Prognostic Value of Objective Social Isolation and Loneliness in Older Patients With Heart Failure: Subanalysis of FRAGILE-HF and Kitasato Cohort. J Am Heart Assoc 2024; 13:e032716. [PMID: 38726923 DOI: 10.1161/jaha.123.032716] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/18/2023] [Accepted: 04/15/2024] [Indexed: 05/22/2024]
Abstract
BACKGROUND Social factors encompass a broad spectrum of nonmedical factors, including objective (social isolation [SI]) and perceived (loneliness) conditions. Although social factors have attracted considerable research attention, information regarding their impact on patients with heart failure is scarce. We aimed to investigate the prognostic impact of objective SI and loneliness in older patients with heart failure. METHODS AND RESULTS This study was conducted using the FRAGILE-HF (Prevalence and Prognostic Value of Physical and Social Frailty in Geriatric Patients Hospitalized for Heart Failure; derivation cohort) and Kitasato cohorts (validation cohort), which included hospitalized patients with heart failure aged ≥65 years. Objective SI and loneliness were defined using the Japanese version of Lubben Social Network Scale-6 and diagnosed when the total score for objective and perceived questions on the Lubben Social Network Scale-6 was below the median in the FRAGILE-HF. The primary outcome was 1-year death. Overall, 1232 and 405 patients in the FRAGILE-HF and Kitasato cohorts, respectively, were analyzed. Objective SI and loneliness were observed in 57.8% and 51.4% of patients in the FRAGILE-HF and 55.4% and 46.2% of those in the Kitasato cohort, respectively. During the 1-year follow-up, 149 and 31 patients died in the FRAGILE-HF and Kitasato cohorts, respectively. Cox proportional hazard analysis revealed that objective SI, but not loneliness, was significantly associated with 1-year death after adjustment for conventional risk factors in the FRAGILE-HF. These findings were consistent with the validation cohort. CONCLUSIONS Objective SI assessed using the Lubben Social Network Scale-6 may be a prognostic indicator in older patients with heart failure. Given the lack of established SI assessment methods in this population, further research is required to refine such methods.

Abstract
BACKGROUND Although frailty is strongly associated with mortality in patients with heart failure (HF), the risk of which specific cause of death is associated with being complicated with frailty is unclear. We aimed to clarify the association between multidomain frailty and the causes of death in elderly patients hospitalized with HF. METHODS We analyzed data from the FRAGILE-HF cohort, where patients aged 65 years and older, hospitalized with HF, were prospectively registered between 2016 and 2018 in 15 Japanese hospitals before discharge and followed up for 2 years. All patients were assessed for physical, social, and cognitive dysfunction, and categorized into 3 groups based on their number of frailty domains (FDs, 0-1, 2, and 3). Kaplan-Meier survival analysis was used to evaluate the association between the number of FDs and all-cause mortality, whereas Fine-Gray competing risk regression analysis was used for assessing the impact on cause-specific mortality. RESULTS We analyzed 1181 patients with HF (81 years old in median, 57.4% were male), 530 (44.9%), 437 (37.0%), and 214 (18.1%) of whom were categorized into the FD 0 to 1, FD 2, and FD 3 groups, respectively. During the 2-year follow-up, 240 deaths were observed (99 HF deaths, 34 cardiovascular deaths, and 107 noncardiovascular deaths), and an increase in the number of FD was significantly associated with mortality (Log-rank: P<0.001). The Fine-Gray competing risk analysis adjusted for age and sex showed that FDs 2 (subdistribution hazard ratio, 1.77 [95% CI, 1.11-2.81]) and 3 (2.78, [95% CI, 1.69-4.59]) groups were associated with higher incidence of noncardiovascular death but not with HF and other cardiovascular deaths. CONCLUSIONS Although multidomain frailty is strongly associated with mortality in older patients with HF, it is mostly attributable to noncardiovascular death and not cardiovascular death, including HF death.

Bendopnea prevalence and prognostic value in older patients with heart failure: FRAGILE-HF-SONIC-HF post hoc analysis. Eur J Prev Cardiol 2024:zwae128. [PMID: 38573843 DOI: 10.1093/eurjpc/zwae128] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/12/2023] [Revised: 02/27/2024] [Accepted: 04/03/2024] [Indexed: 04/06/2024]
Abstract
AIMS This study aimed to investigate the prevalence, clinical characteristics, and prognostic value of bendopnea in older patients hospitalized for heart failure. METHODS This post hoc analysis was performed using two prospective, multicenter, observational studies: the FRAGILE-HF (main cohort) and SONIC-HF (validation cohort) cohorts. Patients were categorized based on the presence of bendopnea, which was evaluated before discharge. The primary endpoint was 2-year all-cause mortality after discharge. RESULTS Among the 1,243 patients (median age, 81 years; 57.2% male) in the FRAGILE-HF cohort and 225 (median age, 79 years; 58.2% men) in the SONIC-HF cohort, bendopnea was observed in 31 (2.5%) and 10 (4.4%) patients, respectively. Over a 2-year follow-up period, all-cause death occurred in 20.8% and 21.9% of the patients in the FRAGILE-HF and SONIC-HF cohorts, respectively. Kaplan-Meier survival curves demonstrated significantly higher mortality rates in patients with bendopnea than in those without bendopnea in the FRAGILE-HF (log-rank P = 0.006) and SONIC-HF cohorts (log-rank P = 0.014). Cox proportional hazard analysis identified bendopnea as an independent prognostic factor for all-cause mortality in both the FRAGILE-HF (hazard ratio [HR] 2.11, 95% confidence interval [CI] 1.18-3.78, P = 0.012) and SONIC-HF cohorts (HR 4.20, 95% CI 1.63-10.79, P = 0.003), even after adjusting for conventional risk factors. CONCLUSIONS Bendopnea was observed in a relatively small proportion of older patients hospitalized for heart failure before discharge. However, its presence was significantly associated with an increased risk of all-cause mortality.

Prognostic impact of MitraScore in elderly Asian patients with heart failure: sub-analysis of FRAGILE-HF. ESC Heart Fail 2024; 11:1039-1050. [PMID: 38243376 DOI: 10.1002/ehf2.14658] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2023] [Revised: 10/28/2023] [Accepted: 12/18/2023] [Indexed: 01/21/2024] Open
Abstract
AIMS MitraScore is a novel, simple, and manually calculatable risk score developed as a prognostic model for patients undergoing transcatheter edge-to-edge repair (TEER) for mitral regurgitation. As its components are considered prognostic in heart failure (HF), we aimed to investigate the usefulness of the MitraScore in HF patients. METHODS AND RESULTS We calculated MitraScore for 1100 elderly patients (>65 years old) hospitalized for HF in the prospective multicentre FRAGILE-HF study and compared its prognostic ability with other simple risk scores. The primary endpoint was all-cause deaths, and the secondary endpoints were the composite of all-cause deaths and HF rehospitalization and cardiovascular deaths. Overall, the mean age of 1100 patients was 80 ± 8 years, and 58% were men. The mean MitraScore was 3.2 ± 1.4, with a median of 3 (interquartile range: 2-4). A total of 326 (29.6%), 571 (51.9%), and 203 (18.5%) patients were classified into low-, moderate-, and high-risk groups based on the MitraScore, respectively. During a follow-up of 2 years, 226 all-cause deaths, 478 composite endpoints, and 183 cardiovascular deaths were observed. MitraScore successfully stratified patients for all endpoints in the Kaplan-Meier analysis (P < 0.001 for all). In multivariate analyses, MitraScore was significantly associated with all endpoints after covariate adjustments [adjusted hazard ratio (HR) (95% confidence interval): 1.22 (1.10-1.36), P < 0.001 for all-cause deaths; adjusted HR 1.17 (1.09-1.26), P < 0.001 for combined endpoints; and adjusted HR 1.24 (1.10-1.39), P < 0.001 for cardiovascular deaths]. The Hosmer-Lemeshow plot showed good calibration for all endpoints. The net reclassification improvement (NRI) analyses revealed that the MitraScore performed significantly better than other manually calculatable risk scores of HF: the GWTG-HF risk score, the BIOSTAT compact model, the AHEAD score, the AHEAD-U score, and the HANBAH score for all-cause and cardiovascular deaths, with respective continuous NRIs of 0.20, 0.22, 0.39, 0.39, and 0.29 for all-cause mortality (all P-values < 0.01) and 0.20, 0.22, 0.42, 0.40, and 0.29 for cardiovascular mortality (all P-values < 0.02). CONCLUSIONS MitraScore developed for patients undergoing TEER also showed strong discriminative power in HF patients. MitraScore was superior to other manually calculable simple risk scores and might be a good choice for risk assessment in clinical practice for patients receiving TEER and those with HF.

Association and Prognostic Value of Multidomain Frailty Defined by Cumulative Deficit and Phenotype Models in Patients With Heart Failure. Can J Cardiol 2024; 40:677-684. [PMID: 38007218 DOI: 10.1016/j.cjca.2023.11.020] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2023] [Revised: 11/18/2023] [Accepted: 11/20/2023] [Indexed: 11/27/2023] Open
Abstract
BACKGROUND Frailty is associated with a poor prognosis in older patients with heart failure (HF). However, multidomain frailty assessment tools have not been established in patients with HF, and the association between the frailty phenotype and the deficit-accumulation frailty index in these patients is unclear. We aimed to understand this relationship and evaluate the prognostic value of the deficit-accumulation frailty index in older patients with HF. METHODS We retrospectively analyzed FRAGILE-HF cohort, which consisted of prospectively registered hospitalized patients with HF aged ≥ 65 years. The frailty index was calculated using 34 health-related items. The physical, social, and cognitive domains of frailty were evaluated using a phenotypic approach. The primary endpoint was all-cause mortality. RESULTS Among 1027 patients with HF (median age, 81 years; male, 58.1%; median frailty index, 0.44), a higher frailty index was associated with a higher prevalence in all domains of cognitive, physical, and social frailty defined by the phenotype model. During the 2-year follow-up period, a higher frailty index was independently associated with all-cause death even after adjustment for Meta-Analysis Global Group in Chronic Heart Failure (MAGGIC) score plus log B-type natriuretic peptide (per 0.1 increase: hazard ratio, 1.21; 95% confidence interval, 1.07-1.37; P = 0.002). The addition of the frailty index to the baseline model yielded statistically significant incremental prognostic value (net reclassification improvement, 0.165; 95% confidence interval, 0.012-0.318; P = 0.034). CONCLUSIONS A higher frailty index was associated with a higher prevalence of all domains of frailty defined by the phenotype model and provided incremental prognostic information with pre-existing risk factors in older patients with HF.

