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: The working of a molecular string phone

Researchers from the Department of Atomically Resolved Dynamics of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg, the University of Potsdam (both in Germany) and the University of Toronto (Canada) have pieced together a detailed time-lapse movie revealing all the major steps during the catalytic cycle of an enzyme. Surprisingly, the communication between the protein units is accomplished via a water-network akin to a string telephone. This communication is aligned with a ‘breathing’ motion, that is the expansion and contraction of the protein.

This time-lapse sequence of structures reveals dynamic motions as a fundamental element in the molecular foundations of biology.

Im Focus: Milestones on the Way to the Nuclear Clock

Two research teams have succeeded simultaneously in measuring the long-sought Thorium nuclear transition, which enables extremely precise nuclear clocks. TU Wien (Vienna) is part of both teams.

If you want to build the most accurate clock in the world, you need something that "ticks" very fast and extremely precise. In an atomic clock, electrons are...

Im Focus: Graphene sets the stage for the next generation of THz astronomy detectors

Researchers from Chalmers University of Technology have demonstrated a detector made from graphene that could revolutionize the sensors used in next-generation space telescopes. The findings were recently published in the scientific journal Nature Astronomy.

Beyond superconductors, there are few materials that can fulfill the requirements needed for making ultra-sensitive and fast terahertz (THz) detectors for...

Im Focus: Physicists from Stuttgart prove the existence of a supersolid state of matte

A supersolid is a state of matter that can be described in simplified terms as being solid and liquid at the same time. In recent years, extensive efforts have been devoted to the detection of this exotic quantum matter. A research team led by Tilman Pfau and Tim Langen at the 5th Institute of Physics of the University of Stuttgart has succeeded in proving experimentally that the long-sought supersolid state of matter exists. The researchers report their results in Nature magazine.

In our everyday lives, we are familiar with matter existing in three different states: solid, liquid, or gas. However, if matter is cooled down to extremely...

Im Focus: World record for tandem perovskite-CIGS solar cell

A team headed by Prof. Steve Albrecht from the HZB will present a new world-record tandem solar cell at EU PVSEC, the world's largest international photovoltaic and solar energy conference and exhibition, in Marseille, France on September 11, 2019. This tandem solar cell combines the semiconducting materials perovskite and CIGS and achieves a certified efficiency of 23.26 per cent. One reason for this success lies in the cell’s intermediate layer of organic molecules: they self-organise to cover even rough semiconductor surfaces. Two patents have been filed for these layers.

Perovskite-based solar cells have experienced an incredibly rapid increase in efficiency over the last ten years. The combination of perovskites with classical...
