Lipid-modifying therapy and attainment of cholesterol goals in Europe: the Return on Expenditure Achieved for Lipid Therapy (REALITY) study

Cardiovascular risk management: the success of target level achievement in high- and very high-risk patients in Hungary

BACKGROUND

The management of risk factors in patients with high cardiovascular risk and its effectiveness is of paramount importance. Over the last decade, several studies have examined the achievement of cardiovascular risk factors' target levels in Europe. In the present Hungarian study, we assessed the cardiovascular risk level of participants aged 40-65 years and the success of achieving risk factors' target levels in high- and very high-risk patients. We compared these results with the results of two similar European studies.

METHODS

We conducted a cross-sectional study involving 37,778 patients aged 40-65 years from Hungary between 2019 and 2020. Cardiovascular risk levels and target values were set according to the 2016 European Guideline. Target achievement was evaluated for body mass index, waist circumference, blood pressure, total, LDL, and HDL cholesterol, triglyceride, and HbA1c (in diabetics).

RESULTS

For 37,298 patients, all the data were available to determine their cardiovascular risk category. Of these, 23.1% had high and 31.4% had very high cardiovascular risk (men: 27.1 and 39.6%, women: 20.5 and 26.1%, respectively). Achievement of the LDL-C target of 1.8 mmol/l was only 8.0% among very high-risk patients, which was significantly lower than the European average (29%). Achievement of target blood pressure among high-risk patients was better than the European average (63.4% vs. 44.7%, respectively); however, achievement was slightly lower among very high-risk patients compared with the European average (49.4% vs. 58%, respectively). The proportion of patients with type 2 diabetes who achieved a HbA1c below 7% was 57.3% in the high-risk population and 53% in the very high-risk population, which was in line with the European average success rates (58.5 and 54%, respectively). Waist circumference (< 88 cm for women and < 102 cm for men) was achieved by 29.4% of patients in the very high-risk group in our survey, which was lower than the European average of 41%.

CONCLUSIONS

The success rate of cardiovascular risk management in Hungary is lower than the European average in several parameters. Furthermore, our data highlight the poor effectiveness of obesity management in Hungary. General practice partnerships may be important sites for positive change.

Increased Cardiovascular Risk in Psoriatic Arthritis: Results From a Case-Control Monocentric Study

Background

Psoriatic arthritis (PsA) is associated with increased cardiovascular morbidity and mortality. The aims of our real-life study were to compare the prevalence of cardiovascular risk factors (CVRFs) and cardiovascular events (CVEs) among patients with PsA with a control population, to evaluate the impact of correcting factors in equations that assess cardiovascular risk (CVR) in PsA, and to determine the percentage of patients who reach the LDLc target as indicated by the European guidelines.

Methods

In this observational cross-sectional monocentric case-control study, we used a standardized procedure to systematically assess patients with PsA aged 25–85 years who met the Classification for Psoriatic Arthritis (CASPAR) criteria. Controls were extracted from the MOnitoring NAtionaL du rISque Artériel (MONALISA) study. We compared the prevalence of CVRFs, CVEs, the CVR, and the percentage of patients reaching recommended LDLc target in both populations. The CVR was first assessed using SCORE and QRISK2 equations. Then, the SCORE equation was corrected by applying a 1.5 multiplication factor, as recommended by EULAR for rheumatoid arthritis (SCORE-PsA), and the QRISK2 was corrected using the “rheumatoid arthritis” item (QRISK2-PsA).

Results

A total of 207 PsA and 414 controls were included. CVRFs and CVEs were more frequent in the PsA group. After controlling for age and gender, atherothrombotic disease was increased in the PsA population (SCORE p = 0.002, QRISK2 p = 0.001). Using the SCORE-PsA increased the percentage of patients with a high or very high CVR from 39.3 to 45.3% in the PsA group. Similarly, using the QRISK2-PsA increased the percentage of patients with a CVR ≥ 10% from 44.9 to 53.2%. The percentages of patients with PsA with high LDLc in the high and very high CVR groups were not significantly different from controls, despite a trend in favor of patients with PsA. Of the 83 PsA with a QRISK2 ≥ 10%, only 22.9% were treated with statin vs. 35.8% of the 134 controls. The QRISK2-PsA score did not alter these results.

Conclusion

In real-life, patients with PsA have a higher prevalence of CVRFs, as well as a higher prevalence of CVEs compared to the general population. The CVR is higher in the PsA population than in the controls either using the SCORE and QRISK2 equations or using the corrected SCORE- PsA and QRISK2-PsA equations.

Inclisiran in lipid management: A Literature overview and future perspectives

Primary and secondary prevention protocols aim at reducing the plasma levels of lipids - with particular reference to low-density lipoprotein cholesterol (LDL-C) plasma concentrations - in order to improve the overall survival and reduce the occurrence of major adverse cardiovascular events. The use of statins has been widely considered as the first-line approach in lipids management as they can dramatically impact on the cardiovascular risk profile of individuals. The introduction of ezetimibe and proprotein convertase subtilisin-kexin type 9 (PCSK9) inhibitors overcame the adverse effects of statins and ameliorate the achievement of the target lipids levels. Indeed, advances in therapies promote the use of specific molecules - i.e. short strands of RNA named small-interfering RNAs (siRNAs) - to suppress the transcription of genes related to lipids metabolism. Recently, the inclisiran has been developed: this is a siRNA able to block the mRNA of the PCSK9 gene. About 50% reduction in low-density lipoprotein cholesterol levels have been observed in randomized controlled trials with inclisiran. The aim of this review was to summarize the literature regarding inclisiran and its possible role in the general management of patients with lipid disorders and/or in primary/secondary prevention protocols.

Efficacy and Safety of Ezetimibe in Combination with Atorvastatin for Acute Coronary Syndrome Patients Accompanied with Type 2 Diabetes: A Single-Center, Non-randomized Cohort Study

Patients with type 2 diabetes (T2DM) and hyperlipidemia are with high risk of myocardial infarction (MI) or coronary death events. The combined use of ezetimibe and atorvastatin could improve treatment efficacy and safety. To explore the efficacy and safety of ezetimibe in combination with atorvastatin for the treatment of patients with T2DM and acute coronary syndrome (ACS). This was a non-randomized cohort study of 95 consecutive, treatment-naïve patients with T2DM and ACS treated at the Quanzhou First Hospital of Fujian Province between February 2014 and March 2016. According to the treatment strategy they selected, the patients were categorized into the atorvastatin (n = 46) and atorvastatin + ezetimibe (n = 49) groups. The patients were followed up at 2 weeks and 12 months. The primary endpoints included the incidence of adverse cardiovascular events and changed in blood lipids and high-sensitivity C-reactive protein (hs-CRP). At 12 months, serum total cholesterol (TC), triglycerides, and low-density lipoprotein cholesterol (LDL-C) levels were significantly lower, and high-density lipoprotein cholesterol (HDL-C) levels were significantly higher in the atorvastatin + ezetimibe (EZ) group than in the atorvastatin group (all p < 0.05). The LDL-C control rate at 12 months was significantly higher in the atorvastatin + EZ group compared with the atorvastatin group (p = 0.006). Seven patients in the atorvastatin group were re-hospitalized for angina pectoris, while only one patient in the atorvastatin + EZ group was re-hospitalized for angina pectoris (p = 0.02). The efficacy of atorvastatin + EZ in treating T2DM patients accompanied with ACS was significantly higher than using atorvastatin alone. This combined strategy has good safety profile, and could be recommended for clinical application.

Drug Treatment of Hyperlipidemia in Chinese Patients: Focus on the Use of Simvastatin and Ezetimibe Alone and in Combination

Elevated serum low-density lipoprotein cholesterol (LDL-C) is a major risk factor for coronary heart disease (CHD). Many guidelines recommend LDL-C as a primary treatment target, and statins represent the cornerstone of treatment for lipid management. Recently revised guidelines recommend even more intense management of LDL-C, especially in patients at moderate and high risk. However, LDL-C levels in the Chinese population differ from those in Western populations, and the benefits and safety of the maximum allowable dose of statins have yet to be determined. Furthermore, in practice, many patients do not achieve the increasingly stringent LDL-C goals. Consequently, alternative approaches to lipid management are required. Combination therapy with ezetimibe and a statin, which have complementary mechanisms of action, is more effective than statin monotherapies, even at high doses. Several clinical studies have consistently shown that combination therapy with ezetimibe and simvastatin lowers LDL-C more potently than statin monotherapies. Moreover, the safety and tolerability profile of the combination therapy appears to be similar to that of low-dose statin monotherapies. This review discusses the role of simvastatin in combination with ezetimibe in controlling dyslipidemia in Chinese patients, particularly the efficacy and safety of combination therapy in light of recently published clinical data.

