The study seems to touch upon major factors of increasing risk of deaths in patients with heart failure including risk factors of ischemic heart disease, reduced ejection fraction, elevated filling pressure by echo criteria and radiological evidence of pulmonary edema, however the study was not powered to look at the impact of all these factors in the small size sample of patients recruited, making it very difficult to compare its utility in addition to Hs-cTns. Here, CTNS is linked to heart failure.
