2 Dec 2024 • A study of 4,189 participants from the Jackson Heart Study reveals that cigarette smoking significantly increases the risk of heart failure (HF), including both preserved (HFpEF) and reduced ejection fraction (HFrEF) subtypes.

• Current smokers faced higher HF risks, particularly for HFpEF, regardless of baseline lung function.

• Smoking intensity among current smoking and pack‐years among ever smoking were associated with incident HFpEF, but not with HFrEF.

• The prevalence of obstructive and restrictive lung dysfunction was comparable between the groups, but the prevalence of mixed lung dysfunction was higher in the current smoking group

• The study also highlights the critical importance of smoking cessation: while HF risk decreases over time after quitting, more than 20 years of abstinence is required to match the risk level of non-smokers.

Given the disproportionate HF burden among adults, targeted smoking prevention and cessation strategies are vital for reducing health disparities.
