Chest pain with normal coronary angiograms, known as INOCA (Ischemia with Non-Obstructive Coronary Arteries), affects up to 30% of patients. This review explores the coronary causes, diagnostic strategies, and treatments for INOCA.

Area of Science:

  • Cardiology
  • Vascular Medicine

Background:

  • Angina with normal coronary angiograms (NOCAD) affects 20-30% of patients.
  • NOCAD etiologies include epicardial disease, coronary microvascular dysfunction, and noncoronary conditions.

Purpose of the Study:

  • To review the coronary etiologies of NOCAD.
  • To discuss pathophysiology, diagnostic strategies, and therapeutic options for NOCAD.

Main Methods:

  • Literature review focusing on coronary causes of NOCAD.
  • Discussion of diagnostic pathways and treatment modalities.

Main Results:

  • Coronary etiologies include endothelial dysfunction, coronary artery spasm, and coronary artery bridging.
  • Microvascular dysfunction can stem from various systemic conditions.

  • Noncoronary factors can also present as NOCAD.

    • Conclusions:

    • Understanding the coronary causes of NOCAD is crucial for accurate diagnosis.
    • A systematic approach aids in identifying the underlying pathophysiology.
    • Effective therapeutic strategies can improve patient prognosis.
