Coronary artery disease, or CAD, is the leading cause of death in the United States. It is identified by the slow progression of deposits to the artery walls which gradually narrow the lumen. The plaque not only limits the ability of blood flow, but hardens the elastic tissue of the vessel. This combination affects circulation and blood pressure.
Prevention is the best way to limit the effects of this disease, a healthy nutritional plan and adequate exercise are stressed for cardiovascular health and maintenance.

Which blood vessel supplies blood to the heart muscle?
The myocardium (muscle) that makes up the heart has its own blood supply called the coronary circulation. The coronary circulation comprises two main arteries; the left coronary artery and the right coronary artery. They branch off from the aorta (the biggest artery in the body!) really early on. The left coronary artery branches (into left marginal artery) to supply the left atrium and ventricle (chambers). The right coronary artery branches (into circumflex and left anterior descending) to supply the right atrium and ventricle and a bit of the left ventricle. Extra for experts: the way the coronary circulation is made up can change (just like people can be short or tall) because of genetic variability. So most people (about 70% off the top of my head) are "right dominant," because their right coronary artery branches to form the posterior interventricular artery. Some people are "left dominant" because their left coronary artery branches to form the posterior interventricular artery. So just remember Aorta --> left coronary artery --> left marginal --> right coronary artery --> circumflex + left anterior descending + the posterior interventricular artery from either left or right coronary artery Hope this helps :)
Can a car accident with seat belt damage cause a coronary artery to become blocked?
It will only do that if your too short. If the seatbelt isn't fastend properly then it can block your artery. You should have kids be in a booster seat if your worried about this.
What is the coronary artery in an adult?
There are two, the right and the left. They are the blood vessels that run directly out of the heart. One runs to the lungs to get oxygen and the other sends oxygenated blood into the body. ALSO: THEY ARE THE BLOOD VESSELS THAT SUPPLIES BLOOD TO THE HEART'S MUSCLES ---- The first answer above is incorrect. The coronary arteries are two in number, the right and the left. They arise from the proximal aorta, just after the aortic valve and supply blood directly to the cardiac muscle. The left has three main divisions: the left main coronary artery, which is the relatively short first segment. The left main then branches into the left anterior descending (LAD) and the left circumflex artery. The left artery supplies most of the septum and left side of the heart, including the left ventricle. The right coronary artery is a relatively smaller vessel and supplies the right side of the heart and the inferoposterior portion of the heart. It also supplies blood to the SA node and also to the AV node (in about 60% of patients).
How do atherosclerosis and hypertension affect the heart?
high blood preasure can cause atheromas and thrombosis, an athroma is like a baloon pushing out of the artery wall wich can pop and kill you, a thrombosis is a clot that forms on the artery wall that can loosen and flow into the heart or the conary artery leading to a heart attack
What is the name of the artery located on the bottom of the wrist that is used when taking a pulse?
That is the Volar Radial Carpal artery, or just Radial artery, for short.
What does the common celiac trunk branch into?
Gastric Artery - esophageal branch and hepatic Common Hepatic Artery - Proper hepatic artery, Right Gastric artery and Gastroduodenal artery Splenic Artery - Dorsal pancreatic, short gastric and Left Gastro-omental
What is the function of the gastric artery?
The four or five gastric arteries supply the lining of the stomach. The three main ones are called the left gastric artery, the right gastric artery and the short gastric artery.
What chamber does the pulmonary artery lead to?
The heart kind of looks like a royal crown. So in Latin, the word for crown (corona) was used to describe the heart. Thus, coronary means "pertaining to the heart". An artery is a blood vessel leading away from the heart toward another body part. This usually means that an artery is carrying fresh, red blood (oxygen-rich blood). So coronary artery means that fresh blood from inside the heart is being sent to the heart itself! This requires further explanation to those who are understandably confused by this.The coronary arteries are the blood vessels that supply the heart itself. The heart is a muscle that unselfishly pumps blood to the entire body 24/7- but the poor heart needs blood for itself in order to stay alive. The heart is made of muscle. Inside this muscle is a little system of blood vessels. The coronary artery feeds this heart muscle so that it can continue it's work.Blood has oxygen and nutrition in it as well as immune system components that help fight disease. All tissues of the body need all of these things to function and stay healthy. The heart is no exception- in fact, in the short-term, it's more crucial for the heart to get this stuff than most other tissues since it works so hard and is drastically affected by infections like those caused by streptococcus ("strep throat") bacteria.
Coronary artery balloon angioplasty - series?
