Santos JD, Dawson S, Conefrey C, Isaacs T, Khanum M, Faisal S, Paramasivan S. Most UK cardiovascular disease trial protocols feature criteria that exclude ethnic minority participants: a systematic review. J Clin Epidemiol 2024; 167:111259. [PMID: 38215800 DOI: 10.1016/j.jclinepi.2024.111259] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2023] [Revised: 12/12/2023] [Accepted: 01/08/2024] [Indexed: 01/14/2024]
Abstract
OBJECTIVES We systematically reviewed UK cardiovascular disease (CVD) randomized controlled trial (RCT) protocols to identify the proportion featuring eligibility criteria that may disproportionately exclude ethnic minority (EM) participants. METHODS We searched MEDLINE, Embase, and Cochrane Library databases, January 2014-June 2022, to identify UK CVD RCT protocols. We extracted nonclinical eligibility criteria from trial protocols and inductively categorized the trials by their language, consent, and broad (ambiguous) criteria. Findings are narratively reported. RESULTS Of the seventy included RCT protocols, most (87.1%; 61/70) mentioned consent within the eligibility criteria, with more than two-thirds (68.9%; 42/61) indicating a requirement for 'written' consent. Alternative consent pathways that can aid EM participation were absent. English language requirement was present in 22.9% (16/70) of the studies and 37.1% (26/70) featured broad criteria that are open to interpretation and subject to recruiter bias. Only 4.3% (3/70) protocols mentioned the provision of translation services. CONCLUSION Most UK CVD trial protocols feature eligibility criteria that potentially exclude EM groups. Trial eligibility criteria must be situated within a larger inclusive recruitment framework, where ethnicity is considered alongside other intersecting and disadvantaging identities.

Abstract
BACKGROUND Ethnic minorities make up approximately 14% of the UK workforce. Despite the disproportionate burden of ill-health amongst ethnic minorities, and the increased interest in Diversity, Equity & Inclusion (DE&I) in the workplace, workplace health and wellbeing interventions are still most often designed for the ethnic majority. OBJECTIVE The purpose of this scoping review was to explore the depth and breadth of evidence on the attitudes to and perceptions of health and wellbeing interventions in the workplace within ethnic minority groups in the UK, and to identify gaps in evidence that would provide direction for future research needs. METHODS A scoping review with quality appraisal was undertaken, supplemented by a review of grey literature and a narrative review exploring related evidence from the knowledge bases related to community and cultural adaptation. RESULTS Only three peer-reviewed studies met inclusion criteria, preventing broad conclusions. 14 papers from the community and cultural adaptation literature provided additional information about how health promotion may be approached effectively in the workplace, including the importance of culturally sensitive, people-centred design, and the use of established adaptation frameworks. CONCLUSION The literature suggests a need for improvements in four key areas: (1) reporting of ethnic minorities in data relating to workplace health and wellbeing research, (2) more thorough review of perceptions and attitudes of ethnic minority workers in the UK, (3) design of culturally appropriate interventions that are tested for impact, and (4) testing of the effectiveness of culturally adapted interventions.

Abstract
Background This study aimed to evaluate the severity of alopecia areata (AA) associations with metabolic syndrome, body composition evaluated by bioimpedance techniques, and arterial stiffness based on pulse-wave velocity analysis. Materials and Methods This cross-sectional study was conducted on patients referred to AA Clinic at Razi Hospital in 2021 and 2022. Patients with AA with the Severity of Alopecia Tool (SALT) score above 20% and receiving no systemic therapy were included. Patient demographic and clinical information, symptoms of metabolic syndrome, and bioimpedance factors were collected, and the relationship between disease severity, metabolic syndrome, and bioimpedance indicators was evaluated. Results In this study, 59 patients were examined, with 26 (44.07%) being female and 33 (55.93%) being male. The mean age of the patients was 37.42 years (standard deviation [SD] =11.28). The severity of the disease was assessed using the SALT score, with the mean severity in terms of the percentage being 69.83% (SD = 28.57%). In the regression model, SALT score was independently related to the severity of vascular stiffness after adjusting for the effect of other variables (beta = 0.033, 95% CI = 0.009-0.057, P = 0.046). Moreover, SALT score was significantly related to metabolic syndrome after adjusting for the effect of other variables (OR = 1.035, 95% CI = 1.012-1.059, P = 0.002). Conclusion This study found that AA severity is associated with a higher chance of having metabolic syndrome and arterial stiffness which may lead to cardiovascular diseases in patients with AA, and screening patients regarding cardiometabolic diseases is mandated.

Abstract
There is a long history of BAME under-representation in medical research. Underrepresentation of minority ethnic groups have been assessed by several studies, showing that black and minority ethnic groups were less likely to participate and engage in medical research when compared to white British groups (in relation to education, occupation, health, belief, and attitudes to medical research).There may be several strategies that improve inclusivity, including translation of participant information, culturally specific recruitment, and adaptations to the invitation process. However, with a dearth of literature in the area, there is now a need to contextualise these strategies in relation to renal research.

Abstract
BACKGROUND Ethnicity is not incorporated into standardized pre-operative risk-stratification tools for cardiac surgery. This study compared short-term outcomes following coronary artery bypass graft (CABG) surgery in South Asian and non-Asian patients. METHODS Consecutive patients undergoing isolated CABG surgery via sternotomy between the years 2011 and 2019 were retrospectively analyzed. Initially, 1957 patients were identified (799 South-Asian, 40.8%). The patient groups were then propensity matched according to 10 relevant pre-operative covariates (age, body mass index, pulmonary disease, renal failure, smoking, diabetes, ventricular function, renal failure): 675 non-Asian patients were matched against 675 Asian patients. RESULTS Operative mortality was 1.77% and similar between the two groups (p = 0.447). Multivariate regression analysis found predictors of operative mortality to be pre-operative serum creatinine, age, left ventricular (LV) impairment, and extent of coronary disease. The effect of creatinine on mortality was selective for South-Asian patients (p = 0.015). LV impairment was a predictor of mortality in non-Asian patients, however this effect did not exist in South-Asian patients. Predictors of short-term complications (composite of death, stroke, reoperation, hemofiltration, and pneumonia) were age and creatinine (coefficient 0.002, 95% CI 0.0004-0.004, p = 0.019) in the overall cohort. Subgroup analysis found age to remain a selective negative predictor of complications in South-Asian patients. Cox regression analysis found creatinine, age, and LVEF to influence 10-year survival, whilst ethnicity was not a predictor. CONCLUSION This study highlights the cumulative risk associated with ethnicity and renal disease in predicting short-term outcomes following CABG. This warrants further investigations in larger populations, thus guiding pre-operative risk-stratification.

