Urine albumin-to-creatinine ratio on admission predicts early rehospitalization in patients with acute decompensated heart failure.

Detecting high-risk patients for early rehospitalization is crucial in heart failure patient care. An association of albuminuria with cardiovascular events is well known. However, its predictive impact on rehospitalization for acute decompensated heart failure (ADHF) remains unknown. In this study, 190 consecutive patients admitted due to ADHF between 2017 and April 2019 who underwent urinalysis were enrolled. Among them, 140 patients from whom urine albumin-to-creatinine ratio (UACR) was measured with spot urine samples on admission were further analyzed. The association between UACR and rehospitalization due to HF during 1 year after discharge was evaluated. The mean age of 140 participants was 77.6 years and 55% were men. Only 18% (n = 25) of patients presented with normoalbuminuria (UACR < 30 mg/g∙creatinine), whereas 59% (n = 83) and 23% (n = 32) showed microalbuminuria (UACR 30-300 mg/g·creatinine) and macroalbuminuria (UACR > 300 mg/g·creatinine), respectively. The level of UACR on admission was correlated with the risk of subsequent rehospitalization due to HF (p = 0.017). The receiver operating characteristic analysis indicated that the best cut-off values for the UACR and B-type natriuretic peptide (BNP) levels to predict ADHF rehospitalization were 50 mg/g·creatinine and 824 pg/ml, respectively. When the patients were divided into four groups using both cut-off values, the individual predictive impacts of UACR and BNP on rehospitalization were comparable. Patients with both elevated UACR and BNP levels had a higher rate of HF rehospitalization than those with elevated BNP levels alone (p < 0.05). The combination of both values enabled more accurate prediction of HF rehospitalization than BNP levels alone. In conclusion, UACR could be a new useful biomarker to predict HF rehospitalization in patients with ADHF, especially in combination with the levels of BNP, and should be further evaluated in a prospective study.

Clinical subsets associated with different anti-aminoacyl transfer RNA synthetase antibodies and their association with coexisting anti-Ro52.

OBJECTIVE: To characterize clinical features of polymyositis/dermatomyositis (PM/DM) patients with different anti-aminoacyl transfer RNA synthetase (ARS) antibodies and their association with anti-Ro52. METHODS: Autoantibodies in sera from 97 Japanese patients (36 PM, 56 DM, and 5 clinically amyopathic DM), who satisfied Bohan and Peter or modified Sontheimer's criteria, were characterized by immunoprecipitation and enzyme-linked immunosorbent assay. Clinical information was from medical records. Features associated with different anti-ARS and anti-Ro52 antibodies were analyzed. RESULTS: The prevalence of anti-ARS was similar to other studies (Jo-1, 22%; EJ, 4%; OJ, 1%; PL-12, 1%), except for a high prevalence of anti-PL-7 (12%), which allowed us to characterize patients carrying this specificity. Serum creatine kinase >3000 IU/l was less common in anti-PL-7-positive patients (57%) than anti-Jo-1-positive patients (18%) (p = 0.0328) and was not found in anti-EJ-positive individuals. Interstitial lung disease was common in anti-ARS-positive patients (97%) (p < 0.0001 vs. 48% in anti-ARS-negative). Anti-Ro52 antibodies were frequently detected with anti-ARS (59%) (57% in anti-Jo-1, 67% in anti-PL-7) (vs. 21% in anti-ARS-negative, p < 0.0002). Anti-Ro52 was associated with overlap syndrome (26%) (vs. 7% in anti-Ro52-negative, p = 0.0119). CONCLUSIONS: Patients with different anti-ARS in combination with anti-Ro52 appear to be associated with distinctive clinical subsets.

Plasma renin activity variation following admission predicts patient outcome in acute decompensated heart failure with reduced and mildly reduced ejection fraction.

Plasma renin activity (PRA) level at admission is reported to be a prognostic predictor of acute decompensated heart failure (ADHF) patients. Although PRA is affected during hospitalization by several factors including fluid volume and drug titration, whether the changes in PRA levels during hospitalization (ΔPRA) are associated with prognosis of ADHF patients are largely unknown. PURPOSE: Investigate the predictive impact of ΔPRA on the prognosis of ADHF patients with reduced ejection fraction (HFrEF) and mildly reduced ejection fraction (HFmrEF). METHODS: Retrospectively analyzed consecutive 116 HFrEF and HFmrEF patients admitted for ADHF. PRA measurements were acquired at admission and at discharge. The primary outcome was a composite of cardiovascular death and HF re-hospitalization. RESULTS: Out of 116 patients, 85 had PRA measurements both at admission and at discharge. Compared to admission, PRA level was significantly higher at discharge (0.8 (IQR 0.3-2.2) to 2.8 (IQR 1.0-7.2), p < 0.001). Tertiary groups ranked by PRA level on admission showed trend of poor prognosis in order of high, mid, and low PRA level (p = 0.07). On the contrary, PRA level at discharge significantly differentiated the prognosis and was poor in order of high, low, and mid (p = 0.026). Next, when the participants were divided into tertiary groups ranked by ΔPRA, prognosis worsened in the order of "minimal", "decreasing", and the "increasing" tier. Cubic splines analysis also indicate a similar tendency. CONCLUSIONS: In ADHF patients with HFrEF and HFmrEF, patients with minimal ΔPRA showed the better prognosis over the those with either increasing or decreasing.

