摘要
The dominant artery is one that gives posterior descending artery and supply the inferior portion of the interventricular groove. The dominance can be: right, left and balanced (co-dominant) circulation with several subtypes. The aim of this study was to determinate the dominance patterns of the heart circulation on the angiograms and their represence on sex and age and to determinate their correlation with clinical consequences.
The study included 70 patients with ischemic heart disease (males 50, females 20, age between 33-78 years) who underwent coronary angiography in Heart Centre of the Clinical Center University of Sarajevo in period of 01.04.2011. to 01.04.2012., either for the symptoms of chest pain, angina pectoris etc. The angiograms were analyzed to determinate the dominance patterns of the heart circulation.
Angiograms of 70 patients showed the right dominant type in 50 (71,42%) cases, the left dominant in 7 (10%) cases and the balanced circulation in 13 (18,57%) cases. The most common type of coronary circulation is the right dominant by both sex. Males were majority in this study.. Majority of the patients were in their 5th and 6th decades of life. There is no significant difference in dominance pattern with age or sex. Correlation with clinical consequences was observed through the myocardial infarction and the type of coronary circulation. Myocardial infarction was determinated in patients with left dominant circulation most frequently than in right and balanced circulation.
The right dominant circulation is most common by bouth sex. Myocardial infarction is most common by males and by the left dominant circulation, where clinical consequences were worse and that explains the large area that is vascularisation by left coronary artery and the occlusion occurs most common on the left descending artery.