Boucher BJ. Vitamin D deficiency in British South Asians, a persistent but avoidable problem associated with many health risks (including rickets, T2DM, CVD, COVID-19 and pregnancy complications): the case for correcting this deficiency. Endocr Connect 2022; 11:e220234. [PMID: 36149836 PMCID: PMC9641767 DOI: 10.1530/ec-22-0234] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/27/2022] [Accepted: 09/23/2022] [Indexed: 11/17/2022]
Abstract
High vitamin D deficiency rates, with rickets and osteomalacia, have been common in South Asians (SAs) arriving in Britain since the 1950s with preventable infant deaths from hypocalcaemic status-epilepticus and cardiomyopathy. Vitamin D deficiency increases common SA disorders (type 2 diabetes and cardiovascular disease), recent trials and non-linear Mendelian randomisation studies having shown deficiency to be causal for both disorders. Ethnic minority, obesity, diabetes and social deprivation are recognised COVID-19 risk factors, but vitamin D deficiency is not, despite convincing mechanistic evidence of it. Adjusting analyses for obesity/ethnicity abolishes vitamin D deficiency in COVID-19 risk prediction, but both factors lower serum 25(OH)D specifically. Social deprivation inadequately explains increased ethnic minority COVID-19 risks. SA vitamin D deficiency remains uncorrected after 70 years, official bodies using 'education', 'assimilation' and 'diet' as 'proxies' for ethnic differences and increasing pressures to assimilate. Meanwhile, English rickets was abolished from ~1940 by free 'welfare foods' (meat, milk, eggs, cod liver oil), for all pregnant/nursing mothers and young children (<5 years old). Cod liver oil was withdrawn from antenatal clinics in 1994 (for excessive vitamin A teratogenicity), without alternative provision. The take-up of the 2006 'Healthy-Start' scheme of food-vouchers for low-income families with young children (<3 years old) has been poor, being inaccessible and poorly publicised. COVID-19 pandemic advice for UK adults in 'lockdown' was '400 IU vitamin D/day', inadequate for correcting the deficiency seen winter/summer at 17.5%/5.9% in White, 38.5%/30% in Black and 57.2%/50.8% in SA people in representative UK Biobank subjects when recruited ~14 years ago and remaining similar in 2018. Vitamin D inadequacy worsens many non-skeletal health risks. Not providing vitamin D for preventing SA rickets and osteomalacia continues to be unacceptable, as deficiency-related health risks increase ethnic health disparities, while abolishing vitamin D deficiency would be easier and more cost-effective than correcting any other factor worsening ethnic minority health in Britain.

Abstract
(1) Background: Formula low energy diets (LED) are effective at inducing weight loss and type 2 diabetes (T2DM) remission. However, the effect of LED programmes in ethnic minority groups in the UK is unknown. (2) Methods: A service-evaluation was undertaken of a group-based LED, total diet replacement (TDR) programme in London, UK. The programme included: a 12-week TDR phase, 9-week food reintroduction and a 31-week weight maintenance phase and was delivered by a diabetes multi-disciplinary team. (3) Results: Between November 2018 and March 2020, 216 individuals were referred, 37 commenced the programme, with 29 completing (78%). The majority were of Black British (20%) ethnicity with a mean (SD) age of 50.4 (10.5) years, a body mass index of 34.4 (4.4) kg/m2 and a T2DM duration of 4.2 (3.6) years. At 12 months, 65.7% achieved T2DM remission, with a mean bodyweight loss of 11.6 (8.9) kg. Completers lost 15.8 (5.3) kg, with 31.4% of participants achieving ≥15 kg weight loss. Quality of life measures showed significant improvements. (4) Conclusions: This service evaluation shows for the first time in the UK that a group-based formula LED programme can be effective in achieving T2DM remission and weight loss in an ethnical diverse population.

A Systematic Review of Internet-Based Interventions for the Prevention and Self-Management of Cardiovascular Diseases among People of African Descent.

Abstract
Cardiovascular disease (CVD) risk factors, morbidity, and mortality among people of African descent (PAD) appear to be higher than in the general population. While it has been found that lifestyle changes can prevent around 90% of CVDs, implementing an effective lifestyle programme is expensive and time-consuming. It has been demonstrated that Internet-based interventions (IbIs) can effectively and inexpensively encourage lifestyle modifications to prevent and manage chronic diseases. Although a number of studies have examined the effectiveness of IbIs in the general population, no comprehensive study of the usefulness and acceptability of IbIs among PAD has been conducted. This is the knowledge gap that this study aimed to address. We searched MEDLINE, EMBASE, CINAHL, and Web of Science to identify eligible studies published from inception to February 2022. Thirteen articles met our criteria for inclusion. Our textual narrative synthesis produced inconsistent results; nonetheless, high acceptability of IbIs and a considerable improvement in clinical and behavioural outcomes associated with CVDs were reported in several trials. The findings of this review are constrained by clinical, methodological and statistical variability among the studies. To have a good grasp on the effect of IbIs on behaviour change in PAD at risk of CVDs, large-scale longitudinal studies with long-term follow-up are required.

Abstract
Complex High-risk but indicated Percutaneous coronary interventions (CHiPs) is increasingly common in contemporary practice. However, data on ethnic differences in CHiP types, outcomes, and trends in patients with stable angina are limited; this is pertinent given the population of Black, Asian, and other ethnic minorities (BAME) in Europe is increasing. We conducted a retrospective analysis of CHiP procedures undertaken in patients with stable angina using data obtained from the BCIS (British Cardiovascular Intervention Society) registry (2006 to 2017). CHiP cases were identified and categorized by ethnicity into White and BAME groups. We then performed multivariable regression analysis and propensity score matching to determine adjusted odds ratios (aORs) of in-hospital mortality, major bleeding, and major adverse cardiovascular and cerebral events (MACCEs) in BAME compared with Whites. Of 424,290 procedure records, 105,949 were CHiP (25.0%) (White 89,038 [84%], BAME 16,911 [16%]). BAME patients were younger (median 68.1 vs 70.6 years). Previous coronary artery bypass surgery (33.4% vs 38.3%), followed by chronic total occlusion percutaneous coronary intervention (31.9% vs 32%) were common CHiP variables in both groups. The third common variable was age 80 years and above (23.6%) in White patients and severe vascular calcifications in BAME patients (18.8%). BAME patients had higher rates of diabetes (41.1 vs 23.6%), hypertension (68 vs 66.5%), previous percutaneous coronary intervention (43.7 vs 37.6%), and previous myocardial infarction (44.9 vs 42.5%), (p <0.001 for all). Mortality (aOR 1.1, 95% confidence interval [CI] 0.8 to 1.5) and MACCE (aOR 1.0, 95% CI 0.8 to 1.1) odds were similar among the groups. Bleeding odds (aOR 0.7, 95% CI 0.6 to 0.9) were lower in BAME. In conclusion, CHiP procedures differed among the ethnic groups. BAME patients were younger and had worse cardiometabolic profiles. Similar odds of death and MACCE were seen in BAME compared with their White counterparts. Bleeding odds were 30% lower in the BAME group.

Abstract
Cardiovascular disease remains a major cause of mortality, accounting for a third of all global deaths annually. Although there have been major improvements in our ability to detect and to treat patients with coronary heart disease, most myocardial infarctions occur in previously asymptomatic individuals. Identification of individuals at risk of myocardial infarction remains challenging and primary prevention guidelines rely on the use of cardiovascular risk scores that can be supplemented by coronary artery calcium scores. Coronary artery calcium scores provide a simple surrogate late marker of atherosclerosis but is unable to identify the early high risk non-calcified plaque which can be particularly problematic in younger individuals. Coronary computed tomography angiography is increasingly being used as the imaging strategy of choice in patients with symptoms of coronary heart disease. As an anatomical test, it can non-invasively detect the presence of coronary atherosclerosis, providing clinicians with a strong mandate to commence symptom relieving and preventative therapies. For asymptomatic individuals, it allows precise targeting of therapies to those with coronary heart disease rather than those "at risk" of disease. Moreover, our ability to calculate risk using coronary computed tomography angiography is rapidly improving with the use of techniques, such as plaque quantification and characterisation. These techniques have the potential to provide clinicians with tools to target cardiovascular disease prevention in a precision medicine approach. We here debate the ways in which coronary computed tomography angiography could improve the selection of asymptomatic individuals for preventative therapies over and above risk calculators and calcium scoring.

