Discerning the relationship between left ventricular geometry, high-sensitivity troponin T, and nondipper hypertension.
Blood Pressure Monitoring 2018 Februrary
INTRODUCTION: Hypertension can cause anatomic changes in the left ventricle, generally leading to abnormal geometry. High-sensitivity cardiac troponin T (hs-cTnT) values have been shown to be positively correlated with left ventricular hypertrophy in hypertensive patients. The current study investigated the diagnostic value of hs-cTnT in patient with nondipper hypertension (NDH) as well as determined the correlation between left ventricular geometric patterns and hs-cTnT values in hypertensive patients.
PATIENTS AND METHODS: A total of 100 consecutive patients (58 women and 42 men) who were referred to our clinic between 1 October 2015 and 1 March 2016 with elevated blood pressure (BP) were included. Of the patients, 63 had dipper hypertension [nocturnal decline in mean BP (≥10%)], whereas the remaining 37 had NDH [nocturnal decline in mean BP (<10%)]. Of note, hs-cTnT levels were measured only once during admission. Echocardiographic examinations were performed at baseline month and repeated at the sixth month.
RESULTS: Hs-cTnT was significantly increased in those with NDH (P<0.001). The NDH group experienced significant decreases in concentric hypertrophy pattern over 6 months (P=0.014). Hs-cTnT was significantly related with nondipping status (r=0.747, P<0.001). Hs-cTnT was also an independent predictor of NDH (odds ratio=1.034, 95% confidence interval: 1.018-1049, P<0.001). Hs-cTnT value of more than 0.95 ng/l predicted NDH with a sensitivity of 75% and specificity of 98% (area under the curve: 0.86; 95% confidence interval: 0.782-0.925; P<0.001).
CONCLUSION: Our current results indicate that patients with NDH had higher hs-cTnT levels than the patients with dipper hypertension. Hs-cTnT was an independent predictor of NDH and was significantly related with nondipping status. Hence, hs-cTnT may be used as diagnostic biomarker in NDH.
