title: Use of GATED-SPECT for Ventricular Desynchronization Evaluation in Patients with Heart Failure Submitted to Cardiac Resynchronization Therapy

description: Abstract Background: Approximately 20 to 40% of patients with heart failure do not respond to cardiac resynchronization therapy (CRT). To improve patient selection, phase analysis by myocardial perfusion scintigraphy (GSPECT) was developed. Objectives: To evaluate the clinical and scintigraphic response of patients with heart failure (HF) submitted to CRT using GSPECT. Method: This was an interventional study that included consecutive patients assessed by GSPECT four weeks prior to CRT implantation and six months after it for comparison. These patients also answered the Minnesota Living with Heart Failure Questionnaire (MLHFQ). The categorical variables were compared using Fisher's exact test and chi-square test, whereas Student's t-test was used for numerical variables. The level of statistical significance was set at 5%. The scintigraphic variables analyzed were left ventricular ejection fraction, end-systolic volume, end-diastolic volume, left ventricular mass, standard deviation and bandwidth, as well as QRS duration and the Minnesota Quality of Life Questionnaire score. The presence of mechanical dyssynchrony was defined as standard deviation &gt; 43º. Results: Nine patients were included in the study. After the cardiac resynchronization therapy, there was a significant improvement (p &lt; 0.05) in the end-systolic volume (206 ± 80 mL vs. 158 ± 108 mL), QRS (180 ± 18 ms vs. 120 ± 9 ms), left ventricular mass (248 ± 65 g vs. 193 ± 52 g) and Minnesota Quality of Life Questionnaire score (63 ± 16 vs. 34 ± 20). All patients with scintigraphic criteria of mechanical dyssynchrony showed clinical improvement. Two patients had only electrical dyssynchrony and did not achieve significant clinical improvement, although they showed QRS duration reduction. Conclusion: GSPECT was able to differentiate patients with isolated electrical dyssynchrony from those with associated mechanical dyssynchrony, through the intraventricular dyssynchrony parameters. The cardiac resynchronization therapy is associated with the improvement of both mechanical and electrical dyssynchrony. Pre-implantation GSPECT showed that patients with associated electrical and mechanical dyssynchrony had a better response to cardiac resynchronization therapy than those with isolated electrical dyssynchrony.

title: Acute Effect of Manual Lymphatic Drainage on Natriuresis and Lipolysis in Young Women

description: Abstract Background: The importance of scientific validation of supporting techniques to various treatments is unquestionable. In this context, the influence of manual lymphatic drainage (MLD) on natriuresis and lipolysis and its interaction with oral contraceptives still need to be investigated. Objectives: To evaluate the acute effect of MLD on natriuresis and lipolysis in young women using or not oral contraceptives. Methods: Twenty-nine non-users of oral contraceptives and 29 oral contraceptive users, self-reported healthy, sedentary, normal weight women were enrolled. Analyses were conducted on two different days - control (C), without therapeutic intervention and MLD day. Four urine samples were collected at 60-minute intervals. MLD was performed in lower limbs and abdomen for 45 min following the Leduc method. Urinary flow rate and urinary sodium, glycerol and atrial natriuretic peptide excretion were analyzed. Data normality was tested by the Shapiro-Wilk test. Data without normal distribution were expressed as median and interquartile range (25%-75%), while normally distributed data were expressed as mean ± standard error. Mann-Whitney test was used for unpaired data and Wilcoxon test for paired data. Data with normal distribution were evaluated by the unpaired t-Student test. Statistical significance was set at 5%. Results: One MLD session had an acute effect on both groups, increasing natriuresis in non-users of oral contraceptives and glycerol and atrial natriuretic peptide excretion in oral contraceptive users. Conclusion: Oral contraceptives influence the effect of MLD on natriuresis.

title: Evaluation of Lipid Profile in Adolescents

description: Abstract Background: Atherosclerosis is a chronic, multifactorial and insidious disease that can begin in childhood and adolescence, and whose major consequences appear during adulthood. Serum levels of lipoproteins, such as LDL-c, total cholesterol (TC), HDL-c, and non-HDL-c can be used as a screening method for disease diagnosis. In Brazil, few studies have correlated the serum levels of those lipoproteins with age. Objective: To evaluate the serum concentrations of TC, LDL-c, HDL-c, VLDL-c, non-HDL-c and triglycerides (TG) of adolescents aged 10 to 19 years in the municipality of Araucária, Paraná state. Methods: Cross-sectional retrospective study, collecting the following data from 600 adolescents: age, sex and serum levels of TC, LDL-c, HDL-c and TG from June to December 2016. Data were analyzed using the SPSS software 2.0, with Mann-Whitney U test and Spearman coefficient of correlation to identify statistical significance (p &lt; 0.05). Results: The female sex showed higher serum levels of TC, TG and LDL-c than the male sex. The HDL-c levels were identical in both sexes, with 48% of desirable values and 52% of low values. This study identified a strong correlation between the lipids and association with the age group of 10 to 14 years. Conclusion: Non-HDL-c showed stronger correlation with the other lipids (TG, LDL-c and TC) as compared to LDL-c, suggesting that non-HDL-c can be used as an effective complementary diagnostic method to assess the risks for atherosclerosis in adolescents.

