"Plain wrong" — this is what a new science editorial says of a widely believed idea that saturated fats clog up one’s arteries and result in coronary heart disease. Now the piece has stirred controversy among experts in the field and revived the longstanding clash over saturated fats and how they affect one’s health. “Despite popular belief among doctors and the public, the conceptual model of dietary saturated fat clogging a pipe is just plain wrong,” wrote a team of three cardiologists in the British Journal of Sports Medicine. Standard medical advice maintains that saturated fats affect the blood cholesterol, the wax-like substance that can accumulate in one’s arteries. There are different types of cholesterol, from “good” or high-density lipoprotein (HDL) to “bad” or low-density lipoprotein (LDL). LDL cholesterol is believed to build up and lead to heart disease with too much saturated fat in one’s diet, or the animal-based fats found in pork, beef, chicken, cheese, butter, and other foods. According to the authors citing a meta-analysis or review of previous studies, eating these fats is not linked to coronary heart disease, ischemic stroke, type 2 diabetes, or heart disease death in healthy individuals. They dubbed it “misguided” to keep focusing on lowering plasma cholesterol “as if this was an end in itself,” as well as an emphasis on “low fat” diets and medications. Lead author Dr. Aseem Malhotra is a British cardiologist known in their local media to promote high-fat diets. His other report from last year was also controversial in its recommendation going against conventional advice. He and his coauthors noted to CNN that healthy people can reduce their coronary disease risk effectively by walking 22 minutes every day, managing their stress, and consuming “real food.” Critics of the new editorial, however, were quick to point out that meta-analyses are based on observational data, which aren’t deemed conclusive based on general standards and hardly establish causation. For Garry Jennings, cardiologist and chief medical advisor of the National Heart Foundation of Australia, the editorial is rife with “a mixture of truths, half-truths, and misconceptions,” pointing out a couple of “poor and discredited” research quoted to buoy the argument. Those with high LDL cholesterol suffer more heart attacks, and leaving LDL cholesterol out of the picture misleads readers, Jennings explained. Dr. Mike Knapton, the British Heart Foundation’s associate medical director, also called the opinion piece “misleading” in light of decades of studies proving that a saturated fat-rich diet raises “bad cholesterol” and puts one at a greater heart disease or stroke risk. According to the American Heart Association, a stroke or heart attack can start when plaque from cholesterol or fat builds up in the arteries and effectively “hardens” them. This is known as atherosclerosis, and in this scenario, either a blood clot forms or a portion of the plaque breaks off and blocks the artery. The editorial pointed to the importance of regular light exercise as well as the Mediterranean diet, which is high in so-called healthy fat such as nuts and olives. A recent study lauded this diet for a potentially lower rate of diagnosis of ADHD in children and adolescents. © 2017 Tech Times, All rights reserved. Do not reproduce without permission.

Aim: To compare the reported content of key nutrients related to cardiovascular health (energy, total fat, saturated fat and sodium) between Private Label and Branded products for various food categories in Australian supermarkets, using Nutrition Information Panel data. Reported serve size was also assessed. Methods: A cross-sectional study using selected Nutrition Information Panel data collected during 2006-2008 for 25 food categories, across 10 Australian supermarkets. Collected data included serve size and nutrients per 100g: energy, total fat, saturated fat and sodium. Differences between Private Label versus Branded products were assessed using independent samples t-test. Results: Data were collected for 3204 products; Private Label products accounted for 26% (n = 824). Serve size was significantly different between Private Label and Branded for seven categories. Total and saturated fat for Private Label products was significantly greater (than Branded) for five and seven categories, respectively. Sodium was significantly different between Private Label and Branded for seven categories, with no consistency in direction. Conclusion: Differences between Branded and Private Label products were food category specific. The present study provides a first-time comparison of a comprehensive sample of Branded versus Private Label products, across multiple food categories, in Australia with respect to nutrients related to cardiovascular health. It also provides insight into serve size differences, and may be used as a baseline for future comparisons of nutritional content and serve sizes between Branded and Private Label products, and to monitor the impact of potential new food product developments and reformulations. © 2011 The Authors.

Background: The National Heart Foundation of Australia (NHFA) 2008 review on omega-3 long-chain polyunsaturated fatty acids (LCPUFA) made recommendations with respect to supplementation for primary and secondary prevention of cardiovascular disease. Since then, new findings have been published regarding the relationship between omega-3 polyunsaturated fatty acids, including supplementation, and cardiovascular health. Methods: A literature search was undertaken in PubMed and Medline, for literature published between January 1, 2007 and August 31, 2013. Results and Conclusions: A total of eight research questions were developed and, using the National Health and Medical Research Council's evidence assessment framework, conclusions were made in relation to dietary intake of fish and omega-3 LCPUFA for cardiovascular health. In the evidence published since 2007, this summary of evidence concludes that dietary intake of fish was found to be mostly consistent with respect to protection from heart disease and stroke. Higher fish intake was associated with lower incident rates of heart failure in addition to lower sudden cardiac death, stroke and myocardial infarction. In relation to omega-3 LCPUFA supplementation, neither a beneficial nor adverse effect was demonstrated in primary or secondary prevention of coronary heart disease (CHD). Although the evidence continues to be positive for the role of omega-3 LCPUFA in the treatment of hypertriglyceridaemia and a modest positive benefit in heart failure. No further evidence was found to support the consumption of 2. g alpha-linolenic acid (ALA)/day over the current Australian guidelines for 1. g/day. © 2015 Australian and New Zealand Society of Cardiac and Thoracic Surgeons (ANZSCTS) and the Cardiac Society of Australia and New Zealand (CSANZ).

