@lizjlb because on a CT I had in hospital it said extensive calcium build up in arteries. I read that and made appointment with cardiologist. He is the best. Did the echo it said no PH but he went farther and did the heart catheter test which showed the pressure in both arteries were up. My BP was also high. I didn’t have bad restrictions from calcium but did have PH. I’m on 2 meds to lower BP and help my heart beat slower so not such a strain
