Echocardiographic follow-up after cardiac rehabilitation designed for patients with obesity. THE INTERNATIONAL JOURNAL OF CARDIOVASCULAR IMAGING 2023; 39:945-954. [PMID: 36928518 PMCID: PMC10160212 DOI: 10.1007/s10554-023-02805-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Subscribe] [Scholar Register] [Received: 08/04/2022] [Accepted: 01/27/2023] [Indexed: 03/18/2023]
Abstract
We hypothesize that a novel tailor-made cardiac rehabilitation (CR) program for obesity patients (OPTICARE XL) has better outcomes as compared to usual CR regarding parameters of cardiac function as measured by conventional and advanced transthoracic echocardiography. This is an open-label, randomized controlled trial. Inclusion criteria were: patients referred to CR with a body mass index (BMI) ≥30 kg/m2, and age ≥18 years with either coronary artery disease or nonvalvular atrial fibrillation. The experimental group participated in OPTICARE XL and the controls received the usual CR. Subjects randomized to OPTICARE XL received on top of usual CR behavioural therapy for a healthy diet and an active lifestyle for the first 12 weeks. Also, the exercise program was more tailored. Furthermore, a behavioural after-care program was organized with 6 meetings between weeks 13-52. Transthoracic (speckle tracking) echocardiography was performed at baseline and one-year follow-up. A total of 42 patients completed the follow-up, 21 in both groups. There was a mild but statistically significant reduction in weight over time, however, this was comparable between groups. There was no improvement observed in any of the echocardiographic parameters. In conclusion, cardiac function in obesity patients was not improved one-year after a novel tailor-made CR program (OPTICARE XL) as compared to usual CR.

Abstract
Metabolic syndrome (MetS) includes different metabolic conditions (i.e. abdominal obesity, impaired glucose tolerance, hypertriglyceridemia, decreased HDL cholesterol, and/or hypertension) that concour in the development of cardiovascular disease and diabetes. MetS individuals often show adverse cardiac remodeling and myocardial dysfunction even in the absence of overt coronary artery disease or valvular affliction. Diastolic impairment and hypertrophy are hallmarks of MetS-related cardiac remodeling and represent the leading cause of heart failure with preserved ejection fraction (HFpEF). Altered cardiomyocyte function, increased neurohormonal tone, interstitial fibrosis, coronary microvascular dysfunction, and a myriad of metabolic abnormalities have all been implicated in the development and progression of adverse cardiac remodeling related to MetS. However, despite the enormous amount of literature produced on this argument, HF remains a leading cause of morbidity and mortality in such population. The early detection of initial adverse cardiac remodeling would enable the optimal implementation of effective therapies aiming at preventing the progression of the disease to the symptomatic phase. Beyond conventional imaging techniques, such as echocardiography, cardiac tomography, and magnetic resonance, novel post-processing tools and techniques provide information on the biological processes that underlie metabolic heart disease. In this review, we summarize the pathophysiology of MetS-related cardiac remodeling and illustrate the relevance of state-of-the-art multimodality cardiac imaging to identify and quantify the degree of myocardial involvement, prognosticate long-term clinical outcome, and potentially guide therapeutic strategies.

Abstract
Left ventricular diastolic function (LVDF) is an important marker of early cardiovascular remodelling, which has not been well summarized in young people with overweight/obesity. Weighted, random-effects regression was used to determine the strength of associations of both body mass index (BMI) and homeostatic model assessment of insulin resistance (HOMA-IR) with LVDF measures, adjusting for age and sex. Six databases were searched after PROSPERO registration (CRD42020177470) from inception to July 2020 for studies that compared LVDF between overweight/obesity and control groups aged ≤24 years, yielding 70 studies (9983 individuals). Quality and risk of bias were assessed using NHLBI tools, with scores of good, fair, and poor for 6, 48, and 16 studies, respectively. Increased BMI was associated with worse LVDF in all measures except early mitral inflow deceleration time, with septal early diastolic tissue peak velocity to late diastolic tissue peak velocity ratio having the strongest association (n = 13 studies, 1824 individuals; r = -0.69; P < 0.001). Elevated HOMA-IR was also associated with worse LVDF. Although we could not determine the causality of reduced LVDF in young people, our findings should aid the development of paediatric guidelines for the assessment of LVDF and support further work to address the longitudinal consequences of childhood obesity and IR on LVDF.

