RESUMEN

BACKGROUND: Little is known about spontaneous echo contrast (SEC) in the descending aorta (DASEC), occurring with or without SEC in the left atrium (LASEC), in the presence of atrial fibrillation (AF). We examined the clinical significance of DASEC, including its relationship with LASEC, in patients with nonvalvular AF. METHODS: Among 176 patients, 41 (23%) had DASEC and 51 (29%) had LASEC. The patients were divided into four groups based on the presence/absence of LASEC and DASEC, as Group A: no SEC (n = 107); Group B: only LASEC (n = 28); Group C: only DASEC (n = 18); and Group D: both types of SEC (n = 23). Clinical and echocardiographic parameters were compared between groups, and the possible determinants of DASEC were evaluated. RESULTS: Age, sex, and CHA2 DS2 -VASc score were similar in the four groups. Group D was more likely to have an increased LA diameter, decreased left ventricular ejection fraction (LVEF), and low LA appendage velocity compared to Group A. Group C had a smaller LA diameter and a higher appendage velocity than Group B. Multivariate logistic regression analysis, with age ≥75 years, female sex, LASEC, LVEF < 50%, and presence of DA plaques included as covariates, showed that LASEC (OR 4.22, 95% CI 1.92-9.26, p < .001) and LVEF < 50% (OR 2.70, 95% CI 1.12-6.52, p = .027) were significant determinants of DASEC. The prevalence of DASEC increased with increasing LASEC severity in order of none (13%), mild (28%), and dense (50%) (p < .001). CONCLUSIONS: In nonvalvular AF patients, DASEC is common, and it partly originates from LASEC, particularly in the presence of LV systolic dysfunction.

RESUMEN

End-stage renal disease (ESRD) is a common but profound clinical condition, and it is associated with extremely increased morbidity and mortality. ESRD can represent four major echocardiographic findings-myocardial hypertrophy, heart failure, valvular calcification, and pericardial effusion. Multiple factors interplay leading to these abnormalities, including pressure/volume overload, oxidative stress, and neurohormonal imbalances. Uremic cardiomyopathy is characterized by left ventricular (LV) hypertrophy and marked diastolic dysfunction. In ESRD patients on hemodialysis, LV geometry is changeable bidirectionally between concentric and eccentric hypertrophy, depending upon changes in corporal fluid volume and arterial pressure, which eventually results in a characteristic of LV systolic dysfunction. Speckle tracking echocardiography enabling to detect subclinical disease might help prevent future advancement to heart failure. Heart valve calcification also is common in ESRD, keeping in mind which progresses faster than expected. In a modern era, pericardial effusion observed in ESRD patients tends to result from volume overload, rather than pericarditis. In this review, we introduce and discuss those four echocardiography-assessed findings of ESRD, with which known and conceivable pathophysiologies for each are incorporated.

RESUMEN

Although the fibrosis-4 index (FIB-4) is associated with right atrial pressure or prognosis in acute heart failure (AHF), the prognostic impact of its reduction during hospitalization remains uncertain. We included 877 patients (age, 74.9 ± 12.0 years; 58% male) hospitalized with AHF. The reduction in FIB-4 was defined as: (FIB-4 on admission-FIB-4 at discharge)/FIB-4 on admission × 100. Patients were divided into low (< 1.0%, n = 293), middle (1.0-27.4%, n = 292), and high (> 27.4%, n = 292) FIB-4 reduction groups. The primary outcome was a composite of all-cause death or heart failure rehospitalization within 180 days. The median FIB-4 reduction was 14.7% (interquartile range - 7.8-34.9%). The primary outcome was observed in 79 (27.0%), 63 (21.6%), and 41 (14.0%) patients in the low, middle, and high FIB-4 reduction groups, respectively (P = 0.001). Adjusted Cox proportional-hazards analysis revealed that the middle and low FIB-4 reduction groups were associated with the primary outcome, independent of the pre-existing risk model including baseline FIB-4 ([high vs. middle] hazard ratio [HR]: 1.70, 95% confidence interval [CI]: 1.10-2,63, P = 0.017; [high vs. low] HR: 2.16, 95% CI 1.41-3.32, P < 0.001). FIB-4 reduction provided additional prognostic value to the baseline model, including well-known prognostic factors ([continuous net reclassification improvement] 0.304; 95% CI 0.139-0.464; P < 0.001; [integrated discrimination improvement] 0.011; 95% CI 0.004-0.017; P = 0.001). Additionally, the combination of the reduction in FIB-4 and brain natriuretic peptide was useful for risk stratification. In conclusion, among patients hospitalized with AHF, a greater FIB-4 reduction during hospitalization was associated with better prognoses.

