Cobalt protoporphyrin promotes heme oxygenase 1 expression and ameliorates cardiac dysfunction in long-term fasting mice. Int J Cardiol 2024; 404:131972. [PMID: 38490272 DOI: 10.1016/j.ijcard.2024.131972] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/26/2023] [Revised: 01/15/2024] [Accepted: 03/12/2024] [Indexed: 03/17/2024]
Abstract
BACKGROUND The association between malnutrition and cardiac dysfunction has been reported. Heme oxygenase (HO)-1 played protective roles in the animals functioning as a myocardial infarction, heart failure, or cardiomyopathy model. We hypothesized that the administration of HO-1 inducer, cobalt protoporphyrin (CoPP) reduces oxidative stress and ameliorates cardiac systolic dysfunction in long-term fasting mice. METHODS C57BL/6 J mice were classified into three groups: fed mice (fed group), 48-h fasting mice with a single intraperitoneal injection of the corresponding vehicle (fasting group), and 48-h fasting mice with a single intraperitoneal injection of 5 mg/kg CoPP (CoPP group). RESULTS The fasting group showed a significant increase in heme and 4-hydroxy-2-nonenal (4HNE) protein in the heart tissue, and reduced left ventricular ejection fraction (LVEF) when compared with the fed group. The CoPP group showed significantly increased protein levels of nuclear factor-erythroid 2-related factor 2 and HO-1, and increased mRNA expression levels of HO-1, peroxisome proliferator-activated receptor gamma coactivator 1-alpha, forkhead box protein O1, sirtuin-1, cyclooxygenase 2, and superoxide dismutase 2, and reduced levels of heme and 4HNE protein when compared with the fasting group. LVEF were significantly higher in the CoPP group than in the fasting group. CONCLUSIONS Administration of CoPP reduced heme accumulation and oxidative stress, and ameliorated cardiac systolic dysfunction in long-term fasting mice. This study suggests that heme accumulation may be associated with impaired cardiac function induced by long-term fasting and that HO-1 may be a key factor or therapeutic target.

Cardiac involvement and its clinical significance in patients with anorexia nervosa. Eur J Pediatr 2024; 183:95-102. [PMID: 37934282 DOI: 10.1007/s00431-023-05305-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/03/2023] [Revised: 10/20/2023] [Accepted: 10/22/2023] [Indexed: 11/08/2023]
Abstract
Cardiac complications are a major concern in patients with anorexia nervosa (AN) which contribute to morbidity and mortality. However, limited information exists regarding risk factors for the development of these complications. Our objective was to investigate the prevalence and associated risk factors of cardiac involvement among children and adolescents with AN admitted to a tertiary pediatric hospital. We collected demographic, clinical, and laboratory data from individuals with AN hospitalized between 2011 and 2020 in Schneider Children's Medical Center in Israel. Diagnosis was based on established criteria (DSM-5). Patients with other co-morbidities were excluded. Cardiac investigations included electrocardiograms (ECG) and echocardiograms. We conducted correlation tests between cardiac findings and clinical and laboratory indicators. A total of 403 AN patients (81.4% were females) with a median age of 15 ± 2 years were included in the study. Sinus bradycardia was the most common abnormality, observed in 155 (38%) participants. Echocardiogram was performed in 170 (42.2%) patients, of whom 37 (22%) demonstrated mild cardiac aberrations. Among those aberrations, 94.6% could be attributed to the current metabolic state, including pericardial effusion (15.3%) and valve dysfunction (8.8%). Systolic or diastolic cardiac dysfunction, tachyarrhythmias, or conduction disorders were not observed. Patients with new echocardiographic aberration had significantly lower body mass index (BMI) at admission, and the prevalence of amenorrhea and hypotension was higher in this group. CONCLUSIONS The prevalence of cardiac involvement, except for sinus bradycardia, was notably low in our cohort. The presence of cardiac aberrations is correlated with several clinical variables: lower body mass index (BMI) and the presence of amenorrhea and hypotension at admission. Patients presenting with these variables may be at high risk for cardiac findings per echocardiography. Dividing the patients into high and low risk groups may enable targeted evaluation, while avoiding unnecessary cardiac investigations in low-risk patients. WHAT IS KNOWN • Cardiac involvement in anorexia nervosa (AN) patients is a major concern, which contributes to morbidity and mortality. • It is unknown which patients are prone to develop this complication. WHAT IS NEW • Cardiac complications in our cohort are less frequent compared to previous studies, and it is correlated with lower body mass index (BMI) at admission, and the prevalence of amenorrhea and hypotension.

