Abstract:
BACKGROUND: Left ventricular hypertrophy (LVH) offers prognostic information beyond that provided by the evaluation of traditional cardiovascular risk factors. However, the validation of electrocardiogram (ECG) criteria for the diagnosis of LVH is limited in Korea general population. The purpose of this study is to investigate the diagnostic accuracy of ECG criteria for the detection of LVH in general population. METHODS: In the present study, we investigated a total of 1,946 adults from the community-based cohort. The left ventricular mass index (LVMI) was estimated with echocardiographic measurement and adjusted with body surface area. LVH was defined as a value greater than or equal to the sex-specific 90th percentile value of LVMI. ECG criteria for the diagnosis of LVH were Sokolow-Lyon criteria and Cornell criteria. RESULTS: The LVMI was significantly higher in male subjects (91.1 +/- 23.9 g/m2 vs. 83.9 +/- 21.7 g/m2, p < 0.001). The cutoff values were 120.8 g/m2 in male subjects and 112.2 g/m2 in female subjects. The sensitivity and specificity of Sokolow-Lyon criteria were 5.6% and 93.6% in male, 4.1% and 97.8% in female. Those of Cornell criteria were 2.8% and 98.7% in male, 14.3% and 95.8% in female. In male, the area under the receiver operating characteristic curves of Sokolow-Lyon voltage and Cornell voltage were 0.55 and 0.52. And those in female were 0.59 and 0.60. CONCLUSIONS: In our community-based sample, ECG criteria showed low sensitivity and high specificity. The performance of ECG criteria for detection of LVH was suboptimal, suggesting limited usefulness of ECG as mass screening tools.
