title: Ask the doctor. I was recently admitted to the hospital in the middle of the night with chest pain. When the doctors took my blood pressure, they found that it was much lower in my right arm than in my left. They rushed me in for a CT scan, saying they were looking for a "tear." Fortunately, there wasn't one, and the next day I underwent angioplasty. What was this tear they were worried about?
