Effect of the Final Coronary Arterial Diameter After Coronary Angioplasty on Heart Rate Variability Responses

Abstract

Transient and rapidly recovered, especially parasympathetically modulated HRV reduction occurred after PTCA in patients with single-vessel disease. HRV reduction is associated with PTCA restenosis risk score and the degree of revascularization as invasive feature of angioplasty, hence it may be related to reperfusion.