Background: The smoking epidemic in Australia is characterised by historic levels of prolonged smoking, heavy smoking, very high levels of long-term cessation, and low current smoking prevalence, with 13% of adults reporting that they smoked daily in 2013. Large-scale quantitative evidence on the relationship of tobacco smoking to mortality in Australia is not available despite the potential to provide independent international evidence about the contemporary risks of smoking. Methods: This is a prospective study of 204,953 individuals aged ≥45years sampled from the general population of New South Wales, Australia, who joined the 45 and Up Study from 2006-2009, with linked questionnaire, hospitalisation, and mortality data to mid-2012 and with no history of cancer (other than melanoma and non-melanoma skin cancer), heart disease, stroke, or thrombosis. Hazard ratios (described here as relative risks, RRs) for all-cause mortality among current and past smokers compared to never-smokers were estimated, adjusting for age, education, income, region of residence, alcohol, and body mass index. Results: Overall, 5,593 deaths accrued during follow-up (874,120 person-years; mean: 4.26years); 7.7% of participants were current smokers and 34.1% past smokers at baseline. Compared to never-smokers, the adjusted RR (95% CI) of mortality was 2.96 (2.69-3.25) in current smokers and was similar in men (2.82 (2.49-3.19)) and women (3.08 (2.63-3.60)) and according to birth cohort. Mortality RRs increased with increasing smoking intensity, with around two- and four-fold increases in mortality in current smokers of ≤14 (mean 10/day) and ≥25 cigarettes/day, respectively, compared to never-smokers. Among past smokers, mortality diminished gradually with increasing time since cessation and did not differ significantly from never-smokers in those quitting prior to age 45. Current smokers are estimated to die an average of 10years earlier than non-smokers. Conclusions: In Australia, up to two-thirds of deaths in current smokers can be attributed to smoking. Cessation reduces mortality compared with continuing to smoke, with cessation earlier in life resulting in greater reductions. © 2015 Banks et al.

Journal of Hypertension | Year: 2012
Objective: Although most national guidelines for the diagnosis and management of hypertension emphasize that the initiation and modification of blood pressure (BP)-lowering treatment should be related to absolute cardiovascular disease (CVD) risk, there is only limited information on how to incorporate ambulatory BP (ABP) monitoring into this framework. The objective of this initiative is to provide ABP equivalents for BP cut-points for treatment initiation and targets to be included into guidelines. Methods: A critical analysis of the best available evidence from clinical trials and observational studies was undertaken to develop a new consensus statement for ABP monitoring. Results: ABP monitoring has an important place in defining abnormal patterns of BP, particularly white-coat hypertension (including in pregnancy), episodic hypertension, masked hypertension, labile BP and nocturnal or morning hypertension. This consensus statement provides a framework for appropriate inclusion of ABP equivalents for low, moderate and high CVD risk patients. The wider use of ABP monitoring, although justified, is limited by its availability and cost due to the lack of medical subsidy in Australia. However, cost-benefit analysis does suggest a cost-saving in reduced numbers of inappropriate antihypertensive treatments. Conclusion: Although clinic measurement of BP will continue to be useful for screening and management of suspected and true hypertension, ABP monitoring provides considerable added value toward accurate diagnosis and the provision of optimal care in uncomplicated hypertension, as well as for patients with moderate or severe CVD risk. © 2012 Wolters Kluwer Health | Lippincott Williams & Wilkins.

The traditional hospital-based model of cardiac rehabilitation faces substantial challenges, such as cost and accessibility. These challenges have led to the development of alternative models of cardiac rehabilitation in recent years. The aim of this study was to identify and critique evidence for the effectiveness of these alternative models. A total of 22 databases were searched to identify quantitative studies or systematic reviews of quantitative studies regarding the effectiveness of alternative models of cardiac rehabilitation. Included studies were appraised using a Critical Appraisal Skills Programme tool and the National Health and Medical Research Council's designations for Level of Evidence. The 83 included articles described interventions in the following broad categories of alternative models of care: multifactorial individualized telehealth, internet based, telehealth focused on exercise, telehealth focused on recovery, community- or homebased, and complementary therapies. Multifactorial individualized telehealth and community- or home-based cardiac rehabilitation are effective alternative models of cardiac rehabilitation, as they have produced similar reductions in cardiovascular disease risk factors compared with hospital-based programmes. While further research is required to address the paucity of data available regarding the effectiveness of alternative models of cardiac rehabilitation in rural, remote, and culturally and linguistically diverse populations, our review indicates there is no need to rely on hospital-based strategies alone to deliver effective cardiac rehabilitation. Local healthcare systems should strive to integrate alternative models of cardiac rehabilitation, such as brief telehealth interventions tailored to individual's risk factor profiles as well as community- or home-based programmes, in order to ensure there are choices available for patients that best fit their needs, risk factor profile, and preferences. © The European Society of Cardiology 2013.