Impact of BMI z-score on left ventricular mechanics in adolescent girls. Front Pediatr 2023; 11:1165851. [PMID: 37565247 PMCID: PMC10410149 DOI: 10.3389/fped.2023.1165851] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/14/2023] [Accepted: 07/12/2023] [Indexed: 08/12/2023] Open
Abstract
Background Adolescent weight disorders ranging from anorexia nervosa (AN) to obesity (OB) can impact the heart by causing opposite alterations in its morphology, suggesting a direct impact of body mass index (BMI) on the heart. Cardiac function is relatively preserved as assessed by standard echocardiography. However, few studies have used 2D speckle-tracking echocardiography (2D-STE), which can detect subtle alterations of left ventricular (LV) function by evaluating deformations. This study aimed to assess the link between the BMI z-score of adolescent girls and myocardial function. Methods Ninety-one adolescent girls comprising 26 AN patients (age 14.6 ± 1.9 years), 28 OB patients (age 13.2 ± 1.4 years), and 37 controls (age 14.0 ± 2.0 years) underwent 2D-STE to assess LV morphology and myocardial global and regional deformations. Results The BMI z-score of our population ranged from -4.6 to 5.2. LV morphological remodeling was significantly and positively correlated with the BMI z-score (R2 = 0.456, p < 0.0001 for LV mass). Global longitudinal strain (LS) and regional LS recorded at the mid and apical levels were significantly correlated with the BMI z-score (R2 = 0.196, p = 0.0001 and R2 = 0.274, p < 0.0001, respectively, for apical and medial LS). Circumferential strains and twisting mechanics were not correlated with the BMI z-score. Fibrinogen and systolic blood pressure were the main variables explaining the alteration of LS. Conclusion We observed that the BMI z-score had an impact on LV mechanics, especially on medial and apical LS. Neither circumferential nor twisting mechanics were altered by the BMI z-score in adolescent girls.

Early echocardiographic evaluation of children admitted to the emergency department for anorexia nervosa during the COVID-19 pandemic. Eat Weight Disord 2022; 27:3409-3417. [PMID: 36053460 PMCID: PMC9438386 DOI: 10.1007/s40519-022-01474-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/05/2022] [Accepted: 08/21/2022] [Indexed: 01/04/2023] Open
Abstract
PURPOSE Anorexia nervosa (AN) is the most frequent eating disorder (ED), whose cardiac complications may have life-threatening consequences for both the physical and psychological health of affected children. In this study, we reported and analysed the echocardiographic anomalies found in pediatric patients diagnosed with AN. METHODS We reported the demographic and clinical characteristics of children aged 8 to 18 years, who were diagnosed with AN and underwent a complete cardiological evaluation at the Emergency Department of the Bambino Gesù Children's Hospital, IRCCS, Rome between the 1st January 2021 and the 30th June 2021. Furthermore, we compared the patients according to the presence of pericardial effusion and a BMI (body mass index) cut-off 14.5 kg/m2. RESULTS Forty-nine patients were included in the study. The mean age was 15.1 years. Most patients were female (89.8%). The mean length of hospitalization was 18 days. The mean BMI at admission was 14.8 kg/m2, with a median weight loss of 9 kg in the last year. Eleven patients (22.4%) presented with cardiovascular signs or symptoms at admission. Most patients had pericardial effusion on heart ultrasound, with a mean thickness of 6 mm (SD ± 4). The LV (left ventricle) thickness over age was significantly higher in patients with pericardial effusion, with a Z score of -2.0 vs -1.4 (p = 0.014). The administration of psychiatric drugs was significantly more frequent in patients with a lower BMI (37.5% vs 12%, p = 0.038). CONCLUSION Our study suggests that a non-urgent baseline echocardiographic evaluation with focus on left-ventricular wall thickness and mass in children with anorexia nervosa is advisable. LEVEL III Evidence obtained from cohort or case-control analytic studies.

Cardiac Complications Associated with Eating Disorders in Children: A Multicenter Retrospective Study. Pediatr Gastroenterol Hepatol Nutr 2022; 25:432-440. [PMID: 36148287 PMCID: PMC9482826 DOI: 10.5223/pghn.2022.25.5.432] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/21/2022] [Revised: 05/30/2022] [Accepted: 07/20/2022] [Indexed: 11/20/2022] Open
Abstract
PURPOSE Eating disorders often result in somatic complications, including cardiac abnormalities. Cardiac abnormalities may involve any part of the heart, including the cardiac conduction system, and can lead to sudden cardiac death. The current study aimed to evaluate the incidence of cardiac complications in pediatric patients with eating disorders and their associated factors. METHODS We retrospectively analyzed patients aged 10-18 years who were diagnosed with DSM-V (Diagnostic and Statistical Manual of Mental Disorder-V) eating disorders and underwent electrocardiography (ECG) and/or echocardiography between January 2015 and May 2020. RESULTS In total, 127 patients were included, of whom 113 (89.0%) were female. The median body mass index (BMI) was 15.05±3.69 kg/m2. Overall, 74 patients (58.3%) had ECG abnormalities, with sinus bradycardia being the most common abnormality (91.9%). Patients with ECG abnormalities had significantly lower BMI (14.35±2.78 kg/m2 vs. 16.06± 4.55 kg/m2, p<0.001) than patients without ECG abnormalities, as well as lower phosphorus and higher cholesterol levels. Among the 46 patients who underwent echocardiographic evaluation, 23 (50.0%) had echocardiographic abnormalities, with pericardial effusion being the most common (60.9%). The median left ventricular mass (LVM) and ejection fraction were 67.97±21.25 g and 66.91±28.76%, respectively. LVM and BMI showed a positive correlation (r=0.604, p<0.001). After weight gain, the amount of pericardial effusion was reduced in 3 patients, and 30 patients presented with normal ECG findings. CONCLUSION Cardiac abnormalities are relatively frequent in patients with eating disorders. Physicians should focus on this somatic complication and careful monitoring is required.

