According to reports, the new £20 blood test method can double the detection rate of female heart disease.

Doctors believe this will save the lives of women who have previously missed myocardial cell damage.

The current test method can detect the heart problem of male patients with chest pain, the diagnosis rate is 19%, while the female detection rate is only 11%.

The new detection method is more sensitive and can increase the detection rate of both sexes to about 22%. Heart disease patients who are undiagnosed are more likely to progress due to lack of proper treatment and have a potentially fatal episode. A troponin assay developed by American company Abbott can diagnose heart disease, and troponin is released into the blood by damaged cells. The new method is more sensitive to detect female heart disease because doctors reduce the female positive detection threshold. Anoop Shah, a cardiologist at the University of Edinburgh who studies the method, said: "The number of men and women who go to the emergency department due to chest pain is similar. We want to know why women have a lower rate of heart disease than men. Our study shows that men and women have heart disease. One of the reasons for the difference in detection rates is because the current troponin threshold is too high for women. Once different thresholds are used for men and women, the diagnosis of heart disease will be more accurate and the patient's outcome will be improved. We are using The British Heart Association provides funding for large-scale clinical trials of the method."

Dr. Shah used this method to get a 22% diagnosis of heart disease, the same as men and women. The rationale for the new method is based on the lower risk of troponin risk in women than in men. The researchers said that the diagnosis of female heart disease was doubled by using different troponin levels for men and women.

The high-sensitivity test method was supported by NIH and CE last year, which is the first example of the value of gender-specific testing.

The new method is the same price as the standard method and is £20. The diagnosis of heart disease is usually based on symptoms supported by blood tests. Patients with chest pain are generally given an electrocardiogram and blood test to assess myocardial damage.

Troponin is present in the heart cell and is released into the blood when the heart is damaged by cardiac ischemia. Anjiu University of Edinburgh, is published in the British medical journal.