Abstract
AIMS We explored the early effects of bariatric surgery on subclinical myocardial function in individuals with severe obesity and preserved left ventricular (LV) ejection fraction. METHODS Thirty-eight patients with severe obesity [body mass index (BMI) ≥35 kg/m2] and preserved LV ejection fraction (≥50%) who underwent bariatric surgery (biliopancreatic diversion with duodenal switch [BPD-DS]) (Surgery group), 19 patients with severe obesity managed with usual care (Medical group), and 18 age and sex-matched non-obese controls (non-obese group) were included. Left ventricular global longitudinal strain (LV GLS) was evaluated with echocardiography speckle tracking imaging. Abnormal myocardial function was defined as LV GLS <18%. RESULTS Age of the participants was 42 ± 11 years with a BMI of 48 ± 8 kg/m2 (mean ± standard deviation); 82% were female. The percentage of total weight loss at 6 months after bariatric surgery was 26.3 ± 5.2%. Proportions of hypertension (61 vs. 30%, P = 0.0005), dyslipidemia (42 vs. 5%, P = 0.0001) and type 2 diabetes (40 vs. 13%, P = 0.002) were reduced postoperatively. Before surgery, patients with obesity displayed abnormal subclinical myocardial function vs. non-obese controls (LV GLS, 16.3 ± 2.5 vs. 19.6 ± 1.7%, P < 0.001). Six months after bariatric surgery, the subclinical myocardial function was comparable to non-obese (LV GLS, 18.2 ± 1.9 vs. 19.6 ± 1.7%, surgery vs. non-obese, P = NS). On the contrary, half of individuals with obesity managed medically worsened their myocardial function during the follow-up (P = 0.002). Improvement in subclinical myocardial function following bariatric surgery was associated with changes in abdominal visceral fat (r = 0.43, P < 0.05) and inflammatory markers (r = 0.45, P < 0.01), whereas no significant association was found with weight loss or change in insulin sensitivity (HOMA-IR) (P > 0.05). In a multivariate model, losing visceral fat mass was independently associated with improved subclinical myocardial function. CONCLUSIONS Bariatric surgery was associated with significant improvement in the metabolic profile and in subclinical myocardial function. Early improvement in subclinical myocardial function following bariatric surgery was related to a greater mobilization of visceral fat depot, linked to global fat dysfunction and cardiometabolic morbidity.

Impact of Lifestyle Intervention Programs for Children and Adolescents with Overweight or Obesity on Body Weight and Selected Cardiometabolic Factors-A Systematic Review.

Abstract
Excessive body mass is a health problem among children and adolescents that contributes to the occurrence of lipid disorders and abnormal blood pressure. Effective treatment of excessive body mass in children is essential for the health of population in the future. The aim of the study was to identify universal components of lifestyle interventions in children and adolescents with overweight or obesity leading to weight loss and improvement of selected cardiometabolic parameters. The review included studies from the PubMed and Google Scholar databases published in 2010–2019, which were analyzed for eligibility criteria including age of the participants, BMI defined as overweight or obese, nutritional intervention and the assessment of BMI and/or BMI z-score and at least one lipid profile parameter. Eighteen studies were included in the review, presenting the results of 23 intervention programs in which a total of 1587 children and adolescents participated. All interventions, except one, were multi-component. Data analysis suggests a relationship between a decrease in BMI and/or BMI z-score with diet and physical activity, the involvement of a dietician/nutrition specialist and physician in the treatment team and a longer duration of intervention. Moreover, it seems that a decrease in BMI is mostly associated with decreases in total cholesterol, triglycerides, low density lipoprotein cholesterol and blood pressure. No change in BMI and/or BMI z-score is associated with no change in blood pressure. Our data can be used by public health authorities to design effective weight loss programs for children and adolescents.

