PG - e12612 LID - 10.1111/anec.12612 [doi] LID - e12612 AB - BACKGROUND: Electrocardiography (ECG) may be an efficacious diagnostic and prognostic tool in hypertrophic cardiomyopathy (HCM). This study aimed to investigate association between deep T-wave inversion (TWI) and apical HCM, and between fragmented QRS (fQRS) complex and myocardial fibrosis in patients with HCM. METHODS: Patients with documented HCM by cardiac magnetic resonance imaging (CMR) during 2005-2015 were studied. The 12-lead ECG and CMR were performed on the same day. All patients underwent CMR for the assessment of cardiac structure, function, and late gadolinium enhancement (LGE). LGE was used to detect myocardial fibrosis. RESULTS: One hundred forty-four HCM (mean age 66 +/- 15.8 years, 60.4% male) were included. Twenty-nine (20.14%) subjects had deep TWI, and apical HCM was found in 76 (52.78%). Deep TWI was associated with apical HCM with the Odds ratio (95%CI) of 5.82 (2.07, 16.04) and p < 0.001 in univariate analysis model. The association was still significant in multivariate analysis with adjusted Odds ratio (95%CI) of 9.86 (3.17, 30.66), p < 0.001. Forty-seven (32.64%) subjects had fQRS complex, and myocardial fibrosis was detected in 101 (70.14%). fQRS complex was found to be associated with myocardial fibrosis in univariate analysis with the Odds ratio (95%CI) = 2.75 (1.16, 6.54), p = 0.019. However, the association cannot be demonstrated in the multivariate analysis. CONCLUSION: Deep TWI is independently associated with apical HCM, but the relationship between fQRS complex and myocardial fibrosis did not survive multivariate analysis.
