Insights
Disease control and lifestyle choices significantly predict cardiovascular risks and comorbidities in acromegaly patients. Effective acromegaly management is key to reducing major adverse cardiovascular events (MACE).
Area of Science:
- Endocrinology
- Cardiology
- Internal Medicine
Background:
- Acromegaly, a condition of excess growth hormone, is associated with increased risks of comorbidities and cardiovascular events.
- Identifying predictors for these complications is crucial for patient management.
Purpose of the Study:
- To identify predictors of comorbidities (diabetes, hypertension) and major adverse cardiovascular events (MACE) post-acromegaly diagnosis.
- To evaluate the impact of acromegaly treatment on these complications.
Main Methods:
- Retrospective cohort study of 200 acromegaly patients.
- Outcomes assessed: diabetes, hypertension, MACE.
- Patients classified by treatment: post-adenomectomy (Hx), somatostatin analogue controlled (SSAc), or uncontrolled (SSAnc).
- Cox regression analysis used for data evaluation.
Main Results:
- Diabetes developed in 40.8% of patients; uncontrolled SSA (SSAnc) group showed higher risk (HR: 3.32).
- Hypertension occurred in 35.5%; age and BMI were significant predictors.
- MACE occurred in 11.8%; age and smoking were predictors.
- Acromegaly therapy did not significantly influence hypertension or MACE rates.
Conclusions:
- Disease control, regardless of treatment type, is a predictor of comorbidities and MACE in acromegaly.
- Lifestyle factors, such as smoking, also play a significant role in cardiovascular risk.
Objective:
The primary objective of this study is to identify the predictors of comorbidities and major adverse cardiovascular events (MACE) that can develop after diagnosis of acromegaly. The role of therapy for acromegaly in the event of such complications was also evaluated.
Design And Methods:
Retrospective cohort study was conducted on 200 consecutive acromegalic patients in a tertiary referral center. The following outcomes were evaluated: diabetes, hypertension and MACE. Each patient was included in the analysis of a specific outcome, unless they were affected when acromegaly was diagnosed, and further classified as follows: (i) in remission after adenomectomy (Hx), (ii) controlled by somatostatin analogues (SSA) (SSAc) or (iii) not controlled by SSA (SSAnc). Data were evaluated using Cox regression analysis.
Results:
After diagnosis of acromegaly, diabetes occurred in 40.8% of patients. The SSAnc group had a three-fold higher risk of diabetes (HR: 3.32, P = 0.006), whereas the SSAc group had a 1.4-fold higher risk of diabetes (HR: 1.43, P = 0.38) compared with the Hx group. Hypertension occurred in 35.5% of patients, after diagnosis. The determinants of hypertension were age (HR: 1.06, P = 0.01) and BMI (HR: 1.05, P = 0.01). MACE occurred in 11.8% of patients, after diagnosis. Age (HR: 1.09, P = 0.005) and smoking habit (HR: 5.95, P = 0.01) were predictors of MACE. Conversely, therapy for acromegaly did not influence hypertension or MACE.
Conclusion:
After diagnosis of acromegaly, control of the disease (irrespective of the type of treatment) and lifestyle are predictors of comorbidities and major adverse cardiovascular events.
