Coronary Heart Disease in Relation With Coronary Arterial Patterns
Journal Title: IJSR-International Journal Of Scientific Research - Year 2016, Vol 5, Issue 12
Abstract
Anatomy of coronary arterial patterns was studied in 288 human hearts procured from dissection room cadavers to find out relation of coronary heart disease with various coronary arterial patterns. It was observed that 83% hearts showed right coronary arterial dominance while in 16% hearts left coronary arterial dominance was present. Right coronary arterial great dominance was seen in 0.7% hearts and in 0.3% hearts coronary arterial no dominance was noticed. Tunica intimal density of lipid in an artery is directly proportional to pulse pressure of blood in that artery (Keshaw Kumar 2003)1. Ratio of 3:1 existing between pulse pressures in left and right coronary arteries (Keshaw Kumar 2003)2 was due to ratio of 3:1 between wall thickness of left and right ventricles supplied by left and right coronary arteries respectively. In the hearts showing right coronary arterial dominance and right coronary arterial great dominance only anterior 2/3 of interventricular septum was supplied by left coronary artery and remaining posterior 1/3 of interventricular septum was supplied by right coronary artery. In the hearts showing left coronary arterial dominance and coronary arterial no dominance the left coronary artery had to supply entire interventricular septum due to which there was further rise of pulse pressure in left coronary artery causing increased incidence of coronary heart disease.
