Sweat is good indicator heart attack may be coming


Sweating during physical activity or in hot weather is healthy. But when individuals begin perspiring while experiencing discomfort in their chest, arm, neck or jaw -- with little or no exertion -- it could be the onset of a heart attack, according to a new study at the University of Illinois at Chicago.

"We can stop a heart attack during the process, but you have to get to the hospital first," said Catherine Ryan, research assistant professor of medical surgical nursing. "The real push for improved survival is to get them there early."

Ryan presented her findings at the American Heart Association’s annual meeting this week in Dallas.

Time is of the essence during a heart attack, and doctors have urged people who experience common symptoms -- shortness of breath, cold sweats, nausea, lightheadedness, or discomfort in the chest, arm, neck or jaw -- to get to a hospital as quickly as possible. But delay in seeking treatment is common, and worsens the outcome after a heart attack, Ryan said.

Ryan sought to determine whether delay was related to the symptom cluster individuals experienced during a heart attack. Earlier studies about the delay, she said, focused on only one symptom, not clusters, or on demographic characteristics of the patients.

She asked the authors of 10 such studies to send her their data, and eight groups of authors in the United States and Great Britain complied. The data had been collected in interviews with 1,073 patients who had had heart attacks.

Ryan studied 12 common symptoms: chest discomfort; shoulder, arm, or hand discomfort; neck or jaw discomfort; back discomfort; abdominal discomfort; indigestion; nausea and vomiting; shortness of breath; sweating; dizziness and light-headedness; weakness; and fatigue.

Her analysis showed that individuals with the shortest delays (a mean of 9.78 hours) had a greater probability of experiencing the largest number of symptoms. Individuals with the longest delays (a mean of 22.77 hours) had moderate probability of experiencing chest pain and shortness of breath.

Sweating may be a key variable in the symptom cluster prompting individuals to seek treatment, Ryan said. But the research could not determine whether sweating is an indication of a more serious heart attack.

The study was funded by the National Institutes of Health through UIC’s Center for Reducing Risks in Vulnerable Populations.

Im Focus: Researchers Discover New Anti-Cancer Protein

An international team of researchers has discovered a new anti-cancer protein. The protein, called LHPP, prevents the uncontrolled proliferation of cancer cells in the liver. The researchers led by Prof. Michael N. Hall from the Biozentrum, University of Basel, report in “Nature” that LHPP can also serve as a biomarker for the diagnosis and prognosis of liver cancer.

The incidence of liver cancer, also known as hepatocellular carcinoma, is steadily increasing. In the last twenty years, the number of cases has almost doubled...

Im Focus: Researchers at Fraunhofer monitor re-entry of Chinese space station Tiangong-1

In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.

Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...

Im Focus: Tiny implants for cells are functional in vivo

For the first time, an interdisciplinary team from the University of Basel has succeeded in integrating artificial organelles into the cells of live zebrafish embryos. This innovative approach using artificial organelles as cellular implants offers new potential in treating a range of diseases, as the authors report in an article published in Nature Communications.

In the cells of higher organisms, organelles such as the nucleus or mitochondria perform a range of complex functions necessary for life. In the networks of...
