Patients with long-term heart failure could have their life expectancy improved by a new type of pacemaker. A US study which followed 1,500 patients found those who had a device implanted were less likely to be admitted to hospital, or to die. Around 900,000 people in the UK are thought to be living with long-term heart failure. The research, led by the University of Colorado, is published in the New England Journal of Medicine.
