QUT researchers have found a way to identify the risk of stroke for indigenous patients, which could speed up treatment follow-up and ease hospital congestion.

The results of a single trial can be used to validate heart failure in up to one-third of Aboriginal and Torres Strait Islander patients with low levels of troponin according to the QUT study.

Published today in Australian Medical JournalQUT Assistant Professor Jaimi Greenslade from the Australian Institute of Public Health (AusHSI) evaluated data from 110 patients presented. chest pain to the emergency department of Cairn Hospital.

Professor Greenslade says the current system for diagnosing heart disease is to test for levels of troponin, a protein that emanates from damaged heart muscle. blood flowduring the patient’s appearance again 2-3 hours later.

“There is a wealth of evidence to suggest that a single trial may be sufficient to rule out coronary heart disease in a group of non-indigenous patients, but a brief study evaluates the use of a single trial for indigenous patients,” says Professor Greenslade. who is also an Advance Queensland Fellow at Royal Brisbane and Women’s Hospital.

“Our research provides first evidence that the use of a single trial may be as safe for primary care patients as for non-primary care patients.

“We found that of the patients with low levels of troponin on presentation, none ended up with a heart attack within 30 days.”

Professor Greenslade says the root cause of the risk of coronary heart disease is greater for primary care patients than primary care patients, so researchers need to make sure that the methods used to eliminate coronary heart disease are not safe for this. association.

“The traditional method used to diagnose heart failure has been very long and there are a large number of patients presenting to the emergency department with chest pain each year, contributing to congestion.

“A lot of research has looked at whether there is a way to speed up this process. One of the findings is that patients with low results in the first blood test are less likely to have a heart attack and may not need a second test. or additional testing.

“It is unknown at this time what he will do after leaving the post.

“What is happening is that the indigenous patients’ union may also be discharged early and may not require a long hospital stay.”

The study also reported that the majority of participants reported dangers because cardiovascular disease-66% smokers, 40% have diabetes, 56% have high blood pressure, and 57% have a history of coronary heart disease.

“Low levels of troponin can be safely isolated heart attackbut Aboriginal and Torres Strait Islander could benefit from the delivery of traditional health care services to manage the risk of heart disease, ”said Professor Greenslade.

Professor Greenslade said the observed observations are small, and more research is needed on large groups in many places to find out if the study can be supported if it is implemented in clinical practice.
