Key result
The abnormal chest radiogram cardiothoracic ratio had a sensitivity of 56.6% and an accuracy of 59.2% for diagnosing left ventricular dysfunction, indicating it is not an accurate screening method.
Why the study?
Do chest X-ray measurements (cardiothoracic ratio and frontal area) accurately diagnose left ventricular dysfunction compared to LV angiogram in patients undergoing cardiac catheterization?
Observational (n=120)
Single-blind
No
Do chest X-ray measurements (cardiothoracic ratio and frontal area) accurately diagnose left ventricular dysfunction compared to LV angiogram in patients undergoing cardiac catheterization?
Chest X-ray measurements, including cardiothoracic ratio and frontal area, have low sensitivity and accuracy for diagnosing left ventricular dysfunction and should not be relied upon as a primary screening tool.
No takes yet. Share an insight, caveat, or question.
Chest X-ray cardiothoracic ratio lacks screening accuracy for LV dysfunction; leaves open its adjunctive value in select populations or with modern modalities.
Shareef et al. (2009) conducted an observational in Left ventricular dysfunction (n=120). Chest X-Ray (Cardiothoracic ratio and Frontal Area) vs. Left ventricular angiogram was evaluated on Diagnostic accuracy (sensitivity) of abnormal cardiothoracic ratio for left ventricular dysfunction. The abnormal chest radiogram cardiothoracic ratio had a sensitivity of 56.6% and an accuracy of 59.2% for diagnosing left ventricular dysfunction, indicating it is not an accurate screening method.
