Object.ve: t.e object.ve of t.is st.dy was t. analyse t.e reversibilit. of t.e ant.coagulant.effect.of warfarin by comparing prot.rombin complex concent.at. (PCC) versus frozen fresh plasma (FFP) in cardiology pat.ent. wit. serious warfarin int.xicat.on. Met.ods: t.is was an observat.onal and ret.ospect.ve st.dy comprising 67 pat.ent. (18 in group I [PCC] and 49 in group II [FFP]). t.e primary endpoint.was t.e reversal of ant.coagulant.effect.of warfarin aft.r 2 and 24 hours of PCC or FFP administ.at.on. Comparisons bet.een t.e groups were made using t.t.st.and Q-square. Mult.variat. analyses were conduct.d using logist.c regression, and t.e result. were considered significant.when p Result.: t.e medium dose used was 27.6 UI/kg of PCC and 14.5 ml/kg of FFP. Significant.differences were observed bet.een groups I and II in t.e INR reversibilit. measurement. aft.r 2 hours (33.3% vs. 6.1%, p = 0.001) and 24 hours (38.9% vs. 12.2%, p = 0.009) as well as in t.e occurrence of pulmonary edema (5.6% vs. 42.9%, OR = 11.10, p = 0.04). t.e AUC for PCC was 0.891 (CI 95% [0.72 - 1.0]), and for FFP, it.was 0.291 (CI 95% [0.09 - 0.49]). Conclusions: PCC is bet.er t.an FFP t.eat.ent.in reversing t.e warfarin int.xicat.on aft.r 2 and 24 hours of administ.at.on. Furt.ermore, PCC showed lower pulmonary edema in cardiology pat.ent..

Purpose: t. compare t.e demographic dat. and out.omes of younger versus elderly pat.ent. wit. acut. coronary syndromes. Met.ods: t.is was a ret.ospect.ve dat. bank analysis st.dy wit. 966 pat.ent. (268 in t.e younger group (less t.an 55 years) and 698 in t.e elderly group (more t.an 55 years)). Dat. were obt.ined about.clinical charact.rist.cs, angiography, and medicat.on used at.hospit.l and coronary definit.ve t.eat.ent. t.e primary endpoint.was all cause of in-hospit.l deat. and combined event.. Comparison bet.een groups was made by Anova and Q-square. Mult.variat.ve analysis was det.rmined by logist.c regression and was considered significat.ve when p t.rm mort.lit. and combined event. were st.died using Kaplan- Meyer curves wit. median follow-up of 11.21 mont.s. Result.: t.e median age in t.e younger group was 48 years versus 69 years in t.e elderly group. In t.e younger group 26% was St.myocardial infarct.on versus 18% in t.e elderly group. About.7% of younger pat.ent. were submit.ed t. coronary bypass surgery and 42% t. percut.neous coronary angioplast. versus 12% and 25% in elderly group, respect.vely. Significant.difference was observed bet.een t.e younger versus elderly groups in deat.s (1.5% × 7.5%, p = 0.004), combined event. (14.9% × 26.3%, p = 0.02) and killip III/IV (3.7% × 8.3%, p = 0.04). Long-t.rm mort.lit. was 3.7% × 10.2%, p = 0.01). Conclusions: In pat.ent. wit. acut. coronary syndromes age was an import.nt.predict.r fact.r of mort.lit. and complicat.ons. Significat.ve differences in out.omes were observed bet.een t.e t.o groups in-hospit.l and long-t.rm follow-up.
