For many years, doctors have thought that the most reason behind a coronary failure or stroke or was the buildup of fatty plaque at intervals Associate in Nursing artery, resulting in the center or brain. In time, the plaque buildup would cut the artery most, that the artery would shut off or become clogged by a blood. the shortage of oxygen-rich blood to the center would then result in a coronary failure. but these kinds of blockages cause solely regarding three out of ten heart attacks.
Researchers area unit finding folks that that heart attacks don't have arteries severely narrowed by plaque! Vulnerable plaque is also buried within the artery wall, and not pop out and block the blood flow through the artery. this can be why researchers began to appear at however inflammation affects the arteries, and to envision if inflammation could lead on to a coronary failure.
What they found was that inflammation ends up in the event of "soft" or vulnerable plaque. They conjointly found that vulnerable plaque was over simply dust, preventative Associate in Nursing artery, that it had been stuffed with completely different cell varieties that facilitate with clotting.
When this inflammation is combined with alternative stresses, like high vital sign, it will cause the skinny covering over the plaque to crack and bleed, spilling the complete contents of the vulnerable plaque into the blood. The sticky cytokines on the artery wall capture blood cells (mainly platelets) that rush to the location of injury. once these cells clump along, they'll type a clot giant enough to dam the artery
