Atherosclerosis is a disease that affects the arteries throughout the body, not just those in the coronary arteries. The condition occurs when a fatty material, known as plaque, builds up in the walls of the arteries, reducing their flexibility and making them narrower. This narrowing of the arteries reduces blood flow and can lead to a variety of issues, including heart attack, stroke, and aneurysm.
The primary cause of atherosclerosis is the accumulation of plaque in the artery walls due to a buildup of cholesterol, fats, cellular waste, and calcium. This buildup causes the artery walls to become stiff and narrow, leading to reduced blood flow.
The condition can occur in any major artery, including those in the neck, arms, abdomen, and legs. However, it is most commonly seen in the coronary arteries, which supply oxygenated blood to the heart. This is because these arteries are the most vulnerable to plaque buildup due to their critical role in providing oxygenated blood to the heart.
The most common symptom of atherosclerosis is chest pain, which is caused by the reduced blood flow to the heart. Other symptoms include shortness of breath, dizziness, fatigue, and palpitations. While these symptoms can vary in severity, they are all indicative of a narrowing of the arteries.
In conclusion, while atherosclerosis does most commonly occur in the coronary arteries, it can also affect other major arteries throughout the body. The condition is caused by a buildup of plaque in the walls of the arteries, which reduces blood flow and can lead to a variety of serious health issues.
