Patient Autonomy and Statin Therapy Adherence

The rationale for the Patient Autonomy and Statin Therapy Adherence (PASTA) trial is based on the fact that statin therapy is a highly effective and evidence-based treatment for reducing the risk of cardiovascular disease. However, despite the proven benefits of statin therapy, a significant proportion of patients decline to take statins due to concerns about side effects, safety, or a preference for alternative treatments.

One potential strategy to improve statin adherence in patients who decline therapy is to give patients more autonomy in selecting their treatment options. By offering patients a choice between a traditional statin medication (atorvastatin) or a "natural" statin alternative (red yeast rice extract) and involving them in the goal-setting process for their LDL-C levels, patients may feel more empowered and engaged in their own care.

The PASTA trial aims to evaluate whether greater patient autonomy leads to improved adherence to statin therapy in patients who decline initial therapy. By measuring the impact of patient autonomy on statin adherence, the study results may provide valuable insights into how to improve patient engagement and health outcomes in a population that may be hesitant to initiate statin therapy.

Statin therapy is an integral tool in the primary and secondary prevention of atherosclerotic cardiovascular disease (ASCVD). Higher compliance with their statin therapy is associated with a lower risk of mortality in a step-wise manner . Despite this, rates of statin compliance are abysmally low. Prior studies suggest that less than 40% of primary prevention patients are compliant with their prescribed statin therapy. Individuals who have suffered a prior MI have an incremental improvement in compliance to around 60%. Younger individuals and women appear to have exceptionally low rates of compliance to statin therapy . Low rates of compliance remains a significant barrier to reducing the burden of ASCVD, with some suggesting efforts to increase compliance can have an oversized impact on reducing rates of ASCVD .

On the other hand, patients often prefer "natural" therapies over conventional medicine for a variety of reasons. Monacolin-K is a naturally occurring molecule in red yeast-rice extract, a commonly used health supplement. It is structurally identical to lovastatin and has been shown to reduce LDL-C levels and ASCVD events in randomized placebo controlled trials.

Patient autonomy is a core bioethical principle affirming the right of the patient to determine the trajectory of their health care at times. This bioethical principle has been referred to as "first among equals", implying that it is the most important bioethical principle. The role of autonomy in patient compliance is not entirely clear, but there is evidence that suggests that increased patient autonomy in the decision-making process can result in higher rates of long term compliance.
