,1.21) 0.181.56 (0.94,2.59) 0.080.84 (0.45,1.57)0.61.92 (0.80,4.63)0.142.69 (1.86,3.91) p<0.0011.85 (0.92,3.71) 0.082.66 (1.36,5.21) 0.0041.62 (1.13,2.32)0.009LLDAS<50%1.001.001.001.001.001.001.001.00≥50%1.30 (1.09, 1.55)0.0030.67 (0.54, 0.84)<0.0011.22 (1.08, 1.40)0.0020.83 (0.44,1.57)0.60.83 (0.69, 1.00)0.0540.70 (0.46, 1.07)0.101.29 (0.92, 1.83)0.140.43 (1.5, 1.25)0.12Conclusion:In a large multicentre SLE cohort, most patients were receiving combination treatment. AM treatment survival was high and associated with low disease activity, GC survival was high and associated with high disease activity, while IS survival was low. Patients with high disease activity received more medication combinations but had reduced IS survival. These data suggest ongoing unmet need for improved medications for treatment of SLE.Reference:Golder, V., et al Lancet Rheum. 2019 1(2):e95-102Disclosure of Interests:Rangi Kandane-Rathnayake Grant/research support from: The APLC has received financial (non-restricted educational) grants from AstraZeneca, Bristol Myers Squibb, GlaxoSmithKline, Janssen, EMD Serono, Eli Lilly and UCB for the LLDAS Validation Study., Worawit Louthrenoo: None declared, Shue Fen Luo: None declared, Yeong-Jian Wu Consultant of: Pfizer, Lilly, Novartis, Abbvie, Roche, Speakers bureau: Lilly, Novartis, Yi-Hsing Chen Grant/research support from: Taiwan Ministry of Science and Technology, Taiwan Department of Health, Taichung Veterans General Hospital, National Yang-Ming University, GSK, Pfizer, BMS., Consultant of: Pfizer, Novartis, Abbvie, Johnson & Johnson, BMS, Roche, Lilly, GSK, Astra& Zeneca, Sanofi, MSD, Guigai, Astellas, Inova Diagnostics, UCB, Agnitio Science Technology, United Biopharma, Thermo Fisher, Gilead., Paid instructor for: Pfizer, Novartis, Johnson & Johnson, Roche, Lilly, Astra& Zeneca, Sanofi, Astellas, Agnitio Science Technology, United Biopharma., Speakers bureau: Pfizer, Novartis, Abbvie, Johnson & Johnson, BMS, Roche, Lilly, GSK, Astra& Zeneca, Sanofi, MSD, Guigai, Astellas, Inova Diagnostics, UCB, Agnitio Science Technology, United Biopharma, Thermo Fisher, Gilead., Vera Golder: None declared, Aisha Lateef: None declared, Jiacai Cho: None declared, Sandra Navarra Speakers bureau: Astellas, Novartis, Pfizer, Johnson & Johnson, Abbvie, Leonid Zamora: None declared, Laniyati Hamijoyo Speakers bureau: Pfizer, Novartis, Tanabe, Abbot, Dexa Medica, Roche, Sargunan Sockalingam: None declared, Yuan An: None declared, Zhanguo Li: None declared, Yasuhiro Katsumata: None declared, masayoshi harigai Grant/research support from: AbbVie Japan GK, Ayumi Pharmaceutical Co., Bristol Myers Squibb Co., Ltd., Eisai Co., Ltd., Mitsubishi Tanabe Pharma Co., Nippon Kayaku Co., Ltd., and Teijin Pharma Ltd.

