Welcome to HCM,
You have Hypertension
and had Atypical chest pain or symptoms it is good that you are investigated and ruled out of any significant heart disease
Later on you can get your 2 D Echocardiography
if not already done and stress test to screen for IHD although gold standard for coronary artery disease is coronary angiography you can discuss with your Cardiologist.
you have some anxiety and PVCs beta blocker
as anti hypertensive good choice but if you have problem with one you can ask to change it to your cardiologist there are many good agents.
There is possibility of cold extremities due to beta blocker it is not very common.
If you do not need anti anxiety drug your doctor is best person to decide, if you feel you can always take second opinion
