RESUMEN
Cardiovascular disease (CVD) risk factors have been associated with CVD mortality, and physicians use CVD risk factor profiles (smoking, dyslipidemia, hypertension, etc.) to address patient health. Furthermore, cardio-respiratory fitness (CRF) has been shown to be an independent risk factor for CVD and all-cause mortality. Cardio-respiratory fitness is also the risk factor that contributes the highest percentage to all-cause deaths when compared to other traditional risk factors. In addition, studies have reported that adding CRF to established CVD risk factors improves the precision of prediction for CVD morbidity and mortality. Medical students tend to adopt sedentary and unhealthy lifestyles during the course of their education that negatively affect CVD risk factors and CRF. The majority of research on CVD risk, health status and lifestyle factors of medical students has used self-reported data and questionnaires for CVD risk factors and not included CRF in the health status measurements. In addition, studies have found that future medical doctors' own health and lifestyle practices influence their counselling activities. Allowing future medical doctors to assess their personal CVD risk factors and CRF may thus be important in their use of physical activity counselling with patients' lifestyle management for health benefits and improvement. A descriptive, cross-sectional cohort study design was used with the aim to determine CVD risk factors using CRF measures and physical activity levels in a cohort of South African medical students. The most significant finding was that they were not meeting the PA levels recommended to maintain health and lower CVD risk.
RESUMEN
Background. It is hypothesized that normal weight individuals develop diabetes through different pathophysiological mechanisms and that methods of prevention may differ in the absence of overweight/obesity. In this study, we compared the effect of lifestyle health coaching (LHC) on fasting plasma glucose (FPG) in normal weight, overweight, and obese US adults with prediabetes. Methods. Subjects were 1358 individuals who completed baseline and follow-up evaluations as part of an LHC program (follow-up = ~6 months). Participants were stratified, based on baseline body mass index (BMI), into normal weight (n = 129), overweight (n = 345), and obese (n = 884) cohorts. LHC included counseling, predominantly via telehealth, on exercise and nutrition. Results. BMI decreased (P < .001) in the overweight and obese participants but was unchanged in the normal weight participants. FPG decreased (P < .001) in all 3 cohorts, and the magnitude of decrease did not differ significantly among cohorts. FPG decreased to <5.6 mmol/L in 58.1%, 49.3%, and 41.4% of the normal weight, overweight, and obese participants, respectively. Conclusions. To our knowledge, this study is the first outside of Asia to show that LHC is as effective in managing FPG in normal weight adults with prediabetes versus those who are overweight/obese.
RESUMEN
BACKGROUND: Cardiovascular disease (CVD) is the leading cause of death worldwide. Despite strong evidence supporting the benefits of cardiac rehabilitation (CR), over 80% of eligible patients do not participate in CR. Digital health technologies (ie, the delivery of care using the internet, wearable devices, and mobile apps) have the potential to address the challenges associated with traditional facility-based CR programs, but little is known about the comprehensiveness of these interventions to serve as digital approaches to CR. Overall, there is a lack of a systematic evaluation of the current literature on digital interventions for CR. OBJECTIVE: The objective of this systematic literature review is to provide an in-depth analysis of the potential of digital health technologies to address the challenges associated with traditional CR. Through this review, we aim to summarize the current literature on digital interventions for CR, identify the key components of CR that have been successfully addressed through digital interventions, and describe the gaps in research that need to be addressed for sustainable and scalable digital CR interventions. METHODS: Our strategy for identifying the primary literature pertaining to CR with digital solutions (defined as technology employed to deliver remote care beyond the use of the telephone) included a consultation with an expert in the field of digital CR and searches of the PubMed (MEDLINE), Embase, CINAHL, and Cochrane databases for original studies published from January 1990 to October 2018. RESULTS: Our search returned 31 eligible studies, of which 22 were randomized controlled trials. The reviewed CR interventions primarily targeted physical activity counseling (31/31, 100%), baseline assessment (30/31, 97%), and exercise training (27/31, 87%). The most commonly used modalities were smartphones or mobile devices (20/31, 65%), web-based portals (18/31, 58%), and email-SMS (11/31, 35%). Approximately one-third of the studies addressed the CR core components of nutrition counseling, psychological management, and weight management. In contrast, less than a third of the studies addressed other CR core components, including the management of lipids, diabetes, smoking cessation, and blood pressure. CONCLUSIONS: Digital technologies have the potential to increase access and participation in CR by mitigating the challenges associated with traditional, facility-based CR. However, previously evaluated interventions primarily focused on physical activity counseling and exercise training. Thus, further research is required with more comprehensive CR interventions and long-term follow-up to understand the clinical impact of digital interventions.

