Introduction Still too few patients after an acute cardiocerebrovascular event reach C-LDL values recommended by guidelines even in therapy with statins and ezetimibe, thus maintaining a high risk of new cardiovascular episodes. Purpose To evaluate, in a long follow-up, the effectiveness and the rapidity of alirocumab in the attainment and maintenance of LDL-cholesterol target values in patients at very high risk and intolerant to statins. Methods Our case studies consist of 72 patients, 80% males (58) and 20% females (14), with an average age of 61.9. 90.2% of patients were hypertensive. 5.5% had chronic kidney disease (CKD stage III). 65.2% had an ACS and the 34.7% had CeVD. 84.7% of the patients were in therapy only with ezetimibe while 15.3% in association with PUFA N-3. The average value of C-LDL was 169.2 mg/dl. The follow up was 24 months with clinical checks and C-LDL at 3,6,12 and 24 months. The dosage of alirocumab was both 75 and 150 mg Results At 3 months the reduction of C-LDL was 52.24%; at 6 months of 51.18%; at 12 months of 51.36% and at 24 months of 52.47%. The 37 patients who had started with 150 mg, had a very high average C-LDL base, 183.0 mg/dl, and showed a reduction of C-LDL to 3 months of 59.04%, to 6 months of 58.45%, to 12 months of 65.05%, to 24 months of 55.76%. The target value of C-LDL recommended by the ESC guidelines was reached for 42.10% at 3 months; for 52.63% at 6 months; for 63.15% at 12 months and for 73.68% at 24 months. 5.5% of patients with a CKD showed a 73.68% reduction in C-LDL values to 3 months, 65.22% to 6 months, 57.49% to 12 months and 53.95% to 24 months. The follow-up to the Tg study showed a reduction of 3.55% to 3 months, an increase of 8.75% to 6 months, a reduction of 1.65% to 12 months and 7.95% to 24 months. C-HDL values showed an increase of 4.55% at 3 months, 3.69% at 6 months, 10.97% at 12 months and 7.82% at 24 months. Conclusions Our case studies have confirmed the effectiveness of alirocumab in reducing C-LDL values in patients at very high cardiovascular risk and the rapidity in reaching the target value set by guidelines for the management of cardiovascular risk. Our study also confirmed the its effectiveness in increasing the values of C-HDL while it was not possible to confirm the reduction of Tg values. % Alirocumab Efficacy C-LDL TGs C-HDL 3 MONTHS -52,24% -3,55% +4,55% 6 MONTHS -51,18% +8,75% +3,69% 12 MONTHS -51,36% -1,65% +10,97% 24 MONTHS -52,47% -7,95% +7,82% C-LDL: LDL-CHOLESTEROL TGs TRIGLYCERIDES C-HDL: HDL-CHOLESTEROL Abstract Figure. % Alirocumab Efficacy
