RESUMEN

BACKGROUND: Trimetazidine (TMZ) modulates cardiac metabolism, but its use in heart failure remains controversial. The aim of the study was to evaluate the effects of TMZ on exercise capacity, left ventricular ejection fraction (LVEF), mortality, and quality of life in stable patients with heart failure with reduced left ventricular ejection fraction (HFrEF). METHODS: Forty-five patients with stable advanced HFrEF treated with optimal medical therapy were randomized in a prospective, single-center, open-label, cross-over study of trimetazidine (35 mg b.i.d.) on top of standard medical therapy or standard pharmacotherapy for two periods of 30 days and one period of 6 months. Initially and at the end of each period all patients underwent the following: exercise testing, six-minute walk test (6MWT), two-dimensional-echocardiography, and quality of life assessment. RESULTS: The mean age of patients was 58.2 ± 10.6 years. Etiology of HFrEF was ischemic in 66.6% of patients. After 6 months no significant changes were observed in either group with regards to peak VO2 uptake, 6MWT, LVEF, or quality of life. TMZ had no effect on mortality or cardiovascular events. CONCLUSIONS: The additional use of TMZ on top of standard medical therapy in stable advanced HFrEF patients was not associated with significant changes in mortality, exercise capacity, LVEF, or quality of life.

RESUMEN

Cardiopulmonary exercise testing (CPET) is an important diagnostic tool in contemporary clinical practice. This document presents an expert opinion from the Working Group on Cardiac Rehabilitation and Exercise Physiology of the Polish Cardiac Society concerning the indications, performance technique, and interpretation of results for CPET in adult cardiology. CPET is an electrocardiographic exercise test expanded with exercise evaluation of ventilatory and gas exchange parameters. It allows for a global assessment of the exercise performance including the pulmonary, cardiovascular, hematopoietic, neuropsychological, and musculoskeletal systems. It provides a noninvasive dynamic evaluation during exercise and is a reference modality for exercise capacity assessment. Moreover, it allows the measurement of numerous prognostic parameters. It is useful in cardiology, pulmonology, oncology, perioperative assessment, rehabilitation as well as in sports medicine and in the evaluation of healthy people. This test not only helps to diagnose the causes of exercise intolerance but also supports the evaluation of the treatment. New opportunities are offered by combining CPET with imaging such as exercise stress echocardiography. These tests are complementary and synergistic in their diagnostic and prognostic strength.

RESUMEN

INTRODUCTION Obesity impacts the global population. Bioelectrical impedance analysis (BIA) and cardiopulmonary exercise test [CPET]) may help modify the treatment. OBJECTIVES We aimed to compare BIA and CPET results in obese and lean indivisuals, assess changes in BIA and CPET during obesity treatment, and indentify parameters predicting treatment outcome. PATIENTS AND METHODS We enrolled 200 obese patients, of whom 45 underwent a lifestyle modification treatment, and 32 lean individuals (controls). Lifestyle modifications included diet, rehabilitation, education, and behavioral therapy. The diet was based on body composition assessed by BIA and fat metabolism assessed by CPET. The intensity of exercise in the rehabilitation program was based on CPET, mainly peak oxygen uptake (VO2peak), fat metabolism (FAT), and fat heart rate (FAT HR). The protocol duration was 12 weeks. RESULTS Obese patients differed from lean controls with regard to VO2peak (P <0.0001), oxygen uptake at anaerobic threshold (P <0.0002), respiratory exchange ratio (P <0.014), oxygen uptake to work rate slope (P <0.0004), FAT (P <0.001), FAT HR (P <0.0008), anaerobic threshold heart rate (P <0.0003), as well as fat mass (P = 0.01), fat­free mass (P = 0.007), resting metabolic rate (RMR) (P = 0.007), total body water (P = 0.01), and extracellular water (P = 0.004). The treatment resulted in increased RMR (P <0.02) and VO2peak (P <0.002), as well as reduced fat tissue (P <0.006) and resting heart rate (P <0.017). The prediction model based on FAT HR, resting heart rate, and FAT enabled the prediction of treatment outcomes in 92% of patients. CONCLUSIONS Obese patients had pathological FAT and impaired exercise tolerance. Changes in BIA and CPET prove the metabolic impact of lifestyle modification treatment.

RESUMEN

Comprehensive rehabilitation programs have so far been developed for many chronic diseases. It has been proven that their use can be safe and effective in lung diseases such as chronic obstructive pulmonary disease. There are still no standards of rehabilitation in the group of patients with sarcoidosis available. This situation results mainly from a small number of large, randomized studies concerning this topic. The available literature, however, allows defining some general rules in this field. It also provides evidence for the effectiveness of rehabilitation in reducing symptoms, improving the quality of life and prognosis in patients with sarcoidosis. Interventions such as endurance and strength training, including inspiratory muscle training, have been applied. Further research is necessary to confirm these data.

