Suboxone is ruining my heart

I've been on suboxone for 8 years. Life has been the greatest. However the last two years I've been having intense blood pressure spikes to the point of hypertension crises- which are dangerous. These episodes have been happening more often & I now have pain in my chest, swelling through out my body & can't live my normal life. It's been 3 days now that I've cut my dose completely in half. I've cut coffee. I've cut everything that will mess me up. Im posting because I'm frustrated. I've been seeing a cardiologist for 2 years & he always says he can't find anything wrong with me. I find that to be bullshit dude! Since the last episode I've had, I've made an appointment to get ANOTHER ECHO done. Im gonna lay it all out to my cardiologist & primary care provider. I have a plan now. I've been at 16 mgs for a long time. So I've now cut to 8 mgs. It's kicking my ass. But I don't want to die. I have babies. I think this is all happening for a reason. I dont know. I guess I just need some advice, some other inputs.

Thanks guys.