Abstract
Anorexia nervosa (AN) is a psychiatric disorder that may lead to cardiac complications. The objective of this study was to evaluate global and regional longitudinal strain changes in patients affected by AN as an early marker of myocardial damage. We prospectively enrolled 48 consecutive patients with AN and 44 age-matched and gender-matched healthy controls. In all subjects, we performed echocardiography, including global longitudinal strain (GLS) measurement. A subset of 33 patients with AN had further echocardiographic examinations during the follow-up. Compared with healthy controls, patients with AN had a greater prevalence of pericardial effusion (9 of 48 vs 0 of 44, p = 0.003), a smaller left ventricular mass (63 ± 15 vs 99 ± 30 g, p < 0.001), a lower absolute value of GLS (-18.9 ± 2.8 vs -20.2 ± 1.8%, p = 0.010) and of basal LS (-15.4 ± 6.0 vs -19.4 ± 2.6%, p < 0.001). The bull's eye mapping showed a plot pattern with blue basal areas in 18 of 48 patients with AN versus 1 of 44 controls (p < 0.001). During the follow-up, of 13 patients with blue areas in the first bull's eye mapping, 11 recovered completely, and of 20 patients with a red bull's eye at the first examination, none presented blue areas at the second one. In conclusion, GLS is significantly altered in patients with AN, and a basal blue pattern on bull's eye mapping identifies more severe cases. These changes seem to be reversible.

Echocardiographic changes in anorexia nervosa: a pathophysiological adaptation or a disease? Intern Emerg Med 2022; 17:777-787. [PMID: 34677790 DOI: 10.1007/s11739-021-02871-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/21/2021] [Accepted: 10/12/2021] [Indexed: 11/25/2022]
Abstract
Anorexia Nervosa is one of the most common form of eating disorders. Cardiac involvement occurs in approximately 80% of patients. Few reports focused on the association between body weight fluctuations and echocardiographic abnormalities, considering linear measurements. We describe echocardiographic and clinical features among male and female patients with anorexia nervosa and the effect of weight gain on these parameters. We performed a single center, retrospective study of patients followed at a dedicated multidisciplinary Unit. The study population consisted of 81 patients, mean age 25 ± 11 years, 94% female. Median body mass index was 14.4 kg/m2 (25th-75th percentile 12.7-15.6 kg/m2). Patients with body mass index below the median value had more often pericardial effusion, smaller left ventricular mass and left ventricular end-diastolic volume and thinner interventricular septum. However, when indexed to body surface area, left ventricular mass and volumes were within the normal range in 90% of population. Patients with pericardial effusion showed mitral valve abnormalities and lower values of white blood cells and platelets, although within normal limits. Presence of pericardial effusion was not related to inflammatory parameters or low plasma protein levels. In 39 patients who displayed weight gain during a median follow-up of 189 days (25th-75th percentile 47-471), increased left ventricular mass, interventricular septum thickness, white blood cells and platelet count and decreased pericardial effusion were observed. Patients with anorexia nervosa have a specific echocardiographic pattern which seems to be proportional to the body size, suggesting a pathophysiological adaptation to the lack of substrates.

Cardiac Remodeling and Its Determinants in Anorexia Nervosa Adolescents: Impact of Weight Recovery. CHILDREN (BASEL, SWITZERLAND) 2022; 9:children9040458. [PMID: 35455501 PMCID: PMC9031014 DOI: 10.3390/children9040458] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/07/2022] [Revised: 03/18/2022] [Accepted: 03/21/2022] [Indexed: 11/16/2022]
Abstract
Cardiovascular alterations in anorexia nervosa (AN) adolescents include bradycardia and decreased systolic blood pressure and left ventricular mass. However, their determinants remain poorly understood. We assessed the associations between morphological and functional left ventricular (LV) remodeling, autonomic control by heart rate variability (HRV) analysis, thyroid hormones and brain natriuretic peptide (BNP) levels in AN female adolescents without or with weight recovery (WR). Fifty-nine female adolescents including 16 AN patients without WR (mean age 13.9 years (10−16)), 10 AN patients with WR (15.7 years (12−18)) and 33 controls (14.1 years (10−18)) underwent night heart rate (HR) recording to measure HRV (and especially SD1/SD2, the ratio between instantaneous (SD1) and long-term (SD2) standard deviation of R-R intervals, reflecting sympatho-vagal balance), speckle tracking echocardiography to assess LV global longitudinal strain (GLS) and blood test for dosage of tri-iodothyronine (T3) hormone and NT-proBNP. Compared to controls, AN patients without WR presented with lower HR (55 ± 7 vs. 68 ± 6 bpm; p < 0.001), parasympathetic hyperactivity, and higher GLS (−19.2 ± 1.8 vs. −16.9 ± 2.8%; p = 0.009). These alterations were partly abolished in AN patients with WR. In a multivariate regression analysis, T3 was the main factor explaining the variance of SD1/SD2, a sympatho-vagal balance marker. NT-proBNP levels were not correlated with cardiac alterations. AN patients had parasympathetic hyperactivity linked with their rate of T3, and a higher GLS. These alterations were partly restored in AN patients with WR.

