I'm really concerned about my father's angiography report and was hoping you could take a look. It mentions a 60% lesion in the mid LAD, an 80% lesion in the proximal segment of the LCX, and a 90% lesion in the mid RCA. Does he need an angioplasty, and how many of these blockages should it address?

Whether angioplasty is required depends on a lot of factors. Of course the percentage of narrowing is an important factor. In case your cardiologist has suggested angioplasty it will most likely be necessary. But in case you want to be doubly sure, it will be worth considering a second opinion from another cardiologist.
