Key result
In women, living with a smoker for 30 years or more increased the risk of incident myocardial infarction by 40% (HR 1.4, 95% CI 1.1-1.9), whereas the effect in men was largely explained by their own active smoking.

Does active and passive smoking increase the risk of myocardial infarction in men and women?
Hazard Ratio: 1.4 (95% CI 1.1–1.9)
p-value: p=0.004
Passive smoking is an independent risk factor for myocardial infarction in women, increasing risk by 40% after ≥30 years of exposure, whereas in men the risk is largely explained by their own active smoking.
Iversen et al. (2013) conducted a cohort in Myocardial Infarction (n=24,968). Active and passive smoking vs. Never smokers / Never exposed to passive smoking was evaluated on Incident myocardial infarction (HR 1.4, 95% CI 1.1-1.9, p=0.004). In women, living with a smoker for 30 years or more increased the risk of incident myocardial infarction by 40% (HR 1.4, 95% CI 1.1-1.9), whereas the effect in men was largely explained by their own active smoking.