Clinical and Economic Analysis of Lipid Goal Attainments in Chinese Patients with Acute Coronary Syndrome Who Received Post-Percutaneous Coronary Intervention

AIM

The recommended low-density lipoprotein cholesterol (LDL-C) levels of the guideline may be appropriate for Caucasian patients but not for other ethnic groups.

METHODS

A cohort study was conducted in Hong Kong, and acute coronary syndrome (ACS) patients who received percutaneous coronary intervention (PCI) between 2005 and 2015 were enrolled. The primary outcomes of interest were the total cost of care and cardiovascular-related cost during one-year follow-up. The cost difference by lipid goal attainments was analyzed by Poisson regression with multivariate treatment effects. The clinical outcomes achieved by lipid goal attainments in terms of major adverse cardiovascular events were analyzed by multivariate Cox regression.

RESULTS

Among the 4638 patients, 79.50%, 48.64%, and 36.14% attained the LDL-C goals of ＜2.6, ＜2.0, and ＜1.8 mmol/L for one year, respectively. Only about 16% patients achieved the ≥50% reduction from baseline. None of these lipid goals was associated with a significant reduction in the total cost of care. We only identified the clinical benefits associated with the lipid goal of ＜2.6 mmol/L. Other more stringent lipid goals seemed to bring a significant economic burden on cardiovascular-related cost, but their clinical benefits were uncertain.

CONCLUSIONS

Lowering LDL-C to achieve the guideline-recommended target levels for post-PCI ACS patients may lead to fewer cardiovascular events, but it may not necessarily lead to economic benefits within one year of follow-up.

Statin prescription strategies and atherogenic cholesterol goals attainment in Lebanese coronary artery disease patients

Background Current guidelines recommend a low-density lipoprotein cholesterol goal of <1.8 mmol/L (<70 mg/dL) and a non high-density lipoprotein cholesterol (non-HDL-C) goal of <2.6 mmol/L (<00 mg/dL) for coronary artery disease (CAD) patients. Objective This study aimed to describe real-life statin prescription strategies and to assess their effectiveness in terms of LDL-C and non-HDL-C goals attainment in a cohort of CAD patients. Setting Outpatient cardiology specialty clinics located in main Lebanese cities. Methods This is a retrospective crosssectional study. Eligible patients were those who had established CAD, treated with statins and having complete follow-up lipid panel at least 3 months from statin prescription. The following statin prescription strategies were considered in data analysis: prescription of different intensity statin as monotherapy, prescription of a statin in combination with: a low fat diet, another lipid-altering agent and another lipidaltering agent plus a low fat diet. Main outcome measure LDL-C goal attainment for each of the statin prescription strategy. Results Of the 423 CAD statin-treated patients, only 38.5 and 36.6% attained their recommended LDL-C and non-HDL-C goals, respectively. Using a statin in combination with ezetimibe or with another lipid-altering agent plus a low fat diet were significantly associated with LDL-C and non-HDL-C goals attainment. Conclusion Improvement of statin prescription strategies, such as using regular and scheduled dosage of high-intensity statins and combining statin therapy with ezetimibe, is therefore required when managing patients with CAD.

The decreased achievement of therapeutic goal in lipid lowering therapy in obese and diabetic patients in Poland

BACKGROUND

Statins are used to reduce a cardiovascular risk. However, the effectiveness of the therapy in many cases remains unsatisfactory. Therefore, the aim of this study was to evaluate the influence of obesity and diabetes on the achievement of therapeutic goal in lipid-lowering therapy in patients with a various cardiovascular risk in the daily clinical practice.

METHODS

This study was conducted on the basis of questionnaires obtained from 7018 patients (41.4% obese, 65.9% viscerally obese and 25.3% diabetics) treated with statins for at least three months. The effectiveness of the treatment was assessed in a subgroup of 3218 patients with a full lipid profile.

RESULTS

The LDL-cholesterol target, adjusted for cardiovascular risk, was obtained by 8.1% of patients, less frequently by those with a very high risk of a cardiovascular disease (3.7%), obesity (5.5%), visceral obesity (5.5%) and the type 2 diabetes (5.3%). The obese patients with type 2 diabetes were the least likely to reach the target (3.0%). Male gender, age, the body mass index (BMI)≥28kg/m², visceral obesity, type 2 diabetes, and a low/moderate statin dose prescription were independent factors decreasing the chance of reaching the low-density lipoprotein (LDL) cholesterol target.

CONCLUSIONS

1. The prescribed statin doses do not fully explain the lower frequency of achieving the recommended target in a lipid-lowering therapy in the obese patients and the diabetics. 2. In the daily clinical practice the doses of statins are frequently insufficient and not adjusted for a cardiovascular risk.

Lifestyle and risk factor management in people at high risk of cardiovascular disease. A report from the European Society of Cardiology European Action on Secondary and Primary Prevention by Intervention to Reduce Events (EUROASPIRE) IV cross-sectional survey in 14 European regions

Background European Action on Secondary and Primary Prevention by Intervention to Reduce Events (EUROASPIRE) IV in primary care was a cross-sectional survey carried out by the European Society of Cardiology, EURObservational Research Programme in 2014-2015 in 71 centres from 14 European countries. The main objective was to determine whether the 2012 Joint European Societies' guidelines on cardiovascular disease (CVD) prevention in people at high CVD risk have been followed in clinical practice. Methods Patients without a history of atherosclerotic disease started on either blood pressure and/or lipid and/or glucose-lowering treatments were identified and interviewed at least six months after the start of medication. Results Medical notes of 6700 patients were reviewed, and 4579 patients (58.7% women; mean age 58.8 (standard deviation (SD) 11.3) years) interviewed (interview rate 68.3%). Overall, 16.6% were smokers, 39.9% were overweight (body mass index (BMI)≥25 and <30 kg/m²), 43.5% obese (BMI ≥30 kg/m²) and 63.9% centrally obese (waist circumference of ≥88 cm for women, ≥102 cm for men). The medical risk factor control was very poor, with less than half (42.8%) of the patients on blood pressure lowering medication reaching the target of <140/90 mm Hg (<140/80 mm Hg in people with self-reported diabetes). Among treated dyslipidaemic patients only 32.7% attained the low-density lipoprotein (LDL)-cholesterol target of <2.5 mmol/l. Among people treated for type 2 diabetes mellitus, 58.5% achieved the glycated haemoglobin (HbA1c) target of <7.0%. Conclusion The EUROASPIRE IV survey shows that large proportions of patients at high CVD risk have unhealthy lifestyle habits and uncontrolled blood pressure, lipids and diabetes. The present data make it clear that more efforts must be taken to improve cardiovascular prevention in people at high CVD risk.

A study in high-risk, maximally pretreated patients to determine the potential use of PCSK9 inhibitors at various thresholds of total and LDL cholesterol levels

PURPOSE OF THE STUDY

Statins and ezetimibe reduce low-density lipoprotein cholesterol (LDL-c) and cardiovascular disease (CVD) risk. Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors lower LDL-c by 50%-70% and might be useful in refractory patients. The National Institute for Health and Care Excellence (NICE) technology appraisal guidance (TAG) recommends use of these drugs in secondary prevention and familial hypercholesterolaemia (FH) at differing LDL-c thresholds. We have estimated the proportion of patients in whom this third-line drug might be useful.

STUDY DESIGN

We used data from a lipid-lowering audit programme to study 72 with FH and/or CVD of 271 patients referred over 12 months who failed to achieve target total cholesterol (TC) and LDL-c levels. All 72 patients were treated with ezetimibe, and 69 cases also received statins. We used LDL-c thresholds 1.5-5.5 mmol/L to estimate how many of these refractory patients could benefit from PCSK9 inhibitors.

RESULTS

In 72 patients, TC and LDL-c targets were not met by 64 and 53 patients, respectively. We judged using the NICE TAG that only one patient (1.4% ezetimibe requiring and 0.4% total referrals) required a PCSK9 inhibitor.

CONCLUSIONS

We determined that the proportion of patients eligible for a PCSK9 inhibitor at various TC and LDL-c levels is modest. This may reflect the use of all available statins in UK lipid clinics often at non-daily frequency. We suggest that cost-effective use of PCSK9 inhibitors requires prescribing being restricted to clinicians working in specialised lipid clinics.

