Previous studies have demonstrated a twofold to threefold increase in mortality in acromegalic patients largely due to increased cardiovascular disease, but also in some series due to increased malignant disease. In a retrospective analysis of 79 patients from one large hospital center in the United Kingdom, we sought to determine (1) whether the increased mortality persists and (2) what is the relationship between mortality and growth hormone (GH) levels achieved following treatment. Hospital records and death certificates were scrutinized and serum GH data collected from patients treated between 1967 and 1991. GH assessments were performed on average annually during follow-up evaluation and consisted of 3-hour measurements during waking hours in a GH day series. The average value was calculated from five readings. We used the lowest value, usually the most recent, for average GH achieved during the follow-up period. There were 29 males and 50 females, and no numerical difference between sexes was found in living and deceased groups. The mortality of the cohort was compared with that of the general population, and expected mortality was calculated from Office of Population Census Statistics data. The observed to expected ratio was determined. There were no differences between living and deceased groups in the proportion of subjects with hypertension, diabetes, or visual field defects at the time of diagnosis. Most patients were treated with radiotherapy +/- bromocriptine as primary therapy. There was a marked shift to lower mean GH values with treatment such that 48 of 79 had values less than 10 mU/L. Those subjects with mean GH levels less than 5 mU/L had significantly lower serum insulin-like growth factor-l (IGF-IJ values than subjects with values above this level. The observed to expected mortality ratios (with 95% confidence intervals in parentheses) were as follows: males, 2.55 (1.4-4.3), P =.002; females, 2.83 (1.6-4.8), P =.001; total, 2.63 (1.8-3.9), P
