Geriatric Nutritional Risk Index predicts bleeding event in patients with heart failure.

AIMS: We aimed to elucidate the association between malnutrition and the occurrence of bleeding events in patients with heart failure. METHODS AND RESULTS: We evaluated the nutritional status of patients with heart failure [n = 2044, median (inter-quartile range) age 69.0 (59.0-78.0) years, 1209 (59.1%) males] using the Geriatric Nutritional Risk Index (GNRI). The primary endpoint was a composite of bleeding events such as haemorrhagic stroke or gastrointestinal bleeding. According to the survival classification and regression tree analysis, the accurate cut-off point of GNRI for predicting the primary endpoint was 106.2. We divided the patients into two groups based on GNRI levels: high GNRI group (GNRI ≥ 106.2, n = 606, 29.6%) and low GNRI group (GNRI < 106.2, n = 1438, 70.4%). We compared the patients' characteristics and prognosis between the two groups. The low GNRI group was older [72.0 (63.0-79.0) vs. 63.0 (53.0-73.0) years, P < 0.001] and had a lower prevalence of male sex (56.9% vs. 64.5%, P = 0.001). There were no differences in the use of antiplatelet agents and anticoagulants between the two groups. Levels of B-type natriuretic peptide were higher [321.1 (123.3-667.4) vs. 111.6 (42.6-235.4) pg/mL, P < 0.001] and levels of haemoglobin were lower [12.4 (10.8-13.7) vs. 14.2 (12.9-15.4) g/dL, P < 0.001] in the low GNRI group. The Kaplan-Meier analysis demonstrated that bleeding event rates were higher in the low GNRI group (log-rank P < 0.001). The multivariable Cox proportional hazard analysis revealed that low GNRI (hazard ratio 1.952, 95% confidence interval 1.002-3.805, P = 0.049) was associated with bleeding events. CONCLUSIONS: Heart failure patients with poor nutritional status, determined by GNRI under 106.2, experienced high bleeding event rates. Comprehensive management is required to avoid bleeding event in those populations.

Hepatic Venous Stasis Index Reflects Hepatic Congestion and Predicts Adverse Outcomes in Patients With Heart Failure.

Background It has been reported that the hepatic vein waveforms determined by abdominal ultrasonography can assess hepatic congestion in patients with heart failure (HF). However, the parameter that quantifies hepatic vein waveforms has not been established. We suggest the hepatic venous stasis index (HVSI) as the novel indicator to evaluate hepatic congestion quantitatively. To examine the clinical significance of HVSI in patients with HF, we aimed to clarify the associations of HVSI with the parameters of cardiac function and right heart catheterization, as well as that with prognosis, in patients with HF. Methods and Results We performed abdominal ultrasonography, echocardiography, and right heart catheterization in patients with HF (n=513). The patients were divided into 3 groups based on HVSI as follows: HVSI 0 (HVSI=0, n=253), low HVSI (HVSI 0.01-0.20, n=132), and high HVSI (HVSI>0.20, n=128). We examined the associations of HVSI with parameters of cardiac function and right heart catheterization and followed up for cardiac events defined as cardiac death or worsening HF. There was a significant increase in level of B-type natriuretic peptide, inferior vena cava diameter, and mean right atrial pressure with increasing HVSI. During the follow-up period, cardiac events occurred in 87 patients. In the Kaplan-Meier analysis, cardiac event rate increased across increasing HVSI (log-rank, P=0.002). Conclusions HVSI assessed by abdominal ultrasonography reflects hepatic congestion and right-sided HF and is associated with adverse prognosis in patients with HF.

Impact of bleeding event for new cancer diagnosis in patients with antiplatelet therapy after percutaneous coronary intervention.

