Patient selection CIED infection
Risk factors for short-term mortality on multivariate analysis:
(1) heart failure (HR 9.3)
(2) corticosteroid therapy (HR 4)
(3) infective endocarditis as the CIED infection (HR 5.6)
Risk factors for long-term mortality on multivariate analysis:
(1) heart failure (HR 2)
(2) corticosteroid therapy (HR 2)
(3) infective endocarditis as the CIED infection (HR 1.7)
(4) age (HR 1.2 per 10 year increment, youngest patient 17 years old. If we start at age 20 then the HR for age 60 would be about 2)
(5) active malignancy (HR 1.6) vs metastatic malignancy (HR 6)
(6) acute renal failure on admission (HR 1.9)
(7) de novo implant (HR 1.9) or system revision/upgrade (HR 1.6)
X for short term mortality =
= (2.2309 if heart failure) + (1.3951 if corticosteroids) + (1.7222 if endocarditis) – 5.4439
probability of short-term mortality =
= 1 / (1 + EXP((-1) * X))