Left Ventricular Strains and Myocardial Work in Adolescents With Anorexia Nervosa. Front Cardiovasc Med 2022; 9:798774.

Abstract
Background Anorexia nervosa (AN) is accompanied by bradycardia, low blood pressure (BP) and cardiac morphological remodeling. Systolic and diastolic functions are relatively preserved when assessed by standard ultrasound methods. However, novel advances based on speckle tracking echocardiography (STE), that could detect subtle and early alterations of left ventricular (LV) function, remained poorly used in AN patients. Objective The aim of this study was to assess the cardiac function of AN patients by evaluating LV myocardial strains, myocardial work (MW) and LV mechanical dispersion. We hypothesized that LV strains and global myocardial work would be decreased and LV twisting mechanisms enhanced to preserve the systolic function. Methods Fifty-nine adolescents including 26 women AN patients (14.6 ± 1.9 yrs. old) with a mean duration of AN of 19 ± 9 months and 33 controls (14.1 ± 2.0 yrs. old) underwent STE to assess LV morphology and myocardial regional strains. Results The global longitudinal strain (GLS) was higher in AN patients compared to controls (−18.8 ± 2.0 vs. −16.9 ± 2.8%, p = 0.006). The area under the pressure-strain loop, representing the global MW was not altered but was shifted to the left and downwards in AN patients, due to their lower BP and higher GLS. Intraventricular mechanical dispersion was similar in both groups. Circumferential strains, twisting/untwisting mechanics were preserved. Conclusion Our results strongly support that the cardiac morphological remodeling observed in our AN patients was associated with normal ventricular regional myocardial functions. Only GLS was higher in AN patients, but its clinical significance remains to be demonstrated.

Abstract
BACKGROUND Anorexia nervosa has a prevalence of 0.5-3% in adolescents, placing this population at increased risk of cardiac anomalies including arrhythmias, pericardial effusion, and myocardial dysfunction. Our objective is to describe cardiovascular anomalies observed by tissue Doppler imaging in patients with anorexia nervosa. METHODS We retrospectively reviewed electrocardiogram, Holter, and echocardiography findings in 28 patients diagnosed with anorexia nervosa. RESULTS Electrocardiogram was abnormal in 71% of patients with sinus bradycardia observed in 57%. Holter confirmed sinus bradycardia without significant pauses. Prolonged QTc, low voltage, and ectopic beats were each seen in 14% of patients. Wenckebach atrioventricular block was observed in one patient. Supraventricular or ventricular tachycardia was not observed. Echocardiography showed structurally normal heart in all patients. Pericardial effusion was seen in 7.1% of patients and left ventricular mass was decreased in 10.7%. Mean ejection fraction was 0.73 and mean fractional shortening was 38.4%. Tissue Doppler imaging revealed systolic or diastolic dysfunction in four patients with e', a', and s' velocities in the lateral and septal basal segments more than two standard deviations below the mean. Two patients had decreased left ventricular mass but no significant difference in disease duration from the group. Basal segment velocities below one standard deviation were also observed in an additional seven patients. CONCLUSION A trend for decreased tissue Doppler imaging velocities was seen in 25.0% of patients, while significant systolic and diastolic dysfunction was seen in 14.3% of patients, associated with a significant reduction in left ventricular mass and independent of disease duration.

Abstract
BACKGROUND High mortality rates have been reported in patients with anorexia nervosa, mainly due to cardiovascular alterations. The purpose of the present study was to assess cardiac structural and functional abnormalities some 20 years after initial treatment in a sample of adolescent-onset anorexia nervosa (A-AN) and to compare them with matched healthy controls (HC). METHODS A sample of 29 women diagnosed and treated for AN during adolescence (A-AN) were assessed more than 20 years later. A complete cardiac evaluation was carried out including an electrocardiogram (ECG) and a standard 2D echocardiography. Thirty matched HC were also assessed. RESULTS In the A-AN group, four subjects had a body mass index lower than 18.5 and met full DSM 5 criteria for AN at follow-up (Low-Weight group). They were compared with the rest of the sample (n = 25) who had normalized their weight (Normal-Weight group), though some still showed some eating disorder symptoms. Both groups were compared with the HC group. Subjects in the Low-Weight group presented statistically significant decreases in the left ventricular end-diastolic and left atrium dimensions and left ventricular mass in comparison with the Normal-Weight group and the HC. No other differences in cardiac parameters were found between groups. CONCLUSIONS Echocardiographic and ECG parameters of adults who had presented A-AN twenty years earlier and currently maintained normal weight were similar to those of HC who had never been treated or diagnosed with AN. Adult subjects with A-AN who still had low weight in the long term present certain cardiac abnormalities similar to those seen in short-lasting disease. More studies are needed to confirm these results in a larger sample.

