High Blood Pressure
The external carotid arteries supply oxygen-rich blood to the face, scalp, and neck. Carotid artery disease can be very serious because it can cause a stroke, or brain attack.. A stroke occurs when blood flow to your brain is cut off. If blood flow is cut off for more than a few minutes, the cells in your brain start to die. This impairs the parts of the body that the brain cells control.  1 A heart attack is the result of a blocked blood supply to the heart muscle tissue. 2  This can happen when the arteries to the heart become thicker and harder from a buildup of plaque. 1 Heart failure is the term used for a heart that is not supplying sufficient blood flow to the rest of the body. 2  High blood pressure damages the entire complex circulatory system. 3  As mentioned above, HBP creates conditions for blocked arteries. 4  HBP adds to the workload of the heart. Carotid artery disease is serious because it can cause a stroke, also called a “brain attack.” A stroke occurs if blood flow to your brain is cut off. If blood flow is cut off for more than a few minutes, the cells in your brain start to die. This impairs the parts of the body that the brain cells control. Atherosclerosis can affect any artery in the body. For example, if plaque builds up in the coronary (heart) arteries, a heart attack can occur. If plaque builds up in the carotid arteries, a stroke can occur. A stroke also can occur if blood clots form in the carotid arteries. This can happen if the plaque in an artery cracks or ruptures Damaged and hardened arteries can lead to: 1  Damaged organs. 2  Damaged arteries cannot deliver adequate blood flow to the body's organs. 3  Blood clots. 4  When arteries are narrowed by fatty deposits, you have a greater risk for developing blood clots. 1 Heart failure is the term used for a heart that is not supplying sufficient blood flow to the rest of the body. 2  High blood pressure damages the entire complex circulatory system. 3  As mentioned above, HBP creates conditions for blocked arteries. 4  HBP adds to the workload of the heart. 1 HBP causes damaged and blocked arteries. 2  A heart attack is the result of a blocked blood supply to the heart muscle tissue. 3  This can happen when the arteries to the heart become thicker and harder from a buildup of plaque. 1 Heart failure is the term used for a heart that is not supplying sufficient blood flow to the rest of the body. 2  High blood pressure damages the entire complex circulatory system. 3  As mentioned above, HBP creates conditions for blocked arteries. 4  HBP adds to the workload of the heart. Atherosclerosis is a disease of the arteries in which fatty deposits called plaques or atheroma collect on the insides of the artery walls, leading to narrowing and obstruction of blood flow. This condition can affect all the arteries in the body. The coronary arteries (that is, arteries that supply the heart) can become blocked in various ways: by plaques forming around the walls, plaque can rupture and release fatty deposits that can block the arteries, or a blood clot can attach to the plaque.  1 High cholesterol can lead to blockage in the carotid artery that takes blood from the neck to the brain. 2  A piece of this plaque can break off and travel to the brain, causing a stroke. 3  Obesity can cause high blood pressure and high cholesterol. In some patients, atherosclerosis, specifically in the carotid artery in the neck, can lead to ischemic stroke. Plaque in the carotid artery may result in a stroke by either decreasing blood flow to the brain or by breaking loose and floating into a smaller vessel, depriving a portion of the brain of blood flow. Heart disease is a result of plaque buildup in your coronary arteries -- a condition called atherosclerosis -- that leads to blockages. The arteries, which start out smooth and elastic, become narrow and rigid, restricting blood flow to the heart. A. A. Coronary artery disease, also called coronary heart disease, or simply, heart disease, is the No. 1 killer in America, affecting more than 13 million Americans. Heart disease is a result of plaque buildup in your arteries, which blocks blood flow and heightens the risk for heart attack and stroke.
