Dear Dr Amey,

3D Vaculpgraphy or Cartography is a non invasive way of identification of coronary artery Disease. it is integration of Electrocardiography and special device called Vertical Accelerator Detector that monitors the blood flowing in peripheral arteries during various phase of 1 cardiac cycle.

Similarly 256 cycles were study, with a special predefined algorithm, possible near diagnosis of CAD made.

This procedure is having few Pros and Cons

Pros:

Its a Non invasive

Good Prediction of Diagnosis.

Cons:

Availability of Device.

12 hours of fasting needed.

Vasodilators, AHT drugs, Caffeine should be avoided 12 hrs before the test.

complete study get done in resting so post exercise dynamics can not be study.

How ever it is good tool for Medical campaigns to identify early CAD cases but again for the confirmation CT Coronary Angio, Cardiac Stress Test need to be done.
