Beta blockers have many potential benefits that promote beneficial remodeling including reduction in cardiac response to stress hormones. They also have some effects directly on cells such as fibroblasts, but they are better known for blocking the signals that promote such activity.
I am sorry. I am not an expert in orthopedic issues. Certainly discuss this with your surgeon.
Creatinine elevation usually goes along with kidney disease. Diabetes is one of the potential causes. You should discuss this with your doctor.
That does not sound cardiac. A simple test is to have a physician check your lower leg pulses and blood pressures.
In general, exercise 5 times a week for 40 minutes getting your heart rate up to about 70% predicted for that period. Walking, jogging, biking, and gym equipment are reasonable. Also consider adding in low weights. Most importantly, find something you enjoy (group exercise, hiking, whatever).
Some of it depends on things like your left atrial size and presence of other cardiac issues, but studies generally show that a first ablation success is about 50-60%. Even if unsuccessful most patients are better (controlled on drugs, become paroxysmal, etc.) After more than one ablation, your success could be up to about 85 percent.
I do not believe that there is a known risk to the aneurysm itself from afib episodes.
Diazepam is not a heart medication. It is a medication used for anxiety or seizures. I do not prescribe it for afib. Some will give it for anxiety associated with rhythm disorders, but this is best done under the care of a psychiatric specialist.
There is no particular cause for afib, but there are risks for developing it. People with any heart disease, including slow heart rates requiring pacemaker are at risk for developing a fib. There are also many triggers (alcohol, exercise, stress), but these are fairly individual.
Yes. Afib that goes back into normal rhythm is called paroxysmal. It will likely come back at some time though. If you have stroke risk factors (diabetes, high blood pressure, previous stroke atc.) then medications like Pradaxa and Coumadin reduce the risk of stroke. Rhythm medications and ablation are used to reduce the frequency of the afib.