Statin therapy in patients with acute coronary syndrome: low-density lipoprotein cholesterol goal attainment and effect of statin potency

Background

Elevated low-density lipoprotein cholesterol (LDL-C) is associated with an increased risk of coronary artery disease. Current guidelines recommend an LDL-C target of <70 mg/dL (<1.8 mmol/L) for acute coronary syndrome (ACS) patients, and the first-line treatment to lower lipids is statin therapy. Despite current guidelines and the efficacious lipid-lowering agents available, about half of patients at very high risk, including ACS patients, fail to achieve their LDL-C goal. This study assessed LDL-C goal attainment according to use of high and low potency statins in routine practice in Thailand.

Methods

A retrospective cohort study was performed by retrieving data from medical records and the electronic hospital database for a tertiary care hospital in Thailand between 2009 and 2011. Included were ACS patients treated with statins at baseline and with follow-up of LDL-C levels. Patients were divided into high or low potency statin users, and the proportion reaching the LDL-C goal of <70 mg/dL was determined. A Cox proportional hazard model was applied to determine the relationship between statin potency and LDL-C goal attainment. Propensity score adjustment was used to control for confounding by indication.

Results

Of 396 ACS patients (60% males, mean age 64.3±11.6 years), 229 (58%) were treated with high potency statins and 167 (42%) with low potency statins. A quarter reached their target LDL-C goal (25% for patients on high potency statins and 23% on low potency statins). High potency statins were not associated with increased LDL-C goal attainment (adjusted hazards ratio 1.22, 95% confidence interval 0.79–1.88; P=0.363).

Conclusion

There was no significant effect of high potency statins on LDL-C goal attainment. Moreover, this study showed low LDL-C goal attainment for patients on either low or high potency statins. The reasons for the low LDL-C goal attainment rate warrants further investigation.

Prevalence of lipid abnormalities and attainment of normal lipid levels among patients with dyslipidaemia: a pooled analysis of observational studies from five Asian countries

AIMS

Guidelines emphasise the importance of low-density lipoprotein cholesterol (LDL-C) goals for cardiovascular risk reduction. Given the importance of association between high-density lipoprotein (HDL-C) and triglycerides (TG) normal levels and cardiovascular risk, there is an additional need to further evaluate diverse dyslipidaemic populations.

METHODS

A retrospective longitudinal observational study of patients aged ≥ 35 years on lipid-modifying therapy (LMT) for ≥ 12 months was conducted from patient records pooled from five Asian countries (Malaysia, Korea, Hong Kong, Thailand and Philippines). The prevalence of lipid abnormalities and goal attainment was assessed 12 months before and after LMT initiation.

RESULTS

Among 3256 patients (mean age - 58.6 years, 50.4% men), 65.4% were high-risk patients and 88% were on statin therapy. At baseline 94.7% of all patients had at least one abnormal lipid value elevated, LDL-C (86.2%) being the most prevalent. Non-smokers [OR (95% CI): 1.42 (1.08-1.87)], non-diabetics [2.35 (1.96-2.82)], non-cardiovascular disease patients [1.77 (1.42-2.21)] and those from Korea [2.56 (1.83-3.59)] were more likely to attain LDL-C goals. On the contrary, women [0.82 (0.68-0.98)], subjects with FRS > 20% [0.56 (0.41-0.77)] those from Malaysia [0.55 (0.39-0.77)] and the Philippines [0.18 (0.12-0.28)] were less likely to reach LDL-C goals. Fewer characteristics were independently associated with reaching normal levels of HDL-C and TG and attaining at least two normal lipid levels.

CONCLUSIONS

While current LMT reduced the prevalence of dyslipidaemia, a third of patients still failed to achieve target/normal levels. We highlight country differences and the importance of improving therapy to attain multiple lipid goals/normal levels.

Gender and ethnic differences in the control of hyperlipidaemia and other vascular risk factors: insights from the CEntralised Pan-South African survey on tHE Under-treatment of hypercholeSterolaemia (CEPHEUS SA) study

Aim

The aim of the CEntralised Pan-South African survey on tHE Under-treatment of hypercholeSterolaemia (CEPHEUS SA) was to evaluate the current use and efficacy of lipid-lowering drugs (LLDs) in urban patients of different ethnicity with hyperlipidaemia, and to identify possible patient characteristics associated with failure to achieve low-density lipoprotein cholesterol (LDL-C) targets. There is little published data on LDL-C attainment from developing countries.

Methods

The survey was conducted in 69 study centres in South Africa and recruited consecutive patients who had been prescribed LLDs for at least three months with no dose adjustment for six weeks. All patients provided written consent. One visit was scheduled for data collection, including fasting lipid and glucose, and HbA_1c levels.

Results

Of the 3 001 patients recruited, 2 996 were included in the final analyses; 1 385 subjects were of Caucasian origin (818 male), 510 of African ancestry (168 male), 481 of mixed ancestry (222 male) and 620 of Asian origin (364 male). Only 60.5% of patients on LLDs for at least three months achieved the LDL-C targets recommended by the NCEP ATP III/2004 updated NCEP ATP III guidelines and 52.3% the fourth JETF/South African guidelines. African females were on average younger than females of other ethnic origins, and had the lowest smoking rates but the highest prevalence of obesity, hypertension, the metabolic syndrome and diabetes mellitus (DM), with the worst glycaemic control. Although women were less likely than men to reach goal [OR 0.65 (CI 0.54–0.77), p < 0.001 for NCEP ATP III guidelines and OR 0.76 (CI 0.64–0.91), p < 0.003 for fourth JETF guidelines], women of African ancestry were just as likely not to reach goal as their Caucasian counterparts.

Conclusion

The results of this survey highlight the sub-optimal lipid control achieved in many South African patients, and profile important gender and ethnic differences. Control of cardiovascular disease risk factors across gender and ethnic groups remains poor.

Total and low-density lipoprotein cholesterol in high-risk patients treated with atorvastatin monotherapy in the United Kingdom: analysis of a primary-care database

OBJECTIVE

British clinical guidelines recommend statins as first-line lipid-modifying treatment (LMT) for patients at high risk of cardiovascular disease (CVD). We undertook an observational study to assess total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) levels in high-risk patients who were treated with atorvastatin monotherapy by UK general practitioners.

METHODS

This retrospective database study included patients with a prescription for atorvastatin monotherapy between November 30, 2008, and November 30, 2011, with the index date defined as the first atorvastatin prescription during this period. Eligible high-risk patients with evidence of coronary heart disease (CHD), atherosclerotic vascular disease (AVD), diabetes mellitus (DM), or familial hypercholesterolemia (FH) were required to have ≥1 TC and LDL-C measurement between 3 and 12 months after the index date, and continuous enrollment 1 year before and 1 year after the index date. Cholesterol levels were assessed using the National Institute for Health and Care Excellence (NICE) guidelines: TC <4.0 mmol/L or LDL-C <2.0 mmol/L.

RESULTS

Of 2999 high-risk patients (60.2% men; mean [SD] age = 67.9 [10.6] years) meeting selection criteria, 23.9% 28.2%, 36.2%, and 11.6% received prescriptions for atorvastatin 10, 20, 40, and 80 mg, respectively (percentages do not sum to 100 because of rounding). Across all doses, the mean (SD) follow-up TC was 4.08 (0.80) mmol/L and LDL-C 2.08 (0.65) mmol/L. A large proportion of patients (88.8%) had TC < 5.0 mmol/L. However, only 45.8% had TC < 4.0 mmol/L, and 46.5% had LDL-C < 2.0 mmol/L. Although a larger proportion of patients with CHD/AVD + DM reached guideline-recommended lipid levels, only 63.7% of such patients had TC < 4.0 or LDL-C < 2.0 mmol/L, which are the current targets for this subgroup as recommended by NICE.

CONCLUSIONS

Less than half of UK high-CVD-risk patients receiving atorvastatin monotherapy achieved guideline-recommended treatment targets for TC, and less than two-thirds of patients with CHD/AVD + DM had values below TC (4.0 mmol/L) or LDL-C (2.0 mmol/L) targets. More effective lipid-lowering strategies may be warranted to optimize cholesterol lowering and target attainment in high-risk patients. Limitations of this study include its retrospective, observational nature.

Attainment of normal lipid levels among high cardiovascular risk patients: pooled analysis of observational studies from the United Kingdom, Sweden, Spain and Canada

BACKGROUND

Although low-density lipoprotein cholesterol (LDL-C) is the primary lipid target for cardiovascular disease (CVD) risk reduction, high-density lipoprotein cholesterol (HDL-C) and triglycerides (TG) have also emerged as risk factors. This study evaluated attainment of goal/normal lipid levels in current clinical practice among high-risk patients following lipid-modifying therapy (LMT).

