Myocardial Bridging and 50% blockage of LAD diagonal branch

[davbliss]

Dear all,

The condition that I have currently is myocardial bridging. One doctor view the angiogram frames said that I also have a 50% blockage of LAD diagonal branch. Kinda contradictory as another doctor said I didn't have blockage in that area.
I admitted to hospital 9 times this year since April. I discovered that I have heart problem after a severe shortness of breath and chest pain last August. My condition was quite stable from last August until this April. I was able to walk few kilometres beginning of this year. However, my condition starts to deterioriate this April.
The symptoms are as follows:
Shortness of breath and chest pain when I walked more than 200 metres. The recovery period after I stopped walking was long and bad. However, sometimes, I am able to walk longer. Heart beats was normal. (Around 90 to 100 when walking)
Chest, arm and back pain and discomfort even at rest such as sitting down looking at the computer. This occured quite frequently recently. Almost everyday. The pain and discomfort was mild however it is very uncomfortable. The heart rate during the occurence was normal. Around 75 beats per minute.
Shortness of breath and or chest pain during daily activities such as taking shower, doing house work and etc.
Once in a while, heart rate jumps to 150 beats per minute without any activities. After I rushed to hospital, it took very long (about 2 hours) for the heart rate to drop back to below 90 beats per minute. Occurred 3 times this year.
Feeling dizzy, nausea when there was chest discomfort.
Recently, all the above condition seems to be more frequent. Almost few times a day.

Medications that I am currently taking are as follows:

Aspirin
Ditilazem
Omeprazole
TrimeTazidine HCI MR Tablet
Atorvastatin

I also tried the following medications:
Amlodipine
Nebivolol
Coralan
Concor (Bisoprolol)

My bridge is located at the mid LAD. Actually I did 2 angiograms. One in last August and one this May. Not much changes.

Oh yeah, I also did 2 stress echo this year. One was in this May and another was in September.
For my stress echo in May, it was positive for small area of inducible at 87% PMHR. Basal inferior wall became hypokinetic with stress. Arrhythmia noted: isolated VPC. After the stress echo in May, I did the another angiogram the day after. Results was no significant blockage (But another doctor view said that there was a 50% blockage on the LAD diagonal branch). It also shows Myocardial bridging at mid LAD.  

I repeated another stress echo this September. The summary of the stress echo in September is as follows:
Negative exercise stress echo for inducible myocardial ischemia at 90% MPHR. Satisfactory exercise effort tolerance. (Bruse protocol stage 4) No arrthythmia.
There is some up-sloping (S-T Changes) in stage 3 and 4 and Depression (S-T Changes) during recovery.
Echo findings: Tricial mitral regurgitation, trivial tricuspid regurgitation and trivial pulmoic regurgitation.

So far most of the doctors said that myocardial bridging is benign and won't cause the symptoms. Some even said all the symptoms are inside my mind. How could it be? I hope it is inside my mind but it did not look like that. I really can't cope now. I am very sad. I can't really work. I admitted hospital 3 times last 2 weeks. I just got discharged yesterday. It seems like there is not much hope.
I always get shortness of breath and chest pain even at rest. The shortness of breath was severe. The pain usually radiates to the arm, back and hand. I really need a solution. My family needs me.
Thanks for reading.

Myocardial bridging in many cases may not cause any symptoms, however in some it can cause symptoms.  It depends what artery and what location the bridge is.  Coronary Artery Angiogram (heart cath) can identify the tunneled areas and through some specific attention and testing to see if there's a pressure drop through the bridged area can help determine if the bridge is a problem.  The bridge can develop a "milking" effect of the artery squeezing it during contraction, slowing blood flow.  The invasive cardio should run a Fractional Flow Reserve to check for changes  and if they are in the normal range between Diastolic and Systolic function.

If you're not feeling right, and don't like the answers given to you get another opinion.

My myocardial bridge is also around 70% to 80% during systolic. I have been changing doctors recently and went to few different hospitals. Yeah, it is quite costly. I admitted hospital very frequently. Around once a week excluding ER.
I think we can't give up. We can find one doctor that take it seriously.
Maybe surgery is the last resort. Did you take any medication?

I to have myocardial bridge with 70 % & 40 % blockage in pumping stage of the left anterior descending coronary artery. I have been suffering from shortness of breath chest pain and fatigue for last 18month's. Doctor just keeps saying that it is not causing my symptoms yet they can find anything else wrong with me. Why don't doctors take it serious?

I went to ER again on Wednesday. And I got pain these 2 days too. Seems like there is no concrete solution.
Anyway, Merry Christmas everyone.
