Plasma brain natriuretic peptide level on admission predicts long-term outcome in patients with non-traumatic subarachnoid hemorrhage.

INTRODUCTION: Non-traumatic subarachnoid hemorrhage (SAH) is a type of stroke that still has a high mortality rate. Some patients with SAH have electrocardiography (ECG) abnormalities or asymptomatic left ventricular apical ballooning, and requires intervention by cardiologists. However, the impact of cardiac abnormalities after SAH onset remains unclear. We investigated whether ECG abnormalities, myocardial damage, sympathetic nervous activity or echocardiographic left ventricular wall motion abnormalities (WMA) could provide additional risk stratification in patients with SAH. METHODS: We studied 118 SAH patients (78 women, age 63 ± 15) without a history of heart disease. Neurological grade (Hunt and Kosnik Grade) and clinical factors were evaluated. A standard 12-lead ECG, echocardiography and blood samples were obtained within 48 h after SAH onset. ECG abnormalities were defined as abnormal Q wave, ST elevation, giant T-wave inversion or QT prolongation. RESULTS: Twenty of 118 patients (17%) died during the follow-up (35 ± 31 months). Death was significantly associated with higher age (p < 0.0001), neurological grade (p < 0.0001), elevated BNP level (p < 0.0001), increased plasma norepinephrine levels (p < 0.0001) and WMA (p = 0.0070), while ECG abnormalities were not significantly associated. Neurological grade (p < 0.0001), age (p = 0.0047) and BNP (p = 0.0014, hazard ratio 1.0255 for each 1 pg/mL increase in BNP, 95%CI 1.0088 to 1.0499) were independently associated with death. Patients with BNP ≥ 96.6 had a higher risk of death (log- rank p < 0.0001). CONCLUSION: Plasma BNP might provide an additional risk stratification in patients with non-traumatic SAH that requires intervention by cardiologists for both its prevention management after onset.

Effective blood hemoglobin level to predict prognosis in heart failure with preserved left ventricular ejection fraction: results of the Japanese heart failure syndrome with preserved ejection fraction registry.

High prevalence of anemia in heart failure with preserved left ventricular ejection fraction (HFpEF) has been reported. However, little is known about the association of anemia and gender with prognosis in HFpEF patients. In addition, effective blood hemoglobin (Hb) level for prognosis in HFpEF patients remains largely unknown. In this study, we investigated the association between anemia, gender, and prognosis in 535 HFpEF patients enrolled in Japanese heart failure syndrome with preserved ejection fraction registry. Furthermore, we assessed effective blood Hb level to predict prognosis in HFpEF patients. According to the World Health Organization criteria, the prevalence rate of anemia on admission was about 70% in both male and female HFpEF patients. Kaplan-Meier analysis for all-cause mortality demonstrated that anemic patients had poor prognosis compared with non-anemic patients in both male and female HFpEF patients. Interestingly, multivariate analysis revealed that blood Hb level at discharge was an independent predictor of all-cause mortality in both male and female HFpEF patients. According to survival classification and regression tree analysis, blood Hb level at discharge of 9.4 g/dL for male and 12.3 g/dL for female was more accurate cutoff value to predict all-cause mortality in HFpEF patients. Anemia was implicated in poor prognosis in both male and female HFpEF patients. In particular, blood Hb level at discharge was an independent predictor of all-cause mortality in both male and female HFpEF patients. Effective cutoff value of blood Hb level at discharge to predict all-cause mortality was lower in male than in female HFpEF patients.

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.

Urinary composition predicts diuretic efficiency of hypertonic saline solution with furosemide therapy and heart failure prognosis.