Abstract
AIMS Although sarcopenia is common and associated with poor outcomes in patients with heart failure, its simple screening methods remain unclear. We aimed to investigate the predictive value of the Ishii score, which includes age, grip strength, and calf circumference, for sarcopenia and its prognostic predictability in patients with heart failure. METHODS This was a subanalysis of the FRAGILE-HF study. Receiver operating characteristic curves were used to evaluate the predictive value for sarcopenia. Patients were stratified into the high and low Ishii score groups based on the cutoff values of the Ishii score determined by the Youden index for sarcopenia, and the 1-year mortality rates were compared. RESULTS Of the 1262 study participants, 936 were evaluated with sarcopenia, and 184 (55 women, 129 men) were diagnosed with sarcopenia. The areas under the receiver operating characteristic curves for sarcopenia were 0.73 and 0.87 for women and men, respectively. The optimal cutoff values for predicting sarcopenia were 165 and 141 for women and men, respectively. Using these cutoff values, the sensitivity and specificity for sarcopenia were 70.9% and 68.5% for women and 88.4% and 69.7% for men, respectively. At 1 year, 151 (low Ishii score group, 98; high Ishii score group, 53) deaths were observed. Adjusted Cox proportional hazards analysis showed that the high Ishii score group was significantly associated with 1-year mortality. CONCLUSION Among older patients hospitalized for heart failure, the Ishii score is useful for predicting sarcopenia and 1-year mortality. Geriatr Gerontol Int 2024; 24: 147-153.

Prognostic impact of cachexia by multi-assessment in older adults with heart failure: FRAGILE-HF cohort study. J Cachexia Sarcopenia Muscle 2023; 14:2143-2151. [PMID: 37434419 PMCID: PMC10570094 DOI: 10.1002/jcsm.13291] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/11/2022] [Revised: 03/17/2023] [Accepted: 06/12/2023] [Indexed: 07/13/2023] Open
Abstract
BACKGROUND Cachexia substantially impacts the prognosis of patients with heart failure (HF); however, there is no standard method for cachexia diagnosis. This study aimed to investigate the association of Evans's criteria, consisting of multiple assessments, with the prognosis of HF in older adults. METHODS This study is a secondary analysis of the data from the FRAGILE-HF study, a prospective multicentre cohort study that enrolled consecutive hospitalized patients aged ≥65 years with HF. Patients were divided into two groups: the cachexia and non-cachexia groups. Cachexia was defined according to Evans's criteria by assessing weight loss, muscle weakness, fatigue, anorexia, a decreased fat-free mass index and an abnormal biochemical profile. The primary outcome was all-cause mortality, as assessed in the survival analysis. RESULTS Cachexia was present in 35.5% of the 1306 enrolled patients (median age [inter-quartile range], 81 [74-86] years; 57.0% male); 59.6%, 73.2%, 15.6%, 71.0%, 44.9% and 64.6% had weight loss, decreased muscle strength, a low fat-free mass index, abnormal biochemistry, anorexia and fatigue, respectively. All-cause mortality occurred in 270 patients (21.0%) over 2 years. The cachexia group (hazard ratio [HR], 1.494; 95% confidence interval [CI], 1.173-1.903; P = 0.001) had a higher mortality risk than the non-cachexia group after adjusting for the severity of HF. Cardiovascular and non-cardiovascular deaths occurred in 148 (11.3%) and 122 patients (9.3%), respectively. The adjusted HRs for cachexia in cardiovascular mortality and non-cardiovascular mortality were 1.456 (95% CI, 1.048-2.023; P = 0.025) and 1.561 (95% CI, 1.086-2.243; P = 0.017), respectively. Among the cachexia diagnostic criteria, decreased muscle strength (HR, 1.514; 95% CI, 1.095-2.093; P = 0.012) and low fat-free mass index (HR, 1.424; 95% CI, 1.052-1.926; P = 0.022) were significantly associated with high all-cause mortality, but there was no significant association between weight loss alone (HR, 1.147; 95% CI, 0.895-1.471; P = 0.277) and all-cause mortality. CONCLUSIONS Cachexia evaluated by multi-assessment was present in one third of older adults with HF and was associated with a worse prognosis. A multimodal assessment of cachexia may be helpful for risk stratification in older patients with HF.

Prevalence and prognostic impact of the coexistence of cachexia and sarcopenia in older patients with heart failure. Int J Cardiol 2023; 381:45-51. [PMID: 36934990 DOI: 10.1016/j.ijcard.2023.03.035] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/03/2023] [Revised: 03/12/2023] [Accepted: 03/16/2023] [Indexed: 03/21/2023]
Abstract
BACKGROUND No study with an adequate patients' number has examined the relationship/overlap between sarcopenia and cachexia. We examined the prevalence of the overlap and prognostic implications of sarcopenia and cachexia in older patients with heart failure using well-accepted definitions. METHODS This was a post-hoc sub-analysis of the FRAGILE-HF study, a prospective, multicenter, observational study conducted at 15 hospitals in Japan. In total, 905 hospitalized older patients were classified into four groups based on the presence or absence of cachexia and/or sarcopenia, which were defined according to the Evans and Asian Working Group for Sarcopenia criteria revised in 2019, respectively. The primary endpoint was 2-year all-cause mortality. RESULTS Cachexia and sarcopenia prevalence rates were 32.7% and 22.7%, respectively. Patients were classified into the non-cachexia/non-sarcopenia (55.7%), cachexia/non-sarcopenia (21.7%), non-cachexia/sarcopenia (11.6%), and cachexia/sarcopenia (11.0%) groups. During the 2-year follow-up period after discharge, 158 (17.5%) all-cause deaths (124 cardiovascular deaths [CVD] and 34 non-CVD) were observed. The cachexia/sarcopenia group had the lowest body fat mass and exhibited significantly higher mortality rates (log-rank P < 0.001). Cox proportional hazard analysis revealed that cachexia/sarcopenia was an independent prognostic factor after adjusting for known prognostic factors (versus non-cachexia/non-sarcopenia: hazard ratio, 2.78; 95% confidence interval, 1.80-4.29; P < 0.001). Neither cachexia/non-sarcopenia nor non-cachexia/sarcopenia were significantly associated with all-cause mortality compared with non-cachexia/non-sarcopenia. CONCLUSIONS Cachexia and sarcopenia are prevalent among older hospitalized patients with heart failure; nonetheless, the overlap is not as prominent as previously expected. The presence of cachexia and sarcopenia is a risk factor for all-cause mortality.

Histological evaluation of vascular changes after excimer laser angioplasty for neointimal formation after bare-metal stent implantation in rabbit iliac arteries. Cardiovasc Interv Ther 2023; 38:223-230. [PMID: 36609899 DOI: 10.1007/s12928-022-00905-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2022] [Accepted: 12/21/2022] [Indexed: 01/09/2023]
Abstract
BACKGROUND Excimer laser is used to treat coronary artery disease, especially in case of lesions with thrombus and in-stent restenosis (ISR). However, there are no in vivo preclinical studies that have evaluated the pathological reactions of the vessel wall after excimer laser ablation. METHODS Bare-metal stents were placed in the external iliac arteries of six healthy rabbits. Twenty-eight days later, excimer laser ablation was performed with low-power (45 (fluency)/25 (rate)) in one side, and high-power (60/40) in the opposite side, followed by optical coherence tomography (OCT) evaluation. Rabbits were sacrificed 15 min after the procedure, and histological assessment was performed. RESULTS Morphometry analysis of OCT showed similar stent and lumen size between low-power and high-power group. Histological evaluation suggested endothelial cell loss, fibrin deposition, and tissue loss. The low-power group showed significantly less pathological changes compared with the high-power group: angle of endothelial cell loss, 32.4° vs. 191.7° (interquartile range, 8.8°-131.7° vs. 125.7°-279.5°; p < 0.01); fibrin deposition, 1.1° vs. 59.6° (0.0°-70.4° vs. 31.4°-178.4°; p = 0.03); and tissue loss 0.0° vs. 18.2° (0.0°-8.7° vs. 0.0°-42.7°; p = 0.03). CONCLUSIONS The pathological changes in neointima were more prominent after high-power excimer laser ablation than after low-power excimer laser. To improve safety in clinical practice, understanding the pathological changes of tissues after excimer laser in lesions with ISR is essential.

Estimation of adverse events associated with P2Y12 receptor inhibitors stratified by academic research consortium for high bleeding risk criteria in acute coronary syndrome. Int J Cardiol 2023; 375:1-6.

