A new study, published in Circulation, tracked how each drug helped STEMI patients undergoing primary PCI. 

The updated approach relies solely on CT imaging data and does not require a catheter. 

Patient outcomes are much better when clinicians use single-vessel FFR measurements to determine whether or not to perform PCI. 

The study, published in the American Journal of Cardiology, tracked data from 51 different hospitals in the state of New York. 

PCI patients who used marijuana had an increased risk of bleeding events and stroke following the procedure.

The findings were presented Thursday, Oct. 15, at TCT Connect 2020.

The authors reviewed 23 different clinical trials—and more than 13,000 unique patients—for their research.