Considerable evidence has associated increasing portion sizes with elevated obesity prevalence. This study examines typical portion sizes of commonly consumed core and discretionary foods in Australian adults, and compares these data with the Australian Dietary Guidelines standard serves. Typical portion sizes are defined as the median amount of foods consumed per eating occasion. Sex- and age-specific median portion sizes of adults aged 19 years and over (n = 9341) were analysed using one day 24 hour recall data from the 2011-12 National Nutrition and Physical Activity Survey. A total of 152 food categories were examined. There were significant sex and age differences in typical portion sizes among a large proportion of food categories studied. Typical portion sizes of breads and cereals, meat and chicken cuts, and starchy vegetables were 30-160% larger than the standard serves, whereas, the portion sizes of dairy products, some fruits, and non-starchy vegetables were 30-90% smaller. Typical portion sizes for discretionary foods such as cakes, ice-cream, sausages, hamburgers, pizza, and alcoholic drinks exceeded the standard serves by 40-400%. The findings of the present study are particularly relevant for establishing Australian-specific reference portions for dietary assessment tools, refinement of nutrition labelling and public health policies.

Cardiovascular disease (CVD) is a leading cause of morbidity and mortality in Australia. Australian Aboriginal and Torres Strait Islander (Indigenous) people have higher levels of CVD compared with non-Indigenous people. Cardiac Rehabilitation (CR) is an evidence-based intervention that can assist with reducing subsequent cardiovascular events and rehospitalisation. Unfortunately, attendance rates at traditional CR programs, both globally and in Australia, are estimated to be as low as 10-30% and Indigenous people are known to be particularly under-represented. An in-depth assessment was undertaken to investigate the provision of CR and secondary preveniton services in Western Australia (WA) with a focus on rural, remote and Indigenous populations. This paper reports on the findings for Indigenous people.Cardiac rehabilitation and Aboriginal Medical Services (n=38) were identified for interview through the Heart Foundation Directory of Western Australian Cardiac Rehabilitation and Secondary Prevention Services 2012. Semi-structured interviews with CR coordinators were conducted and included questions specific to Indigenous people.Interviews with coordinators from 34 CR services (10 rural, 12 remote, 12 metropolitan) were conducted. Identification of Indigenous status was reported by 65% of coordinators; referral and attendance rates of Indigenous patients differed greatly across WA. Efforts to meet the cultural needs of Indigenous patients varied and included case management (32%), specific educational materials (35%), use of a buddy or mentoring system (27%), and access to an Aboriginal Health Worker (71%). Staff cultural awareness training was available for 97% and CR guidelines were utilised by 77% of services.The under-representation of Indigenous Australians participating in CR, as reported in the literature and more specifically in this study, mandates a concerted effort to improve services to better meet the needs of Indigenous patients with CVD as part of closing the gap in life expectancy. Improving access to culturally appropriate CR and secondary prevention in WA must be an important component of this effort given the high rates of premature cardiovascular disease affecting Indigenous people. Our findings also highlight the importance of good systematic data collection across services. Health pathways that ensure continuity of care and alternative methods of CR delivery with dedicated resources are needed.

Aboriginal and Torres Strait Islander patients with acute coronary syndromes (ACS) experience lower intervention rates and poorer outcomes compared with non-Indigenous patients. A broad range of geographical, cultural and systemic factors contribute to delays and suboptimal treatment for ACS. Every Indigenous ACS patient, regardless of where they live, should be able to expect a coordinated, patientcentred pathway of care provided by designated provider clinical networks and supported by Indigenous cardiac coordinators, Aboriginal liaison offi cers (ALOs) and health workers. These designated provider clinical networks provide: ▶ appropriate prehospital and inhospital treatment ▶ an individualised patient care plan developed jointly with the patient and his or her family ▶ culturally appropriate education initiated within the hospital setting and involving families with support from ALOs ▶ eff ective follow-up care and access to relevant secondary prevention programs. We outline generic pathways to provide policymakers, health planners and health care providers with a framework for ACS diagnosis and management that can be implemented across the diverse settings in which Aboriginal and Torres Strait Islander people reside and their care is delivered, in order to optimise care and assertively address the current disparities in outcomes.
