Cardiovascular diseases are the world's leading cause of disability and death, and are responsible for nearly a million deaths each year in the U.S., and new research suggests the risk of stroke and other life-changing health events are not solely influenced by our genetics and family history.
Dr. Sanjay Rajagopalan, director of the Cardiovascular Research Institute at the Case Western Reserve University Reserve School of Medicine, said other factors are involved.
"Things in your environment might also play a role in raising the likelihood of somebody having a stroke," Rajagopalan pointed out. "Those factors are things like air pollution, certain types of toxins in the environment, mostly chemicals, for instance."
May is Stroke Awareness Month, and health professionals are reminding Americans tobacco use, lack of physical activity, high blood pressure, high cholesterol and diabetes are major risk factors to be addressed.
Signs someone could be having a stroke and needs immediate emergency care include loss of speech, vision or the inability to move their arms or legs or maintain balance.
Scientists said turning the tide on pollution-related strokes and other cardiovascular disease will require large-scale reduction of air pollution by rapidly transitioning to clean energy sources such as wind and solar.
Rajagopalan added the good news is genetics are not a trap into which we are hard-wired.
"It's almost like genetics loads the gun, but the environment pulls the trigger," Rajagopalan stressed. "It's almost as if you are programmed or primed, but nothing will happen unless there are other factors that conspire with your loaded genetics."
Exposure to air pollution can be at least partially mitigated by installing hepa and other air filters in homes, and Rajagopalan advised getting more exercise, reducing fatty foods and adding more vegetables to your diet can also tilt the odds in your favor.
"If you're genetically programmed to have a condition but you work around it -- by exercising, eating right -- you can decrease the risk that genetics confers on you," Rajagopalan concluded.

Seven cases of H5N1 avian flu have been reported in Michigan since Dec. 16. The first case was discovered at a poultry facility in Ottawa County.
Avian flu circulates in wild birds and can infect poultry, causing illnesses classified as highly or low pathogenic. Michigan's first cases in 2022 introduced a highly pathogenic strain.
Dr. Kimberly Dodd, dean of the College of Veterinary Medicine at Michigan State University and an infectious disease expert, explained why the initial outbreak was unique.
"Generally, once it comes to wintertime the number of cases drop off and sometimes that's all we see at the outbreak, and it's resolved," Dodd noted. "In this case, the outbreak continued over the winter and spread across the entire country."
The recent outbreak has affected more than 340,000 birds. Early findings showed the virus also infecting wild mammals, especially young carnivores and scavengers, later spreading to marine mammals near infected waterfowl.
As of now, avian flu has been detected in 30 dairy cattle herds across Michigan. The initial case, reported in March 2024, marked the first instance of avian flu in dairy cattle in the U.S. Since then, the virus has spread to additional herds around the state. Dodd pointed out dozens of domestic and wild cats were also infected after the virus spread to dairy cattle.
"We think this is primarily due to the fact that these barn cats may have access to raw milk on the farm," Dodd emphasized. "We know that raw milk contains high levels of virus."
The Centers for Disease Control and Prevention has reported 67 confirmed human cases of avian flu in the United States, with one death reported in Louisiana. However, the CDC views the situation as a low health risk to the public.

The Medicaid and CHIP programs are vital to rural Missouri, according to a report that says reliance on this safety-net health coverage is much higher in small towns than in cities - especially for children.
The Georgetown University report says proposed federal cuts threaten rural communities, where nearly 41% of children rely on Medicaid, compared to 38% in metro areas.
Dr. Shanon Luke, a pediatrician at a Federally Qualified Health Center in rural Missouri, said her clinic is essential to a community where the nearest hospital is 45 minutes away.
"The clinic being open is incredibly important to these kids receiving healthcare," said Luke. "Having Medicaid allows them to come in for their well-child checks, and for us to do some monitoring and treating of things before they get to scary points."
The report says to stay afloat, many rural hospitals have already been forced to close less profitable units. In 2022, 52% eliminated their maternity wards, compared to 36% of urban hospitals.
The report also reveals disparities, with about 40% of American Indian and Alaska Native people more likely to live in non-metro areas without access to adequate healthcare.
Joan Alker is the executive director and co-founder of the Center for Children and Families at Georgetown University. She said Medicaid helps recipients through much-needed preventive care.
"People wind up sicker and then, they're in the emergency room," said Alker, "and children can't get their asthma inhalers and they miss school."
Statistics show Medicaid helps prevent medical debt, covers most nursing home residents, and funds a significant portion of births and maternal care - issues Dr. Luke said her patients are familiar with, firsthand.
"For our families, both financially and medically, as well as mentally," said Luke, "it's really important to know that they have that coverage."
Just over 24% of Missouri's population lives in rural areas.

This month is National Blood Donor Month, and blood donor groups are making sure people know the importance of giving blood.
Blood can't be manufactured, so people need to donate blood at their local blood bank. Nearly 400 people a day donate blood to the American Red Cross in the DMV metro area.
Bethany Bray Patterson, communications director of the National Capital and Greater Chesapeake Region of the American Red Cross, said donor blood is used in a variety of medical situations.
"Donated blood," said Patterson, "goes to people who are heading into surgery, fighting cancer, newborn babies in the NICU and people who are living with sickle cell disease and other chronic illnesses."
Patterson added that someone in the U.S. needs a life-saving blood transfusion every two seconds.
However, only 3% of eligible donors donate each year. According to America's Blood Centers, if just 1% more of Americans donated, blood shortages would be alleviated.
Patterson said the blood supply in the country is stable, but organizations like the Red Cross are also on the look out for universal donors.
"There is an increased need right now for type O blood donation, and platelet donations," said Patterson. "Type O blood is always in demand. It's often going out to hospitals faster than it's coming in through blood donation, because it is the universal blood type. It's used the most by hospitals."
You can find blood donation locations and schedule an appointment at RedCrossblood.org.
