You are welcome, and at "our age" it is always best to get symptoms check by a doctor. I can't say I am very good at following my own advice.
Good luck,
Thanks Jerry, interesting...hmm. I'll try aspirin and see my doc next week.

Fasting if it causes stress, mental and physical, could cause some heart rhythm problems.
If you can take aspirin without stomach or other problems, I think it would be a good idea to start on an aspirin a day, then make an appointment to see a doctor to get a diagnosis.
Atrial fibrillation is more likely with age, you at 72 are in that group. Leaky valves, there are at least 4 of them, best I can recall, is rather common and usually not serious.. unless it gets too leaky. This happened to me with my Mitral Valve which was repaired with surgery a number of years ago.
