Male,57,diabetic,recently got symptoms of angina. angiography suggested. is it safe ? or echocardiography will be better ? i m worried.

Safe with precaution: In your situation, coronary angiography is better than stress echocardiography since it will define the lesion causing angina and also allow intervention if necessary. The primary risk is contrast (dye) overload that can cause kidney injury, but can be minimized if adequate hydration is given around the time of the catheterization. This risk also depends on your baseline kidney function.
