Abstract Introduction Identification of non-adherence to antihypertensive drugs is crucial to improve resistant hypertension (RH). For this therapeutic drug monitoring is the most reliable method. Purpose The primary objective of this analysis is to determine whether drug levels measured with a dried blood spot (DBS) method combined with personalized feedback leads to a decrease in prevalence of RH after 3 months due to an increase in adherence. Methods This is a multi-centre single-blinded randomized controlled trial (RHYME-RCT, NL6736). Patients went to an eligibility visit, where DBS sampling and a 24-hour ambulatory blood pressure measurement (ABPM) was performed simultaneously. Patients with a daytime systolic blood pressure (SBP) >135 and/or diastolic blood pressure (DBP) >85 mmHg were randomized to standard treatment (control) or intervention. The intervention was performed by the treating physician and included information on drug levels and a personalized feedback conversation based on a feedback tool. The follow-up period was one year and included visits at 3, 6 and 12 months after the eligibility visit. At each visit an ABPM and DBS were performed. Results A total of 53 patients (mean age of 59±11 years, 78.7% male) with at least three months of follow-up were included. The prevalence of RH decreased from 100% in both arms to 75.0% in the intervention arm (p=0.014, n=24) and 58.6% in the control arm (p=0.001, n=29). No improvements were seen in adherence rates over time. Furthermore, no significant differences were found after three months between the two groups in the degree of RH (p=0.214), SBP (p=0.551) or adherence (p=0.746). Conclusion Measuring blood pressure and drug levels led to a decrease in the prevalence of RH. However, this improvement could not be linked to the actual intervention or improvement of adherence.

Objective: To assess the effectiveness of catheter-based renal denervation for reducing blood pressure in patients withresistant hypertension using a 5 F microtube-irrigated ablation catheter.Methods: Sixty patients with resistant hypertension were divided into two groups: a microtube-irrigated ablation catheter group and a general ablation catheter group. We conducted 12-month follow-up of all patients and recorded clinical blood pressure, ambulatory blood pressure, medication use, and biochemistry test results in both groups at the baseline and at the 12-month follow-up.Results: All patients underwent renal denervation. At the 6-month follow-up, ambulatory blood pressure in the microtube-irrigated ablation catheter group was significantly lower than in the general ablation catheter group (systolic blood pressure 142.0 ± 14.4 mmHg vs. 150.8 ± 17.9 mmHg, P = 0.04; diastolic blood pressure 81.2 ± 7.0 mmHg vs. 87.6 ± 8.0 mmHg, P = 0.002). At the 12-month follow-up, the between-group difference in ambulatory blood pressure was not statistically significant. At the 12-month follow-up, the number of antihypertensive drugs and diuretics used in the microtube-irrigated ablation catheter group was less than in the general ablation catheter group (P = 0.043). There was no statistical difference between the two groups in the results of biochemistry tests and echocardiography.Conclusion: The microtube-irrigated ablation catheter is more effective in treating hypertension than the generalablation catheter at the 6-month follow up and thus fewer antihypertensive drugs were used in the microtube-irrigatedablation catheter group than in the general ablation catheter group.

Blood Pressure Elevation

Renal sympathetic denervation (RDN) has been proposed as a new treatment modality in patients with apparent treatment resistant hypertension, a condition defined as office blood pressure elevation despite prescription of at least three antihypertensive drugs including a diuretic. However, the impressive fall in blood pressure reported after RDN in Symplicity HTN-2, the first randomised study, and multiple observational studies has not been confirmed in the US sham-controlled trial Symplicity HTN-3 and four subsequent prospective randomised studies, all published or presented in 2014. The blood pressure reduction documented in earlier studies may be largely due to non-specific effects such as improvement of drug adherence in initially poorly adherent patients (Hawthorne effect), placebo effect and regression to the mean. The overall blood pressure lowering effect of RDN seems rather limited and the characteristics of true responders remain largely unknown. Accordingly, RDN is not ready for clinical practice. In most patients with apparent drug-resistant hypertension, drug monitoring and subsequent improvement of drug adherence may prove more effective and cost-beneficial to achieve blood pressure control. In the meantime, research should aim at identifying characteristics of those few patients adherent to drug treatment and with true resistant hypertension who may respond to RDN.

Resistant hypertension is defined as blood pressure being higher than the patient's target blood pressure despite the use of three or more different types of antihypertensive drugs at the optimal dose, and one of them should be a diuretic. The evaluation of patients with resistant hypertension should first confirm that they have true resistant hypertension. By eliminating or correcting false resistance factors, such as white coat hypertension, poor blood pressure measurement technique, poor drug compliance, improper dosage or combination of antihypertensive drugs, and white coat effects and clinical inertia. Resistant hypertension therapy includes improved compliance with the use of drugs, secondary hypertension detection and treatment, use of lifestyle measures and treatment of obesity, and other comorbidities. switching to a long-acting diuretic type of thiazide like chlorthalidone could improve the BP from the patients taking hydrochlorothiazide. This review paper illustrates briefly the identification of the underlying causes of resistant hypertension and therapeutic strategies, which may contribute to the proper diagnosis and an improvement of the long term management of resistant hypertension.

