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

Table 4

Cardiothoracic ratio in the studied subgroups differing in the geometry of the left ventricular.

		CTR^b	Heart silhouette enlargement (CTR >0.50)^a
Subgroups differing in left ventricular hypertrophy	NG	0.46 ± 0.02	0.0 (0)
	LVH	0.52 ± 0.04	35.8 (29)
		<0.05	<0.05
Subgroups differing in the type of left ventricular geometry	NG	0.46 ± 0.02	0.0 (0)
	CR	0.49 ± 0.02	23.4 (11)
	CH	0.53 ± 0.04	66.7 (10)
	EH	0.52 ± 0.05	42.1 (8)

^aQualitative variable expressed as a percentage (number); ^bquantitative variable expressed as mean ± standard deviation; 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.
