The scarred tissue also impedes the contraction and makes the pumping even weaker, and it does not conduct electrical current like the normal muscles.

This narrows or blocks the artery and can cause a heart attack because blood flow cannot reach the heart muscle. Spontaneous coronary artery dissection (SCAD) is an uncommon occurrence, but because it occurs spontaneously, itâs important to recognize the symptoms and get treatment immediately.
