title: Comparison of effectiveness of cardiac resynchronization therapy in patients <70 versus > or =70 years of age.
abstract: In the present study, the effects of cardiac resynchronization therapy (CRT) in elderly patients were evaluated. The study included 170 consecutive patients whose clinical and echocardiographic improvements were evaluated after 6 months of follow-up. Survival was evaluated up to 2 years. The effects of CRT in elderly patients (age > or =70 years) were compared with those in younger patients (age <70 years).