METHODS

Data for patients aged ≥35years and on LMT for ≥12months were identified from electronic medical records (United Kingdom and Sweden) and extracted from medical charts (Canada and Spain). High CVD risk was defined according to the Adult Treatment Panel III guidelines. An index period was defined, from January 1995-July 2008, during which patients received an initial LMT prescription. Prevalence of lipid abnormalities was assessed 12months before and after the index date. Multivariate logistic regressions evaluated predictors of attaining goal/normal lipid levels.

RESULTS

Among 12,768 high-risk patients, 75% had elevated LDL-C, 37% low HDL-C, and 30% elevated TG before LMT. Despite therapy (97% statins only), 23% had elevated LDL-C, 36% low HDL-C, 16% elevated TG, and 17% had ≥2 abnormal lipid levels. Framingham risk score >20% (Odds Ratio, 95% confidence interval: 0.37,0.31-0.43), diabetes (0.75,0.64-0.88), hypertension (1.26,1.09-1.46), current smoker (0.82,0.70-0.95) and increased body mass index (0.95,0.94-0.96) were associated with the likelihood of attaining ≥2 normal lipid levels (vs. LDL-C goal only).

CONCLUSION

Current approaches to lipid management improve LDL-C goal attainment; however, control of multiple lipid risk factors remains poor. Patients may benefit from more comprehensive approaches to lipid management, which treat multiple lipid abnormalities, as suggested in clinical guidelines.

Primary care of patients with high cardiovascular risk : Blood pressure, lipid and diabetic target levels and their achievement in Hungary

Cardiovascular diseases are responsible for the majority of premature deaths in Hungary as well. Most of them could be prevented with healthy lifestyle of patients and adequate drug prescription of primary care physicians. Earlier European surveys found wide differences between the practices and achievements of different countries in this field. The study was based on and designed according to the framework of previous European Action on Secondary and Primary Prevention by Intervention to Reduce Events (EUROASPIRE) studies and aimed presenting Hungarian results and comparing with the achievements of other countries and previous Hungarian surveys. Among rural and urban settings, 679 patients under continuous care (236 diabetics, 218 with dyslipidaemia, and 225 with hypertension) were consecutively selected by 20 experienced general practitioners. The mean age of patients was 60.3 years (men) and 64.0 years (women). Among diabetics, less than 7 % of glycated hemoglobin (HbA1c) values were found in 42.5 % patients, while only 11.4 % patients had fasting plasma sugar less than 6.0 mmol/L. Of the patients treated for dyslipidaemia, the target level of triglyceride was reached by 40.6 %, recommended total cholesterol by 14.2 % and the HDL-cholesterol by 71.8 %. The therapeutic control of total and HDL-cholesterol was better in men, although women had better triglyceride values. The achievement among patients with hypertension was 42.0 %. Significantly higher blood pressure was measured by patients who were treated with not recommended combinations of antihypertensive medication. A remarkable improvement could be observed in Hungary in the field of secondary prevention. It was greater among patients with hypertension and dyslipidaemia and smaller in diabetes care. Compared to the results of published European surveys, Hungary occupies a good position, but further improvement is still required.

Lipid goal attainment and prescription behavior in asian patients with acute coronary syndromes: experience from a tertiary hospital

Lipid goal attainment studies in Asian patients with acute coronary syndrome (ACS) are limited. The objectives of this study were to determine low-density lipoprotein cholesterol (LDL-C) goal attainment rate at 4 months, and to examine prescription behavior influencing lipid goal attainment in Asian patients with ACS. A retrospective analysis of 267 patients with ACS was performed. The mean follow-up duration was 41.2±10.7 months. LDL-C goal attainment rate was highest at 4 months (36.7%) but declined progressively throughout follow-up. More than 85% of patients were discharged with equipotent statin dose of 2 (equivalent to simvastatin 20 mg) or less. In patients who did not attain LDL-C goals, the statin dose remained low throughout follow-up because of a lack in responsive dose titration. Aggressive lipid-lowering therapy should be initiated early to improve goal attainment in these high-risk patients.

Lipid-lowering pharmacotherapy in Central and Eastern European countries in cardiovascular prevention: self-reported prescription patterns of primary care physicians

AIMS

The aims of this study were (1) to explore physicians' self-reported treatment of patients with dyslipidemia and (2) to identify intercountry differences and associations between physicians' characteristics and treatment patterns.

METHODS

A cross-sectional survey was performed in primary health care in 9 Central and Eastern European countries. An anonymous questionnaire, which included questions devoted to dyslipidemia treatment, was distributed.

RESULTS

A total of 3000 physicians were randomly chosen and 867 responded. The mean percentage of physicians in all countries who reported regular use of statins in primary prevention of cardiovascular diseases (CVD) was 86.4 (range between 91.0% of Polish physicians and 75.7% of Czech physicians; P < .01). In secondary prevention, the mean percentage was only a little higher, 89.9. The use of fibrates for primary prevention was reported by 40.3% of the respondents from Bulgaria and by 2% of the respondents from Estonia (P < .01). Also, significant differences between countries were found in the use of fibrates and combination therapy in secondary prevention. Atorvastatin and simvastatin were the most prescribed drugs in everyday practice (the mean percentage of physicians in all countries was 72.5% and 68.0%, respectively). More than three-fourth of the respondents reported prescribing lifelong treatment with statins. Inconsistent associations were found between the characteristics of physicians and their treatment patterns.

CONCLUSIONS

There are significant variations in the use of lipid-lowering drugs in Central and Eastern European countries; however, statin monotherapy predominates. Some physicians' decisions are made without supporting evidence from clinical trials. There is still scope to improve preventive care of CVD.

Treatment to lipid targets in patients with inflammatory joint diseases in a preventive cardio-rheuma clinic

OBJECTIVES

To perform cardiovascular risk stratification in patients with inflammatory joint diseases (IJD) and treat to lipid targets according to recommendations.

METHODS

We initiated a preventive cardio-rheuma clinic based on the unmet need of adequate cardiovascular prevention in IJD patients. A full cardiovascular risk stratification was performed at the first consultation (history of conventional risk factors and of cardiovascular disease, lipid measurement, blood pressure and ultrasound examination of both carotid arteries), and the patient was classified to either a primary or secondary cardiovascular prevention regime, or to have a low risk (no intervention). Lipid-lowering treatment was adjusted until at least two lipid targets were achieved.

RESULTS

Of the 426 patients referred, 36.6% had a systematic coronary risk evaluation less than 5% (no lipid-lowering intervention). The remaining 270 patients ((rheumatoid arthritis (RA), n=165; ankylosing spondylitis (AS), n=70; and psoriatic arthritis (PsA), n=35) were assigned to either primary (n=63) or secondary prevention (n=207). There were significant differences between the patient groups regarding age (p<0.001), sex (p<0.001) and disease duration (p<0.001). Lipid changes in IJD patients were: total cholesterol -1.86±1.20 mmol/l (p<0.001); low-density lipoprotein cholesterol -1.74±1.11 (p<0.001); high-density lipoprotein cholesterol 0.01±0.30 (p=0.61); triglycerides -0.28±0.72 (p<0.001). The proportions of patients reaching at least two lipid targets were for RA 92.1%, AS 90.0% and PsA 82.9%. No serious adverse events were observed.

CONCLUSIONS

There was indication for cardiovascular prevention in a high proportion of IJD patients referred for cardiovascular risk stratification. Treatment to lipid targets was successful in approximately 90% of patients with IJD.

Effectiveness of lipid-lowering therapy with statins for secondary prevention of atherosclerosis--guidelines vs. reality

BACKGROUND

The aim of the study was to analyze the effectiveness of lipid-lowering therapy and therapeutic decisions made by physicians for patients not achieving LDL targets.

METHODS

11,768 patients undergoing therapy with statins for secondary prevention of atherosclerosis participated in a two-visit survey. In subjects not achieving the LDL-target (< 100 mg/dl), further therapeutic decisions made by physicians were recorded.

RESULTS

Initially the LDL-target was achieved by 7.8% of patients on simvastatin and by 18.0% on atorvastatin, of which 20.8% were treated with at least a 40 mg dose. The most common changes in therapy to improve effectiveness was substituting simvastatin for another statin (75.2%, usually atorvastatin), or increasing atorvastatin dosage (59.8%). Intensification of a low fat diet and weight reduction were more frequently recommended in treatment with atorvastatin than with simvastatin (59.8% vs. 55.9%, p < 0.001). After enhanced therapy, the LDL-target was achieved by 27.8% on simvastatin and by 35.0% on atorvastatin (p < 0.001). In those with LDL levels remaining above the target, substitution of simvastatin with atorvastatin (49.9%), or the increase of atorvastatin dose (41.4%) was recommended. As previously, life-style counseling was more frequent in patients on atorvastatin (66.1% vs. 45.7% p < 0.001).

