Why the study?
Myocardial ischemia in CAD leads to imbalanced autonomic control that increases morbidity and mortality, prompting investigation into how autonomic function responds to PCI.
Does percutaneous coronary intervention improve heart rate variability in patients with coronary artery disease?
Population
27 CAD patients admitted for PCI
Comparison
ECG measures before vs after PCI
Design
Pilot study
Follow-up
Within 24 h

May signal short-term autonomic benefit post-PCI; hypothesis-generating in this small pilot, needing larger validation.
Does percutaneous coronary intervention improve heart rate variability in patients with coronary artery disease?
Short-term ECG Poincaré plot metrics (AI and PI) may be useful for sensing the beneficial effects of PCI on cardiovascular autonomic control.
