Hello Thanks for posting at HCM. I have gone through your description. It is very early after a stent placement to get angina symptoms. This occurs only when body does not accept the stent. However the symptoms may be more pronounced in that case. Since you have said that you have suffered from a heart attack, your heart pumping function must have dropped. This may be cause of edema or swelling on the hands. But this edema also tends to accumulate more on the legs. Do have leg swelling also? Protein deficiency can also cause swelling or edema of hands. Please get your serum proteins checked. The headache can be due to some medications that are given to keep the arteries of the heart dilated. These medications also cause dilation of blood vessels in the head thereby causing headache. As of now there is nothing to worry. Get your serum proteins checked. Still if you feel very insecure and want to rule out whether its a stent problem you an do a treadmill test by naughton s protocol. It is a test in which you will be made to walk on a treadmill while your ECG is continuously being monitored. This will help you to ascertain whether the stent is causing problems. But according to me, its patent and should not be a matter of concern. Wishing you good health. Regards
