Disposisjon
• Hjerte/karsykdom- Status i dag
• Tiden etter treningsintervensjon- nytter det?
• Kronotrop insuffisiens og intervalltrening
• Oksygenopptak som en prediktor for langtidsoverlevelse etter
hjertetransplantasjon
• Overlevelsesstatistikk- Resultater fra Norge

Status 2015
• Dødelighet av hjerte/kar sykdom er stadig synkende
• Økende andel hjertesvikt pasienter
• Forebygging og behandling er fremdeles viktig!

Tiden etter
treningsintervensjon

Langtidsoppfølging
• 2 Meta analyser – tiden etter hjertesviktrehabilitering
• Minimalt som er gjort etter høy intensitetstrening (HIT)
• 41 HTx pasienter har vært til 5 års follow- up etter HIT
– TEX studien (Kari Nytrøen)

Tilbakemeldinger- TEX 5 år
• Bidra til ny kunnskap
• Gøy
• Kjempetøft
• ”Kjøpte meg tredemølle”
• Mulig å delta på gruppe

som prediktorer for langtidsoverlevelse
etter hjertetransplantasjon

Hva påvirker langtidsoverlevelse etter HTx?
•Årsak til hjertesvikt
•Donors alder
•Mottakers alder
•Iskemitid
•Utvikling av vaskulopati i koronarkar (CAV/ graftsklerose)
•Mekanisk støtte på venteliste
•VO2peak??

Forklaringsmodell med VO2peak og PF-score
•Andre variabler som forklarer overlevelse ytterligere
•Vurdert potensielle confoundere
– Påvirker både VO2peak/PF-score og overlevelse
– tommelfingel regel- endrer estimatet med 10 %

Overlevelseskurver
•VO2peak og selvrapportert fysisk helse utpeker seg som viktige prediktorer på langtidsoverlevelse.
•Fysisk kapasitet bør måles oftere, også etter hjertetransplantasjon.