Recently, we and other group have reported that furosemide administration along with hypertonic saline solution enhanced diuretic efficiency of furosemide. However, little is known about factors which associated with high diuretic efficiency by hypertonic saline solution with furosemide therapy. To identify predictors of diuretic efficiency in the hypertonic saline solution with furosemide therapy, we recruited 30 consecutive hospitalized heart failure (HF) patients with volume overload (77 ± 10 years, systolic blood pressure > 90 mmHg, and estimated glomerular filtration rate > 15 ml/min/1.73 m2). Hypertonic saline with furosemide solution, consisting of 500 ml of 1.7% hypertonic saline solution with 40 mg of furosemide, was administered continuously over 24 h. The patients were divided into two groups on the basis of 24-h urine volume (UV) after initiation of diuretic treatment ≥ 2000 ml (high urine volume: HUV) and < 2000 ml (low urine volume: LUV). The basal clinical characteristics of both groups were analyzed and the predictors of HUV after receiving the treatment were identified. There were not significant differences between two groups in baseline clinical characteristics and medication. Univariate logistic analysis revealed that blood urea nitrogen/creatinine ratio, urine urea nitrogen/creatinine ratio (UUN/UCre), fractional excretion of sodium, and tricuspid annular plane systolic excursion positively associated with HUV. Multivariate logistic regression analysis revealed that UUN/UCre at baseline was independently associated with HUV, and UUN/UCre best predicts HUV by the therapy with a cut-off value of 6.16 g/dl/g Cre (AUC 0.910, 95% CI 0.696-0.999, sensitivity 80%, specificity 87%). The Kaplan-Meier curves revealed significant difference for HF rehospitalization and death rate at 180 days between patients with UUN/UCre ≥ 6.16 g/dl/g Cre and those with UUN/UCre < 6.16 g/dl/g Cre (log-rank P = 0.0489). UUN/UCre at baseline strongly predicted of diuretic efficiency in the hypertonic saline solution with furosemide therapy, and was associated with HF prognosis.

Adaptive Servo-Ventilation Treatment Increases Stroke Volume in Stable Systolic Heart Failure Patients With Low Tricuspid Annular Plane Systolic Excursion.

We hypothesized that the effects of adaptive servo-ventilation (ASV) therapy were influenced by right-sided heart performance. This study aimed to clarify the interaction between the effects of ASV and right-sided heart performance in patients with stable heart failure (HF) with reduced ejection fraction (HFrEF).Twenty-six stable HF inpatients (left ventricular ejection fraction < 0.45, without moderate to severe mitral regurgitation (MR) were analyzed. Echocardiography was performed before and after 30 minutes of ASV. ASV increased stroke volume index (SVI) in 14 patients (30.0 ± 11.9 to 41.1 ± 16.1 mL/m2) and reduced SVI in 12 patients (36.0 ± 10.1 to 31.9 ± 12.2 mL/m2). Multivariate linear regression analysis revealed that tricuspid annular plane systolic excursion (TAPSE) before ASV was an independent association factor for (SV during ASV - SV before ASV)/LVEDV × 100 (%) (%ΔSV/LVEDV). ROC analysis of TAPSE for %ΔSV/LVEDV > 0 showed that the cut-off point was 16.5 mm. All patients were divided into 2 groups according to the TAPSE value. Although no significant differences were found in the baseline characteristics and blood tests, there were significant differences in tricuspid lateral annular systolic velocity, TAPSE, right atrial area, and right ventricular (RV) area before ASV between patients with TAPSE ≤ 16.5 mm and those with TAPSE > 16.5 mm. Interestingly, ASV reduced RV area and increased TAPSE in patients with TAPSE ≤ 16.5 mm, while it reduced TAPSE in those > 16.5 mm.ASV therapy has the potential to increase SVI in stable HFrEF patients with low TAPSE.

Right Ventricular Enlargement and Renal Function Are Associated With Smooth Introduction of Adaptive Servo-Ventilation Therapy in Chronic Heart Failure Patients.

Although adaptive servo-ventilation (ASV) therapy has beneficial effects on chronic heart failure (CHF), a relatively large number of CHF patients cannot undergo ASV therapy due to general discomfort from the mask and/or positive airway pressure. The present study aimed to clarify baseline patient characteristics which are associated with the smooth introduction of ASV treatment in stable CHF inpatients.Thirty-two consecutive heart failure (HF) inpatients were enrolled (left ventricular ejection fraction (LVEF) < 45%, estimated glomerular filtration rate (eGFR) > 10 mL/minute/1.73m2, and apnea-hypopnea index < 30/hour). After the patients were clinically stabilized on optimal therapy, they underwent portable polysomnography and echocardiography, and then received ASV therapy. The patients were divided into two groups: a smooth introduction group (n = 18) and non-smooth introduction group (n = 14). Smooth introduction of ASV treatment was defined as ASV usage for 4 hours and more on the first night. Univariate analysis showed that the smooth introduction group differed significantly from the non-smooth introduction group in age, hemoglobin level, eGFR, HF origin, LVEF, right ventricular (RV) diastolic dimension (RVDd), RV dp/dt, and RV fractional shortening. Multivariate analyses revealed that RVDd, eGFR, and LVEF were independently associated with smooth introduction. In addition, RVDd and eGFR seemed to be better diagnostic parameters for longer usage for ASV therapy according to the analysis of receiver operating characteristics curves.RV enlargement, eGFR, and LVEF are associated with the smooth introduction of ASV therapy in CHF inpatients.

