Why the study?
Does the cardiothoracic ratio on admission chest radiography accurately detect left or right ventricular systolic dysfunction in inpatients?
Does the cardiothoracic ratio on admission chest radiography accurately detect left or right ventricular systolic dysfunction in inpatients?
The cardiothoracic ratio on admission chest radiography has limited diagnostic value for detecting moderate to severe ventricular systolic dysfunction in inpatients, suggesting historical absolute values may be unreliable.
No takes yet. Share an insight, caveat, or question.
Cardiothoracic ratio >0.55 on PA films shows limited accuracy for ventricular dysfunction; leaves open any incremental value in inpatient assessment.
Chana et al. (2015) studied this question.
