In this brief interview, a patient (Speaker A) describes his physically demanding job—climbing a 20‑foot ladder about 200 times a day—yet reports never feeling winded. During a routine checkup, doctors discovered a severe cardiac issue that required open‑heart bypass surgery using cadaver (donor) veins. The entire diagnostic and treatment process unfolded within roughly 90 days, moving the patient from a seemingly healthy state to preparing for major surgery. The conversation highlights the surprising rapid progression, the lack of prior symptoms, and the nature of the surgical solution.

A typical day when I'm out on the job, I'll be up and down a 20-foot ladder 200 times.
Got it.
And so, so you never get winded.
So you've got these mild— yeah, so you're not showing a lot of symptoms, right? What brought you to this cardiologist in the first place? Like, why did you walk in the first cardiologist's door?
Checkup.
Just a checkup?
A checkup. Wow. And so you went from checkup to open heart bypass surgery with cadaver veins. That's exactly right.
Wow. How long did it take to go down that road? Rabbit hole? About 90 days. In 90 days you went from climbing up ladders, no symptoms, a normal checkup, to we're gonna use cadaver veins, surgery, open-heart surgery, and we're gonna put dead things in you. That's right. Wow. Okay, exactly.
And we hope they're not clogged.
Yeah, that's a pretty bad slope.