Abstract
PURPOSE Clozapine is the most effective intervention for treatment-resistant schizophrenia (TRS). Several studies report ethnic disparities in clozapine treatment. However, few studies restrict analyses to TRS cohorts alone or address confounding by benign ethnic neutropenia. This study investigates ethnic equity in access to clozapine treatment for people with treatment-resistant schizophrenia spectrum disorder. METHODS A retrospective cohort study, using information from 11 years of clinical records (2007-2017) from the South London and Maudsley NHS Trust. We identified a cohort of service-users with TRS using a validated algorithm. We investigated associations between ethnicity and clozapine treatment, adjusting for sociodemographic factors, psychiatric multi-morbidity, substance misuse, neutropenia, and service-use. RESULTS Among 2239 cases of TRS, Black service-users were less likely to be receive clozapine compared with White British service-users after adjusting for confounders (Black African aOR = 0.49, 95% CI [0.33, 0.74], p = 0.001; Black Caribbean aOR = 0.64, 95% CI [0.43, 0.93], p = 0.019; Black British aOR = 0.61, 95% CI [0.41, 0.91], p = 0.016). It was additionally observed that neutropenia was not related to treatment with clozapine. Also, a detention under the Mental Health Act was negatively associated clozapine receipt, suggesting people with TRS who were detained are less likely to be treated with clozapine. CONCLUSION Black service-users with TRS were less likely to receive clozapine than White British service-users. Considering the protective effect of treatment with clozapine, these inequities may place Black service-users at higher risk for hospital admissions and mortality.

Ethnic differences in cardiovascular risk: examining differential exposure and susceptibility to risk factors. BMC Med 2022; 20:149. [PMID: 35473626 PMCID: PMC9042646 DOI: 10.1186/s12916-022-02337-w] [Citation(s) in RCA: 22] [Impact Index Per Article: 11.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/03/2021] [Accepted: 03/14/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Ethnic differences in cardiovascular disease (CVD) risk have been known for decades, but a systematic exploration of how exposure and susceptibility to risk factors may contribute is lacking. This study aimed to investigate the potential impact of differential exposure and susceptibility between South Asian, Black, and White individuals. METHODS This is a population-based prospective cohort study of UK Biobank participants with a median follow-up of 11.3 years. The association between ethnic group and CVD risk was studied. Additional risk factors were then adjusted to examine mediations. Moderation analysis was conducted to identify whether risk factors had a stronger association in the ethnic minority groups. Population attributable fractions were also calculated to quantify the relative contributions of risk factors for each ethnic group. RESULTS When adjusted for only age and sex, there was a higher risk of CVD among South Asian (n=8815; HR [95% CI] 1.69 [1.59-1.79]) and Black (n=7526; HR [95% CI] 1.12 [1.03-1.22]) compared with White participants (n=434,809). The excess risk of Black participants was completely attenuated following adjustment for deprivation. Compared with White participants, the associations of BMI, triglycerides, and HbA1c with CVD were stronger in South Asians. Adiposity was attributable to the highest proportion of CVD regardless of ethnicity. Smoking had the second largest contribution to CVD among White and Black participants, and HbA1c among South Asian participants. CONCLUSIONS Adiposity is an important risk factor for CVD regardless of ethnicity. Ethnic inequalities in CVD incidence may be best tackled by targeting interventions according to ethnic differences in risk profiles.

Abstract
BACKGROUND Hypertension is common in individuals with chronic kidney disease and both conditions are associated with adverse outcomes including cardiovascular morbidity. Therefore, it is clinically important to identify methods of risk prediction in individuals with chronic kidney disease. Blood pressure variability has recently emerged as a predictor of cardiovascular events and mortality in the general population, with growing evidence indicating that it may play a similar role in individuals with chronic kidney disease. However, there have been no large studies assessing blood pressure variability in individuals with chronic kidney disease in primary care, where the majority of these patients are managed. METHOD Using a retrospective observational study design, we analyzed routinely collected blood pressure readings from 16 999 individuals in The Leicester and County Chronic Kidney Disease cohort. Standard deviation, coefficient of variation and average real variability of SBP were used to calculate blood pressure variability. RESULTS During a median follow-up of 5.0 (IQR 3.3--5.0) years, 2053 (12.1%) patients had cardiovascular events, death occurred in 5021 (29.6%) individuals and 156 (0.9%) individuals had endstage kidney disease events. In adjusted models, standard deviation and coefficient of variation were associated with cardiovascular events, all-cause mortality and endstage kidney disease. Average real variability was associated with all-cause mortality and cardiovascular events, but not endstage kidney disease. CONCLUSION Blood pressure variability may be an accessible, routinely collected, noninvasive measure for stratifying the risk of adverse events in individuals with chronic kidney disease in a primary care setting.

Abstract
BACKGROUND AND AIMS Palpitations are a common presentation in primary care. Guidelines have been developed to identify patients with palpitations who require further assessment by a cardiologist in secondary care. However, patients that do not meet guideline thresholds for referrals are still referred to secondary care services. This audit evaluated the adherence to referral guidelines at our trust and assessed the characteristics of patients who were referred appropriately versus those referred without meeting guideline referral thresholds (inappropriate referral). RESULTS Palpitation referrals to a single cardiology outpatient clinic were assessed (n = 66). Half the patients referred for palpitations were referred inappropriately (n = 34, 51.5%). Patients referred inappropriately were more likely to have a benign diagnosis after assessment (91.2%). These patients also had significantly fewer investigations [mean difference of 1.1 (confidence interval: 0.6-1.6)]. Specialist investigations, such as cardiac event recorders (P < 0.05) and cardiac magnetic resonance imaging (P < 0.05) were less likely to be used in inappropriately referred patients. CONCLUSIONS The results from this audit provide early evidence that there are a significant number of patients who are being referred that could be managed in primary care. Further studies are needed to confirm our findings in larger cohorts and to establish the underlying reasons for inappropriate referrals.

Abstract
BACKGROUND The NHS Health Check programme aims to reduce the risk of common preventable diseases by providing risk information and behaviour change advice. Failure to deliver the consultation appropriately could undermine its efficacy. To date, to the authors' knowledge, there are no published data on the fidelity of delivery of NHS Health Checks. AIM To assess the fidelity of delivery of NHS Health Checks in general practice. DESIGN & SETTING Fidelity assessment of video and audio recordings of NHS Health Check consultations conducted in four GP practices across the East of England. METHOD A secondary analysis of 38 NHS Health Check consultations, which were video or audio recorded as part of a pilot study of introducing discussions of cancer risk into NHS Health Checks. Using a checklist based on the NHS Health Check Best Practice Guidance, fidelity of delivery was assessed as the proportion of key elements completed during the consultations. RESULTS The mean number of elements of the NHS Health Check completed across all consultations was 14.5/18 (80.6%), with a range of 10 to 17 (55.6% to 94.4%). The mean fidelity for risk assessment, risk communication, and risk management sections was 8.7/10 (87.0%), 4.1/5 (82.0%), and 1.7/3 (56.7%), respectively. Clinically appropriate lifestyle advice was given in 34/38 consultations. Elements with the lowest fidelity were ethnicity assessment (n = 12/38; 31.6%), family history of cardiovascular disease (CVD) assessment (n = 25/38; 65.8%), AUDIT-C communication (n = 13/38; 34.2%), and dementia risk management (n = 6/38; 15.8%). CONCLUSION Although fidelity of delivery was high overall, important elements of the NHS Health Check were being regularly omitted. Opportunities for behaviour change, particularly relating to alcohol consumption and dementia risk management, may be being missed.

Abstract
INTRODUCTION There have been recent mounting concerns regarding multiple reports stating a significantly elevated relative-risk of COVID-19 mortality amongst the Black and Minority Ethnic (BAME) population. An urgent national enquiry investigating the possible reasons for this phenomenon has been issued in the UK. Inflammation is at the forefront of COVID-19 research as disease severity appears to correlate with pro-inflammatory cytokine dysregulation. This narrative review aims to shed light on the novel, pathophysiological role of inflammation in contributing towards the increased COVID-19 mortality risk amongst the BAME population. METHODS Searches in PubMed, Medline, Scopus, medRxiv and Google Scholar were performed to identify articles published in English from inception to 18th June 2020. These databases were searched using keywords including: 'COVID-19' or 'Black and Minority Ethnic' or 'Inflammation'. A narrative review was synthesized using these included articles. RESULTS We suggest a novel pathophysiological mechanism by which acute inflammation from COVID-19 may augment existing chronic inflammation, in order to potentiate a 'cytokine storm' and thus the more severe disease phenotype observed in the BAME population. Obesity, insulin resistance, cardiovascular disease, psychological stress, chronic infections and genetic predispositions are all relevant factors which may be contributing to elevated chronic systemic inflammation amongst the BAME population. CONCLUSION Overall, this review provides early insights and directions for ongoing research regarding the pathophysiological mechanisms that may explain the severe COVID-19 disease phenotype observed amongst the BAME population. We suggest 'personalization' of chronic disease management, which can be used with other interventions, in order to tackle this.

