In total 109 patients (40 patients with isolated systolic hypertension) were included in our analysis. After 3?months, blood pressure reduction was more pronounced among patients with combined hypertension compared with patients with isolated systolic hypertension (systolic 24\hour average 9.310.5 versus 5.011.5?mm?Hg, test. Between\group differences were compared using a 2\tailed independent samples t test for continuous data or univariate ANOVA with post hoc\testing, as appropriate. The 2 2 test was used for categorical variables. Because the tertiles of iPWV were not perfectly balanced, an additional age\adjusted regression model was calculated for the average drop in daytime BP at 3?months. In addition, a stepwise\forward logistic regression analysis for BP response at 3?months was calculated using previously described predictors for a successful RDN (office pulse pressure, presence of ISH, use of vasodilators and aldosterone antagonists as well as iPWV).1, 9 All statistics were calculated using SPSS 19.0.0.2 (IBM Corp). Results In total, 131 consecutive patients underwent RDN and invasive measurement of iPWV and iPP at our center. Of these, 109 patients were on stable medication at 3\month follow\up and were included in analyses. Patients with ISH were split into 3 groups according to iPWV tertiles. Baseline Characteristics At baseline, patients with combined hypertension (CH) were younger than patients with ISH (Table?1) and had higher systolic and diastolic BP on ABPM average (Table?2). Comorbidities were balanced between the groups, with no significant differences in prevalence of diabetes mellitus or cardiovascular diseases. The mean number of prescribed antihypertensive drug classes was not different between the groups (CH versus ISH 5.01.6 versus 4.81.3), and drug classes did not differ significantly between the groups apart from renin antagonists, which were prescribed more frequently among patients with CH with small absolute numbers (Table?3).