Abstract
BACKGROUND The usefulness of the Academic Research Consortium for High Bleeding Risk (ARC-HBR) criteria in the selection of P2Y12 receptor inhibitors for acute coronary syndrome is unknown. This study investigated whether the selection of antiplatelet agents according to the ARC-HBR criteria could improve clinical outcomes. METHODS This multicenter retrospective study included 1261 patients with acute coronary syndrome who received dual antiplatelet therapy, namely clopidogrel (75 mg, n = 529) or prasugrel (3.75 mg, n = 732) in addition to aspirin. The primary endpoint was net adverse clinical events (NACE) after hospital admission, including ischemic (death, myocardial infarction, ischemic stroke) and bleeding events (Bleeding Academic Research Consortium 3 or 5). Secondary outcomes were ischemic and bleeding events. For each patient, the observation period was defined as the duration of dual antiplatelet therapy after admission. RESULTS During the observation period (average: 313 days), the rate of NACE was lower in the prasugrel group than the clopidogrel group (20.6% vs. 12.6%, respectively, P < 0.01). In patients who satisfied or did not satisfy the ARC-HBR criteria, prasugrel was associated with a 3.7% and 2.1% lower incidence of NACE, respectively, versus clopidogrel. Ischemic and bleeding events were less frequent in the prasugrel group than the clopidogrel group (11.5% vs. 7.9%, respectively, P = 0.03; 10.6% vs. 5.2%, respectively, P < 0.01). The estimated incidence models for NACE suggested that the difference between clopidogrel and prasugrel was greater in patients who satisfied the ARC-HBR criteria than in those who did not. CONCLUSIONS Prasugrel is preferable to clopidogrel regardless of the ARC-HBR.

Prognostic implications of six-minute walking distance in patients with heart failure with preserved ejection fraction. Int J Cardiol 2023; 379:76-81. [PMID: 36914073 DOI: 10.1016/j.ijcard.2023.03.025] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/24/2023] [Revised: 02/19/2023] [Accepted: 03/07/2023] [Indexed: 03/15/2023]
Abstract
BACKGROUND The incremental prognostic value of the six-minute walking test over conventional risk factors has not been evaluated in an adequate number of patients with heart failure with preserved ejection fraction (HFpEF). Therefore, we aimed to examine its prognostic significance using data from the FRAGILE-HF study. METHODS AND RESULTS A total of 513 older patients who were hospitalized for worsening heart failure were examined. Patients were classified according to the tertiles of six-minute walking distance (6MWD): T1 (<166 m), T2 (166-285 m), and T3 (≥285 m). During the 2-year follow-up period after discharge, 90 all-cause deaths occurred. Kaplan-Meier curves showed that the T1 group had significantly higher event rates than the other groups (log-rank p = 0.007). Cox proportional hazard analysis revealed that the T1 group was independently associated with lower survival, even after adjusting for conventional risk factors (T3: hazard ratio 1.79, 95% confidence interval 1.02-3.14, p = 0.042). The addition of the 6MWD to the conventional prognostic model showed a statistically significant incremental prognostic value (net reclassification improvement 0.27, 95% confidence interval 0.04-0.49; p = 0.019). CONCLUSIONS The 6MWD is associated with survival in patients with HFpEF and has an incremental prognostic value over conventional well-validated risk factors.

Abstract
Objective This study examined the ability of a combination of biomarkers, including N-terminal pro-B-type natriuretic peptide (N-BNP) and high-sensitivity C-reactive protein (hs-CRP), to better predict mortality than the Global Registry of Acute Coronary Events (GRACE) score in acute myocardial infarction (AMI) patients who received primary percutaneous coronary intervention (PPCI). Methods The in-hospital mortality in 754 all-comer patients with AMI who underwent successful PPCI over 8 years was examined. A receiver operating characteristic (ROC) analysis was performed to determine the in-hospital mortality in a single center. A logistic regression analysis was used to compare the predictive accuracy of the GRACE score and biomarkers. The incremental predictive value of those biomarkers beyond the GRACE score was also examined. Results The mean age was 66±13 years old, and 609 patients with ST-elevated AMI (80.8%) were included. The in-hospital mortality was 6.8%. The GRACE score (in-hospital survivor/non-survivor: 106±33/161±32; p<0.05,) and N-BNP (in-hospital survivor/non-survivor: 2,458±7,058/8,880±1,1331 pg/mL; p<0.05) were significantly lower in survivors than in non-survivors. The area under the ROC curve (AUC) of in-hospital mortality of the GRACE score was significantly higher than that of the dual-biomarker combination (0.868/0.720; p<0.05). The AUC of the combination of the GRACE score and dual-biomarkers was not significantly higher than that of the GRACE score alone (0.870/0.868; p=0.747). Conclusion The measurement of representative cardiovascular biomarkers did not provide any additional benefit for mortality prediction beyond the GRACE score in AMI patients who received PPCI.

Sustained Myocarditis following Messenger RNA Vaccination against Coronavirus Disease 2019: Relation to Neutralizing Antibody and Amelioration by Low-Dose Booster Vaccination. J Clin Med 2023; 12:jcm12041421. [PMID: 36835957 PMCID: PMC9961568 DOI: 10.3390/jcm12041421] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2023] [Revised: 02/02/2023] [Accepted: 02/07/2023] [Indexed: 02/16/2023] Open
Abstract
We recently reported that sub-acute myocarditis occurred following the initial two doses of messenger RNA-based vaccination against coronavirus disease 2019 (0.3 mL Comirnaty®) in elderly Japanese patients with cardiac dysfunction. The present retrospective study of 76 patients revealed that myocarditis following the initial doses persisted for 12 months, was associated with low levels of neutralizing antibodies, and was ameliorated by reducing the third vaccine dose. Low neutralizing antibody levels (<220 U/mL) after the initial doses were an independent predictor of persistent clinical events, defined as death or marked changes in brain natriuretic peptide levels. When the third dose was reduced (0.1 mL), changes in brain natriuretic peptide levels were significantly smaller (p = 0.02, n = 25), no deaths occurred due to heart failure, and neutralizing antibody levels increased 41-fold (p < 0.001) compared with the initial doses. Reduced booster doses could facilitate the worldwide distribution of messenger RNA vaccines.

Sarcopenic obesity is associated with impaired physical function and mortality in older patients with heart failure: insight from FRAGILE-HF. BMC Geriatr 2022; 22:556. [PMID: 35787667 PMCID: PMC9254413 DOI: 10.1186/s12877-022-03168-3] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/03/2021] [Accepted: 05/16/2022] [Indexed: 11/10/2022] Open
Abstract
Background The purpose of this study was to clarify the prevalence, association with frailty and exercise capacity, and prognostic implication of sarcopenic obesity in patients with heart failure. Methods The present study included 779 older adults hospitalized with heart failure (median age: 81 years; 57.4% men). Sarcopenia was diagnosed based on the guidelines by the Asian Working Group for Sarcopenia. Obesity was defined as the percentage of body fat mass (FM) obtained by bioelectrical impedance analysis. The FM cut-off points for obesity were 38% for women and 27% for men. The primary endpoint was 1-year all-cause death. We assessed the associations of sarcopenic obesity occurrence with the short physical performance battery (SPPB) score and 6-minute walk distance (6MWD). Results The rates of sarcopenia and obesity were 19.3 and 26.2%, respectively. The patients were classified into the following groups: non-sarcopenia/non-obesity (58.5%), non-sarcopenia/obesity (22.2%), sarcopenia/non-obesity (15.3%), and sarcopenia/obesity (4.0%). The sarcopenia/obesity group had a lower SPPB score and shorter 6MWD, which was independent of age and sex (coefficient, − 0.120; t-value, − 3.74; P < 0.001 and coefficient, − 77.42; t-value, − 3.61; P < 0.001; respectively). Ninety-six patients died during the 1-year follow-up period. In a Cox proportional hazard analysis, sarcopenia and obesity together were an independent prognostic factor even after adjusting for a coexisting prognostic factor (non-sarcopenia/non-obesity vs. sarcopenia/obesity: hazard ratio, 2.48; 95% confidence interval, 1.22–5.04; P = 0.012). Conclusion Sarcopenic obesity is a risk factor for all-cause death and low physical function in older adults with heart failure.

Effect of Cardiac Rehabilitation on Glomerular Filtration Rate Using Serum Cystatin C Concentration in Patients With Cardiovascular Disease and Renal Dysfunction. J Cardiopulm Rehabil Prev 2022; 42:E15-E22.

Abstract
PURPOSE Among patients with chronic kidney disease (CKD), little is known about whether the effect of cardiac rehabilitation (CR) on renal function differs across baseline estimated glomerular filtration rate using the serum concentration of cystatin C (eGFRcys). The aim of this study was to evaluate the effect of CR on renal function in patients with CKD. METHODS We performed a retrospective cohort study of patients with CKD (15 ≤ eGFRcys < 60 mL/min/1.73 m2) who participated in our CR program for cardiovascular disease. First, the patients were divided into three groups according to the baseline severity of the eGFRcys: G3a, G3b, and G4 groups. We compared the eGFRcys before and after the CR in each group. Second, to determine the association of baseline eGFRcys with the effect of CR, we fitted a linear regression model using the percent change in the eGFRcys (%ΔeGFRcys) as an outcome. RESULTS Of the 203 patients, 122 were in G3a, 60 were in G3b, and 21 were in G4 groups. The mean improvement of eGFRcys in each group was 1.3, 3.1, and 4.8 mL/min/1.73 m2, respectively. The %ΔeGFRcys was larger among patients with lower baseline eGFRcys (0.47% greater improvement of %ΔeGFRcys/one lower baseline eGFRcys; 95% CI, 0.23-0.72%). This association remained significant after adjustment for potential confounders (0.63% greater improvement of %ΔeGFRcys/one lower baseline eGFRcys; 95% CI, 0.35-0.91%). CONCLUSIONS The effect of CR on renal function was greater in patients with worse renal dysfunction measured by eGFRcys. A CR program could be useful for patients with severe renal dysfunction and it might have a beneficial effect on their renal function.

