Cardiology Questions Answered by Verified Cardiologists.
did he test your heart?
do you take any meds?
are you overweight?
Okay. An easy way to be sure is with a BNP blood test. This is a very good marker of heart failure. Just ask for this. If this is normal then it is likely the weight that is causing this combined with veins not working great in the legs.
Also, heat makes it worse because heat causes dilation of blood vessels. This then leaks fluid into the tissues in the legs.
I recommend weight loss, low salt, compression socks and leg elevation if the BNP is normal
No that is a CMP or BMP.
YOu need a heart specific BNP

I disagree with Dr phil opinion, If you have swelling of the feet then first things to know is it present in both legs ? does it forms a pit when pressed ? If yes then you need to rule out 4 important possibilities.. these are 1..heart failure. 2... nephrotic syndrome.3.... malabsorption and varicose veins. Stepwise approach includes blood test for protein levels, urine for protein leakage, echocardiogram and doppler scan of the legs. With help of these test we can make sure of accurate cause. BNP levels which Dr phil have mentioned has less value in overweight and it has only negative predictive value, which means if this is positive then you cannot say it is due to heart failure and still you need to go for echocardiogram. So BNP levels have limitation in this case and should not be used as first test.
I hope this answers your question. Let me know if you need more assistance.
While on other hand if swelling is on one leg only then we need to rule out clot, infection and inflammation in that leg. Also if the edema does not forms a pit when pressed then it can be due to blockage of the lymphatic ducts.
This is an extreme workup for a simple problem.