BACKGROUND: Bleeding is a frequent event in coronary artery disease (CAD) patients treated with antiplatelet therapy after percutaneous coronary intervention (PCI). The impact of bleeding in CAD patients with antiplatelet therapy for cancer diagnosis remains unclear. METHODS AND RESULTS: Consecutive 1565 CAD patients treated with antiplatelet therapy after PCI, without anticoagulation therapy, were enrolled. We aimed to investigate the relationships between bleeding events and the incidence of new cancer diagnosis. Among 1565 patients, 178 (11.3 %) experienced any bleeding events defined as Bleeding Academic Research Consortium (BARC) type 1, 2, 3, or 5 bleeding and 75 (4.7 %) experienced minor bleeding events defined as BARC 1 or 2 bleeding, and 116 (7.4 %) were diagnosed with new cancer during a mean follow-up period of 1528 days. Among 178 patients with any bleeding and 75 patients with minor bleeding events, 20 (11.2 %) and 13 (17.3 %) were subsequently diagnosed with new cancer, respectively. The proportion of new cancer diagnosis was higher in patients with any bleeding and minor bleeding events than in those without bleeding events (3.3 versus 1.6 per 100 person-years, p < 0.001 and 6.2 versus 1.6 per 100 person-years, p < 0.001, respectively). Multivariate Cox proportional hazard analysis revealed that any bleeding and minor bleeding events were associated with higher rate of new cancer diagnosis [hazard ratio (HR) 2.27, p = 0.003 and HR 3.93, p < 0.001, respectively]. Additionally, any gastrointestinal bleeding and minor gastrointestinal bleeding events were associated with higher rate of new gastrointestinal cancer diagnosis (HR 8.67, p < 0.001 and HR 12.74, p < 0.001, respectively). CONCLUSIONS: In CAD patients with antiplatelet therapy after PCI, any bleeding and minor bleeding events were associated with subsequent new cancer diagnosis. Even minor bleeding events may be the first manifestation of underlying cancer during antiplatelet therapy after PCI.

Prognostic significance of spleen shear wave elastography and dispersion in patients with heart failure: the crucial role of cardio-splenic axis.

INTRODUCTION: The interaction between the heart and spleen plays a crucial role among cardiac and multiple organ networks, particularly in heart failure (HF). Ultrasound shear wave imaging is a non-invasive technology capable of quantifying tissue quality, but its significance in the spleen in patients with HF is poorly understood. METHODS AND RESULTS: This prospective observational study enrolled hospitalized 232 patients with HF undergoing abdominal ultrasonography. We used shear wave elastography (SWE) to assess spleen tissue elasticity and shear wave dispersion (SWD) to assess spleen tissue viscosity. Clinical, echocardiography, right heart catheterization, and outcome data were collected. Spleen SWE was negatively correlated with right ventricular fractional area change (R = - 0.180, P = 0.039), but not with right-sided pressure or congestion indices. When patients were divided into three groups based on tertile values of splenic parameters, Kaplan-Meier analysis demonstrated that patients with the highest spleen SWE and SWD had lower event-free survival rates from cardiac deaths and decompensated HF over a median 494-days follow-up period (P < 0.0001 and P < 0.0001, respectively). In a multivariable Cox proportional hazard model, both spleen SWE and SWD were independently associated with increased risks of adverse cardiac events (hazard ratio, 4.974 and 1.384; P = 0.003 and P < 0.0001). Mechanistically, we evaluated mRNA expressions of CD36, a monocyte/macrophage-associated molecule, in peripheral leukocytes, and found that enhanced spleen stiffness was associated with the upregulation of CD36 expressions. CONCLUSION: Share wave imaging of the spleen is useful for stratifying the prognosis of HF patients and may suggest a role of the cardio-splenic axis in HF pathogenies.

Persistent Hypochloremia Is Associated with Adverse Prognosis in Patients Repeatedly Hospitalized for Heart Failure.

BACKGROUND: Hypochloremia reflects neuro-hormonal activation in patients with heart failure (HF). However, the prognostic impact of persistent hypochloremia in those patients remains unclear. METHODS: We collected the data of patients who were hospitalized for HF at least twice between 2010 and 2021 (n = 348). Dialysis patients (n = 26) were excluded. The patients were divided into four groups based on the absence/presence of hypochloremia (<98 mmol/L) at discharge from their first and second hospitalizations: Group A (patients without hypochloremia at their first and second hospitalizations, n = 243); Group B (those with hypochloremia at their first hospitalization and without hypochloremia at their second hospitalization, n = 29); Group C (those without hypochloremia at their first hospitalization and with hypochloremia at their second hospitalization, n = 34); and Group D (those with hypochloremia at their first and second hospitalizations, n = 16). RESULTS: a Kaplan-Meier analysis revealed that all-cause mortality and cardiac mortality were the highest in Group D compared to the other groups. A multivariable Cox proportional hazard analysis revealed that persistent hypochloremia was independently associated with both all-cause death (hazard ratio 3.490, p < 0.001) and cardiac death (hazard ratio 3.919, p < 0.001). CONCLUSIONS: In patients with HF, prolonged hypochloremia over two hospitalizations is associated with an adverse prognosis.