RESUMEN

The association between polypharmacy/multiple drug use (MDU) and prognosis in patients hospitalized with heart failure (HF) is unclear. It is also unknown whether the prognostic values of MDU vary depending on the presence/absence of a previous history of HF and preserved/reduced left ventricular ejection fraction (LVEF). We analyzed consecutive 1,034 patients hospitalized with HF (age, 74.9 ± 11.5 years; 58.7% male). MDU was defined as ≥5 drugs at discharge. The primary endpoint was a composite of all-cause death and HF readmission. MDU was observed in 695 patients (67.2%). Patients with MDU use had higher prevalences of a previous history of HF, reduced LVEF, and comorbidities than those without MDU. Cox proportional hazard analysis showed that MDU was significantly associated with the primary endpoint after adjustment for possible confounders (hazard ratio [HR], 1.36; 95% confidence interval [CI], 1.03-1.79; P = 0.030). There was significant interaction between the presence/absence of a history of HF and the prognostic impact of MDU (HF history [-]: HR, 0.86; 95% CI, 0.54-1.40; P = 0.553; HF history [+]: HR, 1.72; 95% CI, 1.16-2.55; P = 0.007; P for interaction = 0.005). However, there was no significant interaction between preserved/reduced LVEF and the prognostic impact of MDU (P for interaction = 0.274). In conclusion, MDU at discharge is an independent risk factor for the composite of death or HF readmission in patients hospitalized with HF. We observed a significant interaction between the presence of de novo versus recurrent HF and the prognostic value of MDU.

RESUMEN

The left atrial appendage (LAA) is considered not only to be the most frequent site of thrombus formation, but also to play a pivotal role in maintaining normal cardiac function. Transesophageal echocardiography (TEE) is widely used to assess LAA function. The LAA flow velocity has been used as a surrogate for LAA function, and it varies with multiple interrelated factors including age, hemodynamics, type of arrhythmia, and antiarrhythmic interventions. Relatively great importance of LAA function is involved with intraatrial thrombus formation and subsequent thromboembolism, and thus, understanding of characteristics and behaviors of the LAA under various clinical conditions may help determine strategies against atrial thrombosis. Also, techniques other than TEE-derived Doppler to assess LAA function, such as tissue Doppler imaging, have been proposed. In this review, we introduce clinical and echocardiographic correlates of LAA function, the LAA flow velocity in particular, its significance, and how to interpret functional patterns of the LAA each relevant to specific clinical settings.

RESUMEN

The fibrosis-4 index, albumin-bilirubin score and neutrophil-lymphocyte ratio are all prognostic markers in patients with heart failure. Recently, the FAN score, which includes all 3 of these markers, was developed as a useful risk stratification tool in patients with cancer. However, its cut-off values have not been validated for heart failure. We aimed to investigate the optimal cut-off and prognostic values of the FAN score in patients with heart failure. We analyzed 669 consecutive patients hospitalized with heart failure (age, 75.8 ± 11.3 years). Their median values of the fibrosis-4 index, albumin-bilirubin score, and neutrophil-lymphocyte ratio at discharge were 2.12, -2.25, and 2.41, respectively. The FAN score for heart failure (HF-FAN score) was calculated using these median values. The primary outcome was a composite of all-cause death and heart failure rehospitalization. Patients were divided into 4 groups according to HF-FAN scores of 0 (n = 112), 1 (n = 231), 2 (n = 242) and 3 (n = 84). Patients with HF-FAN scores of 3 were older, had higher brain natriuretic peptide levels, and larger inferior vena cava diameters. Kaplan-Meier analysis showed a direct correlation between higher HF-FAN scores and occurrence of the primary endpoint (log-rank P < 0.001). Cox proportional hazard analysis revealed a higher HF-FAN score was significantly associated with a worse prognosis even after adjustment for possible prognostic factors. Changing from the FAN score to HF-FAN score provided significant continuous net reclassification improvement. In conclusion, the HF-FAN score at discharge was useful for risk stratification in patients hospitalized with heart failure. The HF-FAN score might be more suitable for patients with heart failure than the FAN score.