title: Superior Cardiovascular Effect of the Periodized Model for Prescribed Exercises as Compared to the Conventional one in Coronary Diseases

description: Abstract Background: Physical exercise improves the survival and quality of life of coronary patients, but the ideal way of prescribing these exercises is still controversial. Objective: To create a new periodized model for the prescription of exercises for coronary patients and compare it with a conventional model. Methods: 62 coronary patients under pharmacological treatment were randomized into two groups: conventional (NPG, n = 33) and periodized (PG, n = 29) training. The two groups were submitted to the same exercises during the 36 sessions making up the program, but prescribed in different ways. All patients underwent an evaluation consisting of: medical admission consultancy, cardiopulmonary endurance testing, 1 maximum repetition test (1MR) and body composition evaluation. Results: The VO2 peak improved in both groups, although more effectively in the PG (4% against 1.7%, p &lt; 0.001). In addition, the functional capacity of this group improved by 13%, and there was a significant reduction in the percent body fat (2.1%, p &lt; 0.005) and body weight (1.9 kg, p &lt; 0.005). The muscle strength of both groups improved as diagnosed by the 1RM test for six different muscle groups (quadriceps, hamstrings, brachial biceps, brachial triceps, pectoral and large dorsal), and showed no significant difference between the groups, evidencing that the two models had the same efficiency. Conclusions: The present study showed that periodization of the training of cardiac patients can improve their cardiorespiratory capacity and reduce the percent body fat more effectively than the conventional one.

title: Fatigue: A Complex Symptom and its Impact on Cancer and Heart Failure

description: Abstract In chronic diseases like cancer and heart failure (HF), fatigue is a common and complex symptom from an etiological and pathophysiological point of view, thus, a relevant issue in the recent area of oncocardiology. Fatigue is prevalent in 80-90% of the oncological patients treated with chemotherapy and/or radiotherapy and affects approximately 50-96% of the individuals with IC. The toxicity attributed to chemotherapeutic agents can determine the patients’ degree of fatigue and may even predict their survival. In recent decades, the advancement of antineoplastic therapies has substantially impacted the survival of patients with cancer, and the risks of harmful effects from these therapies to the cardiovascular system have been increasingly described. Therefore, the cooperation between oncologists and cardiologists has led to the emergence of oncocardiology and the new concept of cardiac surveillance. Cardiotoxicity is one of the clinical complications in the treatment of cancer, and its typical manifestation is left ventricular systolic dysfunction. New diagnostic and therapeutic strategies have been employed in the cardiac surveillance of patients with cancer. Fatigue in these patients has been carefully studied with a multidisciplinary approach and with the development of visual scales to quantify and correlate better its real impact on these individuals’ quality of life and survival. The Fatigue Pictogram and Piper Fatigue Scale are tools increasingly used in research and clinical practice. The mechanisms involved in fatigue, from a conceptual point of view, may be of central (central nervous system) or peripheral (muscular skeletal) origin, both of which may be present in patients with cancer. The present review aims to discuss the new concepts in the assessment of fatigue in oncological patients. These concepts are fundamental to professionals who work in the emerging area of oncocardiology.

title: Telerehabilitation for Cardiac Patients: Systematic Review

description: Abstract Cardiovascular rehabilitation is one nonpharmacological intervention used to treat cardiovascular diseases. Despite the proven benefits of cardiovascular rehabilitation, the adherence of patients with heart disease is low. Thus, the alternative of telerehabilitation has gained importance, and many studies are being carried out to verify its efficacy. To review the literature and assess the efficacy of telerehabilitation for the cardiac population. This is a systematic review of the literature. The search was conducted in the electronic databases MEDLINE/PubMed (Medical Literature Analysis and Retrieval System Online), PubMed Central® (PMC), Cochrane Library, and Physiotherapy Evidence Database (PEDro), using the combination of descriptors, including terms of the Medical Subject Headings (MeSH) and its entry terms. The MeSH terms used in combination were: “telerehabilitation” AND “cardiac rehabilitation” (Table 1). Then, a manual search by use of the articles selected, as well as a search in the gray literature, was conducted. The search strategy collected 154 studies, of which 109 were excluded because of duplication in the databases and 29 for not being clinical studies. Sixteen clinical studies were included for full analysis, of which 2 were excluded for being prospective, 2 for being duplicate and 5 for not including any outcome. Thus, 7 studies were included. Cardiac rehabilitation using telerehabilitation is a feasible and safe alternative to conventional rehabilitation, and has high adherence of patients with heart disease. It can be added to conventional cardiovascular rehabilitation programs or used in isolation.
