RESUMO
Background and Objectives: Hypoxia-inducible factor prolyl hydroxylase (HIF-PH) inhibitors have been approved as an oral drug for treating anemia in chronic kidney disease (CKD). However, the clinical effect of HIF-PH inhibitors in patients with heart failure (HF) is unclear. Thus, this study investigated the effect of HIF-PH inhibitors in patients with HF and CKD. Materials and Methods: Thirteen patients with HF complicated by renal anemia who were started on vadadustat were enrolled. Clinical parameters were compared before and 1 month after vadadustat was started. Results: The mean left ventricular ejection fraction was 49.8 ± 13.9%, and the mean estimated glomerular filtration rate was 29.4 ± 10.6 mL/min/1.73 m2. The hemoglobin level was significantly increased (9.7 ± 1.3 mg/dL vs. 11.3 ± 1.3 mg/dL, p < 0.001), and the N-terminal prohormone of B-type natriuretic peptide was significantly decreased after the introduction of vadadustat [4357 (2651-15182) pg/mL vs. 2367 (1719-9347) pg/mL, p = 0.002]. Furthermore, the number of patients with New York Heart Association functional class ≥ 3 was also decreased after the introduction of vadadustat [8 (61.5%) vs. 1 (7.7%), p = 0.008]. No thromboembolic adverse events or new tumors were observed in any patient during the study period. Conclusions: The introduction of vadadustat in patients with HF complicated by renal anemia led to improvements in anemia and symptoms of HF.

Despite previous studies showing that patients with low systolic blood pressure (sBP) in heart failure with reduced ejection fraction (HFrEF) has a poor prognosis, it has few treatment options. This study aimed to investigate the efficacy and safety of sacubitril/valsartan (S/V) in HFrEF patients with hypotension. We included 43 consecutive HFrEF patients with sBP < 100 mmHg despite guideline-directed medical therapy for at least 3 months and who received S/V between September 2020 and July 2021. Patients admitted for acute heart failure were excluded and 29 patients were evaluated for safety endpoints. Furthermore, patients who performed non-pharmacological therapy or died within 1 month were excluded, finally, 25 patients were evaluated for efficacy endpoints. The mean initial S/V dose was 53.0 ± 20.5 mg/day and the mean dosage was increased to 84.0 ± 34.5 mg/day in 1 month. Serum N-terminal pro-B-type natriuretic peptide (NT-proBNP) values significantly decreased from 2200 [interquartile range (IQR): 1462-3666] pg/ml to 1409 (IQR: 964-2451) pg/ml. (p < 0.0001). No significant change in sBP occurred (pre-sBP: 93.2 ± 4.9 mmHg, post-sBP: 93.4 ± 9.6 mmHg, p = 0.91), and no patients discontinued the S/V due to symptomatic hypotension in 1 month after S/V initiation. S/V can be safely introduced in HFrEF patients with hypotension to reduce serum NT-proBNP values. Thus, S/V may be useful for the treatment of HFrEF patients with hypotension.

BACKGROUND: Clinical predictors for successful weaning of patients from Impella heart pump have not been clarified. We aimed to elucidate the relationship between pulmonary artery catheter (PAC) parameters at the time of Impella weaning and subsequent outcomes. METHODS: We enrolled consecutive patients who had received Impella for cardiogenic shock. PAC data were collected immediately before Impella weaning. Patients were classified as non-survivors if they died or required any mechanical circulatory support reintroduction within 30 days of weaning. RESULTS: Of 81 patients enrolled, 61 underwent Impella weaning. Of these, 16 were non-survivors. Predictive indicators of non-survival were high pulmonary artery wedge pressure (PAWP; hazard ratio [HR] per 5 mm Hg 1.97, 95% CI 1.35-2.80; p < 0.001), high mean pulmonary artery pressure (MPAP; HR per 5 mm Hg 1.90, 1.38-2.58; p < 0.001), and low cardiac power output (CPO; HR per 0.1 Watts 0.71, 0.52-0.92; p = 0.006). Cutoff values of PAWP 20 mm Hg, MPAP 22 mm Hg, and CPO 0.59 Watts showed strong associations with 30-day non-survival risk (low risk 8% in patients with low PAWP and high CPO or 4% in patients with low MPAP and high CPO; high risk 100% in patients with high PAWP and low CPO or 82% in patients with high MPAP and low CPO). CONCLUSIONS: PAWP or MPAP higher than the cutoff with CPO below the cutoff at Impella weaning were associated with worse outcomes. We proposed a risk classification model for successful Impella weaning using PAC.

