My brother aged 39 years old had severe chest pain and prespiration and he is admitted in the hospital two days back and they diagonised that blood get clotted in the heart vein because of thickness of blood and blood is not flowing smoothly. Doctors could able to remove the glot and they told he can be discharged and again yesterday the same thing repeated and they gave one injection to make the blood thin. His heamoglobin is more than 19 and Doctors say that this is one of the reason to increase the thickness of blood. What would be the reason for such blood glotting in heart vein. He is also unable to breath and oxygen mask has been get for breathing. Please send your considered opinion for the same and also remedy to be followed. YYYY@YYYY