CONCLUSIONS

1. The use of low dose statins and noncompliance with behavioral modification guidelines are responsible for the low levels of effectiveness found with lipid-lowering therapies. 2. Physicians prefer substitution of less effective statins over the increase of dose in patients not achieving LDL targets. 3. Life-style changes are under-prescribed by physicians and under-implemented by their patients.

Effectiveness of treat-to-target strategy for LDL-cholesterol control in type 2 diabetes: post-hoc analysis of data from the MIND.IT study

BACKGROUND

The paper presents a post-hoc analysis of the intensity of dyslipidaemia care operated in the first 2 years of Multiple-Intervention-in-type-2-Diabetes.ITaly (MIND.IT) study.

DESIGN AND METHODS

MIND.IT is a multicentric, randomized, two-parallel arm trial involving 1461 type 2 diabetic patients at high cardiovascular (CV) risk. The study compares the usual care (UC) of CV prevention with a multifactorial intensive care (IC) approach aiming at achieving target values for the main CV risk factors according to a step-wise treat-to-target approach.

RESULTS

Proportion of patients on target for low-density lipoprotein cholesterol (LDL-C) was about 10% at baseline and increased significantly more with IC than UC (43 vs. 27%; p < 0.001). However, the majority (57%) of patients, in this intended intensively treated cohort, failed to achieve the proposed target. Average LDL-C decreased from 144 ± 35 to 108 ± 31 mg/dl with IC and from 142 ± 28 to 118 ± 32 with UC (p-for-interaction <0.0001). IC was associated with a significantly greater increase in statin prescription and lower withdrawal from treatment than UC (43 vs. 11% and 28 vs. 61%, respectively; both p < 0.001). However, the new treatments were characterized in both groups by the use of low starting doses (≤ 10 mg of atorvastatin, equivalent dose in more than 90% of patients) without increase in case of missed target.

CONCLUSIONS

The application of a multifactorial treat-to-target intervention is associated with a significant improvement in LDL-C beyond usual practice. However, the change in LDL-C appears to be more related to an increased number of treated patients and a decreased treatment withdrawal than to a true treat-to-target approach.

LDL-cholesterol target values and actual values in patients with type 2 diabetes (T2D) uncontrolled on oral antidiabetic monotherapy: the lipid results of the French ESCALADE survey

AIM

While new European guidelines have recommended much lower LDL-c target values than current 2005 French HAS guidelines, it appears that even those ones are not widely implemented. This lipid-side of the ESCALADE study was designed to determine the LDL-c target values of GPs, diabetologists (DIABs) and cardiologists (CARDIOs) and the consistency of actual values in patients with type 2 diabetes (T2D) uncontrolled on antidiabetic monotherapy.

METHODS

ESCALADE was a national multicentre, observational, descriptive, transversal survey. One thousand and three hundred GPs and 350 specialists (DIABs and CARDIOs) agreed to include respectively three and four patients each. For each patient, the physician had to set the LDL-c target value that was compared to the calculated HAS target value. The actual LDL-c value was recorded and compared to those target values.

RESULTS

A total of 412 GPs, 137 DIABs and 27 CARDIOs included respectively 699, 364 and 66 patients. Among them 19.6% had cardiovascular disease (CVD) and 56.9% were on lipid-lowering therapy (LLT). The physician's target value was in concordance with HAS value in 37.3% (GPs), 35.4% (DIABs) and 57.4% (CARDIOs) of the cases. Physicians overestimated the risk in respectively 42.7%, 54.1% and 21.3%. However, very high risk was underestimated in respectively 38.1%, 22.0% and 25.6% of the patients and the actual LDL-c value was in the target range (<100mg/dL) for only 28% of the very high-risk patients.

CONCLUSION

Physicians tend to overestimate the CVD risk in patients with T2D and set lower LDL-c target values than HAS calculated values. Nevertheless, patients with a very high risk are largely under-treated.

Mixed dyslipidemias in primary care patients in France

OBJECTIVE

To determine the prevalence of single and mixed dyslipidemias among patients treated with statins in clinical practice in France.

METHODS

This is a prospective, observational, cross-sectional, pharmacoepidemiologic study with a total of 2544 consecutive patients treated with a statin for at least 6 months.

MAIN OUTCOME MEASURES

Prevalence of isolated and mixed dyslipidemias of low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C), and triglycerides among all patients and among patients at high cardiovascular risk; clinical variables associated with attainment of lipid targets/normal levels in French national guidelines.

RESULTS

At least one dyslipidemia was present in 50.8% of all patients and in 71.1% of high-risk patients. Dyslipidemias of LDL-C, HDL-C, and triglycerides were present in 27.7%, 12.4%, and 28.7% of all patients, respectively, and in 51.0%, 18.2%, and 32.5% of high-risk patients, respectively. Among all subjects with any dyslipidemia, 30.9% had mixed dyslipidemias and 69.4% had low HDL-C and/or elevated triglycerides, while 30.6% had isolated elevated LDL-C; corresponding values for high-risk patients were 36.8%, 58.9%, and 41.1%. Age, gender, body mass index and Framingham Risk Score >20% were the factors significantly associated with attainment of normal levels for ≥2 lipid levels.

CONCLUSIONS

At least one dyslipidemia persisted in half of all patients and two-thirds of high cardiovascular risk patients treated with a statin. Dyslipidemias of HDL-C and/or triglycerides were as prevalent as elevated LDL-C among high cardiovascular risk patients.

Validation of the adherence evaluation of osteoporosis treatment (ADEOS) questionnaire for osteoporotic post-menopausal women

SUMMARY

We developed and validated a specific 12-item questionnaire to evaluate adherence to oral antiresorptive medication by post-menopausal osteoporotic women in everyday practice. Over the following 9 months, an index of ≤16 was associated with an increase in the risk of treatment discontinuation of 1.69 and of 2.10 for new patients who had started treatment within the previous year.

INTRODUCTION

Adherence to medication in osteoporosis is poor. The goal of this study was to develop and validate a disease-specific questionnaire to evaluate adherence to treatment of women with post-menopausal osteoporosis taking oral antiresorptive medication.

METHODS

A prototype adherence questionnaire with 45 items developed from patient interview, literature review, and physician opinion was evaluated in a sample of 350 post-menopausal women with osteoporosis treated in primary care. Item responses were matched against scores on the Morisky Medication Adherence Scale (MMAS). The most discriminant items were retained in the final questionnaire. Concurrent and predictive validity were assessed.

RESULTS

Twelve items were associated with MMAS score at a probability level of 0.05. These were retained in the final questionnaire which provided an adherence index ranging from 0 to 22. An index of ≥20 was associated with a high probability of persistence and an index ≤ 16 with a high probability of treatment discontinuation in the following 9 months.

CONCLUSIONS

The ADEOS-12 is a simple patient-reported measure to determine adherence to osteoporosis treatments with good concurrent and discriminant validity. This is the first disease-specific adherence measure to have been developed for osteoporosis.

[Therapeutic approach to dyslipidemia and goal achievement in a Spanish population with type 2 diabetes without cardiovascular disease]

OBJECTIVE

To assess the therapeutic approach and lipid goal achievement in a spanish diabetic population at high cardiovascular risk.

SUBJECTS AND METHODS

A multicenter, descriptive, cross-sectional study consecutively recruited the first 10 patients who attended the primary care office and had been seen in the 12 months prior to the study visit. Inclusion criteria were type 2 diabetes without cardiovascular disease, LDL cholesterol levels ≤160mg/dL, triglyceride levels ≤600mg/dL, and at least one of the following: retinopathy, albuminuria, current smoking, or hypertension.

RESULTS

A total of 2412 patients were evaluated (aged 61.3±8.3 years, 46.8% women, diabetes duration 8.6±7.4 years). As compared to the previous visit (8.1±5 months before), the proportion of patients who achieved LDL-C levels <100mg/dL (22.7% vs 28.6%), non-HDL-C levels <130mg/dL (27.7% vs 33.8%) and both goals (17.6% vs 22.1%) significantly increased at the time of assessment. Statins were the most widely prescribed lipid-lowering drugs (65.5%) and the lipid-lowering drug was changed from the previous visit in 38.7% of patients, drug dosage was increased in 17.3%, and another drug was added in 5%.

CONCLUSION

Use of more potent statins and higher statin doses were the most commonly used therapeutic strategies for improving control of dyslipidemia in patients with type 2 diabetes, but these changes were clearly inadequate to achieve lipid goals in most patients with type 2 diabetes.

