In patients with suspected and established coronary artery disease, an elevated heart rate is an independent predictor of survival [8–11]. This could be particularly useful in patients who are unable to tolerate beta-blockers or non-dihydropyridine calcium channel inhibitors. Beta blockers are no longer the first line of defense used to lower blood pressure. inhibitor is likely to become another useful group of medicine in cardiovascular disease management in the near future.
