Key result
Among young adults under 40 with acute myocardial infarction, smoking was significantly more prevalent in those with obstructive coronary artery disease (73.5%) compared to nonobstructive disease (41.9%).
Why the study?
Coronary artery disease is increasingly observed in young adults with specific characteristics and is no longer an exceptional occurrence.
Observational (n=80)
No
Absolute Event Rate: 73.5% vs 41.9%
p-value: p=0.005
In young adults under 40 with myocardial infarction, obstructive disease is strongly associated with smoking and substance use, whereas non-obstructive disease presents with fewer traditional risk factors.
Smoking was associated with obstructive versus nonobstructive CAD in young AMI; hypothesis-generating and should not yet change practice.

Fennich et al. (2019) conducted an observational in Acute myocardial infarction (n=80). Obstructive coronary artery disease vs. Nonobstructive coronary artery disease was evaluated on Prevalence of smoking (p=0.005). Among young adults under 40 with acute myocardial infarction, smoking was significantly more prevalent in those with obstructive coronary artery disease (73.5%) compared to nonobstructive disease (41.9%).
