A 90% blockage leaves about one-tenth.<\/span><\/p>\n<p><b>Why Two Reports Can Show Different Numbers<\/b><\/p>\n<p><span style=\"font-weight: 400;\">The number is often a visual estimate made while watching the angiography video. Two experienced cardiologists can estimate the same artery differently.<\/span><\/p>\n<p><b>CT coronary angiography<\/b><span style=\"font-weight: 400;\"> can also read higher than catheter angiography when arteries have a lot of calcium.

It may not significantly restrict blood flow, but it is not considered completely normal.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Small plaque still matters. Heart attacks can occur when plaque ruptures and a clot blocks the artery.
