First of all, I am not a doctor therefore my opinion should not be taken seriously. Always consult with your primary care provider about your medical issues. Having said that, if I were you, I would consult with my Dr. and weigh my options and figure out which way to go. If money is not an issue I would do a complete overall of my cardio-vascular health through the relevant tests.
I wish you all the best and I will be praying for your improved health.