RESUMEN

BACKGROUND: Thrombogenic milieu (TM) within the left atrium plays a pivotal role in the pathogenesis of thromboembolic events, for which anticoagulation treatment is indicated typically on the mandatory basis. Little is known, however, about which regimen of anticoagulation, warfarin or direct oral anticoagulants (DOACs), is more likely associated with TM. We evaluated relative relationship of the two treatment options with concurrently-observed TM in patients with nonvalvular atrial fibrillation (AF) who underwent transesophageal echocardiography. METHODS: TM was defined as the presence of either left atrial spontaneous echo contrast (SEC) or thrombus, or both. To determine which regimen was more likely related to TM, we firstly compared the prevalence of TM in 208 patients taking warfarin (Warfarin group) versus 486 patients taking DOACs (DOAC group); and secondly, did the same analysis after propensity score matching. RESULTS: Warfarin group was more likely associated with TM compared with DOAC group (46% vs 29%, p < 0.001). Similar findings were observed for dense SEC (18% vs 7%, p < 0.001) and thrombus (4% vs 1%, p = 0.057). The propensity score matching (198 patients for each group), where several baseline parameters were matched including age, gender, chronicity of AF, estimated glomerular filtration rate and B-type natriuretic peptide as well as the left ventricular ejection fraction, resulted in similar findings to the original groups (TM, 47% vs 32%, p = 0.002; dense SEC, 18% vs 7%, p = 0.001; thrombus, 4% vs 1%, p = 0.047). CONCLUSIONS: This study may strengthen the data on randomized trials that DOACs are superior to warfarin in preventing thromboembolic events in nonvalvular AF patients. Further studies are required to elucidate the details behind this difference.

RESUMEN

AIMS: Recently, liver fibrosis markers, such as the fibrosis-4 index (FIB-4), have been shown to be associated with prognosis in patients with heart failure. The fibrosis-5 (FIB-5) index, which assesses albumin, alkaline phosphatase, aspartate transaminase, alanine aminotransferase and platelet count, is a simple liver fibrosis marker that was reported to be superior to FIB-4 for differentiation of liver fibrosis. This study aimed to compare the prognostic value of FIB-4 and FIB-5 in patients with heart failure. METHODS AND RESULTS: The FIB-4 and FIB-5 scores were calculated at discharge in 906 patients hospitalized with heart failure. The patients were stratified into three groups based on their FIB-5 scores: low (n = 303), middle (n = 301), and high (n = 302) FIB-5 groups. The primary endpoint was a composite of cardiac death or rehospitalization for heart failure. The low FIB-5 group was older and had larger inferior vena cava diameters and higher brain natriuretic peptide levels than the other two groups. The primary endpoint occurred in 156 (51.5%), 110 (36.5%), and 54 patients (17.9%) in the low, middle, and high FIB-5 groups, respectively (P < 0.001). On Cox proportional hazard analysis, the low FIB-5 was independently associated with the primary endpoint after adjustment for confounding factors. The association was consistent in both patients with preserved and reduced left ventricular ejection fraction (LVEF), and there was no significant interaction between LVEF phenotypes in terms of the prognostic impact of FIB-5 (P for interaction = 0.311). FIB-5 was superior to FIB-4 as a prognostic indicator of the primary endpoint (continuous net reclassification improvement, 0.530; 95% confidence interval [CI], 0.399-0.662; P < 0.001; integrated discrimination improvement, 0.072; 95% CI, 0.057-0.088; P < 0.001). CONCLUSIONS: The FIB-5 is a useful risk stratification marker with better prognostic value than FIB-4 in patients hospitalized with heart failure.

RESUMEN

BACKGROUND: A lack of adherence and inadequate self-care behaviours are common reasons for recurrent hospitalizations among patients with heart failure (HF). Although patients recognize the importance of HF self-care, it is sometimes difficult to correct their behavioural patterns. Motivational interviewing is a communication technique to resolve ambivalence towards changing behaviour, and it has been widely used to promote behavioural changes and improve outcomes in various chronic diseases. We described a case of advanced HF with reduced ejection fraction in which motivational interviewing lead to stabilize the patient's condition. CASE SUMMARY: A 33-year-old man was diagnosed with dilated cardiomyopathy who experienced repeated episodes of HF requiring hospitalization despite optimal guideline-based HF treatment. Transthoracic echocardiography disclosed a severely reduced left ventricular (LV) contraction (LV ejection fraction 18%) and cardiopulmonary exercise testing disclosed markedly reduced functional capacity and increased ventilatory response (peak VO2 of 10.7 mL/min/kg, predicted peak VO2 of 34.7% and VE/VCO2 slope of 35.2). In this case, poor adherence to self-care such as excessive fluid intake and excessive daily activities after hospital discharge was the main cause of recurrent hospitalization for HF. Despite repeated patient education to correct his diet and lifestyle, he could not change his lifestyle behaviour. However, motivational interviewing dramatically helped stabilize the patient's condition and prevent HF re-hospitalization. DISCUSSION: In general, patients with advanced HF and reduced ejection fraction despite optimal medical therapy should be evaluated to assess their eligibility of cardiac transplantation or palliative care. Motivational interviewing might represent a new therapeutic approach for stabilizing and preventing HF through self-care behavioural changes, even in patients with advanced HF and severely reduced ejection fraction.

