Of 6933 patients, 197 (2.8%) died during a follow-up of 24 865 patient-years. Compared with the general national population, there was excess mortality, particularly in the young. Median age at death was 48.8 years. Of all deaths, 77% had a cardiovascular origin; 45% were due to chronic heart failure (26%, age 51.0 years) or sudden death (19%, age 39.1 years). Age predicted…