Clinical parameters with correlation to diuretic effects after initiation of sodium-glucose cotransporter-2 (SGLT2) inhibitors are unclear. We aimed to identify the factors associated with the diuretic effect observed following the initiation of SGLT2 inhibitors in patients with diabetes having an acute heart failure (HF). Fifty-six patients included were hospitalized for acute HF with diabetes and started on SGLT2 inhibitors. Changes in urine volume (ΔUV) and blood/urine laboratory parameters before and during the first 4 days of therapy were evaluated. Data were prospectively obtained under clinically stable conditions after initial HF treatment. UV increased following the initiation of SGLT2 inhibitors [UV at baseline (BL): 1383 ± 479 mL/day; ΔUV over 4 days: + 189 ± 358 mL/day]. Multivariate analysis revealed no association between BL-hemoglobin A1c or BL-estimated glomerular filtration rate and ΔUV. Conversely, higher BL-fasting plasma glucose (FPG) and higher BL-urine N-acetyl-ß-D-glucosaminidase (NAG) were associated with a higher ΔUV. ΔUV was inversely associated with ΔFPG and ΔNAG, and positively associated with Δurinary sodium excretion. Elevated FPG and NAG both improved over 4 days of treatment. In conclusion, the diuretic effect of SGLT2 inhibitors was glycemia-dependent, and was associated with a reduction in elevated renal-tubular markers in hospitalized HF complicated with diabetes.

Re-worsening left ventricular ejection fraction (LVEF) is observed in some patients with dilated cardiomyopathy (DCM) despite initial improvements in LVEF. We analyzed cardiac outcomes and clinical variables associated with this re-worsening LVEF. A total of 180 newly diagnosed DCM patients who received only pharmacotherapy were enrolled. Echocardiography was performed after 6, 12, 24, and 36 months after initiation of pharmacotherapy. Patients were divided into three groups: (1) Improved: (n = 113, 63%), defined as those > 10% increase in LVEF after 12 months and no decrease (> 10%) between 12 and 36 months; (2) Re-worse: (n = 12, 7%), those with > 10% increase in LVEF after 12 months but with decrease (> 10%) between 12 and 36 months; and (3) Not-improved: (n = 55: 30%), those with no increase in LVEF (> 10%) after 12 months. Patients with re-worse group were older (P = 0.04) and had higher brain natriuretic peptide (BNP) levels after 12 months (P = 0.002) than those in the Improved group. Major cardiac events (sudden death, implantation of a ventricular assist device, and death due to heart failure,) were observed in 13 (7%) patients after 36 months of pharmacotherapy. Multivariate analysis revealed that the Re-worse group had a higher risk for cardiac events (hazard ratio 11.7, 95% confidence interval 1.9-90.7, P = 0.01) than the Improved group, but had a similar risk compared with the Not-improved group. Re-worsening LVEF was associated with poor cardiac outcomes in newly diagnosed DCM patients. Age and persistently high-BNP levels after improvement in LVEF were significantly associated with re-worsening LVEF.

An interaction between the intestine and cardiovascular disease has been suggested. We thought to clarify the association between intestinal conditions and clinical outcomes in patients with heart failure (HF). Hemodynamic parameters in intestinal vessels [superior mesenteric artery (SMA), inferior mesenteric artery (IMA), and portal vein (PV)] and average colon wall thickness (aCWT) from the ascending colon to sigmoid colon were evaluated in 224 hospitalized HF patients. Echocardiographic parameters and composite event rates (all-cause mortality, readmission for HF deterioration, major ventricular arrhythmias) were also examined. Higher PV congestion index (CI) and aCWT were observed in patients with New York Heart Association (NYHA) class III/IV. Higher PVCI [hazard ratio (HR) per + 1 standard deviation (SD) 1.50, p < 0.01] and aCWT (HR per + 1 SD 1.45, p < 0.01) were independently associated with higher composite event rates during the follow-up of 122 ± 68 days. None of SMA/IMA hemodynamic parameters were associated with NYHA class or composite event rates. Higher right ventricular end-diastolic dimension (38 ± 7 vs 34 ± 9 mm, p < 0.01) and lower tricuspid annual plane systolic excursion (15 ± 5 vs 19 ± 5 mm, p < 0.001) were observed in patients with higher PVCI (> 0.031 cm s) and aCWT (> 2.8 mm) relative to those in others. In conclusion, increased portal congestion and intestinal edema were associated with severe HF symptoms and poor outcomes in hospitalized HF patients, in addition to being associated with impaired right-sided cardiac function.

