Coronary artery disease develops when your coronary arteries — the major blood vessels that supply your heart with blood, oxygen and nutrients — become damaged or diseased. Cholesterol-containing deposits (plaque) on your arteries are usually to blame for coronary artery disease. Omega-3 fatty acids are a type of unsaturated fatty acid that’s thought to reduce inflammation throughout the body, a contributing factor to coronary artery disease. Fish and fish oil are the most effective sources of omega-3 fatty acids. Fatty fish, such as salmon, herring and to a lesser extent tuna, contain the most omega-3 fatty acids and therefore the most benefit. Fish oil supplements may offer benefit, but the evidence is strongest for eating fish. Flax and flaxseed oil also contain beneficial omega-3 fatty acids, though studies have not found these sources to be as effective as fish. The shell on raw flaxseeds also contains soluble fiber, which can help lower blood cholesterol. Other dietary sources of omega-3 fatty acids include walnuts, canola oil, soybeans and soybean oil. These foods contain smaller amounts of omega-3 fatty acids than do fish and fish oil, and evidence for their benefit to heart health isn’t as strong.
Your doctor may recommend coronary angioplasty if you have narrow or blocked coronary arteries as a result of coronary heart disease (CHD).
Angioplasty is one treatment for CHD. Other treatments include medicines and coronary artery bypass grafting (CABG). CABG is a type of surgery in which a healthy artery or vein from the body is connected, or grafted, to a blocked coronary artery.
The grafted artery or vein bypasses (that is, goes around) the blocked portion of the coronary artery. This improves blood flow to the heart.
Compared with CABG, some advantages of angioplasty are that it: -Doesn’t require open-heart surgery -Doesn’t require general anesthesia (that is, you won’t be given medicine to make you sleep during the procedure) -Has a shorter recovery time
However, angioplasty isn’t for everyone. For some people, CABG might be a better option. For example, CABG might be used to treat people who have severe CHD, narrowing of the left main coronary artery, or poor function in the lower left heart chamber.
Your doctor will consider many factors when deciding which treatment(s) to recommend. Angioplasty also is used as an emergency treatment for heart attack. As plaque builds up in the coronary arteries, it can rupture. This can cause a blood clot to form on the surface of the plaque and block blood flow to the heart muscle. Quickly opening the blockage restores blood flow and reduces heart muscle damage during a heart attack.
Statins are a class of medicines that are frequently used to lower blood cholesterol levels. The drugs are able to block the action of a chemical in the liver that is necessary for making cholesterol.
Although cholesterol is necessary for normal cell and body function, very high levels of it can lead to atherosclerosis, a condition where cholesterol-containing plaques build up in arteries and block blood flow. By reducing blood cholesterol levels, statins lower the risk of chest pain (angina), heart attack, and stroke. Several types of statins exist such as atorvastatin, cerivastatin, fluvastatin, lovastatin, mevastatin, pitavastatin, pravastatin, rosuvastatin, and simvastatin. Atorvastatin and rosuvastatin are the most potent, while fluvastatin is the least potent. These medicines are sold under several different brand names including Lipitor (an atorvastatin), Pravachol (a pravastatin), Crestor (a rosuvastatin), Zocor (a simvastatin), Lescol (a fluvastatin) and Vytorin (a combination of simvastatin and ezetimibe). Mevastatin is a naturally occurring statin that is found in red yeast rice.
Angina is relatively common but can be hard to distinguish from other types of chest pain, such as the pain or discomfort of indigestion. If you have unexplained chest pain, seek medical attention right away.
Angina is a type of chest pain caused by reduced blood flow to the heart muscle. Angina is a symptom of coronary artery disease. Angina is typically described as squeezing, pressure, heaviness, tightness or pain in your chest.
Angina, also called angina pectoris, can be a recurring problem or a sudden, acute health concern.
To diagnose angina, your doctor will start by doing a physical exam and perhaps the most accurate would be the Nuclear Stress Test. Watch video:
