Templer's death anxiety scale on the relationship between white coat hypertension and anxiety: A cross-sectional study.

The relationship between white coat hypertension (WCH) and anxiety remains not fully elucidated. This study aims to investigate the correlation between WCH and Templer's Death Anxiety Scale (T-DAS) questionnaire. Asymptomatic individuals with a familial history of sudden cardiac death or acute myocardial infarction within the last year, who presented at our cardiology outpatient clinic, were enrolled in this prospective, single-center, cross-sectional study. Among those with elevated blood pressure in the outpatient clinic setting, participants were categorized into normotensive and WCH groups through 24-hour ambulatory blood pressure monitoring. Demographic features, laboratory parameters, and T-DAS scores were documented. Logistic regression and sensitivity analyses were conducted to ascertain WCH occurrence. Among 324 consecutive participants, 90 were diagnosed with WCH. T-DAS scores were significantly elevated in the WCH subgroup, particularly among those seeking early medical attention following bereavement. Multivariable logistic regression highlighted gender, BMI, heart rate, T-DAS, and admission time as independent correlates of WCH. Significantly, T-DAS exhibited the third most substantial contribution to the regression analysis, following admission time and heart rate. The multivariable logistic regression analysis incorporating T-DAS exhibited high robustness, discrimination, fit, and calibration, with a Brier score of 0.106, adjusted R2 of 0.576, and C-statistic of 0.905 (95% CI: 0.871-0.940, p < 0.001). T-DAS, with a threshold of >8, demonstrated 48% sensitivity and 90% specificity in detecting WCH. Additionally, decision curve analysis verified that the model including T-DAS offers a net benefit in detecting WCH. This study unveils a potential association between WCH and death anxiety.
