I am 73, I underwent bypass surgery in May 2014, my dad & mum died of heart attacks at age 53 and 69 respectively. At present there is mild decrease in GFR and mild iron deficiency, BP normal, rest all tests are OK done on 15.4.17 thru Lybrate. I now take Zyloric 100 and Dexorange, besides ecosprin 75, Prolomet 25, Rosuvas 10 regularly I feel tired, paunchy, acidous & gaseous. My main question? I am told by my heart surgeon that my genetic heart risk is about 30%. Rest nothing to worry about. I have read that the gene can attack any moment. Is it true and how can I resist it. Pls reply. Txs.
