Lipid-lowering therapy in patients with coronary heart disease: an Italian real-life survey. Results from the Survey on Risk FactOrs and CardiovascuLar secondary prEvention and drug strategieS (SOFOCLES) in Italy

Abstract

In patients at high cardiovascular risk, a low-density lipoprotein cholesterol (LDL-C) reduction of ≥50% from baseline and an LDL-C goal of <70 mg/dL (or <55 mg/dL in very high-risk patients) are recommended. Multiple registry and retrospective studies have shown that patients with high atherosclerotic cardiovascular risk often do not reach the targets defined by the European Society of Cardiology guidelines as a result of suboptimal management of LDL-C. Here, we report the data on lipid-lowering therapy and lipid targets from the Survey on Risk FactOrs and CardiovascuLar secondary prEvention and drug strategieS (SOFOCLES), an observational, prospective study designed to collect data on patients with ischemic heart disease treated at cardiac outpatient clinics across the Italian national territory. We included patients with known coronary heart disease (CHD) who underwent follow-up visits at various outpatient cardiology clinics. A total of 2532 patients were included (mean age: 67±17 years, 80% male). Among patients with available laboratory data (n=1712), 995 (58%) had LDL-C<70 mg/dL, 717 (42%) had LDL-C≥70 mg/dL, and 470 (27%) had LDL-C<55 mg/dL. Patients who more frequently achieved the recommended LDL-C levels were male, had diabetes, had a higher educational level, and performed intense physical activity. Statins were used in 2339 (92%) patients, high-intensity statins (e.g., rosuvastatin 20/40 mg or atorvastatin 40/80 mg) in 1547 patients (61% of the whole population and 66% of patients on statins), and ezetimibe in 891 patients (35%). Patients receiving high-intensity statins tended to be younger, not to have diabetes, and to have been included in a cardiac rehabilitation program. In a real-world sample of Italian patients with CHD, adherence to lipid-lowering therapy fell markedly short of optimal levels. Many patients did not achieve the LDL-C target of 70 mg/dL, and even fewer reached the LDL-C target of 55 mg/dL. Notably, patients with a lower educational level had a greater likelihood of being undertreated. Strategies aimed at improving preventive interventions for CHD and overcoming social disparities should be evaluated and optimized.
