I recently was in ICU for four days admitted for COPD incident. After my first full blown anxiety attack while still in the ER, I was admitted. On second night in ICU I coughed all night ad my nurse noticed irregularities in the monitor which after and echocardiogram, stress and stressless testsdiagnosed with small heart attack and 35% blood output. My questions are: is Krill oil beneficial, can my heart recover? I am on Listropil, and Carvdilol, I am 62 no family heart problems
