Angina pectoris, examinations and tests

New onset angina pectoris

In most people with angina, the condition is stable, it worsens small and they can live with their angina for many years without causing complications. However, angina pectoris is also a condition that can have serious consequences, because angina may be a precursor to heart attacks , heart arrhythmias and cardiac arrest.

Diagnosis can in most cases be set with great accuracy by the GP on the basis of a typical history. Exploration of the body, blood tests and ECG can help the GP to determine whether there is damage to the heart, and to identify possible risk factors for heart disease. Blood specimens for examination of diabetes and measurement of the cholesterol content in the blood included in this study.

To clarify the severity of angina pectoris, it will often be necessary to refer you to a cardiologist for possible further investigation. In the first place it is necessary to get all the exercise ECG and possibly get done ultrasound examination of the heart ( echocardiography ). Abnormal findings may necessitate further evaluation and possible treatment - primarily in the form of cardiac catheterization .

ECG and exercise ECG
ECG is a harmless and painless examination done on anyone suspected of having heart disease. The survey records the electrical signals of the heart. Under normal conditions, recording an ECG shows a typical pattern. Deviations from this pattern may reflect illness or injury in the heart. In addition, the ECG information about heart rate and the heart is overloaded (enlarged). Most primary care practices are equipped with ECG.

By angina , an ordinary ECG generally be normal at rest, ie without anginal pain. Conversely, recording an ECG could show typical changes if it finds while you exert yourself (exercise ECG). Such a survey does not capture all. The strong suspicion of angina but normal exercise ECG, will still be referred to cardiac catheterization. Exercise ECG performed by cardiologists and internists both outside and in the hospital.

An abnormal exercise ECG can provide information on how severe the condition is angina, and information useful for the further study.

Ultrasound of the heart may be a necessary investigation to determine whether there is underlying disease of the heart or if there is damage to the heart after previous myocardial infarction. Some heart attacks are in fact "dumb", they can proceed entirely without symptoms.

Study in hospital
If you are placed or referred for assessment in hospital in connection with a powerful angina attacks, it will usually be taken a number of other studies as well.

X-ray of the chest
A røngenbilde of the lungs and heart shows the size of the heart is as expected and whether there is any liquid or other changes in the lungs. Tight blood vessels or damage caused by previous heart attack is not visible on plain radiographs. X-ray examination is also important to rule out other explanations for breast your pain.

Blood tests
There is no blood test that can reveal angina pectoris with certainty, but blood tests used to diagnose or rule out heart attack.

This study is not available at all hospitals. The study may be relevant in uncertain findings load ECG. Scintigraphy of the heart is a bloodless isotope studies of the heart (the use of a tiny dose radioactive substance). The study carried out with the use of computer technology that makes it possible to make cut images of the heart (computed tomography).

This is the most accurate examination of the heart muscle blood vessels (arteries or coronary arteries in technical language). The study implies that a thin plastic catheter inserted into the artery in the groin or wrist, entered into the heart and into the coronary arteries. Contrast material is injected into the coronary arteries while taking pictures. Doctors will then be able to detect and locate any narrowing of years. If narrowing treatable by blocking the years, made it in the same session.
