TMT high probability for Induc Ischemia.

Dear Doctors and experts, I have recently got my annual health check done and my TMT came out as high probability for Inducible Ischemia. TMT Report Monitoring Leads: 12 Grade Achieved : 16 METS : 12 Total exercise time : 10.12 Reason for terminating: Fatigue . Actually I reached maximum pulse rate while doing stage 4 so terminated. Impression: High probability for Inducible Ischemia ST depressions noted during stage 3 in V4-V6 lead II-III aVF ECG- Sinus Tachycardia, T Inversion in V3-V6 I am currently on Rosuzun CV 10 and Udiliv 150. Doctor suggested to take this medication for 2 months and repeat TMT. Please suggest if I have to get Angiogram immediately. Is this mild positive ? What are the chances of blockages? I have high cholesterol problem since age 25 and have been taking statins (multiple courses, not taking throughout the year) Note: I have a family history of heart disease, my father underwent bypass at a younger age of 43.
