Statin Therapy and Cardiovascular Prevention: Contemporary Evidence, Challenges, and Future Directions-A Narrative Review.

Cardiovascular disease (CVD) remains the leading cause of morbidity and mortality worldwide, and lowering low-density lipoprotein cholesterol (LDL-C) remains a cornerstone of cardiovascular prevention. Statins are among the most extensively studied and widely prescribed medications and have demonstrated substantial benefits in reducing major adverse cardiovascular events in both primary and secondary prevention settings. Nevertheless, the effectiveness of statin therapy in routine clinical practice is frequently compromised by poor adherence, treatment discontinuation, concerns regarding adverse effects, and persistent residual cardiovascular risk. This narrative review synthesises contemporary evidence relating to the mechanisms of action of statins, their role in primary and secondary prevention, determinants of medication adherence, statin-associated muscle symptoms (SAMSs), and emerging developments in precision cardiovascular medicine. Current evidence indicates that although statins remain highly effective in reducing cardiovascular risk, long-term treatment success is strongly influenced by behavioural, psychological, social, and healthcare system factors. Increasing attention has also been directed towards the multifactorial nature of SAMSs and the contribution of nocebo effects to perceived statin intolerance. Emerging approaches involving pharmacogenomics, artificial intelligence, digital health technologies, and multidimensional risk assessment offer opportunities for more individualised prevention strategies, although important limitations relating to cost, accessibility, and external validity remain. Overall, contemporary cardiovascular prevention requires a patient-centred approach that integrates biological, behavioural, and social determinants of health to optimise treatment adherence and improve long-term cardiovascular outcomes.
