Atherosclerosis is a disease in which plaque builds up inside your arteries. Arteries are blood vessels that carry oxygen-rich blood to your heart and other parts of your body. Plaque is made up of fat, cholesterol, calcium, and other substances found in the blood. Over time, plaque hardens and narrows your arteries. This limits the flow of oxygen-rich blood to your organs and other parts of your body.
Atherosclerosis usually causes no symptoms until middle or older age. But as narrowings become severe, they choke off blood flow and can cause pain. Blockages can also suddenly rupture, causing blood to clot inside an artery at the site of the rupture. Once a blockage has developed, it's generally there to stay. With medication and lifestyle changes, though, plaques may slow or stop growing. They may even shrink slightly with aggressive treatment.
Lifestyle changes: Reducing the lifestyle risk factors that lead to atherosclerosis will slow or stop the process. That means a healthy diet, exercise, and no smoking. These lifestyle changes won't remove blockages, but they’re proven to lower the risk of heart attacks and strokes. Medication: Taking drugs for high cholesterol and high blood pressure will slow and perhaps even halt the progression of atherosclerosis, as well as lower your risk of heart attacks and stroke. The Statistics of the extrapolated prevalence of Atherosclerosis in Japan is 2,164,661 in an total estimated population of 127,333,002.
