Cardiovascular diseases (CVD) are the leading cause of global mortality, resulting in millions of deaths each year, necessitating innovative management strategies. Dietary interventions have shown prominent outcomes. Lingonberry (Vaccinium vitis-idaea L.) has cardioprotective attributes due to their high polyphenolic and anthocyanin content. The polyphenols, especially anthocyanins, can alleviate oxidative stress and support endothelial function, thus contributing to inflammation reduction and arterial plaque stabilization, which are pivotal for enhanced vascular health. Lingonberry exerts lipid-modulating effects, which are crucial for managing hyperlipidemia, a major CVD risk factor, by effectively reducing low-density lipoprotein (LDL) cholesterol and triglyceride levels. Additionally, lingonberry exhibits beneficial effects in metabolic dysfunction-associated steatotic liver disease (MASLD) and its cardiovascular risk implications, primarily by improving hepatic lipid metabolism. Moreover, they offer renal protection in the context of chronic kidney disease (CKD), thereby extending the beneficial effect in CVD. The cardiovascular benefits of lingonberry, emphasizing their multifaceted roles as antioxidants, anti-inflammatory agents, and lipid-lowering entities, are described. Such insights underline the potential of lingonberries as a valuable component in dietary interventions aimed at combating cardiovascular diseases. Through a comprehensive analysis of current research, this review seeks to enhance the understanding of lingonberry’s therapeutic potential in holistic CVD management strategies.
