. In 1998 my aotic valve was replaced. In 2010 I had hypertension and blood clots were replaced on brain operation. A pacemaker was implanted to me in 2012 when i complained difficulty in breathing. My ECG showed LBBB, may be I was not aware of it or I may not be knowing. Of late my blood glucose is also showing high values i.e. fasting 110 and pp 150-170 mg and Hba1c is around 6.3-6.6. I am 77 years age now. Would you please advise me on my cardiac and medical problems.
