Introduction Cardiac Emergencies

Cardiac emergencies are critical situations involving the heart that require immediate medical intervention to prevent severe complications or death. These emergencies often arise from underlying heart conditions that impair the heart's ability to function correctly.Types of Cardiac EmergenciesThe most common types of cardiac emergencies include Acute Coronary Syndrome (ACS), myocardial infarction (MI), cardiac arrest, and heart failure.Acute Coronary Syndrome (ACS)Acute Coronary Syndrome (ACS)...

Summary
This summary is machine-generated.

Sentinel headache (SH), a sudden, intense headache, preceded subarachnoid hemorrhage (SAH) in 27% of patients. Further research is needed to identify SH predictors and improve outcomes for cerebral aneurysm patients.

Area of Science:

  • Neurology
  • Neurosurgery
  • Emergency Medicine

Background:

  • Sentinel headache (SH) is a secondary headache characterized by sudden, intense, and persistent pain.
  • SH often precedes spontaneous subarachnoid hemorrhage (SAH) by days or weeks.

Purpose of the Study:

  • To determine the prevalence of sentinel headache (SH) in patients with spontaneous subarachnoid hemorrhage (SAH).
  • To identify potential factors associated with the occurrence of SH before SAH.

Main Methods:

  • Eighty-nine consecutive patients diagnosed with spontaneous SAH were evaluated.
  • Data collected included patient demographics, medical history, and clinical presentation upon admission.

Main Results:

  • The prevalence of SH was 27.0% among the 89 SAH patients.
  • SH occurred an average of 10.6 days prior to SAH.
  • No statistically significant differences were found regarding SH presence and gender, hypertension, migraine, or neurological scales (GCS, WFNS).

Conclusions:

  • Sentinel headache (SH) affects over a quarter of spontaneous subarachnoid hemorrhage (SAH) patients.
  • No specific related factors were identified in this study.
  • Further research is crucial to better understand SH for improved diagnosis and patient prognosis in neurovascular emergencies.