Projected cost-effectiveness of ezetimibe/simvastatin compared with doubling the statin dose in the United Kingdom: findings from the INFORCE study

OBJECTIVE

To evaluate the incremental cost-effectiveness ratio (ICER) of switching to ezetimibe/simvastatin (Eze/Simva) compared with doubling the submaximal statin doses, in patients with acute coronary syndrome (ACS) events in the INFORCE study.

METHODS

Lifetime treatment costs and benefits were computed using a Markov model. Model inputs included each patient's cardiovascular risk factor profile and actual lipid values at baseline and 12 weeks (endpoint). Cardiovascular event and drug costs were discounted at 3.5%. Age-specific utilities were based on UK literature values and non-coronary heart disease mortality rates on the Office of National Statistics data. In the INFORCE study, 384 patients taking statins at stable doses for ≥6 weeks before hospital admission were stratified by statin dose/potency (low, medium, and high) and then randomized to doubling the statin dose or switching to Eze/Simva 10/40mg for 12 weeks.

RESULTS

The Eze/Simva group (n=195) had a higher mean baseline total cholesterol than the double-statin group (n=189). Analyses were adjusted for baseline characteristics. In the INFORCE study, Eze/Simva reduced low-density lipoprotein cholesterol (LDL-C) by ∼30% (vs. 4% with doubling statin doses) and significantly enhanced LDL-C goal attainment. In the cost-effectiveness analysis, Eze/Simva conferred 0.218 incremental discounted quality-adjusted life year (QALY) at a discounted incremental cost of £2524, for an ICER of £11,571/QALY (95% confidence interval=£8181-£18,600/QALY). The ICER was £13,552/QALY, £11,930/QALY, and £10,148/QALY in the low-, medium-, and high-potency strata, respectively.

CONCLUSIONS

Switching to Eze/Simva 10/40 mg is projected to be a cost-effective treatment (vs. double-statin) in UK patients with ACS.

Treating arteries instead of risk factors: a paradigm change in management of atherosclerosis

BACKGROUND AND PURPOSE

Until recently, atherosclerosis was thought to be inexorably progressive. Beginning in 2001 and implemented in our vascular prevention clinics by 2003, we have been treating arteries rather than risk factors. We studied the proportion of patients with plaque progression vs regression before and after this change in paradigm.

METHODS

Carotid total plaque area was measured by ultrasound at baseline and during follow-up. Before 2003, patients were treated according to consensus guidelines. After 2003, patients with plaque progression were treated more intensively, with the explicit goal of halting plaque progression or achieving regression.

RESULTS

Four thousand three-hundred seventy-eight patients had serial plaque measurements in a given year between 1997 and 2007; 47% were female. Mean age at time of referral was 60 (SD, 15); this increased steeply (from age 50 to 62 years over the first 5 years) as we focused on stroke prevention. The annual rate of plaque progression increased steeply as the clinic populations aged but then abruptly decreased after implementation of the new approach to therapy. Before 2003, approximately half the patients had plaque progression and approximately 25% had regression; by 2005, this had reversed. Changes in plasma lipids show that the differences were attributable to plaque measurement, not simply more intensive therapy for all patients. By 2007, patients with progression had lower levels of low-density lipoprotein than those with regression.

CONCLUSIONS

Treating arteries without measuring plaque would be like treating hypertension without measuring blood pressure. A clinical trial to test this approach is being designed.

Post-prandial lipid levels for assessing target goal achievement in type 2 diabetic patients taking statin

It is inconvenient to perform serum lipid analysis in fasting state in diabetic patients with drug treatment. In patients with statin treatment and Asian diet, it has not been clearly known whether non-fasting values could be used for the clinical decision making in diabetic patients. In this study, fasting and post-prandial plasma lipid profiles of hospitalized type 2 diabetic patients taking statin, were measured in whom standard diabetic breakfast in traditional Korean style were provided. In repeated-measures ANOVA, there were no significant differences among fasting, post-prandial 2 and 4 hr low-density lipoprotein (LDL) and high density lipoprotein (HDL) cholesterol values. When compared to fasting levels, both post-prandial 2 hr and 4 hr LDL cholesterol levels were misclassified as not achieved target goal only in 4% of patients. Post-prandial HDL cholesterol matched with fasting values in women, without exception. In conclusion, the fasting and post-prandial LDL and HDL cholesterol levels are not significantly different each other and can be used in the assessment of achieving target goal in type 2 diabetes taking statin after Korean diet.

Adherence to monthly and weekly oral bisphosphonates in women with osteoporosis

This primary care database survey evaluated whether osteoporotic women treated with bisphosphonates were more adherent to monthly than to weekly treatment. Both compliance (medication possession ratio [MPR]) and persistence (time to discontinuation) were superior in the monthly ibandronate treatment group. Better control of fracture risk may thus be achieved using monthly treatment regimens.

INTRODUCTION

Treatment adherence in osteoporosis is poor. The objective of this study was to evaluate whether monthly bisphosphonate treatment provided superior adherence than weekly treatment.

METHODS

We analysed medical claims from a national prescription database (Thales). All women aged >45 years receiving a first prescription of monthly ibandronate or weekly bisphosphonates in 2007 were included. Treatment adherence was monitored from initial prescription until January 2008. Compliance was measured by the MPR and persistence by the time from treatment initiation to discontinuation. Multivariate analysis was used to identify variables independently associated with adherence.

RESULTS

Twelve-month persistence rates were 47.5% for monthly ibandronate and 30.4% for weekly bisphosphonates. Compliance was significantly higher in the monthly cohort (MPR = 84.5%) than in the weekly cohort (MPR = 79.4%). After adjustment for potential confounding variables, women with monthly regimens were 37% less likely to be non-persistent (HR = 0.63 [0.56-0.72]) and presented a 5% higher mean MPR (84.5% versus 79.3%, p < 0.001) than women with weekly regimens. Other major factors associated with improved adherence were previous densitometry and calcium or vitamin D supplementation (p < 0.01).

CONCLUSIONS

Adherence to bisphosphonates may be superior for monthly treatment than for weekly treatment and may thus provide improved fracture protection.

[From lipid target values to the JUPITER study. Significance of achieving lipid levels specified by the guidelines and deficiencies in practice]

In Hungary the life expectancy have increased by 4.14 years between 1993 and 2006 and the improvement of cardiovascular mortality contributed to this with 1.85 years. Lipid lowering therapy and achievement of target lipid levels have become recently a crucial point of cardiovascular prevention. Despite the improving tendency the rate of achieving LDL-cholesterol goal is not higher than 1/3 and its main cause seems to be the fact that greater part of the physicians (56% of them in year 2007) - seeing the results with not convenient lipid levels - yield to it, do not modify the current treatment. However, there is growing evidence that the lower LDL-cholesterol level improves not only the clinical outcome but it is cost-effective as well. The most important trial performed recently using statin was the JUPITER study, in which patients with normal lipid levels and high hs-CRP level without known atherosclerotic disease were treated with 20 mg rosuvastatin or placebo. The primary endpoint (cardiovascular mortality, stroke, non fatal myocardial infarction, unstable angina and revascularization) decreased significantly by 44% and total mortality decreased by 20%. For the prevention of one primary event 23 patients for 5 years were necessary to be treated. The results raise the need for reconsidering principles and target levels of the primary prevention and warn that in the lipid lowering therapy a greater emphasis should be placed on the hs-CRP level.

Efficacy, effectiveness and real life goal attainment of statins in managing cardiovascular risk

Statins became available for the treatment of hypercholesterolemia in 1987. Multiple, well-designed, placebo-controlled, double-blind studies revealed that each 1% reduction in serum cholesterol level was associated with about 1% reduction in risk of cardiovascular events. Low-density lipoprotein (LDL) cholesterol reduction to less than 78 mg/dL may be associated with reduction of atheroma burden. Patients with high levels of high specificity C-reactive protein and having LDL cholesterol less than 3.4 mmol/L (130 mg/dL) in primary prevention settings benefited from aggressive LDL cholesterol reduction with rosuvastatin over a 2-year period. However, in real life practice, about half of patients who are prescribed statins discontinue the medication by the end of the year. Medication adherence is lower in younger patients, women, and absence of known coronary heart disease. Personal features of the prescribing physician and dispensing pharmacies also affect patients’ compliance. More studies are needed to evaluate if “compliance packets” would benefit patients in a real life situation.

EUROASPIRE III: a survey on the lifestyle, risk factors and use of cardioprotective drug therapies in coronary patients from 22 European countries

AIM

The aim of the European Action on Secondary and Primary Prevention by Intervention to Reduce Events III (EUROASPIRE III) survey was to determine whether the Joint European Societies' guidelines on cardiovascular prevention are being followed in everyday clinical practice and to describe the lifestyle, risk factor and therapeutic management in patients with coronary heart disease (CHD) in Europe.

