Abstract
OBJECTIVE The development of these guidelines is mandated by the American Association of Clinical Endocrinologists (AACE) Board of Directors and American College of Endocrinology (ACE) Board of Trustees and adheres with published AACE protocols for the standardized production of clinical practice guidelines (CPGs). METHODS Recommendations are based on diligent reviews of the clinical evidence with transparent incorporation of subjective factors, according to established AACE/ACE guidelines for guidelines protocols. RESULTS The Executive Summary of this document contains 87 recommendations of which 45 are Grade A (51.7%), 18 are Grade B (20.7%), 15 are Grade C (17.2%), and 9 (10.3%) are Grade D. These detailed, evidence-based recommendations allow for nuance-based clinical decision-making that addresses multiple aspects of real-world medical care. The evidence base presented in the subsequent Appendix provides relevant supporting information for Executive Summary Recommendations. This update contains 695 citations of which 203 (29.2 %) are EL 1 (strong), 137 (19.7%) are EL 2 (intermediate), 119 (17.1%) are EL 3 (weak), and 236 (34.0%) are EL 4 (no clinical evidence). CONCLUSION This CPG is a practical tool that endocrinologists, other health care professionals, health-related organizations, and regulatory bodies can use to reduce the risks and consequences of dyslipidemia. It provides guidance on screening, risk assessment, and treatment recommendations for a range of individuals with various lipid disorders. The recommendations emphasize the importance of treating low-density lipoprotein cholesterol (LDL-C) in some individuals to lower goals than previously endorsed and support the measurement of coronary artery calcium scores and inflammatory markers to help stratify risk. Special consideration is given to individuals with diabetes, familial hypercholesterolemia, women, and youth with dyslipidemia. Both clinical and cost-effectiveness data are provided to support treatment decisions.

The effectiveness and cost-effectiveness of plant sterol or stanol-enriched functional foods as a primary prevention strategy for people with cardiovascular disease risk in England: a modeling study. THE EUROPEAN JOURNAL OF HEALTH ECONOMICS : HEPAC : HEALTH ECONOMICS IN PREVENTION AND CARE 2018; 19:909-922. [PMID: 29110223 PMCID: PMC6105215 DOI: 10.1007/s10198-017-0934-2] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/14/2016] [Accepted: 10/04/2017] [Indexed: 05/08/2023]
Abstract
This study appraises the effectiveness and cost-effectiveness of consumption of plant sterol-enriched margarine-type spreads for the prevention of cardiovascular disease (CVD) in people with hypercholesterolemia in England, compared to a normal diet. A nested Markov model was employed using the perspective of the British National Health Service (NHS). Effectiveness outcomes were the 10-year CVD risk of individuals with mild (4-6 mmol/l) and high (above 6 mmol/l) cholesterol by gender and age groups (45-54, 55-64, 65-74, 75-85 years); CVD events avoided and QALY gains over 20 years. This study found that daily consumption of enriched spread reduces CVD risks more for men and older age groups. Assuming 50% compliance, 69 CVD events per 10,000 men and 40 CVD events per 10,000 women would be saved over 20 years. If the NHS pays the excess cost of enriched spreads, for the high-cholesterol group, the probability of enriched spreads being cost-effective is 100% for men aged over 64 years and women over 74, at £20,000/QALY threshold. Probabilities of cost-effectiveness are lower at younger ages, with mildly elevated cholesterol and over a 10-year time horizon. If consumers bear the full cost of enriched spreads, NHS savings arise from reduced CVD events.

