In another study focusing on stable angina patients undergoing elective PCI, intravenous landiolol administration did not differ from the control group in three-day post-PCI levels of adiponectin (APN) and high-molecular-weight APN, molecules thought to correlate with cardioprotection (e.g., bisoprolol has been shown to increase them, reducing myocardial damage) [32]. The gene discussed is ANPEP; the disease is angina pectoris.