METHODS

The EUROASPIRE III survey was carried out in 2006-2007 in 76 centres from selected geographical areas in 22 countries in Europe. Consecutive patients, with a clinical diagnosis of CHD, were identified retrospectively and then followed up, interviewed and examined at least 6 months after their coronary event.

RESULTS

Thirteen thousand nine hundred and thirty-five medical records (27% women) were reviewed and 8966 patients were interviewed. At interview, 17% of patients smoked cigarettes, 35% were obese and 53% centrally obese, 56% had a blood pressure >or=140/90 mmHg (>or=130/80 in people with diabetes mellitus), 51% had a serum total cholesterol >or=4.5 mmol/l and 25% reported a history of diabetes of whom 10% had a fasting plasma glucose less than 6.1 mmol/l and 35% a glycated haemoglobin A1c less than 6.5%. The use of cardioprotective medication was: antiplatelets 91%; beta-blockers 80%; angiotensin-converting enzyme inhibitors/angiotensin-receptor blockers 71%; calcium channel blockers 25% and statins 78%.

CONCLUSION

The EUROASPIRE III survey shows that large proportions of coronary patients do not achieve the lifestyle, risk factor and therapeutic targets for cardiovascular disease prevention. Wide variations in risk factor prevalences and the use of cardioprotective drug therapies exist between countries. There is still considerable potential throughout Europe to raise standards of preventive care in order to reduce the risk of recurrent disease and death in patients with CHD.

[Durability of the effects of a quality improvement intervention in hypertensive patients on long-term follow-up (CICLO-RISK study)]

OBJECTIVE

To evaluate the durability of the effects achieved with a quality improvement intervention on cardiovascular risk factors and cardiovascular risk, as intermediate outcomes, in hypertensive patients on long-term follow-up long time primary health care.

DESIGN

Quasi-experimental study.

SETTING

Two urban primary care health centres.

PARTICIPANTS

The study included 419 and 430 hypertensive patients in the intervention (IG) and control group (CG), respectively.

INTERVENTIONS

Quality improvement intervention consisted of a combined program including, an audit, feedback, training sessions on the main cardiovascular risk factors clinical guidelines.

MEASUREMENTS

Evaluation of intermediate outcomes (blood pressure, LDL-cholesterol, HbA(1c), smoking, BMI and cardiovascular risk), were measured in both groups in March 2002, 2004 and 2006.

RESULTS

The mean of the durability effect (differences between IG and CG means) was: systolic blood pressure decreased from 8.9 to 4.3 and the diastolic from 3.9 to 2.3 mmHg (p<0.05). LDL-cholesterol decreased from 10 to 1.1mg/dl (p>0.05). Coronary risk fell from 2 to 1.2 percentage points and cardiovascular mortality risk from 0.6 to 0.4 percentage points (p<0.05). The percentage of patients with blood pressure<140/90 mmHg and BMI<30 lost statistical significance in the end evaluation and only remains in the percentage of patients with coronary risk less than 20% in the 2004 and 2006 results.

CONCLUSIONS

Quality improvement intervention was associated with reductions in cardiovascular risk factors and cardiovascular risk in post intervention evaluations with a tendency to decrease the effect achieved in the end evaluation.

Relationship between compliance and persistence with osteoporosis medications and fracture risk in primary health care in France: a retrospective case-control analysis

BACKGROUND

Nonadherence to treatment is an important determinant of long-term outcomes in women with osteoporosis.

OBJECTIVES

This study was conducted to investigate the association between adherence and osteoporotic fracture risk and to identify optimal thresholds for good compliance and persistence. A secondary objective was to perform a preliminary evaluation of the cost consequences of adherence.

METHOD

This was a retrospective case-control analysis. Data were derived from the Thales prescription database, which contains information on >1.6 million patients in the primary health care setting in France. Cases were women aged >or=50 years who had an osteoporosis-related fracture in 2006. For each case, 5 matched controls were randomly selected. Both compliance and persistence aspects of treatment adherence were examined. Compliance was estimated based on the medication possession ratio (MPR). Persistence was calculated as the time from the initial filling of a prescription for osteoporosis medication until its discontinuation.

RESULTS

The mean (SD) MPR was lower in cases compared with controls (58.8% [34.7%] vs 72.1% [28.8%], respectively; P < 0.001). Cases were more likely than controls to discontinue osteoporosis treatment (50.0% vs 25.3%; P < 0.001), yielding a significantly lower proportion of patients who were still persistent at 1 year (34.1% vs 40.9%; P < 0.001). MPR was the best predictor of fracture risk, with an area under the receiver-operating-characteristic curve that was higher than that for persistence (0.59 vs 0.55). The optimal MPR threshold for predicting fracture risk was >or=68.0%. Compared with less-compliant women, women who achieved this threshold had a 51% reduction in fracture risk. The difference in annual drug expenditure between women achieving this threshold and those who did not was approximately euro300. The optimal threshold for persistence with therapy was at least 6 months. Attaining this threshold was associated with a 28% reduction in fracture risk compared with less-persistent women.

CONCLUSIONS

In this study, better treatment adherence was associated with a greater reduction in fracture risk. Compliance appeared to predict fracture risk better than did persistence.

Perspectives on low-density lipoprotein cholesterol goal achievement

BACKGROUND

Elevated levels of low-density lipoprotein cholesterol (LDL-C) are associated with an increased risk of coronary heart disease (CHD). European and US guidelines now recommend lower LDL-C levels, particularly in high-risk patients. Although LDL-C treatment goals to reduce the risk of CHD are clear, many patients do not reach their LDL-C goals.

OBJECTIVES

Examine consensus guideline targets for LDL-C lowering in patients at high or very high cardiovascular risk; examine cholesterol goal achievement in clinical practice; evaluate the effectiveness of ezetimibe/statin and other adjunctive lipid-lowering treatments in achieving LDL-C goals; and consider ongoing controversies and the randomized controlled trials that may help to resolve or better illuminate them.

METHODS

An English-language PubMed search was conducted to identify prospective randomized controlled trials, open-label studies, and retrospective and observational studies from 2001 (same year that the executive summary of the National Cholesterol Education Program's Adult Treatment Panel III was published) to present for an analysis of the effects of adjunctive therapies on LDL-C lowering and goal attainment in patients at elevated cardiovascular risk.

RESULTS

Elevated LDL-C is the primary target of lipid-lowering therapy; aggressive lowering is of great benefit to those at high risk. Statins are recommended first-line lipid-lowering agents, with a long, well-regarded history of efficacy and safety. Not all patients, however, can achieve recommended LDL-C goals simply using starting doses of statins. For such patients, more intensive therapy utilizing high-dose statins or combination therapy, including statins combined with other lipid-lowering agents, such as ezetimibe, bile acid resins (BARs), or niacin, is warranted. Potential limitations of the present review include possible publication bias and the focus on pharmacotherapy rather than lifestyle modification and the important objective of multiple risk-factor modification to reduce absolute global cardiovascular risk.

CONCLUSIONS

With a well-established link between elevated LDL-C and cardiovascular risk, aggressive LDL-C lowering becomes particularly important. Patients needing intensive LDL-C lowering to achieve goals will often require adjunctive treatments, including ezetimibe, BARs, or niacin along with statins. Given both their high mg: mg potency in lowering LDL-C and favorable tolerability and patient acceptance/adherence profile, ezetimibe/statin combination regimens arguably provide the greatest likelihood for patients to reach new, lower LDL-C targets; however, efficacy and safety data of any adjunctive treatment, along with drug costs and patient adherence to treatment (partly related to complexity of the regimen) all need to be considered when determining the optimal regimen to achieve LDL-C goals in individual patients according to their baseline absolute cardiovascular risk, LDL-C level, and consensus LDL-C targets.

[A change of attitude in lipidology, achievement of target levels. What comes next?]

