Mayo Clinic study confirms smoke-free workplaces reduce heart attacks

15.11.2011
Mayo Clinic researchers have amassed additional evidence that secondhand smoke kills and smoke-free workplace laws save lives. The study will be presented to the American Heart Association's Scientific Sessions on Monday in Orlando.

Their research shows that the incidence of heart attacks and sudden cardiac deaths was cut in half among Olmsted County, Minn., residents after a smoke-free ordinance took effect. Adult smoking dropped 23 percent during the same time frame, as the rates of other risk factors such as high blood pressure, high cholesterol, diabetes and obesity remained stable or increased.

"This study adds to the observation that smoke-free workplace laws help reduce the chances of having a heart attack, but for the first time we report these laws also reduce the chances of sudden cardiac death," says Richard Hurt, M.D., director of Mayo Clinic's Nicotine Dependence Center. "The study shows that everyone, especially people with known coronary artery disease, should avoid contact with secondhand smoke. They should have no -- literally no -- exposure to secondhand smoke because it is too dangerous to their health."

Dr. Hurt played an instrumental role in the passage of smoke-free ordinances in Olmsted County and the state of Minnesota. He says evidence from this new study will strengthen efforts by the Global Smoke-Free Worksite Challenge, a recently formed tobacco control advocacy collaboration that debuted at a Clinton Global Initiative event. The Challenge will encourage other countries and employers to expand the number of employees able to work in smoke-free environments.

"We are going to use this information to help us convince corporations -- convince countries -- that this is the right thing to do to protect the health of their workers and their citizens," Dr. Hurt says.

The study draws data from the Rochester Epidemiology Project, a long-term, collaborative medical records project among health care providers in Olmsted County. The project makes Mayo Clinic one of the few places in the world where retrospective population-based studies are possible and allows researchers at Mayo Clinic to zero in on the frequency of certain conditions.

"This study underscores once more the importance of monitoring heart disease in communities in order to understand how to enhance cardiovascular health," says Véronique Roger, M.D., director of Mayo Clinic's Center for the Science of Health Care Delivery, who leads cardiovascular disease surveillance through the Rochester Epidemiology Project.

The population-based study showed that during the 18 months before Olmsted County's first smoke-free law for restaurants was passed in 2002, the regional incidence of heart attack was 212.3 cases per 100,000 residents. In the 18 months following a comprehensive smoke-free ordinance in 2007, in which restaurants and workplaces became smoke-free, that rate dropped to 102.9 per 100,000 residents -- a decrease of about 45 percent. Additionally, during these two time periods, the incidence of sudden cardiac death fell from 152.5 to 76.6 per 100,000 residents -- a 50 percent reduction.

"Our findings provide support to the life-saving effect that smoke-free legislation can have among community members affected by these laws," said co-author Jon Ebbert, M.D., associate director of Mayo Clinic's Nicotine Dependence Center

Other Mayo study authors are Ivana Croghan, Ph.D., Darrell Schroeder, Susan Weston and Sheila M. McNallan.

The study was supported by a grant from ClearWay Minnesota, an independent, nonprofit organization that improves the health of all Minnesotans by reducing tobacco use and exposure to secondhand smoke through research, action and collaboration.

Global Smoke-Free Worksite Challenge is a collaboration among the American Cancer Society, the Global Business Coalition on Health, Johnson & Johnson, Mayo Clinic, the Campaign for Tobacco-Free Kids and the U.S. Department of Health & Human Services.

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
