[Hypertension and acromegaly in the elderly: French Registry Data].

UNLABELLED

Multi centre registries such as the French Acromegaly Registry created in 1999 provide data on rare disorders that are otherwise difficult to obtain. This study focuses on the characteristics of high blood pressure in people aged of over 70 years old.

PATIENTS AND METHODS

The data were obtained from the thirty centres where patients had been recorded on the Acromegaly Registry since 1999.

RESULTS

The Register listed a total of 644 patients with acromegaly at January 1st 2005, of whom 68 (22 men and 46 women) were aged over 70 years old (10.6%). Their mean age was 76.8 +/- 5 years (range 70 - 95) and they had been presenting acromegaly for 11 +/- 6 years (compared to 7 years in those aged less than 70). Their BMI were 27.9 +/- 4 kg/m2 for men, 27.7 +/- 4 for women (respectively 28.4 +/- 4.3 and 26.7 +/- 4.4 in those aged less than 70 years). Hypertension was particularly frequent in this population, reaching 80% vs. 27% under 70 years (p=0.0001). Prevalence was then higher than in general population (referring to FLAHS study). Mean blood pressure was 143 +/- 12 / 84 +/- 15 mmHg for men and 141 +/- 17 / 79 +/- 9 for women. 46% of men and 30% of women treated or not, had blood pressure over 140 / 90 mmHg. Data showed 12% of arrhythmic cardiopathy, 8% of cardiac insufficiency, 12% of ischemic cardiopathy and 12% of patients suffering from arteritis or stroke. Although various therapeutic strategies had been applied for young and elderly patients, 51% in each group were in remission one year after inclusion.

DISCUSSION

More than 10% of patients are aged over 70 years in the French Acromegaly Registry and hypertension is very frequently observed in this population. The increasing life expectancy due to currently available treatments justifies a strict management of patients in order to reduce cardiovascular risks, which stay the main cause of morbidity and mortality.