BACKGROUND: Supervised exercise therapy (SET) is recommended in patients with symptomatic peripheral arterial disease (PAD) as first-line therapy, although patient adoption remains low. Home-based exercise therapy (HBET) delivered through smartphones may expand access. The feasibility of such programs, especially in low-resource settings, remains unknown. METHODS: Smart Step is a pilot randomized trial of smartphone-enabled HBET vs walking advice in patients with symptomatic PAD in an inner-city hospital. Participants receive a smartphone app with daily exercise reminders and educational content. A trained coach performs weekly phone-based coaching sessions. All participants receive a Fitbit Charge HR 2 to measure physical activity. The primary outcome changes in 6-minute walking test (6MWT) distance at 12 weeks over baseline. Secondary outcomes are the degree of engagement with the smartphone app and changes in health behaviors and quality of life scores after 12 weeks and 1 year. RESULTS: A total of 15 patients are randomized as of December 15, 2019 with a mean (SD) age of 66.1 (5.8) years. The majority are female (60%) and black (87%). At baseline, the mean (SD) ABI and 6MWT were 0.86 (0.29) and 363.5 m, respectively. Enrollment is expected to continue until December 2020 to achieve a target size of 50 participants. CONCLUSIONS: The potential significance of this trial will be to provide preliminary evidence of a home-based, "mobile-first" approach for delivering a structured exercise rehabilitation program. Smartphone-enabled HBET can be potentially more accessible than center-based programs, and if proven effective, may have a potential widespread public health benefit.

The potential cardiovascular (CV) benefits of many trending foods and dietary patterns are still incompletely understood, and scientific inquiry continues to evolve. In the meantime, however, a number of controversial dietary patterns, foods, and nutrients have received significant media attention and are mired by "hype." This second review addresses some of the more recent popular foods and dietary patterns that are recommended for CV health to provide clinicians with current information for patient discussions in the clinical setting. Specifically, this paper delves into dairy products, added sugars, legumes, coffee, tea, alcoholic beverages, energy drinks, mushrooms, fermented foods, seaweed, plant and marine-derived omega-3-fatty acids, and vitamin B12.

Metabolic equivalents, or METs, are routinely employed as a guide to exercise training and activity prescription and to categorize cardiorespiratory fitness (CRF). There are, however, inherent limitations to the concept, as well as common misapplications. CRF and the patient's capacity for physical activity are often overestimated and underestimated, respectively. Moreover, frequently cited fitness thresholds associated with the highest and lowest mortality rates may be misleading, as these are influenced by several factors, including age and gender. The conventional assumption that 1 MET = 3.5 mL O2/kg/min has been challenged in numerous studies that indicate a significant overestimation of actual resting energy expenditure in some populations, including coronary patients, the morbidly obese, and individuals taking ß-blockers. These data have implications for classifying relative energy expenditure at submaximal and peak exercise. Heart rate may be used to approximate activity METs, resulting in a promising new fitness metric termed the "personal activity intelligence" or PAI score. Despite some limitations, the MET concept provides a useful method to quantitate CRF and define a repertoire of physical activities that are likely to be safe and therapeutic. In conclusion, for previously inactive adults, moderate-to-vigorous physical activity, which corresponds to ≥3 METs, may increase MET capacity and decrease the risk of future cardiac events.

