Heart Attack Patients Get Safer, Faster Lab Scores That Diagnose Diseases

Within one month of the emergency department visits, 727 heart attacks or deaths in patients occurred.

Researchers have developed a simple laboratory score which is safer and faster at diagnosing patients who visit the emergency department with heart attack symptoms.

The findings, published in the CMAJ (Canadian Medical Association Journal), suggest that the score can also identify patients at risk of subsequent heart issues after discharge.

“We have developed a simple lab score that is superior to using cardiac troponin alone for the identification of patients at low and high risk for heart attack or death at emergency department presentation,” said co-author Peter Kavsak from the McMaster University in Ontario, Canada.

“This lab score may reduce both the number of blood tests and the time spent in the emergency department for chest pain patients,” Andrew Worster, Professor at the varsity, said.

For the study, the team combined common laboratory blood tests available at several hospitals around the world to create a single laboratory score or clinical chemistry score, to diagnose a heart attack.

These blood tests are part of the World Health Organization’s (WHO) list of essential in vitro diagnostic tests for health care facilities with clinical laboratories.

The researchers validated the clinical chemistry score as a predictor of heart attacks or deaths within 30 days, using the data on 4,245 patients from emergency department studies in four countries — Canada, Australia, New Zealand, and Germany.

Within one month of the emergency department visits, 727 heart attacks or deaths in patients occurred.

A negative (or low-risk) clinical chemistry score at emergency department presentation missed only one of these events compared with up to 25 missed heart attacks or deaths when using a high-sensitivity cardiac troponin test alone.

A positive (or high-risk) clinical chemistry score also identified about 75 per cent of the patients at high risk of heart attacks or deaths when positive compared with a low of 40 per cent detected when the high-sensitivity cardiac troponin test alone was positive.

The researchers suggest the score can be useful for standardising diagnoses and improving safety. (IANS)

Paralysis Causing Illness In Children Baffles Doctors

Parents are urged to have their children take basic precautions, such as washing hands and using insect spray to ward off mosquito bites.

Federal and state health officials are baffled by a mysterious and rare illness that seems to target children, causing paralysis.

As of Tuesday, 62 cases of what doctors are calling acute flaccid myelitis have been confirmed in 22 states. Sixty-five suspected cases are being investigated.

“There is a lot we don’t know about AFM and I am frustrated that despite all of our efforts, we haven’t been able to identify the cause of this mystery illness,” Nancy Messonnier, a top official at the Centers for Disease Control, said Tuesday.

What is known about the illness is that more than 90 percent of the confirmed cases are in children 18 years old or younger. The average age of patients is 4.

Victims generally suffer from muscle weakness and some paralysis of the face, neck, back, arms and legs. The paralysis sets in about a week after the children have come down with fever and respiratory illness.

There is no specific treatment, and most of the victims recover. But the long-term effects are still unknown.

Messonnier called it a “pretty dramatic disease.”

Health experts have ruled out some causes, including poliovirus and West Nile virus.

But what is particularly confounding doctors is that the number of cases spikes only every other year — with larger numbers in 2014, 2016 and this year — and fewer cases in 2015 and 2017.

Any child experiencing weakness or loss of muscle tone in the arms and legs should be examined immediately. (VOA)
