Abstract/OtherAbstract:
J Clin Hypertens (Greenwich). 2012; 14:618-622. © 2012 Wiley Periodicals, Inc. Resistant hypertension (RH) affects 8% to 30% of hypertensive patients. Blood pressure (BP) reflects the interaction between vascular compliance, resistance to flow, intravascular volume, and cardiac contractility. The relationship of RH with total arterial compliance index (TACI) has not been adequately explored. The RH period prevalence (RH at baseline or follow-up) was determined in a hypertensive cohort (N=156) and compared across quartiles of TACI. Age- and sex-adjusted systolic BP, diastolic BP, and antihypertensive therapeutic intensity score (TIS) were also determined at the time of first BP control. The cohort was 85.3% African American and 67.3% female. Median follow-up was 7 months. The prevalence of RH at baseline was 14.7% while the period prevalence was 43.6%. The period prevalence of RH by ascending quartile for TACI was 66%, 36.8%, 40%, and 30.8% (P=.008). The average BP and antihypertensive TIS at first BP control across TACI quartiles was 122.3/73.4 mm Hg (2.26), 120.7/72.5 mm Hg (1.88), 122.4/75.3 mm Hg (1.71), and 120.0/79.4 mm Hg (1.64) (P=.62, P=.03, P=.13). Low TACI was linked to higher RH prevalence and antihypertensive TIS at first attainment of goal BP according to the Joint National Committee on Prevention, Detection, Evaluation and Treatment of High Blood Pressure. TACI provides prognostic information that is clinically and perhaps pathophysiologically relevant in RH.
