Atorvastatin Plus Escitalopram for Depression With Dyslipidemia

This single-center clinical observational study aims to evaluate the clinical efficacy and safety of combined escitalopram and atorvastatin treatment in adult patients diagnosed with depressive episodes accompanied by dyslipidemia. All enrolled patients will receive routine standardized clinical medication according to their doctor's professional judgment without additional experimental intervention, extra examinations, or modified medical schedules. Researchers will retrospectively and prospectively collect routine clinical data during regular follow-up, including depressive symptom scale scores and blood lipid biochemical indicators, to observe symptom improvement and blood lipid changes before and after combined medication. All adverse reactions occurring during treatment will be systematically recorded to summarize the safety profile of the dual-drug combination. This study does not involve investigational drugs, unapproved medical devices, or U.S. FDA IND/IDE-related procedures. The study strictly follows the principle of voluntary participation and confidential personal information protection, and no additional risks or economic burdens will be brought to the participants.