Abstract
AIMS/HYPOTHESIS The aim of this work was to determine how weight patterns together with blood glucose, BP and lipids vary at diagnosis of diabetes by age, sex and ethnicity. METHODS Using the UK Clinical Practice Research Datalink, we identified people with type 2 diabetes (n = 187,601) diagnosed in 1998-2015 and compared their weights, HbA1c, BP and lipid levels at diagnosis with age-matched people without diabetes (n = 906,182), by sex and ethnic group. RESULTS Younger age at diagnosis was associated with greater adjusted mean difference (95% CI) in weight between those with vs without type 2 diabetes: 18.7 (18.3, 19.1) kg at age 20-39 years and 5.3 (5.0, 5.5) kg at age ≥ 80 years. Weight differentials were maximal in white women, and were around double in white people compared with South Asian and black people. Despite lower absolute values, BP differences were also greater at younger age of diabetes onset: 7 (6, 7) mmHg at age 20-39 years vs -0.5 (-0.9, -0.2) at age ≥ 80 years. BP differences were greatest in white people, and especially in women. Triacylglycerol level differences were greatest in younger men. Finally, HbA1c levels were also higher with younger onset diabetes, particularly in black people. CONCLUSIONS/INTERPRETATION At diagnosis of type 2 diabetes, when compared with people without diabetes, weight and BP differentials were greater in younger vs older people, in women vs men and in white vs South Asian and black people. These differences were observed even though South Asian and black people tend to develop diabetes a decade earlier with either similar or greater dysglycaemia. These striking patterns may have implications for management and prevention. Graphical abstract.

Abstract
BACKGROUND Metabolic syndrome is a constellation of various cardiovascular and type 2 diabetes risk factors, such as abdominal obesity, atherogenic dyslipidemia, high blood pressure, and high blood glucose, but its prevalence varies widely by geographical region, sex, and race/ethnicity. The objective of this study is to examine the prevalence and incidence of metabolic syndrome among adults of different racial/ethnic origins in high-income countries. METHODS We designed and registered a study protocol for a systematic review of descriptive epidemiological data. Observational studies (e.g., cross sectional and cohort studies) reporting morbidity data of metabolic syndrome and conducted in a wide range of adult people (e.g., different racial/ethnic origins, including migrants) will be included. The primary outcome will be the prevalence and incidence of metabolic syndrome. Secondary outcomes will be the prevalence and incidence of individual components of metabolic syndrome (e.g., abdominal obesity, dyslipidemia, high blood pressure, and high blood glucose). Literature searches will be conducted in several electronic databases (from inception onwards), including MEDLINE, Web of Science Core Collection (Science Citation Index and Social Science Citation Index), CINAHL, and Cochrane Library. Two investigators will independently screen all reference titles, abstracts, and full-text articles. The methodological quality (or potential bias) of selected studies will be appraised using an appropriate tool. Our results will be described narratively. Random-effects meta-analysis will be conducted, if feasible and appropriate. Additional analyses will be conducted to explore the potential sources of heterogeneity. CONCLUSION This systematic review will identify, evaluate, and integrate prevalence and incidence data of metabolic syndrome, with focus on racial/ethnic differences in high-income countries. We anticipate our findings may guide policy formulation and identify knowledge gaps in the literature that future research should address. SYSTEMATIC REVIEW REGISTRATION PROSPERO, CRD42020157189.

Abstract
Europe's population is becoming increasingly ethnically diverse, and epidemiological studies indicate that there are remarkable differences in cardio-metabolic risk factors between ethnic groups living in the same area. Variations observed in the distribution of cardiovascular risk factors in these communities may therefore help explain-at least in part-the different burdens on cardiovascular diseases. So far, the underlying pathophysiology leading to ethnic variations in the prevalence of cardio-metabolic risk factors is still poorly understood but it is likely to represent the complex interactions from several innate and environmental factors. Tailored prevention and treatment strategies should therefore be implemented in those "high-risk populations," but data derived from randomized clinical trials are still limited. This article will provide an overview on the role of ethnicity on cardio-metabolic risk factors and cardiovascular diseases, focusing on type 2 diabetes and dyslipidemia based mainly on Dutch and British data.

Abstract
OBJECTIVES Cardiovascular mortality in Western Asia is high and still rising. However, most data documented on risk prediction has been derived from Western countries and few population-based cohort studies have been conducted in this region. The current study aimed to present the process of pooling data and cardiovascular disease (CVD) mortality incidences for four Iranian cohorts. METHODS From the Iran Cohort Consortium, the Golestan Cohort Study (GCS), Tehran Lipid and Glucose Study, Isfahan Cohort Study (ICS) and the Shahroud Eye Cohort Study (ShECS) were eligible for the current study since they had appropriate data and follow-up visits. Age-standardised CVD mortality rates were estimated for ages 40-80 and 40-65 years. Cox regression was used to compare mortalities among cohorts. Adjusted marginal rates were calculated using Poisson regression. RESULTS Overall, 61 291 participants (34 880 women) aged 40-80 years, free of CVD at baseline, were included. During 504 606 person-years of follow-up, 1981 CVD deaths (885 women) occurred. Age-standardised/sex-standardised premature CVD mortality rates were estimated from 133 per 100 000 person-years (95% CI 81 to 184) in ShECS to 366 (95% CI 342 to 389) in the GCS. Compared with urban women, rural women had higher CVD mortality in the GCS but not in the ICS. The GCS population had a higher risk of CVD mortality, compared with the others, adjusted for conventional CVD risk factors. CONCLUSIONS The incidence of CVD mortality is high with some differences between urban and rural cohorts in Iran as a Western Asian country. Pooling data facilitates the opportunity to globally evaluate risk prediction models.

Abstract
ObjectivesTo investigate ethnic differences in susceptibility to bradycardias in South Asian and white European patients in the UK by determining rates of permanent pacemaker (PPM) implantation for sinus node dysfunction (SND) and atrioventricular block (AVB) in each ethnic group.MethodsWe carried out a retrospective cohort study into new PPM implantation during the period from 1 May 2006 to 31 March 2014, in patients of South Asian and Caucasian ethnicity resident in Leicestershire, UK. Numbers of individuals at risk in each ethnic group were derived from UK National Census data of 2011. Crude, and age-standardised incidence rates and risk ratios per 1000 population of PPM implantation were calculated for Caucasians and South Asians.ResultsDuring the study period, 4883 individuals from the Leicestershire population of 980 328 underwent PPM implantation, a cumulative implantation rate of 4.98/1000 population. The population cumulative PPM implantation rate for SND was 1.74/1000, AVB 2.83/1000 and other indications 0.38/1000 population. The crude incidence in Caucasians (6.15/1000 population) was higher than in South Asians (1.07/1000 population) and remained higher after age standardisation (5.60/1000 vs 2.03/1000, P<0.001). The age-standardised cumulative PPM implantation rates were lower in South Asians for both SND (0.53/1000 in South Asians; 1.97/1000 in Caucasians, P<0.001) and AVB (1.30/1000 in South Asians; 3.17/1000 in Caucasians, P<0.001). Standardised risk ratios (95% CI) for PPM implantation in South Asians compared with Caucasians for all pacing indications, SND and AVB were 0.36 (95% CI 0.36 to 0.37), 0.27 (95% CI 0.27 to 0.28) and 0.41 (95% CI 0.41 to 0.42), respectively.ConclusionsRates of PPM implantation are lower in South Asians residing in the UK, compared with Caucasians. This observation raises the possibility of lower inherent susceptibility to bradycardias in South Asians compared with Caucasians. Studies aimed at identifying underlying mechanisms, including possible genetic differences, are warranted.

