Angiotensin-converting enzyme inhibitors (ACEi) and angiotensin receptor blockers (ARBs) improved cardiac function in acromegaly patients with hypertension. These medications may offer cardiac benefits in acromegaly, warranting further investigation.
Area of Science:
- Cardiology
- Endocrinology
Background:
- Acromegaly is linked to a specific cardiomyopathy with unclear pathogenesis.
- The renin-angiotensin system blockade (ACEi/ARBs) improves cardiac outcomes post-myocardial infarction and in heart failure.
Purpose of the Study:
- To compare cardiac indices in acromegaly patients with varying hypertension status and medication use.
- To investigate the potential cardiac benefits of ACEi/ARBs in acromegaly.
Main Methods:
- Cardiac magnetic imaging was used to assess cardiac indices.
- Patients were categorized into three groups: active acromegaly without hypertension, hypertension without ACEi/ARBs, and hypertension with ACEi/ARBs.
Main Results:
- Patients on ACEi/ARBs exhibited significantly lower end-diastolic volume index (EDVi) and end-systolic volume index (ESVi) compared to the other groups.
- Acromegaly patients with hypertension on ACEi/ARBs showed improved cardiac indices compared to those not on these medications.
Conclusions:
- ACEi/ARBs appear to improve cardiac indices in acromegaly patients with hypertension.
- Further research is needed to confirm the beneficial cardiac effects of ACEi/ARBs in acromegaly, even without overt hypertension.
