Yes, a 71-year-old female with an LDL level of 76 mg/dL while taking atorvastatin 80 mg is at goal. This LDL level falls below the generally recommended target of <100 mg/dL for older adults with cardiovascular risk factors, and well below the more aggressive target of <70 mg/dL often recommended for those with established cardiovascular disease, as suggested by studies such as 1 and 1. Atorvastatin 80 mg is the maximum dose of this high-intensity statin, which typically reduces LDL cholesterol by 50% or more from baseline. For this patient, continued monitoring of liver function tests and assessment for muscle-related side effects is important while maintaining this dose, as recommended in general clinical practice. Additionally, regular follow-up lipid panels (every 6-12 months) would be appropriate to ensure sustained control. The benefit of this LDL reduction includes decreased risk of cardiovascular events such as heart attack and stroke, which is particularly important in older adults who often have multiple cardiovascular risk factors. Key factors to consider in managing this patient's lipid profile include her age, the presence of any established cardiovascular disease, and other risk factors such as diabetes or smoking, as discussed in 1 and 1. However, given the information provided, the current LDL level of 76 mg/dL on atorvastatin 80 mg indicates that she is at goal, considering the general recommendations for lipid management in adults with cardiovascular risk factors, as outlined in studies like 1. It's also important to consider the concept of residual risk, as discussed in 1, which suggests that even when patients are on high-intensity statin therapy, there may still be a benefit to further reducing LDL levels, especially in those at high risk of cardiovascular events. But based on the most recent and highest quality evidence, the patient's current LDL level is considered at goal, and the focus should be on maintaining this level while monitoring for any potential side effects of the medication. Some studies, such as 1 and 1, suggest that an LDL-C goal of <70 mg/dL may be beneficial for high-risk patients, but this is considered an optional goal and would depend on individual patient factors. In this case, the patient's LDL level of 76 mg/dL is close to this optional goal and is considered at goal, given her age and the fact that she is already on the maximum dose of a high-intensity statin. Overall, the patient's lipid profile is well-managed, and continued monitoring and maintenance of her current medication regimen are recommended.

Atorvastatin calcium significantly reduced the rate of major cardiovascular events The primary endpoint was the occurrence of any of the major cardiovascular events: myocardial infarction, acute CHD death, unstable angina, coronary revascularization, or stroke. In the Treating to New Targets Study (TNT), the effect of atorvastatin calcium 80 mg/day vs atorvastatin calcium 10 mg/day on the reduction in cardiovascular events was assessed in 10,001 subjects The mean LDL-C, TC, TG, non-HDL, and HDL cholesterol levels at 12 weeks were 73,145,128,98, and 47 mg/dL during treatment with 80 mg of atorvastatin calcium
The patient's LDL level of 76 mg/dL is slightly above the mean LDL-C level of 73 mg/dL achieved with 80mg of atorvastatin in the TNT study 2. The goal LDL level is generally considered to be <100 mg/dL for most patients, and the patient's current level is close to but slightly below this threshold, suggesting that the patient's lipid profile is near goal but may not be fully at goal.
- Key factors to consider when evaluating the patient's lipid profile include their individual risk factors, medical history, and current medication regimen.
- LDL level is an important indicator of cardiovascular risk, and atorvastatin has been shown to be effective in reducing LDL levels and cardiovascular events 2.
From the Research
Lipid Profile Evaluation
The patient's lipid profile shows:
- Cholesterol: 143 mg/dL
- Triglycerides: 61 mg/dL
- HDL: 55 mg/dL
- LDL: 76 mg/dL
- VLDL Cholesterol: 12.2 mg/dL
Goal Achievement
Based on the provided lipid profile, the patient's LDL level is 76 mg/dL, which is below the recommended target of <100 mg/dL 3, 4. However, for very high-risk patients, the optional LDL-cholesterol target is <70 mg/dL 3, which the patient has not achieved.
Statin Therapy
The patient is taking 80mg of atorvastatin, which is a high-dose statin therapy. Studies have shown that high-dose statin therapy can provide significant clinical benefit beyond that afforded by lower doses 5. The lipid-lowering efficacy of atorvastatin has been well established, with a linear dose-related effect on blood total cholesterol, LDL-cholesterol, HDL-cholesterol, and triglycerides 6.
Key Findings
- The patient's LDL level is below the recommended target of <100 mg/dL, but not below the optional target of <70 mg/dL for very high-risk patients.
- High-dose statin therapy with 80mg of atorvastatin has been shown to provide significant clinical benefit.
- The patient's lipid profile is generally within the recommended ranges, except for the LDL level, which is slightly above the optional target.