Interarm Difference in Systolic Blood Pressure in Different Ethnic Groups and Relationship to the "White Coat Effect": A Cross-Sectional Study. Am J Hypertens 2017; 30:884-891. [PMID: 28475667 PMCID: PMC5861584 DOI: 10.1093/ajh/hpx073] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2016] [Accepted: 04/05/2017] [Indexed: 12/17/2022] Open
Abstract
BACKGROUND Interarm differences (IADs) ≥10 mm Hg in systolic blood pressure (BP) are associated with greater incidence of cardiovascular disease. The effect of ethnicity and the white coat effect (WCE) on significant systolic IADs (ssIADs) are not well understood. METHODS Differences in BP by ethnicity for different methods of BP measurement were examined in 770 people (300 White British, 241 South Asian, 229 African-Caribbean). Repeated clinic measurements were obtained simultaneously in the right and left arm using 2 BPTru monitors and comparisons made between the first reading, mean of second and third and mean of second to sixth readings for patients with, and without known hypertension. All patients had ambulatory BP monitoring (ABPM). WCE was defined as systolic clinic BP ≥10 mm Hg higher than daytime ABPM. RESULTS No significant differences were seen in the prevalence of ssIAD between ethnicities whichever combinations of BP measurement were used and regardless of hypertensive status. ssIADs fell between the 1st measurement (161, 22%), 2nd/3rd (113, 16%), and 2nd–6th (78, 11%) (1st vs. 2nd/3rd and 2nd–6th, P < 0.001). Hypertensives with a WCE were more likely to have ssIADs on 1st, (odds ratio [OR] 1.73 (95% confidence interval 1.04–2.86); 2nd/3rd, (OR 3.05 (1.68–5.53); and 2nd–6th measurements, (OR 2.58 (1.22–5.44). Nonhypertensive participants with a WCE were more likely to have a ssIAD on their first measurement (OR 3.82 (1.77 to −8.25) only. CONCLUSIONS ssIAD prevalence does not vary with ethnicity regardless of hypertensive status but is affected by the number of readings, suggesting the influence of WCE. Multiple readings should be used to confirm ssIADs.

Abstract
BACKGROUND The Hospital Admission Risk Program (HARP) Cardiac Coach Program at Royal Melbourne Hospital has evolved to include a Greek and Italian service, developed in response to the diverse local community and supported by evidence that Culturally and Linguistically Diverse (CALD) groups both perceive health and respond to health care services and information, differently. This paper aims to evaluate if a phone-based cardiac coaching program can be adapted to the Greek and Italian populations using the English cohort as a comparator. METHODS We retrospectively analysed cardiovascular risk profiles at recruitment into and at discharge from the program. Patients (n=383) were recruited after an acute coronary event or intervention between June 2011 and June 2013. Recruitment was into the English (n=301 patients (79%)) Greek (40 (10%)) or Italian (42 (11%)) model. Data was collected on demographic information and risk factor status at entry and discharge from the program: waist circumference, weight, height, lipid profile, HbA1c, smoking status and physical activity. A comparison of the proportion of patients meeting the defined targets across the English, Italian and Greek cohorts was performed, with multivariate logistic regression analysis applied to adjust for differences in baseline variables. RESULTS There were baseline differences in age, smoking history, total cholesterol and cholesterol fractions, diastolic blood pressure, weight and physical activity between the cohorts. At discharge, the proportion of patients meeting targets within each cohort were similar. CONCLUSION A phone-based integrated disease management program can be adapted to CALD patients, achieving comparable outcomes as compared with an English-speaking cohort. Health services need to respond to their local needs and be flexible in program delivery in order to benefit as many patients as possible.

The comparative efficacy of angiosome-directed and indirect revascularisation strategies to aid healing of chronic foot wounds in patients with co-morbid diabetes mellitus and critical limb ischaemia: a literature review. J Foot Ankle Res 2017; 10:26. [PMID: 28670345 PMCID: PMC5490238 DOI: 10.1186/s13047-017-0206-5] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/28/2017] [Accepted: 06/06/2017] [Indexed: 12/18/2022] Open
Abstract
BACKGROUND Ischaemic ulcerations have been reported to persist and/or deteriorate despite technically successful revascularisations; a higher incidence of which affects patients with diabetes and critical limb ischaemia. In the context of wound healing, it is unclear if applications of the angiosome concept in 'direct revascularisation' (DR) would be able to aid the healing of chronic foot ulcerations better than the current 'best vessel' or 'indirect revascularisation' (IR) strategy in patients with co-morbid diabetes and critical limb ischaemia. METHODS A literature search was conducted in eight electronic databases, namely AMED, CINAHL, The Cochrane Library, ProQuest Health & Medicine Complete, ProQuest Nursing & Allied Health Source, PubMed, ScienceDirect and TRIP database. Articles were initially screened against a pre-established inclusion and exclusion criteria to determine eligibility and subsequently appraised using the Newcastle-Ottawa Scale. RESULTS Five retrospective studies of varying methodological quality were eligible for inclusion in this review. Critical analysis of an aggregated population (n = 280) from methodologically stronger studies indicates better wound healing outcomes in subjects who had undergone DR as compared to IR (p < 0.001; p = 0.04). DR also appears to result in a nearly twofold increase in probability of wound healing within 12 months (hazard ratio, 1.97; 95% CI, 1.34-2.90). This suggests that achieving direct arterial perfusion to the site of ulceration may be important for the healing of chronic diabetic foot ulcerations. CONCLUSION Incorporating an angiosome-directed approach in the lower limb revascularisation strategy could be a very useful adjunct to a solely indirect approach, which could increase the likelihood of wound healing. With the limited data currently available, findings appear promising and merit from further investigation. Additional research to form a solid evidence base for this revised strategy in patients with co-morbid diabetes and critical limb ischaemia is warranted.

Abstract
INTRODUCTION Coronary artery disease (CAD) is a leading cause of death worldwide. The association of socioeconomic status with CAD is supported by numerous epidemiological studies. Whether such factors also impact the number of diseased coronary vessels and its severity is not well established. MATERIALS AND METHODS We conducted a prospective multicentre, multi-ethnic, cross sectional observational study of consecutive patients undergoing coronary angiography (CAG) at 5 hospitals in the Kingdom of Saudi Arabia and the United Arab Emirates. Baseline demographics, socioeconomic, and clinical variables were collected for all patients. Significant CAD was defined as ≥70% luminal stenosis in a major epicardial vessel. Left main disease (LMD) was defined as ≥50% stenosis in the left main coronary artery. Multi-vessel disease (MVD) was defined as having >1 significant CAD. RESULTS Of 1,068 patients (age 59 ± 13, female 28%, diabetes 56%, hypertension 60%, history of CAD 43%), 792 (74%) were from urban and remainder (26%) from rural communities. Patients from rural centres were older (61 ± 12 vs 58 ± 13), and more likely to have a history of diabetes (63 vs 54%), hypertension (74 vs 55%), dyslipidaemia (78 vs 59%), CAD (50 vs 41%) and percutaneous coronary intervention (PCI) (27 vs 21%). The two groups differed significantly in terms of income level, employment status and indication for angiography. After adjusting for baseline differences, patients living in a rural area were more likely to have significant CAD (adjusted OR 2.40 [1.47, 3.97]), MVD (adjusted OR 1.76 [1.18, 2.63]) and LMD (adjusted OR 1.71 [1.04, 2.82]). Higher income was also associated with a higher risk for significant CAD (adjusted OR 6.97 [2.30, 21.09]) and MVD (adjusted OR 2.49 [1.11, 5.56]), while unemployment was associated with a higher risk of significant CAD (adjusted OR 2.21, [1.27, 3.85]). CONCLUSION Communal and socioeconomic factors are associated with higher odds of significant CAD and MVD in the group of patients referred for CAG. The underpinnings of these associations (e.g. pathophysiologic factors, access to care, and system-wide determinants of quality) require further study.

