CABG

"After six years I have second heart attack.IWMI.Angiography shows all three major vessle blocks to the extent of 90% at near end and 70% block at far end.Physical capacity of body is normal. No pain even during exercise. May be due to colateral circulation. Advised CABG. Fearing problems after surgery not feeling to do that.Please advise."

Swimming causing pressue? How deep are you going? Are you talking about scuba diving here and using gas mixes?

[nagrajjain]

I am not talking about scuba-diving as is evident "under 6feet of water'. Will blood pressure rise or fall and to what extent? If you know please tell me.

Good question.  There isn't decisive reports regarding arterial blood pressure and values during breath-hold diving is scanty. I found some information with the Journal of Applied Physiology. There has been some reports that have taken blood pressure at the water's surface showing slight or no increase in arterial BP, and from a single study of two simulated deep breath-hold dives in a hyperbaric chamber. Simulated dives showed an increase in ABP to values considered life threatening by standard clinical criteria. For the first time, using a novel noninvasive subaquatic sphygmomanometer, we successfully measured ABP in 10 healthy elite breath-hold divers at a depth of 10 m of freshwater (mfw). ABP was measured in dry conditions, at the surface (head-out immersion), and twice at a depth of 10 mfw. Underwater measurements of ABP were obtained in all subjects. Each measurement lasted 50–60 s and was accomplished without any complications or diver discomfort. In the 10 subjects as a whole, mean ABP values were 124/93 mmHg at the surface and 123/94 mmHg at a depth of 10 mfw. No significant statistical differences were found when blood pressure measurements at the water surface were compared with breath-hold diving conditions at a depth of 10 mfw.

Hope this provides the information you ask.

Thank you for interest shown. Now I will tell you my exact observation before I got my second heart attack.
I used to submerge in water till the neck and used to walk in water with reduced weight in water. The floor of water tank being slanting the depth of submersion was getting reduced as I walked slowly. It is unique observation that when water came to the level of my heart and when my heart level came out of water I had a strange feeling of sudden change in pressure. This unique observation I was experiencing dailly for about five days. Then on sixth day while doing the same thing I started feeling mild chaste pain and thinking some thing wrong I came out of water immediately. After five minutes I had severe chaste pain which did not stop after Sorbitate and two ecosprine tabs too.This lead me to ask this question of blood pressure changes in water. Thank you once again. But definitely it needs a lot of thinking and research on the subject.

I am trying to draw some message from your observation. If I understand you correctly, you had no other symptom prior to your second heart attack except your observation in the swiming pool.

I am had MI in 2007, a stented LAD and 100% blocked LCx. My EF is around 30-35%. I do not feel discomfort during my normal walks and I believe that I am fine. But relating to your experience, the symptoms may emerge only under some specific conditions; like in swiming pool in your case.

How to make sure I do not get second MI. Sorry for interrupting in your question but I am now concerned.

Thank you for communication. Regular medicine and life style i.e. food and exercise are very important. In my case additional stress was very important .I am personality type 'A'. Perfection being my motto I get a lot of stress every where in dealing with people. And I am sure my both attacks were as a cosequence of my stress . But stress was not immediate cause. After some years we become lax in every thing. That should not happen. I still feel that this time too I will manage with medicine alone. Wishing you will not have second attack. Take care.
