Do heart blockages always require surgery?

For some people, medications and lifestyle changes may be the treatment of choice — especially if only one artery is narrowed. In others, angioplasty may be recommended to open the clogged arteries — especially if chest pain (angina) due to reduced blood flow has not improved with medication and lifestyle changes.

How much blockage is normal?

A moderate amount of heart blockage is typically that in the 40-70% range, as seen in the diagram above where there is a 50% blockage at the beginning of the right coronary artery. Usually, heart blockage in the moderate range does not cause significant limitation to blood flow and so does not cause symptoms.

Can heart block cause a stroke?

Having any form of heart block raises your risk for other abnormal heart rhythms (arrhythmias). Arrhythmias can lead to stroke and other complications.
