The Impact of Wildfires on Health

Dear readers,

We are watching the tragedy in LA and the wildfires, but two recent articles highlight the likely spike in disease states due to the poor air quality in the region. Prayers. Two interesting research studies on lipoprotein(a) suggest a relationship between aortic root enlargement and atrial fibrillation complications. This is concerning, especially considering that 20-25% of people inherit this cholesterol molecule. This week, we are reminded that green tea and coffee (in the AM) are healthy, while sugary beverages are not. Finally, over half of heart patients do not meet the goal of an LDL-C < 70 mg/dL, particularly in women and Black Americans. We have a lot of work to do, and many of us are now shooting for an LDL < 55 in CAD patients.

Be well,

Joel Kahn, MD, FACC

    • However, Mendelian randomization studies advocate a causal association between high Lp(a) and AF. Data suggests that AF patients who experience a stroke or other thromboembolic events tend to have higher Lp(a) concentrations than those without such events.

    • About 25% of the U.S. population has high cholesterol, which contributes to 3.2 million deaths a year. Guidelines recommend lowering low-density lipoprotein cholesterol (LDL-C), known as “bad cholesterol,” below 100 mg/dl for healthy adults, and under 70 mg/dL for those with atherosclerotic cardiovascular disease (ASCVD).  

      But data from 216,000 heart disease patients with ASCVD at five different health systems showed 60% had LDL at or above this level. Even when high cholesterol was detected, most patients didn’t receive additional treatment, said first study author Nishant P. Shah, MD, a preventative cardiologist at Duke Heath.