Comparison of salt with low-dose furosemide and carperitide for treating acute decompensated heart failure: a single-center retrospective cohort study.

Hypertonic saline with furosemide has been proposed for a long time as an effective therapeutic option for the treatment of acute decompensated heart failure (ADHF). We previously reported the efficacy of continuous infusion of 1.7 % hypertonic saline plus low-dose furosemide in treatment for ADHF. Although this therapeutic strategy can be a useful option for effective decongestion in treatment for ADHF, there is no study that assesses the effect and safety of saline supplementation compared with standard therapy in Japan. The aim of this study was to investigate the efficacy, safety, and cost-effectiveness of 1.7 % hypertonic saline plus low-dose furosemide infusion compared with carperitide. We compared clinical outcomes, adverse events, and cost for patients receiving carperitide (carperitide group) with those for patients receiving 1.7 % hypertonic saline plus low-dose furosemide (salt group) during the initial hospitalization for ADHF. The cost analysis was performed on the basis of the previous report about cost-effectiveness of acute heart failure. A total of 175 ADHF patients received either carperitide (n = 111) or 1.7 % hypertonic saline plus low-dose furosemide infusion (n = 64) as initial treatment. There were no differences in length of hospital stay (27 ± 19 vs. 25 ± 16 day, p = 0.170) and infusion period (7.2 ± 6.1 vs. 8.4 ± 7.5 day, p = 0.474) between the two groups. The incidence of rehospitalization did not differ at 1 month (7.6 vs. 6.6 %, p = 1.000) and 1 year (36.8 vs. 37.7 %, p = 0.907) between the two groups. The Kaplan-Meier curves revealed no significant difference for 1 year all-cause mortality between the two groups (log-rank, p = 0.724). The single hospitalization cost was 95,314 yen lower and the yearly hospitalization cost 125,628 yen lower in the salt group compared with the carperitide group. Thus, intravenous 1.7 % hypertonic saline plus low-dose furosemide infusion is as effective as carperitide in terms of clinical outcome and is a cost-effective therapeutic strategy for the treatment of ADHF.

Recurrent coronary artery dissection of left main trunk initially presented with normal coronary angiography.

Although spontaneous coronary artery dissection (SCAD) is usually diagnosed by coronary angiography, diagnosis may be missed because of various presentations and imperfections of coronary angiography. We report a case of a 41-year-old female with pregnancy-related SCAD who presented with cardiac arrest. Initial coronary angiography was normal without intimal flap. Unexpectedly, 4 days after admission, SCAD in left main trunk was revealed with recurrent myocardial infarction. Intimal flap was sealed at the time of first angiography and this is an interesting point that made us report this case. SCAD is a rare but not negligible cause of not only acute myocardial infarction but also sudden cardiac arrest even if first coronary angiography is normal. .

Worsening of proteinuria caused by combination therapy of hypertonic saline and low-dose furosemide for treatment of acute decompensated heart failure with overt diabetic nephropathy.

A combination of hypertonic saline and furosemide has been proposed as a new therapeutic approach for treating acute decompensated heart failure (ADHF). The advantages of this combination have not only been demonstrated in ADHF but also in refractory ascites due to liver cirrhosis. However, the therapeutic effects of this regimen have never been evaluated in ADHF with overt diabetic nephropathy (ODN). Here, we present an interesting case of a 35-year-old patient admitted to our hospital for ADHF with shortness of breath and systemic edema, complicated with hypertension, type 2 diabetes, and ODN. Echocardiography showed left ventricular enlargement and diffuse hypokinesis, with ejection fraction of 33%. Urinary findings showed total proteinuria of 3597 mg/day during the first day of hospitalization. We initiated decongestion therapy with continuous infusion of hypertonic saline and furosemide. In spite of increased diuresis, edema remained the same and serum albumin decreased from 2.7 g/dl to 2.0 g/dl, and proteinuria increased up to 7344 mg/day. The amount of proteinuria and serum albumin level gradually recovered over time after cessation of the therapy. These data suggest that the combination therapy worsens glomerular hypertension and ODN. Therefore, hypertonic saline and furosemide combination therapy should not be recommended for patients with ODN. .