Abstract
Background:Anti-carbamylated protein antibody (anti-carp) positivity has been associated with poorer outcomes in Western cohorts of early rheumatoid arthritis; however, it is unknown if this applies to Asians.Objectives:We determined whether anti-carp predicted DAS28-remission, disability and radiographic progression in a multi-ethnic Asian ERA cohort.Methods:Patients with physician diagnosed ERA (symptom duration ≤1 year) were recruited from the Singapore Early Arthritis Cohort (n= 317) by convenience sampling. Serum anti-carp was measured cross-sectionally using a commercial ELISA (SincereBio). The test was repeated in 40 healthy individuals to establish the optimal sensitivity and specificity for the diagnosis of RA via a receiver operating curve. Disease activity (DAS28-ESR or DAS28-CRP) was recorded at baseline, 3, 6 and 12 months. Two independent accessors quantified the radiographic damage at baseline and at follow-up using the modified Sharp van der Heijde score (mSS). We used multivariable logistic regression to determine whether anti-carp predicted the following outcomes; (i) DAS-28 remission at 12 months, (ii) any disability (mHAQ>0) at 12 months and (iii) radiographic progression (any increase in the mSS). In each regression model, we chose covariates known to influence the dependent variable in our cohort or from literature.Results:One hundred patients were recruited, of mean age (SD) 49.8 (12.5) years, median (IQR) disease duration 10.2 (6.9-15.1) weeks at cohort entry and baseline median DAS-28 4.5 (2.9-5.9) (Table 1). The anti-carp assay was performed after a median (IQR) disease duration of 2.24 (1.82-3.14) years. 93 patients had baseline hand radiographs and 66 had follow-up hand radiographs after ≥ 12 months. Receiver operating characteristics curve yielded optimal sensitivity (95%) and specificity (60%) for the diagnosis of RA at 1.60OD. Therefore, 60 patients were anti-carp positive and 35 patients (37.2%) were positive for RF, ACPA and anti-carp (Figure 1). Anti-carp positivity independently predicted DAS28-remission at 12 months (OR 3.41, 95% CI 1.08-10.7,p=0.04) (Table 2). Anti-carp positivity did not predict disability at 12 months (OR 0.61, 95% CI 0.18-2.07,p=0.43) or radiographic progression (OR 0.23, 95% CI 0.03-2.03,p=0.18).Table 1.Predictors of DAS28-remission at 12 monthsVariableN (%)Univariable Logistic RegressionMultivariable Logistic RegressionORpOR (CI)SEpAnti-carp60 (60)3.0 (1.31−6.88)0.013.41 (1.08−10.7)1.990.04SerologyRF and ACPA negative31 (33.0)RefEither RF or ACPA positive11 (11.7)0.99 (0.25−3.93)0.991.10 (0.17−7.04)1.040.92RF and ACPA positive52 (55.3)1.12 (0.45−2.75)0.800.89 (0.28−2.81)0.520.84Baseline DAS28Remission17 (17.4)RefLow DA10 (10.2)0.50 (0.05−4.67)0.540.13 (0.01−1.67)0.170.12Mod DA32 (32.7)0.29 (0.05−1.65)0.160.10 (0.02−0.68)0.100.02High DA39 (39.8)0.18 (0.04−0.90)0.040.06 (0.01−0.41)0.06<0.01Combination csDMARDs or biologic DMARD74 (74)1.13 (0.46−2.76)0.801.97 (0.58−6.67)1.230.28Radiographic damage at baseline11 (20)1.79 (0.65−4.95)0.261.27 (0.33-4.95)0.880.73Tertiary education23 (38.3)0.77 (0.34-1.77)0.540.42 (0.12-1.45)0.270.17EthnicityChinese42 (70)RefMalay39 (68.4)0.61 (0.22-1.71)0.350.56 (0.14-2.25)0.400.41Indian8 (13.3)0.60 (0.20-1.77)0.350.79 (0.20-3.13)0.560.74Females46 (76.7)0.43 (0.17-1.11)0.080.48 (0.13-1.85)0.330.29Conclusion:Contrary to previous studies done on Western cohorts where anti-carp predicted worse outcomes, anti-carp positivity predicted DAS28-remission at 12 months in our multi-ethnic Asian cohort.

