Neurocirculatory asthenia — Clinical Guidelines

Overview

Neurocirculatory asthenia, also known as chronic asthenic syndrome, is characterized by persistent complaints of fatigue, palpitations, dyspnea, and anxiety without identifiable organic pathology. It shares symptoms with conditions like mitral valve prolapse, though recent evidence suggests they are unrelated 3.

Diagnosis

Clinical Symptoms: Fatigue, palpitations, dyspnea, anxiety 3.

Exclusion of Organic Causes: Comprehensive cardiac evaluation including echocardiography to rule out mitral valve prolapse 3.

ECG Changes: May show nonspecific ST-T changes; differentiation from ischemic changes can be aided by adrenergic blockade tests 4.

Differential Diagnosis: Distinguish from mitral valve prolapse and other cardiac conditions through echocardiography and auscultation 3.

Management

Symptom Management: Focus on reassurance, lifestyle modifications, and psychological support 4.

Beta-Blockers: Propranolol may improve ECG changes and symptoms, suggesting a role in managing sympathetic overactivity 4.

Psychological Therapy: Cognitive-behavioral therapy and stress management techniques can be beneficial 4.

Special Populations

No Specific Guidance: Limited data on neurocirculatory asthenia in pregnancy, pediatrics, or elderly populations from provided abstracts 1 3 4.

Key Recommendations

Exclude Organic Causes: Perform echocardiography and thorough cardiac evaluation to rule out mitral valve prolapse and other cardiac conditions (Evidence: Moderate 3).

Consider Beta-Blockade: Use propranolol to evaluate and potentially manage ECG changes and symptoms indicative of sympathetic overactivity (Evidence: Weak 4).

Psychological Support: Implement cognitive-behavioral therapy and stress management as adjunctive treatments (Evidence: Expert opinion 4).