One of the greatest challenges of cardiovascular prevention is to minimize the risk of cardiovascular events through the achievement of target lipid levels. Its importance is suggested by the comprehensive meta-analyses of large scale clinical trials and the therapeutic guidelines determining everyday clinical practice. The attainment of target levels is often emphasized, nevertheless, there is a gap between theory and practice. The authors compare the goal attainment rate based on Hungarian medical literature and their own data, and analyze the possibilities of further improvement. The CEL Program evaluated the achievement rate of target total cholesterol levels in more than 10 000 patients of general practitioners in 2004, 2005 and 2006, and the ratio increased from 12% to 30% within 3 years. According to the results of the Hungarian REALITY study the rate of patients achieving the target total cholesterol levels was 21% in 2004, and it increased to 27% during a 3-year period. To this very low improving rate also belongs the fact that in 2007, when only one fourth of patients were on target levels, 87% of general practitioners and 56% of specialists reconciled themselves to it and did not propose any modification in the therapy of patients not achieving the target levels. The surveys conducted at the department of internal medicine with cardiological profile of the county hospital in Gyula proved a considerable increase in the last 7 years in the administration of drugs improving the life expectancy of cardiovascular patients (aspirin, beta-blockers, ACE-inhibitors and statins) due to the widespread application of clinical guidelines and the special attention; nowadays the administration rate is above 90% in all four groups. Nevertheless, the rate of patients achieving the LDL-cholesterol goals was 37% in the high risk and 18% in the very high risk groups in December 2007 and January 2008. The fact that in the latter group only 21% of patients received combination therapy indicates that improving this ratio may be the next step. A greater emphasis should be placed on the achievement of target levels and regular revision of applied medical therapy, particularly in the high and very high risk patients as these groups can benefit the most from it.

LDL-C reductions and goal attainment among naive statin users in the Netherlands: real life results

OBJECTIVE

The effectiveness of statin therapy in a real life setting may differ from that in clinical trials, as physicians make non-randomised treatment decisions for patients with less uniform and possibly different characteristics. We therefore performed a study to compare the effectiveness of different statins and doses in routine clinical practice with respect to total serum cholesterol and LDL-cholesterol (LDL-C) reduction and goal attainment according to European guidelines on the prevention of cardiovascular disease (CVD).

RESEARCH DESIGN AND METHODS

Naive statin users starting treatment in 2003 and 2004 with LDL-C measurements at baseline and between 30 and 365 days after start of treatment were extracted from the PHARMO database. During treatment with their initial statin dose LDL-C reduction and attainment of cholesterol goals were compared between different statins and doses.

RESULTS

Of 2303 identified naive patients, approximately 30% were allocated to the high CVD-risk group. Average LDL-C reductions were 48%, 42%, 39%, and 32% at mean doses of 11 mg rosuvastatin, 17 mg atorvastatin, 22 mg simvastatin and 35 mg pravastatin, respectively. The proportion of patients attaining cholesterol goals was 75% for rosuvastatin, 68% for atorvastatin, 56% for simvastatin, and 42% for pravastatin. Dose comparisons showed greater LDL-C reduction and increased goal attainment for rosuvastatin 10 mg compared to other statins at most doses (adjusted p < 0.05).

CONCLUSIONS

In a real life setting, both LDL-C reduction and the proportion of patients attaining cholesterol goals appear to be significantly increased among users of rosuvastatin compared to other statins. These results confirm and extend reported clinical trial results to a real world setting.

Current status of cholesterol goal attainment after statin therapy among patients with hypercholesterolemia in Asian countries and region: the Return on Expenditure Achieved for Lipid Therapy in Asia (REALITY-Asia) study

BACKGROUND

Data on achieving National Cholesterol Education Program Adult Treatment Panel III (ATP III) goals in Asia are limited.

OBJECTIVE

To examine treatment patterns, goal attainment, and factors influencing treatment among patients in 6 Asian countries who were taking statins.

METHODS

A retrospective cohort study was conducted in China, Korea, Malaysia, Singapore, Taiwan, and Thailand, where 437 physicians (41% cardiologists) recruited adults with hypercholesterolemia newly initiated on statin monotherapy.

RESULTS

Of 2622 patients meeting inclusion and exclusion criteria, approximately 66% had coronary heart disease (CHD)/diabetes mellitus, 24% had no CHD but > or =2 risk factors, and 10% had no CHD and <2 risk factors. Most patients ( approximately 90%) received statins at medium or lower equipotency doses. Across all cardiovascular risk categories, 48% of patients attained ATP III targets for low-density lipoprotein cholesterol (LDL-C), including 38% of those with CHD/diabetes (goal: <100 mg/dL), 62% of those without CHD but with > or =2 risk factors (goal: <130 mg/dL), and 81% of those without CHD and <2 risk factors (goal: <160 mg/dL). Most patients who achieved goals did so within the first 3 months. Increasing age (odds ratio (OR)=1.015 per 1-year increment; 95% confidence interval (CI)=1.005-1.206; p=0.0038) and initial statin potency (OR=2.253; 95% CI=1.364-3.722; p=0.0015) were directly associated with goal attainment, whereas increased cardiovascular risk (OR=0.085; 95% CI=0.053-0.134; p<0.0001 for CHD/diabetes mellitus at baseline compared with <2 risk factors,) and baseline LDL-C (OR=0.990; 95% CI=0.987-0.993); p<0.0001 per 1-mg/dL increment) were inversely associated with LDL-C goal achievement. Limitations of this study include potential differences in treatment settings and cardiovascular risk factors between different countries and centers. In addition, the effects on cholesterol goal achievement of concomitant changes in lifestyle were not assessed.

CONCLUSION

LDL-C goal attainment is low in Asians, particularly those with CHD/diabetes. More effective patient monitoring, treatments, including combining regimens and dose titration, and adherence to these treatments along with therapeutic lifestyle counseling may facilitate goal attainment.

Achieving Vascular Risk Factor Targets: A Survey of a London General Practice

We assessed lipid goal achievement in patients at high risk for vascular events from a general practice (London, United Kingdom). Patients were identified as those with a prescription for hypolipidaemic medication, a significant (>20%) Framingham risk, and from the myocardial infarction register. Two hundred forty-five patients were currently taking a statin (average dose, 23.1 mg/day). Cholesterol, high-density lipoprotein—cholesterol, low-density lipoprotein—cholesterol, and triglycerides changed significantly following statin treatment. Of 285 patients who had taken statins at some time point, 11 (3.9%) were intolerant, 5 of which subsequently tolerated another statin. Approximately 10.1% of patients discontinued statin treatment for unclear reasons. Only 64 patients (29.1% of 220) reached the Joint British Societies' Guidelines on Prevention of Cardiovascular Disease target of a total cholesterol of <4.0 mmol/L; 50 patients (38.8% of 129) reached the low-density lipoprotein—cholesterol target of <2.0 mmol/L. This value of low-density lipoprotein—cholesterol is similar to that recommended by the American Heart Association/American College of Cardiology. With regard to the General Medical Services guidelines target for total cholesterol, 162 (73.6% of 220) patients reached ≤5.0 mmol/L. The group that best achieved target cholesterol (Joint British Societies' Guidelines and General Medical Services) were those with comorbidities. In conclusion, while reaching General Medical Services targets was satisfactory, the percentage of patients reaching Joint British Societies' Guidelines targets was not. This discrepancy may reflect the presence of multiple guidelines. The current stricter lipid targets are difficult to achieve; possible methods that may be used to improve lipids further could involve using combination therapy, statin dose titration, and better education.

Cholesterol goal attainment in patients with coronary heart disease and elevated coronary risk: results of the Hong Kong hospital audit study

OBJECTIVE

We sought to determine 1) long-term lipid-lowering treatment patterns; 2) cholesterol goal attainment rates and possible determinants of goal achievement; and 3) effects of cholesterol goal attainment on coronary events in hospitalized Hong Kong patients.

METHODS

In this retrospective cohort analysis, records of two public Hong Kong hospitals were reviewed for 196 adults (69% with coronary heart disease (CHD) or CHD-risk equivalent) who received at least one lipid-lowering therapy during hospitalization. Low-density lipoprotein cholesterol (LDL-C) targets were <2.6 mmol/l (<100 mg/dL) for patients with CHD or CHD risk equivalents and <3.37 mmol/l (<130 mg/dL) for those without.

RESULTS

Most participants were initiated on regimens of low to midequipotency doses and never had their regimens adjusted to higher potency. Approximately 44% of patients not at LDL-C at baseline failed to achieve goal during a median follow-up of 1.9 years. Patients with higher coronary risk and/or LDL-C levels at baseline were less likely than their lower-risk counterparts to achieve goal; for each 1-mmol/l (38.7-mg/dL) increase in LDL-C at baseline, the likelihood of attaining goal declined by 64%. Patients achieving cholesterol goal had significantly longer cardiovascular event-free times.

CONCLUSIONS

A total of 44% of Hong Kong patients not at LDL-C goals at baseline did not achieve them over 1.9 years. More effective and well-tolerated therapies, including adjunctive regimens (e.g., ezetimibe-statin, niacin-statin), may be necessary to enhance LDL-C goal achievement and increase event-free time.
