Chest Pain that is 1% deadlier every hour

She was rushed into the cath lab for a heart attack. Five failed attempts later, the cardiologist realized this wasn't a heart attack at all — and every drug she'd already been given was about to make it so much worse. Aortic dissection is a "chameleon diagnosis": it hides behind the same chest pain, the same ECG changes, and the same elevated troponins as a heart attack — but the treatment for one can kill you if you actually have the other. A third of dissections get misdiagnosed as heart attacks, and this video breaks down exactly why: the two cognitive biases that make doctors' brains skip right past it, the risk factors that should raise a red flag, and the one question you can ask in an ER that fights back against both biases at once. This is part of an ongoing series on how and why misdiagnosis happens — not to make you afraid of doctors, but to make you a better second set of eyes in the room when it matters most. ⏱️ TIMESTAMPS 0:00 – The cath lab realization: this isn't a heart attack 1:05 – What aortic dissection actually is (and why it's deadlier) 2:20 – Aortic dissection vs heart attack similarities 2:58 – How doctors' brains miss it 3:33 – Bias #1: Availability bias 4:06 – Bias #2: Premature closure 4:53 – The bigger picture: 800,000 Americans harmed by misdiagnosis every year 5:33 – how you can prevent this for yourself My channel focuses on diagnostic clarity — how diagnosis actually works, where it breaks down, and how you can advocate for yourself inside a system that doesn't always get it right the first time.