RESUMEN

BACKGROUND The left atrial appendage (LAA) has considerable variations in its size, shape, and spatial relationship with other cardiac structures. Absence of the LAA is a congenital cardiac condition usually identified by an imaging modality intended for other purposes. Absence of the LAA has been described in a total of 19 case reports so far; however, no cases of "hypoplastic" LAA in a real sense have ever been reported. CASE REPORT We herein report a case of hypoplastic, but not truly absent, LAA in a 76-year-old man scheduled for catheter ablation against atrial flutter. Preprocedural transesophageal echocardiography (TEE) performed in this patient to exclude intracardiac thrombosis failed to detect the LAA, although Doppler color-flow mapping revealed a jet signal spewed out into the main LA around where the LAA would be located. The LAA was also not detectable by routinely developed tomographic images from computed tomography (CT) angiography. Eventually, however, the multiplanar reconstruction into 3-dimensional volume rendering via the CT angiography identified a very small LAA. Those findings by TEE and CT led to a diagnosis of hypoplastic LAA. CONCLUSIONS Hypoplastic LAA should be kept in mind when considering LAA interventions as well as anticoagulation treatment. Multiple imaging modalities are necessary to recognize morphological aberration of the LAA.

RESUMEN

Sarcoidosis is a multisystem granulomatous disease of unknown cause. With cardiac sarcoidosis (CS), patients represent a wide range of cardiac manifestations from subtle to overt morphological and functional abnormalities. The advent of ultrasound technologies has enabled to identify not only typical findings to CS such as basal thinning of the ventricular septum, but also subclinical myocardial alterations. Based on our recent experiences, we currently introduce a variety of myocardial manifestations evaluated by echocardiography on seven CS patients being selected. Most of the patients exhibited typical cardiac involvement and the remaining fairly unusual.

RESUMEN

The spleen is associated with inflammation, and the size of the spleen is affected by hemodynamic congestion and sympathetic stimulation. However, the association between splenic size and prognosis in patients with heart failure remains unknown. Between January 2015 and March 2017, we analyzed 125 patients with acute decompensated heart failure who were assessed by computed tomography (CT) on the day of admission. The spleen was measured by 3-dimensional CT and then the patients were assigned to groups according to their median splenic volume indexes (SpVi; splenic volume/body surface area). We then compared their baseline characteristics and rates of readmission for heart failure after one year. The median SpVi was 63.7 (interquartile range: 44.7-95.3) cm3/m2. Age did not significantly differ between the groups. Patients with a high SpVi had more significantly enlarged left atria and left ventricles. Multiple regression analysis identified significant positive correlations between SpVi and posterior wall thickness as well as left ventricular mass index. Kaplan-Meier analysis revealed lower event-free rates in the patients with a high, than a low SpVi (P = 0.041, log-rank test). After adjustment for potential cofounding factors, SpVi was independently associated with readmission for heart failure (Hazard ratio, 2.25; 95% confidence interval, 1.01-5.02; P = 0.047). In conclusion, increased splenic volume is independently associated with readmission for heart failure among patients with acute decompensated heart failure.

RESUMEN

BACKGROUND Left atrial appendage (LAA) ostial stenosis is a rare cardiac condition usually identified by transesophageal echocardiography (TEE). LAA ostial stenosis can be classified into 2 types: one is idiopathic and the other is a complication after incomplete surgical LAA ligation. The former one is even rarer and only 12 cases have previously been reported. CASE REPORT An asymptomatic young woman was found at a medical checkup to have an abnormal jet signal in the left atrium on transthoracic echocardiography. TEE revealed that the abnormal signal originated from a narrowed orifice of the LAA. There were no other cardiac abnormalities in this woman. Unlike the previously reported cases, our case had LAA ostial stenosis detected by transthoracic echocardiography but not by TEE. CONCLUSIONS We describe a case of anatomic narrowing of the LAA orifice in a young woman. This was a first-ever case of idiopathic LAA ostial stenosis that was detected by transthoracic echocardiography. Because of the very small number of such cases reported, it remains unknown whether anticoagulation is required to prevent intra-atrial thrombus formation.

