title: Cardiac risk in patients with treatment naïve, first-line medically controlled and first-line surgically cured acromegaly in comparison to matched data from the general population.
abstract: Coronary risk factors in patients with acromegaly after first-line transsphenoidal surgery (TSS) or first-line somatostatine analogue (SSA) treatment have rarely been examined. Aim of this study was an evaluation of cardiovascular risk factors and left ventricular hypertrophy (LVH) in 3 different patient groups with treatment naïve, active (ACT), first-line medically controlled (MED) and first-line surgically treated (SUR) acromegaly and a calculation of the Framingham Weibull Risk Score (FS).
  
  
  
  Retrospective comparative matched case-control study.
  
  
  
  40 acromegalic patients (cases aged 45-74 years, 23 men) were matched with respect to age and gender to 200 controls from the general population. 13 patients had treatment-naïve acromegaly (ACT), 12 patients were SSA treated (MED) and 15 patients were operated by TSS (SUR). Coronary risk factors were assessed after 12 months of treatment by interviews and direct laboratory measurements. Only patients normalized for IGF-I in MED and SUR group were included. FS and odds ratios (OR) from multiple conditional logistic regression (matched for age and gender, adjusted for BMI) were calculated.
  
  
  
  Compared to matched controls ACT patients had higher HbA1c levels (6.9±1.4 vs. 5.5±0.7% (p<0.0001)) and an increased prevalence of left ventricular hypertrophy (LVH) (30.8 vs. 3.2% (p=0.007). MED and SUR groups were similar for gender, age, disease duration and IGF-I levels at diagnosis. Compared to matched controls, MED patients had a significantly increased diastolic blood pressure (89±9 vs. 79±11 mmHg (p=0.001), prevalence of LVH (41.7 vs. 1.7% (p<0.0001), prevalence of diabetes mellitus (33.3 vs. 10.0% (p=0.03)), higher HbA1c levels (6.8±1.3 vs. 5.5±0.7% (p=0.0005)) and a higher FS (21.2±9.7 vs. 12.4±7.7% (p=0.002), OR 1.11 [1.02-1.21] (p=0.01)) while in the SUR group only higher prevalences of LVH (40.0 vs. 4.1% (p<0.0001)) and HbA1c levels (6.4±1.2 vs. 5.5±0.8% (p=0.006)) were found compared to controls.
  
  
  
  When comparing treatment naive, medically treated and surgically cured patients with acromegaly to age- and gender-matched subjects from the general population, we have found an increased cardiovascular risk in patients at 12 months after first-line SSA treatment but not in patients after first-line surgery.
