Sweat is good indicator heart attack may be coming

23.11.2005


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: New interactive machine learning tool makes car designs more aerodynamic

Scientists develop first tool to use machine learning methods to compute flow around interactively designable 3D objects. Tool will be presented at this year’s prestigious SIGGRAPH conference.

When engineers or designers want to test the aerodynamic properties of the newly designed shape of a car, airplane, or other object, they would normally model...

Im Focus: Robots as 'pump attendants': TU Graz develops robot-controlled rapid charging system for e-vehicles

Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.

Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....

Im Focus: The “TRiC” to folding actin

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.

Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...

Im Focus: Lining up surprising behaviors of superconductor with one of the world's strongest magnets

Scientists have discovered that the electrical resistance of a copper-oxide compound depends on the magnetic field in a very unusual way -- a finding that could help direct the search for materials that can perfectly conduct electricity at room temperatur

What happens when really powerful magnets--capable of producing magnetic fields nearly two million times stronger than Earth's--are applied to materials that...

Im Focus: World record: Fastest 3-D tomographic images at BESSY II

The quality of materials often depends on the manufacturing process. In casting and welding, for example, the rate at which melts solidify and the resulting microstructure of the alloy is important. With metallic foams as well, it depends on exactly how the foaming process takes place. To understand these processes fully requires fast sensing capability. The fastest 3D tomographic images to date have now been achieved at the BESSY II X-ray source operated by the Helmholtz-Zentrum Berlin.

Dr. Francisco Garcia-Moreno and his team have designed a turntable that rotates ultra-stably about its axis at a constant rotational speed. This really depends...
