Association of Cigarette and E-Cigarette Use with CVD Biomarkers 

Although the prevalence of cigarette smoking has significantly declined from nearly 21% of the U.S. adult population identifying as smokers in 2005 to only 14% today, an estimated 34.1 million adults still currently smoke cigarettes. In addition, many have transitioned to the use of electronic cigarettes in hopes of reducing cardiometabolic risks. However, the cardiovascular toxicity of electronic cigarettes is not well understood and comprehensive population data assessing their adverse effects remains sparse.

Researchers continue to investigate the repercussions of both cigarette and e-cigarette use, including the specific cardiovascular disease biomarkers that can act as predictive factors for CVD events. Inflammation and oxidative stress have been identified as key contributors of smoking-induced cardiovascular disease prompting scientists to evaluate these measures in current smokers. Findings recently published in Circulation reveal that similar levels of inflammation and oxidative stress biomarkers can be observed in patients who use both electronic cigarettes and cigarettes and those who exclusively smoke cigarettes.

Gaps in Public Knowledge of Basic MI Symptoms

Approximately 1.5 million cases of myocardial infarction (MI) occur in the United States per year and despite significant declines in age-adjusted mortality rates attributable to acute MI since the 1970s, the overall rate of MI-related deaths has not declined.  Heart disease remains the number one cause of morbidity and mortality in the nation, killing approximately 650,000 U.S. adults per year. While prompt recognition of MI symptoms is essential to improving health outcomes and ensuring timely access to emergency cardiac care, MI patients continue to have a delayed presentation in the hospital – a large number die before even reaching the hospital.

A lack of awareness may be to blame. Results of a recent study, published in JAMA Network Open reveal that many adults in the United States are unaware of the basic symptoms indicating myocardial infarction or what to do if they experience them.
