I'm 54 and had raised b/p, palpatations, chest pain/cramp and shortness of breath since christmas. Went to GP to have b/p checked 180/110 and ECG, GP stated my heart beat was irregular, she done ECG which indicated old MIwas sent to hospital. At hospital troponin level 0.12 then 0.6, echo gram showed wall damage with 45 % EF they told me I had MI previous 10-14 days. Sent to another hospital for angiogram which showed everything normal and not had MI, yet they discharged me with a statin, beta blocker & GNT spry. What is happening
