Plasma Lp(a) concentrations are predominantly determined by genetic factors, particularly polymorphisms of the <i>LPA</i> gene, which modulate apolipoprotein(a) [apo(a)] size and influence its hepatic synthesis. Structurally, Lp(a) consists of an LDL-like particle containing apolipoprotein B100, covalently bound to apo(a), conferring markedly enhanced atherogenic, pro-inflammatory, and prothrombotic properties compared with an LDL particle. In the absence of therapies specifically approved for Lp(a) reduction, current clinical management relies on an intensive approach to global cardiovascular risk reduction. ESC/EAS guidelines recommend aggressive lowering of LDL cholesterol, particularly through high-intensity statin therapy and, in patients at high or very high risk, the addition of ezetimibe and PCSK9 inhibitors, in order to mitigate the residual risk associated with elevated Lp(a) levels. Lipoprotein apheresis represents the only intervention capable of producing a substantial and immediate reduction in Lp(a); however, its use is limited to selected patients due to its invasive nature and limited availability. In parallel, innovative therapies targeting <i>LPA</i> gene silencing-such as antisense oligonucleotides and small interfering RNA-as well as oral agents inhibiting Lp(a) assembly, are in advanced stages of development.

Despite these developments, coronary artery bypass grafting often remains the guideline-preferred strategy for patients with complex and prognostically significant coronary artery disease. However, patients with complex and advanced coronary artery disease are often older and burdened by greater comorbidity than those enrolled in randomized clinical trials, rendering many patients poor surgical candidates, and prompting preference for less invasive therapies to preserve quality of life. This shift has driven the emergence of complex, high-risk indicated PCI (CHIP) and protected PCI as alternative treatment strategies. CHIP encompasses both anatomical complexity and heightened procedural risk related to haemodynamic compromise and patient comorbidities. As randomized trials capture only a small subset of real-world patients and are often subject to selection bias, current practice relies heavily on observational data-derived largely from registries, expert consensus, and institutional experience-to guide selection of patients most likely to benefit from MCS support. This review synthesizes available contemporary evidence and consensus frameworks to delineate the multifactorial nature of CHIP risk, organizing key determinants into four categories: complex coronary anatomy, impaired haemodynamics, cardiac comorbidities, and non-cardiac comorbidities.