Anorexia nervosa-related cardiopathy in children with physical instability: prevalence, echocardiographic characteristics and reversibility at mid-term follow-up. Eur J Pediatr 2021; 180:3379-3389. [PMID: 34050378 DOI: 10.1007/s00431-021-04130-y] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/07/2021] [Revised: 05/17/2021] [Accepted: 05/20/2021] [Indexed: 10/21/2022]
Abstract
Prompt detection of cardiovascular abnormalities in children with anorexia nervosa and physical instability requiring hospitalization is essential to identify patients at higher cardiovascular risk. We studied all anorexia nervosa children requiring admission at Paediatric Institute in the period 2015-2019. Anorexia nervosa cardiopathy at admission was defined by the presence of at least two of the following clinical findings: pericardial effusion, mitral regurgitation, bradycardia, mitral billowing, aortic regurgitation, altered LV morphology and ECG abnormalities. Echocardiographic data were compared with those registered at 3-8-month follow-up and with data from a healthy population. Thirty-eight anorexia nervosa children were examined. Prevalence of anorexia nervosa cardiopathy at admission was 63% (24 patients). Pericardial effusion, bradycardia and mitral regurgitation were present together in 26% of patients. Most cardiovascular changes recovered at follow-up. Anorexia nervosa cardiopathy was associated with significantly lower left ventricle end-diastolic diameters and mass, and higher E wave, E/A and E/e' ratios and left ventricle sphericity index values vs healthy population and vs anorexia nervosa children without cardiopathy (p<0.05). Left ventricle global longitudinal strain was significantly reduced only in anorexia nervosa cardiopathy patients but recovered, whereas end-diastolic diameters, E/A ratio and sphericity index values remained impaired.Conclusion: Among anorexia nervosa children requiring hospitalization, those presenting several cardiac findings together express an acute anorexia nervosa cardiopathy which is characterized by worse LV filling, geometry and subclinical myocardial deformation impairment. Despite treatment, in those patients, some alterations persist at mid-term follow-up. What is Known: • Cardiac and electrocardiographic changes are present in anorexia nervosa children at diagnosis or during stable disease, and most recover after body-weight treatment. • It is unknown if anorexia nervosa children with more severe cardiac impairment during hospitalization present higher cardiovascular-risk profile despite treatment. What is New: • In anorexia nervosa children needing hospitalization for physical reasons, prevalence of acute anorexia nervosa cardiopathy at admission is high, around 60%. • By advanced echocardiography, children with anorexia nervosa cardiopathy at admission have a worse cardiac filling, impaired cardiac geometry and systolic deformation that only partially recover at mid-term follow-up.

Abstract
BACKGROUND Anorexia nervosa affects most organ systems, with 80% suffering from cardiovascular complications. AIMS To define echocardiographic abnormalities in anorexia nervosa through systematic review and meta-analysis. METHOD Two reviewers independently assessed eligibility of publications from Medline, EMBASE and Cochrane Database of Systematic Reviews registries. Studies were included if anorexia nervosa was the primary eating disorder and the main clinical association in described cardiac abnormalities. Data was extracted in duplicate and quality-assessed with a modified Newcastle-Ottawa scale. For continuous outcomes we calculated mean and standardised mean difference (SMD), and corresponding 95% confidence interval. For dichotomous outcomes we calculated proportion and corresponding 95% confidence interval. For qualitative data we summarised the studies. RESULTS We identified 23 eligible studies totalling 960 patients, with a mean age of 17 years and mean body mass index of 15.2 kg/m2. Fourteen studies (469 participants) reported data suitable for meta-analysis. Cardiac abnormalities seen in anorexia nervosa compared with healthy controls were reduced left ventricular mass (SMD 1.82, 95% CI 1.32-2.31, P < 0.001), reduced cardiac output (SMD 1.92, 95% CI 1.38-2.45, P < 0.001), increased E/A ratio (SMD -1.10, 95% CI -1.67 to -0.54, P < 0.001), and increased incidence of pericardial effusions (25% of patients, P < 0.01, 95% CI 17-34%, I2 = 80%). Trends toward improvement were seen with weight restoration. CONCLUSIONS Patients with anorexia nervosa have structural and functional cardiac changes, identifiable with echocardiography. Further work should determine whether echocardiography can help stratify severity and guide safe patient location, management and effectiveness of nutritional rehabilitation.

