Radiological Cardiothoracic Ratio as a Potential Marker of Left Ventricular Hypertrophy Assessed by Echocardiography

Table 3

Geometry of the left ventricular in the studied subgroups differing in cardiothoracic ratio.

	Enlarged heart silhouette (CTR > 0.50)	Nonenlarged heart silhouette (CTR ≤ 0.50)
NG^a	0.0 (0)	22.4 (15)	<0.05
LVH^a	100.0 (29)	77.6 (52)	<0.05
CR^a	37.9 (11)	53.7 (36)	ns
CH^a	34.5 (10)	7.5 (5)	<0.05
EH^a	27.6 (8)	16.4 (11)	ns

^aQualitative variable expressed as a percentage (number); CH: concentric hypertrophy of the left ventricular; CR: concentric remodeling of the left ventricular; CTR: cardiothoracic ratio; EH: eccentric hypertrophy of the left ventricular; LVH: left ventricular hypertrophy; NG: normal geometry of the left ventricular.
