Angina pectoris is the result of myocardial ischemia caused by an imbalance between myocardial blood flow and oxygen demand. In most cases is the lack of blood flow due to a narrowing of the coronary arteries due to atherosclerosis. This pain is known as angina. It is more likely to occur during exercise (walking, climbing stairs) when the heart muscle needs more blood and oxygen if it works harder. Angina usually occurs during exercise, severe emotional stress, or after a heavy meal. During these periods requires the heart muscle oxygen more blood than the narrowed coronary arteries can deliver.
Angina pectoris is common. It affects about 1 in 50 people and there are an estimated 1.2 million people with angina pectoris in the United Kingdom. It is more common in men than women, and the probability of occurrence increases with age. Angina pectoris can also occur in people with vasoconstriction cardiovascular disease, Hypertrophic cardiomyopathy (this is an enlarged heart due to illness) or uncontrolled high blood pressure. Typical angina is uncomfortable pressure, fullness, squeezing or pain in the center of the chest. Many types of chest discomfort not related to angina. Acid reflux (heartburn) and lung infection or inflammation are examples.
Causes of Angina
The common causes of Angina:
Heart Failure
Narrowing of the aortic heart valve
Anaemia,
Abnormal heart rhythms
Fast, abnormal heart rhythms,
Diseases of the heart muscle.
Coronary spasm (also known as Prinzmetal's angina)
Symptoms of Angina
Some symptoms of Angina:
Shortness Of Breath
Nausea
Sense of moderate to severe persistent indigestion
Transpiration
Sharp, fires or cramp pain
Numbness or loss of sensation in your arms, shoulders or wrists.
Can also occur in the arms, shoulders, neck, jaw, throat or back
Usually start in the chest behind the breastbone
Treatment of Angina
Eliminate or minimize risk factors for coronary heart diseases by treatment of high blood pressure, high cholesterol lowering, stop smoking, exercise and weight loss, if necessary.
Treatment with medications such as beta-blockers, nitrates (such as nitroglycerin), calcium channel blockers, angiotensin-converting enzyme (ACE) inhibitors and anti-clotting drug
Rest.
Angiography can be performed if the symptoms do not improve to help determine whether coronary bypass surgery or angioplasty is needed
Transmyocardial laser revascularization (TMR) is a new technique to relieve severe angina or coronary disease in patients unable to bypass surgery or angioplasty.
Lowering LDL cholesterol levels as much as possible use of drugs.
Hospitalization if symptoms get worse fast.
