An Infant with High-Output Heart Failure and Pulmonary Hypertension Resulting from a Giant Cutaneous Hemangioma.

We present the clinical course of an 8-month-old infant with a giant cutaneous hemangioma resulting in high-output heart failure and pulmonary hypertension. The lesion was successfully embolized and excised, with rapid resolution of heart failure and improvement in pulmonary hypertension.

High-output cardiac failure in the setting of iron deficiency anaemia: a case report.

We present a case of a child with high-output heart failure and severe iron deficiency anaemia-induced dilated cardiomyopathy managed with serial blood transfusions, preload and afterload reducing agents, inotropic therapies, and long-term iron supplementation. The complete resolution of echocardiogram findings of moderate enlargement of all cardiac chambers and moderately depressed left ventricular systolic function was achieved.

High-output heart failure following gunshot injury and traumatic arteriovenous fistula.

BACKGROUND: Heart failure due to high cardiac output rarely occurs. Few cases of post-traumatic arteriovenous fistula (AVF) as a cause of high-output failure were reported in the literature. METHODS: Herein, we report a case of 33-year-old male who was admitted to our institution due to symptoms of heart failure. He reported a gunshot injury of the left thigh 4 months earlier, when he had been shortly hospitalized and discharged 4 days later. Since the gunshot injury he had exertional dyspnea and left leg edema, so the diagnostic procedures were performed. RESULTS: Clinical examination revealed distended neck veins, tachycardia, slightly palpable liver, left leg edema, and thrill over the left thigh. Due to high clinical suspicion, duplex ultrasonography of the left leg was performed that verified femoral AVF. Operative treatment of AVF was made with prompt resolution of symptoms. CONCLUSIONS: This case wants to emphasize the importance of proper clinical examination, and duplex ultrasonography in all cases of penetrating injuries.

Infantile hemangiomatosis, a rare cause of high-output heart failure and pulmonary hypertension in the newborn baby: a case report.

Infantile hemangiomatosis is among the most common vascular tumours of childhood that is generally accepted as benign. Some cases may have multiple hemangiomas with organ involvement, especially of the liver. This case report will present the clinical and laboratory findings obtained during the treatment and follow-up of a 36-day-old female baby with hemangiomatosis with diffuse liver involvement, high-output heart failure, and pulmonary hypertension.

Scapular renal cell carcinoma metastasis as a cause of high-output heart failure: a case report.

BACKGROUND: High-output heart failure is a rare condition that occurs when the heart is unable to respond to a sustained increase in blood demand. On echocardiography, a cardiac index of > 4 L/min/m2 (or 6 L/min) is a clear indicator of this disorder. The causes of high-output heart failure vary, but they all involve peripheral vasodilation or arteriovenous shunting. Renal cell carcinoma is well known for producing high levels of angiogenic growth factors that induce arteriovenous shunts. The decrease in peripheral arterial resistance and the increase in venous return result in a permanent high cardiac output, followed by congestive heart failure. Single bone metastases of renal clear cell carcinoma tumours causing high cardiac output and heart failure symptoms have been reported less than ten times in the medical literature. CASE PRESENTATION: Before a right-shoulder painful lump with a murmur when auscultated, magnetic resonance imaging revealed a large scapular mass, which was biopsied and found to be a bone metastasis of renal cell carcinoma. Two months later, the patient developed heart failure for the first time. There was no evidence of cardiac disease on echocardiography. The cardiac output was 9.8 L/min and the cardiac index was 5.1 L/min/m2. Doppler ultrasound revealed numerous arteriovenous shunts in the large scapular metastasis and a right axillary artery flow of 24% of cardiac output. Sustained lower cardiac output was obtained following lesion-focused radiotherapy and systemic antiangiogenic treatment with axitinib and pembrolizumab. CONCLUSIONS: Herein, we present a unique case of high-output heart failure in a 70-year-old man diagnosed by echocardiography and upper-limb Doppler ultrasound in the context of metastatic renal cell carcinoma without pre-existing cardiac disease. We stress the potentially life-threatening hemodynamic consequences of hypervascularity associated with arteriovenous shunts within a single metastatic renal cell carcinoma implant, the importance of auscultating any progressing bone mass, and the utility of non-invasive Doppler ultrasound assessment in this setting.

An indolent cause of high-output heart failure in end-stage kidney disease-Application of the Nicoladoni-Israel-Branham test: A case report.

