Mortality figures were calculated for a group of 717 Dutch haemophiliacs over the period 1973-86. Follow-up was on average 10.9 years; no patients were lost to follow-up. The data were compared to the general male population by actuarial methods and patient-year analysis. Forty-three patients died, while 20 deaths were expected in a hypothetical group of non-haemophiliacs of the same age distribution. Hence, overall mortality was 2.1 times higher than in the general population. This leads to a calculated life expectancy of 66 years, as compared to 74 years in the general male population. Mortality did not differ much by severity of haemophilia. A possibly beneficial effect of prophylaxis on longevity was observed. Haemorrhage occurred in half of all deaths and among these traumatic bleeding was the most prevalent. The number of deaths due to ischaemic heart disease was significantly lower (80% reduction) than expected and therefore the authors conclude that haemophilia offers protection against ischaemic heart disease. Cancer mortality was significantly higher (2.5 times) than expected.