How to diagnose heart failure with preserved ejection fraction: the HFA-PEFF diagnostic algorithm: a consensus recommendation from the Heart Failure Association (HFA) of the European Society of Cardiology (ESC). Eur Heart J 2020; 40:3297-3317. [PMID: 31504452 DOI: 10.1093/eurheartj/ehz641] [Citation(s) in RCA: 749] [Impact Index Per Article: 187.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/16/2018] [Revised: 10/30/2018] [Accepted: 08/26/2019] [Indexed: 02/07/2023] Open
Abstract
Making a firm diagnosis of chronic heart failure with preserved ejection fraction (HFpEF) remains a challenge. We recommend a new stepwise diagnostic process, the 'HFA-PEFF diagnostic algorithm'. Step 1 (P=Pre-test assessment) is typically performed in the ambulatory setting and includes assessment for HF symptoms and signs, typical clinical demographics (obesity, hypertension, diabetes mellitus, elderly, atrial fibrillation), and diagnostic laboratory tests, electrocardiogram, and echocardiography. In the absence of overt non-cardiac causes of breathlessness, HFpEF can be suspected if there is a normal left ventricular ejection fraction, no significant heart valve disease or cardiac ischaemia, and at least one typical risk factor. Elevated natriuretic peptides support, but normal levels do not exclude a diagnosis of HFpEF. The second step (E: Echocardiography and Natriuretic Peptide Score) requires comprehensive echocardiography and is typically performed by a cardiologist. Measures include mitral annular early diastolic velocity (e'), left ventricular (LV) filling pressure estimated using E/e', left atrial volume index, LV mass index, LV relative wall thickness, tricuspid regurgitation velocity, LV global longitudinal systolic strain, and serum natriuretic peptide levels. Major (2 points) and Minor (1 point) criteria were defined from these measures. A score ≥5 points implies definite HFpEF; ≤1 point makes HFpEF unlikely. An intermediate score (2-4 points) implies diagnostic uncertainty, in which case Step 3 (F1: Functional testing) is recommended with echocardiographic or invasive haemodynamic exercise stress tests. Step 4 (F2: Final aetiology) is recommended to establish a possible specific cause of HFpEF or alternative explanations. Further research is needed for a better classification of HFpEF.

Echocardiographic abnormalities in 124 severely malnourished adult anorexia nervosa patients: frequency and relationship with body composition and biological features. J Eat Disord 2020; 8:66. [PMID: 33292690 PMCID: PMC7661163 DOI: 10.1186/s40337-020-00343-y] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/16/2019] [Accepted: 10/21/2020] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Anorexia Nervosa (AN) is a complex psychiatric disorder that can lead to specific somatic complications. Heart abnormalities are frequently reported, while their frequency and associated factors in severely malnourished AN patients remain poorly defined. OBJECTIVES This study aimed to characterize echocardiographic abnormalities in severely malnourished AN patients and to assess associated clinical, biological and related body composition features. METHODS Between January 2013 and January 2015, all severely malnourished adult patients with AN (Mental Disorders, 4th Edn.-DSM IVr) were included in a monocentric study performed in in a highly specialized AN inpatient unit. Electrocardiogram (ECG) and echocardiography were used to assess both heart rhythm and function. All inpatients underwent a Doppler echocardiography procedure after undergoing combined blood volume adjustment, micronutrients deficiencies supplementation and electrolyte disorders correction. Right Ventricular (RV) and Left Ventricular (LV) systolic and diastolic functions were collected and compared to 29 healthy normal subjects in a control group. RESULTS One hundred and 24 patients (119 (96%) women, 5 (4%) men) with a mean age of 30.1 ± 11 years old and an average Body Mass Index (BMI) of 12 kg/m2 were included. Ninety patients (73%) had been diagnosed with AN Restrictive type (AN-R), 34 (27%) an AN Binge eating/Purging type (AN-BP). Eighteen patients (15%) disclosed an abnormal Left Ventricular Ejection Fraction (LVEF) (< 52% for male and < 54% for female). LVEF impairment was associated with AN-BP patients (p < 0.017) and hypertransaminasemia (AST and/or ALT ≥2 N) (p < 0.05). Left Ventricular mass (LV mass) and Left Ventricular End Diastolic Diameter (LVEDD) were significantly reduced in patients (p < 0.001, p < 0.001). Left and right ventricular tissue Doppler Imaging Velocities (TDI) peak were reduced in patients: Septal and Lateral LV Sm velocities peaks respectively 10 ± 2 cm/s (vs 14 ± 2 cm/s in controls, p < 0.001), 12 ± 3 cm/s (vs 16 ± 3 cm/s in controls, p < 0.001), basal RV Sm velocity peaks at 14 ± 3 cm/s (vs 19 ± 3 cm/s in controls, p < 0.001). Additionally, LV and RV diastolic velocity peaks were reduced: LV septal and lateral velocity peaks were respectively 13 ± 3 cm/s (vs 18 ± 2 cm/s p < 0.001), 12 ± 3 cm/s (vs 22 ± 4 cm/s, p < 0.001) and RV diastolic velocity peaks at 14 ± 3 cm/s (vs 21 ± 4 cm/s p < 0.001). LV diastolic velocity TDI peaks were significantly associated with hypertransaminasemia (p < 0.05) and tended to be associated with a low all body Fat-Free Mass Index (FFMI) (using Dual-energy X- ray Absorptiometry (DXA) (HOLOGICQDR 4500) (p = 0.056). Thirty-four patients (27%) had a pericardial effusion and were significantly associated with a decreased all body FFMI (p < 0.036). CONCLUSION Heart abnormalities are frequent in malnourished patients with AN, particularly in AN-BP type. Both liver enzymes and body composition abnormalities tended to be associated with heart dysfunction (non-significant association). Prospective studies are needed to better characterize and describe the evolution of cardiac abnormalities during the refeeding period and subsequent weight restoration.

