I'm a third-year medical resident rotating in the emergency department, and I'm finding the sheer volume of potential causes for a chief complaint of chest pain overwhelming when trying to form a rapid yet thorough differential diagnosis under pressure. While we're heavily protocol-driven for ruling out life-threatening causes like ACS or PE, I struggle with confidently identifying and managing the more nuanced presentations, such as differentiating between musculoskeletal pain, GERD, pericarditis, or early atypical cardiac events in younger patients. For more experienced clinicians, what mental frameworks or clinical pearls do you rely on to efficiently narrow your differential for chest pain? How do you balance the imperative to rule out the worst-case scenarios with avoiding excessive testing, especially in patients with ambiguous presentations or complex medical histories?