A rare case of fibromuscular dysplasia with multifocal coronary artery involvement evaluated by intravascular ultrasound.

Fibromuscular dysplasia (FMD) is non-atherosclerotic, non-inflammatory vascular disease that results in arterial stenosis. The lesions in FMD are commonly found in the renal and extracranial carotid and vertebral arteries, but the prevalence of FMD with lesions in the coronary artery is unclear. Although the vascular morphology of coronary artery lesion in FMD is mostly dissection, the following case of FMD showed the stenotic and aneurysmal lesions in coronary arteries, which was treated by percutaneous coronary angioplasty. Several vascular imaging modalities including computed tomographic angiography and catheter angiography are used for diagnosing FMD, however, the intravascular ultrasound (IVUS) imaging of the coronary artery in FMD has not been well studied. Here we describe a rare case of FMD involving multifocal coronary artery lesions with coronary aneurysm which was evaluated by IVUS imaging. Learning objective: The vascular morphologies of coronary artery lesion in fibromuscular dysplasia (FMD) mostly appear as coronary dissection, however, multifocal stenotic and aneurysmal lesions can occur in coronary arteries in FMD as the following case shows. The intravascular ultrasound findings of the stenotic coronary lesions in FMD, that were circumferential thickening of intima with various echo patterns and echolucent circumferential thickened media, may help in the diagnosis of FMD involving coronary arteries.

Prognostic Effects of Changes in Right Ventricular Fractional Area Change in Patients With Heart Failure.

BACKGROUND: It is still unclear whether changes in right ventricular function are associated with prognosis in heart failure (HF) patients. This study aimed to examine the prognostic effect of changes in right ventricular fractional area change (RVFAC).Methods and Results: This study enrolled 480 hospitalized patients with decompensated HF, and measured RVFAC with echocardiography at discharge (first examination) and post-discharge in the outpatient setting (second examination). RVFAC was divided into 3 categories: >35% in 314 patients, 25-35% in 108 patients, and <25% in 58 patients. Next, based on changes in RVFAC from the first to the second examination, the patients were further classed into 4 groups: (1) Preserved/Unchanged (preserved and unchanged RVFAC, n=235); (2) Reduced/Improved (improved RVFAC in at least 1 category, n=106); (3) Reduced/Unchanged (reduced and unchanged RVFAC, n=47); and (4) Preserved or Reduced/Worsened (deteriorated RVAFC in at least 1 category, n=92). Multivariate logistic regression analysis revealed that chronic kidney disease and anemia were the predictors of the preserved or reduced/worsened RVFAC. In the Kaplan-Meier analysis, changes in RVFAC were associated with the cardiac event rate and all-cause mortality. In the multivariable Cox proportional hazard analysis, the preserved or reduced/worsened RVFAC was an independent predictor of cardiac events and all-cause mortality. CONCLUSIONS: Changes in RVFAC were associated with post-discharge prognosis in hospitalized heart failure patients.

Increases in Hepatokine Selenoprotein P Levels Are Associated With Hepatic Hypoperfusion and Predict Adverse Prognosis in Patients With Heart Failure.

Background Although multiorgan networks are involved in the pathophysiology of heart failure (HF), interactions of the heart and the liver have not been fully understood. Hepatokines, which are synthesized and secreted from the liver, have regulatory functions in peripheral tissues. Here, we aimed to clarify the clinical impact of the hepatokine selenoprotein P in patients with HF. Methods and Results This is a prospective observational study that enrolled 296 participants consisting of 253 hospitalized patients with HF and 43 control subjects. First, we investigated selenoprotein P levels and found that its levels were significantly higher in patients with HF than in the controls. Next, patients with HF were categorized into 4 groups according to the presence of liver congestion using shear wave elastography and liver hypoperfusion by peak systolic velocity of the celiac artery, which were both assessed by abdominal ultrasonography. Selenoprotein P levels were significantly elevated in patients with HF with liver hypoperfusion compared with those without but were not different between the patients with and without liver congestion. Selenoprotein P levels were negatively correlated with peak systolic velocity of the celiac artery, whereas no correlations were observed between selenoprotein P levels and shear wave elastography of the liver. Kaplan-Meier analysis demonstrated that patients with HF with higher selenoprotein P levels were significantly associated with increased adverse cardiac outcomes including cardiac deaths and worsening HF. Conclusions Liver-derived selenoprotein P correlates with hepatic hypoperfusion and may be a novel target involved in cardiohepatic interactions as well as a useful biomarker for predicting prognosis in patients with HF.

