Do beta blockers cause cardiac remodeling because of fibroblasts
2012-11-28 Answered By : Dr. J.David Burkhardt M.D., F.A.C.C. F.H.R.S.

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.

Hi Doctor, My father recently underwent a hipsurgery where a bipolar prosthesis was inserted in his leg. It has been more than 11 days since the surgery. He is only able to do limited exercise. He is diabetic and has high blood pressure (170/80). Should I give him aspirin for anti- coagulation , Tiotropium bromide for bronchodilation and Telvas AM (Telmisartan + Amlodipine ) for blood pressure. Thanks Regards Manoj Thankyou for the answer. When my dad tries to walk using a walker, he is able to walk only for 5 min. My father says pain and lack of energy are the main reasons for this short duration of the walk. However, after walking when he sits down on the bed, he perspires profusely. Before his hip surgery, his haemoglobin level was low at 9.8. Thats why ~600 ml of blood was transfused before surgery. What do you think is the reason for excessive perspiration? My dad thinks that this may be another reason why he cannot walk more. Your reply is greatly appreciated.

I am sorry. I am not an expert in orthopedic issues. Certainly discuss this with your surgeon.

Hi,I am having a creatinine level of 2.6 however my urea is within normal range.I take medicines for cholesterol -tonac tg,Diabetes-Novoronn and glimy,Anti coagulation-Preva As,Admenta,And anti depressant-Citopam 10.Also For pressure I Take Losar-25.Can you tell me the reason for this rise in creatinine level and it is continuosly rising last time it was 2.1 and now 2.6. kindly suggest me.?

Creatinine elevation usually goes along with kidney disease. Diabetes is one of the potential causes. You should discuss this with your doctor.

Hello Doctor. I am a 39 year old woman with no personal history of cardiovascular disease and blood pressure in the normal range (but my father has had several heart attacks, TIA s, and one major stroke that occurred while he was having an angiogram- left hem; approximately Broca s area). I recently began a full-time college teaching position, and have begun suffering acutely from occasional stress-related insomnia , combined with lack of sleep simply due to work load... this seems related to other symptoms that seem like panic attacks, along with the general (sometimes intense) discomfort that goes along with fatigue. In the last few weeks I noticed that sometimes my left big toenail becomes blue, but it recovers its (more) normal shade after I rub my feet and legs or warm up in the shower. Could this be a sign of cardiovascular issues? Is the left lateralization significant?

That does not sound cardiac. A simple test is to have a physician check your lower leg pulses and blood pressures.

Hi Doctor,my father detected with tmt borderline positive inducible ischemia so what should i do to prevent coronary heart diseases ,what kind of exersise i should recommended?

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).

Hi I\'ve been in permanent Afib for 6 years, I am a 61 year old female. What chance does ablation have of curing me?
2012-11-28 Answered By : Dr. J.David Burkhardt M.D., F.A.C.C. F.H.R.S.

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.

Hi. I have infrequent episodes of Afib (once every 2 months or so) where my heart beat suddenly jumps to 180-200 beats per minute. I also have an aortic root aneurism of 4.6cm. I take 75 mg of metoprolol daily. My question is do these episodes of Afib pose a danger to my aneurism?
2012-11-28 Answered By : Dr. J.David Burkhardt M.D., F.A.C.C. F.H.R.S.

I do not believe that there is a known risk to the aneurysm itself from afib episodes.

Hello Doctor. During every episode of AF recently, I've taken a 10mg diazepam and the episodes subsided within a short time period, always before I could get to the cardiologist's office or hospital for cardioversion. How does this medication work, if it is the critical med, to correct AF? kindly suggest me.?
2012-11-28 Answered By : Dr. J.David Burkhardt M.D., F.A.C.C. F.H.R.S.

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.

Hi.Are there any identifiable causes of AF? I have paroxysmal AF. I've had 6 episodes that lasted over 1 hour in past 10 years; over 50% were when I was taking steroids for sinus infections. The others occurred last year when I lost 40 lbs. and my BP was low (below 100/60). It seems to me that anything that increases my HR appreciably will trigger an episode. I also have a pacemaker for tachy-brady syndrome.
2012-11-28 Answered By : Dr. J.David Burkhardt M.D., F.A.C.C. F.H.R.S.

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.

Hello Doctor,Can Afib ever go back to being normal by itself just got diagnosed in physical on EKG by accident cannot feel it on pradaxa and digoxin and hate I'm 73 and read all sorts of things like shorter life and dementia because of it. It scares me doctor not fond of doing procedures.
2012-11-28 Answered By : Dr. J.David Burkhardt M.D., F.A.C.C. F.H.R.S.

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.
