Dr. Martha Gulati will always remember whenever she first saw a youthful sound competitor pass on from heat stroke.
It was in Chicago in 1995 in the middle of a heat wave that would eventually claim the lives of about 700 people. In the decades that followed, Gulati watched in alarm as the climate warmed and heat waves intensified.
“The medical community was unprepared for what these temperatures would do to the people we were eventually learning on the fly,” said Gulati, who is now an associate cardiovascular center at Cedarssinai Medical Center in Los Angeles. Director and President of the American Society of Preventive Cardiology.
Since that heat wave in 1995, climate change has intensified around the world, including wildfires, hurricanes, droughts, heat waves, and cold famines and droughts. The medical community is seeing rising rates of heart disease as a result of these extreme changes.
Gulati said that the world we are living in now is not a very hospitable environment for the heart. With coronary illness anticipation we center around controlling circulatory strain and lipids however we should think about different parts of avoidance, like our current circumstance.
According to a study published in the Lancet in 2020, 62 percent of deaths due to climate change were from heart disease.
Evidence suggests that air pollution exacerbates heart disease, congestive heart failure and insulin resistance, said a cardiologist at University Hospitals in Ohio and an assistant professor at Case Western Reserve University School of Medicine. Sadir al-Kindi said.
Particulate matter, minuscule particles in the air that are imperceptible to the unaided eye, are made by ozone depleting substances and fossil fuel byproducts.
These particles can enter your lungs and bloodstream and wreak havoc on tissues important to a healthy cardiovascular system. Over time, prolonged exposure to pollution can lead to an increase in high blood pressure and sleep disturbances.
When these pollutants are inhaled, the body causes stress and inflammation that can result in cardiometabolic syndrome, said Dr. Kai Chen, assistant professor in the Yale School of Public Health and director of research at the Yale Center on Climate Change and Health.
However, according to a June study in Nature Reviews Cardiology, there has been research to suggest a closer relationship because areas with extreme heat or cold temperatures had dangerously high episodes of heart attacks.
It is not clear exactly why the change in temperature is associated with higher rates of heart attacks. Experts believe that changes in temperature affect the body’s ability to regulate normal temperatures in response to extreme temperatures.
Al-Kindi said a concept called climate punishment could explain these patterns. He said climate change has enabled extreme weather conditions to increase and deliver invisible molecules that are harmful to our bodies.
A study published earlier this month in the journal Nature Cardiovascular Research found that drugs used to treat heart disease may also work differently during heat waves.
Chen, the study’s lead author, found that patients who were taking two drugs used to treat heart disease had higher rates of heart attacks with record heat waves.
People who were on beta blockers and antiplatelet drugs, regardless of age, had recurrent heart attacks, Chen explained.
What Chen said is interesting is that young people taking the same drugs that we don’t normally expect to have heart disease have more episodes of heart attacks than those taking these drugs. woo
Al-Kindi, who was not involved in the study, believes this paradox of drugs used to treat heart disease may lead to more heart attacks on extremely hot days that affect our nerves. Can do. Is. Shuts down the system.
While keeping away from cigarettes, practicing good eating habits, resting soundly, and practicing are ways of forestalling coronary illness, specialists concur that safeguarding yourself from the impacts of environmental change is crucial for your heart wellbeing.
