Correlation of QT interval prolongation with the severity of heart failure: A longitudinal study
Abstract
Heart failure (HFrEF or HFpEF) patients are at risk for arrhythmic events and mortality, yet the role of QT interval prolongation as a prognostic marker in this population remains poorly understood. Patients with heart failure (HFrEF or HFpEF) were assessed for changes in QT interval, NYHA class, LVEF, BNP levels and hospitalizations. Results showed significant associations between prolonged QT interval and worsening heart failure, with increased risks of arrhythmic events and mortality. The advancement to knowledge in this study is the identification of QT interval prolongation as a significant prognostic marker for heart failure severity.