Abstract
Cardiovascular disease (CVD) is increasing in Middle Eastern countries. Depression is associated with increased morbidity and mortality rates among cardiovascular (CV) patients. Early detection of and intervention for depression among CV patients can reduce morbidity and mortality and save health care costs. Public information on mental health care needs of Arab CV patients living in Middle East regions is scattered and limited. This literature review surveyed and summarized research studies to learn what is known about the relationship between depression and CVD in Middle Eastern populations. The information will raise awareness among health care professionals and policy makers regarding the clinical significance of depression in Arab CV patients. It might contribute to development of culturally appropriate and effective mental health care services. Multiple databases were searched and 60 articles were assessed, including studies that investigated depression in Arab CV patient populations, physiological mechanisms of depression-CVD comorbidity, and intervention strategies that affect CV risk in depressed Arab patients. We discuss the extent to which this issue has been explored in Arab populations living in Middle East regions and Arab populations living abroad. We recommend that more comprehensive and in-depth research studies be conducted with Arab cardiac patients to enable implementation of culturally appropriate and effective mental health care interventions.

Abstract
BACKGROUND There are various reports of higher mortality rates occurring after admissions over the weekend and during after-hours. This study aimed to determine if there was a difference in mortality rates occurring during the weekend and after-hours among cardiovascular admissions in a tertiary hospital in Nigeria. METHODS A review of cardiovascular admissions (including stroke) was carried out at the University of Calabar Teaching Hospital in Nigeria from January 2010 to December 2013. All admissions to the medical wards from the emergency department and medical out-patient department clinics during the study period were included. RESULTS A total of 339 patients were studied and stroke was the commonest type of cardiovascular disease (CVD) admitted (187; 55.2%). Hypertension was the commonest cause of heart failure (70; 48.6%). Presentation to hospital during after-hours and length of stay of more than 14 days were significant predictors of death (OR: 3.37; 0.22). CONCLUSION An increase in CVD mortality rates occurred during after-hours, most likely a consequence of uneven staffing patterns and poor access to equipment. Healthcare providers in Nigeria need to consider remedies to this with a view to reducing excess mortality rates.

Abstract
The 20th century saw cardiovascular disease ascend as the leading cause of death in the world. In response to the new challenge that heart disease imposed, the cardiovascular community responded with ground breaking innovations in the form of evidence based medications that have improved survival, imaging modalities that allow for precise diagnosis and guide treatment; revascularization strategies that have not only reduced morbidity, but also improved survival following an acute myocardial infarction. However the benefits have not been distributed equitably and as a result disparities have arisen in cardiovascular care. There is tremendous data from the United States demonstrating the many phenotypical forms of disparities. This paper takes a global view of disparities and highlights that disparate care is not limited to the United States and it is another challenge that the medical community should rise and face head on.

Abstract
OBJECTIVE Hypertension is a major problem among European ethnic minority groups. We assessed the current situation of hypertension prevalence and its management among a multi-ethnic population in Amsterdam, The Netherlands. METHODS Data from the HELIUS study were used including 12,974 participants (1871 Ghanaian, 2184 African Surinamese, 2278 South-Asian Surinamese, 2277 Turkish, 2222 Moroccan and 2142 Dutch origin people), aged 18-70 years. Comparisons among groups were made using proportions and age-adjusted prevalence ratios (PRs). RESULTS Hypertension prevalence ranged from 24% and 16% in Moroccan men and women to 52% and 62% in Ghanaian men and women. Except for Moroccan women, age-adjusted PR of hypertension was higher in all the ethnic minority groups than in Dutch. Among hypertensives, ethnic minority groups generally had higher levels of hypertension awareness and BP lowering treatment than Dutch. Moreover, prevalence rates for the prescription of more than one BP lowering drug were generally higher in African and South-Asian origin groups compared with Dutch origin people. By contrast, BP control levels were lower in all the ethnic groups than in Dutch, with control rates being significantly lower in Ghanaian men (26%, PR=0.49; 95% CI, 0.37-0.66) and women (45%, PR=0.64; 0.52-0.77), African-Surinamese men (30%, PR=0.61; 0.46-0.81) and women (45%, PR=0.72; 0.51-0.77), and South-Asian Surinamese men (43%, PR=0.77; 0.61-0.97) and women (47%, PR=0.76; 0.63-0.92) compared with Dutch men (53%) and women (61%). CONCLUSION Our findings indicate poor BP control in ethnic minority groups despite the high treatment levels. More work is needed to unravel the potential factors contributing to the poor control in order to improve BP control in ethnic minority groups, particularly among African and South-Asian origin groups.

Abstract
OBJECTIVE Although few studies have examined cardiovascular disease in Asian-American subgroups separately, limited data in Asian Americans strongly suggest that some subgroups are at increased risk. The present study examined modifiable cardiovascular risk factor profiles as a function of Asian ethnicity. METHODS This descriptive cross-sectional pilot study recruited Asian-American women (N=147) in northeast Florida including Cambodians (n=39), Chinese (n=36), Filipinos (n=49), and Vietnamese (n=23). Risk factors included blood pressure, body mass index, waist circumference and blood lipids. RESULTS Filipino participants (41%) had ≥4 risk factors compared to 21% Cambodian, 13% Vietnamese and 0% Chinese. The Chinese had significantly more participants (44%) with the absence of CVD risk factors compared to all other subgroups. Obesity rate (18%), mean BMI: 26 ± 5 kg/m(2) and mean triglycerides (173 ± 103 mg/dL) were highest in Filipinas (n=49). The Chinese (n=36) had a low rate (4%) of obesity with a mean BMI of 23 ± 3 kg/m(2) and the least risk factors along with the lowest triglycerides (88 ± 44 mg/dL). Cambodians (n=39; BMI of 24 ± 3 kg/m(2)) and Vietnamese (n=23; BMI: 22 ± 3 kg/m(2)) had low rates of obesity with comparable rates of unhealthy lipids and hypertension as the Filipinas. CONCLUSIONS Modifiable CVD risk factor profiles significantly differed as a function of ethnicity supporting the premise that Asian-American women cannot be categorized as one group and the traditional "one size fits all" prevention or treatment of CVD risk factors should be re-considered.

METHODS Ninety-one interviews were undertaken with people who either had (n = 48) or had not (n = 43) responded to the invitation to take part in a community heart failure screening study. These were split across four ethnic groups (African Caribbean, Bangladeshi, Indian and Pakistani) and between men and women. Participants were interviewed once, face-to-face, either in English or with an interpreter if they wished. Interview transcripts were analysed thematically. RESULTS The main reason for participating in the screening study was for a health/heart check. Many participants either had not understood that it was research or had not known what this meant. Most people who did not participate had not remembered receiving the invitation or had been unavailable at the time. Few participants, including those who had and those who had not participated in the screening study, had any understanding of the objectives and nature of research. Once this had been briefly explained to them, many described altruistic reasons for why they would participate in research in the future. CONCLUSIONS We have shown that South Asians and Black African-Caribbean communities are willing to take part in research as long as they are approached directly and the reasons for the research and potential benefits are explained clearly to them.

