Why the study?
Percutaneous coronary intervention may restore autonomic balance in stable coronary artery disease, but whether preprocedural anxiety impacts the post-PCI increase in heart rate variability was unknown.
Does preprocedural anxiety impact the increase in heart rate variability following elective PCI in patients with stable coronary artery disease?
Does preprocedural anxiety impact the increase in heart rate variability following elective PCI in patients with stable coronary artery disease?
Preprocedural anxiety may blunt the expected improvement in autonomic balance (measured by HRV) following elective PCI in patients with stable coronary artery disease.
Does not support changing pre-PCI anxiety management; hypothesis-generating for autonomic recovery in stable CAD.
BACKGROUND: There is a strong association between chronic ischemia and autonomic imbalance. Percutaneous coronary intervention (PCI) may restore autonomic balance in patients with stable coronary artery disease (SCAD), which is characterized by increased heart rate variability (HRV). Anxiety is often found in patients who are going to undergo invasive procedures and has been identified to induce autonomic imbalance. The aim of our study is to identify the impact of preprocedural anxiety on increased HRV following an elective PCI. METHODS: Our study was a pretest and post-test correlation study involving 44 SCAD patients who underwent elective PCI at Cipto Mangunkusumo National Hospital. The HRV was measured before and after PCI. Anxiety symptoms were evaluated using Hospital Anxiety Depression Score (HADS) questionnaires. CONCLUSIONS: Preprocedural anxiety may inhibit HRV increase following PCI procedure.