Decongestion is an important goal of heart failure (HF) management. Blood cell concentration is a recognized indicator for guiding decongestive treatment for HF. We aimed to assess the clinical impact of hemodilution and hemoconcentration after initial treatment in acute decompensated HF (ADHF) patients. We retrospectively evaluated hemoglobin levels and body weight obtained before admission, on admission, 3 days after admission, and at discharge in 102 consecutive patients admitted with ADHF. Patients were then stratified into hemodilution (n = 55) and hemoconcentration (n = 47) groups based on whether their hemoglobin levels decreased or increased, respectively, during the first 3 days after admission. From before admission to admission, hemoglobin levels decreased less in the hemodilution group (-0.16 ± 0.98 g/dL) than in the hemoconcentration group (-0.88 ± 1.11 g/dL) (P < 0.001); however, there was no significant difference in body weight (P≥ 0.05). More patients in the hemodilution group (85%) had grade III/IV pulmonary edema (Turner's criteria) compared with the hemoconcentration group (63%) (P < 0.01). Rate of readmission for HF within 180 days of discharge was higher in the hemodilution group (34%) compared with the hemoconcentration group (9%) (P < 0.01). Hemodilution after initial treatment for ADHF was associated with severe pulmonary edema at admission and higher readmission rates.

Our aim is to clarify the factors for early diagnosis of cardiac sarcoidosis (CS) in patients with complete atrioventricular block (CAVB) and its impact on cardiac function after corticosteroid therapy.A total of 15 CS patients with CAVB who underwent corticosteroid therapy were retrospectively analyzed. Patients were divided into two groups according to the time from the first CAVB onset to the diagnosis of CS. Clinical characteristics and outcomes were compared between the early diagnosis group (within 1 year; group E, n = 10) and the late diagnosis group (over 1 year; group L, n = 5).The history of extracardiac sarcoidosis (60 versus 0%, P = 0.0440) and abnormal findings on echocardiography (70 versus 0%, P = 0.0256) at the CAVB onset were significantly more frequent in group E than in group L. The change of left ventricular ejection fraction (LVEF) and brain natriuretic peptide (BNP) levels was significantly better in group E than in group L (0.8 ± 2.8 versus -32.4 ± 3.9%, P < 0.0001; -11.1 ± 16.0 versus 161.8 ± 35.8 pg/mL, P = 0.0013, respectively). After corticosteroid therapy, the LVEF and BNP levels were also significantly better in group E than in group L (53.3 ± 10.7 versus 37.0 ± 9.3%, P = 0.0128; 63.0 ± 46.4 versus 458.8 ± 352.0 pg/mL, P = 0.0027).The diagnosis may be delayed in CS patients with CAVB without history of extracardiac sarcoidosis. Abnormal findings on echocardiography contributed to the early diagnosis of CS. Therefore, the diagnosis of CS may be missed or delayed in patients without them. Time delay from the CAVB onset to the CS diagnosis may exacerbate the cardiac function.

