Summary

This study tests whether using mild electrical pulses on the diaphragm and belly muscles can improve breathing, heart function, and exercise ability in people who recently had a heart artery-opening procedure (angioplasty). 42 adults will receive either standard rehab plus this stimulation, or rehab alone, for 2 weeks. The goal is to see if this extra therapy helps them recover faster.
