QT Interval Dispersion as a New Marker of Restenosis after Percutaneous Transluminal Coronary Angioplasty of Isolated Single-Vessel Coronary Artery Stenosis
Abstract:Background: There are no reliable non-invasive markers of restenosis after percutaneous transluminal coronary angioplasty (PTCA). The aim of our study was to measure changes in QT interval dispersion after PTCA and to determine whether restenosis subsequently affects QT interval dispersion. Methods and Results: Fifty-six consecutive patients – 41 men and 15 women (mean age: 56.2 ±8.3 years) – with isolated stenosis of the left anterior descending artery who underwent successful PTCA were studied. A symptom-lim… Show more