Background: Clinical characteristics and the risk of cardiovascular events in patients with cardiac sarcoidosis (CS) according to the age of initial diagnosis are unclear. Methods: This study is a sub-analysis of the ILLUMINATE-CS registry, which is a retrospective, multicenter registry that enrolled patients with CS between 2001 and 2017. Patients were divided into three groups according to the tertile of age at the time of initial diagnosis of CS. The study compared the clinical background at the time of CS diagnosis and the incidence rate of cardiac events across age categories. Results: A total of 511 patients were analyzed in this study. In baseline, older patients were more likely to be female. History of hypertension, heart failure admission, and atrioventricular block were more common in patients with older age. There was no significant difference in the history of ventricular arrhythmias and left ventricular ejection fraction among all age groups. During a median follow-up period of 3.2 [IQR: 1.7-4.2] years, 35 deaths, 56 heart failure hospitalization, and 98 fatal ventricular arrhythmias was observed. The incidence rate of all-cause death and heart failure hospitalization was significantly higher in patients with older age (p < 0.001), while there was no significant difference in the incidence rate of ventricular arrhythmia among age groups (p = 0.74). Conclusions: In patients with CS, the risk of all-cause death and heart failure hospitalization was higher in older patients compared with other age groups; however, the risk of ventricular arrhythmia was comparable across all age groups.
RESUMO
Native T1 mapping is used to assess myocardial tissue characteristics without gadolinium contrast agents. The focal T1 high-intensity region can indicate myocardial alterations. This study aimed to identify the association between the native T1 mapping including the native T1 high region and left ventricular ejection fraction (LVEF) recovery in patients with dilated cardiomyopathy (DCM). Patients with newly diagnosed DCM (LVEF of < 45%) who underwent cardiac magnetic resonance imaging with native T1 mapping were included in the analysis. Native T1 high region was defined as a signal intensity of > 5 SD in the remote myocardium. Recovered EF was defined as a follow-up LVEF of ≥ 45% and an LVEF increase of ≥ 10% after 2 years from baseline. Seventy-one patients met the inclusion criteria for this study. Forty-four patients (61.9%) achieved recovered EF. Logistic regression analysis showed that the native T1 value (OR: 0.98; 95% CI: 0.96-0.99; P = 0.014) and the native T1 high region (OR: 0.17; 95% CI: 0.05-0.55; P = 0.002), but not late gadolinium enhancement, were independent predictors of recovered EF. Compared with native T1 value alone, combined native T1 high region and native T1 value improved the area under the curve from 0.703 to 0.788 for predicting recovered EF. Myocardial damage, which was quantified using native T1 mapping and the native T1 high region were independently associated with recovered EF in patients with newly diagnosed DCM.

BACKGROUND: Although cardiac resynchronization therapy (CRT) provided functional and clinical improvement in patients with heart failure (HF) and electrical intraventricular conduction disturbances, some patients had re-worsening left ventricular (LV) function after a favorable CRT response. We analyzed the clinical variables and cardiac outcomes associated with this re-worsening LV function after CRT. METHODS: In this study, 71 patients with CRT response who received CRT between 2006 and 2017 were included. CRT response was defined as a "≥ 10% improvement in LV ejection fraction (LVEF) on follow-up." Patients were classified into two groups: (i) persistent: (n = 48, 68%), defined as those with a CRT response and (ii) re-worsening: (n = 23, 32%), consisting of those who fell out of the definition of a CRT response after an initial CRT response. RESULTS: Half of the patients in the re-worsening group failed to maintain a CRT response from two years upwards. A longer duration from HF diagnosis to CRT implantation, nonspecific intraventricular conduction delay (NIVCD) on electrocardiogram at CRT implantation, and a lower increased LVEF at initial CRT response were independent predictors for the re-worsening group. Patients in the re-worsening group had a higher incidence rate for HF hospitalization and cardiac deaths, compared with those in the persistent group. CONCLUSION: One-third of CRT responders experienced re-worsening LVEF, which was associated with poor outcomes. CRT responders with NIVCD, longer HF duration, and a lower increased LVEF at initial CRT response should be monitored with caution.

A 44-year-old man diagnosed with idiopathic dilated cardiomyopathy was admitted to our hospital with acute decompensated heart failure. Seven years before this admission, the first introduction of medication resulted in left ventricular (LV) recovery, which was sustained for several years. However, the patient stopped taking his medication, resulting in worsening of the LV function. Despite the second introduction of medication, the LV function did not improve. We performed cardiac magnetic resonance imaging and an endomyocardial biopsy, which revealed the significant development of cardiac fibrosis that had not been present at the time of the initial diagnosis.

AIMS: Intestinal oedema is one of the manifestations associated with right-sided heart failure (HF), which is known to be associated with poorer patient outcomes. We attempted to reveal the association between intestinal oedema and diuretic resistance in hospitalized patients with acute HF. METHODS AND RESULTS: Among 213 hospitalized patients with acute HF, abdominal ultrasonography was performed under clinically stable conditions after initial HF treatments. The association among abdominal ultrasonographic parameters, maintenance doses of loop diuretics, and responsiveness to initial loop diuretic treatment was evaluated. Higher mean colon wall thickness (CWT) independently correlated with a higher dose of loop diuretics at enrolment (adjusted ß = 0.198, P = 0.0004). Increased mean CWT also correlated with poor response to oral loop diuretics as an initial treatment, whereas it did not correlate with the response to intravenous loop diuretics. Discrimination of non-responders to initial oral loop diuretics resulted in a sensitivity of 0.772 and a specificity of 0.733 using a mean CWT cut-off value of ≥3 mm. CONCLUSIONS: In hospitalized patients with acute HF, a strong correlation was identified among the severity of intestinal oedema, required quantities as maintenance loop diuretic doses, and poor responsiveness to oral loop diuretics at admission.