RESUMEN

Pesticides to protect crops from pests are subject to rigorous risk assessment before registration in Japan. However, further information needs to be collected regarding the assessment of impacts on the natural environment. In particular, nitrifying bacteria play a role in converting ammonium salts to nitrates in soil. However, there is limited research covering the effects of insecticides on nitrification, despite several fungicides and herbicides have an inhibitory effect on nitrifying bacteria. Therefore, we investigated the effect of pesticides on the nitrification when applied to soil. The application of both pesticides promoted ammonia oxidation, and suppressed nitrite oxidation in a high-concentration treatment of dinotefuran. In addition, it was clarified that the diversity and species richness of soil bacteria was significantly reduced when the pesticides were applied to the soil, and that the specific soil bacteria (Metyhlotenera spp.) dominated the application of the pesticides.

RESUMEN

Current echocardiography techniques have allowed more precise assessment of cardiac structure and function of the several types of cardiomyopathies. Parameters derived from echocardiographic tissue imaging (ETI)-tissue Doppler, strain, strain rate, and others-are extensively used to provide a framework in the evaluation and management of cardiomyopathies. Generally, myocardial function assessed by ETI is depressed in all types of cardiomyopathies, non-ischemic dilated cardiomyopathy (DCM) in particular. In hypertrophic cardiomyopathy (HCM), ETI is useful to identify subclinical disease in family members of HCM, to differentiate HCM from other conditions causing cardiac hypertrophy and to predict cardiac events. ETI also for HCM allows addressing the mechanism behind left ventricular outflow tract obstruction and its improvement after therapeutic options. ETI provides cardiac amyloidosis with unique and specific findings such as "apical sparing." Nevertheless, ETI does not seem to provide as much information amenable to histological findings as recently emerging techniques of cardiac magnetic resonance imaging. This review introduces usefulness of ETI and some other ultrasound techniques for detecting clinical and subclinical characteristics of cardiomyopathies, focusing on DCM, HCM, and cardiac amyloidosis.

RESUMEN

Elevated liver fibrosis markers are associated with worse prognosis in acute heart failure (AHF). The aspartate aminotransferase to alanine aminotransferase ratio (AAR) is one such fibrosis marker, and low ALT is a surrogate marker of malnutrition. Here, we evaluated the association between AAR and nutritional status and prognosis in patients with AHF. Consecutive 774 patients who were admitted due to AHF were divided into 3 groups according to AAR at discharge: first tertile, AAR<1.16 (n = 262); second tertile, 1.16≤AAR<1.70 (n = 257); and third tertile, AAR≥1.70 (n = 255). Nutritional indices and a composite of all-cause death or HF rehospitalization were compared in the 3 tertiles. Patients in the third AAR tertile were older and had lower body mass index than patients in other AAR tertiles. A higher AAR was associated with worse nutritional indices (i.e., controlling nutritional status score, geriatric nutritional risk index, and prognostic nutritional index). Clinical outcome rates significantly increased along AAR tertiles (first tertile, 28%; second tertile, 43%; third tertile, 58%, p < 0.001). Cox proportional hazards models including potential prognostic factors revealed high AAR was an independent prognostic factor of AHF. In conclusion, AAR at discharge may be associated with nutritional status and worse clinical outcomes in patients with AHF.

RESUMEN

BACKGROUND: Left atrial spontaneous echo contrast (LASEC) is common in patients with atrial fibrillation (AF), although scarce information exists on LASEC occurring in nonvalvular AF patients who have low thromboembolic risk scores. We therefore examined prevalence and determinants of LASEC under low CHADS2 or CHA2DS2-VASc scores in these patients. METHODS: Among 713 patients who underwent transesophageal echocardiography, 349 with a CHADS2 score < 2 (CHADS2 group) (93 women, mean age 65 years) and 221 with a CHA2DS2-VASc score < 2 (CHA2DS2-VASc group) (39 women, mean age 62 years) were separately examined for clinical and echocardiographic findings. RESULTS: LASEC was found in 77 patients of CHADS2 group (22%) and in 41 of CHA2DS2-VASc group (19%). Multivariate logistic regression analysis, adjusted for several parameters including non-paroxysmal AF, LA enlargement (LA diameter ≥ 50 mm), left ventricular (LV) hypertrophy, and an elevated B-type natriuretic peptide (BNP) (BNP ≥200 pg/mL) revealed that for CHADS2 group, non-paroxysmal AF (Odds ratio 5.65, 95%CI 3.08-10.5, P < 0.001), BNP elevation (Odds ratio 3.42, 95%CI 1.29-9.06, P = 0.013), and LV hypertrophy (Odds ratio 2.26, 95%CI 1.19-4.28, P = 0.013) were significant independent determinants of LASEC, and that for CHA2DS2-VASc group, non-paroxysmal AF (Odds ratio 3.38, 95%CI 1.51-7.54, P = 0.003) and LV hypertrophy (Odds ratio 2.53, 95%CI 1.13-5.70, P = 0.025) were significant independent determinants of LASEC. CONCLUSIONS: LASEC was present in a considerable proportion of patients with nonvalvular AF under low thromboembolic risk scores. Information on AF chronicity, BNP, and LV hypertrophy might help identify patients at risk for thromboembolism, although large-scale studies are necessary to confirm our observations.