Abstract
OBJECTIVE To estimate the cost-effectiveness of statin therapy for primary prevention of coronary heart disease (CHD) events under real-world adherence. METHODS A cost-effectiveness model was applied to estimate the expected 10-year costs and health outcomes (in terms of quality-adjusted life-years, QALYs) associated with and without statin treatment (at defined adherence levels) among hypothetical cohorts of Finnish men and women who were initially without established CHD. Treatment efficacy, cost, and quality of life estimates were obtained from published sources. Long-term treatment adherence was measured based on data from the national prescription register. RESULTS At an assumed willingness-to-pay threshold of €20,000 per QALY gained, statin treatment with real-world adherence was cost-effective among the older patient groups when the patients' 10-year CHD risk was as high as 20% and did not seem cost-effective in the youngest age groups. Conversely, statin treatment with full adherence was cost-effective for almost all patient groups with a 10-year CHD risk of at least 15%. CONCLUSIONS Even though generic statins are now low-cost drugs, treatment adherence seems to have a major impact on the cost-effectiveness of statin treatment in primary prevention. This finding stresses the importance of making a concerted effort for improving adherence among patients on statin therapy to obtain full benefit of the investment in statins. Therefore, novel cost-effective approaches to improve treatment adherence are warranted.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Terminalia arjuna (Roxb.) Wight & Arn. is one of the most popular and beneficial medicinal plants in indigenous system of medicine for the treatment of cardiovascular diseases. This comprehensive review provides latest updates on traditional use, phytochemistry, pharmacological and toxicological data, clinical efficacy and safety of Terminalia arjuna as well as outlined strategies for future research and development to scientifically validate the therapeutic potential of this plant. MATERIALS AND METHODS Information about Terminalia arjuna was collected via a systematic electronic and library search of various indexed and non-indexed journals, some local books and varied articles published on ethnopharmacology, phytochemistry and traditional uses. Various pre-clinical (2000-2014) and clinical studies (1990-2014) have also been considered regarding efficacy and safety profile of Terminalia arjuna. RESULTS Evidence from various in vitro, in vivo and clinical trials reveal the pleiotropic effects of Terminalia arjuna such as anti-atherogenic, hypotensive, inotropic, anti-inflammatory, anti-thrombotic and antioxidant actions for treatment of various cardiovascular disorders. It is clearly documented that this plant has a good safety profile when used in conjunction with other conventional drugs. However, there is a paucity of data regarding the exact molecular mechanism of its action, appropriate form of drug administration, whether whole crude drug or aqueous or alcoholic extract should be used, toxicological studies and its interaction with other drugs. CONCLUSIONS In conclusion, this review highlights the importance as well as pleiotropic actions and functional aspects of Terminalia arjuna especially in cardiovascular diseases. Though, various pharmacological studies and clinical trials support its benefit in the CVD as per traditional use, new clinical trials using more rigorous state of the art technology and in a larger population setup are warranted to assess the traditional putative efficacy of Terminalia arjuna.

Abstract
Concern about the overconsumption of unhealthy foods is growing worldwide. With high global rates of noncommunicable diseases related to poor nutrition and projections of more rapid increases of rates in low- and middle-income countries, it is vital to identify effective but low-cost interventions. Cost-effectiveness studies show that individually targeted dietary interventions can be effective and cost-effective, but a growing number of modeling studies suggest that population-wide approaches may bring larger and more sustained benefits for population health at a lower cost to society. Mandatory regulation of salt in processed foods, in particular, is highly recommended. Future research should focus on lacunae in the current evidence base: effectiveness of interventions addressing the marketing, availability, and price of healthy and unhealthy foods; modeling health impacts of complex dietary changes and multi-intervention strategies; and modeling health implications in diverse subpopulations to identify interventions that will most efficiently and effectively reduce health inequalities.