Abstract
BACKGROUND Cardiovascular disease (CVD) is the leading cause of death globally. Vascular risk assessment is recognized as playing a key role in reducing premature CVD-related morbidity and mortality. The current study evaluated the effectiveness of a pharmacy-led risk assessment service in Leicester City, UK. METHODS The vascular risk assessment was offered opportunistically to individuals between 40 and 70 years without any prior diagnosis of CVD on attending their community pharmacist. Individuals were risk stratified using the Framingham score and those classified as high risk were referred to their general practitioner (GP). RESULTS Overall, 2521 individuals were recruited from 39 pharmacies consisting of 1059 (42%) males, 1696 (67%) South Asians and 199 (7.9%) individuals not registered with a GP. A total of 462 (18%) individuals were referred to primary care and 52.6% of a representative subset were subsequently recorded as having attended an appointment with their GP; diagnoses and treatments commenced were recorded. CONCLUSIONS Cardiovascular risk assessment led by community pharmacies can successfully assess people from large, multi-ethnic UK populations and identify those at high cardiovascular risk or with undiagnosed cardiovascular disease. The service may improve rates of assessments undertaken by individuals who do not access health care through traditional routes.

Abstract
BACKGROUND Migration from sub-Saharan Africa to industrialized countries has increased tremendously over the last few decades, yet very little is known about the health status of sub-Saharan African populations living in industrialized communities. The aim of this study was to assess prevalence, levels of awareness, treatment, and control of hypertension among the largest sub-Saharan African group (Ghanaians) living in the Netherlands. METHODS Cross-sectional study of Ghanaian adults aged 18-60 years in Amsterdam, the Netherlands. RESULTS The overall prevalence of hypertension was 55%. Of these, about half were aware of their condition, 45% were receiving antihypertensive medication, and 15% were controlled (blood pressure <140/90 mmHg). The prevalence rates of hypertension, awareness, and treatment were similar among males and females. However, males had a lower blood pressure control rate than females. Among all hypertensives, 22% of females had their blood pressure controlled compared with 5.8% in males: adjusted prevalence ratio (APR) 3.94 (95% CI 1.05-14.79). Among those receiving treatment for their hypertension, 48% of females were controlled compared with only 13% of males: APR 4.08 (95% CI 1.20-13.87). CONCLUSION Hypertension is a major problem among this recently migrated sub-Saharan African population. Furthermore, hypertension control rate is very low particularly in males. Urgent measures are needed to halt the increasing prevalence of hypertension and to improve hypertension control among these populations.

Abstract
Individuals of South Asian descent have a high prevalence of comorbidities that are risk factors for the development of heart failure (HF), including diabetes mellitus and metabolic syndrome. However, little is known about the prevalence of HF, its management and prognosis for this population compared to Caucasians. Therefore, a literature review relating to the nature, outcome and treatment of HF in South Asian patients compared to Caucasians was conducted. It was anticipated that collating existing studies in this manner would be useful for guiding professionals in managing HF within this ethnic group, given that to achieve optimal care, regimens need to take into account cultural differences that may impact on adherence. Reviewed literature showed that South Asians with HF were more likely to be younger and have diabetes and hypertension. These papers also implied that outcomes for South Asians with HF were similar or even better than for Caucasians. The review highlighted the under-representation of South Asians in HF trials, meaning that evidence-based recommendations tailored to this specific population are limited. This is an important consideration because ethnic differences in response to medication have been reported; it cannot be assumed that treatments shown to work for Caucasians will be efficacious for those from minority ethnic groups.

Abstract
BACKGROUND AND OBJECTIVE Hypertension and obesity are major contributors to cardiovascular disease, and the relationship between these conditions is known to vary among ethnicities. However, this relationship has not previously been examined in aboriginal populations. The present investigation aimed to identify and compare this relationship among white (n = 3566), aboriginal (n = 850), East Asian (n = 446), and South Asian (n = 222) individuals from the province of British Columbia, Canada. METHODS Blood pressure, BMI, and waist circumference were directly measured along with self-reported antihypertensive medication usage. Relative risk ratios were calculated to evaluate the risk of hypertension among individuals of varying BMI and waist circumference measurements. The relative risks of hypertension were compared both within and between four ethnic groups. RESULTS Greater relative risks for hypertension were observed among individuals with increased BMI or increased waist circumference among all four ethnic groups. Aboriginal individuals appear to experience the greatest increases in relative risk for hypertension with increased BMI or waist circumference compared to other ethnic groups. The differences in the risk of developing hypertension between aboriginal and white populations appear to be largely associated with differences in body composition (i.e., BMI or waist circumference). East Asian and South Asian populations experience greater relative risk for hypertension than white populations at the same level of BMI or waist circumference. CONCLUSION Hypertension prevention and treatment strategies among aboriginal, East Asian, and South Asian populations should target reducing fat mass and abdominal fat.

Abstract
BACKGROUND Evidence suggests a higher prevalence of type 2 diabetes (T2D) in The Netherlands than in England, although generalized obesity prevalence is substantially lower in The Netherlands. Metabolic syndrome (MS) is more strongly associated with the risk of progression to T2D than generalized obesity. Therefore examining MS may help to better understand the differences in T2D between the two countries. We assessed whether the Dutch and English differences in T2D prevalence reflect similar differences in MS in Whites, South-Asian Indians and African-Caribbeans living in these two countries. METHODS Secondary analyses of population-based studies of 3010 participants aged 35-60 years. Metabolic syndrome was defined according to the International Diabetes Federation criteria. Prevalence ratios (PRs) were estimated using regression models. RESULTS In general, the Dutch ethnic groups had a higher prevalence of MS than their English counterparts. Adjusted PRs were 1.37[95% confidence interval (CI)1.03-1.82] and 1.52 (1.06-2.19) in White-Dutch men and women compared to White-English men and women; 2.20 (1.14-4.26) and 1.46 (0.96-2.24) in Dutch-African-Caribbean men and women compared to English-African-Caribbean men and women and 0.97 (0.74-1.27) and 1.42 (1.00-2.03) in Dutch-Indian men and women compared with their English-Indian peers, respectively. Similar patterns were also observed for some MS components, e.g. raised fasting glucose in men and central obesity in women. CONCLUSION The comparatively high prevalence of MS among Dutch ethnic groups may contribute to their high prevalence of T2D. The high levels of some MS components, e.g. raised fasting glucose in men and central obesity in women add to the high prevalence of MS in Dutch ethnic groups.

Abstract
Diabetes is a chronic condition requiring lifelong self-management. Patients are encouraged to access appropriate services to facilitate optimum management of diabetes. Although equitable access to healthcare in the United Kingdom is a legal right, not all groups and individuals in the community experience equity. Despite various equality laws and numerous efforts to minimise health inequalities related to access, particular community groups are more likely to experience inequitable access than others. The Bangladeshi community are one such community who experience some of the worst diabetes-related health outcomes in the United Kingdom. Little is known about their experiences and preferences in accessing diabetes healthcare information and services. Consequently, we undertook a scoping review of the literature by following the York Scoping Reviews Framework to identify the experiences and preferences of Bangladeshi patients and carers when gaining access to diabetes-related healthcare information and services. We identified eight articles and reported our results in relation to four domains of access: health service availability, health service utilisation, health service outcomes and the notion of equity. The review identified that language and literacy issues were the most common barriers hindering access to information and services. Patient knowledge regarding diabetes and its management was generally low, and friends and family were frequently being used as information sources and as informal interpreters. Additionally, there were feelings of isolation from mainstream information and services possibly resulting in the high prevalence of depression in the Bangladeshi community with women more affected than men. Social networks combined with religious and cultural beliefs as well as wider societal duties played a crucial role in accessing information and services for this population, and the identification of these issues merit further research and are possible avenues towards improved access to healthcare information and services for the Bangladeshi population.