Prevalence and prognostic impact of cognitive frailty in elderly patients with heart failure: sub-analysis of FRAGILE-HF. ESC Heart Fail 2022; 9:1574-1583. [PMID: 35182038 PMCID: PMC9065815 DOI: 10.1002/ehf2.13844] [Citation(s) in RCA: 16] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2021] [Revised: 01/12/2022] [Accepted: 02/04/2022] [Indexed: 11/12/2022] Open
Abstract
Aims Although evidence suggests that cognitive decline and physical frailty in elderly patients with heart failure (HF) are associated with prognosis, the impact of concurrent physical frailty and cognitive impairment, that is, cognitive frailty, on prognosis has yet to be fully investigated. The current study sought to investigate the prevalence and prognostic impact of cognitive frailty in elderly patients with HF. Methods and results This study is a sub‐analysis of FRAGILE‐HF, a prospective multicentre observational study involving patients aged ≥65 years hospitalized for HF. The Fried criteria and Mini‐Cog were used to diagnose physical frailty and cognitive impairment, respectively. The association between cognitive frailty and the combined endpoint of mortality and HF rehospitalization within 1 year was then evaluated. Among the 1332 patients identified, 1215 who could be assessed using Mini‐Cog and the Fried criteria were included in this study. Among those included, 279 patients (23.0%) had cognitive frailty. During the follow‐up 1 year after discharge, 398 combined events were observed. Moreover, cognitive frailty was determined to be associated with a higher incidence of combined events (log‐rank: P = 0.0146). This association was retained even after adjusting for other prognostic factors (hazard ratio: 1.55, 95% confidence interval: 1.13–2.13). Furthermore, a sensitivity analysis using grip strength, short physical performance battery, and gait speed to determine physical frailty instead of the Fried criteria showed similar results. Conclusions This cohort study found that 23% of elderly patients with HF had cognitive frailty, which was associated with a 1.55‐fold greater risk for combined events within 1 year compared with patients without cognitive frailty.

Abstract
BACKGROUND AND AIMS Frailty and sarcopenia are common and confer poor prognosis in elderly patients with heart failure; however, gender differences in its prevalence or prognostic impact remain unclear. METHODS AND RESULTS We included 1332 patients aged ≥65 years, who were hospitalized for heart failure. Frailty and sarcopenia were defined using the Fried phenotype model and Asian Working Group for Sarcopenia criteria, respectively. Gender differences in frailty and sarcopenia, and interactions between sex and prognostic impact of frailty/sarcopenia on 1-year mortality were evaluated. Overall, 53.9% men and 61.0% women and 23.7% men and 14.0% women had frailty and sarcopenia, respectively. Although sarcopenia was more prevalent in men, no gender differences existed in frailty after adjusting for age. On Kaplan-Meier analysis, frailty and sarcopenia were significantly associated with 1-year mortality in both sexes. On Cox proportional hazard analysis, frailty was associated with 1-year mortality only in men, after adjusting for confounding factors (hazard ratio [HR], 1.94; 95% confidence interval [CI], 1.19-3.16; P = 0.008 for men; HR, 1.63; 95% CI, 0.84-3.13; P = 0.147 for women); sarcopenia was an independent prognostic factor in both sexes (HR, 1.93; 95% CI, 1.13-3.31; P = 0.017 for men; HR, 3.18; 95% CI, 1.59-5.64; P = 0.001 for women). There were no interactions between sex and prognostic impact of frailty/sarcopenia (P = 0.806 for frailty; P = 0.254 for sarcopenia). CONCLUSIONS Frailty and sarcopenia negatively affect older patients with heart failure from both sexes. CLINICAL TRIALS This study was registered at the University Hospital Information Network (UMIN-CTR, unique identifier: UMIN000023929) before the first patient was enrolled.

Inaccurate recognition of own comorbidities is associated with poor prognosis in elderly patients with heart failure. ESC Heart Fail 2022; 9:1351-1359. [PMID: 35088546 PMCID: PMC8934983 DOI: 10.1002/ehf2.13824] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2021] [Revised: 11/30/2021] [Accepted: 01/14/2022] [Indexed: 12/29/2022] Open
Abstract
Aims A patient's understanding of his or her own comorbidities is part of the recommended patient education for those with heart failure. The accuracy of patients' understanding of their comorbidities and its prognostic impact have not been reported. Methods and results Patients hospitalized for heart failure (n = 1234) aged ≥65 years (mean age: 80.1 ± 7.7 years; 531 females) completed a questionnaire regarding their diagnoses of diabetes, malignancy, stroke, hypertension, chronic obstructive pulmonary disease (COPD), and coronary artery disease (CAD). The patients were categorized into three groups based on the number of agreements between self‐reported comorbidities and provider‐reported comorbidities: low (1–2, n = 19); fair (3–4, n = 376); and high (5–6, n = 839) agreement groups. The primary outcome was a composite of all‐cause mortality or heart failure rehospitalization at 1 year. The low agreement group had more comorbidities and a higher prevalence of a history of heart failure. The agreement was good for diabetes (κ = 0.73), moderate for malignancy (κ = 0.56) and stroke (κ = 0.50), and poor‐to‐fair for hypertension (κ = 0.33), COPD (κ = 0.25), and CAD (κ = 0.30). The fair and low agreement groups had poorer outcomes than the good agreement group [fair agreement group: hazard ratio (HR): 1.25; 95% confidence interval (CI): 1.01–1.56; P = 0.041; low agreement group: HR: 2.74: 95% CI: 1.40–5.35; P = 0.003]. Conclusions The ability to recognize their own comorbidities among older patients with heart failure was low. Patients with less accurate recognition of their comorbidities may be at higher risk for a composite of all‐cause mortality or heart failure rehospitalization.

Distal radial approach treating a left main lesion during hemostasis of the forearm radial artery on the same side in a case of unstable angina. J Cardiol Cases 2022; 25:52-54. [PMID: 35024071 PMCID: PMC8721261 DOI: 10.1016/j.jccase.2021.06.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2021] [Revised: 05/25/2021] [Accepted: 06/09/2021] [Indexed: 12/05/2022] Open
Abstract
Conventional radial access (cRA) for percutaneous coronary intervention (PCI) has become the current standard due to low bleeding complications, although recently, distal radial access (dRA) has attracted attention as an alternative. Here, the usefulness of dRA is shown in a case in whom neither side could be used for cRA. The patient was a woman in her 70 s diagnosed with unstable angina pectoris at another hospital. Although ad hoc PCI was attempted via her right forearm radial artery, her hemodynamics deteriorated and the procedure was abandoned. After an intra-aortic balloon pumping device was inserted via the left femoral approach and hemostasis was established with a dedicated device, the patient was transferred to our hospital. Her right radial artery was being used for hemostasis and her left radial artery was poorly palpable. Because her right distal radial artery was palpable, access via that location was attempted after confirming sufficient blood vessel diameter and blood flow by ultrasound. A 6Fr sheath was inserted and PCI was safely accomplished. Hemostasis on dRA was completed without complications using a hemostasis device. Thus, dRA may be an option as an alternative access site in an emergency. <Learning objective: Radial access is recommended by the guidelines for coronary intervention in order to prevent access site complications. We report a case of unstable angina successfully treated for a left main lesion via the distal radial artery during hemostasis of the forearm radial artery on the same side. Distal radial access, little considered for catheterization, may be an alternative option when conventional radial access cannot be employed. It is important to share this conclusion with all physicians.>

Work status before admission relates to prognosis in older patients with heart failure partly through social frailty. J Cardiol 2021; 79:439-445. [PMID: 34819268 DOI: 10.1016/j.jjcc.2021.10.029] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/06/2021] [Revised: 10/09/2021] [Accepted: 10/13/2021] [Indexed: 10/19/2022]
Abstract
BACKGROUND No reports explicitly examined the relationship between work defined as a certain type of social participation or role and the protective effect on the prognosis of patients with heart failure (HF) by preventing frailty. Therefore, this study examined whether social participation through work before admission relates to future adverse events in HF patients aged ≥65 years, and whether each frailty domain mediates the association between work and prognosis as a second analysis of a multi-centered prospective study (FRAGILE-HF study). METHODS We retrospectively reviewed 1,332 older patients with HF whose work status before admission to the hospital were investigated. We assessed the physical, cognitive, and social domains of frailty and performed causal mediation analysis to examine the mediating relationship of each frail domain between work status before admission and 1-year combined events (HF-related readmission and all-cause death). RESULTS The subjects' median age was 81 years, and 56.9% (758/1,332) were male. Among the three domains of frailty, work before admission reduced only social frailty after adjusting for confounding factors (odds ratio: 0.505, 95% confidence interval: 0.364-0.701). Patients with work before admission had a significantly better prognosis (hazard ratio: 0.720, 95% confidence interval: 0.523-0.989). Only social frailty partly mediated the relationship between work status and combined events (p <0.05). CONCLUSIONS Work status before admission is associated with 1-year combined events, in part through social frailty.

Abstract
OBJECTIVES The transradial approach (TRA) is recommended in coronary catheterization due to the lower rate of bleeding complications compared with the transfemoral approach. However, a disadvantage of TRA is difficulty in puncturing under palpation of the radial pulse alone without arterial visibility. To overcome this limitation, a vessel visualization device using near-infrared rays, Art View (Forte Grow Medical Company), was used in the puncture of the radial artery (RA). METHODS Patients who underwent coronary angiography via the right RA with Art View were retrospectively surveyed. According to the quality of RA visibility, the performance of the Art View was rated as follows: 5 = excellent; 4 = good; 3 = fair; 2 = not good; and 1 = poor. The primary endpoint was the procedural success of TRA using the Art View device. The secondary endpoints were procedural time (from injection of local anesthesia to successful crossing of the guidewire attached to the sheath), number of RA punctures, and change of puncture method or approach site. RESULTS The Art View device was used in 38 patients (mean age, 71 ± 11 years). Puncturing of the visualized RA was successful in 30 patients (79.0%). Among successful cases, the mean procedural time was 142 ± 87 seconds. The success rates of each visualization evaluation were 100%, 100%, 84.6%, 33.3%, and 0% from grades 5 to 1, respectively (P<.01). The mean procedural times were 92 ± 18 seconds, 102 ± 58 seconds, 180 ± 75 seconds, 306 ± 80 seconds, and not available from grades 5 to 1, respectively (P<.01). CONCLUSION The Art View RA visualization device is useful for RA puncture.

