Atherosclerosis is the buildup of fats, cholesterol and other substances in and on your artery walls. This buildup is called plaque. The plaque can cause your arteries to narrow, blocking blood flow. The plaque can also burst, leading to a blood clot.

Atherosclerosis -- sometimes called hardening of the arteries -- can slowly narrow the arteries throughout your body. When atherosclerosis affects arteries that carry blood to the heart muscle, it's called coronary artery disease, or CAD.
Risk factors for coronary artery disease include:Age. Getting older increases your risk of damaged and narrowed arteries.Sex. Men are generally at greater risk of coronary artery disease. ... Family history. ... Smoking. ... High blood pressure. ... High blood cholesterol levels. ... Diabetes. ... Overweight or obesity.More items...•
Depending on the results of the physical exam, your doctor may suggest one or more tests, including:Blood tests. ... Electrocardiogram (ECG or EKG). ... Exercise stress test. ... Echocardiogram. ... Doppler ultrasound. ... Ankle-brachial index (ABI). ... Cardiac catheterization and angiogram. ... Coronary calcium scan.More items...•
Atherogenesis can be divided into five key steps, which are 1) endothelial dysfunction, 2) formation of lipid layer or fatty streak within the intima, 3) migration of leukocytes and smooth muscle cells into the vessel wall, 4) foam cell formation and 5) degradation of extracellular matrix.
In your brain, this causes a stroke; in your heart, a heart attack. The plaques of atherosclerosis cause the three main kinds of cardiovascular disease: Coronary artery disease: Stable plaques in your heart's arteries cause angina (chest pain). Sudden plaque rupture and clotting cause heart muscle to die.
Coronary artery calcification (CAC) implies the presence of coronary artery disease (CAD) irrespective of risk factors or symptoms, is concomitant with the development of advanced atherosclerosis (1), and is an established predictor of future cardiac events 2, 3. Generally, CAC correlates with the extent of CAD.
'Coronary Artery Disease' (CAD)is often referred to as atherosclerosis. It affects the vessels, that supply blood to the heart muscle. It is caused by deposits of calcium, fat, cholesterol and fibrous tissues, which makes the lumen of arteries narrower.

Although blockages can occur in other arteries leading to the heart, the LAD artery is where most blockages occur.
A buildup of fatty plaques in your arteries (atherosclerosis) is the most common cause of coronary artery disease. Unhealthy lifestyle habits, such as a poor diet, lack of exercise, being overweight and smoking, can lead to atherosclerosis.
ASCVD is defined here as coronary artery disease (CAD), acute myocardial infarction (AMI), or ischemic stroke. The percentage of stays for ischemic stroke resulting in an in-hospital death decreased 38.1 percent from 2001 to 2014; in-hospital deaths also decreased 29.3 percent during this time among stays for AMI.

Generally, CAC correlates with the extent of CAD.
Coronary artery disease (CAD) is a condition which affects the arteries that supply the heart with blood. It is usually caused by atherosclerosis which is a buildup of plaque inside the artery walls.
'Coronary Artery Disease' (CAD)is often referred to as atherosclerosis. It affects the vessels, that supply blood to the heart muscle. It is caused by deposits of calcium, fat, cholesterol and fibrous tissues, which makes the lumen of arteries narrower.
