Is Stint Possible With Diffused Arteries?

The calcium score was done by certified hospital. Having such high score (1200) caused me a great deal of concern. I finally ended with an echo with doppler which produced negative results, The EKG portion of the excercise Coariolite was positive for ischemia despite achieving 13.4 METs of workload on the treadmill with no chest pain and an ejection frraction of 65%. A coronary angiogram was orderd and showed moderate diffuse disease throughout all three coronary arteries including LAD, left circumflex and right coronary artery. Preserved LV function and diastolic pressures were normal. For thsose that might be able to help please provide feed back on the following: 1-What are the surgical options that are available if chest pain or shortness of breath develop? 2- Are stints possible with diffused arteries?I am currently on 40 mg Crestor and 145mg tricor , watching my diet and pursuing aggressive life style changes.
