Cardiac cephalgia

Area of Science:

• Neurology
• Cardiology
• Emergency Medicine

Background:

• Cardiac cephalgia is classified as a secondary headache (ICD-10 code 10.6) linked to homeostatic disorders.
• It is often an underdiagnosed condition, potentially being the only presenting symptom of an acute coronary event in 27% of cases.
• This headache type typically arises post-exertion and can present with diverse, non-specific clinical features.

Purpose of the Study:

• To critically evaluate the existing medical literature on cardiac cephalgia.
• To highlight the diagnostic challenges and clinical variability associated with this condition.
• To increase awareness of cardiac cephalgia as a potential indicator of ischemic cardiovascular events.

Main Methods:

• Comprehensive review of medical literature concerning cardiac cephalgia.
• Analysis of diagnostic criteria and clinical presentations.
• Examination of cases where headache was the sole manifestation of cardiac events.

Main Results:

• Cardiac cephalgia presents with high variability, mimicking migraine or tension-type headaches.
• Routine cardiac investigations (enzymes, ECG, stress tests) can be negative, necessitating coronary angiography for definitive diagnosis.
• Key indicators for suspicion include older age, no prior headache history, vascular risk factors, and exertional onset.

Conclusions:

• Cardiac cephalgia is a challenging diagnosis due to its mimicry of primary headaches and variable presentation.
• Increased clinical suspicion and awareness are crucial, especially in patients with cardiovascular risk factors presenting with new-onset exertional headaches.
• Further research and recognition are needed to improve the understanding and management of this potentially life-threatening condition.
