Does the heart grow new veins around blocked areas?

The heart does not grow new veins around blocked areas. When a coronary artery becomes blocked, it can lead to a heart attack, which damages the heart muscle. The heart cannot repair itself, and the damaged tissue is replaced by scar tissue. This scar tissue does not contain any blood vessels, so the heart muscle in the affected area does not receive any oxygen or nutrients. This can lead to heart failure.

There are a number of treatments that can be used to improve blood flow to the heart, including bypass surgery and angioplasty. These treatments can help to relieve the symptoms of heart disease and prevent heart failure.
