Promising new technologies for heart failure are available

The annual mortality from chronic heart failure remains as high as 40%. In this week's clinical review, Chow and colleagues (p 1073) discuss the effects of new pacing technologies on patients with chronic heart failure. They report that the use of biventricular pacing improves symptoms and reduces the number of hospital admissions and lengths of stay. Implantable defibrillators reduce mortality, and forthcoming data from randomised controlled trials suggest that a wider range of patients should receive them. The authors outline the characteristics of patients who could benefit from these technologies and the complications that might arise.