BACKGROUND: A hemodynamically significant arteriovenous fistula (AVF) in end-stage kidney disease (ESKD) causes a high flow state, resulting in pathologic cardiovascular remodeling, and deserves timely clinical recognition. CASE: A 55-year-old woman with history of ESKD with deceased donor kidney transplant with failing graft function and baseline creatinine of 2.8 mg/dl presented to the clinic with nocturnal cough, orthopnea, dyspnea on exertion and pedal edema. Physical exam was notable for large, aneurysmal right brachial AVF. Transthoracic echocardiography (TTE) revealed left ventricular (LV) enlargement and hypertrophy and elevated cardiac output (CO) of 10 L/min, raising a clinical concern for high-output heart failure. DECISION MAKING: A non-invasive assessment of the hemodynamic significance of the AVF was performed using a TTE. During temporary occlusion of the AVF, it was determined that about 27% of the resting CO was attributed to the AVF, suggesting hemodynamic significance. Nicoladoni-Israel-Branham sign was negative as there was no change in patient's heart rate, but this was potentially attributed to beta-blockade and chronic loading conditions. She underwent AVF banding and 2-month later her presenting symptoms resolved, and a TTE showed a decrease in resting CO of 7.6 L/min with normalization of LV size. CONCLUSION: This case highlights several teaching points. Firstly, in patients with ESKD, a large AVF can contribute to a high CO state resulting in maladaptive cardiovascular remodeling. Secondly, TTE evaluation of the hemodynamic contribution of an AVF can be performed with the application of the Nicoladoni-Israel-Branham sign. Finally, some experts recommend pre-emptive banding or ligation of AVF after successful kidney transplantation as this has been shown to have symptomatic and cardiovascular benefits.

A BERIBERI UNHEALTHY LATTE: ENCEPHALOPATHY AND SHOCK FROM SEVERE NUTRITIONAL DEFICIENCY.

BACKGROUND: Thiamine deficiency is an uncommon cause of severe illness in the United States that can lead to significant morbidity because of high-output cardiac failure, peripheral neuropathy, and permanent neurologic impairment. We report the case of a middle-aged woman with extreme malnutrition caused by complications of Roux-en-Y gastric bypass (RYGB) surgery who presented with signs and symptoms of severe thiamine deficiency and septic shock. CASE REPORT: A 43-year-old woman who had undergone RYGB surgery and who had multiple complications presented to the emergency department with agitation, confusion, and lethargy. The physical examination revealed an obtunded woman appearing much older than her reported age with significant peripheral edema. She was hypoxemic, hypotensive, and febrile. The initial laboratory analysis revealed a serum lactate level above the measurable limit, a normal thyroid-stimulating hormone, and elevated levels of troponin and brain natriuretic peptide. A transthoracic echocardiogram showed high-output heart failure. The patient's family later revealed that for the past year her diet had consisted almost exclusively of frozen blended lattes. High doses of thiamine and folate were started. Her shock, hyperlactatemia, and respiratory failure resolved by hospital day 3 and her encephalopathy resolved soon thereafter. Why Should an Emergency Physician be Aware of This?: Thiamine deficiency is a rare but reversible cause of shock, heart failure, and encephalopathy. Identifying patients who are at risk for severe nutritional deficiencies may aid in more rapid treatment with relatively benign medications with little downside, in this case high-dose vitamin B1, and ultimately improve patient-oriented outcomes such as mortality, morbidity, and hospital length of stay.

An Unusual Case of Neonatal High-Output Heart Failure: Infantile Hepatic Hemangioma.

BACKGROUND: Infantile hepatic hemangioma (IHH) is a rare but life-threatening disorder that must be considered in the newborn presenting with high-output heart failure (HF). IHH is a tumor comprised of large vascular beds, which require a significant increase in blood flow as the lesion grows. This, in turn, creates an undue burden on the cardiovascular system, leading to high-output HF and potentially, respiratory distress. Recent changes have been made in the classification of certain hepatic hemangiomas and their treatments. CASE REPORT: A 10-day-old girl presented to the Emergency Department with increased respiratory effort and an episode of apnea and cyanosis. A chest x-ray study was obtained and showed cardiomegaly and pulmonary edema concerning for HF. The patient was promptly admitted to the pediatric intensive care unit, where advanced imaging was obtained revealing findings consistent with IHH. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: HF in an infant is a critical condition often requiring prompt intervention and rapid diagnosis of the correct etiology to save a life. IHH is an example of an extrathoracic etiology of pediatric HF that has undergone recent changes in terminology and diagnosis. Increased awareness among emergency physicians of this disease process and its treatments can lead to expeditious diagnosis and treatment of this potentially life-threatening illness.

