Dr. Teo and colleagues studied tobacco use patterns among 12,133 patients with a first acute MI and 14,435 age- and sex-matched community-based control subjects who had been recruited in 52 countries on virtually every continent. In their analysis of by far the most common use, cigarette smoking, which was adjusted for demographics, geography, and other variables:
Overall, the risk (odds ratio [OR]) of nonfatal MI among current smokers was 2.95 relative to that of never-smokers (P < .0001). Risk was higher in younger smokers than in older ones and lower in women than in men.
The risk reached only 1.85 among former smokers within 3 years of quitting, although it persisted at 1.22 even among those cigarette-free for 20 years.
The MI risk climbed from 1.63 among persons smoking 1 to 9 cigarettes per day to 4.59 for a rate of more than 20/day (P < .0001 for both findings). Every additional daily cigarette corresponded to a 5.6% jump in risk, according to the analysis.
Less than half of controls reported no exposure to second-hand smoke. Those exposed only 1 to 7 hours per week showed a significant MI risk of 1.24 relative to those without any exposure. The risk reached 1.62 for those exposed to more than 21 hours per week.
