To Determine the Difference in the Radiation Exposure, With Low Dose Protocols for Angiography

The radiation exposure of this group would be collected from database of already done studies in the months prior to the initiation of the study (so as to prevent observer bias which may happen once the interventional cardiologist knows his inclusion in study, and may use a shorter or longer cine runs, thus influencing the outcomes). This would best represent the real-world data set, according to the routinely followed standard dose/ older low dose protocol.

a comparative arm where the patients being once eligible for the study; would undergo angiography using the new low dose protocol.