Abstract
Elevated serum lipids are linked to cardiovascular diseases calling for effective therapeutic means to reduce particularly LDL-cholesterol (LDL-C) levels. Plant stanols reduce levels of LDL-C by partly blocking cholesterol absorption. Accordingly the consumption of foods with added plant stanols, typically esterified with vegetable oil fatty acids in commercial food products, are recommended for lowering serum cholesterol levels. A daily intake of 1.5 to 2.4 g of plant stanols has been scientifically evaluated to lower LDL-C by 7 to 10% in different populations, ages and with different diseases. Based on earlier studies, a general understanding is that no further reduction may be achieved in intakes in excess of approximately 2.5 g/day. Recent studies however suggest that plant stanols show a continuous dose–response effect in serum LDL-C lowering. This review discusses the evidence for a dose-effect relationship between plant stanol ester consumption and reduction of LDL-C concentrations with daily intakes of plant stanols of 4 g/day or more. We identified five such studies and the overall data demonstrate a linear dose-effect relationship with the most pertinent LDL-Cholesterol lowering outcome, 18%, achieved by a daily intake of 9 to 10 g of plant stanols. Along with reduction in LDL-C, the studies demonstrated a decrease in cholesterol absorption markers, the serum plant sterol to cholesterol ratios, by increasing the dose of plant stanol intake. None of the studies with daily intakes up to 10 g of plant stanols reported adverse clinical or biochemical effects from plant stanols. In a like manner, the magnitude of decrease in serum antioxidant vitamins was not related to the dose of plant stanols consumed and the differences between plant stanol ester consumers and controls were minor and insignificant or nonexisting. Consumption of plant stanols in high doses is feasible as a range of food products are commercially available for consumption including spreads and yoghurt type drinks. In conclusion, a dose-effect relationship of plant stanols in higher doses than currently recommended has been demonstrated by recent clinical studies and a meta-analysis. Further studies are called for to provide confirmatory evidence amenable for new health claim applications and dietary recommendations.

Abstract
BACKGROUND/OBJECTIVES To predict the health economic consequences of modest reductions in the daily intake of salt (-1.0 g per day) and replacement of saturated fat (SFA, -1.0 energy percent (E%)) with polyunsaturated fat (PUFA, +1.0 E%) in the Finnish population aged 30-74 years. SUBJECTS/METHODS A Markov model with dynamic population structure was constructed to present the natural history of cardiovascular diseases (CVDs) based on the most current information about the age- and sex-specific cardiovascular risk factors, dietary habits and nutrient intake. To predict the undiscounted future health economic consequences of the reduction of dietary salt and SFA, the model results were extrapolated for the years 2010-2030 by replacing the baseline population in the year 2007 with the extrapolated populations from the official Finnish statistics. Finnish costs (€2009, societal perspective) and EQ-5D utilities were obtained from published references. RESULTS During the next 20 years, a population-wide intervention directed at salt intake and dietary fat quality could potentially lead to 8000-13,000 prevented CVD cases among the Finnish adults compared the situation in year 2007. In addition, the reduced incidence of CVDs could gain 26,000-45,000 quality-adjusted life years and save €150-225 million over the same time period. CONCLUSION A modest reduction of salt and replacement of SFA with PUFA in food products can significantly reduce the burden of CVD in the adult Finnish population. This impact may be even larger in the near future due to the ageing of Finnish population.

Abstract
OBJECTIVE To evaluate the cost-effectiveness of generic atorvastatin 20 mg (A20), branded rosuvastatin 10 mg (R10), generic simvastatin 40 mg (S40) and the combination of generic S40 + branded ezetimibe 10 mg (S40 + EZ10) for the secondary prevention of coronary heart disease (CHD) in Finnish patients not meeting the target goal of low-density lipoprotein cholesterol (LDL-C) with S40. RESEARCH DESIGN AND METHODS A probabilistic Markov model was employed to evaluate the costs and health outcomes of the different therapies based on the cardiovascular events avoided. The model included Framingham risk equations, Finnish population characteristics, event rates, quality of life estimates, resource use and unit costs. The LDL-C lowering efficacies were gathered from a systematic literature review, based on a search of Medline carried out in June 2008 (no time limit). MAIN OUTCOME MEASURES Incremental cost per quality-adjusted life year (QALY) gained and incremental cost per life year gained (LYG). RESULTS The efficacy (LDL-C decrease) gained from switching S40 to S40 + EZ10 was consistent in the literature review, whereas the LDL-C decrease gained from switching S40 to A20/R10 was uncertain. The incremental cost per QALY gained from switching generic S40 was lowest for S40 + EZ10 (22,841 euros [24,017 euros] and 26,595 euros [46,686 euros] for diabetic and non-diabetic men [women], respectively). The respective incremental cost per QALY gained for S40 + EZ10 vs. A20 were 19,738 euros (21,405 euros) and 23,596 euros (40,087 euros). A20 dominated R10. Based on the cost-effectiveness acceptability frontier with a willingness-to-pay value of 30,000 euros per QALY gained, the probability of cost-effectiveness for switching generic S40 to S40 + EZ10 was 100% for men and diabetic women. Sensitivity analyses showed that results were robust. CONCLUSIONS In the Finnish secondary prevention population that is not at goal on S40, switching generic S40 to S40 + EZ10 is more cost-effective than switching S40 to generic A20 or R10.

