This is my second admission for unstable angina with ecg shown inversion of "t" waves from v1-v4. stress test done-normal. should i go for angiogram?

Yes probably: If you have been admitted with unstable angina two times with inverted t waves in those leads (especially if deep and symmetrical) and an alternative cause has not been established, a definitive study such as an angiogram or perhaps a cardiac ct angiogram would be most frequently recommended.

Yes, I'd go for an: Angiogram esp. If u have risk factors for heart disease. What's the finding on the echo?Discuss with your primary dr and cardiologist about their next plan. Take care! http://emedicine.Medscape.Com/article/159383-workup.
