Lipid-lowering therapy using statins in patients with cardiovascular risk in clinical practice in Thailand.

ABSTRACT: BACKGROUND:Since the release in Thailand in 2001 of the Third Guidelines by the National Cholesterol Education Program (NCEP) Expert Panel on Detection, Evaluation and Treatment of High Blood Cholesterol in Adults or the Adult Treatment Panel (ATP III), there have been no nationwide studies on the proportion of dyslipidaemic patients who have achieved the low-density lipoprotein cholesterol (LDL-C) goals. The authors therefore aimed to estimate the percentage achievement of LDL-C goals based on the modified NCEP ATP III guidelines in intermediate- to high-risk patients. METHODS:The authors conducted a hospital-based, cross-sectional, epidemiological survey. Patients (1240) were selected consecutively from 50 hospitals across Thailand. Patients were included if they had been treated with statins for at least 3?months. RESULTS:Two-thirds were female, and the mean age was 61.7±9.5?years. The median duration of statin treatment was 21?months. Half (633/ 1240) of the patients achieved the LDL-C goal levels as defined by the NCEP guidelines (51.1%, 95% CI 48.3% to 53.8%). The very-high-risk group had the lowest percentage achievement (11.6%; 95% CI 1.6% to 21.6%), compared with 54.2% (95% CI 50.9% to 57.4%) for the high-risk group and 47.0% (95% CI 41.1% to 52.8%) for the moderate-risk group. More males achieved the LDL-C goals than females (55.6% vs 48.9%; p=0.029). CONCLUSIONS:Overall, 51.1% of the patients with cardiovascular risk, on statins treatment, achieved the NCEP ATP III LDL-C goal levels.

Project description:BackgroundLipid-lowering therapy (LLT) is one of the key strategies for reducing the atherosclerotic cardiovascular disease (ASCVD) burden. However, little is known about the percentage of people in need of different LLT regimens to achieve optimal targets of low-density lipoprotein cholesterol (LDL-C), and the corresponding cost and benefit.MethodsWe conducted a simulation study based on the data from the nationwide China PEACE MPP population cohort (2015-2020), from which we included 2,904,914 participants aged 35-75 years from all the 31 provinces in mainland China. Participants were grouped based on their 10-year ASCVD risks, then entered into a Monte Carlo model which was used to perform LLT intensification simulation scenarios to achieve corresponding LDL-C goals in each risk stratification.ResultsAfter standardizing age and sex, the proportions of participants included at low, moderate, high, and very-high risk were 70.8%, 15.6%, 11.5%, and 2.1%, respectively. People who failed to achieve the corresponding LDL-C goals -8.1% at low risk, 19.6% at moderate risk, 53.2% at high risk, and 93.6% at very-high risk (either not achieving the goal or not receiving LLT)-would be in need of the LLT intensification simulation. After the use of atorvastatin 20 mg was simulated, over 99% of the population at low or moderate risk could achieve the LDL-C goals; while 11.3% at high and 24.5% at very-high risk would still require additional non-statin therapy. After the additional use of ezetimibe, there were still 4.8% at high risk and 11.3% at very-high risk in need of evolocumab; and 99% of these two groups could achieve the LDL-C goals after the use of evolocumab. Such LLT intensification with statin, ezetimibe, and evolocumab would annually cost $2.4 billion, $4.2 billion, and $24.5 billion, respectively, and prevent 264,170, 18,390, and 17,045 cardiovascular events, respectively.ConclusionsModerate-intensity statin therapy is pivotal for the attainment of optimal LDL-C goals in China, and around 10-25% of high- or very-high-risk patients would require additional non-statin agents. There is an opportunity to reduce the rising ASCVD burden in China by optimizing LLT.

Project description:ImportanceIn patients with atherosclerotic cardiovascular disease (ASCVD), guidelines recommend optimizing statin treatment, and consensus pathways suggest use of ezetimibe and proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors in patients with persistently elevated low-density lipoprotein cholesterol (LDL-C) levels despite use of statins. Recent trials have provided evidence of benefit in reduction of cardiovascular events with these agents.ObjectiveTo estimate the percentage of patients with ASCVD who would require a PCSK9 inhibitor when oral lipid-lowering therapy (LLT) is intensified first.Design, setting, and participantsThis simulation model study used a large administrative database of US medical and pharmacy claims to identify a cohort of 105 269 patients with ASCVD enrolled from January 1, 2012, through December 31, 2013, who met the inclusion criteria (database cohort). Patients were sampled with replacement (bootstrapping) to match the US epidemiologic distribution and entered into a Monte Carlo simulation (simulation cohort) that applied stepwise treatment intensification algorithms in those with LDL-C levels of at least 70 mg/dL. All patients not initially receiving a statin were given atorvastatin, 20 mg, and the following LLT intensification steps were applied: uptitration to atorvastatin, 80 mg; add-on ezetimibe therapy; add-on alirocumab therapy, 75 mg (a PCSK9 inhibitor); and uptitration to alirocumab, 150 mg. Sensitivity analyses included evolocumab as a PCSK9 inhibitor. Efficacy was estimated from published studies and incorporated patient-level variation. Data were analyzed from December 2015 to May 2017.ExposuresTreatment intensification strategies with LLT.Main outcomes and measuresUse of LLT among the population with ASCVD and distributions of LDL-C levels under various treatment intensification scenarios.ResultsInclusion criteria were met by 105 269 individuals in the database cohort (57.2% male and 42.8% female; mean [SD] age, 65.1 [12.1] years). In the simulation cohort (1 million patients; 54.8% male and 45.2% female; mean [SD] age, 66.4 [12.2] years), before treatment intensification, 51.5% used statin monotherapy and 1.7% used statins plus ezetimibe. Only 25.2% achieved an LDL-C level of less than 70 mg/dL. After treatment intensification, 99.3% could achieve an LDL-C level of less than 70 mg/dL, including 67.3% with statin monotherapy, 18.7% with statins plus ezetimibe, and 14% with add-on PCSK9 inhibitor.Conclusions and relevanceLarge gaps exist between recommendations and current practice regarding LLT in the population with ASCVD. In our model that assumes no LLT intolerance and full adherence, intensification of oral LLT could achieve an LDL-C level of less than 70 mg/dL in most patients, with only a modest percentage requiring a PCSK9 inhibitor.