PURPOSE: Secondary prevention risk factor goals have been established by the American Heart Association/American College of Cardiology, and the American Heart Association has further delineated ideal cardiovascular health metrics. We evaluated risk factor goal achievement during early-outpatient cardiac rehabilitation (CR) and temporal trends in risk factor control. METHODS: Patients completed assessments on entry into and exit from CR at 35 centers between 2000 and 2009 and were categorized into 3 cohorts: entire (N = 12 984), 2000-2004 (n = 5468), and 2005-2009 (n = 7516) cohorts. RESULTS: Improvements occurred in multiple risk factors during CR. For the entire cohort, the percentages of patients at goal at CR completion ranged from 95.5% for smoking to 21.9% for body mass index (BMI) of <25.0 kg/m. Compared with 2000-2004, the percentage of the 2005-2009 cohort at goal was higher (P < .001) for blood pressure, low-density lipoprotein cholesterol, and physical activity, lower (P = .005) for BMI, and not significantly different (P > .05) for fasting glucose and smoking. At CR completion, of those in the entire, 2000-2004, and 2005-2009 cohorts, 4.4%, 3.9%, and 4.8% (P = .219 vs 2000-2004), respectively, had all biomarkers at the goal for ideal cardiovascular health and, of those with atherosclerotic cardiovascular disease, 70.8%, 71.5%, and 70.3% (P = .165 vs 2000-2004), respectively, were receiving statins. CONCLUSIONS: The percentage of patients at goal at CR completion increased for some, but not all, risk factors during 2005-2009 versus 2000-2004. Despite the benefits of CR, risk factor profiles are often suboptimal after CR. There remains room for improvement in risk factor management during CR and a need for continued intervention thereafter.

We have developed, tested, and successfully implemented an affordable, evidence-based, technology-enabled, data-driven, outcomes-oriented, comprehensive lifestyle health coaching (LHC) program. The LHC program has been used primarily to provide services to employees of larger employers (ie, with at least 3000 employees) but has also been implemented in a variety of other settings, including hospitals, cardiac rehabilitation centers, physician practices, and as part of multicenter clinical trials. The program is delivered mainly using the telephone and Internet. Health coaches are guided by a Web-based participant management and tracking system. Lifestyle management interventions are based on several behavior change models and strategies, especially adult learning theory, social learning theory, the stages of change model, single concept learning theory, and motivational interviewing. The program is administered by nonphysician health professionals whose services are integrated with the care provided by participants' physicians. Outcomes data from published studies, including randomized clinical trials and independent third-party conducted research, have documented the clinical effectiveness of this evidence-based approach in terms of modification of multiple risk factors in healthy persons as well as those with certain common chronic diseases.
RESUMEN
Cardiovascular disease (CVD) continues to be a leading cause of death worldwide. Because regular physical activity (PA) independently decreases the risk of coronary heart disease (CHD) while also having a positive, dose-related impact on other cardiovascular (CV) risk factors, it has increasingly become a focus of CHD prevention. Current guidelines recommend 30â min of moderate-intensity PA 5â days a week, but exercise regimens remain underused. PA adherence can be fostered with a multilevel approach that involves active individual participation, physician counselling and health coaching, community involvement, and policy change, with incorporation of cardiac rehabilitation for patients requiring secondary prevention. Viewing exercise quantity as a vital sign, prescribing PA like a medication, and using technology, such as smartphone applications, encourage a global shift in focus from CVD treatment to prevention. Community-wide, home-based and internet-based prevention initiatives may also offer a developing pool of resources that can be tapped into to promote education and PA compliance. This review summarises the underlying rationale, current guidelines for and recommendations to cultivate a comprehensive focus in the endorsement of PA in the primary and secondary prevention of CHD.

