Coronary artery disease is the major determinant of human survival & health in the modern era!Obstruction of a coronary artery either sudden or gradual forms the basis CAD .
When a free flowing river stumbles upon an obstruction , it does not die , it finds it’s way to the sea. Similarly ,God is kind enough to provide alternate channels for blood flow to heart at times of crisis .Contrary to the perception , collaterals develop not only in chronic occlusions but also in acute occlusions.
A person who dies due to a primary VF few minutes after a acute occlusion is in all probability experiences his fate ! While those who survive are protected by the immediate recruitment of collaterals and this prevents the remote myocardium from triggering a VF.
In chronic CAD, the collaterals are much more effective. Now we have evidence with OAT and COURAGE trials for this.Some times , the LAD is fully supported by the RCA the flow is better than a graft.
Coronary collateral circulation is most poorly understood phenomenon in cardiology. But it comes as helping hand whenever required only for those humans who deserve it ! God has kept the secrets with himself !
A excellent article on natural by pass from circulation patient pages.