Successful withdrawal of catecholamine with ivabradine administration in catecholamine-dependent heart failure.

Ivabradine is a heart rate (HR)-lowering agent that blocks hyperpolarization-activated cyclic nucleotide-gated channel in the sinus node without a negative inotropic effect on cardiac function. Here we report a case of catecholamine-dependent heart failure, who was intolerant to ß blockers, and successfully withdrew catecholamine by administering ivabradine. A 39-year-old male acute decompensated heart failure (ADHF) patient with severe systolic cardiac failure, refractory to diuretic and dobutamine treatment was transferred to our hospital. In addition to titration of dobutamine support, intra-aortic balloon pump, mechanical ventilation, and continuous hemodiafiltration therapy were initiated. These mechanical supports could stabilize ADHF and were removed. Upon stabilization of ADHF, we attempted to initiate a low dose of bisoprolol and taper dobutamine, but the patient could not tolerate even a low dose of bisoprolol nor tapering of dobutamine. Since his HR was consistently above 100 beats per minute and ivabradine was reported to improve stroke volume (SV), we initiated ivabradine, and his SV remarkably increased after initiation. Consequently, the dose of dobutamine was successfully tapered. Also, additional clinical advantage of ivabradine, assessed through hemodynamic parameters, appeared to be a reduction in afterload. .

Clinical utility of reticulocyte hemoglobin equivalent in patients with heart failure.

Anemia and iron deficiency (ID) are common in patients with heart failure (HF) and intravenous (IV) administration of iron to patients hospitalized for decompensated HF with ID improves outcome. The diagnosis of ID in routine practice is based on serum ferritin and transferrin saturation (TSAT) but both have limitations; alternatives should be considered. Reticulocyte hemoglobin equivalent (Ret-He) reflects iron content in reticulocytes but its clinical utility in patients with HF remains uncertain. We prospectively enrolled 142 patients hospitalized for decompensated HF. Sixty five percent had ID as defined in current international guidelines. Ret-He was directly correlated with serum iron and ferritin concentrations and with TSAT. There was a poor relationship between quartile of Ret-He and HF hospitalization or death but increases or decreases in Ret-He between admission and discharge were associated with a worse outcome. The clinical utility of Ret-He for identifying ID and predicting response to IV iron and prognosis for patients with HF requires further investigation.

Incidence and predictive factors for malignancies in 136 Japanese patients with dermatomyositis, polymyositis and clinically amyopathic dermatomyositis.

The aim of this study was to define the standardized incidence ratio (SIR) of malignancy and the potential risk factors of concomitant malignancies in patients with inflammatory myopathies, including clinically amyopathic dermatomyositis (CADM). A total of 145 patients diagnosed with either dermatomyositis/polymyositis (DM/PM) or CADM at our institute between 1984 and 2002 were enrolled in the study. The demographic, clinical and laboratory features of the patients at the time of DM/PM or CADM diagnosis were compared between patients with and without malignancies, respectively. Multivariate analysis by logistic regression was used to determine the independent risk factors for the development of malignancies in DM/PM patients. Malignancy was found in 17 of 70 patients with DM (24%), three of 15 patients with CADM (20%), and three of 51 patients with PM (6%). Gastric cancer (8/23) was the most common malignancy. Compared with general population, the SIR of malignancies was 13.8 (range 9.0-21.1). The patients who developed malignancies were older (61.5 vs. 51.1 years; P < 0.005), presented more often with dysphagia (61 vs. 15%; P < 0.0001) and were less likely to have the complication of interstitial lung disease (30 vs. 60%; P < 0.05). These features were independent predictive factors for developing malignancies in multiple logistic regression analysis. The results of our study confirm that CADM in addition to DM was associated with high rates of malignancy among our patient cohort.

Assessment of Microvasculature After Intervention as a Predictor of Wound Healing in Patients With Tissue Loss.

