Interval Ratio

Background: The Tp-e/QT (peak to end of T-wave duration/QT interval) ratio is a promising marker of myocardial repolarization and ventricular arrhythmogenesis. Its elevation is associated with sudden cardiac death in different clinical conditions. This study was designed to assess the possible association between increased Tp-e/QT ratio and clinical factors in peritoneal dialysis patients. Materials & methods: We devised a prospective cross-sectional study, which included 107 patients who were divided into groups according to their Tp-e/QT ratio. The association of an increased Tp-e/QT ratio with related factors was analyzed with multivariate logistic regression. Results: Thirty-one patients, who had an elevated Tp-e/QT ratio, showed higher values of IL-6, left ventricular end-systolic diameter, Tp-e, percentage of diabetes mellitus, coronary artery calcification, and left ventricular ejection fraction. Multivariate analysis revealed that IL-6 was an independent risk factor for a higher Tp-e/QT ratio after adjustments. Conclusion: Our study revealed that a high serum IL-6 level in peritoneal dialysis patients increased the risk of a higher Tp-e/QT ratio, which indicated a potentially hazardous interplay between inflammation and arrhythmogenesis.

AbstractBackgroundThe global prevalence of obesity in school-age children and adolescents has increased in recent decades. Obesity modifies some aspects of the cardiovascular system in order to preserve the body homoeostasis. Echocardiography to study ventricular function plays an important role in the evaluation of pathological re-modelling associated with left ventricular dysfunction. The aim of this study was to evaluate the left ventricle function and structure with conventional echocardiography and to analyse the longitudinal deformity of the left ventricle using myocardial-tracking signals in a group of severely obese adolescents.Methods and resultsWe carried out a descriptive cross-sectional study. We describe the evaluation of the left ventricle using conventional bi-dimensional echocardiography and the myocardial-tracking signals in severely obese adolescents. There were 34 severely obese adolescents included in our study; 52% had a left ventricular ejection fraction<55%, the left ventricular end-diastolic diameter was increased in 70.5% of patients, and 32.3% had an increase in left ventricular mass. On average, 78.9% had abnormal values of left ventricle longitudinal deformations. The number of segments affected per patient was, on average, 5.8, with the anterior apical segment being the most commonly affected. There was a decrease in global longitudinal deformity in 79.4% of the cases.ConclusionMore than half of this group of asymptomatic severely obese adolescents showed abnormalities in left ventricular structure and function evaluated using traditional echocardiographic methods, but 100% of the cases showed abnormalities in longitudinal deformation in at least one of the 17 left ventricle segments evaluated using myocardial-tracking signals.

Active Acromegaly

Abstract Background: The GH receptor (GHR) exon 3 polymorphism occurs at a genomic level. Approximately 50-60% of the population is homozygous for the exon-3 containing genotype (+3/+3), 30-40% are heterozygous (+3/-3) and 10-20% are homozygous for the exon-3 lacking genotype (-3/-3). Some studies suggest that children homo- and heterozygous for the GHR exon 3 lacking genotype (-more efficient 3/-3 and +3/-3, respectively) respond better to treatment with exogenous rhGH and there is also in vitro evidence showing a more efficient signal transduction through this exon 3 deleted isoform. Some studies have found that patients with acromegaly harboring the exon 3-deleted genotype may have a higher prevalence of diabetes and hypertension. Hypothesis and Objective: Patients with active acromegaly harboring the exon 3-lacking GHR genotype may have more echocardiographic abnormalities than those who are homozygous for the exon 3 containing genotype. Patients and Methods: This is a cross-sectional study of patients with active acromegaly, defined by an IGF-1 level &gt; 1.3 times the upper limit of normal (x ULN), who underwent transthoracic echocardiography. Exon-3 GHR genotype was determined by PCR using previously described sense and antisense primers. Results: The cohort consisted of 28 patients, 54% female, with a mean age of 51 ± 12 years. Mean disease duration at the time of echocardiographic examination was 4.48 ± 4.7 years; median basal GH and IGF-1 were 12 ± 26 ng/mL and 2.4 ± 1.04 x ULN. The prevalence of hypertension and diabetes were 43% and 36%, respectively. Fifty three percent of the patients were homozygous for the exon 3-containaing genotype (+3/+3), 18% were homozygous for the exon 3-lacking genotype (-3/-3) and 29% were heterozygous (+3/-3). Clinical and biochemical features did not differ between patients with the different GHR genotypes, except for hypertension that was more prevalent in the +3/+3 genotype group (60% vs 23%, p= 0.04). The frequency of the different echocardiographic parameters was similar among groups (left ventricular hypertrophy 33% vs 15%, p= 0.27; diastolic dysfunction 47% vs 31%, p= 0.39; subclinical systolic dysfunction 42% vs 54%, p= 0.54; left ventricular ejection fraction 59±10% vs 60±16%, p= 0.83); aortic valve abnormalities 19% vs 15%, p=0.63; mitral valve abnormalities 46% vs 15%, p=0.07). Conclusions: Echocardiographic abnormalities in patients with active acromegaly do not differ among patients with the different GHR exon 3 genotypes. The clinical spectrum of acromegaly varies considerably. Although such variability is usually related to the severity of the hypersomatotropinemia, in many patients this is not the case.

