Answer:
Coronary heart disease
Explanation:
Hi, i'm not completely sure I understand the question that you are asking. If you are asking for a medical condition that affects blood flow in the heart - Coronary heart disease.
This puts an increased strain on the heart, and can lead to: angina – chest pain caused by restricted blood flow to the heart muscle, heart attacks – where the blood flow to the heart muscle is suddenly blocked., heart failure – where the heart is unable to pump blood around the body properly. Which if untreated can lead to death. 
I have posted the link to the NHS website with some great info on it.
