Insights

About half of acute ischemic stroke (AIS) patients have elevated high-sensitivity cardiac troponin (hs-cTn) levels, increasing cardiac risks. A standardized algorithm and expert collaboration are crucial for diagnosing diverse causes of troponin elevation in AIS.

Area of Science:

  • Cardiology
  • Neurology
  • Biochemistry

Context:

  • Elevated high-sensitivity cardiac troponin (hs-cTn) is common in acute ischemic stroke (AIS).
  • These patients face increased risks of morbidity and mortality, often cardiac-related.
  • Identifying the cause of hs-cTn elevation is critical for appropriate management.

Purpose:

  • To present a practice-oriented approach for the differential diagnosis of hs-cTn elevation in AIS patients.
  • To update the Mannheim clinical algorithm for managing troponin elevation in acute ischemic stroke.
  • To emphasize the need for a multidisciplinary approach involving cardiologists and neurologists.

Summary:

  • Approximately 50% of AIS patients exhibit elevated hs-cTn levels.
  • Most hs-cTn elevations in AIS are due to non-ischemic myocardial injury.
  • Causes are diverse, sometimes silent, and can include life-threatening conditions like myocardial infarction.

Impact:

  • Facilitates accurate diagnosis and timely intervention for cardiac complications in AIS.
  • Improves patient outcomes by guiding appropriate work-up and treatment strategies.
  • Provides a standardized clinical algorithm for healthcare professionals managing AIS patients with elevated troponin.
