Endovascular surgery for acute coronary syndrome with ST segment elevation in patients with multivessel coronary artery disease according to coronary artery dominance
Objective. Define the impact of coronary artery dominance on hospital mortality in patients with STEMI and multivessel coronary artery disease. Material and methods. The study involved 361 patients, who were divided into two groups depending on the coronary artery dominance. The first group included 289 (80.1%) patients with right-dominant. The second group included 72 (19.9%) patients with left-dominant and co-dominant coronary artery dominance. Results. The relative risk (RR) was calculated that to compare hospital mortality between the two groups. RR made 1.4. Further, the Kaplan-Meier curve was constructed for the two studied groups and the Fisher's test and the Cox-Mantel test were calculated. The obtained p-tests were 0.237 and 0.518. Conclusion. Left-dominant and co-dominant coronary artery dominance increase in hospital mortality in patients with STEMI and multivessel coronary artery disease.
