Physical fitness improves survival, prevents some heart attacks

18.11.2013
A new study highlights the importance of exercise and physical fitness among people with stable coronary artery disease.

Researchers at the Johns Hopkins University School of Medicine and Henry Ford Hospital found that higher levels of physical fitness lower the risk of having heart attacks and increase survival in those with coronary artery disease, whether or not they have had a procedure to open up their blocked arteries.

"In our study, the patients who were most fit had a 75 percent lower risk of dying from any cause compared to those who were least fit. This was true regardless of whether the patient had previous stenting or bypass surgery to open up any blocked arteries," says lead author Rupert Hung, a medical student at the Johns Hopkins University School of Medicine.

Hung presented the findings in a poster presentation titled "The Prognostic Value of Exercise Capacity in Patients with Non-Revascularized and Revascularized Coronary Artery Disease: The FIT Project," on November 17, 2013, at the American Heart Association's Scientific Sessions in Dallas, Texas.

The study included information on more than 9,800 adults who had been diagnosed with coronary artery disease. All of the patients in the study had been referred by a physician to undergo a treadmill stress test and were followed for an average of 11 years to see whether they had a heart attack, had undergone a revascularization procedure to restore blood flow, or had died from any cause.

"We measured exercise capacity, expressed as metabolic equivalents, or METS, from the patients' stress test results. We found that each 1-MET increase in a person's exercise capacity was associated with a 13 percent reduction in risk of death, regardless of whether they had previously had a procedure to open a blocked artery," says co-investigator John W. McEvoy, M.B., B.Ch., a cardiology fellow at the Johns Hopkins University School of Medicine.

The researchers say their findings highlight the importance of physical activity and fitness among people with coronary artery disease.

"Improving and maintaining fitness should be a high priority for patients," says senior author Michael Blaha, M.D., M.P.H., an assistant professor of medicine at the Johns Hopkins University School of Medicine and a cardiologist with the Johns Hopkins Ciccarone Center for the Prevention of Heart Disease.

"Our results suggest that increasing physical fitness through cardiac rehabilitation programs and exercise may be an effective supplement to medications for preventing complications associated with coronary artery disease. We hope that as a result of this study, more physicians will consider prescribing physical activity as a front-line therapy to improve survival and quality of life for their patients who are able to safely exercise," says Blaha.

Johns Hopkins Medicine (JHM), headquartered in Baltimore, Maryland, is a $6.7 billion integrated global health enterprise and one of the leading academic health care systems in the United States. JHM unites physicians and scientists of the Johns Hopkins University School of Medicine with the organizations, health professionals and facilities of The Johns Hopkins Hospital and Health System. JHM's vision, "Together, we will deliver the promise of medicine," is supported by its mission to improve the health of the community and the world by setting the standard of excellence in medical education, research and clinical care. Diverse and inclusive, JHM educates medical students, scientists, health care professionals and the public; conducts biomedical research; and provides patient-centered medicine to prevent, diagnose and treat human illness. JHM operates six academic and community hospitals, four suburban health care and surgery centers, and more than 35 Johns Hopkins Community Physicians sites. The Johns Hopkins Hospital, opened in 1889, was ranked number one in the nation for 21 years in a row by U.S. News & World Report.

Im Focus: Future electronic components to be printed like newspapers

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.

The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...

Im Focus: First evidence on the source of extragalactic particles

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.

To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...

Im Focus: Magnetic vortices: Two independent magnetic skyrmion phases discovered in a single material

For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...

Im Focus: Breaking the bond: To take part or not?

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.

A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...

Im Focus: New 2D Spectroscopy Methods

Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.

"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
