Late outcomes
A total of 52 deaths (early or late) were observed over a median (IQR)
follow-up period of 6.01 (3.56, 9.47) years. The overall 1-, 5- and
10-year survival was 73.6%, 53.4% and 32.1% respectively (Figure 2).
The prespecified factors assessed for an unadjusted association with
overall survival are presented in Table 4. Only older age was
univariably associated with increased risk of mortality (per 10-year
increase: HR 1.55, 95% CI 1.18-2.02; p=0.002). There was no association
between ejection fraction, coronary artery disease, previous cardiac
surgery, concomitant surgical procedures, or pre-operative renal failure
with mortality. There was no survival advantage of performing a radical
resection in this population (HR 1.35, 95% CI 0.77-2.36, p=0.295).
There was also no difference in survival between patients that underwent
pericardiectomy with concomitant cardiac procedures and patients that
underwent isolated pericardiectomy (HR 0.70, 95% CI 0.39-1.27,
p=0.246).
