beta-Blockers have generally demonstrated smaller reductions in cardiovascular events, compared with other anti hypertensive classes, despite similar reductions in blood pressure. This may be due to the ineffectiveness of traditional beta-blockers, such as atenolol, in reducing central aortic pressure, a strong, independent predictor of cardiovascular outcome. However, the beta-blocker class is heterogeneous, and some newer beta-blockers; which exhibit vasodilatory effects independent of beta-blockade, provide beneficial effects on arterial stiffness and endothelial dysfunction which may lead to reductions in central aortic pressure and improvements in clinical outcomes. For example, the vasodilating beta-blocker nebivolol was shown to improve forearm blood flow and arterial stiffness and; in a large clinical study, to significantly reduce morbidity and mortality, independent of left ventricular;ejection fraction, among patients with chronic heart failure. Further research is warranted to investigate any, potential :differences between Traditional and newer vasodilating beta-blockers on cardiovascular outcomes.
