Would Intake Of Monotrate SR 30mg Cause Headache?

I am 75.8 years, and on 6 May 2011, had PTCA and stenting of proximal LAD done with 3mm x 33mm Bio-flex DES after thrombus aspiration and predialation with 2.75mm ballon. D1 was crossed with Fielder FC and dialted with a 2mm balloon before stenting LAD. LAD stent post dilated with 3.25mm balloon at 18-24ATM with good result. Left Ostium looked hazy with slow clearance. A 4mm x 15mm promos DES was deployed and post dialted with a 4.5mm NC balloon at 18 to 24 ATM. Final angio showed TIMI 3 flow with TMP grade 3 in the lad and no residual stenosis in either of the vessels. CADRF: Mild dyslipidemia. TMT on 7 Sept. 13: - 8 min 12 secs. 107% HR, No ST changes. TMT on 15 Aug. 14: 6 min 20 secs. Mild ST depression at peak but none during recovery. A/P: CAD S/p LMCA and LAD stenting in 2011 for acute MI now stable angina - new and mildly abnormal TMT. I am on following medicines since 26 My 2014: T Ceruvin 75 mg 1 ---0 0 T Ecosprin 75 mg 0 1 0 T Crestor 10 mg 0 0 1 T Monotrate SR 30 mg 1 0 1 T Sleoram 50/5 1 0 1 Pantadac 40 mg 1 0 0 Besides the above medicines, I have been suggested to undergo another angeogram,at convenience,as the TMT indicates minimal abnormality. I led very regular and active life till 2011 and never suffered from any major problem. I hate taking too many medicines. Even after retirement from WHO, in 1998, I continued working with them on ad hoc basis till December 2010. My question is: With host of preventive meidcines I am taking,is another angeogram required? With medicines my BP has also stabilized now. Also since I was put on Monotrate SR 30mg. I am having almost constant headache though tolerable, started passing urine at least four time during night, feel exhausted which some time obstructs my evening/morning walk and yoga, besides loss of and irregular sleep pattern. I shall thank you for your considered opinion which would certainly help me lead a confortable and medicine-free life. Thanks and with regards, Yours sincerely, N.C. Kochhar