Abstract
BACKGROUND Deregulation of the PI3K signalling pathway is frequent in squamous cell carcinoma of the head and neck (SCCHN) and may be implicated in radioresistance. We report on the results from a phase I 3 + 3 dose escalation study of alpelisib, a class I α-specific PI3K inhibitor in combination with concurrent cisplatin-based chemoradiation (CRT) in patients with locoregionally advanced SCCHN (LA-SCCHN). METHODS Eligible patients had previously untreated LA-SCCHN and were candidates for CRT. The primary objective was to evaluate safety and determine the recommended phase II dose (RP2D). Alpelisib was given orally once daily at two dose levels: 200 mg and 250 mg. CRT consisted of cisplatin 100 mg/m2 IV every three weeks and standard fractionation radiotherapy (IMRT) 70 Gy in 35 fractions. RESULTS Nine patients were enrolled (six alpelisib 200 mg, three 250 mg). Oropharynx was the primary site in all patients (seven p16-positive; five T1-2N2M0, four T3-4N2-3M0 [AJCC 7th edition]). All patients completed CRT within seven weeks. Grade 3 alpelisib-related toxicities occurred in four patients. No dose-limiting toxicity (DLT) was observed at 200 mg among three DLT-evaluable patients. Two of two DLT-evaluable patients treated at 250 mg experienced DLTs (inability to complete ≥75% alpelisib secondary to radiation dermatitis and febrile neutropenia). Thus, RP2D was declared at 200 mg. After median follow-up of 39.7 months, two patients developed pulmonary metastases despite locoregional control. Three-year overall survival was 77.8% (95% CI 36.5%-93.9%). CONCLUSION Alpelisib at 200 mg has a manageable safety profile in combination with cisplatin-based CRT in LA-SCCHN.

Abstract
Background and Objectives: The personal distress associated with caring for a family member has been well documented; however, questions about the burden of caregiving for centenarians and cross-national differences in the caregiving context, remain unanswered.Research Design and Methods: This study includes reports by caregivers of 538 near-centenarians and centenarians in the U.S. and Japan: 234 from the Georgia Centenarian Study and 304 from the Tokyo Centenarian Study. Basic descriptive and multivariate regression analyses were conducted. Mean levels of caregiver burden and near-centenarian and centenarians' characteristics (as predictors) for caregiver burden were compared between the U.S. and Japan. The near-centenarian and centenarians' functional capacity and personality were assessed as predictors.Results: Differential predictive patterns in caregiver burden were found in the two groups. In the U.S., near-centenarian and centenarians' agreeableness and conscientiousness were negatively associated with caregiver burden; whereas the near-centenarian and centenarians' neuroticism and number of diseases were positively associated with caregiver burden. In Japan, the near-centenarian and centenarians' activities of daily living, openness, and agreeableness were negatively associated with caregiving burden. Interaction effects between functional capacity and personality, on caregiver burden were observed only in the U.S. In the U.S., higher levels of agreeableness and openness significantly changed the level of caregiver burden associated with vision problems and a greater number of diseases.Discussion and Implications: Cross-national comparative predictors of caregiving burden between the two countries emphasized that caring for centenarians should be understood in the caregiving context, as well as the social context.

Abstract
BACKGROUND AND PURPOSE The use of invasive cerebral angiography with CTA for active treatment of patients with suspected ischemic strokes has been increasing recently. This study aimed to identify the incidence of postcontrast acute kidney injury using baseline renal function when CTA and cerebral angiography were performed sequentially. MATERIALS AND METHODS This retrospective observational study evaluated adults (18 years of age or older) with ischemic stroke who underwent CTA and cerebral angiography sequentially between 2010 and 2018. The incidence of postcontrast acute kidney injury was determined using the baseline estimated glomerular filtration rate. The value of the baseline estimated glomerular filtration rate at which the occurrence of postcontrast acute kidney injury increased was also determined. RESULTS Postcontrast acute kidney injury occurred in 57/601 (9.5%) patients. Those with a baseline estimated glomerular filtration rate of <30 mL/min/1.73 m2 showed a higher incidence of acute kidney injury. Age, chronic kidney disease, medication (nonsteroidal anti-inflammatory drugs, angiotensin-converting enzyme inhibitors, angiotensin II receptor blockers, β blockers, statins, and insulin) use following contrast media exposure, and serum albumin affected the incidence of postcontrast acute kidney injury. The incidence of postcontrast acute kidney injury increased when the baseline estimated glomerular filtration rate was <43 mL/min/1.73 m2. CONCLUSIONS Patients with low baseline renal function had the highest incidence of postcontrast acute kidney injury after CTA and cerebral angiography, but no fatal adverse effects were documented. Thus, patients suspected of having a stroke should be actively managed with respect to neurovascular function.