Due to the limited amount of evidence concerning mortality and morbidity for rosuvastatin, the model was used to transmute the efficiency data of all statins (decrease in total cholesterol) into long-term endpoints (myocardial infarction, death) using risk functions of the FINRISK and 4S studies. The study followed a characterized cohort of 55-year-old Finnish men with an average 3.3-6.6% baseline risk of dying from cardiovascular disease within a 10-year period. MAIN OUTCOME MEASURES Incremental cost-effectiveness ratios (ICERs) for atorvastatin and rosuvastatin, compared with simvastatin, measured as cost of life years gained (euro/LYG) and cost of quality adjusted life years gained (euro/QALY). RESULTS The use of rosuvastatin increased the life expectancy by 0.27 years on average (LYG) compared with simvastatin, producing additional 0.08 quality-adjusted life-years (QALYs). Compared with simvastatin, the cost of one LYG with rosuvastatin was euro10 834 and the cost of one QALY gained was euro36 548 (discount rate 5% per annum). Corresponding figures for atorvastatin were euro31 286/LYG and euro105 599/QALY. CONCLUSIONS If the decision makers' willingness to pay for a QALY gained is around euro40 000 there is a high probability (>50%) that rosuvastatin represents a cost-effective form of therapy in the prevention of CHD in middle-aged men with an average 3.3-6.6% risk of dying within 10 years from cardiovascular disease. However, the true clinical impact of these results needs confirmation from on-going clinical trials, as the role of rosuvastatin in reducing clinical events is pending, but for simvastatin and atorvastatin established.

Dwivedi S. Terminalia arjuna Wight & Arn.--a useful drug for cardiovascular disorders. JOURNAL OF ETHNOPHARMACOLOGY 2007; 114:114-29. [PMID: 17875376 DOI: 10.1016/j.jep.2007.08.003] [Citation(s) in RCA: 70] [Impact Index Per Article: 4.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/03/2006] [Revised: 08/03/2007] [Accepted: 08/07/2007] [Indexed: 05/17/2023]
Abstract
Ancient Indian physicians used the powdered tree bark of Terminalia arjuna Wight & Arn. for alleviating "hritshool" (angina) and other cardiovascular conditions. Its stem bark possesses glycosides, large quantities of flavonoids, tannins and minerals. Flavonoids have been detected to exert antioxidant, anti-inflammatory and lipid lowering effects while glycosides are cardiotonic, thus making Terminalia arjuna unique amongst currently used medicinal plants. In this review an attempt has been made to discuss various aspects of its ethnomedical, pharmacognostical, phytochemical, pharmacological and clinical relevance to cardiovascular conditions. Experimental studies have revealed its bark exerting significant inotropic and hypotensive effect, increasing coronary artery flow and protecting myocardium against ischemic damage. It has also been detected to have mild diuretic, antithrombotic, prostaglandin E(2) enhancing and hypolipidaemic activity. There is ample clinical evidence of its beneficial effect in coronary artery disease alone and along with statin. However, toxicological studies in experimental animals are lacking. Considering its anti-ischemic activity and its potential to correct dyslipidemia, reduce left ventricular mass and increase left ventricular ejection fraction, it is essential to examine the molecular mechanism of its action and its core constituents. Proposition to administer Terminalia arjuna along with statins deserves to be explored in depth for defining its place in the over all management and prevention of coronary artery disease.