RESUMEN

INTRODUCTION The obesity pandemic requires development of methods that could be used on a large scale, such as the cardiopulmonary exercise test (CPET). Gene expression may explain CPET results on the molecular level. OBJECTIVES The aim of this study was to compare gene expression in obesity, depending on CPET results. PATIENTS AND METHODS The study group consisted of 9 obese patients and 7 controls. The treatment encompassed diet, rehabilitation, and behavioral therapy. Diet was based on the body composition analyzed by bioelectrical impedance, resting metabolic rate, and subjective patient preferences. The rehabilitation depended on the CPET results: maximal oxygen uptake and fatty acid metabolism. Behavioral intervention focused on the diagnosis of health problems leading to obesity, lifestyle modification, training in self­assessment, and development of healthy habits. The intensive treatment lasted for 12 weeks and consisted of consultations with a physician, dietitian, and medical rehabilitation specialist. RNA was isolated from the whole blood. A total of 47 323 transcripts were analyzed, of which 32 379 entities were confirmed to have high quality of RNA. RESULTS We observed differences in gene expression related to the CPET results indicating abnormalities in fat oxidation and maximal oxygen uptake. The genes with major differences in expression were: CLEC12A, HLA­DRB1, HLA­DRB4, HLA­A29.1, IFIT1, and LOC100133662. CONCLUSIONS The differences in gene expression may account for the outcomes of treatment related to inflammation caused by obesity, which affects the muscles, fat tissue, and fatty acid metabolism.

RESUMEN

Congenital heart defects (CHD) are the cause of reduced physical performance. The presence of congenital abnormalities in the heart of grown-up patients contributes to excessive hypo-kinesia. We present endurance parameters and a personalized comprehensive cardiac rehabilitation program before an extreme mountain climbing of a 27-year-old patient with an uncorrected ventricular septal defect (VSD). A 26-year-old female patient with an uncorrected congenital VSD was admitted to the department of cardiac rehabilitation before the planned high-mountain expedition. Professional preparation and assessment of actual exercise capacity was performed before scheduled extreme climbing. We conclude that physical activity associated with a heavy load in people with uncorrected CHD who have not developed pulmonary hypertension and reverse right-to-left flow seems to be safe, while participation of grown-up patients with congenital heart disease (GUCH) in extreme mountain climbing requires special preparation, individually designed endurance training and education program, conducted by the team of professionals in specialist centers.

RESUMEN

INTRODUCTION: Concomitant obesity significantly impairs asthma control. Obese asthmatics show more severe symptoms and an increased use of medications. OBJECTIVES: The primary aim of the study was to identify genes that are differentially expressed in the peripheral blood of asthmatic patients with obesity, asthmatic patients with normal body mass, and obese patients without asthma. Secondly, we investigated whether the analysis of gene expression in peripheral blood may be helpful in the differential diagnosis of obese patients who present with symptoms similar to asthma. PATIENTS AND METHODS: The study group included 15 patients with asthma (9 obese and 6 normal-weight patients), while the control group-13 obese patients in whom asthma was excluded. The analysis of whole-genome expression was performed on RNA samples isolated from peripheral blood. RESULTS: The comparison of gene expression profiles between asthmatic patients with obesity and those with normal body mass revealed a significant difference in 6 genes. The comparison of the expression between controls and normal-weight patients with asthma showed a significant difference in 23 genes. The analysis of genes with a different expression revealed a group of transcripts that may be related to an increased body mass (PI3, LOC100008589, RPS6KA3, LOC441763, IFIT1, and LOC100133565). Based on gene expression results, a prediction model was constructed, which allowed to correctly classify 92% of obese controls and 89% of obese asthmatic patients, resulting in the overall accuracy of the model of 90.9%. CONCLUSIONS: The results of our study showed significant differences in gene expression between obese asthmatic patients compared with asthmatic patients with normal body mass as well as in obese patients without asthma compared with asthmatic patients with normal body mass.