Normal anatomyThe coronary arteries supply blood to the heart muscle. The right coronary artery supplies both the left and the right heart; the left coronary artery supplies the left heart.IndicationFat and cholesterol accumulates on the inside of arteries (atherosclerosis). The small arteries of the heart muscle (the coronary arteries) can be narrowed or blocked by this accumulation. If the narrowing is small, percutaneous transluminal coronary angioplasty, or PTCA for short, may be the course for treatment. PTCA is a minimally invasive procedure to open up blocked coronary arteries, allowing blood to circulate unobstructed to the heart muscle. The indications for PTCA are:Persistent chest pain (angina)Blockage of only one or two coronary arteriesProcedure, part 1While the patient is awake and pain-free (local anesthesia), a catheter is inserted into an artery at the top of the leg (the femoral artery). The procedure begins with the doctor injecting some local anesthesia into the groin area and putting a needle into the femoral artery (the blood vessel that runs from the heart down the leg). Once the needle is inserted, a guide wire is placed through the needle, into the blood vessel. Following this step, the guide wire is left in the blood vessel and the needle is removed. A large needle called an introducer is then placed over the guide wire and the guide wire is removed.Procedure, part 2Next, a diagnostic catheter, which is a long narrow tube, is advanced through the introducer over a .035"guidewire, into the blood vessel. This catheter is then guided to the aorta and the guidewire is removed. Once the catheter is placed in the opening or ostium of one of the coronary arteries, the doctor injects dye and takes a series of X-rays (film of the images).Procedure, part 3The first catheter is exchanged out over the guidewire for a guiding catheter and the guidewire is removed. A smaller guidewire is advanced across the blocked section of the coronary artery and a balloon -tipped tube is positioned so the balloon part of the tube is beside the blockage. The balloon is then inflated for a few seconds to compress the blockage against the artery wall. Then the balloon is deflated. The doctor may repeat this a few times, each time pumping up the balloon a little more to widen the passage for the blood to flow through. This treatment may be repeated at each blocked site in the coronary arteries.Procedure, part 4A device called a stent may be placed. A stent is a latticed, metal scaffold that is placed within the coronary artery to keep the vessel open.Procedure, part 5Once the catheter has been positioned at the coronary artery origin, contrast media is injected and a series of X-rays (film) are taken to check for any change in the arteries. Following this, the catheter is removed and the procedure is completed.Aftercare, part 1This procedure can greatly improve the blood flow through the coronary arteries and to the heart tissue in about 90% of patients and may eliminate the need for coronary artery bypass surgery. The outcome is relief from chest pain symptoms and an improved exercise capacity. In 2 out of 3 cases, the procedure is considered successful with complete elimination of the narrowing or blockage. This procedure treats the condition but does not eliminate the cause and recurrences happen in 1 out of 3 to 5 cases. Patients should consider diet, exercise, and stress reduction measures. If adequate widening of the narrowing is not accomplished, heart surgery (coronary artery bypass graft surgery, also called a CABG) may be recommended.Aftercare, part 2Immediately after the procedure, a ten-pound sandbag may be placed over the femoral artery puncture site in the leg and remain there for 6 hours. This is done to help the artery heal.Reviewed ByReview Date: 05/23/2011Michael A.

How To Manage Coronary Heart Disease?
Coronary Heart Disease is a condition experienced by more than 14 million adults in the United States alone. Although it may seem like a debilitating and destructive diagnosis at first, there are several steps that an affected individual can take to continue living an active and full lifestyle and minimize any long term damages. Coronary Heart Disease is caused by the buildup of plaque in the arteries, which often narrows the artery itself, restricting the flow of blood to the heart. The disease can cause chest pain (also known as angina), or in the event of a completely blocked artery, the occurrence of a heart attack or cardiac arrest. Diet, exercise, education, and cessation of smoking (if applicable) are all aspects of a person’s life which can be examined when Coronary Heart Disease is a risk factor or something that is currently being dealt with. Although there are certain risk factors such as genetics, which cannot be altered, the inclusion of some of the above factors as part of a healthy lifestyle can provide beneficial changes. Diet and exercise are two of the most easily changed areas of a person’s lifestyle. Making a transition from a sedentary lifestyle to an active one can be a slow change, but as long as the progress is steady, the eventual results should prove worthwhile. Diet is also easily altered, thanks to the presence of an array of cookbooks which teach even the most timid cook how to whip up dishes that are both delicious and heart-healthy. Persons who are affected by Coronary Heart Disease would also do well to ask their physician about any specifics of their condition which remain confusing. An informed patient is an empowered patient. When people understand the reasoning behind such lifestyle changes as the ones listed above, the changes they pursue are more likely to remain lifelong instead of short-lived. There are also numerous prescription drugs which help to discourage plaque buildup in the arteries, and are often used in conjunction with the lifestyle alterations that have already been discussed. With the amount of treatment options currently available, Coronary Heart Disease remains a common, yet easily managed condition.