Atherosclerotic cardiovascular disease (ASCVD) continues to increase annually in the United States along with its associated enormous costs. A multidisciplinary cardiac rehabilitation (CR) and risk reduction program is an essential component of ASCVD prevention and management. Despite the strong evidence for CR in the secondary prevention of ASCVD, it remains vastly underutilized due to significant barriers. The current model of CR delivery is unsustainable and needs significant improvement to provide cost-effective, patient-centered, comprehensive secondary ASCVD prevention.

OPINION STATEMENT: It is well appreciated in pharmacotherapy that all drugs belonging to the same class of agents are not necessarily equally safe or effective. Because of this so-called "class effect paradox," pharmaceutical companies must do extensive research to prove the safety and efficacy of a new drug before introducing it into the market, even if it belongs to a well-established class of medications. Like pharmaceutical agents, lifestyle management interventions can be organized into classes. This commentary examines the rationale for, and importance of, considering the class effect paradox when balancing the need for new and innovative lifestyle management programs with the need for evidence-based interventions with proven outcomes. In view of the fact that all lifestyle management programs within a specific broad intervention class do not necessarily result in clinical benefit, it is recommended that any new approach should not be widely implemented until it has been shown to be effective as evidenced by results of clinical studies published in peer-reviewed journals.
RESUMEN
Antidepressants might increase compliance with cardiovascular disease risk reduction interventions. However, antidepressants have been linked to deleterious metabolic effects. In the present multicenter study, we sought to determine whether patients who take antidepressants derive the expected benefits from cardiac rehabilitation in terms of improvements in multiple atherosclerotic risk factors. A cohort of 26,957 patients who had completed a baseline assessment before participating in an exercise-based cardiac rehabilitation program constituted the study population. The patients were stratified into 3 cohorts (i.e., nondepressed, depressed unmedicated, and depressed medicated) at baseline according to a self-reported history of depression and the current use of antidepressants. Risk factors were assessed at baseline and after â¼12 weeks of program participation. A self-reported history of depression was present at baseline in 5,172 patients (19.2%). Of these patients, 2,147 (41.5%) were taking antidepressants. Patients in the nondepressed cohort (49.4% completion) were more likely (p <0.001) to complete the exit assessment than patients in the depressed unmedicated (44.5% completion) or depressed medicated (43.5% completion) cohorts. Patients in all 3 cohorts who completed the exit assessment showed significant improvement in multiple risk factors. Moreover, the magnitude of improvement in blood pressure, serum lipids and lipoproteins, fasting glucose, weight, and body mass index was similar (p >0.05) in patients taking antidepressants and those who were not. In conclusion, our study is the first to show that antidepressants do not offset the average magnitude of improvement in multiple atherosclerotic risk factors that occurs with completion of a cardiac rehabilitation program.

The impact of secondary prevention initiatives on survival in higher-risk socioeconomically disadvantaged patients after acute myocardial infarction (AMI) may depend on behavioral adaptive responsiveness, uptake, and adherence to healthier lifestyles. From December 1999 to February 2003, 1,801 patients in Ontario, Canada were interviewed regarding their lifestyle behaviors at 30 days after their index AMI hospitalization. Data were obtained using self-reported surveys, medical chart abstraction, and administrative data linkage. Multivariate analyses were adjusted for baseline sociodemographic, cardiac risk severity, and co-morbid conditions. Socioeconomically disadvantaged patients had greater cardiac risk severity at baseline than did their wealthier better-educated counterparts. Compared with lower-income patients, patients with higher incomes were less likely to smoke (adjusted odds ratio [OR] for highest vs lowest income tertiles 0.36, 95% confidence interval [CI] 0.21 to 0.63, p <0.001), more likely to participate in exercise (adjusted OR 1.40, 95% CI 1.07 to 1.85, p = 0.02), and more likely to decrease or discontinue alcohol use (adjusted OR 1.64, 95% CI 1.16 to 2.34, p = 0.06). The relation between education and lifestyle behaviors was less pronounced for education than for income. After adjustment for baseline factors, patients who acknowledged participation in regular physical exercise at 1 month had a significantly lower long-term mortality than those who did not. In conclusion, socioeconomically disadvantaged patients were sicker at baseline and less behaviorally responsive to embarking on healthy lifestyle changes after AMI than were those of higher socioeconomic status.

