Percutaneous Coronary Intervention Patients

This study is a two-arm randomized parallel group trial designed to compare the effects of Incentive spirometry vs diaphragmatic breathing on oxygen saturation and Heart-rate variability in hemodynamically stable post-PCI patients. Participants will be randomly allocated to either the incentive spirometry group or the diaphragmatic breathing group and will receive the allocated intervention for 2 consecutive days with three supervised sessions per day in addition to routine post-PCI care. Oxygen saturation will be assessed using a pulse oximeter and heart-rate variability will be assessed using a Polar H10 sensor at baseline and after the intervention. The study will determine whether there is a difference between two interventions in the prescribed outcome measures.

This study aims to evaluate the effectiveness of a video-based educational intervention in reducing anxiety among hospitalised patients scheduled for elective percutaneous coronary intervention (PCI). Participants will be assigned to either a video intervention group or a control group without randomisation. The intervention group will receive a structured educational video related to the PCI procedure, while the control group will receive usual care. Anxiety levels will be measured using the State-Trait Anxiety Inventory at baseline and after the intervention to determine whether the video intervention reduces anxiety before the procedure.
