Purpose
The aim of this study was to assess the prevalence of reportable cardiac findings
detected on abdominopelvic CTs and the association with subsequent cardiovascular
events.
Materials and Methods
We performed a retrospective search of electronic medical record of patients who underwent
abdominopelvic CT between November 2006 and November 2011 with a clinical history
of upper abdominal pain. A radiologist blinded to the original CT report reviewed
all 222 cases for the presence of pertinent reportable cardiac findings. The original
CT report was also evaluated for documentation of pertinent reportable cardiac findings.
The following findings were recorded on all CTs: presence of coronary calcification,
fatty metaplasia, ventricle wall thinning and thickening, valve calcification or prosthesis,
heart/chamber enlargement, aneurysm, mass, thrombus, device, air within ventricles,
abnormal pericardium, prior sternotomy, and adhesions if prior sternotomy. Medical
records were reviewed to identify cardiovascular events on follow-up in patients with
the presence or absence of cardiac findings. We compared the distribution findings
in patients with and without cardiac events using the Wilcoxon test (for continuous
variables) and the Pearson's chi-squared test (for categorical variables).
Results
Eighty-five of 222 (38.3%) patients (52.7% females, median age 52.5 years) had at
least one pertinent reportable cardiac finding on the abdominopelvic CT, with a total
of 140 findings in this group. From the total 140 findings, 100 (71.4%) were not reported.
The most common findings seen on abdominal CTs were: coronary artery calcification
(66 patients), heart or chamber enlargement (25), valve abnormality (19), sternotomy
and surgery signs (9), LV wall thickening (7), device (5), LV wall thinning (2), pericardial
effusion (5), and others (3). After a mean follow-up of 43.9 months, 19 cardiovascular
events were found in the cohort (transient ischemic attack, cerebrovascular accident,
myocardial infarction, cardiac arrest, acute arrhythmia, palpitation, syncope and
acute chest pain). Only 1 event occurred in the group of patients with no incidental
pertinent reportable cardiac findings (1/137 = 0.73%). All other 18 events occurred
in patients with incidental pertinent reportable cardiac findings (18/85 = 21.2%),
which was significantly different (p < 0.0001). One out of the total 19 events in the overall group (5.24%) occurred in
a patient with no incidental pertinent reportable cardiac findings while 18 of 19
total events (94.74%) occurred with patients with incidental pertinent reportable
cardiac findings, which was also significantly different (p < 0.001). Fifteen of the total events (79%) occurred in patients in whom the incidental
pertinent reportable cardiac findings were not reported, which was significantly different
(p < 0.001) from the four events that occurred in patients in whom the incidental pertinent
reportable cardiac findings were reported or had no findings.
Conclusions
Incidental pertinent reportable cardiac findings are common on abdominal CTs and are
frequently not reported by radiologists. These findings are of clinical relevance
since patients with pertinent reportable cardiac findings have a significantly higher
incidence of cardiovascular events on follow-up.
