Glucocorticoid excess syndromes causing hypertension

Area of Science:

• Endocrinology
• Cardiovascular Medicine
• Pharmacology

Background:

• Adrenal glucocorticoids are vital for physiologic functions, including blood pressure regulation.
• Sustained excess, as seen in Cushing's syndrome or prolonged steroid therapy, triggers adverse cardiovascular effects.
• These effects include arterial hypertension and arteriosclerotic cardiovascular disease via multiple pathogenic pathways.

Purpose of the Study:

• To review the detrimental cardiovascular consequences of sustained glucocorticoid excess.
• To emphasize the importance of early diagnosis and management of conditions like Cushing's syndrome.
• To explore future therapeutic strategies for glucocorticoid-related cardiovascular toxicity.

Main Methods:

• Review of existing literature on glucocorticoid physiology and pathology.
• Analysis of pathogenetic mechanisms linking glucocorticoid excess to cardiovascular disease.
• Discussion of clinical implications for Cushing's syndrome and steroid therapy.

Main Results:

• Glucocorticoid excess is a significant risk factor for hypertension and arteriosclerotic cardiovascular disease.
• While beneficial for immunosuppression and inflammation, glucocorticoid therapy carries cardiovascular risks.
• Naturally occurring Cushing's syndrome is often treatable if detected early, barring metastatic malignancy.

Conclusions:

• Minimizing steroid dosage and exploring non-steroid alternatives are crucial for mitigating cardiovascular risks.
• Development of specific steroids with reduced cardiovascular toxicity is a promising future direction.
• Balancing the therapeutic benefits of glucocorticoids with their cardiovascular risks requires careful management.
