Association of Beta Blocker Use with Depressive Outcomes

Study design- This is a Prospective, Retrospective, Cross-sectional observational study. In prospective study, cardiovascular patients will be divided into two groups: those taking β-blockers and those not taking β-blockers. A questionnaire-based study will be conducted to assess the depression status of both groups. The study will include Depression Inventory (MDI) (lCD-10), Hamilton Rating Scale for Depression (HDRS) and Patient health questionnaire-9 (PHQ-9) for prospective study. In the Retrospective study, clinically diagnosed depression patients with cardiovascular co morbidity will be identified from the psychiatric department. Study population- Total number of patients to be included in both prospective and retrospective study: 1136 Prospective: 684 participants from cardiology department (two subgroups = 342 with β-blockers and other 342 without β-blockers) Retrospective: 452 participants from psychiatric department (two subgroups = 226 with β-blockers and other 226 without β-blockers) Planned time period for the study: Jan 2025 to May 2025 Procedure- Prospective: A prospective study, a total of 684 cardiovascular participants will be recruited from the Cardiology department. Participants will be divided into two groups: participants who are currently on β-blockers from at least 1 year and those who are not on β-blockers. Then a Depression Inventory (MDI) (lCD-10), Hamilton Rating Scale for Depression (HDRS) and PHQ-9 (Patient health questionnaire-9) depression questionnaire will be run on both to assess depression levels. Data collected from both groups will be compared to evaluate differences in depression status. Retrospective: A retrospective study will be conducted involving 452 patients diagnosed with depression and atleast one cardiovascular co morbidity from the psychiatry department. Patients will be classified into two groups: those who were prescribed with β-blockers and those who were not. Medical records of these patients will be obtained from their respective Staff. The primary objective is to determine the prevalence of β-blocker use among depressed patients with cardiovascular conditions by reviewing their medical histories.
