Researchers Warn Blood Test To Identify Heart Attacks Is Flawed

The blood test used to identify a heart attack or acute myocardial infarction in individuals admitted to the hospital can be deluding, caution researchers. The study was published in The BMJ. In a row, of 20,000 patients undertaking blood tests at the UHS (University Hospital Southampton), it was found that 1 in 20 patients had levels of troponin—a protein discharged in the bloodstream during a heart attack—higher than the producer’s suggested upper limit. But in the majority of these patients, no clinical signs or symptoms of a heart attack were seen. The troponin levels also varied according to many factors like sex, age, and whether inpatient or outpatient.

The researchers—directed by Cardiologist and Professor Nick Curzen—stated these outcomes emphasize necessitate for medical staff to take troponin levels carefully in regard to avert misidentification of a heart attack and wrong treatment. Present guidelines suggest troponin tests to aid exclude or identify a heart attack. Producers of troponin tests give a recommended level (called as the 99th centile) on the basis of values from a few healthy individuals. This advocated level is used as the ULN (upper limit of normal). In simple words, if the value of troponin is more than the 99th percentile, that is believed to be abnormal and will indicate a heart attack in the right clinical circumstances.

On a similar note, recently, a study showed that high testosterone levels can play a function in severe heart conditions. Having a genetic inclination to high testosterone levels can lead to the development of major cardiac problems in men, like heart failure and blood clots. This study was published in The BMJ. The findings might also have propositions for men who intake testosterone supplements to improve energy levels and sex drive.