BACKGROUND: Prediction of atrioventricular block (AVB) resolution after steroid therapy in patients with cardiac sarcoidosis (CS) is difficult. METHODS: We identified 24 patients with CS and complete or advanced AVB receiving steroid therapy. AVB resolution was assessed by reviewing surface electrocardiogram and the percentage of ventricular pacing required on subsequent device interrogation reports. RESULTS: AVB resolution was noted in eight (33%) patients 1 year after receiving steroid therapy. Univariate Cox regression analysis demonstrated that left ventricular ejection fraction (LVEF) (hazard ratio [HR] 1.07, 95% confidence interval [CI] 1.01-1.14, P = .016), interval from recognized AVB to start of steroid therapy (HR 0.98, 95% CI 0.95-0.99, P < .001), and lysozyme (HR 1.51, 95% CI 1.12-2.19, P = .013) were significantly associated with resolution of AVB. Combination of area under the curve (AUC) of each variable that was significantly related to resolution of AVB (AUC, 0.969; 95% CI 0.921-1.000, P < .001) was tended to be higher compared with each variable alone. CONCLUSIONS: A shorter interval from recognition of AVB to start of steroid therapy, higher LVEF, and higher lysozyme levels were significantly associated with resolution of AVB after steroid therapy in patients with CS. The combination of each variable could be able to distinguish patients with resolution of AVB from those without.
RESUMO
BACKGROUND: Clinical significance of left atrial (LA) function and geometry in patients with dilated cardiomyopathy (DCM) remains uncertain. HYPOTHESIS: LA geometric parameters assessed by cardiac magnetic resonance (CMR) predict the prognosis in patients with DCM. METHODS: The present study included patients with DCM and sinus rhythm who underwent CMR between December 2007 and April 2018. LA volume was measured using CMR. LA sphericity index was computed as the ratio of the measured maximum LA volume by the volume of a sphere with maximum LA length diameter. RESULTS: We included 255 patients in this study. During the mean follow-up of 3.92 years, hospitalization for HF occurred in 37 patients. The LA sphericity index was significantly higher in patients with hospitalization for HF than in those without (0.78 ± 0.35 vs. 0.58 ± 0.18, p < .001). Multivariable Cox regression analysis identified a higher LA sphericity index as an independent predictor of hospitalization for HF. Patients were categorized based on the median of LA sphericity index. The Kaplan-Meier curve showed that patients with a high LA sphericity index (≥0.57) had a significantly higher risk of hospitalization for HF than those with a low LA sphericity index (<0.57). CONCLUSION: LA sphericity index was an independent predictor of hospitalization for HF. Assessment of LA geometric parameters might be useful for risk stratification in patients with DCM.

