Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 44–75 who recently underwent PCI, are stable without ongoing chest pain, can follow simple instructions, have SpO2 ≥ 92% on room air, and have an ejection fraction > 35%.

Probably not a fit

Patients with unstable hemodynamics, ongoing ischemia, significant arrhythmias, implanted cardiac devices with pacing, severe cognitive impairment, or other disqualifying conditions may not benefit.

What this trial studies

This parallel-arm randomized trial compares two breathing exercises—Pilates breathing and diaphragmatic breathing—in adults 44 to 75 years old who are hemodynamically stable after PCI. Participants will receive supervised breathing sessions over two consecutive days, with three sessions per day, in addition to routine care; outcomes include oxygen saturation and heart-rate variability measured during recovery. The study aims to determine which breathing technique better supports early recovery by stabilizing respiration and autonomic regulation. It is conducted at Foundation University Islamabad in Rawalpindi, with 36 participants recruited and randomized using sealed envelopes. The intervention is non-pharmacological and bedside-friendly, designed to be easily integrated into early cardiac rehabilitation if beneficial.

Why it matters

Potential benefit: If successful, breathing exercises could become a simple, non-drug way to support recovery after PCI by improving oxygenation and autonomic balance.

How similar studies have gone: Prior breathing-exercise approaches have shown potential benefits in respiratory function and autonomic regulation in cardiac patients, but direct comparisons like Pilates versus diaphragmatic breathing post-PCI are novel.
