Early Diagnosis of Abnormal Left Ventricular Systolic Functions of Rare Pathogenic Titin Mutation Gene Carriers in FHCM by Three-Dimensional Speckle Tracking Echocardiography Combined with Gene Detection

Table 3

Comparison of overall three-dimensional strain indexes between the two groups ( ± s).

Index	Noncarrier group (n = 12)	Carrier group (n = 4)
GLS (%)	−24.28 ± 2.99	−20.11 ± 2.23	0.024
GCS (%)	−36.05 ± 3.98	−39.86 ± 7.76	0.211
GRS (%)	46.94 ± 5.61	53.02 ± 9.92	0.307

Compared with the noncarrier group,  < 0.05. GLS: global longitudinal strain, GCS: global circumference strain, and GRS: global radial strain.
