Short Summary
Main recommendation: People with underlying heart disease, or with risk factors such as older age, high cholesterol, high blood pressure, diabetes, or smoking, should be especially aware of air quality and take precautions on bad air days. Intermountain Medical Center (IMC) researchers found a significant link between short-term air pollution spikes and more hospital admissions for heart failure and severe heart attacks.
Key Points
- IMC studies found a significant link between increased short-term air pollution and admissions for heart failure and severe heart attacks.
- The effect mainly shows up in the most serious type of heart attack, ST elevation MI (STEMI), where a severe blockage in a heart vessel can stop the main pumping chamber.
- Dr. Benjamin Horne and his team have studied air pollution and health along the Wasatch Front for over a decade.
- On bad air days, the team reports consistently higher numbers of patients with heart attack symptoms, chest pain, and hearts laboring to pump blood.
- Air pollution also tends to affect pregnant women, people with asthma, and people with COPD more strongly.
Details Worth Noting
Concrete instructions: Check the daily air quality for your area, and on bad air days be especially cautious if you have heart disease, stroke history, asthma, COPD, or are pregnant. Know your heart risk factors (age, high cholesterol, high blood pressure, diabetes, smoking), since many people with heart disease do not know they have it. Review IMC's free fact sheets for heart disease or stroke, asthma and COPD, and pregnancy by searching "air quality" on IMC's website, and follow the common-sense guidelines they contain. The transcript does not give specific medication, dosage, or activity-limit instructions.
- The team developed a care process model to help physicians discuss what can be done during patient consultations.
- The news segment noted that the current air quality in Salt Lake County was moderate, while the researchers' point is that bad-air days still produce more hospital visits.
- The source is a local news report, and the findings are described as those of IMC medical experts.
Bottom Line
Air pollution spikes are linked to more serious heart problems in the Wasatch Front area, so people with heart or lung conditions or major risk factors should pay attention to air quality and seek IMC's free guidance.