Abstract
Recently, the efficacy was demonstrated of the Diamondback 360® Coronary Orbital Atherectomy System (OAS) (Cardiovascular Systems, Inc., St. Paul, MN, USA) for treating calcified coronary lesions in percutaneous coronary intervention (PCI). The safety and feasibility of OAS application through a 5-Fr guiding catheter (GC) which is less invasive and reduces access site complications were validated. This sequential, retrospective, observational study was conducted in a single center from September 2018 to May 2020. The primary endpoint was a successful PCI with the OAS. Secondary endpoints were major adverse complications related to PCI with the OAS, including coronary dissection, perforation, side branch loss, need for an unexpected cardiac assist device, access site complications, and major adverse cardiac and cerebrovascular events. 33 PCIs in 30 patients (mean age 72 ± 11 years; male, 83.3%) were surveyed. All PCIs were successfully completed with OAS application through a 5-Fr GC. Coronary perforation after the OAS procedure occurred in one case (3.0%). Severe coronary dissection occurred in three cases (9.1%), and procedural myocardial infarction in two cases (6.1%). Regarding PCIs performed with the 5-Fr GC, the OAS is a safe and feasible strategy for calcified plaque modification.

Abstract
Background Frailty is conceptualized as an accumulation of deficits in multiple areas and is strongly associated with the prognosis of heart failure (HF). However, the social domain of frailty is less well investigated. We prospectively evaluated the clinical characteristics and prognostic impact of social frailty (SF) in elderly patients with HF. Methods and Results FRAGILE‐HF (prevalence and prognostic value of physical and social frailty in geriatric patients hospitalized for heart failure) is a multicenter, prospective cohort study focusing on patients hospitalized for HF and aged ≥65 years. We defined SF by Makizako’s 5 items, which have been validated as associated with future disability. The primary end point was a composite of all‐cause death and rehospitalization because of HF. The impact of SF on all‐cause mortality alone was also evaluated. Among 1240 enrolled patients, 825 (66.5%) had SF. During the 1‐year observation period after discharge, the rates of the combined end point and all‐cause mortality were significantly higher in patients with SF than in those without SF (Log‐rank test: both P < 0.05). SF remained as significantly associated with both the combined end point (hazard ratio, 1.30; 95% CI, 1.02–1.66; P = 0.038) and all‐cause mortality (hazard ratio, 1.53; 95% CI, 1.01–2.30; P = 0.044), even after adjusting for key clinical risk factors. Furthermore, SF showed significant incremental prognostic value over known risk factors for both the combined end point (net‐reclassification improvement: 0.189, 95% CI, 0.063–0.316, P = 0.003) and all‐cause mortality (net‐reclassification improvement: 0.234, 95% CI, 0.073–0.395, P = 0.004). Conclusions Among hospitalized geriatric patients with HF, two thirds have SF. Evaluating SF provides additive prognostic information in elderly patients with HF.

Aspartate aminotransferase to alanine aminotransferase ratio is associated with frailty and mortality in older patients with heart failure. Sci Rep 2021; 11:11957.

Abstract
Frailty is a common comorbidity associated with adverse events in patients with heart failure, and early recognition is key to improving its management. We hypothesized that the AST to ALT ratio (AAR) could be a marker of frailty in patients with heart failure. Data from the FRAGILE-HF study were analyzed. A total of 1327 patients aged ≥ 65 years hospitalized with heart failure were categorized into three groups based on their AAR at discharge: low AAR (AAR < 1.16, n = 434); middle AAR (1.16 ≤ AAR < 1.70, n = 487); high AAR (AAR ≥ 1.70, n = 406). The primary endpoint was one-year mortality. The association between AAR and physical function was also assessed. High AAR was associated with lower short physical performance battery and shorter 6-min walk distance, and these associations were independent of age and sex. Logistic regression analysis revealed that high AAR was an independent marker of physical frailty after adjustment for age, sex and body mass index. During follow-up, all-cause death occurred in 161 patients. After adjusting for confounding factors, high AAR was associated with all-cause death (low AAR vs. high AAR, hazard ratio: 1.57, 95% confidence interval, 1.02–2.42; P = 0.040). In conclusion, AAR is a marker of frailty and prognostic for all-cause mortality in older patients with heart failure.

Abstract
BACKGROUND The BP-SES has an abluminally applied biodegradable polymer that is fully resorbed after 3-4 months but may have longer-lasting effects. The aim of this study was to determine the long-term vascular response to the novel Ultimaster™ sirolimus-eluting stent (BP-SES). METHODS BP-SESs, everolimus-eluting stents (DP-EESs), and bare metal stents were implanted in 22 coronary arteries of 15 mini-swine. All animals underwent optical frequent domain imaging (OFDI) to assess neointimal volume and quality at either 1 (n = 7) or 3 (n = 8) months and at 9 (n = 15) months and were euthanized at 9 months. Stents were subsequently histologically investigated to analyze the vascular response and maturity of neointimal tissue according to cell density. RESULTS OFDI revealed greater regression in neointimal volume from 3 to 9 months with BP-SESs than with DP-EESs (-0.6 ± 0.5 mm2 vs. 0.00 ± 0.4 mm2, p = 0.07). Although there was no significant difference between BP-SESs and DP-EESs in the inflammation score (BMS, BP-SES, and DP-EES: 0.1 ± 0.1, 0.3 ± 0.4, and 0.4 ± 0.4, respectively; p < 0.0001) in histological analysis, BP-SESs showed slightly greater maturity than DP-EESs (1.8 ± 0.3, 1.7 ± 0.3, and 1.6 ± 0.3, p = 0.09). CONCLUSIONS While both BP-SESs and DP-EESs showed minimal inflammatory responses at 9 months, BP-SESs showed a trend for greater neointimal maturity and regression, which may be related to earlier completion of the vascular response.

Validity and Utility of the Questionnaire-based FRAIL Scale in Older Patients with Heart Failure: Findings from the FRAGILE-HF. J Am Med Dir Assoc 2021; 22:1621-1626.e2. [PMID: 33785309 DOI: 10.1016/j.jamda.2021.02.025] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2020] [Revised: 02/02/2021] [Accepted: 02/09/2021] [Indexed: 01/22/2023]
Abstract
OBJECTIVES We investigated whether the FRAIL scale questionnaire is consistent with the Fried criteria, predicts all-cause mortality, and reflects physical dysfunction in patients with heart failure (HF). DESIGN Secondary analysis of FRAGILE-HF, a cohort study that enrolled participants from 2016 to 2018 and followed-up for 1-year of discharge. SETTING AND PARTICIPANTS A prospective multicenter cohort study in which 15 hospitals in Japan (8 university hospitals and 7 nonuniversity teaching hospitals) participated. We prospectively enrolled 1332 consecutive hospitalized patients ≥65 years old with HF and analyzed 1028 patients after excluding 304 patients with missing data on the FRAIL scale. METHODS The FRAIL scale, the Fried model, and physical function were measured before discharge. The endpoint was all-cause mortality. RESULTS According to the FRAIL scale, 459 (44.6%) and 491 (47.8%) were classified as frail and prefrail, respectively. The Kappa coefficient between the FRAIL scale and the Fried criteria were 0.39 [95% confidence interval (CI) 0.34-0.44; P < .001]. The area under the receiver-operating characteristic curves for frailty diagnosed by the Fried criteria of the FRAIL scale was 0.74 (95% CI 0.71-0.76; P < .001). A total of 118 deaths occurred during 1 year of follow-up. After adjusting for the MAGGIC risk score and log-BNP, The FRAIL scale predicted all-cause mortality (hazard ratio 1.17; 95% CI 1.01-1.36; P = .035). The FRAIL scale was also associated with various physical dysfunctions that correlated with poor prognosis. CONCLUSIONS AND IMPLICATIONS The FRAIL scale had moderate consistency with the Fried criteria, predicted all-cause mortality, and reflected clinically important physical dysfunctions.

Prevalence and prognostic value of the coexistence of anaemia and frailty in older patients with heart failure. ESC Heart Fail 2020; 8:625-633. [PMID: 33295134 PMCID: PMC7835564 DOI: 10.1002/ehf2.13140] [Citation(s) in RCA: 16] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2020] [Revised: 11/01/2020] [Accepted: 11/11/2020] [Indexed: 12/17/2022] Open
Abstract
Aims There have been no investigations of the prevalence and clinical implications of coexistence of anaemia and frailty in older patients hospitalized with heart failure (HF) despite their association with adverse health outcomes. The present study was performed to determine the prevalence and prognostic value of the coexistence of anaemia and frailty in hospitalized older patients with HF. Methods and results We performed post hoc analysis of consecutive hospitalized HF patients ≥65 years old enrolled in the FRAGILE‐HF, which was the prospective, multicentre, observational study. Anaemia was defined as haemoglobin < 13 g/dL in men and <12 g/dL in women, and frailty was evaluated according to the Fried phenotype model. The study endpoint was all‐cause mortality. Of the total of 1332 patients, 1217 (median age, 81 years; 57.4% male) were included in the present study. The rates of anaemia and frailty in the study population were 65.7% and 57.0%, respectively. The patients were classified into the non‐anaemia/non‐frail group (16.6%), anaemia/non‐frail group (26.4%), non‐anaemia/frail group (17.7%), and anaemia/frail group (39.3%). A total of 144 patients died during 1 year of follow‐up. In multivariate analyses, only the anaemia/frail group showed a significant association with elevated mortality rate (adjusted hazard ratio, 1.94; 95% confidence interval, 1.02–3.70; P = 0.043), compared with the non‐anaemia/non‐frail group after adjusting for other covariates. Conclusions Coexistence of anaemia and frailty are prevalent in hospitalized older patients with HF, and it has a negative impact on mortality.

Impact of sarcopenia on prognosis in patients with heart failure with reduced and preserved ejection fraction. Eur J Prev Cardiol 2020; 28:1022-1029.