Abstract Background: Methadone is a synthetic opioid mostly used for detoxification therapy, as its use increases; the possibility for methadone-induced cardiotoxicity may rise. The aim of this study was to determine the association of high-sensitivity troponin I levels as a predictor of cardiac injury in methadone toxicity.Methods: Sixty methadone toxicity patients included in this prospective cross-sectional study from October 2018-November 2020. High-sensitivity troponin I level and electrocardiogram were assessed in patients at admission. All patients underwent echocardiography at admission and 30 days later and compared this findings between two groups based on high-sensitivity troponin I results.Results: Mean age of the patients was 34.5±11.1 years (males: 66%). Twelve (20%) patients had positive high sensitive-troponin results. Long QT interval and inverted T in precordial leads were mostly observed in individuals with positive high-sensitivity troponin I (75% vs. 35%, P=0.013 and 83% vs. 16%, P<0.001, respectively). Patients with elevated troponin had reduced left ventricular ejection fraction in comparison to normal group during admission (43.1±15.4% vs. 55%, P<0.001) and this left ventricular ejection fraction remained abnormal after 30 days (43.7±21.6%). Patients in positive high-sensitivity troponin I group had higher regional wall motion abnormality frequency both at admission and 30 days later compared to the other group (0 day: 42% vs. 0, P<0.001, 30th days: 25% vs. 4%, P=0.020).Conclusion: Patients with simultaneous methadone toxicity and positive high-sensitivity troponin I had worse cardiac outcomes and this biomarker could be probably used for better implementation of therapeutic interventions and prognosis.

ABSTRACT Objective: To compare the distributions of measurements of the Dutch Fatigue Scale (DUFS), Dutch Exertion Fatigue Scale (DEFS), and Fatigue Pictogram tools, according to the New York Heart Association (NYHA) Functional Classification and left ventricular ejection fraction (LVEF). Method: Methodological, cross-sectional study with 118 patients with heart failure. Variance analysis, Pearson's correlation, and Fisher's exact tests were carried out, with a significance level of 0.05. Results: There was an increase in the DUFS and DEFS means with worsening of the NYHA-FC (p<0.001, for both tools). Correlations among the LVEF resulted in positive and weak magnitude for the DEFS (r=0.18; p=0.05) and for the DUFS (r=0.16; p=0.08). Just the item A on the Fatigue Pictogram had an association with the NYHA-FC (p<0.001) and the LVEF (p=0.03). Conclusion: Three tools detected worsening in fatigue levels according to the illness severity assessed by the NYHA-FC.