RESUMEN

OBJECTIVES: Legislators and policymakers have expressed strong interest in intervention programs to reduce dependence on social disability benefits. Hybrid: ambulatory followed by home-based cardiac telerehabilitation--hybrid cardiac rehabilitation (HCR) seems to be a novel alternative for standard cardiac rehabilitation for patients with cardiovascular diseases (CVD) as a form of pension prevention paid by the Social Insurance Institution (SII). The kind of professional status may bias the motivation to return to work after HCR. The aim of our study was to evaluate whether the professional status can affect the effects of HCR. MATERIAL AND METHODS: One hundred fifty-two patients with CVD referred by the SII for a 5-week HCR were qualified for the study. Patients (87.7% males), aged 57.31 ± 5.61 years, were divided into 2 subgroups: W) white-collar employees (N = 22) and B) blue-collar employees (N = 130). To evaluate functional capacity, an exercise test on a treadmill was used. RESULTS: The number of days of absence in the cardiac rehabilitation program did not differ between the groups (mean ± standard deviation--B: 1.09 ± 3.10 days, W: 1.95 ± 3.64 days). There were significant improvements (p < 0.05) in measured variables after HCR in both (W and B) groups (max workload: 8.21 ± 2.88 METs (measured in metabolic equivalents) vs. 9.6 ± 2.49 METs, 7.76 ± 2.51 METs vs. 8.73 ± 2.7 METs, resting heart rate (RHR): 77 ± 16.22 bpm vs. 69.94 ± 12.93 bpm, 79.59 ± 14 bpm vs. 75.24 ± 11.87 bpm; double product, i.e., product of heart rate and systolic BP (DP rest) 10 815.22 ± 2968.24 vs. 9242.94 ± 1923.08, 10 927.62 ± 2508.47 vs. 9929.7 ± 2304.94). In group B, a decrease in systolic blood pressure (BP syst. - 137.03 ± 17.14 mm Hg vs. 131.82 ± 21.13 mm Hg), heart rate recovery in the 1st minute after the end of peak exercise (HRR1) (99.38 ± 19.25 vs. 93.9 ± 19.48) and New York Heart Association (NYHA) class (1.22 ± 0.53 vs. 1.11 ± 0.36) was observed. In group W, a decrease in diastolic blood pressure (BP diast.) at rest was observed (88.28 ± 9.79 mm Hg vs. 83.39 ± 8.95 mm Hg). The decrease in resting HR was significantly greater in group W (69.94 ± 12.93 vs. 75.24 ± 11.87, p = 0.034). CONCLUSIONS: Hybrid cardiac rehabilitation is feasible and safe with high adherence to the program regardless of the patient's professional status. Professional status did not influence the beneficial effect of HCR on exercise tolerance.

RESUMEN

BACKGROUND: Cardiac rehabilitation (CR) has been shown to reduce the cardiovascular mortality of patients with coronary artery disease (CAD) and help people to return to professional work. Unfortunately, limited accessibility and low participation levels present persistent challenges in almost all countries where CR is available. Applying telerehabilitation provides an opportunity to improve the implementation of and adherence to CR, and it seems that the hybrid form of training may be the optimal approach due to its cost-effectiveness and feasibility for patients referred by a social insurance institution. AIM: To present the clinical characteristics and evaluate the effects of hybrid: outpatient followed by home-based cardiac telerehabilitation in patients with CAD in terms of exercise tolerance, safety, and adherence to the programme. METHODS: A total of 125 patients (112 men, 13 women) with CAD, aged 58.3 ± 4.5 years, underwent a five-week training programme (TP) consisting of 19-22 exercise training sessions. The first stage of TP was performed in the ambulatory form of CR in hospital; then, patients continued to be telemonitored TP at home (hybrid model of cardiac rehabilitation - HCR). Before and after completing CR, all patients underwent a symptom-limited treadmill exercise stress test. Adherence was reported by the number of dropouts from the TP. RESULTS: The number of days of absence in the HCR programme was 1.50 ± 4.07 days. There were significant improvements (p < 0.05) in some measured variables after HCR in the exercise test: max. workload: 7.86 ± 2.59 METs vs. 8.88 ± 2.67 METs; heart rate (HR) at rest: 77.59 ± 12.53 bpm vs. 73.01 ± 11.57 bpm; systolic blood pressure at rest: 136.69 ± 17.19 mm Hg vs. 130.92 ± 18.95 mm Hg; double product at rest: 10623.33 ± 2262.97 vs. 9567.50 ± 2116.81; HRR1: 97.46 ± 18.27 bpm vs. 91.07 ± 19.19 bpm; and, NYHA class: 1.18 ± 0.48 vs. 1.12 ± 0.35. CONCLUSIONS: In patients with documented CAD, HCR is feasible and safe, and adherence is good. Most patients were on social rehabilitation benefit, had a smoking history, and suffered from hypertension, obesity, or were overweight. A hybrid model of CR improved exercise tolerance.