Abstract
Anorexia nervosa, one of the more frequent and severe eating disorders, is a chronic psychiatric disease with potentially serious somatic consequences. This behavioral symptomatology leads to weight loss, undernutrition, and more or less severe-potentially life-threatening-somatic complications including respiratory, hepatic, digestive and cardiac features, electrolyte disturbances, endocrine and bone impairment, immunodepression, and related opportunistic infections. In this review, the authors report an overview of cardiac diseases in this disease.

Micronutrients Deficiencies in 374 Severely Malnourished Anorexia Nervosa Inpatients. Nutrients 2019; 11:nu11040792. [PMID: 30959831 PMCID: PMC6520973 DOI: 10.3390/nu11040792] [Citation(s) in RCA: 36] [Impact Index Per Article: 7.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2019] [Revised: 03/27/2019] [Accepted: 04/01/2019] [Indexed: 12/18/2022] Open
Abstract
Introduction: Anorexia nervosa (AN) is a complex psychiatric disorder, which can lead to specific somatic complications. Undernutrition is a major diagnostic criteria of AN which can be associated with several micronutrients deficiencies. Objectives: This study aimed to determinate the prevalence of micronutrients deficiencies and to compare the differences between the two subtypes of AN (restricting type (AN-R) and binge-eating/purging type (AN-BP)). Methods: We report a large retrospective, monocentric study of patients hospitalized in a highly specialized nutrition unit between January 2011 and August 2017 for severe malnutrition treatment in the context of anorexia nervosa. Results: Three hundred and seventy-four patients (360 (96%) women, 14 (4%) men), age: 31.3 ± 12.9 years, Body Mass Index (BMI): 12.5 ± 1.7 kg/m2 were included; 253 (68%) patients had AN-R subtype while, 121 (32%) had AN-BP. Zinc had the highest deficiency prevalence 64.3%, followed by vitamin D (54.2%), copper (37.1%), selenium (20.5%), vitamin B1 (15%), vitamin B12 (4.7%), and vitamin B9 (8.9%). Patients with AN-BP type had longer disease duration, were older, and had a lower left ventricular ejection fraction (LVEF) (p < 0.001, p = 0.029, p = 0.009), when compared with AN-R type, patients who instead, had significantly higher Alanine Aminotransferase (ALT) and Brain Natriuretic Peptide (BNP) levels (p < 0.001, p < 0.021). In the AN-BP subgroup, as compared to AN-R, lower selenium (p < 0.001) and vitamin B12 plasma concentration (p < 0.036) were observed, whereas lower copper plasma concentration was observed in patients with AN-R type (p < 0.022). No significant differences were observed for zinc, vitamin B9, vitamin D, and vitamin B1 concentrations between the two types of AN patients. Conclusion: Severely malnourished AN patients have many micronutrient deficiencies. Differences between AN subtypes are identified. Micronutrients status of AN patients should be monitored and supplemented to prevent deficiencies related complications and to improve nutritional status. Prospective studies are needed to explore the symptoms and consequences of each deficiency, which can aggravate the prognosis during recovery.

Anorexia nervosa and heart disease: a systematic review. Eat Weight Disord 2019; 24:199-207. [PMID: 30173377 DOI: 10.1007/s40519-018-0567-1] [Citation(s) in RCA: 51] [Impact Index Per Article: 10.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/20/2018] [Accepted: 08/17/2018] [Indexed: 01/12/2023] Open
Abstract
Anorexia nervosa (AN) is an eating disorder that most frequently afflicts females in adolescence. In these subjects, cardiovascular complications are the main cause of morbidity and mortality. Aim of this review is to analyze the hemodynamic, pro-arrhythmic and structural changes occurring during all phases of this illness, including re-feeding. A systematic literature search was performed on studies in the MEDLINE database, from its inception until September 2017, with PUBMED interface focusing on AN and cardiovascular disease. This review demonstrated that the most common cardiac abnormalities in AN are bradycardia and QT interval prolongation, which may occasionally degenerate into ventricular arrhythmias such as Torsades des Pointes or ventricular fibrillation. As these arrhythmias may be the substrate of sudden cardiac death (SCD), they require cardiac monitoring in hospital. In addition, reduced cardiac mass, with smaller volumes and decreased cardiac output, may be found. Furthermore, mitral prolapse and a mild pericardial effusion may occur, the latter due to protein deficiency and low levels of thyroid hormone. In anorectic patients, some cases of hypercholesterolemia may be present; however, conclusive evidence that AN is an atherogenic condition is still lacking, although a few cases of myocardial infarction have been reported. Finally, refeeding syndrome (RFS), which occurs during the first days of refeeding, may engender a critically increased risk of acute, life-threatening cardiac complications.

Echocardiographic Assessment of Ventricular Function During Exercise in Adolescent Female Patients With Anorexia Nervosa. J Am Soc Echocardiogr 2019; 32:394-403.e3. [PMID: 30638724 DOI: 10.1016/j.echo.2018.10.014] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/28/2017] [Indexed: 10/27/2022]
Abstract
BACKGROUND Patients with anorexia nervosa (AN) have altered physiologic responses to exercise. The aim of this study was to investigate exercise capacity and ventricular function during exercise in adolescent patients with AN. METHODS Sixty-six adolescent female patients with AN and 21 adolescent female control subjects who exercised to volitional fatigue on a semisupine ergometer, using an incremental step protocol of 20 W every 3 min, were retrospectively studied. Heart rate, blood pressure, and echocardiographic Doppler indices were measured at rest and during each stage of exercise. Fractional shortening, rate-corrected mean velocity of circumferential fiber shortening, stress at peak systole, cardiac output, and cardiac index were calculated. Minute ventilation, oxygen consumption, carbon dioxide production, and respiratory exchange ratio were measured using open-circuit spirometry. RESULTS Patients with AN had significantly lower body mass index (16.7 vs 19.7 kg/m2, P < .001), total work (1,126 vs 1,914 J/kg, P < .001), and test duration (13.8 vs 20.8 min, P < .001) compared with control subjects. Peak minute ventilation, oxygen consumption, and carbon dioxide production were significantly decreased in patients with AN. Heart rate, systolic blood pressure, cardiac index, fractional shortening, and rate-corrected mean velocity of circumferential fiber shortening demonstrated similar patterns of increase with progressive exercise between groups but were decreased at peak exercise in patients with AN. Body mass index percentile, age, peak oxygen consumption, and peak cardiac output were independently associated with exercise duration. CONCLUSIONS Adolescent patients with AN have reduced exercise capacity and peak cardiovascular indices compared with control subjects but normal patterns of cardiovascular response during progressive exercise. Systolic ventricular function is maintained during exercise in adolescents with AN.

Excessive physical activity in young girls with restrictive-type anorexia nervosa: its role on cardiac structure and performance. Eat Weight Disord 2018; 23:653-663. [PMID: 29058271 DOI: 10.1007/s40519-017-0447-0] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/14/2017] [Accepted: 09/25/2017] [Indexed: 01/20/2023] Open
Abstract
PURPOSE The aim of this study was to investigate the influence of hyperactivity on left ventricular mass (LVM) in Anorexia Nervosa restricting-type (AN-R) and the correlation between LVM and auxologic parameters/circulating hormones. METHODS Echocardiography was performed in 44 AN-R girls, subgrouped in 24 hyperactive (ANH+) and 20 non-hyperactive (ANH-), and in 20 controls (HC). LVM indexed to Body Surface Area (LVMi) and LVM indexed to height (LVMh) were calculated. RESULTS LVMi and LVMh were significantly lower in the AN-R subjects compared to HC. Moreover, both LVMi and LVMh were higher in the ANH+ than in the ANH-. In the HC, LVMi was higher when compared to the ANH- subjects than to the ANH+. Stepwise analysis revealed that in the ANH+ group, fT4 was the only independent predictor of LVMh, while in the ANH- group, height was the only independent predictors of LVMi. CONCLUSIONS Despite its negative influence on disease severity and outcome, hyperactivity from the standpoint of cardiac function makes the LVM of AN-R young girls more similar to HC. LEVEL OF EVIDENCE Level III, case-control study.

Doppler Echocardiography Assessment of Aortic Stiffness in Female Adolescents with Anorexia Nervosa. J Am Soc Echocardiogr 2018; 31:784-790. [PMID: 29559196 DOI: 10.1016/j.echo.2018.01.003] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/14/2015] [Indexed: 01/08/2023]
Abstract
BACKGROUND Anorexia nervosa (AN) is associated with abnormalities in biomarkers of cardiovascular risk. Arterial stiffness, as measured by pulse-wave velocity (PWV), is also a risk factor for cardiovascular disease. The aims of this study were to determine the stiffness of the aorta in female adolescents with AN and to determine if either the severity or the type of AN was associated with PWV. METHODS This was a retrospective case-control study. Adolescent patients with a clinical diagnosis of AN were included. Aortic diameter and pulse-wave transit time over a portion of the thoracic aorta were measured using Doppler echocardiography, and PWV was calculated. RESULTS There were 94 female patients with AN and 60 adolescent female control subjects. There was no significant difference in age between patients with AN and control subjects (15.5 ± 1.7 vs 15.1 ± 2.6 years, P = .220). Body mass index (16.0 ± 2.4 vs 19.7 ± 2.7 kg/m2, P < .001) and body mass index percentile (9.4 ± 15.6 vs 45.5 ± 26.2, P < .001) were significantly lower for patients with AN than control subjects. PWV (443 ± 106 vs 383 ± 77 cm/sec, P < .001) was significantly higher in patients with AN than control subjects. Similar differences from control subjects were found in patients with AN with both lower and higher body mass index percentiles and also in patients with AN with the restrictive or the binge-purge subtype. CONCLUSIONS Female adolescents with AN have increased aortic stiffness compared with control subjects. This study suggests that patients with AN may be at increased risk for future cardiovascular disease. Future studies are required to determine the reversibility of these changes with weight restoration.