Abstract
AIMS Sarcopenia, one of the extracardiac factors for reduced functional capacity and poor outcome in heart failure (HF), may act differently between HF with preserved ejection fraction (HFpEF) and HF with reduced ejection fraction (HFrEF). We sought to investigate the impact of sarcopenia on mortality in HFpEF and HFrEF. METHODS AND RESULTS We performed a post hoc analysis of a multicentre prospective cohort study, including 942 consecutive older (age ≥65 years) hospitalized patients: 475 with HFpEF (ejection fraction ≥45%, age 81 ± 7 years, 48.8% men) and 467 with HFrEF (ejection fraction <45%, age 78 ± 8 years, 68.1% men). Sarcopenia was diagnosed according to the international criteria incorporating muscle strength (handgrip strength), physical performance (gait speed), and skeletal muscle mass (appendicular skeletal mass). The HFpEF group consisted of fewer patients with low appendicular skeletal muscle mass index measured using bioelectrical impedance analysis [<7.0 kg/m2 (men) and <5.7 (women); 22.1% vs. 31.0%, P = 0.003], and more patients with low handgrip strength [<26 kg (men) and <18 (women); 67.8% vs. 55.5%, P < 0.001], and slow gait speed [<0.8 m/s (both sexes); 54.5% vs. 41.1%, P < 0.001] than the HFrEF group, resulting in a similar sarcopenia prevalence in the two groups (18.1% vs. 21.6%, P = 0.191). Sarcopenia was an independent predictor of 1-year mortality in both HFpEF and HFrEF [hazard ratio (95% confidence interval) 2.42 (1.36-4.32), P = 0.003 in HFpEF and 2.02 (1.08-3.75), P = 0.027 in HFrEF; P for interaction = 0.666] after adjustment for other predictors. CONCLUSIONS In older patients with HF, sarcopenia contributes to mortality similarly in HFpEF and HFrEF.

Abstract
Abstract
Background/Introduction
Sarcopenia plays a major role in the pathophysiology of frailty and is associated with worse outcome in the elderly population including patients with heart failure. A recent update of the most common definition of sarcopenia in Asia, Asian Working Group for Sarcopenia (AWGS2019), included significant changes in the diagnostic algorithm with newly dividing sarcopenia into severe and “non-severe” sarcopenia.
Purpose
The objective of this study was to evaluate the differences between AWGS2014 and AWGS2019 in patients with heart failure.
Methods
In the multicenter prospective FRAGILE-HF registry, which included elderly (≥65 years old) patients who were hospitalized with heart failure, we studied 865 patients (80±8 years old, 42% female). All-cause death in 1-year follow-up was tracked.
Results
Based on the original version of AWGS (AWGS2014), 183 patients (21%) were diagnosed with sarcopenia, which was associated with higher age, lower physical performance, less muscle mass, and greater heart failure risk (all p<0.001) as well as higher rate of all-cause death (HR 1.90, p=0.004 after adjustment by multivariable regression). Those patients with sarcopenia by AWGS2014 were reclassified mainly to severe sarcopenia (155, 84.7%) by AWGS2019, and 25 (13.7%) and 2 (1.1%) were classified into sarcopenia and non-sarcopenia. Meanwhile, 24 (3.5%) and 4 (0.6%) of patients without sarcopenia by AWGS2014 were reclassified into sarcopenia and severe sarcopenia, respectively. Although severe sarcopenia by AWGS2019 was associated with higher age, lower physical performance, less muscle mass, and greater heart failure risk (all p<0.001), patients with “non-severe” sarcopenia was rather younger (p<0.001) and had better physical performance (p=0.021) despite less muscle mass (p<0.001) than those without sarcopenia. Multivariate Cox analysis demonstrated severe sarcopenia by AWGS2019 was an independent prognostic factor (HR 1.77, p=0.014), but “non-severe” sarcopenia was not (HR 1.52, p=0.37). The prognosis of patients who were reclassified from non-sarcopenia to sarcopenia or severe sarcopenia were comparable to those remained non-sarcopenia. When added to other risk factors, the prognostic predictability of AWGS2019 was significantly lower than AWGS2014 (net reclassification improvement −0.26, p=0.025).
Conclusions
About a half of “non-severe” sarcopenia in AWGS2019 were patients without sarcopenia in AWGS2014. The prognosis of such patients who were newly diagnosed as sarcopenia was good, resulting in low overall prognostic predictability of AWGS2019. A further consideration for diagnostic algorithms of sarcopenia may be warranted in patients with heart failure.

Social frailty provides additive prognostic impact on one-year outcome in aged patients with congestive heart failure. Eur Heart J 2020.

Abstract
Abstract
Background
Frailty is associated with multisystem declines in physiologic reserve and increased vulnerability to stressors, resulting in increased risks of adverse clinical outcomes in patients with heart failure (HF). Although frailty is conceptualized as an accumulation of deficits in multiple areas, most of the studies have focused mainly on physical frailty, and the social domains is one of the least investigated area.
Objectives
We prospectively evaluated the incidence and prognostic implication of social frailty (SF) in older patients with HF.
Methods
The FRAGILE-HF is a multicenter, prospective cohort study including patients hospitalized for HF and aged ≥65 years old. We defined SF by Makizako's 5 items, which are 5 questions proposed and validated to be associated with future disability. The primary endpoint of this study was a composite of death from any cause and rehospitalization due to HF. The impact of SF on all-cause mortality alone was also evaluated.
Results
Among 1,240 hospitalized HF patients, 5 simple questions revealed that 825 (66.5%) were in SF. During 1-year observation period after the discharge, the combined endpoint was observed in 399 (32.2%) patients, and 145 (11.7%) patients died. Kaplan-Meier analysis showed that SF patients had significantly higher rates of both the combined endpoint and all-cause mortality than those without SF (Log-rank test: p<0.05 for both, Figures). Moreover, SF remained independently associated with higher event rate of the combined endpoint (hazard ratio: 1.30; 95% confidence interval: 1.02 to 1.66; p=0.038) and all-cause mortality (hazard ratio: 1.53; 95% confidence interval: 1.01 to 2.30; p=0.044), even after adjusting for other covariates. Significant incremental prognostic value was shown when information on social frailty was added to known risk factors for combined endpoint (NRI: 0.189, 95% confidence interval: 0.063–0.316, p=0.003) and all-cause mortality (NRI: 0.234, 95% confidence interval: 0.073–0.395, p=0.004).
Conclusions
Among older hospitalized patients with heart failure, two-thirds of the population was with SF. Evaluating SF provides additive prognostic information in elderly patients with heart failure.

Prevalence and prognostic impact of the coexistence of multiple frailty domains in elderly patients with heart failure: the FRAGILE-HF cohort study. Eur J Heart Fail 2020; 22:2112-2119. [PMID: 32500539 DOI: 10.1002/ejhf.1926] [Citation(s) in RCA: 100] [Impact Index Per Article: 25.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/13/2020] [Revised: 05/27/2020] [Accepted: 05/27/2020] [Indexed: 12/11/2022] Open
Abstract
AIMS To describe the prevalence, overlap, and prognostic implications of physical and social frailties and cognitive dysfunction in hospitalized elderly patients with heart failure. METHODS AND RESULTS The FRAGILE-HF study was a prospective multicentre cohort study enrolling consecutive hospitalized patients with heart failure aged ≥65 years. The study objectives were to examine the prevalence, overlap, and prognostic implications of the coexistence of multiple frailty domains. Physical frailty, social frailty, and cognitive dysfunction were evaluated by the Fried phenotype model, Makizako's 5 items, and Mini-Cog, respectively. The primary study outcome was the combined endpoint of heart failure rehospitalization and all-cause death within 1 year. Among 1180 enrolled hospitalized patients (median age, 81 years; 57.4% male), physical frailty, social frailty, and cognitive dysfunction were identified in 56.1%, 66.4%, and 37.1% of the patients, respectively. The number of identified frailty domains was 0, 1, 2, and 3 in 13.5%, 31.4%, 36.9%, and 18.2% of the patients, respectively. During follow-up, the combined endpoint occurred in 383 patients. Adjusted hazard ratios for 1, 2, and 3 domains, with 0 domains as the reference, were 1.38 [95% confidence interval (CI) 0.89-2.13; P = 0.15], 1.60 (95% CI 1.04-2.46; P = 0.034), and 2.04 (95% CI 1.28-3.24; P = 0.003), respectively. Incorporating the number of frailty domains into the pre-existing risk model yielded a 22.0% (95% CI 0.087-0.352; P = 0.001) net reclassification improvement for the primary outcome. CONCLUSIONS The coexistence of multiple frailty domains is prevalent in hospitalized elderly patients with heart failure. Holistic assessment of multi-domain frailty provides additive value to known prognostic factors.

Abstract
Current drug-eluting stents have abluminal polymer coating; however, thrombus formation in these compared with that in uniformly coated stents remains controversial. We evaluated thrombus formation and early endothelialization after using abluminal biodegradable polymer-coated sirolimus- (BP-SES), and everolimus-eluting stents (BP-EES) versus a durable polymer-coated everolimus-eluting stent (DP-EES) in an in vivo setting. BP-SES, BP-EES, and DP-EES (n = 6 each) were implanted in coronary arteries of 12 mini-pigs that were then sacrificed after 7 and 10 days. Stents were stained with hematoxylin and eosin, and a combined Verhoeff and Masson trichrome stain. Areas of fibrin deposition were digitally detected and measured with off-line morphometric software. Stents were investigated for re-endothelialization by transmission electron microscopy. At 7 days, histological analysis revealed the lowest area of fibrin deposition in BP-SES (BP-SES vs. BP-EES vs. DP-EES; 0.10 ± 0.06 mm2 vs. 0.15 ± 0.07 mm2 vs. 0.19 ± 0.06 mm2, p = 0.0004). At 10 days, the area of fibrin deposition was significantly greater in DP-EES (0.13 ± 0.04 mm2 vs. 0.14 ± 0.05 mm2 vs. 0.19 ± 0.08 mm2, p = 0.007). Endothelial cells in BP-SES demonstrated a significantly greater number of tight junctions than those in DP-EES according to by transmission electron microscopy for both days (p<0.05). Various parameters, including an inflammatory reaction and neointimal formation, were comparable among the groups at 7 and 10 days. An abluminal biodegradable polymer-coated SES showed the least fibrin deposition and greatest endothelial cell recovery at an early stage following implantation in the coronary arteries of mini-pigs.