Decreases in hepatokine Fetuin-A levels are associated with hepatic hypoperfusion and predict cardiac outcomes in patients with heart failure.

BACKGROUND: Interactions of the heart and the liver remain to be fully understood in the pathophysiology of heart failure (HF). Hepatokines are proteins synthesized and secreted from the liver and regulate systemic metabolisms of peripheral tissues. This study sought to clarify the clinical relevance of hepatokine Fetuin-A in patients with HF. METHODS AND RESULTS: We enrolled 217 participants including 187 hospitalized patients with HF and 30 control subjects who were sought with a comparable age- and sex profile and who had never had HF or structural cardiac abnormalities. First, we examined the levels of Fetuin-A and found that its levels were significantly lower in patients with HF than in the controls. Next, HF patients were categorized into four groups based on hepatic hemodynamics assessed by abdominal ultrasonography which determines liver hypoperfusion by peak systolic velocity (PSV) of the celiac artery and liver stiffness by shear wave elastography (SWE). Fetuin-A levels were significantly decreased in HF patients with liver hypoperfusion compared to those without, but were not different between HF patients with and without elevated liver stiffness. Correlation analysis revealed that circulating Fetuin-A was positively correlated with PSV of the celiac artery but not with SWE of the liver. Kaplan-Meier analysis demonstrated that HF patients with lower Fetuin-A levels were significantly associated with increased adverse outcomes including cardiac deaths and decompensated HF. CONCLUSIONS: Liver-derived hepatokine Fetuin-A may be a novel target involved in the cardio-hepatic interactions, as well as a useful biomarker for predicting the prognosis in patients with HF.

Renal Venous Stasis Index Reflects Renal Congestion and Predicts Adverse Outcomes in Patients With Heart Failure.

Background: It has been recently reported that the renal venous stasis index (RVSI) assessed by renal Doppler ultrasonography provides information to stratify pulmonary hypertension that can lead to right-sided heart failure (HF). However, the clinical significance of RVSI in HF patients has not been sufficiently examined. We aimed to examine the associations of RVSI with parameters of cardiac function and right heart catheterization (RHC), as well as with prognosis, in patients with HF. Methods: We performed renal Doppler ultrasonography, echocardiography and RHC in hospitalized patients with HF (n = 388). RVSI was calculated as follows: RVSI = (cardiac cycle time-venous flow time)/cardiac cycle time. The patients were classified to three groups based on RVSI: control group (RVSI = 0, n = 260, 67%), low RVSI group (0 < RVSI ≤ 0.21, n = 63, 16%) and high RVSI group (RVSI > 0.21, n = 65, 17%). We examined associations of RVSI with parameters of cardiac function and RHC, and followed up for cardiac events defined as cardiac death or worsening HF. Results: There were significant correlations of RVSI with mean right atrial pressure (mRAP; R = 0.253, P < 0.001), right atrial area (R = 0.327, P < 0.001) and inferior vena cava diameter (R = 0.327, P < 0.001), but not with cardiac index (R = -0.019, P = 0.769). During the follow-up period (median 412 days), cardiac events occurred in 60 patients. In the Kaplan-Meier analysis, the cumulative cardiac event rate increased with increasing RVSI (log-rank, P = 0.001). In the multivariate Cox proportional hazard analysis, the cardiac event rate was independently associated with RVSI (high RVSI group vs. control group: hazard ratio, 1.908; 95% confidence interval, 1.046-3.479, P = 0.035). Conclusion: RVSI assessed by renal Doppler ultrasonography reflects right-sided overload and is associated with adverse prognosis in HF patients.

B-type natriuretic peptide is associated with the occurrence of bleeding events in heart failure patients with a history of coronary artery disease.

