What to look for:
* pain that is crushing, constricting, strangling, suffocating, sharp, or burning… It is normally felt in the chest but may also occur in other areas such as the jaw or abdomen. Location and specific sensations vary from person to person but are usually consistent from one attack to the next.
* pain that occurs with exertion or excitement and recedes with rest.
* pain usually only lasts for a few minutes
* weakness, sweating, shortness of breath, anxiety, palpitations, nausea, or light-headedness… Symptoms that may or may not be associated with an angina attack.
* patients who have had angina attacks may go on to have full blown heart attacks and vice versa
Of the many types of angina, stable, or classical, angina, triggered by exertion and receding with rest is the most common.
If you have stable angina, you should be able to predict what sort of activity will bring on an attack. Another type, unstable angina, is a more acute condition; it occurs unpredictably, even during rest, and should be interpreted as a warning sign of more serious heart trouble.
Alone, angina causes no permanent damage because the heart is only temporarily deprived of oxygen. But if your angina worsens, you should know that you are at a greater risk of heart attack. Be especially concerned if you develop unstable angina, and consult a doctor.
Causes
The main underlying cause of angina is coronary artery disease which describes the disease which the arteries become blocked by fatty deposits and blood is prevented from flowing through them. Angina can also result from other diseases that put exertion upon the heart unnecessarily, such as anaemia, aortic valve disease (see heart disease), heart arrhythmias, and hyperthyroidism (see thyroid problems).
Stable angina is sometimes called 'exertional' angina because it is triggered by activities that make the heart beat rapidly such as physical activity, such as heavy lifting, sexual activity to eating a large meal.
Other triggers are emotional excitement cold weather, both of which stimulate the heart.
Certain risk factors for heart disease and coronary artery disease make the development of angina more likely.
These include:
* high blood pressure,
* stress,
* high cholesterol
* smoking,
* obesity,
* diabetes,
* and a family history of heart disease.
Treatments
Drugs may alleviate angina symptoms, but fundamental changes in diet and lifestyle are an important part of any angina treatment program. Before taking any drug, review its properties and your medical history carefully with your Doctor and Pharmacist.
Many drugs should not be mixed with other drugs or natural medicines, and you also need to be sure your Doctor knows of any pre-existing medical conditions you may have.
If you have angina, your doctor will undoubtedly mention the importance of an overall healthy lifestyle that includes proper diet, exercise, weight management, and no smoking.
Most angina patients also take prescribed medication. There are three main classes of angina drugs…
Nitrates,
Beta-adrenergic blockers and
Calcium channel blockers.
Physicians often use a combination of these to treat angina.
If drug therapy does not work Angioplasty or bypass surgery may be considered. Angioplasty, a catheter technique that widens blocked arteries, has become a relatively routine procedure. Bypass surgery, which diverts blood flow around clogged arteries, is reserved for very severe cases.