Abstract
Diabesity is a term used to describe the combined adverse health effects of obesity and diabetes mellitus. The worldwide dual epidemic of obesity and type 2 diabetes is an important public health issue. Projections estimate a sixfold increase in the number of adults with obesity in 40 years and an increase in the number of individuals with diabetes to 642 million by 2040. Increased adiposity is the strongest risk factor for developing diabetes. Early detection of the effects of diabesity on the cardiovascular system would enable the optimal implementation of effective therapies that prevent atherosclerosis progression, cardiac remodelling, and the resulting ischaemic heart disease and heart failure. Beyond conventional imaging techniques, such as echocardiography, CT and cardiac magnetic resonance, novel post-processing tools and techniques provide information on the biological processes that underlie metabolic heart disease. In this Review, we summarize the effects of obesity and diabetes on myocardial structure and function and illustrate the use of state-of-the-art multimodality cardiac imaging to elucidate the pathophysiology of myocardial dysfunction, prognosticate long-term clinical outcomes and potentially guide treatment strategies.

Abstract
Background: Using meta-regression, this article aims at establishing the minimum change in BMI-standard deviation score (SDS) needed to improve lipid profiles and blood pressure in children and adolescents with obesity, to aid future trials and guidelines. Methods: Studies with participants involved in lifestyle interventions, aged 4-19 years, with a diagnosis of obesity according to defined BMI thresholds, were considered for inclusion in a large systematic review. Interventions had to report pre- and post-intervention (or mean change in) BMI-SDS, plus either systolic blood pressure (SBP), high-density lipoprotein (HDL) cholesterol, low-density lipoprotein (LDL) cholesterol, and/or triglycerides (TGs). Random-effects meta-regression quantified the relationship between mean change in BMI-SDS and mean change in cardiovascular outcomes. Results: Seventy-one papers reported various cardiovascular measurements and mean change in BMI-SDS. Fifty-four, 59, 46, and 54 studies were analyzed, reporting a change in SBP, HDL, LDL, and TG, respectively. Reduction in mean BMI-SDS was significantly related to improvements in SBP, LDL, TG, and HDL (p < 0.05); BMI-SDS reductions of 1, 1.2, and 0.7 ensured a mean reduction of SBP, LDL, and TG, respectively, although an equivalent value for HDL improvement was indeterminate. Conclusion: Reductions in mean BMI-SDS of >1, >1.2, or >0.7 are likely to reduce SBP, LDL, and TG, respectively. Further studies are needed to clarify the optimal duration, intensity, and setting for interventions. Consistency is required regarding derived BMI values to facilitate future systematic reviews and meta-analyses.

Abstract
The reduction in body mass index standard deviation score (BMI-SDS) associated with improvement in biomarkers relating to metabolic health in obese children is unknown. We aimed to establish the change in BMI-SDS associated with improved inflammation, liver function, and insulin resistance to inform clinical guidelines for pediatric weight management interventions and to assess the efficacy of future trials. A large-scale systematic review was conducted to identify relevant studies. Studies of children with a diagnosis of obesity according to defined BMI thresholds, participating in lifestyle interventions to reduce obesity, were included. Studies must have reported baseline (pre-) and postintervention (or change of) BMI-SDS and either fasting glucose, homeostatic model of insulin resistance (HOMA-IR), alanine aminotransferase (ALT), C-reactive protein (CRP), or interleukin-6 (IL-6). A series of meta-regressions were conducted to establish links between BMI-SDS change scores and change in metabolic markers of health. Sixty-eight articles were identified. From the meta-regression analyses, across all study subsets, greater mean falls in all four parameters, (HOMA-IR, Glucose, ALT, and CRP) were observed with greater mean loss of BMI-SDS, but the trends were only statistically significant for HOMA-IR and CRP (P = .003; P = .021). However, we could not find minimum changes in BMI-SDS that would ensure a fall in these outcomes. At this time, we are unable to recommend a definitive value of BMI-SDS reduction needed to improve the markers of metabolic health. Future trials should aim to report additional indices of derived BMI values, which may better reflect changes in actual adiposity.

