BackgroundPeripartum cardiomyopathy (PPCM) is a rare, potentially life threatening condition with nonspecific heart failure symptoms, often leading to delayed diagnosis. Large language models (LLMs) may support differential diagnosis suggestion.ObjectivesTo assess whether commonly available LLMs can suggest PPCM and differential diagnoses based on typical symptoms.DesignComparative evaluation of three LLMs using standardized clinical scenarios.MethodsChatGPT (GPT-5), Gemini (2.5 Flash), and Claude (Sonnet 4.5) were queried with prompts describing a 34-year-old woman with PPCM-related symptoms, with and without postpartum context. Responses were analyzed for PPCM and key differential diagnoses recommended by the European Society of Cardiology.ResultsChatGPT and Claude consistently identified PPCM. Gemini suggested PPCM mainly when dyspnea or edema were present and required postpartum context when palpitations were reported. Claude listed the most differential diagnoses.ConclusionLLMs are a valuable tool among differential diagnosis suggestion but performance varies and cannot replace clinical judgment.