Iatrogenic Decompensated Heart Failure.

PURPOSE OF REVIEW: To provide an overview of the potential iatrogenic causes of acute decompensated heart failure (AHF) and an evidence-based management strategy to address this. RECENT FINDINGS: As the heart failure (HF) population continues to age and become burdened with greater comorbidities and polypharmacy, patients become more susceptible to the iatrogenic precipitants of HF. The following clinical scenarios are familiar to clinicians, but the sequelae to AHF are often unanticipated: HF medications withdrawn during an intercurrent illness and not restarted, cardiotoxic therapy prescribed for cancer without timely and regular monitoring of left ventricular function, excessive intravenous fluids administered for sepsis or postoperatively, a blood transfusion volume not adjusted for body weight, iatrogenic anaemia that goes unnoticed or an inappropriate type of pacemaker implanted in a patient with underlying left ventricular systolic dysfunction. Iatrogenic decompensated HF is a phenomenon that is infrequently documented in the literature but increasingly confronted by clinicians of all specialties. It is associated with a high mortality and morbidity rate. By having greater awareness of these triggers, iatrogenic AHF should be one that is prevented rather than managed when it occurs.

Conditional knockout of activin like kinase-1 (ALK-1) leads to heart failure without maladaptive remodeling.

Activin like kinase-1 (AlK-1) mediates signaling via the transforming growth factor beta (TGFß) family of ligands. AlK-1 activity promotes endothelial proliferation and migration. Reduced AlK-1 activity is associated with arteriovenous malformations. No studies have examined the effect of global AlK-1 deletion on indices of cardiac remodeling. We hypothesized that reduced levels of AlK-1 promote maladaptive cardiac remodeling. To test this hypothesis, we employed AlK-1 conditional knockout mice (cKO) harboring the ROSA26-CreER knock-in allele, whereby a single dose of intraperitoneal tamoxifen triggered ubiquitous Cre recombinase-mediated excision of floxed AlK-1 alleles. Tamoxifen treated wild-type (WT-TAM; n = 5) and vehicle treated AlK-1-cKO mice (cKO-CON; n = 5) served as controls for tamoxifen treated AlK-1-cKO mice (cKO-TAM; n = 15). AlK-1 cKO-TAM mice demonstrated reduced 14-day survival compared to cKO-CON controls (13 vs 100%, respectively, p < 0.01). Seven days after treatment, cKO-TAM mice exhibited reduced left ventricular (LV) fractional shortening, progressive LV dilation, and gastrointestinal bleeding. After 14 days total body mass was reduced, but LV and lung mass increased in cKO-TAM not cKO-CON mice. Peak LV systolic pressure, contractility, and arterial elastance were reduced, but LV end-diastolic pressure and stroke volume were increased in cKO-TAM, not cKO-CON mice. LV AlK-1 mRNA levels were reduced in cKO-TAM, not cKO-CON mice. LV levels of other TGFß-family ligands and receptors (AlK5, TBRII, BMPRII, Endoglin, BMP7, BMP9, and TGFß1) were unchanged between groups. Cardiomyocyte area and LV levels of BNP were increased in cKO-TAM mice, but LV levels of ß-MHC and SERCA were unchanged. No increase in markers of cardiac fibrosis, Type I collagen, CTGF, or PAI-1, were observed between groups. No differences were observed for any variable studied between cKO-CON and WT-TAM mice. Global deletion of AlK-1 is associated with the development of high output heart failure without maladaptive remodeling. Future studies exploring the functional role of AlK-1 in cardiac remodeling independent of systemic AVMs are required.

Hereditary haemorrhagic telangiectasia: to transplant or not to transplant - is there a right time for liver transplantation?