Relation Between Autonomic Nervous Activity after Pulmonary Vein Isolation and Recurrence in Paroxysmal Atrial Fibrillation Patients. THE TOKAI JOURNAL OF EXPERIMENTAL AND CLINICAL MEDICINE 2018; 43:153-160.

Abstract
OBJECTIVE Pulmonary vein isolation (PVI) has been widely used for the treatments of paroxysmal atrial fibrillation (PAF); however, AF recurrence remains a significant challenge. We evaluated relation between autonomic nervous activity and AF recurrence using heart rate variability (HRV) and deceleration and acceleration capacity (DC/AC) analyses. METHODS High-resolution Holter electrocardiogram was performed in 56 PAF patients pre- and 3 and 6 months post-PVI by cryoballoon. HRV and DC/AC analysis data were compared between the non-recurrence and recurrence groups. RESULTS AF recurrence occurred in 10 cases. Total heart beats and maximum heart rate significantly decreased and minimum heart rate increased only in the non-recurrence group post-PVI. In HRV analysis, root mean square successive difference (RMSSD), low-frequency components (LF), high frequency components (HF) and LF/HF significantly decreased only in the non-recurrence group at both 3 and 6 months post-PVI; in contrast, significant decreases in RMSSD, LF and HF were observed in the recurrence group only at 6 months. In DC/AC analysis, DC significantly decreased in both groups post-PVI; in contrast, AC increased only in the non-recurrence group, resulting in significantly greater [AC]/DC ratio in the recurrence group at 3 months post-PVI. CONCLUSIONS To prevent AF recurrence after PVI, it is important not only to reduce vagosympathetic overall activity but also to minimize imbalance between vagosympathetic reflex responses.

Abstract
Although extracorporeal life support (ECLS) is utilized for acute hemodynamic collapse, clinical outcomes for such patients are uncertain. The present study examined 30-day clinical outcomes in patients treated with ECLS for acute hemodynamic collapse, and determined the factors associated with 30-day mortality in patients who required ECLS for cardiopulmonary arrest (CPA). A total of 200 patients, in whom emergency ECLS was utilized for acute hemodynamic collapse from 2006 to 2015, were analyzed retrospectively. The impact of CPA on all-cause 30-day death in the overall population was examined by multivariable logistic regression analysis; comparisons were made between 30-day survivors (n = 78) and non-survivors (n = 122). In addition, clinical factors associated with 30-day survival for patients in whom ECLS was utilized for CPA (n = 139) were examined. All-cause 30-day mortality in the overall study population was 61 % (122/200). CPA was the most common cause of ECLS requirement (70 %), and the factor associated strongest with death at 30-days (OR 3.31, 95 % CI 1.75-6.36, P < 0.01). Witnessed CPA with bystander cardiopulmonary resuscitation (CPR) (OR 4.33, 95 % CI 1.08-29.1, P = 0.04) and a less than 40 min interval between CPA and ECLS (OR 3.49, 95 % CI 1.39-9.02, P < 0.01) were suggested as factors associated with 30-day survival in CPA patients. CPA as a trigger of ECLS was a strong contributor to 30-day death in patients in whom emergency ECLS was utilized. However, witnessed CPA with bystander CPR and a less than 40 min interval from CPA to start of ECLS were suggested as factors associated with survival in these CPA patients.

Abstract
Background Incomplete endothelialization is the primary substrate of late stent thrombosis; however, recent reports have revealed that abnormal vascular responses are also responsible for the occurrence of late stent failure. The aim of the current study was to assess vascular response following deployment of biodegradable polymer‐based Synergy (Boston Scientific) and Nobori (Terumo) drug‐eluting stents and the durable polymer‐based Resolute Integrity stent (Medtronic) in an atherosclerotic rabbit iliac artery model. Methods and Results A total of 24 rabbits were fed an atherogenic diet, and then a balloon injury was used to induce atheroma formation. Synergy, Nobori, and Resolute Integrity stents were randomly implanted in iliac arteries. Animals were euthanized at 28 days for scanning electron microscopic evaluation and at 90 days for histological analysis. The percentage of uncovered strut area at 28 days was lowest with Synergy, followed by Resolute Integrity, and was significantly higher with Nobori stents (Synergy 1.1±2.2%, Resolute Integrity 2.0±3.9%, Nobori 4.6±3.0%; P<0.001). At 90 days, inflammation score was lowest for Synergy (0.27±0.45), followed by Nobori (0.62±0.59), and was highest for Resolute Integrity (0.89±0.46, P<0.001). Foamy macrophage infiltration within neointima (ie, neoatherosclerosis) was significantly less with Synergy (0.62±0.82) compared with Nobori (0.85±0.74) and Resolute Integrity (1.39±1.32; P=0.034). Conclusions The biodegradable polymer‐coated thin‐strut Synergy drug‐eluting stent showed the fastest stent strut neointimal coverage and the lowest incidence of neoatherosclerosis in the current animal model.

Abstract
A 57-year-old man with a history of hepatitis B virus infection was referred to our hospital for living-donor liver transplantation (LDLT). Five years earlier, right lobectomy had been performed for solitary hepatocellular carcinoma (HCC) with bile duct tumor thrombus in segments 5 and 6 in the liver. Two years later, transarterial chemoembolization and radiofrequency ablation were performed for recurrent HCC. Two years after those local therapies, another recurrent HCC was treated with transhepatic arterial infusion chemotherapy with cisplatin and conventional radiation therapy (RT) with 60 Gy in 20 fractions, because the tumor was contiguous to the trunk of the portal vein. After the completion of RT, symptoms due to liver failure and severe infection caused by multiple liver abscesses developed despite the administration of antibiotics and percutaneous transhepatic cholangiodrainage. Therefore, LDLT was performed with the use of a right lobe graft donated by his wife. Vascular anastomosis was successfully performed with the use of normal procedures. The patient recovered uneventfully, and has since been doing well for 34 months, with no evidence of vascular complications. However, the degree of injury to the anastomotic vessels caused by definitive RT before LDLT remains unclear, whereas the safety and efficacy of some forms of RT as a bridge to deceased-donor LT have been reported. Salvage LDLT is effective for patients with liver failure after multidisciplinary treatment including radiation, while carefully taking radiation-induced vessel injury as a potential late complication into consideration, especially in LDLT cases.

Abstract
BACKGROUND Portal vein tumour thrombosis is a negative prognostic factor for hepatocellular carcinoma (HCC). AIM To assess the efficacy of cisplatin in lipiodol emulsion combined with 5-fluorouracil (5-FU) for patients with HCC and portal vein tumour thrombosis. METHODS The study subjects were 51 patients with the above-specified criteria who received injection of cisplatin suspension in lipiodol emulsion followed by intra-arterial infusion of 5-FU. The primary objective was to determine tumour response to the treatment, while the secondary objectives were safety and tolerability. Independent factors for survival were also assessed. RESULTS Ten patients had complete response and 34 patients had partial response (response rate, 86.3%). The median survival for all 51 patients was 33 months, while that for 10 complete response patients and 21 patients who showed disappearance of HCC following additional therapies was 39 months. The single factor that significantly influenced survival was therapeutic effect. Treatment was well tolerated and severe toxicity was infrequent, with only grade 3 toxicity (thrombocytopenia) in one patient. CONCLUSIONS The present study demonstrated the efficacy of hepatic arterial infusion chemotherapy using cisplatin-lipiodol emulsion and 5-FU without serious adverse effects in patients with unresectable HCC and portal vein tumour thrombosis.

Abstract
To determine the risk factors for development of transitional cell carcinoma (TCC) of the bladder (BTCC) following surgery for TCC of the upper urinary tract (UUT-TCC) in patients without history of BTCC, 85 patients surgically treated for UUT-TCC (34 female, 51 male; median age 66, range 42-85 years) were reviewed retrospectively. The Cox proportional hazards model was used to assess the association of relevant clinicopathologic factors with BTCC-free survival in patients without a history of BTCC and TCC-specific survival in all. Median follow-up duration was 35 (range 1-193) months. Six patients (7%) had previous histories of BTCC, and 6 others (7%) had concurrent BTCC at the time of surgery for UUT-TCC. Of 70 patients who had no history of BTCC and underwent follow-up cystoscopy, 24 (34%) developed BTCC during follow-up after surgery. Univariate analysis identified female sex, postoperative systemic chemotherapy, and incomplete distal ureterectomy as significant risk factors for new development of BTCC. After multivariate analysis adjusted for age and pathological (p) T stage in the TNM classification, all three factors remained significant, with respective hazard ratios of 5.56 (95% confidence interval (CI), 1.99-15.6; p = 0.001), 3.19 (95% CI, 1.34-7.62; p = 0.009) and 2.99 (95% CI, 1.08-8.26; p = 0.03). Only pT stage was a significant independent risk factor for TCC-specific death. Female sex and postoperative systemic chemotherapy, as well as incomplete distal ureterectomy, are possible riks factors for development of BTCC following surgery for UUT-TCC.