BACKGROUND: Bleeding risk in heart failure (HF) patients with coronary artery disease (CAD) has not yet been fully investigated. METHODS: We analyzed the data of 677 patients with a previous history of CAD who were hospitalized for HF. The patients were divided into three groups based on the tertiles of B-type natriuretic peptide (BNP) levels: Low, Middle, and High BNP groups (n = 225, 226, and 226, respectively). The primary endpoint was post-discharge bleeding events, which was defined as hemorrhagic stroke and gastrointestinal bleeding. RESULTS: The High BNP group was the oldest (Low, Middle, High, 67.0, 74.0, and 75.0 years, respectively; p < 0.001), showed the lowest left ventricular ejection fraction (56.0%, 50.7%, and 40.3%, respectively; p < 0.001), and contained more patients at high bleeding risk (HBR) defined by the simplified version of the Academic Research Consortium for High Bleeding Risk (ARC-HBR) definition (65.3%, 85.4%, and 93.8%, respectively, p < 0.001). Kaplan-Meier analysis demonstrated that post-discharge bleeding events occurred most frequently in the High BNP group (log-rank p = 0.008). In the Cox proportional hazard analysis, compared to the Low BNP group as a reference, the High BNP group was independently associated with bleeding events after adjustment for age, sex, simplified ARC-HBR definition, and left ventricular ejection fraction (hazard ratio 3.208, 95% confidence interval 1.078-9.544, p = 0.036). CONCLUSIONS: High BNP is associated with bleeding events in HF patients with a history of CAD.

Simplified Academic Research Consortium for High Bleeding Risk (ARC-HBR) Definition Predicts Bleeding Events in Patients With Heart Failure.

BACKGROUND: It has recently been reported that the simplified Academic Research Consortium for High Bleeding Risk (ARC-HBR) definition, which excludes 6 rare criteria, is comparable to the original ARC-HBR definition in predicting major bleeding in patients with coronary artery disease (CAD) who undergo percutaneous coronary intervention. In this study, we investigated whether the simplified ARC-HBR definition could be applied to patients with heart failure (HF) to identify those at high bleeding risk (HBR).Methods and Results:In all, 2,437 patients hospitalized for HF were enrolled in this study. Patients were divided into 2 groups based on the simplified ARC-HBR definition: those at HBR (n=2,026; 83.1%) and those not (non-HBR group; n=411; 16.9%). The HBR group was older (72.0 vs. 61.0 years; P<0.001) and had a lower prevalence of CAD (31.1% vs. 36.5%; P=0.034) than the non-HBR group. Kaplan-Meier analysis showed that post-discharge bleeding events defined as hemorrhagic stroke or gastrointestinal bleeding were more frequent in the HBR than non-HBR group (log-rank P<0.001). The simplified ARC-HBR definition accurately predicted bleeding events (Fine-Gray model; hazard ratio 2.777, 95% confidence interval 1.464-5.270, P=0.001). CONCLUSIONS: The simplified ARC-HBR definition predicts a high risk of bleeding events in patients with HF.

Liver Congestion Assessed by Hepatic Vein Waveforms in Patients With Heart Failure.

BACKGROUND: It has been reported that the pattern of hepatic vein (HV) waveforms determined by abdominal ultrasonography is useful for the diagnosis of hepatic fibrosis in patients with chronic liver disease. We aim to clarify the clinical implications of HV waveform patterns in patients with heart failure (HF). METHODS: We measured HV waveforms in 350 HF patients, who were then classified into 3 categories based on their waveforms: those with a continuous pattern (C group); those whose V wave ran under the baseline (U group), and those with a reversed V wave (R group). We performed right-heart catheterization, and examined the rate of postdischarge cardiac events, such as cardiac death and rehospitalization due to worsening HF. RESULTS: The number of patients in each of the 3 HV waveform groups was as follows: C group, n = 158; U group, n = 152, and R group, n = 40. The levels of B-type natriuretic peptide (R vs C and U; 245.8 vs 111.7 and 216.6 pg/mL; P < 0.01) and mean right atrial pressure (10.5 vs 6.7 and 7.2 mm Hg; P < 0.01) were highest in the R group compared with the other groups. The Kaplan-Meier analysis found that cardiac event-free rates were lowest in the R group among all groups (log-rank P < 0.001). In the multivariable Cox proportional hazard analysis, the R group was found to be an independent predictor of cardiac events (hazard ratio, 4.90; 95% confidence interval, 2.23-10.74; P < 0.01). CONCLUSION: Among HF patients, those with reversed V waves had higher right atrial pressure and were at higher risk of adverse prognosis.

