Abstract
Although coronary revascularization procedures are widely performed in patients with coronary artery disease (CAD), angina is often reported, even after such procedures. This study evaluated the antianginal efficacy and effect of ivabradine treatment on quality of life (QOL) in patients with CAD and history of coronary revascularization. This is a post hoc analysis (926 post-revascularization patients) of a prospective, noninterventional study, which included 2403 patients with CAD and stable angina. The data were recorded at baseline, at 1 month and 4 months after inclusion. After ivabradine administration, mean number of anginal events decreased from 2.2 ± 2.3 (median: 2.0, minimum: 0.0, maximum: 21.0, range: 21.0) to 0.3 ± 0.6 (median: 0.0, minimum: 0.0, maximum: 7.0, range: 7.0) times/week (P < .001), while nitroglycerin consumption decreased from 1.5 ± 2.2 (median: 1.0, minimum: 0.0, maximum: 20.0, range: 20.0) to 0.1 ± 0.4 times/week (median: 0.0, minimum: 0.0, maximum: 5.0, range: 5.0; P < .001). Quality of life improved at study completion compared to baseline (P < .001). Ivabradine addition on top of optimal individualized dose of β-blockers is associated with decreased anginal events and improvement in QOL in patients with stable angina and history of coronary revascularization.