RESUMEN

BACKGROUND: Tissue Doppler imaging (TDI)-derived atrial electromechanical delay (AEMD) has been reported to be useful for detecting paroxysmal atrial fibrillation (PAF). However, its usefulness remains unknown when analyzed along with patients seemingly at high-risk for AF as controls. From this standpoint, we investigated whether AEMD would be of use for identifying patients with PAF. METHODS: We retrospectively analyzed TDI recordings to obtain AEMD in 63 PAF patients. Thirty-three patients with multiple cardiovascular risk factors (MRFs) but without history of AF and 50 healthy individuals served as disease and healthy controls, respectively. AEMD was defined as the time-interval between the electrocardiogram P-wave and the beginning of the spectral TDI-derived A' for the septal (septal EMD) and lateral (lateral EMD) sides of the mitral annulus. RESULTS: There was no significant difference in the left atrial volume index between PAF patients and disease controls (28 ± 9 mL/m2 vs. 27 ± 5 mL/m2). PAF patients had longer AEMD, particularly for the lateral EMD (75 ± 23 ms), compared with disease (62 ± 22 ms, P = 0.009) and healthy (54 ± 24 ms, P < 0.001) controls. Multivariate logistic regression analysis revealed that the lateral EMD (OR 1.25, 95%CI 1.03-1.52, P = 0.023), along with the left atrial volume index (OR 2.25, 95%CI 1.44-3.51, P < 0.001), was one of the significant independent associates of identifying PAF patients. CONCLUSIONS: This cross-sectional study indicates that even analyzed together with MRFs patients, AEMD remains useful for identifying patients at risk for AF. Our results need to be confirmed by a large-scale prospective study.

RESUMEN

Malnutrition and systemic inflammation are associated with poor outcomes in patients with heart failure. Recent studies have reported that the advanced lung cancer inflammation index (ALI), derived from the body mass index (BMI), serum albumin level, and neutrophil-to-lymphocyte ratio (NLR), is associated with poor prognosis in several types of cancers. Each marker is also known to prognostic factor of heart failure. Therefore, we hypothesized that ALI may be useful for determining the prognosis of patients with acute decompensated heart failure (ADHF). We reviewed survival in 381 consecutive patients (age, 73.1 ± 11.4 years, 59% men) who were hospitalized for ADHF and discharged. ALI at discharge, calculated as BMI × albumin level/NLR, was used to divide the patients into tertiles (ALI < 23.88, 23.88 ≤ ALI < 42.43, and ALI ≥ 42.43). The patients were also stratified into six groups according to the ALI tertiles and median concentration (177 pg/mL) of brain natriuretic peptide (BNP). The primary endpoint comprised all-cause mortality and readmission because of heart failure. The median follow-up duration was 363 days (interquartile range: 147-721 days), and 166 patients (44%) experienced the primary endpoint. Kaplan-Meier analysis showed that the event rate decreased progressively from the first to the third ALI tertile (52%, 48%, and 31%, respectively; p = 0.0013). In a multivariate Cox proportional hazards model, the first tertile was an independent prognostic factor for the primary endpoint (third vs. first tertile: hazard ratio, 0.57; 95% confidence interval, 0.34-0.95; p = 0.031). The hazard ratio for the primary endpoint for the patients with high BNP and first tertile ALI relative to the patients with low BNP and third tertile ALI was 5.3 (95% confidence interval, 2.9-9.5; p < 0.001). ALI at discharge, a novel and simple index of nutrition and inflammation, may be useful for risk stratification and predicting the prognosis of patients with ADHF.
