Hi John,
Welcome to the club. I survived a heart attack and emergency quintuple bypass surgery four years ago when I was 67. I have been and still am a lifelong athletic person. I had no prior symptoms, but did have medically controlled hypertension and my father had a heart attack when he was the same age as me, so it wasn't a total shock. By the way, he never had a second heart attack and died at 92 from Alzheimer's. Personally, I would prefer to die a few years earlier from a second heart attack, but I digress.
It sounds to me as though your current symptoms are perfectly normal and very similar to what I experienced in my first year post-surgery. You do need to be really, really careful about the lightheadedness so that, unlike me, you don't wind up passing out, cracking your skull and getting CT scanned at the hospital to ensure that you didn't suffer a brain bleed. That happened to me right about eight months post-surgery. My guess is that the lightheadedness is a result of your blood pressure medication dosage and that you need to discuss this with your cardiologist. Especially now that you've transformed your diet, you may need a lower dosage. I also suggest you buy a home blood pressure monitor and check your pressure each day, especially an hour or so after you've taken your blood pressure meds. These home devices aren't the most accurate things, but they're better than nothing and, if you take your pressure enough, the results tend to average out and give you a decent idea about whether you're too low or too high.
Like you, I also had some muscle pain in the chest area for a while, and then it went away, never to return. Around three months post-surgery, I resumed strength training several times a week, including bodyweight exercises and heavy weigh training (light compared to when I was in my prime but heavy for a now 71 year old). I also walk and/or cycle every day, weather permitting here in the Northeast.
Good luck healing, and please keep us posted.
Ira