BACKGROUND & AIMS: Hereditary haemorrhagic telangiectasia is characterized by arterio-venous malformations (AVM). It frequently involves the liver without clinical symptoms, but may lead to biliary ischaemia, portal hypertension, or fatal high-output heart failure. The indication of liver transplantation is controversial. METHODS: Herein, we report the case of a 65-year-old female patient with a 'double Osler syndrome' consisting of hereditary haemorrhagic telangiectasia (HHT) and type I hereditary angioedema diagnosed at the age of 25 and 22 years respectively. RESULTS: Hereditary angioedema was treated with danazol for several decades until multiple hypoechogenic liver masses were detected. Albeit danazol treatment was replaced by C1 esterase inhibitor infusions, hepatocellular carcinoma was diagnosed at the age of 64 and the patient was listed for liver transplantation. HHT was marked by recurrent epistaxis until the age of 63 when severe intestinal bleeding occurred. At the age of 65, severe dyspnoea (NYHA class IV) developed and rapidly progressive high-output cardiac failure was diagnosed. Despite argon plasma coagulation to control bleeding from intestinal angiodysplasia, and treatment with bevacizumab to inhibit angiogenesis, the patient died from severe gastrointestinal bleeding associated with cardiogenic shock at the age of 66 before being transplanted. CONCLUSION: The indication to list this patient for liver transplantation was debated several times before the diagnosis of hepatocellular carcinoma because of good general condition and low MELD score. Precise guidelines for screening and management of patients with hepatic HHT need to be better defined.

Identifying the presence of clinically significant hepatic involvement in hereditary haemorrhagic telangiectasia using a simple clinical scoring index.

BACKGROUND & AIMS: Though hepatic involvement is common in patients with hereditary haemorrhagic telangiectasia (HHT), symptomatic liver disease is rare but potentially fatal without liver transplantation. Factors associated with clinically significant liver disease in patients with HHT are unknown. METHODS: In this prospective cohort study, we included consecutive patients from 2001 to 2011 with definite HHT, who underwent systematic protocol screening including contrast-enhanced hepatic CT and/or abdominal ultrasound. Using a multivariable logistic regression model, we developed a simple clinical scoring index to identify the presence of symptomatic liver disease (cardiac failure, portal hypertension, or biliary disease) or 'at-risk' liver disease (asymptomatic patients, with hepatic bruit, abnormal liver biochemistry, or elevated cardiac index). RESULTS: Of 316 patients with definite HHT, 171 patients (54.1%; age 53.4 ± 15.2 y, 101 females) had hepatic involvement on imaging. Twenty-nine patients had symptomatic liver disease (22 patients with high-output heart failure); 45 patients were 'at-risk' for liver disease. Using multivariable logistic regression analysis, we derived a score using age, gender, hemoglobin and alkaline phosphatase at presentation which could accurately distinguish patients with clinically significant liver involvement from patients with no or incidental liver lesions (c-statistic=0.80). A score <3 indicated low risk (<5%) and score >6 indicated high risk (>80%) of harboring clinically significant liver disease in HHT. CONCLUSIONS: A simple scoring system can distinguish patients at low, moderate, and high risk of harboring clinically significant liver disease. With validation, this score may be used to identify patients for individualized screening and enrollment in clinical trials.

High-Output Heart Failure in Multiple Myeloma: Novel Application of Tc-99m MAA to Identify Intramedullary Shunting.

We introduce the innovative use of technetium-99m-labeled macroaggregated albumin to diagnose high-output heart failure in a patient with multiple myeloma with persistent congestion symptoms. Symptom resolution occurred with lenalidomide and steroids. This marks the first clinical use of technetium-99m-labeled macroaggregated albumin for clarifying high-output heart failure etiology.

Spontaneous Iliac Arteriovenous Fistula Leading to High-Output Heart Failure and Cardiac Arrest.

We report a case of a 70-year-old male who complained to family members of the sudden onset of groin pain. He then collapsed, and emergency medical services were called. The patient arrived at the ED with a return of spontaneous circulation after cardiac arrest. The patient was diagnosed with a spontaneous iliac arteriovenous (AV) fistula secondary to aneurysmal rupture. This is a rare but potentially life-threatening condition that can result in high-output heart failure and, as described here, cardiac arrest. The differential diagnosis of groin pain is vast, but in the setting of cardiac arrest, vascular causes must be considered. Treatment is most often operative intervention, as was the case with the patient presented. It is predictable that as the population ages and invasive vascular surgeries become more common, the incidence of iliac AV fistulas will increase, resulting in more presentations of high-output heart failure or cardiac arrest in the emergency department.

Untreated Graves' Disease Complicated by Thyroid Storm and High-Output Cardiac Failure: A Case Report.

