The Prognostic Value of High-Sensitive Troponin I in Stable Coronary Artery Disease Depends on Age and Other Clinical Variables (original) (raw)
To study the prognostic value of high-sensitive troponin (hs-cTn) I in stable coronary artery disease. In total, we studied 705 patients. Secondary outcomes were the incidence of: (1) acute ischemic events and (2) heart failure or death. The primary outcome was the composite of them. Patients with hs-cTnI >0 ng/ml (62.1%) were older, had a lower estimated glomerular filtration rate, more frequent a history of hypertension, atrial fibrillation, ejection fraction <40%, and therapy with angiotensin-converting enzyme inhibitors, diuretics and acenocumarol. The follow-up period was 2.2 ± 0.99 years. Fifty-three patients suffered an acute ischemic event, 33 died or suffered heart failure and 78 developed the primary outcome. By univariate Cox's regression analysis, hs-cTnI >0 was associated with a higher risk of developing the primary outcome [relative risk = 2.360 (1.359-4.099); p = 0.001] and heart failure or death [relative risk = 5.932 (1.806-19.482); p < 0.001], but n...
