Is blood pressure affected by angina attacks

yes there is an effect on the blood prassure in angina attack...because there is less blood to the cardiac muscles due to plaque..so the heart can not contract properly..which leads to circulation failure or low output cadiac failure

The response is variable. In usual anginal attacks, blood pressure goes up due to sympathetic overactivity and adrenaline release in response to pain.

But rarely a large portion of the heart can become ischemic (reduced blood supply) so that pumping force of the heart can be reduced. In such an instance, blood pressure will come down.
