Unstable Angina

Results from thrombosis, breaking of weak cap.

Stable Angina

Predictable with exercise, subsides with rest, perhaps nitro.

Unstable Angina

Comes unexpectedly, lasts longer than 15 minutes.

PTCA

Catheter introduces balloon into coronary artery, inflates to reduce thrombus to less than 50% lumen obstruction. pt on IV heparin, nitroglycerin, and abciximab
