Abstract
Objective
To evaluate the patency of individual and sequential coronary artery bypass
in patients with ischemic heart disease.
Methods
We searched PubMed, Cochrane Library, Excerpta Medica Database, and
ClinicalTrials.gov databases for controlled trials. Endpoints included graft
patency, anastomosis patency, occluded rates in left anterior descending
(LAD) system and right coronary artery (RCA) system, in-hospital mortality,
and follow-up mortality. Pooled risk ratios (RRs) and standardized mean
difference (SMD) were used to assess the relative data.
Results
Nine cohorts, including 7100 patients and 1440 grafts under individual or
sequential coronary artery bypass. There were no significant differences
between individual and sequential coronary artery bypass in the graft
patency (RR=0.96; 95% CI=0.91-1.02; P=0.16;
I2=87%), anastomosis patency (RR=0.95; 95%
CI=0.91-1.00; P=0.05; I2=70%),
occluded rate in LAD system (RR=1.03; 95% CI=0.92-1.16;
P=0.58; I2=37%), occluded rate
in RCA system (RR=1.36; 95% CI=0.72-2.57; P=0.35;
I2=95%), in-hospital mortality (RR=1.57; 95%
CI=0.92-2.69; P=0.10; I2=0%),
and follow-up mortality (RR=0.96; 95% CI=0.36-2.53; P=0.93;
I2=0%).
Conclusion
No significant differences on clinical data were observed regarding
anastomosis patency, occluded rate in LAD system, occluded rate in RCA
system, in-hospital mortality, and follow-up mortality, indicating that the
patency of individual and the patency of sequential coronary artery bypass
are similar to each other.
