Example sentences for: echocardiograms

How can you use “echocardiograms” in a sentence? Here are some example sentences to help you improve your vocabulary:

  • The only studies to perform repeated echocardiograms (separated by one year in both) in large numbers of unexposed persons found either no net progression or net regression in their control groups [ 24 25 ] . Because these studies did not report usable direct measures of incidence, we made several assumptions to estimate unexposed incidence using raw data from the Framingham study and from the studies reviewed here.

  • While two studies performed echocardiograms one year apart in sizable populations, both showed either no net progression or a net decrease in regurgitation in the unexposed, control groups [ 24 25 ] . These findings underscore the infrequency of new onset, FDA-positive AR or MR in the unexposed population.

  • These include measurement bias (related to acquisition and reading of echocardiograms) [ 22 ] , selection bias (particularly in studies with incomplete follow-up) [ 31 ] , and potential reversibility of valvulopathy [ 10 24 25 32 ] . If a reversible component occurred rather quickly after stopping drugs, then one might expect a stable, lower prevalence in studies performed well after drugs were stopped, with no relationship between prevalence of valve dysfunction and time off medication.

  • A single study among those reviewed in our meta-analysis excluded persons with valve disease using echocardiograms taken prior to starting drug [ 11 ] . That study yielded estimates of AR and MR incidence that were similar to our summary estimates, further supporting our findings.

  • Two-thirds of ejection fractions were obtained by echocardiograms, though catheterizations accounted for a larger percentage of results in the doxazosin group than in the chlorthalidone group (36% vs. 24%).
