I've seen the following about collateralization:
".....specifically, myocardial spasm and hypoxia secondary to myocardial infarction or acutely stressful exercise"
might leed to that and the third item on that list probably has a lot to do with your callaterals opening, but they spefically don't say, just any exercise will do.
Well, I certainly hope that you will overcome this physically and , I think that is very important, mentally
Wow Ed glad your still with us and prayers you get better
There seems to be a kind of agreement among some Doctors that exercise levels has an association with collateral vessel development, but research seems to suggest that isn't the case. The simple fact seems to be that collaterals open with some patients, but not with others and it seems more related to pressure differentials across the coronary arteries. If pressure greatly reduces in one, and pressure is adequately higher in others, then collaterals are likely to happen. My question is whether people on blood pressure medications would be much less likely to develop these. They exist from birth, but it takes a certain amount of pressure difference at either end of these vessels to decide if they open or not. If blood pressure meds prevent the higher pressure side being adequate, then I can't see how they will open.
I had a heart attack on Wednesday this week, and after 20 minutes the pain stopped due to collaterals opening. My blood pressure was naturally quite high, because I had not been taking my medications. Now, if I had taken them, I am wondering if the collaterals would have opened to save my life. This is a question I will be asking my Cardiologist when I see him in a couple of weeks time.
Sounds like you're doing well, still, great.
I quit smoking at about age 45 and started an exercise program that including working my up to running 3 miles with a heart rate in the 150 to 160 range. This went on for about 20 years and except for a diagnosis of atrial fibrillation at about age 58 (responded to treatment drugs and electrocordioversions) I kept telling myself "I'm not getting older, I'm getter better"...here the better meant physically, running or riding a bike, or hiking.. just physically stornger than when I was younger. Thus exercise extended my feeling young, even younger, and was a big bonus.
At age 67 my mitral valve was bad enough to require surgery, and I can say open heart surgery (except for being frighten before) was a "walk in the park".. and I think that was because I had a strong body, including cardiovascular.
Now at age 74 I am in permanent AFib, but respond well to "rate control" and "clot mitigation" = reasonable heart rate and no strokes. But, I can't run any longer and in fact can't hike up much of a hill, but still doing reasonably well for my age.
In spite of a tendency to high cholesterol, which is well controlled with statin drugs, I have had no problems with blockage. I've had a couple angiograms and many nuclear stress tests.
I am sure if I had not quit smoking and started exercising almost 30 years ago I would be long dead by now.
