Quick Hit | What Actually Happens When You Walk into the ER with Chest Pain

Welcome to the very first Quick Hit — a brand new bonus series from Overheard in the Emergency Room where Dr Cois tackles the questions you’ve been sending in. Short. Focused. Practical. Today: “What actually happens when I walk into the Emergency Department with chest pain?” Dr Cois walks you through the full chest pain workup — why we move so fast, what door-to balloon time means, the three body systems behind every differential (heart, lungs, GI), which tests get ordered and when, and the diagnoses your ED doctor is quietly thinking about even when they don’t mention them. Plus the most important takeaway: when to come in, and what to do after. This is a clinical overview, not a deep evidence dive — but if you’ve ever sat in an ED waiting room wondering what was actually happening, this is the inside view.
