From the Guidelines
For patients with coronary artery disease (CAD), the goal LDL cholesterol level should be lowered to <1.4 mmol/L (<55 mg/dL) and reduced by at least 50% if the baseline LDL-C level is 1.8-3.5 mmol/L (70-135 mg/dL). This recommendation is based on the most recent guidelines, specifically the 2020 ESC guidelines for the management of acute coronary syndromes in patients presenting without persistent ST-segment elevation 1. The guidelines emphasize the importance of managing dyslipidaemia with pharmacological and lifestyle interventions, considering statin treatment irrespective of LDL-C levels.
- Key points to consider:
- Statin treatment is essential for patients with established CAD, regardless of their LDL-C levels
- The goal of treatment is to lower LDL-C to <1.4 mmol/L (<55 mg/dL) and to reduce it by at least 50% if the baseline LDL-C level is 1.8-3.5 mmol/L (70-135 mg/dL)
- When the target level cannot be achieved, the addition of ezetimibe has been demonstrated to decrease cholesterol and cardiovascular events in post-ACS patients and in patients with diabetes 1
- Treatment options:
- High-intensity statin therapy as the first-line treatment
- Addition of ezetimibe if the target LDL level cannot be achieved
- Consideration of PCSK9 inhibitors for patients with very high-risk features or those who cannot reach goals with these medications
- Lifestyle modifications:
- Heart-healthy diet
- Regular exercise
- Weight management
- Smoking cessation These recommendations are based on the latest evidence and prioritize reducing morbidity, mortality, and improving quality of life for patients with CAD 1.
From the Research
Goal LDL for CAD
The goal LDL for coronary artery disease (CAD) patients varies based on their risk factors and guidelines.
- For moderate-risk individuals, the recommended LDL goal is less than 130 mg/dL 2.
- However, for those at moderately high risk of developing CAD, an LDL goal of less than 100 mg/dL is recommended 2.
- For patients with stable CAD, an LDL goal of less than 70 mg/dL is suggested 3, 4.
- An even lower LDL goal of less than 55 mg/dL is recommended for patients at extreme cardiovascular risk, such as those with diabetes mellitus or heterozygous familial hypercholesterolaemia (HeFH) 5, 4.
Factors Influencing LDL Goal Attainment
Several factors can influence the attainment of LDL goals in CAD patients, including:
- Use of statin therapy, with moderate- to high-potency doses and combination therapy with other lipid-lowering drugs being more effective 3, 6.
- Frequency of LDL measurements, with more frequent measurements associated with better attainment of LDL goals 3.
- Patient characteristics, such as age, sex, and history of creatine kinase elevation, which can affect the likelihood of attaining LDL goals 6.
Treatment Strategies
To achieve the recommended LDL goals, treatment strategies may include:
- Use of statins as first-line therapy, with up-titration to the highest recommended and tolerable dose 4.
- Combination therapy with statins and other lipid-lowering drugs, such as ezetimibe or PCSK9 inhibitors 5, 4.
- Regular monitoring of LDL levels to adjust treatment and ensure attainment of LDL goals 3.