Hemodynamic response to sildenafil in patients with decompensated congestive heart failure can be predicted by deceleration time of transmitral flow.

AIM: How sildenafil acutely provides hemodynamic alterations in patients with decompensated congestive heart failure remains unknown. The aim of this study was to investigate whether myocardial and/or hemodynamic conditions affect hemodynamic response to sildenafil in patients with decompensated heart failure. METHODS AND RESULTS: Twenty-five consecutive patients with decompensated congestive heart failure were enrolled. The patients underwent echocardiography before and 1 hour after a single oral administration of sildenafil (20 mg). Sildenafil decreased pulmonary vascular resistance by 24% (P < 0.05), and increased left ventricular (LV) time-velocity integral by 17% (P < 0.05). Alteration of the ratio of peak velocity of early LV filling to early diastolic myocardial velocity (E/E'), an indicator of LV filling pressure, following administration of sildenafil, negatively associated with the deceleration time of early filling wave (DcT) at baseline. Patients with baseline DcT ≥ 200 milliseconds (n = 11) exhibited E/E' increase, whereas patients with baseline DcT <200 milliseconds (n = 14) exhibited E/E' decrease. CONCLUSIONS: Administration of sildenafil elevated LV filling pressure in decompensated heart failure patients with shortened deceleration time of early diastolic transmitral flow.

Intravenous salt supplementation with low-dose furosemide for treatment of acute decompensated heart failure.

BACKGROUND: Theoretically, salt supplementation should promote diuresis through increasing the glomerular filtration rate (GFR) during treatment of acute decompensated heart failure (ADHF) even with low-dose furosemide; however, there is little evidence to support this idea. METHODS AND RESULTS: This was a prospective, randomized, open-label, controlled trial that compared the diuretic effectiveness of salt infusion with that of glucose infusion supplemented with low-dose furosemide in 44 consecutive patients with ADHF. Patients were randomly administered 1.7% hypertonic saline solution supplemented with 40 mg furosemide (salt infusion group) or glucose supplemented with 40 mg furosemide (glucose infusion group). Our major end points were 24-hour urinary volume and GFR. Urinary volume was greater in the salt infusion group than in the glucose infusion group (2,701 ± 920 vs 1,777 ± 797 mL; P < .001). There was no significant difference in the estimated GFR at baseline. Creatinine clearance for 24 h was greater in the salt infusion group than in the glucose infusion group (63.5 ± 52.6 vs 39.0 ± 26.3 mL min(-1) 1.73 m(-2); P = .048). CONCLUSIONS: Salt supplementation rather than salt restriction evoked favorable diuresis through increasing GFR. The findings support an efficacious novel approach of the treatment of ADHF.

Combination of hypertonic saline and low-dose furosemide is an effective treatment for refractory congestive heart failure with hyponatremia.

Hyponatremia often associates with heart failure. Although severe salt restriction is generally recommended in heart failure treatment, it may promote hyponatremia which is a risk factor for increased morbidity and mortality in heart failure patients. Therefore, it is not yet clear whether correction of hyponatremia is an effective treatment in congestive heart failure with hyponatremia. We experienced a successful case of refractory congestive heart failure with hyponatremia treated with hypertonic saline and furosemide. A 45-year-old man, suffering from dilated cardiomyopathy, was admitted to our hospital for heart failure worsening with hyponatremia. We started diuretics therapy without correction of hyponatremia, but his clinical status of heart failure was not improved. Therefore, we additionally started to correct hyponatremia by continuous injection of hypertonic saline. The correction of hyponatremia increased urinary volume dramatically, and improved cardiac output and clinical status of heart failure. This case strongly suggests that combination of hypertonic saline and furosemide could enhance diuretic effect, and improve the clinical status of heart failure in congestive heart failure patients with hyponatremia. .