OBJECTIVES: This study investigated the correlation between vascular flow reserve (VFR) values and wound healing rate in patients with critical limb ischemia. BACKGROUND: Peripheral VFR may be useful for predicting complete wound healing after endovascular therapy (EVT). However, published reports included small numbers of patients from single centers and long-term outcomes remain unknown. METHODS: This was a prospective multicenter study that consecutively enrolled 104 patients (115 limbs) who received EVT for ischemic ulcerations. All lesions were treated with conventional balloon angioplasty. After EVT, VFR was measured using a pressure/temperature guidewire. The study endpoints were correlation between VFR values and wound healing rate at 3 months and 1 year. RESULTS: The median VFR was 2.9. A total of 110 and 104 limbs completed the 3-month and 1-year follow-up, respectively. The 3-month and 1-year wound healing rates were 49% and 76%, respectively. VFR was significantly associated with the 3-month and 1-year wound healing (p < 0.001 for both). The crude hazard ratios of VFR (per 2-fold increase) for the 3-month and 1-year wound healing were 2.6 (1.7 to 3.9) and 2.9 (2.0 to 4.2), respectively. The estimated median time to wound healing was 5.0 (3.2 to 7.2) months, 3.3 (2.8 to 4.9) months, and 2.5 (2.0 to 3.0) months, when the VFR value was 2.4, 2.9, and 3.9, respectively. CONCLUSIONS: Post-procedure VFR is significantly associated with wound healing. VFR, measured in the catheterization laboratory, is useful in clinical risk stratification for patients with critical limb ischemia after EVT. (Predictor of Wound Healing in Patients with Critical Limb Ischemia-Multicenter Prospective Study; UMIN000012746).

Effects of early diuretic response to carperitide in acute decompensated heart failure treatment: A single-center retrospective study.

BACKGROUND: Diuretic response is a strong predictor of outcome for admitted patients of acute decompensated heart failure (ADHF). However, little is known about the effects of early diuretic response to carperitide. METHODS: We retrospectively analyzed records of 85 patients hospitalized for ADHF who received carperitide as initial treatment and <40 mg furosemide during the early period. The eligible patients were divided into good diuretic responder (GR) group and poor diuretic responder (PR) group on the basis of median urinary volume. RESULTS: The PR group demonstrated older age, lower body mass index (BMI), lower estimated glomerular filtration rate, and higher blood urea nitrogen (BUN) level, left ventricular ejection fraction, and ß-blockers prescribed at baseline than the GR group. The incidence of worsening renal function (WRF) was significantly higher in the PR group than in the GR group. There was no correlation between early intravenous furosemide dose and urinary volume (Spearman correlation, ρ = 0.111, p = 0.312). Multivariate analysis showed that the statistically significant independent factors associated with poor diuretic response to carperitide were BMI (Odds ratio (OR) = 0.82, 95% confidence interval (CI) 0.68-0.94, p = 0.004) and BUN (OR = 1.07, 95%CI 1.01-1.15, p = 0.018). Kaplan-Meier analysis indicated a lower event-free rate in the PR group than in the GR group (log-rank, p = 0.007). CONCLUSIONS: BMI and BUN levels on admission were significant determinants of early poor diuretic response to carperitide. Early poor diuretic response to carperitide was associated with future poor outcomes.

Longterm survival and associated risk factors in patients with adult-onset idiopathic inflammatory myopathies and amyopathic dermatomyositis: experience in a single institute in Japan.

OBJECTIVE: To analyze clinical characteristics, survival, causes of death, and risk factors associated with mortality in patients with adult-onset idiopathic inflammatory myopathies (IIM) in Japan. METHODS: We retrospectively investigated 197 patients diagnosed with adult-onset IIM at our hospital from 1984 to 2009 according to Bohan and Peter criteria for polymyositis (PM)/dermatomyositis (DM) and modified Sontheimer's criteria for clinically amyopathic DM (ADM). RESULTS: Survival in the whole group at 1, 5, and 10 years was 85%, 75%, and 67%, respectively. Mortality in cancer-associated myositis was the worst (25% at 5 yrs), followed by clinically ADM (61% at 5 yrs) and primary DM (77% at 5 yrs). Primary DM had significantly low survival compared to primary PM (91% at 5 yrs; p = 0.0427). Among the 53 patients who died were 6 patients with ADM (11%) and 20 patients with primary DM (38%). Interstitial lung disease (ILD) was the main cause of death in clinically ADM (71%) and primary DM (60%), most of which occurred within the first few months. Fewer patients died in primary PM (9%) and overlap myositis (13%). Independent risk factors for death were older age (HR 1.031; 95% CI 1.009-1.053) and skin ulcers (HR 3.018; 95% CI 1.340-6.796) in the whole group and ILD with mild serum creatine kinase levels (< 500 IU/l; HR 3.537; 95% CI 1.260-9.928) in primary DM. CONCLUSION: Survival of clinically ADM and primary DM was low, mainly due to fatal ILD, compared to primary PM. Establishing therapeutic strategy for ILD may improve the survival in our patient population.
