not receive enough oxygen-rich blood. This is known as angina.
2. Shortness of Breath
Narrowed coronary arteries can reduce blood flow to the heart and may cause shortness of breath, particularly during physical activity. Shortness of breath can have many other causes, so it should not automatically be attributed to clogged arteries.

Unexplained fatigue can sometimes accompany reduced blood flow to the heart. In particular, some people with heart disease may experience unusual tiredness rather than typical chest pain.
