294 Implementation time of a lipid lowering therapy in patients with dyslipidemia: results of Prysme study

Despite the availability of specific guidelines, the management of dyslipidemia in practice is not optimal.Objective and methodologyPRYSME, a non-interventional multicentre study carried out with 1226 general practitioners, aimed to describe the implementation time of a lipid lowering treatment according to cardiovascular risk level (primary objective) and to identify its determinants. Were eligible patients treated for a dyslipidemia diagnosed less than 2 years ago. Demographic and clinical characteristics and circumstances of diagnosis and treatment initiation were collected.Results3268 patients were included (mean age: 57 years old, males: 64%). 26% were obese and 45% overweight. Only 12% had no cardiovascular risk factors (CRF) at the time of dyslipidemia diagnosis. The most frequent CRF were arterial hypertension (50%), smoking (43%), family history of premature coronary heart disease (28%), HDL-c <0.4g/l (20%) whereas 15% of the patients had a personal history of cardiovascular disease. Dietary programs were initially implemented for 98% of the patients. More than 90% were treated with a statin. The implementation time of the treatment (evaluated according to the biological confirmation of dyslipidemia), according to the initial number of CRF, was as following:0 CRF1 CRF2 CRF≥ 3 CRFSecondary preventionTotal[-3;0] months34.3%28.6%27.1%29.3%49.1%33.1%]0;3] months23.1%26.2%26.4%24.0%21.9%23.9%> 3 months42.6%45.3%46.5%46.8%29.0%43.0%Chi-2 test : P<0.001The main determinant of an early implementation of a lipid lowering therapy (≤ 3 months) was secondary prevention (OR=1.8). The number of CRF had no significant impact.ConclusionThis study underlines the lack of awareness towards cardiovascular risk factors in the management of dyslipidemia, particularly while considering the implementation time of a lipid lowering therapy

0191: Poor achievement of low-density lipoprotein cholesterol targets in French patients with stable coronary heart disease. Contemporary data from DYSIS II CHD study

AimWe sought to determine achievement of lipid targets according to current European guidelines (low-density lipoprotein cholesterol [LDL-C]≤70mg/dL) in patients with stable coronary heart disease (CHD) with or without lipid-lowering therapy (LLT), in the French cohort of the Dyslipidemia International Study IICHD (DYSIS IICHD).MethodsDYSIS IICHD was a multicentre observational cross-sectional study conducted from July 2013 to October 2014 in 27 centres in France. Adults with stable CHD (defined as≥1 of the following:>50% stenosis on coronary angiography or computed tomography, prior percutaneous coronary intervention, prior coronary bypass graft, history of ACS>3 months previously) and a fasting lipid profile done within the previous 12 months were consecutively enrolled. Eligible patients had to be on LLT for≥3 months or taking no LLT.ResultsA total of 436 CHD patients were enrolled. Of the 424 patients (97.2%) on LLT, 91.5% were on statin treatment at the moment of inclusion (mean±SD dose calculated in atorvastatin 27±23mg/day). Non-statin LLT was used in 17.7% patients (79.2% were on a cholesterol-absorption inhibitor). Mean±SD LDL-C was 87.4±30.5mg/dL, 28.4% achieved LDL-C<70mg/dL, and 67.7% had an LDL-C<100mg/dL (Table).Abstract 0191 – Table: Characteristics of lipid values in patients with stable CHDAll patients (n=436)LLT (n=424)No LLT (n=12)Age (years)69±1269±1274±12Men80.079.791.7ACS>3 months previously70.070.066.7Diabetes type 227.027.316.7Chronic kidney disease5.05.20Lipid variablesLDL-C (mg/dL)87.4±30.586.0±29.6135.3±24.5**LDL<70mg/dL28.429.20*Distance to target of<70mg/dL (mg/dL)31.1±24.229.7±23.265.3±24.5**LDL<100mg/dL67.769.38.3**Data are mean±SD or %.*P<0.05**P?0.0001 (LLT vs no LLT)ConclusionsThese observational data from contemporary clinical practice in France indicate suboptimal lipid control, with over two-thirds of high-risk CHD patients failing to achieve the LDL-C target despite taking LLT, and a large difference between mean value and target LDL-C. More-intensive treatment is required to optimize achievement of lipid goals in CHD

0188: Suboptimal control of low-density lipoprotein cholesterol in French patients after an acute coronary syndrome. Contemporary data from DYSIS IIACS study