RESUMEN

BACKGROUND: The effectiveness of stationary and ambulatory cardiac rehabilitation of patients with coronary artery disease (CAD) and diabetes has been proven by some authors, but data concerning the effects of hybrid forms of cardiac rehabilitation (HCR) in this population are lacking. A home-based telerehabilitation is a promising form of secondary prevention of cardiovascular diseases in this group of patients. AIM: The objective of the study was to compare the effects of HCR in CAD patients with and without diabetes mellitus (DM). The secondary endpoint was the assessment of CAD risk factors like low exercise capacity and obesity, in both groups of patients. METHODS: This was a retrospective study, which comprised 125 patients with CAD aged 57.31 ± 5.61 years referred for HCR. They were assigned to Group D (with diabetes; n = 37) or Group C (without diabetes; n = 88). HCR was carried out as a comprehensive procedure that included all core components of cardiac rehabilitation according to guidelines. Before and after HCR all patients underwent a symptom-limited exercise test performed according to the Bruce protocol on a treadmill. RESULTS: Before HCR the maximal workload was higher in Group C than in Group D (8.13 ± 2.82 METs vs. 6.77 ± 1.88 METs; p = 0.023), but after HCR the difference was not significant. In both groups an increase in the maximal workload after HCR was observed (Group D: before HCR 6.81 ± 1.91 METs, after HCR 8.30 ± 2.04 METs; p < 0.001; Group C: before HCR 8.31 ± 2.71 METs, after HCR 9.13 ± 2.87 METs; p = 0.001). Resting heart rate, double product, and heart rate recovery 1 (HRR1) declined in both groups. No significant differences in changes in exercise test parameters between both groups' parameters were found. CONCLUSIONS: HCR was effective in patients with DM. The adherence was high. Patients with DM had higher rates of obesity and significantly lower exercise tolerance than patients without DM. Patients from both groups gained similar benefit from HCR in terms of physical capacity, resting heart rate, and heart rate recovery.

RESUMEN

BACKGROUND: Comprehensive cardiac rehabilitation (CCR) is an important element of the comprehensive management of grown-up congenital heart disease (GUCH) patients after surgical correction of congenital heart disease (CHD) but access to this treatment is still limited. We still lack Polish guidelines on CCR, including controlled training in young adults several years after surgical correction of CHD. AIM: To assess the effect of a CCR program on physical capacity, exercise tolerance, quality of life, and severity of depressive symptoms in GUCH patients long-term after surgical correction of CHD. METHODS: We studied 57 CHD patients (30 females, 27 males, mean age 23 ± 3.4 years) at least 12 months after surgical correction of a ventricular septal defect (VSD) or ostium secundum atrial septal defect (ASD II). All patients were offered a CCR program, and 31 of them participated (rehabilitation group [Reh]) and 26 refused (non-rehabilitated group [NReh]). All patients underwent baseline cardiopulmonary exercise testing (CPET) using a cycloergometer and a ramp protocol with an initial load of 20 W followed by 10 W load increments per minute. Psychological evaluation included the Beck Depression Inventory (BDI) and the Euro QoL 5D questionnaire to evaluate quality of life. Patients were reassessed 30 days after the initial evaluation using the same investigations. RESULTS: During CPET, all patients reached peak exercise intensity at the level of 15-17 in the Borg scale without complications. Resting HR was lower in the Reh group (74 ± 8 bpm) compared to the NReh group (81 ± 14 bpm). During CPET, patients in the Reh group reached significantly higher peak HR and percent maximum HR. Workload increased nonsignificantly (144 W vs. 124 W, p = 0.121), while duration of exercise and peak oxygen consumption was significantly longer in the Reh group compared to the NReh group (14 min vs. 11 min, p = 0.001; and 27.5 mL/kg/min vs. 23 mL/kg/min, p = 0.003, respectively). Patients in the NReh group showed non significantly higher severity of depressive symptoms compared to the Reh group, as evaluated using BDI at 30 days (mean score 4.8 vs. 2.2, respectively, p = 0.59). In contrast, subjectively and objectively rated quality of life was significantly higher in the Reh group compared to the NReh (score 89 vs. 74.4, p < 0.01; and 94 vs. 83, p < 0.01, respectively). CONCLUSIONS: Implementation of a CCR program improves physical capacity, exercise tolerance, and quality of life and reduces depressive symptoms in patients late after surgical correction of CHD. Introduction of such programs seems reasonable as a supplement to the holistic care for GUCH patients.

RESUMEN

In patients with heart failure treated with cardiac resynchronisation therapy (CRT), proper programming of the device can enhance the benefits of stimulation. Nowadays, adjustment of atrio-ventricular delay (AVD) is usually guided by echocardiography and performed only in resting conditions. The issue of optimal CRT programming during exercise, and the decision regarding the use of rate-adaptive pacing and rate-adaptive AVD algorithm during CRT, are largely empirical. We present a case report, and we indicate that programming of rate-adaptive pacing and rate-adaptive AVD algorithm on the basis of extended echocardiographic evaluation can further benefit the individual patient.
