Corony Artery Disease
Artery Disease: Artery disease is the broad term for the disease of narrowing of the blood vessels caused by the buildup of plaque. Most applied to the blood vessels that supply the heart, hence the term coronary artery disease (cad). It is assumed if you have narrowing of the vessels within the heart, then you have artery disease throughout your body. Artery disease is a risk factor for heart attacks and stroke. ...Read moreSee 1 more doctor answer
Arteries are defined as blood vessels which carry blood away from the heart (to either the body or lungs). Arteries: higher pressure, thicker walls, stretch (pulse) with each heart contraction & deliver blood to the arterioles which control the flow to individual capillaries. Veins are blood vessels which carry blood from capillaries back to the heart (body to right heart; ...Read more
Carotid Art Disease: Your carotid arteries are two large blood vessels in your neck. They supply your brain with blood. If you have carotid artery disease, the arteries become narrow, usually because of atherosclerosis. This is the buildup of cholesterol and other material in an artery. If a blood clot sticks in the narrowed arteries, blood can't reach your brain. This is one of the causes of stroke. ...Read more
They are different: The first symptoms of alzheimer's disease you may notice are increasing forgetfulness and mild confusion. Over time, the disease has a growing impact on your memory, your ability to speak and write coherently, and your judgment and problem solving. Dementia is a serious loss of global cognitive ability in a previously unimpaired person, beyond what might be expected from normal aging. ...Read more
Plaque vs. Occlusion: Large artery disease is plaque within the walls (not the openings) of the vessel. Small vessel disease typically refers to capillaries, ~5 micron id, closing off, due to plaque ruptures/clots shedding from the larger upstream arteries or capillary endothelial cell damage & closure most commonly seen in advanced diabetes mellitus. Drivers for both are similar: lipoproteins, blood sugar, bp, smoking. ...Read more
Atherosclerosis: Plaque is an accumulation of white blood cells, mostly macrophages, within the wall of the arteries, never veins. The wbcs are eating oxidized LDL particles (not cholesterol) in the wall & HDL particles can help prevent/regress ds. It typically begins in childhood, though asymptomatic for decades. Drivers sugar/carb foods, ?ldl (nmol/l), ?hdl (umol/l), ?bld sugar (optimal hba1c 5.0%), ?bp obesity. ...Read more
Vary Widely: The symptoms can include pain, numbness, weakness, wounds, gangrene, or slow healing of the affected extremity. The most common early sign is claudication, which is defined as muscle discomfort or cramping brought on by exercise & relieved with rest. Chronic pain in the leg or foot, often a achiness or burning, is also common. Get testing w/ ultrasound or blood pressures of the legs by vascular MD ...Read moreSee 1 more doctor answer
Narrowed arteries: Peripheral artery disease refers to a condition in which your leg arteries become narrowed due to atherosclerosis which limit the blood flow to your legs. It is usually rare in people that are less than 40 years of age but depending on risk factors and family history one can develop it earlier. Can be diagnosed by taking blood pressure at your legs and comparing it to the arms. ...Read moreSee 2 more doctor answers
Artery Disease Legs: Peripheral artery disease, or "pad" is a blood vessel condition that is usually the result of progressive plaque build-up within the walls of arteries than leads to blockage of blood flow. It can cause leg pain when walking, usually in the calves, pain at rest in the foot or leg, leg numbness or tinlging, coldness or discoloration of the skin, foot or leg ulcers, gangrene, poor healing of wounds. ...Read moreSee 2 more doctor answers
Yes, Work on Issues: Plaque ruptures shedding debris & inducing clots are what drive cardiovascular events; why the problem does not show well on angiograms; much less stress tests (really blind to problem). Exercise increases pulse pressure; artery stretching & relaxing with each heart beat, thus ?ing frequency of plaque ruptures. Yet most don't do enough damage to produce obvious symptoms. ? my answers on ds drivers. ...Read moreSee 1 more doctor answer
