A 64-year-old man is evaluated in the outpatient clinic for a severe major depressive episode 3 months after suffering an acute anterior myocardial infarction. He is currently hemodynamically stable and compliant with his post-myocardial infarction medical regimen, which includes dual antiplatelet therapy. He reports pervasive anhedonia, early morning awakening, profound fatigue, and feelings of worthlessness. Over the subsequent 18 months, despite extensive medical management, his depressive disorder proves highly resistant to standard therapies, eventually precipitating a severe clinical deterioration characterized by extreme food refusal, profound dehydration, and catatonic posturing requiring emergent hospitalization.
Arrange the following psychiatric management steps in the most appropriate, evidence-based chronological sequence for this patient, from initial evaluation in the outpatient clinic to the management of his final acute decompensation.
- 1Perform a comprehensive safety assessment and meticulously screen for a history of manic or hypomanic episodes.
- 2Initiate monotherapy with sertraline, ensuring careful monitoring for gastrointestinal bleeding risk.
- 3Augment the regimen with an atypical antipsychotic (e.g., aripiprazole) or cross-taper to an alternative first-line antidepressant class following failure of an 8-week optimized trial.
- 4Admit for inpatient psychiatric stabilization and administer urgent electroconvulsive therapy (ECT).
