Why the study?
To examine the effect of smoking status, smoking intensity, duration of cessation, and age of initiation on all-cause and cause-specific mortality in cardiovascular disease patients.
Does smoking status, intensity, and cessation affect mortality risk in patients with cardiovascular disease?
Does smoking status, intensity, and cessation affect mortality risk in patients with cardiovascular disease?
Smoking significantly increases the risk of all-cause, CVD, and cancer mortality in patients with cardiovascular disease, but this risk decreases significantly after quitting.
No takes yet. Share an insight, caveat, or question.
Smoking was associated with higher mortality in CVD patients; supports cessation counseling while leaving intensity and initiation questions open.
