| Sumario: | Objective Smoking is a risk factor for coronary artery disease (CAD) and a known factor influencing the severity and pattern of CAD. We summarized evidence regarding the effect of smoking on the number of occluded coronary arteries and the severity and pattern of CAD. Methods We extracted data from observational studies reporting the pattern and severity of CAD in smokers. The quality of studies was assessed using the Strengthening the Reporting of Observational Studies in Epidemiology checklist, and results are reported in the Garrard table. The review process followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. Results We screened 11 studies including 6037 samples. Six studies reported no relationship between smoking and the number of damaged arteries. One study reported that smoking was related to occlusion in the left anterior descending artery, but there was no relationship between smoking and the location of occlusion in the arteries. Smoking was related to CAD severity in five studies. Conclusions Smoking was found to be related to CAD severity and location of the damaged artery in the heart. However, there was no significant association of smoking with the number of damaged arteries and location of arterial occlusion. |
