Park LP et al. Validated risk score for predicting 6-month mortality in infective endocarditis. J Am Heart Assoc. DOI: 10.1161/JAHA.115.003016. PMID: 27091179. Table 5 weights: constant 4; age 45 or younger 0, 46–60 2, 61–70 3, older than 70 4; dialysis 3; nosocomial IE 2; prosthetic IE 1; symptoms for more than 1 month before admission −1; Staphylococcus aureus 1; viridans group streptococci −2; aortic vegetation 1; mitral vegetation 1; NYHA class 3 or 4 heart failure 3; stroke 2; paravalvular complication 2; persistent bacteremia 2; surgical treatment −2. The cohort scores fell in 0–22 and were grouped as 0–6, 7–8, 9–10, 11–16, and 17–22. The arithmetic sum of the printed weights can be −1 through 26, and those ends stay in the outer groups. (2016)
