Achieving recommended low density lipoprotein cholesterol goals and the factors associated with target achievement of hypercholesterolemia patients with rosuvastatin in primary care

Relationship between Dietary Habits and Control of Lipid Profiles in Patients with Dyslipidemia Using Pravastatin

We investigated the association between dietary habits, evaluated using the modified Mini Dietary Assessment Index for Koreans (MDA), and lipid control among patients aged ≥20 years who had used pravastatin for dyslipidemia for 6 months. Participants were administered questionnaires regarding sociodemographic characteristics and lifestyle factors. Odds ratios and 95% confidence intervals for the control of low-density lipoprotein cholesterol (LDL-C), triglyceride (TG), and total cholesterol (TC) at 6 months for each category of the modified MDA items were calculated through multivariate logistic regression analysis. The odds for controlled LDL-C was higher among those who consumed cholesterol-rich foods <1 time/week (3.27, 1.25–8.57) than for those who did so ≥4 times/week. The odds for controlled TG was higher among those who always consumed dairy products (2.96, 1.36–6.44), ate protein-rich foods three times/day (2.94, 1.06–8.10), and had a regular eating schedule (3.02, 1.30–7.00) than among those who did not have any of these. The odds for controlled TC was higher among those with a regular eating schedule (3.47, 1.55–7.76) than among their counterparts. Patients with dyslipidemia should consume less cholesterols, consume more dairy and protein-rich foods, and follow a regular eating schedule to control lipid profiles.

Dyslipidemia and Rate of Under-Target Low-Density Lipoprotein-Cholesterol in Patients with Coronary Artery Disease in Korea

Objective

The aim of this study was to evaluate under target rates of low-density lipoprotein-cholesterol (LDL-C) in Korean patients with stable coronary artery disease (CAD) or an acute coronary syndrome (ACS) in real world practice.

Methods

Dyslipidemia International Study II was an international observational study of patients with stable CAD or an ACS. Lipid profiles and use of lipid-lowering therapy (LLT) were documented at enrollment, and for the ACS cohort, 4 months follow-up was recommended. Rates of under target LDL-C as per European guidelines, were evaluated, and multivariate regression was performed to identify predictive factors of patients presenting under the target.

Results

A total of 808 patients were enrolled in Korea, 500 with stable CAD and 308 with ACS. Of these, 90.6% and 52.6% were being treated with LLT, respectively. In the stable CAD group, 40.0% were under target LDL-C, while in ACS group, the rate was 23.7%. A higher statin dose was independently associated with under target LDL-C in both groups (OR, 1.03; p=0.046 [stable CAD] and OR, 1.05; p=0.01 [ACS]). The mean statin dosage (atorvastatin equivalent) was 17 mg/day. In the 79 ACS patients who underwent the follow-up examination, the LDL-C under target rate rose to 59.5%.

Conclusion

Only a minority of patients with stable CAD or ACS were under their target LDL-C level at enrollment. The statin dose was not sufficient in the majority of patients. These results indicate a considerable LLT gap in Korean patients with established CAD.

Observational Prospective study to esTIMAte the rates of outcomes in patients undergoing PCI with drug-eluting stent implantation who take statins -follow-up (OPTIMA II)

OBJECTIVE

The OPTIMA II study sought to evaluate rates of major adverse cardiac and cerebrovascular events (MACCEs) during the long-term follow-up of chronic statin users who underwent percutaneous coronary intervention (PCI) with implantation of a drug-eluting stent (DES).

RESEARCH DESIGN AND METHODS

OPTIMA II was a non-interventional, observational study conducted at a single center in the Russian Federation. Included patients were aged ≥18 years with stable angina who had received long-term (≥1 month) statin therapy prior to elective PCI with DES implantation and who had participated in the original OPTIMA study. Patients received treatment for stable angina after PCI as per routine study site clinical practice. Study data were collected from patient medical records and a routine visit 4 years after PCI.

CLINICAL TRIAL REGISTRATION

NCT02099565.

MAIN OUTCOME MEASURES

Rate of MACCEs 4 years after PCI.

RESULTS

Overall, 543 patients agreed to participate in the study (90.2% of patients in the original OPTIMA study). The mean (± standard deviation [SD]) duration of follow-up from the date of PCI to data collection was 4.42 ± 0.58 (range: 0.28-5.56) years. The frequency of MACCEs (including data in patients who died) was 30.8% (95% confidence interval: 27.0-34.7); half of MACCEs occurred in the first year of follow-up. After PCI, the majority of patients had no clinical signs of angina. Overall, 24.3% of patients discontinued statin intake in the 4 years after PCI. Only 7.7% of patients achieved a low-density lipoprotein (LDL) cholesterol goal of <1.8 mmol/L. Key limitations of this study related to its observational nature; for example, the sample size was small, the clinical results were derived from outpatients and hospitalized medical records, only one follow-up visit was performed at the end of the study (after 4 years' follow-up), only depersonalized medical information was made available for statistical analysis, and adherence to statin treatment was evaluated on the basis of patient questionnaire.

CONCLUSIONS

Long-term follow-up of patients who underwent PCI with DES implantation demonstrated MACCEs in nearly one-third of patients, which is comparable to data from other studies. PCI was associated with relief from angina or minimal angina frequency, but compliance with statin therapy and the achievement of LDL cholesterol targets 4 years after PCI were suboptimal.

Physicians' behavior following changes in LDL cholesterol target goals

Background

In 01/2011 Clalit Health Services (CHS), changed the LDL-Cholesterol target definitions in its quality indicators program, from a universal target to values stratified by risk assessment based on ATP III criteria. The objective of this study is to evaluate the effect of this change on achievement of LDL-C targets and on physicians’ prescriptions of statins.

Study Design: A descriptive study based on administrative dataset 06/2010-06/2012.

Methods

Setting: CHS, The largest health maintenance organization in Israel that insures above 4,000,000 beneficiaries.

Patients: Patients who had been in the same risk group throughout the study period.

Measurements: Attainment of targets for LDL-C and purchases of statins prior to, and following, implementation of the guidelines in the CHS quality indicators program.

Results

433,662 patients remained in the same risk groups throughout the study period; 55.8% were women; the average age was 53.0 ± 10.3 years; 63.9%, 13.4%, and 22.7% were at low, medium, and high risk respectively. After implementation, the proportion of patients reaching LDL-C targets increased in all risk groups: from 58.6% to 61.6%, from 55.1% to 61.1%, and from 44.5% to 49.0%, in low, medium, and high risk groups respectively (p < 0.001). The proportion of patients treated with potent statins increased in all risk groups; from 3.4% to 5.6%, from 6.7% to 10.3%, and from 14.5% to 20.3% respectively (p < 0.001).

Conclusion

The risk stratification approach as a basis for the quality indicators program was implemented and better achievement of target LDL-C levels ensued. We suggest that implementation of quality indicators that are consistent with the current literature can lead to improvements that exceeds temporal trends.