Abstract
Abstract
Background
The assessment of diastolic function is still challenging in the setting of heart failure (HF). We tested the hypothesis that applying a machine learning algorithm would detect heterogeneity in diastolic function and improve risk stratification in HF population.
Methods
This study included consecutive 279 patients with clinically stable HF referred for echocardiographic assessment, for whom diastolic function variables were measured according to the current guidelines. Cluster analysis, an unsupervised machine learning algorithm, was undertaken on these variables to form homogeneous groups of patients with similar profiles of the variables. Sequential Cox models paralleling the clinical sequence of HF assessment were used to elucidate the benefit of cluster-based classification over guidelines-based classification. The primary endpoint was a hospitalization for worsening HF.
Results
Cluster analysis identified 3 clusters with distinct properties of diastolic function that shared similarities with guidelines-based classification. The clusters were associated with brain natriuretic peptide level (p < 0.001, figure A). During follow-up period of 2.6 ± 2.0 years, 62 patients (22%) experienced the primary endpoint. Cluster-based classification exhibited a significant prognostic value (c2 = 20.3, p < 0.001, figure B), independent from and incremental to an established clinical risk score for HF (MAGGIC score) and left ventricular end-diastolic volume (hazard ratio = 1.677, p = 0.017, model c2: from 47.5 to 54.1, p = 0.015, figure D). Although guideline-based classification showed a significant prognostic value (c2 = 13.1, p = 0.001, figure C), it did not significantly improve overall prognostication from the baseline (model c2: from 47.5 to 49.9, p = 0.199, figure D).
Conclusion
Machine learning techniques help grading diastolic function and stratifying the risk for decompensation in HF.

Abstract
Abstract
Background
Pulmonary hypertension (PH) is prevalent and is associated with adverse outcomes in heart failure. The pathophysiology of PH is heterogeneous, including pre-capillary PH and combined pre- and post-capillary PH. The latter PH has been reported in experimental studies to cause wave reflection in pulmonary circulation, putting additional burden on right ventricle. This study tested the hypothesis that separating wave reflection would enhance risk stratification in heart failure.
Methods
This study included 152 patients with clinical stable heart failure associated with PH who were referred to echocardiography for hemodynamic assessment (age = 72 ± 13 years old, ejection fraction = 49 ± 21%). Pulmonary arterial wave reflection was characterised by separating PA pressure waveform into forward (Pf) and backward pressure (Pb) waves, based on the concept of wave intensity. PA pressure waveform was estimated from continuous Doppler tracing of tricuspid regurgitation. Flow velocity was measured by pulse Doppler at right ventricular outflow tract. Outcome data was obtained by reviewing medical charts. The endpoint was hospitalization for worsening heart failure (WHF).
Results
Figure A compares PA pressure waveforms (total and separated waves) obtained from 2 patients with and without WHF event. The patient with event had higher total pressure associated with late peak than the patient without event. Pb appeared later than Pf; it was markedly higher in the patient with event than the patient without event, although Pf was similar between both patients. Kaplan-Meier analysis demonstrated a significant separation of survival curves stratified by Pb (chi-square = 25.1, p < 0.001, figure B). During follow-up period of 1.5 ± 1.8 years, 65 patients (43%) experienced the endpoint. Sequential Cox analysis revealed that PASP remained significant after adjusted for left ventricular ejection fraction and E/e’ (hazard ratio = 1.017, p = 0.019). Pb also remained significant after the same adjustment (hazard ratio = 1.066, p = 0.003); the addition of Pb to a baseline model resulted in greater increase in predictive power than the addition of PASP (model chi-square: from 27.4 (baseline), to 37.6 (p = 0.004) for Pb, to 31.6 (p = 0.027) for PASP, figure C)
Conclusions
Pressure wave reflection in pulmonary artery is associated with early decompensation in heart failure.

