Heart rate is a major determinant of myocardial oxygen consumption and of cardiac work, and
thus reduction of heart rate may represent an important strategy for the treatment of patients
with a wide range of cardiac disorders. In addition, several experimental lines of research point
to high heart rate as an important risk factor for atherosclerosis and, thus, pharmacologic heart
rate reduction could prevent or retard the development of atherosclerotic plaques and increase
survival. Today, in patients with acute or chronic coronary syndromes or with congestive heart
failure, reducing heart rate is a generally accepted treatment modality. Up to now, no human
study has been performed to demonstrate the efficacy and the risk-benefit ratio of cardiac
slowing in patients without cardiac disorders. However, recent retrospective analyses of the
INternational VErapamil-SR/trandolapril STudy and the Paris Prospective Study 1 provided
promising results. Treatment of high heart rate in healthy subjects appears to be premature, but
in clinical conditions such as hypertension or diabetes, the reduction of elevated heart rate
appears a desirable additional goal of therapy. (Prog Cardiovasc Dis 2009;52:46-60)
