My TAVR surgery to re replace my mitral valve was 1/30/2025. While our cardiac conditions are different, I will share my thoughts and experiences.
1. Like you, my mornings are the slowest part of my day.
2. My Metropropol was also lowered to 25mg twice a day.
3. Your cardiologist will need to write an order for cardiac rehab. I would write to your cardiologist using the portal and explain why you want rehab. I’m sure they will do it for you.

I have had several heart surgeries. It takes time before your heart can settle down from the trauma of surgery. I would use the portal to report these symptoms to your cardiologist while at the same time resting and taking care of my body and my spirit.
One month post op I still had symptoms. Now that I’m almost 3 months out, I’m so much improved. I believe you just need to give your body time. Also, I make an effort to keep my cardiologist informed. I don’t make unnecessary demands but keep him in the loop of how I’m responding to medications and exercise.
Have you tried walking? It’s so good for your heart and your mind. And, you don’t need a written order from your doctor, just get out there and walk.
I hope this has been helpful and wish you a speedy recovery.