AimTo document low-density lipoprotein cholesterol (LDL-C) values during hospitalization of ACS patients with/without lipid-lowering therapy (LLT) at admission, and achievement of the ESC LDL-C target (LDL-C≤70mg/dL) at 4 months following the acute event using data from the French cohort of the DYSIS IIACS study.MethodsDYSIS IIACS was a multicentre prospective observational cohort study (recruitment: Oct 2013 to Oct 2014) conducted in 24 coronary care units in France. Adults hospitalized for an ACS event and who had a lipid panel measured within 24 hours of admission were consecutively enrolled. Eligible patients had to be on LLT for≥3 months or taking no LLT. A telephone follow-up interview was carried out with patients (or their next of kin) 120±15 days after the index event.ResultsOf the 468 patients enrolled, 50.6% had ST-elevation myocardial infarction/left bundle branch block, 40.8% had non-ST-elevation myocardial infarction, and 8.5% had unstable angina. Of the 277 (59.2%) patients on LLT at admission, 25.3% had an LDL-C<70mg/dl (Table). Most patients (96.4%) were on statin therapy at discharge (mean+SD dose calculated in atorvastatin 49±28mg/day). Non-statin LLT was used in 5.6% patients at discharge (61.5% with a cholesterol-absorption inhibitor). At 120 days after admission, 50.9% of ACS patients with follow-up data had achieved the LDL-C target.ConclusionsThese observational data from contemporary French clinical practice in coronary care units indicate suboptimal LDL-C control, with a substantial proportion of very high cardiovascular risk patients presenting with elevated LDL-C despite taking LLT. Four months after the acute event, half of the patients (with data) failed to achieve the target, with a large difference between mean value and target LDL-C.Abstract 0188 – Table: Characteristics of and lipid values in ACS patients: during hospitalization and at 120 daysAll patients (n=468)LLT at admission (n=277)No LLT at admission (n=191)Age (years)65±1267±1261±12***Men80.178.083.2Diabetes type 221.827.413.6**Chronic kidney disease3.84.03.7Lipid variables (within 24 h of admission)LDL-C (mg/dL)110.6±43.493.6±36.4135.3±40.9***LDL<70mg/dL (%)16.925.34.7***Difference between mean and target values (mg/dL)52.1±38.337.0±32.169.3±37.5***Statin at hospital discharge96.497.594.8Lipid variables (120 days after admission)(n=159)(n=86)(n=73)LDL-C (mg/dL)76.1±31.179.7±31.171.9±30.7*LDL-C<70mg/dL50.941.961.6*Difference between mean and target values (mg/dL)29.7±25.828.0±26.532.6±24.7Data are mean±SD or %.*P<0.05**P?0.001**P?0.0001 (LLT vs no LLT

Prevalence Of Potential Familial Hypercholesteremia (Fh) In 54,811 Statin-Treated Patients In Clinical Practice

Background and aims: Familial hypercholesterolemia (FH) is a life-threatening disease, characterized by elevated LDL-C levels and a premature, increased risk of coronary heart disease (CHD) that is globally underdiagnosed. The percentage of patients with possible or probable FH in various countries was examined in the Dyslipidemia International Study (DYSIS). Methods: DYSIS is a multinational, cross-sectional observational study of 54,811 adult outpatients treated with statin therapy. The percentages of patients with high levels of LDL-C, and with possible or probable FH, were assessed using the Dutch scoring method for FH across 29 countries, in age subgroups for the analysis population and among diabetes patients. Results: Despite statin therapy, 16.1% (range 4.4-27.6%) of patients had LDL-C > 3.6 mmol/L (140 mg/dL) across countries and the prevalence of possible FH was 15.0% (range 5.5-27.8%) and 1.1% (range 0.0-5.4%) for probable FH. The highest percentages of probable FH occurred in Egypt (5.4%), the Baltic states (4.2%), Russia (3.2%), and Slovenia (3.1%), with the lowest rates in Israel (0.0%), Canada (0.2%), and Sweden (0.3%). Rates of FH were the highest in younger patients (45-54 years) for secondary prevention, regardless of the presence/absence of diabetes. Conclusions: Despite statin therapy, high LDL-C levels and rates of possible and probable FH were observed in some countries. The prevalence of FH was the highest in younger age patients, and > 60% of patients with probable FH displayed CHD. Earlier diagnosis and treatment of patients with FH are needed to reduce CHD risk in these patients. (C) 2016 The Authors. Published by Elsevier Ireland Ltd

Association Between Cardiac Radiation Exposure and the Risk of Arrhythmia in Breast Cancer Patients Treated With Radiotherapy:A Case-Control Study

