Although angina does not permanently damage the heart. The difference between a heart attack and angina is that a heart attack could cause permanent damage to the heart muscle. Angina symptoms are the feeling of pressure or tightness in the middle of the chest; this pressure may spread to the left side of the body – the arm, shoulder or hand and it may even affect the jaw, neck and throat and an angina attack usually lasts for a few short minutes.

There are 2 types of angina: stable and unstable.

Stable angina is from a permanent or fixed obstruction of blood flow to the heart. This happens when the blood supply is not enough to keep up with a heart that’s pumping fast and when the heart slows down sufficient blood goes through and this indicates that the patient is at a state of rest. There are blockages in the heart but it’s not bad enough to stop the flow of blood and this does not damage the heart unless an atheroma, or fatty deposit, ruptures.

Unstable angina is an interruption of the blood flow to the heart due to a complete blockage. This normally occurs when the person is at rest or is doing some physical activity or exertion. The development of unstable angina may develop quickly and attacks are frequent and/or increase in intensity. Unstable angina is more serious than a stable angina. While stable angina does not lead to a heart attack however an unstable angina – which could wake a person from sleep – this could lead or progress into a heart attack in fact, some physicians consider an unstable angina attack as a heart unless tests show otherwise.

An unstable angina the plaque in the coronary artery may rupture – called plaque fissuring. This then dissolved the tissue separating the plaque from the blood flow. Once the blood has contact with the plaque it will then develop a clot around the plaque. The clot will get bigger and may cause the pain, angina, or it may develop into a heart attack this is depending on how much blockage is on the artery. Sometimes, the clot may travel to a different part of the artery and blocks the artery which then leads to a heart attack. And even yet, sometimes the clot is washed away when the ruptured artery or plaque will heal. Further, a stable narrowing of the coronary artery may become unstable and then it reduced the blood flow through the coronary artery disease that is affected and thus causing the symptoms even while at a rest state.

People who experience angina gets so alarmed, and rightfully so, as they believe they are having a heart attack plus, the feeling is not usual (for first time experience). A stable angina is NOT a heart attack and people with stable angina respond well to drug treatment. Even though it is not a heart attack, this should not be taken lightly. There are treatments and therapy available and people with angina may continue to live a good life with minimal change in lifestyle besides diet, exercise and no smoking.

But stable angina is NOT a heart attack. In fact, most people with stable angina respond well to modern treatments and live full lives for many years – if they follow their physician’s advice, take medication as prescribed, and learn to look after their hearts.

Although angina therapy is better than ever before, successful treatment depends upon close cooperation between the individual and the healthcare team. The person with angina must assume a lifestyle that minimizes the risk of further heart trouble.
