The beneficial effect of exercise training and exercise-based cardiac rehabilitation on symptom-free exercise capacity,cardiovascular and skeletal muscle function, quality of life, general healthy lifestyle, and reduction of depressive symptoms and psychosocial stress is nowadays well recognized. However, it remains largely obscure, which characteristics of physical activity (PA) and exercise training--frequency, intensity, time (duration), type (mode), and volume (dose: intensity x duration) of exercise--are the most effective. The present paper, therefore, will deal with these exercise characteristics in the management of individuals with cardiovascular disease, i.e. coronary artery disease and chronic heart failure patients, but also in patients with congenital or valvular heart disease. Based on the current literature, and if sufficient evidence is available, recommendations from the European Association on Cardiovascular Prevention and Rehabilitation are formulated regarding fr...

Adropin is a peptide hormone that acts as a stabilizing factor in body energy metabolism and may be a marker for cardiovascular disease (CVD). The serum adropin level has been shown to be positively correlated with the nitrite/nitrate level and adropin appears to provide a protective endothelial function. Adropin has been reported to play a protective role in heart failure and hypertension. The underlying mechanism may help to reduce obesity and insulin resistance, improve endothelial dysfunction, and modulate the activity of the nervous system. Adropin regulates the cardiac energy cycle through a series of reactions, such as insulin signaling, glucose, and fat oxidation. This regulation of the energy circuit may represent a source of an alternative therapy for obese diabetes. The objective of this review was to contribute to the literature by examining research of the expression, processing, biological function, and role of adropin in the prevention of CVD.

Epidemiological, clinical and laboratory studies have yielded definitive evidence that physical activity is able to reduce the morbidity and mortality of cardiovascular diseases and to improve physical fitness and quality of life. Moreover, physical activ- ity seems to be capable of significantly reducing the risk of developing other chronic diseases, such as obesity, osteoporosis, diabetes, some neoplasms and depression. For

Janus kinase (JAK) inhibitors, a novel class of targeted synthetic disease-modifying antirheumatic drugs (DMARDs), have shown their safety and efficacy in rheumatoid arthritis (RA) and are being intensively tested in other autoimmune and inflammatory disorders. Targeting several cytokines with a single small compound leads to blocking the physiological response of hundreds of genes, thereby providing the background to stabilize the immune response. Unfortunately, blocking many cytokines with a single drug may also bring some negative consequences. In this review, we focused on the activity of JAK inhibitors in the cardiovascular system of patients with RA. Special emphasis was put on the modification of heart performance, progression of atherosclerosis, lipid profile disturbance, and risk of thromboembolic complications. We also discussed potential pathophysiological mechanisms that may be responsible for such JAK inhibitor-associated side effects.

Previous studies have lacked sufficient power to assess associations between early-life socioeconomic position and adult cause-specific mortality. The authors examined associations of parental social class at age 0-16 years with mortality among 1,824,064 Swedes born in 1944-1960. Females and males from manual compared with nonmanual childhood social classes were more likely to die from smoking-related cancers, stomach cancer, respiratory disease, cardiovascular disease, and diabetes. Males from manual compared with nonmanual social classes were more likely to die from unintentional injury, homicide, and alcoholic cirrhosis. The association with stomach cancer was little affected by adjustment for parental later-life and own adult social class or education. For other outcomes, educational attainment resulted in greater attenuation of associations than did adjustment for adult social class. Early-life social class was not related to suicide or to melanoma, colon, breast, brain, or lym...

Three-dimensional (3D) printing technology has undergone rapid developments over the last decades. The application of 3D printing has reached beyond the engineering field to medicine, with research showing many applications in cardiovascular disease. Due to the complexity of the cardiovascular system, application of 3D printing technology has shown potential value to benefit patients with cardiovascular disease. This mini-review provides an overview of applications of 3D printing in cardiovascular disease, with evidence of some of examples using patient-specific 3D printed models in the two common cardiovascular diseases, aortic dissec-tion and abdominal aortic aneurysm.

