The effect of coronary dominance on mortality in patients with acute coronary syndrome (ACS) remains unclear. We performed a meta-analysis to evaluate the effect of coronary dominance in patients with ACS.Several data sources were searched for studies which compared studies that compared outcomes between right and left dominant coronary circulation in patients with ACS. The measured outcomes were in-hospital, 30-day or long-term mortality as reported in individual studies. The Generic inverse variance method was used in a random-effects model to pool mortality as an outcome. Odds ratio (OR) was calculated for mortality in the left dominant circulation relative to a right dominant one. Sub-group analysis was performed after stratification of mortality by duration.A total of 5 studies with 8 comparisons and 255,718 participants revealed an increased risk mortality (OR = 1.27 (95
