Seven in ten patients who have suspected angina are not given appropriate testing and are more likely to suffer from serious heart problems as a result, according to a study published on bmj.com today.
Women, older people, patients from ethnic minorities and the poor are the most likely to miss out on testing.
The researchers, led by Professor Gene Feder from the University of Bristol, decided to look into whether patients had equal access to coronary angiography (a specialist x-ray examination in which a contrast agent is injected into the arteries around the heart to show the extent and severity of the narrowing of the arteries around the heart). They wanted to find out if not having an angiography in the early stages of heart disease, when a person presents with suspected stable angina (pains in the chest after exertion), has a long term impact on patients health.
The researchers studied 10,634 patients with suspected stable angina attending six chest pain clinics in England, between January 1996 and December 2002. The sample included white and south Asian patients with chest pain and no known coronary heart disease.
An independent panel of doctors found that 1,375 of these patients needed an angiography. Each patient was followed up three years later to find how and if heart disease had progressed, for example whether they had developed unstable angina, or suffered a heart attack or other heart related problems.
