Wow. Any mileage warranty?
But I almost didn't make it to my 64th birthday because of the problems I described after my open heart surgery.
Thanks be to God for greater grace. We take making it to this age for granted, when 100 years ago the life expectancy for males was 53.5.
If you have angina and are getting tired, that is a clear sign that you need to get your heart checked out. Don't wait.
I do not plan on any check up, nor using any medicare. I have had angina for years actually, yet have been able to run around or otherwise be active most of the day. I take some Hawthrone Berry and LiArginnine capsules when angina becomes really noticeable. The increased fatigue is what I notice more. Get up about 6AM but usually want a nap about 8PM after eating, but go to bed about 10. .
I never had angina or a heart attack prior to my heart surgery but my cardiologists said I could have had one at any time. I had four coronary arteries that were 80% occluded or blocked when they bypassed them during the surgery.
I am sure I have some blockage, Weight is about 135 and height about 5'4'' so maybe that can help, but prayer for the issue and other things and being in His will in service to Him is what is most important.
The fact that the angina goes away does not mean the underlying reason you are having angina has gone away. It's like taking an aspirin for a splitting headache when your about to have a stroke from a brain aneurysm. You're treating the symptoms and not the underlying problem.
I will just say that I don't think your decision not to go get your heart checked out is a wise one if you care about your health. Your body is telling you in as loud of signals that it can, that you are about to have a full-blown coronary.
If you think you're "tired" now, wait until only a half of your heart muscles are pumping because the other half are dead from the heart attack. You will be bed ridden or, at best, in a wheelchair. An invalid.
My advice again is to go see your doctor. Don't wait.