Abstract
UNLABELLED Sympathetic cardiopulmonary nerves arise from the cervical sympathetic trunks and travel alongside the great arteries to innervate the ventricles. Because of the proximity of the nerve and artery, cardiac sympathetic denervation may occur in patients who have just undergone surgery for the repair of an ascending aortic aneurysm. METHODS To evaluate the cardiac sympathetic activity in aortic aneurysm, we performed cardiac 123I-metaiodobenzylguanidine (MIBG) imaging on 12 patients (mean age +/- SD, 47 +/- 17 y) before and after the surgical repair of an aneurysm. Seven patients scheduled for coronary artery bypass grafting also underwent 123I-MIBG imaging as controls for open-chest surgery. Planar images were obtained at 15 min (early) and 4 h (delayed) after injection of 111 MBq 123I-MIBG, and the cardiac 123I-MIBG uptake was graded quantitatively and visually. The quantitative evaluation was based on the heart-to-mediastinum ratio (H/M), and visual evaluation was performed by assigning a score of 0-3 (0 = absent, 1 = severely reduced, 2 = reduced, and 3 = normal). Heart rate variability using 24-h Holter electrocardiography was analyzed before and after the operation to generate a time-domain index of heart rate variability as an index of autonomic balance. RESULTS In patients with aortic aneurysms, both early and delayed H/Ms were significantly decreased after the operation (early H/M: 1.84 +/- 0.16 before vs. 1.40 +/- 0.16 after, P = 0.001; delayed H/M: 1.79 +/- 0.38 before vs. 1.27 +/- 0.18 after, P = 0.004). Visual analysis of 123I-MIBG accumulation in early images showed absence of 123I-MIBG accumulation in 3 of 12 patients, a score of 1 in 7 patients, and a score of 2 in 2 patients. In contrast, no significant difference between H/M before surgery and H/M after surgery was seen in patients who underwent coronary artery bypass grafting. The time-domain index of heart rate variability was significantly lower after the operation than before (135 +/- 40 after vs. 96 +/- 27 before, P < 0.05). CONCLUSION Cardiac sympathetic nerves are totally or partially denervated after the surgical repair of ascending aortic aneurysm.

Abstract
The wearing behaviors of a hybrid composite resin for crown and bridge (ES) were examined using a two-body impacting-sliding wear test with a porcelain (PO), Au-Ag-Pd alloy (PD), direct restorative composite resin (CR) and tooth enamel (TO). Although PO was the hardest of all, it showed the largest wear together with ES in the combination of ES-PO, which was probably initiated from the superficial destruction by their impact. The wear in ES-PD was the second largest. It was noted in this combination that the surface of ES was partially contaminated by scraped thin layers of PD to a degree distinguished by the naked eye. The mutual wears of the components were relatively low in the combination of ES with CR, TO or ES itself. It is suggested from these findings that the hybrid composite resin may be useful as an alternative to porcelain for posterior crown and bridge unless it opposes porcelain or alloys.

Abstract
Pulmonary metastasis is frequently seen in patients with advanced hepatocellular carcinoma. However, information is limited concerning life-threatening complications and effective treatment of pulmonary metastasis because of the poor prognosis of patients with advanced hepatocellular carcinoma. Recent remarkable progress in detection and treatment of hepatocellular carcinoma has improved prognosis, making management of pulmonary metastasis an important clinical issue. We describe a 68-year-old man with pulmonary metastasis of hepatocellular carcinoma and sudden onset of hemoptysis from bronchial invasion. Transcatheter embolization was performed successfully via the bronchial artery with disappearance of bloody sputum. Peribronchial pulmonary metastasis of hepatocellular carcinoma can cause life-threatening hemoptysis. Transcatheter arterial embolization may be one of therapeutics for hemoptysis from invasive pulmonary metastasis of hepatocellular carcinoma.

Abstract
To elucidate the risk factors for developing hepatocellular carcinoma (HCC) during the follow-up of patients with liver cirrhosis (LC), outpatients with LC were examined periodically by means of serum biochemical assessments, ultrasonography, and computed tomography. Risk factors for HCC were statistically analyzed. We also examined an efficacy of Lens culinaris agglutinin A-reactive profiles of alpha-fetoprotein (AFP-L3%) and des-gamma-carboxy prothrombin (DCP) value using a highly sensitive DCP determination kit (ED036) for the early recognition of HCC. The AFP-L3% and the ED036 value were retrospectively determined with stored serum samples. HCC was diagnosed in 21 of the 78 patients with LC during the follow-up period (mean follow-up period: 42 months). The estimated cumulative incidence of HCC was 25% with 3 years and 48% with 5 years. The most significant risk factor for the development of HCC in LC patients was found to be the mean serum AFP concentration from the year before the HCC detection (p=0.02). At the time of the recognition of HCC, the positive rates of the tumor markers were: serum AFP concentration 14%, serum DCP value 5%, AFP-L3% was 33%, and that of ED036 43%. The positive rate in collaborative use of AFP-L3% and ED036 was 67%. The simultaneous determination of the AFP-L3% and the ED036 value was shown to be effective for the early detection of HCC.

Abstract
Polyarteritis nodosa is a necrotizing angitis that predominantly affects small and medium-sized arteries. The prognosis of untreated polyarteritis nodosa is very poor. Since symptoms are diverse and no serologic test is specific for polyarteritis nodosa, the diagnosis is difficult and often delayed. We describe a patient with polyarteritis nodosa who had gastrointestinal involvement with multiple aneurysms of the inferior mesenteric artery; only abdominal angiography provided a conclusive diagnosis. Alleviation of symptoms and regression of aneurysms were observed after combination therapy of an immunosuppressive agent, cyclophosphamide, and prednisolone. We emphasize the importance of early diagnosis by angiography and aggressive therapy in patients in whom physical signs indicating definite polyarteritis nodosa are not present.

Abstract
A significant increase has been reported in reticuloendothelial neoplasms in patients with inflammatory bowel diseases. We present two rare cases of multiple myeloma in patients with inflammatory bowel diseases. One was in a 58-year-old woman with ulcerative colitis, and the other was in a 59-year old woman with Crohn's disease. In both patients, multiple myeloma occurred during long-term observation of inflammatory bowel disease and during the inactive stage of intestinal inflammation. The multiple myeloma appeared to have resulted from monoclonal gammopathy of undertermined significance in both patients, and was diagnosed by characteristic serum and bone marrow findings. Our findings suggested that multiple myeloma should be particularly considered in women of middle or advanced age with ulcerative colitis or Crohn's colitis and serum monoclonal gammopathy.

Abstract
Thirty-eight patients with genuine stress incontinence underwent the Gittes procedures of the bladder neck suspension under ultrasonical monitoring. We performed the following two procedures. Original Gittes procedure: the puncture of the needle made twice through the different holes of the rectus fascia for each side and the bilateral helical suture was tied down separately above the rectus fascia. Modified Gittes procedure: the needle was passed through the rectus fascia once for each side and the both end of the helical suture was drawn up to suprapubic area, then the bilateral threads were tied over the rectus fascia. Original Gittes procedure was performed for twenty-nine patients and modified Gittes procedure for nine patients. Tightness of the suspension was decided by monitoring the posterior urethrovesical angle with use of the transrectal ultrasonography during the operation. A long term follow up survey was made up by means of a questionnaire by the phone or the mail. A total of thirty-six patients responded the questionnaire for a 94.7% response rate. The mean follow up was 33.1 months. 83.3% of the patients were cured and 5.6% were significantly improved. None of the patients claimed dysuria. There was no difference between the continent rates of the two procedures. We conclude that the Gittes bladder neck suspension with use of ultrasonography is effective for correction of female stress urinary incontinence.

Abstract
This study was designed to evaluate posterior urethral sensation and sacral reflex evoked by posterior urethral stimulation to predict fate of pelvic nerve dysfunction. Enrolled were 24 male patients sequentially receiving the following examinations 1-3 months (postoperative) and more then 6 months (follow-up) after surgery for rectal cancer: sensory thresholds of the penile skin (SS) and the posterior urethra (SU), sacral reflex evoked by penile stimulation (BCR) and posterior urethral stimulation (UUR), and urodynamic study. Controls included 25 patients with normal voiding function before pelvic surgery. SS, SU and latencies of BCR and UUR averaged 1.9+/-0.6 mA, 5.6+/-1.8 mA, 33.3+/-4.2 ms and 65.0+/-9.3 ms in controls, respectively, and unchanged postoperatively in 13 patients with normal voiding function. Of 11 patients with voiding dysfunction whose SS and latency of BCR remained unchanged, SU increased in 7, voiding function remained unrecovered in 6 patients during the follow-up period and recovered in the remaining 5. None of four patients with nonevocable UUR recovered voiding function. Thus, unchanged SU and disappearance of UUR were useful to predict recovery and nonrecovery of postoperative voiding dysfunction, respectively.

Abstract
PURPOSE The durability of pubovaginal sling procedure for type 2 stress urinary incontinence was evaluated by a questionnaire survey. MATERIALS AND METHODS From 1989 to 1996, 48 patients with type 2 stress urinary incontinence were treated with a polytetrafluoroethylene patch sling. Tightness of the sling was adjusted by setting the posterior urethrovesical angle at about 90 degrees under ultrasound monitoring. Study inclusion criteria were no urine leakage for at least 24 months confirmed by questionnaire and no recurrent urinary incontinence during followup. RESULTS We received answers from 39 patients (81.3%), of whom 1 was excluded from study due to less than 24-month followup (18 months) without urine leakage. Of the 38 patients 32 (84.2%) reported no leakage of urine, 4 (10.5%) were subjectively improved, 2 (5.3%) were the same and none was worse, for an overall cure or improved rate of 94.7%. Followup of the 32 patients maintaining urinary continence averaged 65.9 +/- 29.4 months. Of the patients 6 (15.8%) had slight pelvic pain, 4 (10.5%) always and 10 (26.3%) sometimes had to strain to void, and 14 (36.8%) complained pollakisuria. Urge incontinence coexisted in 5 of 6 patients reporting improved or the same status. Of all patients 31 (81.6%) were satisfied with the decision to undergo the operation. CONCLUSIONS Durability and safety of our procedure for stress urinary incontinence were confirmed by the survey questionnaire. Most of the patients complained of no or little difficulty voiding.
