O'Brien J, et al. - Previous studies of patients with heart failure and coronary artery disease have suggested that worse cardiovascular outcomes are seen in those with higher resting heart rates (HR), so researchers assessed if HR immediately prior to percutaneous coronary intervention (PCI) independently predicts 30-day outcome. Analysis of the outcome of 3,720 patients, who had HR recorded prior to PCI from the Melbourne Interventional Group registry suggests that HR immediately prior to PCI independently predicts adverse 30-day cardiovascular outcomes. Higher HR was noted more frequently among patients who were female, current smokers, have higher systolic and diastolic blood pressure, atrial fibrillation, recent heart failure, lower ejection fraction, and ST-elevation myocardial infarction (MI) as the indication for the PCI.
