TREATMENT
Medical Treatment
Medical treatment may be started immediately, before a definite diagnosis of a heart problem is made.Oxygen through a tube in the nose or face mask,nitroglycerin under the tongue, pain medicines (morphine or meperidine)and aspirin all include general treatment.Also,those with allergy to aspirin may be given clopidogrel (Plavix).

Stenting: A stent is a small, springlike device that may be inserted into a coronary artery after balloon angioplasty. After the catheter and balloon are removed, the stent stays in place, holding the artery open. A stent is better than angioplasty alone at keeping the artery from narrowing again.
Atherectomy: Sometimes the plaques are too rigid, bulky, or calcified to be treated by balloon angioplasty. In these cases, the plaque often can be removed by cutting it out with a drill-like rotary blade or a laser or other tool.
Medications
Intravenous (IV) nitroglycerin has been shown to improve blood flow to the heart muscle by relaxing (dilating) the coronary arteries and increasing blood flow. It is usually given for 24-48 hours continuously.Beta-blockers are medications that decrease the heart rate and blood pressure. This reduces the heart's workload and thus the amount of oxygen it needs. Beta-blockers may provide immediate as well as long-term benefit for people who have a heart attack.Angiotensin-converting enzyme (ACE) inhibitors may prevent repeat heart attacks and other problems when started early during a heart attack. They are especially useful in people with diabetes and those with a weakened heart muscle congestive heart failure).

Surgery
Standard coronary artery bypass grafting (CABG) is performed if many coronary arteries are narrowed or blocked. This is especially recommended when the left main coronary artery shows significant blockage. This is "open heart surgery," meaning that the chest wall is opened. When performing a bypass, heart surgeons use sections of the mammary artery from the chest or veins from the legs to create detours around the blocked arteries. For this surgery, you will be connected to a bypass pump, which does the work of the heart during the operation. Although this sounds dangerous, this surgery is considered very safe and has a very low rate of complications.Off-pump bypass surgery: Sometimes the surgeon can perform open heart surgery without using a bypass pump. The heart continues to beat during surgery. This type of surgery has even fewer complications than the standard procedure but is not always feasible.

PREVENTION
1. Don't smoke or use tobacco products
Smoking or using other tobacco products is one of the most significant risk factors for developing heart disease. When it comes to heart disease prevention, no amount of smoking is safe. Smoke less tobacco and low-tar and low-nicotine cigarettes are also risky, as is exposure to secondhand smoke.Tobacco smoke contains more than 4,800 chemicals. Many of these can damage your heart and blood vessels, making them more vulnerable to narrowing of the arteries (atherosclerosis). Atherosclerosis can ultimately lead to a heart attack.

In addition, the nicotine in cigarette smoke makes your heart work harder by narrowing your blood vessels and increasing your heart rate and blood pressure. Carbon monoxide in cigarette smoke replaces some of the oxygen in your blood. This increases your blood pressure by forcing your heart to work harder to supply enough oxygen. The good news, though, is that when you quit smoking, your risk of heart disease drops dramatically within just one year. And no matter how long or how much you smoked, you'll start reaping rewards as soon as you quit.

Most people, for instance, need to add more fruits and vegetables to their diet — with a goal of five to 10 servings a day. Eating that many fruits and vegetables can not only help prevent heart disease but also may help prevent cancer. Omega-3 fatty acids, a type of polyunsaturated fat, may decrease your risk of heart attack, protect against irregular heartbeats and lower blood pressure. Some fish are a good natural source of omega-3s. However, pregnant women and women of childbearing age should avoid shark, swordfish, king mackerel and tilefish because they contain levels of mercury high enough to pose a danger to a developing fetus.

2. Eat a heart-healthy diet
Eating a special diet called the Dietary Approaches to Stop Hypertension (DASH) eating plan can also help protect your heart. Following the DASH diet means eating foods that are low in fat, cholesterol and salt. The diet is rich in fruits, vegetables, whole grains and low-fat dairy products that can help protect your heart. Legumes, low-fat sources of protein and certain types of fish also can reduce your risk of heart disease.Limiting certain fats you eat is also important. Saturated fat and trans fats increase the risk of coronary artery disease by raising blood cholesterol levels. Major sources of saturated fat include beef, butter, cheese, milk, and coconut and palm oils. There's growing evidence that trans fats may be worse than saturated fat because unlike saturated fat, it both raises your low-density lipoprotein (LDL), or "bad," cholesterol, and lowers your high-density lipoprotein (HDL), or "good," cholesterol. Sources of trans fats include some deep-fried fast foods, bakery products, packaged snack foods, margarines and crackers. Heart-healthy eating isn't all about cutting back, though.

3. Get regular health screenings
High blood pressure and high cholesterol can damage your heart and blood vessels. But without testing for them, you probably won't know whether you have these conditions. Regular screening can tell you what your numbers are and whether you need to take action.