Early Predictor

Background and Aims: Left ventricular systolic dysfunction, even asymptomatic, is associated with the development of heart failure (HF) and all-cause mortality. Left ventricular ejection fraction (LVEF) is the most commonly used marker of left ventricular systolic function. It is well established that early detection and treatment of reduced LVEF, as well as the aggressive management of predisposing conditions, delays the manifestation of HF. Our study aimed to measure the association between LVEF and other echocardiographic variables in a population with LVEF within the normal range and without symptoms of HF. Methods: We conducted a cross-sectional study in 2008-2009. Results: We analyzed echocardiographic and clinical data of 146 patients: 66.4% were women; mean age was 55 (40 –69 years). LVEF significantly correlated only with left atrium (LA) size (Beta -0.266, p < 0.05). The correlation was inverse and remained significant after adjusting for age, gender, obesity, diabetes, arterial hypertension, left ventricular hypertrophy, pulmonary systolic pressure, mitral regurgitation, and diastolic dysfunction. Conclusions: We found that the earliest structural change associated with LVEF tendency to decrease was LA size. Further research is needed to assess the LA enlargement as an early predictor of systolic dysfunction development.

Ultrafiltration Failure

Introduction: Serum cancer antigen 125(SeCA125) has been reported to be increased in patients with heart failure and correlate with both extracellular water (ECW) overload and poor prognosis. Ultrafiltration failure and ECW overload are a major cause of peritoneal dialysis (PD) technique failure. We wished to determine whether SeCA125 could also be a marker of volume status in PD patients. Methods: We contemporaneously measured SeCA125, serum N terminal brain natriuretic peptide (NTproBNP) and ECW by bioimpedance in adult PD patients attending for outpatient assessment of peritoneal membrane function. Results: The median SeCA125 was 19 (12–33) U/mL in 489 PD patients, 61.3% male, median age 61.5 (interquartile range 50–75) years. SeCA125 was positively associated with the ratio of ECW/total body water (TBW) ( r = 0.29, p < 0.001), 4-h peritoneal dialysate to serum creatinine ratio ( r = 0.23, p < 0.001), NTproBNP) ( r = 0.18, p < 0.001), and age ( r = 00.17, p = 0.001) and negatively with 24-h PD ultrafiltration volume ( r = −0.28, p < 0.001) serum albumin ( r = −0.22, p < 0.001), and echocardiographic left ventricular ejection fraction ( r = −0.20, p < 0.001), but not with residual renal function or C-reactive protein. Patients with above the median SeCA125, had greater median ECW/TBW 0.403(IQR 0.394–0.410) vs 0.395(0.387–0.404), p < 0.001 and NTproBNP (6870 (IQR 1936–20096) vs 4069 (1345–12291) vs) pg/mL, p = 0.03. Conclusion: Heart failure studies have reported SeCA125 is a marker of ECW overload. Our retrospective analysis suggests that SeCA125 is also associated with ECW volume in PD patients. Further studies are required to determine whether serial measurements of SeCA125 trend with changes in ECW status in PD patients and can be used to aid volume assessments.

Heart failure (HF) is a major cause of morbidity and mortality. Extracorporeal (EC) therapy, including ultrafiltration (UF) and haemodialysis (HD), peritoneal dialysis (PD) and peritoneal ultrafiltration (PUF) are potential therapeutic options in diuretic-resistant states. This systematic review assessed outcomes of PD and compared the effects of PD to EC. A comprehensive search of major databases from 1966 to 2017 for studies utilising PD (or PUF) in diuretic-resistant HF was conducted, excluding studies involving patients with end-stage kidney disease. Data were extracted and combined using a random-effects model, expressed as odds ratio (OR). Thirty-one studies ( n = 902) were identified from 3195 citations. None were randomised trials. Survival was variable (0–100%) with a wide follow-up duration (36 h–10 years). With follow-up > 1 year, the overall mortality was 48.3%. Only four studies compared PD with EC. Survival was 42.1% with PD and 45.0% with EC; the pooled effect did not favour either (OR 0.80; 95% confidence interval (CI): 0.24–2.69; p = 0.710). Studies on PD in patients with HF reported several benefits. Left ventricular ejection fraction (LVEF) improved after PD (OR 3.76, 95%CI: 2.24–5.27; p < 0.001). Seven of nine studies saw LVEF increase by > 10%. Twenty-one studies reported the New York Heart Association status and 40–100% of the patients improved by ≥ 1 grade. Nine of 10 studies reported reductions in hospitalisation frequency and/or duration. When treated with PD, HF patients had fewer symptoms, lower hospital admissions and duration compared to diuretic therapy. However, there is inadequate evidence comparing PD versus UF or HD. Further studies comparing these modalities in diuretic-resistant HF should be conducted.