Background: Previous studies suggested that radiation therapy (RT) for breast cancer (BC) can induce cardiac arrhythmias and conduction disorders. However, the association with mean heart dose and specific cardiac substructures doses was less studied. Materials and Methods: We conducted a nested case-control study based on French BC patients, enrolled in the European MEDIRAD-BRACE study (https://clinicaltrials.gov, Identifier: NCT03211442), who underwent three-dimensional conformal radiation therapy (3D-CRT) between 2009 and 2013 and were retrospectively followed until 2019. Cases were incident cases of cardiac arrhythmia. Controls without arrhythmia were selected with propensity-scored matching by age, duration of follow-up, chemotherapy, hypertension, and diabetes (ratio 1:4 or 5). Doses to the whole heart (WH), left and right atria (LA and RA), and left and right ventricles (LV and RV) were obtained after delineation with multi-atlas-based automatic segmentation. Results: The study included 116 patients (21 cases and 95 controls). Mean age at RT was 64 ± 10 years, mean follow-up was 7.0 ± 1.3 years, and mean interval from RT to arrhythmia was 4.3 ± 2.1 years. None of the results on association between arrhythmia and cardiac doses reached statistical significance. However, the proportion of right-sided BC was higher among patients with arrhythmia than among controls (57% vs. 51%, OR = 1.18, p = 0.73). Neither mean WH dose, nor LV, RV, and LA doses were associated with an increased risk of arrhythmia (OR = 1.00, p > 0.90). In contrast, the RA dose was slightly higher for cases compared to controls [interquartile range (0.61-1.46 Gy) vs. (0.49-1.31 Gy), p = 0.44], and a non-significant trend toward a potentially higher risk of arrhythmia with increasing RA dose was observed (OR = 1.19, p = 0.60). Subanalysis according to BC laterality showed that the association with RA dose was reinforced specifically for left-sided BC (OR = 1.76, p = 0.75), while for right-sided BC, the ratio of mean RA/WH doses may better predict arrhythmia (OR = 2.39, p = 0.35). Conclusion: Despite non-significant results, our exploratory investigation on BC patients treated with RT is the first study to suggest that right-sided BC patients and the right atrium irradiation may require special attention regarding the risk of cardiac arrhythmia and conduction disorders. Further studies are needed to expand on this topic

Determinants of social inequalities in stroke incidence across Europe:a collaborative analysis of 126 635 individuals from 48 cohort studies

Knowledge on the origins of the social gradient in stroke incidence in different populations is limited. This study aims to estimate the burden of educational class inequalities in stroke incidence and to assess the contribution of risk factors in determining these inequalities across Europe

Combined Influence of Waist and Hip Circumference on Risk of Death in a Large Cohort of European and Australian Adults

Background - Waist circumference and hip circumference are both strongly associated with risk of death; however, their joint association has rarely been investigated. Methods and Results - The MONICA Risk, Genetics, Archiving, and Monograph (MORGAM) Project was conducted in 30 cohorts from 11 countries; 90 487 men and women, aged 30 to 74 years, predominantly white, with no history of cardiovascular disease, were recruited in 1986 to 2010 and followed up for up to 24 years. Hazard ratios were estimated using sex‐specific Cox models, stratified by cohort, with age as the time scale. Models included baseline categorical obesity measures, age, total and high‐density lipoprotein cholesterol, systolic blood pressure, antihypertensive drugs, smoking, and diabetes mellitus. A total of 9105 all‐cause deaths were recorded during a median follow‐up of 10 years. Hazard ratios for all‐cause death presented J‐ or U‐shaped associations with most obesity measures. With waist and hip circumference included in the same model, for all hip sizes, having a smaller waist was strongly associated with lower risk of death, except for men with the smallest hips. In addition, among those with smaller waists, hip size was strongly negatively associated with risk of death, with ≈20% more people identified as being at increased risk compared with waist circumference alone. Conclusions - A more complex relationship between hip circumference, waist circumference, and risk of death is revealed when both measures are considered simultaneously. This is particularly true for individuals with smaller waists, where having larger hips was protective. Considering both waist and hip circumference in the clinical setting could help to best identify those at increased risk of death

Lack of association between serological evidence of past Coxiella burnetii infection and incident ischaemic heart disease: nested case-control study

BACKGROUND: Coxiella burnetii causes the common worldwide zoonotic infection, Q fever. It has been previously suggested that patients who had recovered from acute Q fever (whether symptomatic or otherwise) may be at increased risk of ischaemic heart disease. We undertook this study to determine if past infection with Coxiella burnetii, the aetiological agent of Q fever, is a risk factor for the subsequent development of ischaemic heart disease. METHODS: A nested case-control study within the Prospective Epidemiological Study of Myocardial Infarction (PRIME). The PRIME study is a cohort study of 10,593 middle-aged men undertaken in France and Northern Ireland in the 1990s. A total of 335 incident cases of ischaemic heart disease (IHD) were identified and each case was matched to 2 IHD free controls. Q fever seropositivity was determined using a commercial IgG ELISA method. RESULTS: Seroprevalence of Q fever in the controls from Northern Ireland and France were 7.8% and 9.0% respectively. No association was seen between seropositivity and age, smoking, lipid levels, or inflammatory markers. The unadjusted odds ratio (95% CI) for Q fever seropositivity in cases compared to controls was 0.95 (0.59, 1.57). The relationship was substantially unaltered following adjustment for cardiovascular risk factors and potential confounders. CONCLUSION: Serological evidence of past infection with C. burnetii was not found to be associated with an increased risk of IHD
