Nýjum starfskröftum var kennd endur-
lífgunaraðgerð við komu á deildina, og
gengu þær yfirleitt allvel, þótt árangur
væri ekki meiri en raun ber vitni.17
Að vonum var lyfjameðferð gegn hjart-
sláttaróreglu algengari á þessu tímabili,
en því, sem á undan fór, enda tók áhugi
manna á fyrirbyggjandi meðferð mjög að
aukast um þetta leyti.17 Eins og áður var
segavörnum alltaf beitt, nema sérstök rök
mæltu gegn því.
Ekki þykir ástæða til að fjölyrða um
hina einstöku áhættuþætti sbr. fyrri rann-
sókn.17 Hvað reykingar snertir, voru nið-
urstöður mjög á sama veg og fyrr, þ. e. a. s.
dánartala reykingamanna var lægri og
meðalaldur þeirra sömuleiðis. Um túlkun
á þessum atriðum vísast enn í fyrri grein
okkar og bent er á erlendar niðurstöður
varðandi þessi atriði.2 3 6 10 17

Dánartala er svipuð fyrst eftir og fyrir
opnun hjartagæzludeildar Landspítalans.
Eftir stofnun deildarinnar koma sjúkling-
ar fyrr inn til meðferðar. Lyfjameðferð
gegn hjartsláttaróreglu er meiri en áður.
Hjartadá er sjaldgæfara en fyrr.

ENGLISH SUMMARY
A Coronary Care Unit was started in 1969
at the University Hospital of Iceland, Reykja-
vik. When reviewing the mortality and com-
plications of myocardial infarction before and
after that year we have defined the interval
between 1/1 1969 and 1/4 1970 as a transitional
period during which some of the characteristics
of the usual CCUs had been adopted but others
not.
Results from the pre-CCU period have al-
ready been published. During the transitional
period 94 patients with symptoms, biochemical
and electrocardiographic findings satisfying the
WHO criteria for the diagnosis of myocardial
infarction were admitted, 22 females and 72
males. The overall mortality was 23,4% which
is similar to the pre-CCU period (21%). The
lower mortality which was expeeted with the
advent of increased safety and prophylactic
measures was possibly nullified by the fact
that the patients were admitted earlier after
the onset of acute symptoms, 55,2% in the
first 6 hours as compared with 46% in the
pre-CCU period, and the slightly higher in-
cidence of previous infarcts,
The majority of the patients were given
anticoagulants and 40 received some antiar-
rythmic agents.
