From a Harvard Medical School “Harvard Heart Letter”:
Chronic inflammation often begins with a similar cellular response but morphs into a lingering state that persists far longer. Toxins such as cigarette smoke or an excess of fat cells (especially around the belly area) can also trigger inflammation. So can the fatty plaque inside arteries, which causes inflammatory cells to cover and wall off the plaque from the flowing blood. But the plaque may rupture, mingle with blood, and form a clot. These clots are responsible for the majority of heart attacks and most strokes.
A buildup of cholesterol-rich plaque inside arteries — known as atherosclerosis — is the root cause of most heart attacks and strokes. Researchers have long recognized that chronic inflammation sparks this artery-damaging process (see “Understanding inflammation”). Now, they’re zeroing in on better ways to tackle that aspect of the problem.
Addressing inflammation is vital. Even when people take steps to lower their risks for heart disease, such as reducing their cholesterol and blood pressure, they may still face life-threatening cardiovascular events.