Progression of Rheumatoid arthritis (RA) and osteoarthritis (OA) is associated with inflammation and oxidative stress. Previous studies have shown that there was no difference between RA and OA patients regarding the percentages of the different lymphocytes subsets reflecting the abnormalities in T cells and its subsets that may contribute to the pathogenesis of OA as in RA. Therefore, the present study was aimed to analyze that whether disease activity of OA is able to affect a few serological and biochemical parameters in the same way as RA does or differently. The study was done on 36 asymptomatic controls (25 women), 28 patients with OA (20 women), 36 patients with RA (22 women). Patients with OA were screened according to radiological and clinical finding of Kellgren and Lawrence grade and ACR criteria and assessed by VAS and WOMAC score. Patients with RA were selected who were fulfilling 4/5 symptoms of ACR criteria, and their DAS28-CRP, VAS score, and RF positivity were evaluated. Participants of the groups were matched for sex, age, weight, and height (body mass index). The BMI of all three groups was also found to be the same (P > 0.05). The mean level of LDL, Cholesterol, MDA, CRP, and Triglyceride was significantly (P < 0.05 or P < 0.01) higher in both OA and RA as compared to control. The mean level of total lipid, cholesterol, MDA, CRP, and triglyceride was found to be significantly (P < 0.05 or P < 0.01) higher in RA as compared to OA. The pre-treatment CRP level of both groups of patients showed significant and direct relation with total lipid (r = 0.27, P < 0.05) and cholesterol (r = 0.66, P < 0.01). Inverse relation was observed between Uric acid and Creatinine (r = −0.26, P < 0.05) and cholesterol and HDL (r = −0.34, P < 0.01). Our study shows the similar trend in lipid profile and other parameters studied in both patients with OA and patients with RA with more pronounced changes in RA.

Cardiovascular disease is a major cause of death and thus a great deal of effort has been made in salvaging the diseased myocardium. Although various factors have been identified as possible causes of different cardiac diseases such as heart failure and ischemic heart disease, there is a real need to elucidate their role for the better understanding of the cardiac disease pathology and formulation of strategies for developing newer therapeutic interventions. In view of the intimate involvement of different types of proteases in maintaining cellular structure, the role of proteases in various cardiac diseases has become the focus of recent research. Proteases are present in the cytosol as well as are localized in a number of subcellular organelles in the cell. These are known to use extracellular matrix, cytoskeletal, sarcolemmal, sarcoplasmic reticular, mitochondrial and myofibrillar proteins as substrates. Work from different laboratories using a wide variety of techniques has shown that the activation of proteases causes alterations of a number of specific proteins leading to subcellular remodeling and cardiac dysfunction. Inhibition of protease action by different drugs and agents, therefore, has a clinical relevance and is expected to form a part of new treatment paradigm for improving heart function. This review examines the biochemistry and localization of some of the proteases in the cardiac tissue in addition to identification of the sites of action of some protease inhibitors.

The objective of this study was to predict the prevalence of type 2 diabetes and the associated burden to the health care system in Greenland posed by diabetic complications by 2014. The predictions were based on changes in demographic variables and obesity. Projection model based on two cross-sectional population surveys from 1993 and 1999. The development in BMI was described and projected to 2014 under two assumptions: 1) distribution of BMI is constant from 1999, and 2) the trend in BMI found in the surveys will continue until 2014. The prevalence of type 2 diabetes was predicted under these assumptions and based on the observed association between BMI and type 2 diabetes. The prevalence of complications was estimated using the 2nd assumption, as was the prevalence of hypertension, dyslipidemia, Ischemic Heart Disease (IHD) and stroke in the non-diabetic population in 2014. The prevalence of type 2 diabetes was not predicted to increase by 2014 under the 1st assumption. It was p...

Objectives: The goal of this study was to compare cost-effectiveness of sacubitril/valsartan with angiotensin-converting enzyme (ACE) inhibitors for treating chronic heart failure patients with reduced ejection fraction (HFrEF) from the published articles and explore the methodology applied in the studies.
Methods: Systematic research was conducted in February 2021 using PubMed, Cochrane, and EBSCO. A combination of MeSH terms of ‘cost-effectiveness analysis’, ‘heart failure with reduced ejection fraction’, ‘sacubitril valsartan’ and ‘angiotensin converting enzyme inhibitor’ was employed. The review selected for articles published in the last five years in English.
Results: A total of 15 studies were included in this review. We found that the studies had been conducted in 12 different countries. The United States had the greatest number of publications (5), followed by the Netherlands (2). The study method most used was the Markov decision model (73%). Almost all studies produced ICERs and QALYs that were numerically high.
Conclusions: The use of sacubitril/valsartan associates with longer life expectancy and incremental cost-effectiveness ratio than angiotensin-converting enzyme inhibitors.

Background— Population-based genome-wide association studies have identified several single nucleotide polymorphisms (SNPs) associated with cardiovascular disease or its risk factors. Genes in close proximity to these risk-SNPs are often thought to be pathogenetically important based on their location alone. However, the actual connections between SNPs and disease mechanisms remain largely unknown. Methods and Results— To identify novel susceptibility genes, we investigated how 166 SNPs previously found to be associated with increased cardiovascular risk and/or predisposing metabolic traits relate to the expression of nearby genes. Gene expression in 577 samples of aorta, liver, mammary artery, and carotid atherosclerotic plaque was measured using expression arrays. For 47 SNPs, the expression levels of proximal genes (located within 200 kb) were affected ( P <0.005). More than 20 of these genes had not previously been identified as candidate genes for cardiovascular or related m...

Venous thromboembolism (VTE) is a significant cause of mortality in patients with lung cancer. Despite the availability of a wide range of anticoagulants to help prevent thrombosis, thromboprophylaxis in ambulatory patients is a challenge due to its associated risk of haemorrhage. As a result, anticoagulation is only recommended in patients with a relatively high risk of VTE. Efforts have been made to develop predictive models for VTE risk assessment in cancer patients, but the availability of a reliable predictive model for ambulate patients with lung cancer is unclear. We have analysed the latest information on this topic, with a focus on the lung cancer-related risk factors for VTE, and risk prediction models developed and validated in this group of patients. The existing risk models, such as the Khorana score, the PROTECHT score and the CONKO score, have shown poor performance in external validations, failing to identify many high-risk individuals. Some of the newly developed an...

Variation in human lifespan is 20 to 30% heritable but few genetic variants have been identified. We undertook a Genome Wide Association Study (GWAS) using age at death of parents of middle-aged UK Biobank participants of European decent (n=75,244 with father's and/or mother's data). Genetic risk scores for 19 phenotypes (n=777 proven variants) were also tested. Genotyped variants (n=845,997) explained 10.2% (SD=1.3%) of combined parental longevity. In GWAS, a locus in the nicotine receptor CHRNA3 - previously associated with increased smoking and lung cancer - was associated with paternal age at death, with each protective allele (rs1051730[G]) being associated with 0.03 years later age at father's death (p=3x10-8). Offspring of longer lived parents had more protective alleles (lower genetic risk scores) for coronary artery disease, systolic blood pressure, body mass index, cholesterol and triglyceride levels, type-1 diabetes, inflammatory bowel disease and Alzheimer&#3...

Background: Cardiovascular disease is the leading cause of death in the all regions of India, with the highest proportion in the Southern region (25%) and the lowest in the Central region (12%). People diagnosed with coronary heart disease (CHD) are at an increased risk for illness and death. Lifestyle related behavioural risk factors are mainly implicated for increased burden of cardiovascular diseases. To reduce this risk, it is recommended that people who are diagnosed with CHD improve their health behaviors. The objective of this study was to assess the prevalence of associated lifestyle risk behaviors such as diet, physical activity, sedentary lifestyle, stress and CVD.

During the past 35 years Oman has undergone a rapid socioeconomic and epidemiological transition leading to a steep reduction in child and adult mortality and morbidity due to the decline of various communicable diseases, including vaccine-preventable diseases. Good governance and planning, together with leadership and commitment by the government, has been a critical factor in this reduction. However, with increasing prosperity, lifestyle-related noncommunicable diseases have emerged as new health challenges to the country, with cardiovascular diseases, diabetes and obesity in the lead among other chronic conditions. Appropriate prevention strategies for reducing the burden of noncommunicable diseases are discussed.

Summary: Cardiovascular diseases are often accompanied by mental health problems and depression. To improve the quality of life of patients with cardiac disease it's necessary to include psychosocial care as part of the comprehensive... more

Purpose of review Rapid eye movement (REM) obstructive sleep apnoea (OSA) is a stage-specific OSA, in which obstructive events occur primarily during REM sleep. This review discusses REM-OSA definitions, its cardiometabolic correlates, associated comorbidities and treatment, and addresses diagnostic ambiguities and therapeutic pitfalls. Recent findings Current evidence indicates that REM-OSA is prevalent among younger age groups and women and is independently associated with cardiometabolic complications, particularly hypertension, metabolic complications such as insulin resistance and metabolic syndrome. However, currently, there is no consensus on the accepted diagnostic criteria for REM-OSA. Available data suggest that adherence to positive airway pressure (PAP) therapy in patients with REM-OSA is suboptimal. Moreover, the currently accepted criteria for good adherence to PAP therapy of 4 h/night, 70% of the days may not be suitable for REM-OSA, as it will not cover most of the REM sleep periods. In addition, further research is needed to assess the impact of REM-OSA treatment on cardiometabolic outcomes. Summary Patients with REM-OSA are at an increased risk of cardiometabolic complications. A high index of suspicion is needed to diagnose this disorder, and close follow-up is required to enhance adherence to therapy.