Abstract
Amlodipine is a long-acting, dihydropyridine calcium antagonist now widely used for lowering of elevated blood pressure. In recent years it has been shown to be effective in reducing both blood pressure and risk of cardiovascular (CV) events when used in combination with other antihypertensive agents of different classes. Strong evidence of cardiovascular benefit has been attained for combination of amlodipine with diuretics or angiotensin converting enzyme (ACE) inhibitors in a number of high-risk CV groups, including those with established coronary artery disease, diabetes, and at risk of renal disease. Combination therapies of amlodipine with other agents eliciting renin-angiotensin-aldosterone system blockade (angiotensin II receptor blockers or renin inhibitors) have been shown to be effective blood pressure-lowering strategies, but await the results of ongoing trials for direct evidence of benefit for renal disease progression and CV morbidity and mortality.

Abstract
BACKGROUND We assessed when blood pressure (BP) and hypertension begin to rise in African-Caribbeans compared to the white population; and whether the change relates to body mass index (BMI). METHODS Secondary analysis of the cross-sectional Health Surveys for England among 22,723 participants (21,344 whites and 1,379 African-Caribbeans) adults aged ≥18 years. RESULTS The cubic spline graphs showed a crossover (African-Caribbean greater than whites) at 30-40 years in BP. Age-specific mean BP and hypertension prevalence data showed at 20-29 years African-Caribbean men were advantaged but not thereafter. There was little difference in BMI in men. African-Caribbean women had lower systolic BP (but higher prevalence of hypertension) at 20-29 years but higher BP and prevalence of hypertension thereafter. African-Caribbean women had higher BMI than white women. Regression showed an age and ethnicity interaction for systolic (0.076 mm Hg greater increase per year, P = 0.054) and diastolic BP (0.068 mm Hg greater increase per year (P = 0.009) and hypertension (OR equals 1.02, P = 0.004) in African-Caribbean men, and diastolic BP in African-Caribbean women (0.057 mm Hg greater increase per year, P = 0.017). Crossover was 28, 44, and 28 years for systolic BP, diastolic BP and hypertension in men, respectively; and 40 years for diastolic BP in women. CONCLUSIONS Clinicians should be extra vigilant about screening African-Caribbean patients from the age of 30 years. Detailed study is needed to understand the still mysterious mechanisms for this crossover.

Abstract
Background Coronary heart disease (CHD) is highly prevalent amongst the South Asian communities in Britain. The reasons for this excess CHD risk are multifactorial, but in part relate to a susceptibility to diabetes mellitus - where the aberrant metabolism of non-esterified fatty acids (NEFA) and glucose are likely to underpin vascular disease in this population. Dietary intervention is an important and first line approach to manage increased CHD risk. However, there is limited information on the impact of the South Asian diet on CHD risk. Methods/Design The Diabetes Health, Residence & Metabolism in Asians (DHRMA) study is a blinded, randomised, placebo controlled trial that analyses the efficacy of reduced glycaemic index (GI) staples of the South Asian diet, in relation to cardio-metabolic risk factors that are commonly perturbed amongst South Asian populations - primarily glucose, fatty acid and lipoprotein metabolism and central adiposity. Using a 10-week dietary intervention study, 50 healthy South Asians will be randomised to receive either a DHRMA (reduced GI) supply of chapatti (bread), stone ground, high protein wheat flour and white basmati rice (high bran, unpolished) or commercially available (leading brand) versions chapatti wheat flour and basmati rice. Volunteers will be asked to complete a 75g oral glucose tolerance test at baseline and at 10-weeks follow-up, where blood metabolites and hormones, blood pressure and anthropometry will also be assessed in a standardised manner. Discussion It is anticipated that the information collected from this study help develop healthy diet options specific (but not exclusive) for South Asian ethnic communities.

Abstract
Refined carbohydrates, such as white rice and white flour, are the mainstay of the modern Asian Indian diet, and may contribute to the rising incidence of type 2 diabetes and cardiovascular disease in this population. Prior to the 1950s, whole grains such as amaranth, barley, brown rice, millet, and sorghum were more commonly used in Asian Indian cooking. These grains and other non-Indian grains such as couscous, quinoa, and spelt are nutritionally advantageous and may be culturally acceptable carbohydrate substitutes for Asian Indians. This review focuses on practical recommendations for culturally sensitive carbohydrate modification in a modern Asian Indian diet to reduce type 2 diabetes and cardiovascular disease in this population.

Abstract
AIMS In Guadeloupe, an island in the French West Indies, diabetes has a prevalence recently reported to be 10%. Myocardial ischaemia is more frequently silent in diabetics, and needs to be screened for and monitored, once identified. This study aimed to evaluate the prevalence of silent myocardial ischaemia (SMI) in a diabetic population and to analyze its associated cardiovascular risk (CVR) factors. METHODS This was a cross-sectional study of 147 patients with associated CVR factors, defined according to the 2004 SFC/ALFEDIAM guidelines. Exercise stress tests, myocardial performance imaging and stress echocardiography were performed. Ancova and logistic regression were used in the statistical analyses. RESULTS The patients' mean age was 62 years, and 53% were male. Mean duration of diabetes was 14 years. Overall, 23.1% had SMI, and these patients more frequently had a personal history of cardiovascular disease vs those without SMI. On multivariate logistic-regression analyses, the adjusted odds ratios of SMI were significantly increased in patients with a personal history of cardiovascular disease (4.36, 95% CI: 1.36-13.96; P=0.01) and left ventricular hypertrophy (LVH) (2.46, 95% CI: 1.03-5.86; P=0.04). CONCLUSION The prevalence of SMI in our Afro-Caribbean diabetic population was 23.1%. Searching for a personal history of cardiovascular disease and LVH may help to identify patients who need to be screened for SMI.

Abstract
BACKGROUND High blood pressure is the single most important risk factor worldwide for the development of cardiovascular disease, and has been shown to affect some ethnic minority groups disproportionately. AIM To explore ethnic inequalities in blood pressure monitoring and control. METHOD Data from Lambeth DataNet was used, based on case records from GP practices in one inner-city London borough. Blood pressure monitoring and control was compared using Quality and Outcomes Framework (QOF) targets for patients with: diabetes, coronary heart disease, stroke, hypertension, and chronic kidney disease. The study controlled for age, sex, social deprivation, and clustering within GP practices. RESULTS A total of 16 613 patients met the study criteria, with 5962 categorised as black/black British. Blood pressure monitoring was similar across ethnic groups and as good, if not better, for black patients compared to white. However, marked ethnic inequalities in blood pressure control were found, with black patients significantly less likely to achieve QOF targets than their white counterparts (odds ratio [OR] 0.73; 95% confidence interval [CI] = 0.64 to 0.82). Further inequalities were revealed in blood pressure control within disease groups and ethnic subgroups. In particular, blood pressure control was poor in African patients with diabetes (OR 0.63; 95% CI = 0.50 to 0.79) and Caribbean patients with coronary heart disease (OR 0.53; 95% CI = 0.37 to 0.77) when compared with white patients. DISCUSSION While black patients with chronic conditions are equally likely to have their blood pressure monitored, their blood pressure control is consistently poorer than that of their white counterparts. This may have important implications for cardiovascular risk management in black patients.

Abstract
There is limited information on the risk of cardiovascular disease amongst the Deaf community. Given that the access of Deaf people to mainstream health promotion is likely to be hindered by language barriers, we were interested to assess the short-term impact of cardiovascular health promotion within this group. Using a pilot study we investigated changes in cardiovascular risk factors amongst Deaf people identified to be at high cardiovascular risk, who received standard health promotion by a medical team specializing in cardiovascular health promotion. The short-term impact of cardiovascular health promotion in this group did not reduce estimates of cardiovascular risk. The reasons for this are likely to relate to the design and delivery of health promotion to Deaf people, which deserves further study.
