Experiences of People Diagnosed with High Levels of LDL Cholesterol and Atherosclerotic Cardiovascular Disease: Results from a Multinational Qualitative Study.

Background: Elevated low-density lipoprotein cholesterol (LDL-C) levels are a leading risk factor for atherosclerotic cardiovascular disease (ASCVD), a major global cause of illness and death. Patients' qualitative insights about experiences, priorities, and needs are essential for creating more targeted, patient-centered quality improvement interventions. Objectives: To document the experiences of people with high levels of low-density LDL-C in three countries. Methods: Qualitative study of 60-min in-depth interviews with 50 adult patients from Australia, Brazil, and the United States. The study was overseen by a Steering Committee comprising patients, patient advocates, researchers, and cardiologists. The interviews explored pathways and barriers to high LDL-C diagnosis; the burden of managing high LDL-C and the awareness of the association between high LDL-C and cardiovascular risks. The data were analyzed by applying a structured, team-based approach to coding qualitative data. Results: There were three main pathways to diagnosing high cholesterol: routine physical exams conducted by primary care providers; symptomatic presentations or incidental findings during emergency visits and through a healthcare visit for another condition, frequently diabetes. Healthcare providers' communication styles influenced patients' perceptions of their conditions. Two-thirds of participants ( Conclusions: This pilot study provides insights into patients' experiences living with and managing elevated LDL-C. It describes opportunities for policymakers and healthcare providers to improve the detection of elevated LDL-C and support patients in understanding risks and strategies for reducing the risk of ASCVD events.
