Re: Silent MI at 43? questions.
If you exercise the way you've outlined without having angina, and if your EF is 70%, I wouldn't panic about about cardiac health.
Whether there is damage that might curtail your firefighting career is something I couldn't begin to judge. But I would do a couple of things::
1. Ask your cardiologist for a thallium (nuclear) stress test. This would confirm or disprove the silent heart attack and would show if you have other areas of ischemia which might require further testing (such as cardiac angiography).
2. Get a fasting lipid profile. If your total choloresterol (TC) and low density choloresterol (LDL) are too high, I would ask for a statin for choloresterol reduction. If you bike 30 to 50 miles a week in hilly terrain and do the other exercises you've outlined, my guess is that your high density choloresterol (HDL) will be well above average. It is very desirable for the ratio TC/HDL to be 4.0 or less. And it is also advisable for the LDL to be 100 or lower.
I had a severe MI at age 47, and it wasn't silent, believe me. The bottom part of my heart doesn't work, and I have an aneurism on the heart wall dating from the heart attack. My EF is 35%. I had six bypasses when I was age 55.
But life is good, and I've been able to do what I want in the way of physical work without distress. And I'm now 78 years old and am still perking right along. Had a coronary angiogram a month ago and all my bypasses are still working fine after 24 years.
There is life after CAD if you take advantage of the medical advances and drugs available, and do your part with diet and exercise..
Best of luck to you,