Abstract
Abstract
Background
Grading the severity of aortic stenosis (AS) is challenging, since there is a discrepancy between aortic valve area (AVA) and mean pressure gradient (mPG). Arotic valve resistance (RES) has been proposed as a usuful descriptor of AS severity, but it is not commonly used for clinical decision-making, because its robust validation of clinical-outcome efficacy is lacking. This study aimed to investigate whether RES holds an incremental value for risk-stratifying AS.
Methods
This study recuited 565 AS patients (AVA < 1.5cm²) referred to echocardiography for valve assessment. The patients were divided into three different groups, according to the guidelines: high-gradient AS (HG-AS, mPG≥40mmHg, n = 157), low-gradient AS (LG-AS, mPG < 40mmHg + AVA ≤ 1.0cm², n = 155) and moderate AS (Mod-AS, mPG < 40mmHg + AVA > 1.0cm², n = 253). RES was calculated from Doppler measurement of mPG and stoke volume. The diagnositic cutoff point for RES was determined at 190 dynes × s×cm-5 by substituting AVA = 1.0cm² and mPG = 40mmHg into the definition formula of RES and Gorlin formula. The patients were followed up for 2 years. The endpoint was a composite of cardiac death, hospitalization for heart failure and aortic valve replacement necessitated by the development of AS-related symptoms.
Result
Kaplan-Meier analyses showed that LG-AS exhibited an intermediate outcome between HG-AS and Mod-AS (event-free survival at 2 years = 20.9% for HG-AS, 59.7% for LG-AS, 89.9% for Mod-AS, p < 0.001, figure A). When LG-AS was stratified by RES, the survival curves showed a significant separation (event-free survival at 2 years = 35.3% for high RES, 70.7% for low RES, p < 0.001, figure B). This trend persisted even when analysed separately for norml (stroke volume index > 35ml/m²) and low (stroke volume index ≤ 35ml/m²) flow state ((normal flow) event-free survival at 2 years = 38.7% for high RES, 70.4% for low RES, p = 0.023, figure C; (low flow) event-free survival at 2 years = 26.7% for high RES, 74.6% for low RES, p < 0.001, figure D).
Conclusion
This study confirmed the clinical efficacy of RES for risk-stratifying LG-AS patients.

Abstract
Abstract
Background
Blood flows through healthy hearts form optimal flow structures; they store flow kinetic energy (KE) that can be used for ejection. In contrast, in failing hearts, intracardiac flows become disorganized so that they may be energetically inefficient. However, it remained unknown whether left ventricular (LV) flow energetics prognosticates in heart failure.
Methods
This study included 61 patients with dilated cardiomyopathy (DCM). The temporal change in KE during early diastole (ED), atrial contraction (AC) and isovolumic contraction (IVC) was measured using Vector Flow Mapping particle tracking (Hitachi, figure top). LV inflow (total flow) were divided, based on whether they were ejected (direct flow, DF) or stayed in LV (retained flow, RF) in the following systole. KE of DF can be made use of for ejection, whereas KE of RF is supposed to be wasted. Diastolic function was graded, according to current EACVI/ASE guidelines. The patients were followed up for three years. Primary endpoint was hospitalization for worsening heart failure (WHF).
Results
12 patients had hospitalizations for WHF in the follow-up period. KE of total flow did not show any significant difference through the cardiac cycle between patients with and without WHF. KE of DF was slightly, but not significantly, smaller (ED: p = 0.252, AC: p = 0.119, IVC: p = 0.122), and KE of RF was slightly, but not significantly, larger (ED: p = 0.971, AC: p = 0.085, IVC: p = 0.134) in patients with WHF than those without events. The ratio of DF and RF (DF/RF ratio) showed significant differences between these two groups, especially from AC through IVC (figure, bottom-left). Cox proportional hazard analyses demonstrated that DF/RF ratio during IVC showed a significant correlation with clinical outcomes (p = 0.033, hazard ratio = 0.067). It remained significant even after adjusted for diastolic function grade (p = 0.046, hazard ratio = 0.074). Kaplan-Meier analysis confirmed the above results (figure, bottom-right). Conclusion: Efficiency of KE recruitment for LV ejection during IVC is associated with clinical outcomes in DCM.