Thyroid storm is a rare yet critical complication of uncontrolled thyrotoxicosis, posing significant challenges in clinical management. We present the case of a 65-year-old African-American female with a medical history significant for untreated Graves' disease, hypertension, and diverticulosis, who presented with escalating abdominal pain, accompanied by nausea, vomiting, diarrhea, and chest discomfort. Upon admission, she exhibited atrial fibrillation with rapid ventricular response (RVR) and newly diagnosed high-output cardiac failure. Diagnosis of thyroid storm was confirmed through comprehensive laboratory assessments and clinical evaluation. Treatment with beta-blockers, anti-thyroid medications, and corticosteroids facilitated stabilization of her condition. This case report highlights the importance of early identification and intervention in thyroid storm to avert potential morbidity and mortality.

High-output heart failure due to a giant left circumflex coronary aneurysm with a left atrial fistula and atrial septal defect: a case report.

Background: A coronary artery aneurysm is a rare cardiac anomaly that may be incidentally detected on echocardiography. When associated with a coronary cameral fistula, an aneurysm can become symptomatic. We present a unique case of a giant left circumflex coronary aneurysm with a fistula to the left atrium and a large atrial septal defect causing acute heart failure in a young woman during the peripartum period. Case summary: A 32 year-old woman who presented with hypoxia after the delivery of her fourth child was found to have heart failure with severe mitral regurgitation and multiple abnormal intracardiac shunts. Echocardiography showed a large circular structure with Doppler color flow into the left atrium and between the atria. Cardiac computed tomography showed multiple dilated coronary arteries including a left circumflex coronary artery aneurysm measuring >10 cm in diameter with fistulous communication to the left atrium and a large atrial septal defect. A right heart catheterization was performed, and the patient was diagnosed with high-output heart failure. Surgical closure of the coronary cameral fistula was deferred due to the risk of worsening pressure in the coronary aneurysm, and the patient was referred for cardiac transplantation. Discussion: This case illustrates severe heart failure as a complication of a giant coronary artery aneurysm with fistulization to the left atrium and subsequent shunting through a large atrial defect. Echocardiography allows for the detection of a coronary aneurysm and shunting, and cardiac computed tomography provides detailed visualization of a coronary cameral fistula.

Descriptive spectrum of thiamine deficiency in pregnancy: A potentially preventable condition.

OBJECTIVE: Pregnancy, a nutritionally demanding situation in terms of macro- and micronutrient supply owing to heightened maternal, placental, and fetal needs, significantly affects thiamine reserves. Thiamine deficiency during pregnancy and the postpartum period, presenting with varied manifestations and outcomes, is a relatively common condition in our population. The study aimed to understand the various manifestations and outcomes of acute thiamine deficiency in pregnant and postpartum women, emphasizing the significance of early recognition and thiamine therapy to prevent serious complications during pregnancy and after childbirth. METHODS: This prospective study conducted in a tertiary care center in North India enrolled consecutive pregnant and postpartum women presenting with clinical features consistent with thiamine deficiency disorders, such as thiamine deficiency-related neuropathy, high-output heart failure, heart failure with reduced ejection fraction, Wernicke's encephalopathy, gastric beriberi, and thiamine-responsive acute pulmonary hypertension. In addition to capturing medical history including drug intake, dietary consumption, and comorbidities, women underwent brief relevant clinical examinations and laboratory assessments, including whole-blood thiamine levels. Response to intravenous thiamine supplementation was also monitored. RESULTS: Data of 31 women (12 pregnant, 19 postpartum) with a diagnosis of acute thiamine deficiency and a mean age of 28.88 ± 2.69 years were analyzed. The mean thiamine level was 1.28 ± 0.44 µg/dL with mean blood lactate of 3.46 ± 3.33. The most common presentation was gastric beriberi (n = 10), followed by paraparesis (n = 6), high-output heart failure (n = 6), acute pulmonary hypertension, heart failure with reduced ejection fraction (n = 3 each), and an acute confusional state (n = 2). All patients responded to thiamine challenge. CONCLUSION: In the context of borderline thiamine status, particularly in our population with endemic thiamine deficiency and heightened demand for thiamine during pregnancy and the peripartum period, the deficiency can have varied and serious manifestations of dry and wet beriberi. Early recognition of the clinical features and thiamine therapy can be life-saving. There is a need for validated clinical criteria owing to the non-availability of thiamine testing in resource-limited settings.

High Output Heart Failure Due to Iatrogenic Iliac Arteriovenous Fistula: Complication of Spine Surgery.

This case shows the risk of severe cardiovascular complications following lumbar spine surgery, with progressive high output heart failure caused by an iatrogenic iliac arteriovenous fistula. Careful history taking and thorough physical examination are essential in guiding the diagnosis. Endovascular repair can provide excellent short- and long-term outcomes.

