Insights
Overall, 58% of patients met low-density lipoprotein cholesterol (LDL-c) targets. However, only 26% of high-risk patients achieved their LDL-c goals, highlighting the need for more aggressive statin therapy in secondary prevention.
Area of Science:
- Cardiology
- Lipid Metabolism
- Preventive Medicine
Context:
- Assessing achievement of current low-density lipoprotein cholesterol (LDL-c) targets is crucial for cardiovascular risk management.
- Guidelines like NCEP-ATP III provide benchmarks for LDL-c levels based on patient risk stratification.
- Cardiovascular clinics manage diverse patient populations with varying risk profiles.
Purpose:
- To determine the proportion of patients achieving target LDL-c levels based on new guidelines.
- To evaluate LDL-c target attainment across different cardiovascular risk groups.
- To identify factors associated with achieving LDL-c goals, particularly in high-risk individuals.
Summary:
- A study of 1,811 patients found 58% achieved target LDL-c levels.
- Achievement rates varied significantly by risk group: 26% (high-risk), 51% (intermediate-risk), and 86% (low-risk).
- Statin treatment was a significant factor in achieving LDL-c targets for high-risk patients.
Impact:
- Findings underscore the need for more aggressive statin therapy in high-risk patients for effective secondary prevention.
- Current treatment strategies may be insufficient for a substantial portion of high-risk individuals.
- Improved lipid management is essential to reduce cardiovascular events.
Background And Objective:
Our goal was to determine the number of patients who achieve low-density lipoprotein cholesterol (LDL-c) targets according to new guidelines.
Patients And Method:
Descriptive and transversal study of patients from a cardiovascular clinic. LDL-c was calculated and targets were established according the NCEP-ATP III.
Results:
1,811 patients (46% males, 54% females) were studied. 35% of these were high-risk patients (group 1: coronary risk > 20% at 10 years), 19% were intermediate-risk patients (group 2: coronary risk 10-20% at 10 years) and 46% were low-risk patients (group 3: coronary risk < 10% at 10 years). Overall, 58% of patients achieved target LDL-c levels, yet success rates were 26% among group 1 patients, 51% among group 2 patients, and 86% among group 3 patients (p = 0.001, for differences between groups). Statin treatment was significantly related to achieving target LDL-c levels in group 1 patients (OR = 1.7; 95% CI, 1.2-2.4; p = 0.007). In group 1.41% of patients had LDL-c levels > 130 mg/dl without receiving lipid-lowering drugs.
Conclusions:
Although an overall 58% patients achieve target LDL-C levels, only one of four high-risk patients have LDL-c levels < 100 mg/dl, and statin treatment is a determining factor to achieve this goal. These findings indicate that a more aggressive treatment with statins is needed in secondary prevention.
