Descrizione dettagliata
Percutaneous coronary intervention (PCI) improves coronary blood flow in patients with coronary artery disease; however, many patients continue to experience reduced pulmonary function, impaired gas exchange, decreased cardiac performance, and limited functional capacity after the procedure. These issues are often related to respiratory muscle weakness, immobilization, and altered ventilatory mechanics. Conventional cardiac rehabilitation focuses mainly on aerobic and resistance training, with limited emphasis on respiratory muscle strengthening.
Neuromuscular electrical stimulation (NMES) is a non-invasive technique that induces muscle contractions and may enhance both inspiratory and expiratory muscle function when applied to the diaphragm and abdominal muscles. This study aims to evaluate the effectiveness of combined diaphragmatic and abdominal NMES as an adjunct to standard cardiac rehabilitation in post-PCI patients.
In this randomized controlled trial, 42 hemodynamically stable patients aged 40-75 years will be randomly assigned to either an intervention group (NMES plus standard rehabilitation) or a control group (standard rehabilitation alone). The NMES intervention will be applied for 30 minutes per session, five days per week, for two weeks.
Outcome measures will include arterial blood gases (PaO₂, PaCO₂, SaO₂), pulmonary function (FVC, FEV₁, PEFR), left ventricular ejection fraction, and functional capacity assessed by the 6-minute walk test. Assessments will be conducted at baseline and after the intervention.
This study aims to determine whether NMES can improve respiratory and functional outcomes and serve as an effective adjunct to conventional cardiac rehabilitation in post-PCI patients.

Sperimentale: NMES + Standard Cardiac Rehabilitation
Participants in this group will receive combined diaphragmatic and abdominal neuromuscular electrical stimulation (NMES) in addition to standard cardiac rehabilitation.
NMES will be applied using surface electrodes placed over the lower thoracic region (for diaphragmatic stimulation) and abdominal muscles (rectus abdominis and external obliques).
The intervention will be delivered for 30 minutes per session, five days per week, for two weeks, along with routine cardiac rehabilitation including aerobic exercise, breathing exercises, and education.
|
A dual-channel electrical stimulation device will be used to deliver stimulation to respiratory muscles.
Surface electrodes will be placed over the lower thoracic region for diaphragmatic stimulation and over the abdominal muscles for expiratory muscle stimulation.
Stimulation parameters will include a frequency of 30-50 Hz, pulse width of 300 µs, and a duty cycle of 5 seconds on and 5 seconds off.
Intensity will be adjusted to achieve visible muscle contraction without discomfort.
Sessions will last 30 minutes, five days per week, for two weeks.
