Coronary

 In cardiology, “coronary flow slowness” usually refers to the Coronary Slow Flow Phenomenon, and “ANOCA” refers to Angina with Non‑Obstructive Coronary Arteries. They’re closely related.

Coronary Slow Flow Phenomenon (CSF)

• Blood moves slowly through coronary arteries on angiography
• No major blockage is seen
• Thought to involve microvascular dysfunction (tiny vessels not working properly)
• Symptoms:
• Chest pain (angina)
• Shortness of breath
• Sometimes palpitations
• ECG and stress tests may look like ischemia even without blockage

ANOCA (Angina with Non-Obstructive Coronary Arteries)

This is a broader category:

• Patient has angina symptoms
• Angiogram shows no significant stenosis
• Causes include:
• Coronary slow flow
• Microvascular angina
• Vasospasm (Prinzmetal-type)
• Endothelial dysfunction

So:

• Coronary slow flow = one specific mechanism
• ANOCA = umbrella diagnosis that can include coronary slow flow

Why it matters

These patients still have real ischemia, even without blockages. Treatment may include:

• Calcium channel blockers
• Nitrates
• Beta blockers (case-dependent)
• Statins
• Lifestyle changes (stress, smoking, etc.)
