Hypopituitarism has been associated with 1.8-fold higher mortality compared with an age- and sex-matched population.[8]Rosén T, Bengtsson BA. Premature mortality due to cardiovascular disease in hypopituitarism. Lancet. 1990 Aug 4;336(8710):285-8.

Cardiovascular and cerebrovascular death rates are higher in patients with hypopituitarism compared with the general population.[7]Nilsson B, Gustavasson-Kadaka E, Bengtsson BA, et al. Pituitary adenomas in Sweden between 1958 and 1991: incidence, survival and mortality. J Clin Endocrinol Metab. 2000 Apr;85(4):1420-5.

Growth hormone deficiency is potentially responsible for increased cardiovascular mortality.[10]Gazzaruso C, Gola M, Karamouzis I, et al. Cardiovascular risk in adult patients with growth hormone (GH) deficiency and following substitution with GH--an update. J Clin Endocrinol Metab. 2014 Jan;99(1):18-29.

However, it is likely that there is a multi-factorial aetiology to excess mortality in these patients.[92]Bates AS, Van't Hoff W, Jones PJ, et al. The effect of hypopituitarism on life expectancy. J Clin Endocrinol Metab. 1996 Mar;81(3):1169-72.

Age at diagnosis, female sex, and craniopharyngiomas were all significant independent risk factors for excess mortality in one study.[93]Tomlinson JW, Holden N, Hills RK, et al. Association between premature mortality and hypopituitarism. West Midlands Prospective Hypopituitary Study Group. Lancet. 2001 Feb 10;357(9254):425-31.