Abstract Objectives First generation baroreflex activation therapy (BAT) devices showed clinical efficacy in patients with drug-resistant arterial hypertension (AHT), but the safety profile was insufficient. Data regarding efficacy of second-generation devices were generated mostly from office blood pressure (BP) measurements or short-term 24-hour ambulatory blood pressure measurements (ABPM). We present a mid-term prospective registry to evaluate the efficacy and safety of recent BAT devices. Purpose The purpose of our study was to find a method that helps patients with drug-resistant arterial hypertension to control their blood pressure. Further we sought to reduce the overall amount of antihypertensive drugs to lessen side effects, as well as the effects of polypharmacy. Methods All patients receiving Barostim neo between November 2013 and June 2019 for resistant AHT were prospectively included into this observational study. ABPM was performed at baseline, in 3-month intervals in the first year after BAT implantation and in 6-month intervals afterwards for up to 42 months. Patients were assigned into two groups of responders and non-responders. Non-responders had a mean blood pressure drop (BPD) below 5mmHg. Responders in turn were categorized into 3 sub-groups (low-BPD between 5–9 mmHg, medium-BPD between 10–19 mmHg and high-BPD ≥20 mmHg). The primary efficacy end-points were changes in systolic and diastolic BP and number of antihypertensive medications. The primary safety end point was BAT-related major adverse events (MAE). Results 64 patients (mean age 63 years, 67% males) were included. Only patients who completed a 24-hour ABPM during a follow up were counted in the statistical analysis. We had an overall responder rate of 67.8%. Out of those 15.4% had low-BPD, 38.4% medium-BPD and 46.2% had a high-BPD. Systolic BP decreased over the 3.5-years period from 168±17 mmHg to 149±19 mmHg (n=19, mean change −18.8 mmHg; 95% confidence interval [CI]: −29.32 to −8.36; p<0.0007). Diastolic BP decreased from 97±16 to 85±12 mmHg (n=19, mean change −11.7 mmHg; 95% CI: −19.2 to −4.2; p<0.0021). The mean number of antihypertensive drugs was reduced from 6.9±1.3 to 5.2±1.5 (n=19, mean change −1.7; 95% CI: −0.8 to −0.27; p<0.0009). The time course of primary end-points is shown in Fig.1. Freedom from BAT-related MAE was 93.5%. 4 perioperative complications (1 pocket bleeding, 1 pocket infection, 1 N. hypoglossus palsy, 1 hoarseness) resolved without residual side effects. There were five non BAT related deaths (7,8%) in the follow up period. Conclusion Systolic and diastolic ABP, as well as number and dosage of antihypertensive drugs decreased significantly during 3.5-years follow-up after Barostim neo implantation in 64 consecutive patients (of whom 62 completed at least one follow-up). No MAE associated with BAT were observed after the perioperative period. However, further controlled trials are needed to confirm the long-term efficacy of BAT. Figure 1.

AbstractWe aimed to develop two models to estimate first AMI and stroke/TIA, respectively, in type 2 diabetes mellitus patients, by applying backward elimination to the following variables: age, sex, duration of diabetes, smoking, BMI, and use of antihyperglycemic drugs, statins, and aspirin. As time-varying covariates, we analyzed blood pressure, albuminuria, lipid profile, HbA1c, retinopathy, neuropathy, and atrial fibrillation (only in stroke/TIA model). Both models were stratified by antihypertensive drugs. We evaluated 2980 patients (52.8% women; 67.3 ± 11.2 years) with 24,159 person-years of follow-up. We recorded 114 cases of AMI and 185 cases of stroke/TIA. The factors that were independently associated with first AMI were age (≥ 75 years vs. < 75 years) (p = 0.019), higher HbA1c (> 64 mmol/mol vs. < 53 mmol/mol) (p = 0.003), HDL-cholesterol (0.90–1.81 mmol/L vs. < 0.90 mmol/L) (p = 0.002), and diastolic blood pressure (65–85 mmHg vs. < 65 mmHg) (p < 0.001). The factors that were independently associated with first stroke/TIA were age (≥ 75 years vs. < 60 years) (p < 0.001), atrial fibrillation (first year after the diagnosis vs. more than one year) (p = 0.001), glomerular filtration rate (per each 15 mL/min/1.73 m2 decrease) (p < 0.001), total cholesterol (3.88–6.46 mmol/L vs. < 3.88 mmol/L) (p < 0.001), triglycerides (per each increment of 1.13 mmol/L) (p = 0.031), albuminuria (p < 0.001), neuropathy (p = 0.01), and retinopathy (p = 0.023).

