“…Using TTR 70% as cut-off in our cohort of patients with MHV, inferior TTR corresponded to both a doubled rate of bleedings and death and a 50% higher rate of thromboembolic events. The current results support and extend the results from a previous study from our group where TTR influenced the risk of bleedings and death, but not thromboembolic events, in patients with MHV 8. One way to increase TTR is using a computer-aided warfarin dosing system 21 22.…”

“…In contrast, there are little data available about the importance of warfarin treatment quality in patients with MHV. The reports indicate that the quality also influences outcome in this patient population but the studies have so far included limited study populations and follow-up times 7 8…”

“…Previous studies have suggested that achieving stable anticoagulation requires a number of weeks to months of treatment, with the INR maintained within the effective range in only 40-60% of patients, including those with a stable status (9,10). Risk of bleeding or rethrombosis is increased during the remaining non-therapeutic-target-achieving (TTA) period, particularly in the initial treatment period (11)(12)(13). Therefore, rapidly achieving therapeutic INR may decrease the incidence of adverse reactions, ensure anticoagulation efficacy and reduce the duration and expense associated with heparin treatment.…”

“…Число операций по протезированию увеличивается в среднем на 5-7 % в год (биологическими протеза-ми -на 8-11 %, механическими -на 3-5 %) [30]. Например, в Швеции ежегодно проводят около 2500 операций на клапанах сердца, при этом 75 % случаев приходится на протезирование аортального клапана; в 70 % случаев вмешательств на митральном клапане выполняют митральную вальвулопластику, а в осталь-ных -протезирование преимущественно (60 %) био-логическим протезом [31]. Общий объем хирургиче-ской помощи больным с ППС в России с 1996 по 2008 г. увеличился в 2,2 раза: число клапаносохра-няющих операций возросло на 492 %, общее коли-чество имплантированных протезов увеличилось на 29,5 % [32].…”

“…Многие осложнения, скорее всего, возникают в связи с достижением только субоптималь-ной гипокоагуляции. В исследованиях показано, что не-обходимый уровень МНО у пациентов, получающих терапию антагонистами витамина К (АВК), достигался лишь в 60-70 % случаев [31].…”