Although national clinical guidelines promulgate therapeutic lifestyle changes (TLC) as a cornerstone in the management of prehypertension, there is a perceived ineffectiveness of TLC in the real world. In this study of 2,478 ethnically diverse (African Americans n = 448, Caucasians n = 1,881) men (n = 666) and women (n = 1,812) with prehypertension and no known atherosclerotic cardiovascular disease, diabetes mellitus, or chronic kidney disease, we evaluated the clinical effectiveness of TLC in normalizing blood pressure (BP) without antihypertensive medications. Subjects were evaluated at baseline and after an average of 6 months of participation in a community-based program of TLC. TLC included exercise training, nutrition, weight management, stress management, and smoking cessation interventions. Baseline BP (125 +/- 8/79 +/- 3 mm Hg) decreased by 6 +/- 12/3 +/- 3 mm Hg (p

Habitual physical activity reduces coronary heart disease events, but vigorous activity can also acutely and transiently increase the risk of sudden cardiac death and acute myocardial infarction in susceptible persons. This scientific statement discusses the potential cardiovascular complications of exercise, their pathological substrate, and their incidence and suggests strategies to reduce these complications. Exercise-associated acute cardiac events generally occur in individuals with structural cardiac disease. Hereditary or congenital cardiovascular abnormalities are predominantly responsible for cardiac events among young individuals, whereas atherosclerotic disease is primarily responsible for these events in adults. The absolute rate of exercise-related sudden cardiac death varies with the prevalence of disease in the study population. The incidence of both acute myocardial infarction and sudden death is greatest in the habitually least physically active individuals. No strategies have been adequately studied to evaluate their ability to reduce exercise-related acute cardiovascular events. Maintaining physical fitness through regular physical activity may help to reduce events because a disproportionate number of events occur in least physically active subjects performing unaccustomed physical activity. Other strategies, such as screening patients before participation in exercise, excluding high-risk patients from certain activities, promptly evaluating possible prodromal symptoms, training fitness personnel for emergencies, and encouraging patients to avoid high-risk activities, appear prudent but have not been systematically evaluated.

The purpose of this 20-week, open-label, randomized clinical trial was to evaluate the effect of rosuvastatin on fasting serum lipids and lipoproteins, high-sensitivity C-reactive protein (hs-CRP), and the glomerular filtration rate (GFR) in 91 patients with chronic kidney disease. Patients were randomized to rosuvastatin 10 mg/day (n = 48) or to no lipid-lowering treatment (n = 43) for 20 weeks. In contrast to patients not receiving rosuvastatin, patients receiving rosuvastatin tended to derive more favorable improvements from baseline values in low-density lipoprotein cholesterol (-43%, p <0.001, vs 7%, p = NS; p <0.001 for change with rosuvastatin treatment vs change with no antilipemic treatment), hs-CRP (-47%, p <0.001, vs 7%, p = NS; p <0.001 for change with rosuvastatin treatment vs change with no antilipemic treatment), and GFR (11%, p <0.05, vs 4%, p = NS; p = NS for change with rosuvastatin treatment vs change with no antilipemic treatment).

In this prospective study of 2,390 ethnically diverse men and women, we evaluated the clinical effectiveness of 12 weeks of participation in a community-based lifestyle management program in helping patients who had hypertension, hyperlipidemia, and/or impaired fasting glucose or diabetes mellitus achieve goal risk factor levels without using pharmacotherapeutic agents. Although further research is warranted, the findings clearly show that many patients who have conventional risk factors for coronary heart disease can achieve goal levels without medications within 12 weeks of initiating therapeutic lifestyle changes and refute the notion that intensive lifestyle intervention is not worth the effort.
