Cardiovascular Ultrasound for the Rehabilitation of Patients With Coronary Heart Disease After PCI

Participants in the intervention group will be treated with a medical LIPUS device (838C-M-L-I/II, Shenzhen, China) for 10 days in addition to conventional medical treatment. The ultrasound therapy instrument is equipped with a sound head comprising 5 transducer units, operating at an ultrasonic frequency of 0.84MHz with a sound intensity range of 1 W/cm2 -1.25 W/cm2. The therapeutic ultrasound sessions necessitate a controlled environmental temperature. Patients will assume the supine position, exposing the precordial region, with the five-pronged head positioned parallel to the heart\'s long axis, covering the entire precordial region including the right and left coronary arterial trunks and the aortic root. The ultrasound therapy device operates in a pulsed mode, with each treatment session lasting 20 minutes, comprising 2 daily sessions for a total of 20 treatments.