Abstract
BACKGROUND High intensity interval training (HIIT) confers superior cardiovascular health benefits to moderate intensity continuous training (MICT) in adults and may be efficacious for improving diminished cardiac function in obese children. The aim of this study was to compare the effects of HIIT, MICT and nutrition advice interventions on resting left ventricular (LV) peak systolic tissue velocity (S') in obese children. METHODS Ninety-nine obese children were randomised into one of three 12-week interventions, 1) HIIT [n = 33, 4 × 4 min bouts at 85-95% maximum heart rate (HRmax), 3 times/week] and nutrition advice, 2) MICT [n = 32, 44 min at 60-70% HRmax, 3 times/week] and nutrition advice, and 3) nutrition advice only (nutrition) [n = 34]. RESULTS Twelve weeks of HIIT and MICT were equally efficacious, but superior to nutrition, for normalising resting LV S' in children with obesity (estimated mean difference 1.0 cm/s, 95% confidence interval 0.5 to 1.6 cm/s, P < 0.001; estimated mean difference 0.7 cm/s, 95% confidence interval 0.2 to 1.3 cm/s, P = 0.010, respectively). CONCLUSIONS Twelve weeks of HIIT and MICT were superior to nutrition advice only for improving resting LV systolic function in obese children.

Abstract
Obesity is associated with an increased risk of heart failure. Little is known about the impact of dietary changes on the cardiac sequelae in obese patients. Twenty-one obese subjects underwent a 12-week low calorie fasting phase of a formula diet. Transthoracic two-dimensional speckle-tracking echocardiography was performed to obtain systolic left ventricular strain before and after weight loss. Body mass index decreased significantly from 38.6 ± 6.2 to 31.5 ± 5.3 kg/m(2), and the total percentage fat loss was 19%. Weight reduction was associated with a reduction in blood pressure and heart rate. Left ventricular longitudinal global peak systolic strain was in the lower normal range (-18.7 ± 3.2%) before weight loss and was unchanged (-18.8 ± 2.4%) after 12 weeks on diet with substantial weight loss. Also, no significant change in global radial strain after weight loss was noted (41.1 ± 22.0 versus 43.9 ± 23.3, p = 0.09). Left atrial and ventricular dimensions were in normal range before fasting and remained unchanged after weight loss. In our study obesity was associated with normal systolic left ventricular function. A 12-week low calorie diet with successful weight loss can reduce blood pressure and heart rate. Systolic left ventricular function and morphology were not affected by rapid weight reduction.

Abstract
OPINION STATEMENT Obesity is an independent predictor of heart failure in adults. Obese individuals have increased hemodynamic load and neuro-hormonal activation that contribute, but cannot entirely explain the reported changes in ventricular structure and function leading to heart failure. There are intrinsic alterations in the myocardium that are independent of load. Insulin resistance promotes alterations in myocardial substrate metabolism that may play a role in the pathogenesis of decreased myocardial efficiency and cardiac dysfunction in obese individuals. The prevalence of obesity in childhood and adolescence has increased significantly over the last decade. Obese children and adolescents have left ventricular remodeling that transpires into adulthood, and subclinical systolic and diastolic dysfunction despite normal conventional parameters of ventricular function. These findings suggest that obesity has an early impact in the cardiovascular health of obese adolescents. Life-style modifications causing weight loss can reverse the ventricular dysfunction observed in this young population and must be strongly encouraged.
