Abstract Context: Low-density lipoprotein cholesterol (LDL-c) plays a key role in the development and progression of atherosclerotic cardiovascular disease (ASCVD). Despite the availability of effective lipid-lowering treatments, patients who have experienced an acute coronary syndrome (ACS) continue to face a high risk of recurrent cardiovascular events and mortality. Achieving the recommended LDL-c target of <0.55 g/L in secondary cardiovascular prevention remains a significant challenge, with fewer than 30% of patients reaching this goal. Aim To investigate the factors influencing LDL-c control after ACS and the effectiveness of intensive teleconsultation monitoring to control LDL-c, even in sub-groups where control is poorest. Methods This bi-centric prospective cohort study conducted between december 2019 and december 2021 compared a group that received standard follow-up after an ACS with an interventional group that received regular follow-up by teleconsultation in addition of usual care to optimize lipid-lowering treatment. A subgroup analysis was carried out to examine the effect of teleconsultation in subpopulations known to be significantly associated with better or worse LDL-c control in the usual care group or described in the literature. Results 1602 patients met the inclusion criteria for our study (814 in the usual care group and 788 in the teleconsultation group). Baseline characteristics were similar between groups. In the usual care group, factors influencing lipid control included gender, diabetes, cardiology consultation, distance to the nearest cardiologist, social deprivation and initial LDL-C levels. Teleconsultation significantly improved LDL-C target attainment compared to usual care (74.7% vs. 26.6%, p<0.001 with multivariate analysis OR 5.06 [4.21 ; 6.07]), particularly benefiting geographically and socially disadvantaged patients. Conclusion Teleconsultation significantly improves lipid control in acute coronary syndrome patients compared to usual care. This universal intervention, particularly beneficial for geographically and socially disadvantaged patients, highlights the potential of telemedicine in enhancing cardiovascular management.analysis in usual care groupTeleconsultation effect in sub-groups
