Key Points

To evaluate whether lowering resting heart rate provides a direct physiological and clinical mechanism of cardiovascular benefit.
Reviewed physiological and clinical evidence examining the impact of heart rate lowering on cardiac workload and hemodynamics.
Assessed hemodynamic parameters including myocardial oxygen consumption, coronary blood flow, and ventricular mechanics.
Lowering heart rate extends diastolic filling and perfusion time, improving blood delivery to the myocardium.
Heart rate reduction decreases myocardial oxygen consumption and mechanical wall stress, enhancing overall cardiac efficiency.