INTRODUCTION: Nous avons appris que le tracé ondulatoire de la veine hépatique (VH) à l'échographie abdominale est utile au diagnostic de la fibrose hépatique chez les patients atteints d'une maladie chronique du foie. Nous avons pour objectif de clarifier les implications cliniques des tracés ondulatoires de la VH chez les patients atteints d'insuffisance cardiaque (IC). MÉTHODES: Nous avons mesuré les ondulations de la VH de 350 patients atteints d'IC et les avons ensuite classifiés en trois catégories selon leurs ondulations : ceux qui avaient un tracé continu (groupe C); ceux dont l'onde V se présentait selon les valeurs de référence (groupe U); ceux qui avaient une onde V inversée (groupe R). Nous avons réalisé un cathétérisme cardiaque droit et examiné le taux d'événements cardiaques après la sortie de l'hôpital tels que la mort d'origine cardiaque et la réhospitalisation en raison de l'aggravation de l'IC. RÉSULTATS: Le nombre de patients dans chacun des trois groupes d'ondulations de la VH était réparti comme suit : groupe C, n = 158; groupe U, n = 152 et groupe R, n = 40. Les concentrations en peptides natriurétiques de type B (R vs C et U; 245,8 vs 111,7 et 216,6 pg/ml; P < 0,01) et la pression moyenne de l'oreillette droite (10,5 vs 6,7 et 7,2 mmHg; P < 0.01) étaient plus élevées dans le groupe R que dans les autres groupes. La méthode de Kaplan-Meier a montré que les taux sans événement cardiaque étaient plus faibles dans le groupe R que dans les autres groupes (P du test logarithmique par rangs < 0,001). À l'analyse multivariée selon le modèle à risques proportionnels de Cox, nous avons observé que le groupe R était un prédicteur indépendant des événements cardiaques (rapport de risque, 4,90; intervalle de confiance à 95 %, 2,23-10,74; P < 0,01). CONCLUSION: Chez les patients atteints d'IC, ceux qui avaient des ondes V inversées avaient une pression plus élevée de l'oreillette droite et étaient exposés à un risque plus élevé de pronostic défavorable.

Shear Wave Dispersion Predicts Liver Fibrosis and Adverse Outcomes in Patients with Heart Failure.

BACKGROUND: It has been recently reported that liver stiffness assessed by transient elastography reflects right atrial pressure (RAP) and is associated with worse outcomes in patients with heart failure (HF). However, the relationship between shear wave dispersion (SWD, a novel indicator of liver viscosity) determined by abdominal ultrasonography and RAP, and the prognostic impact of SWD on HF patients have not been fully examined. We aimed to clarify the associations of SWD with parameters of liver function test (LFT) and right heart catheterization (RHC), as well as with cardiac events such as cardiac death and worsening HF, in patients with HF. METHODS: We performed abdominal ultrasonography, LFT and RHC in HF patients (n = 195), and followed up for cardiac events. We examined associations between SWD and parameters of LFT and RHC. RESULTS: There were significant correlations between SWD and circulating levels of direct bilirubin (R = 0.222, p = 0.002), alkaline phosphatase (R = 0.219, p = 0.002), cholinesterase (R = -0.184, p = 0.011), and 7S domain of collagen type IV (R = 0.177, p = 0.014), but not with RAP (R = 0.054, p = 0.567) or cardiac index (R = -0.015, p = 0.872). In the Kaplan-Meier analysis, cardiac event rate was significantly higher in the high SWD group (SWD ≥ 10.0 (m/s)/kHz, n = 103) than in the low SWD group (SWD < 10.0 (m/s)/kHz, n = 92; log-rank, p = 0.010). In the Cox proportional hazard analysis, high SWD was associated with high cardiac event rates (hazard ratio, 2.841; 95% confidence interval, 1.234-6.541, p = 0.014). In addition, there were no interactions between SWD and all subgroups, according to the subgroup analysis. CONCLUSIONS: SWD assessed by abdominal ultrasonography reflects liver fibrosis rather than liver congestion, and is associated with adverse prognosis in HF patients.
