Long term effect or side effect

I am 40 years old and married. I do not smoke but I occasional drink. I have white coat hypertension. Every time my doctor checks my blood pressure, it would be 170/100 or sometimes 180/120. But when I personally check my own BP using a digital BP instrument, my BP is 120/80 or 130/80. My doctor also made me do a 2D echo test and he said that I have mild mitral regurgitation. Right now I am taking Provasc 5mg in the morning and Tenorvas (atenolol) 50 mg at night. I want to know if taking both these medicines has a long term side effect. Is it ok for me to take them both for maintenance...long term? Any side effects? If I were to discontinue one, which one? Please advise....Thank you

Why are you thinking about discontinuing one of the medications?  The atenolol is a beta blocker and cannot be stopped suddenly.  Your heart gets used to the beta blocker.  The Provasc is a calcium channel blocker which is also important to reduce blood pressure.  Normal BP is 120/72 and people with heart disease usually take medication to bring the BP below what is normal.  I have known relatives on these medications for years and I can say that they lived a long life on these medications.  The medications did not harm their heart and they passed away from other causes (not their heart disease).  Heart medications help people to live a long life, especially if they start their medications at a young age.  My uncle started his medications in his teen years and lived to be 75.