AIMS: This study aimed to evaluate the clinical parameters including late gadolinium enhancement (LGE) of cardiovascular magnetic resonance to predict re-worsening of left ventricular ejection fraction (LVEF) in patients with dilated cardiomyopathy (DCM). METHODS AND RESULTS: We included 138 patients with recent-onset DCM who had an LVEF <45% and underwent LGE of cardiovascular magnetic resonance imaging at diagnosis and echocardiography at the yearly follow-up [median 6 (4-8.3) years]. Initial LVEF recovery was defined as LVEF increase >10% from baseline, resulting in LVEF â§45% after treatment. The patients were divided into three groups: (i) improved (n = 83, 60%), defined as those with sustained LVEF â§45%; (ii) re-worsening (n = 39, 28%), those with >5% decrease and LVEF <45% after the initial LVEF recovery; and (iii) not-improved (n = 16, 12%), those without initial LVEF recovery. The primary endpoint was a composite of hospitalization for heart failure or sudden cardiac death. In baseline, LGE was observed in 70 patients. The LGE area was significantly larger in the re-worsening and not-improved groups than that in the improved group (P < 0.001). Loess curves of long-term LVEF trajectories showed that LVEF in the re-worsening group increased in the first 2 years and slowly declined thereafter. Multivariate logistic regression analysis demonstrated that LGE area [odds ratio (OR) 1.09, 95% confidence interval (CI) 1.03-1.16, P = 0.004], B-type natriuretic peptide (OR 1.49, 95% CI 1.05-2.21, P = 0.030) level at the initial recovery, and LVEF (OR 0.91, 95% CI 0.86-0.97, P = 0.004) at the initial LVEF recovery were independent predictors of re-worsening of LVEF. During a median follow-up of 2273 (interquartile range: 1634-3191) days, the primary endpoint was observed in 31 (22%) patients. Univariate Cox proportional hazards analysis demonstrated that the risk of experiencing the primary event in the re-worsening group was significantly higher (hazard ratio: 4.30, 95% CI 1.63-11.31, P = 0.003) than that in the improved group and was lower than that in the not-improved group (hazard ratio: 0.33, 95% CI 0.15-0.72, P = 0.006). CONCLUSIONS: Re-worsening of LVEF was observed in 28% of patients with recent-onset DCM who showed an initial improvement in LVEF. High LGE burden, higher B-type natriuretic peptide level, and lower LVEF at the initial LVEF recovery were independent predictors of re-worsening of LVEF in patients with DCM. Careful observation is recommended for patients with a high risk for re-worsening of LVEF, even in those with an initial LVEF recovery.

BACKGROUND: Patients with non-ischemic dilated cardiomyopathy (DCM) often show ischemia-like electrocardiographic findings. We aimed to elucidate the clinical impact of ischemia-like electrocardiographic findings in DCM, focusing on left ventricular reverse remodeling (LVRR). METHODS: We evaluated 195 patients hospitalized with heart failure (HF) and diagnosed with DCM. All patients underwent twelve-lead electrocardiography (ECG) and echocardiography during hospitalization and at the 2-year follow-up. RESULTS: During hospitalization, 152 (78%) patients experienced ischemia-like ECG findings (Minnesota codes I3, IV1-3, V1-3, or VII1); 43 patients (22%, non-ischemia-like group) did not experience these findings. Ischemia-like ECG findings were normalized during hospitalization in 64 patients (33%, transient-ischemia-like group) but were unchanged in 88 patients (45%, persistent-ischemia-like group). The highest rates of LVRR, defined as an increase in LV ejection fraction from ≥10% to a final value of ≥35%, along with decreased LV end-diastolic dimension of ≥10% during 2 years of follow-up, were shown in the transient-ischemia-like group (transient-ischemia-like group, 91%; persistent-ischemia-like group, 40%; non-ischemia-like-group, 51%; p < 0.001). The transient-ischemia-like group had lowest composite event rates, including readmission for HF, the detection of major ventricular arrhythmia, and sudden cardiac death. CONCLUSIONS: Normalization of ischemia-like ECG findings during the first HF treatments was associated with a higher occurrence of mid-term LVRR and favorable long-term outcome in patients with DCM.

Background: In patients with heart failure (HF), discontinued medical therapy because of adverse events (AE) is associated with high mortality. Patients with type 2 diabetes mellitus (T2DM) treated with sodium-glucose co-transporter 2 inhibitors (SGLT2i) have a lower risk of HF, but AE sometimes occur with the introduction of SGLT2i. In order to use SGLT2i safely in patients with HF, we investigated factors associated with AE following the introduction of SGLT2i. MethodsâandâResults: AE were defined as hypotension or an increase in serum creatinine ≥0.3 mg/dL by the fifth day after SGLT2i introduction. Sixty-four hospitalized patients with HF and T2DM treated with an SGLT2i were enrolled in this study. Patients were divided into 2 groups: with AE (n=13, 20.3%) and without (n=51, 79.7%). On logistic regression analysis, female sex, hemoglobin ≥15.2 g/dL, serum creatinine ≥1.05 mg/dL, and cardiac index on echocardiography ≤2.15 L/min/m2, were significantly associated with AE. A scoring system was constructed to predict AE according to significant variables (area under the receiver operating characteristic curve, 0.83; P<0.001) and the cut-off point was 2 points. Conclusions: Female sex, hemoconcentration, kidney injury, and low cardiac output were associated with AE at SGLT2i initiation in patients with HF. Using this scoring system, introduction of SGLT2i could be done safely in patients with HF.
