Purpose: Lipid lowering treatments (LLTs) can reduce the risk of atherosclerotic cardiovascular disease (ASCVD). Despite the availability of potent LLTs, our clinical observations suggest an inadequate use of such agents. To evaluate this treatment deficit, we designed the present study. Methods: We reviewed the charts of all patients with a history of ASCVD (coronary artery disease—CAD; carotid stenosis—CS; or peripheral artery disease—PAD) diagnosed prior to their first visit to one of our clinics. We recorded their gender, age, ASCVD risk factors (diabetes, hypertension, tobacco use, body mass index), lipid values during that visit and the LLT used. We estimated the rates of the attainment of guideline-specific lipid goals by year, and assessed factors influencing the likelihood of treatment success. Results: Overall, n = 1003 subjects were recruited: CAD n = 703 (70.1%), PAD n = 168 (16.8%), CS n = 325 (32.4%); age 64.7 ± 11.2 years; n = 376 (37.5%) females; n = 642 (64.0%) had diabetes; n = 740 (73.8%) had hypertension; n = 299 (29.8%) were former and n = 367 (36.6%) were current smokers. An appropriate LLT was used in 361 (36.0%) subjects, n = 159 (15.9%) were on no treatment, n = 483 (48.2%) were receiving inadequate therapy, n = 434 (43.3%) were on a high-intensity LLT and n = 361 (36.0%) had achieved the year-specific LDL goals. Success rates ranged from 5.7% to 81.5%, with the lowest being 2020–2023 (5.7–14.5%), p < 0.001. The use of a combination of LLTs and PCSK9 inhibitors led to higher rates of LDL-C goals achievement (p < 0.001). Discussion: Recent secondary ASCVD risk prevention guidelines’ goals are rarely achieved in daily clinical practice, producing a major treatment deficit in this population. Newer systematic interventions are needed to curb this public health issue.
