I have a long history of heart disease. Quad-bi pass in 1995. 6 stents since, 2001, 2012, 2010, 2013. have had some mild chest pain the last 6 weeks. had an nuke stress test today. i have mild lateral ishchemia. my cardiologist said to up my dose of amlodipine from 5mg to 10mg, come back end of Jan 2017 for a follow up. they said we probably do not need to cath now. I am worried though. my doctor and hosp is Vanderbilt Heart, so pretty top notch medical care. Thoughts?
