Sydney (IANS): Better management practices have improved survival
rates of heart attack victims, according to a study based on nearly 4,500
Researchers followed the outcomes for 12 years of 4,451 patients
hospitalised during 1984-87, 1988-90 and 1991-93. Changes in the management
of these patients probably continuously cut down mortality from coronary
The study was co-authored by research fellow Tom Briffa of The University of
Western Australia's (UWA) School of Population Health.
The use of proven medical treatment, such as B-blockers and
revascularisation surgery within 12 months of hospital admission accounted
for the greatest improvement of survival over 12 years, the authors claimed.
Only patients who survived 28 days after a heart attack were included in the
long-term, Perth-based study. Participants were aged from 35 to 64. Overall,
18 percent were women, 10 percent had a history of diabetes, 51 percent were
current smokers, and 40 percent had a history of high blood pressure,
according to an UWA release.
"Improvements in long-term survival are probably attributable to a
combination of various treatments rather than any single treatment. Changes
in lifestyle characteristics and dietary practices might also have
contributed to trends in survival," said Briffa.
