- Systematic review evaluates effects of smoking cessation or switching to e-cigarettes on vascular health.
- 23 studies with 11,702 participants included, showing improvements in vascular function markers like PWV, AIx, and FMD.
- Improvements observed within one month and sustained up to 24 months post-cessation.
- Certainty of evidence varied from very low to moderate, with RCTs on FMD showing moderate certainty.
- E-cigarettes showed potential benefits for vascular function, but long-term effects remain uncertain.
- Combustion, not nicotine, may be the primary driver of vascular impairment.
- More robust, long-term studies needed to confirm findings.