Propranolol Monotherapy in Multifocal/Diffuse Infantile Hepatic Hemangiomas in Indian Children: A Case Series.

Introduction: Infantile hepatic hemangioma (IHH) is the most common benign liver tumor in children, and multifocal and diffuse tumors often become life-threatening, necessitating therapy. Propranolol is now considered the first choice of therapy with ample data in Caucasian children. We present a series of nine Indian children with multifocal (n = 5) and diffuse (n = 4) IHH treated with propranolol monotherapy. Methods: This was a retrospective clinical data-based single-center study. Propranolol was used at a median dose of 3.2 mg/kg/day (range 3-3.3 mg/kg/day) for a median duration of 12 months (range 6-32 months). Results: The presentations of IHH (either in isolation or combination) were hypothyroidism in six patients (diagnosed by elevated serum TSH levels), heart failure in three (diagnosed based on clinical and echocardiographic features), and imaging evidence of macrovascular shunting in two patients. A good response to propranolol monotherapy (with a median dose of 3.2 mg/kg/day for a median duration of 12 months) was observed in eight patients, with a poor response in one. One patient experienced recurrence but responded adequately to propranolol retreatment. Conclusions: Our data reiterate the excellent response (88.9% responded) and safety profile with propranolol monotherapy in complicated IHH and strengthen the data in Asian (Indian) children. It includes the maximum proportion of complicated IHH treated with propranolol in East and South Asia, and the largest series from India.

Heart failure with preserved ejection fraction is the most frequent but commonly overlooked phenotype in patients on chronic hemodialysis.

Introduction: Heart failure (HF) is a serious complication of end-stage kidney disease (ESKD). However, most data come from retrospective studies that included patients on chronic hemodialysis at the time of its initiation. These patients are frequently overhydrated, which significantly influences the echocardiogram findings. The primary aim of this study was to analyze the prevalence of heart failure and its phenotypes. The secondary aims were (1) to describe the potential of N-terminal pro-brain natriuretic peptide (NTproBNP) for HF diagnosis in ESKD patients on hemodialysis, (2) to analyze the frequency of abnormal left ventricular geometry, and (3) to describe the differences between various HF phenotypes in this population. Methods: We included all patients on chronic hemodialysis for at least 3 months from five hemodialysis units who were willing to participate, had no living kidney transplant donor, and had a life expectancy longer than 6 months at the time of inclusion. Detailed echocardiography together with hemodynamic calculations, dialysis arteriovenous fistula flow volume calculation, and basic lab analysis were performed in conditions of clinical stability. Excess of severe overhydration was excluded by clinical examination and by employing bioimpedance. Results: A total of 214 patients aged 66.4 ± 14.6 years were included. HF was diagnosed in 57% of them. Among patients with HF, HF with preserved ejection fraction (HFpEF) was, by far, the most common phenotype and occurred in 35%, while HF with reduced ejection fraction (HFrEF) occurred only in 7%, HF with mildly reduced ejection fraction (HFmrEF) in 7%, and high-output HF in 9%. Patients with HFpEF differed from patients with no HF significantly in the following: they were older (62 ± 14 vs. 70 ± 14, p = 0.002) and had a higher left ventricular mass index [96(36) vs. 108(45), p = 0.015], higher left atrial index [33(12) vs. 44(16), p < 0.0001], and higher estimated central venous pressure [5(4) vs. 6(8), p = 0.004] and pulmonary artery systolic pressure [31(9) vs. 40(23), p = 0.006] but slightly lower tricuspid annular plane systolic excursion (TAPSE): 22 ± 5 vs. 24 ± 5, p = 0.04. NTproBNP had low sensitivity and specificity for diagnosing HF or HFpEF: with the use of the cutoff value of 8,296 ng/L, the sensitivity of HF diagnosis was only 52% while the specificity was 79%. However, NTproBNP levels were significantly related to echocardiographic variables, most significantly to the indexed left atrial volume (R = 0.56, p < 10-5) and to the estimated systolic pulmonary arterial pressure (R = 0.50, p < 10-5). Conclusions: HFpEF was by far the most common heart failure phenotype in patients on chronic hemodialysis and was followed by high-output HF. Patients suffering from HFpEF were older and had not only typical echocardiographic changes but also higher hydration that mirrored increased filling pressures of both ventricles than in those of patients without HF.
