Hello koen;
welcome to HealthcareMagic
The working of heart is considered as the capacity to pump the blood to the body and is calculated as Ejection fraction of the Left Ventricle(as it is responsible to supply blood to the other parts of body.The ejection fraction can reduce due to diseases like cardiomyopathy;myocardial infacrt(heart attack);as a result of some specific viral infections;infective endocarditis.etc.If the ejection fraction is around or above 60% then you are fine and can do any sort of work but if it reduces below 40% then the person cannot work upto full capacity like he will become breathless while climbing stairs easily;cannot walk long distance due to weak heart muscles.So if the heart is working 35% then it is becoming weak and the person will get easily tired and breathless even after doing work which otherwise would have been easy for him.
Thanks

I am talking from experience. Having a ejection fraction (Medical term is E.F. rate ) below 35% is not good news for a person. It is a sign of a weakening heart muscle. My E.F. rate got down to 20 % with my cardiomypathy (Enlarged heart muscle). Since my heart muscle weakened rather rapidly I was a candidate for a heart transplant. The transplant was performed last June of 2006 and my E.F. rate is at 60 % now. This new E.F. rate is considered normal. The only drawback is I am on immuno-suppressant drugs for the rest of my life to prevent rejection of my new heart.

Hello Dr, 41 year old, non-smoker, 1-5 units of alcohol a week, active, no other health issues. Family history of heart problems (Hypertrophic cardiomyopathy ), have been checked and do not have it, although have a slight thickening of arterial knuckle which gets monitored. I m getting what feels like pulses or faint flutters from my oesophagus region to the top of my sternum region, these symptoms are infrequent during the day to sometimes non-existent, but at night the symptoms only occur when laid on my back or on my left side (they disappear when I m lying on my right side?) and feel more constant with a heart beat ie pulses at a constant rate. Occasionally have slight breathlessness since this has started 1 week ago. Now I ve had a slight upset stomach (although not constipated I ve not been regular) the last week and the symptoms do seem to be more present when I have heavy feeling in my stomach and then subside once I pass wind. Is the pulses/flutter linked to this and could be a blockage and wind not escaping? Or something else?

My husband's heart is beating loudly and seems to be beating irregularly. I took his blood pressure and it was normal. His heart rate was 102bpm. He also has an urge to cough periodically. He's had these episodes happen before and the cough has helped at times. Do we need to be concerned? His father died from heart disease and started having an irregular heart beat when he was 35.
