| Abstract |
Echocardiography is not recommended for routine pre-surgical evaluation but may have value for patients at high risk of major adverse cardiovascular events (MACE). The objective of this study was to evaluate whether pre-operative echocardiography is associated with lower risk of post-operative MACE among patients with coronary artery disease. Using administrative and registry data, we examined associations of echocardiography within 3 months prior to surgery with postoperative MACE (myocardial infarction, revascularization, or death within 30 days) among patients with coronary artery disease undergoing elective, non-cardiac surgeries in the United States Veterans Affairs healthcare system in 2000-2012. Echocardiography preceded 4,378 (16.4 %) of 26,641 surgeries. MACE occurred within 30 days following 944 (3.5 %) surgeries. A 10 % higher case-mix adjusted rate of pre-operative echocardiography assessed at the hospital level was associated with a hospital-level risk of MACE that was 1.0 % (95 % confidence interval [CI] 0.1 %, 2.0 %) higher overall and 1.7 % (95 % CI 0.2 %, 3.2 %) higher among patients with recent myocardial infarction, valvular heart disease, or heart failure. At the patient level, pre-operative echocardiography was associated with an odds ratio for MACE of 1.9 (95 % CI 1.7, 2.2) overall and 1.8 (95 % CI 1.5, 2.2) among patients with recent myocardial infarction, valvular heart disease, or heart failure adjusting for MACE risk factors. Pre-operative echocardiography was not associated with lower risk of post-operative MACE, even in a high risk population. Future guidelines should encourage pre-operative echocardiography only in specific patients with cardiovascular disease among whom findings can be translated into effective changes in care. |

Attention Score in Context
This research output has an Altmetric Attention Score of 2. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 12 September 2016.
All research outputs
#14,209,240
of 22,886,568 outputs
Outputs from BMC Cardiovascular Disorders
#659
of 1,620 outputs
Outputs of similar age
#192,540
of 335,711 outputs
Outputs of similar age from BMC Cardiovascular Disorders
#9
of 21 outputs
Altmetric has tracked 22,886,568 research outputs across all sources so far. This one is in the 37th percentile – i.e., 37% of other outputs scored the same or lower than it.
So far Altmetric has tracked 1,620 research outputs from this source. They receive a mean Attention Score of 3.9. This one has gotten more attention than average, scoring higher than 58% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 335,711 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 42nd percentile – i.e., 42% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 21 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 57% of its contemporaries.