Abstract Background Resistant (HR) and refractory hypertension (HRef) are associated with increased cardiovascular events and target-organ damage. However, appropriate HR and HRef diagnosis require good drug adherence. In this context, the “gold standard” method for assessing adherence is supervised medication intake. However, it is not clear the real utility of supervised medication intake in clinical practice. Purpose To evaluate whether hospitalization for confirming anti-hypertensive adherence in patients with HR and HRef may impact blood pressure (BP) control after hospital discharge in patients with HR or HRef suspicious at a tertiary outpatient clinic. Methods We recruited consecutive patients with HR or HRef suspicious admitted to the Hospital for confirming treatment adherence. HR was defined as uncontrolled office BP (≥140 and/or ≥90mmHg) despite using ≥3 classes at optimal doses (one of them being diuretic) or controlled BP using ≥4 classes. HRef was defined as no BP control despite using ≥5 antihypertensive drugs. Patients with suspected HRef who did not meet the criteria but full field the HR definition were named HRNoRef. During hospitalization, all patients used low sodium diet and had supervised taking of prescribed drugs by the medical team aiming BP control. We defined not only the rate of adherence and HF/HRef status but also BP and number of antihypertensive drugs at hospital discharge and in the two first return outpatient's visits. Results We studied a total of 83 patients with suspected HR/HRef (age 53±14 years; 76% females; pre-hospitalization systolic and diastolic BP: 177±28 and 106±21mmHg, respectively). Of these, 68.7% (57 patients) had suspected HRef in the outpatient clinic. The average number of antihypertensive drugs on admission was 5.3±1.3 classes. After hospitalization, the overall frequency of HR fell to 80% (66 patients). The average number of antihypertensive drugs at hospital discharge as well as systolic and diastolic BP was 4.5±1.3 classes, 131±17mmHg and 80±12mmHg, respectively (p&lt;0.001 vs. pre-hospitalization for all comparisons). Among the HR types, HRef was confirmed in only 27 patients (32.5%). During the outpatient follow-up, the patients remained with lower number of antihypertensive drugs as well as lower systolic and diastolic BP at first outpatient visit (mean returned time: 2.1±1.7months) and second outpatient visit post-discharge (mean returned time 7.1±2.6months) as compared to pre-hospitalization data: First visit: 4.3±1.2 classes, systolic: 152±24mmHg, diastolic BP: 89±17mmHg; second visit: 4.5±1.3 classes, systolic: 150±26mmHg, diastolic BP: 89±15mmHg; (p&lt;0.001 vs. pre-hospitalization for all comparisons). Conclusion Supervised medication intake during hospitalization may help not only to define the HR and HRef status but also to have impact on the number of antihypertensive drugs and lower BP values at short and mid-term follow-up.

Prescribed Medicines

Adherence to medications is an important challenge while treating chronic disease such as resistant hypertension, which is defined as uncontrolled blood pressure (BP) despite treatment with more than 3 antihypertensive drugs to achieve targets. It is possible that poor adherence is the most significant contributor to rates of pseudo-resistance among treated hypertensive patients. In this report, we describe 4 patients with apparent treatment-resistant hypertension, who received intervention to promote adherence by pharmacists who set the prescribed medicines in a weekly medication calendar and conducted a weekly pill count. The results showed that the intervention of pharmacists to medication adherence improved systolic BP in patients with apparent treatment-resistant hypertension; however, further controlled trials are required to strengthen supporting evidence.

Objective: To evaluate the effect of 24 hour systolic blood pressure (SBP) and diastolic blood pressure (DBP) variability (BPV) on renal progression in hypertensive patients with chronic kidney disease (CKD) Methods: A total 59 hypertensive patients (mean age: 54.2±14.6 years, 50.8% male) with CKD who underwent 24 hours ambulatory blood pressure measurement (ABPM) were included. Data on SBP, DBP, BPV coefficients (VC) for SBP (SBP-CV) and DBP (DBP-CV) were recorded. A decrease in e-GFR of <5 ml/min/year was considered as normal renal progression and a decrease in ≥5 ml/min/year was considered as rapid renal progression. Results: Overall, 40.6% of the patients had uncontrolled HT, while 45.8% had non-dipper pattern. Mean±SD daytime and night-time SBP and SBP-VC values were 135.3±17.9 mmHg, 128.6±23.0 mmHg, 11.7±2.8 and 9.5±3.6, respectively. Mean±SD daytime and nigh-time DBP and DBP-VC values were 84.5±13.4 mmHg, 77.2±16.1 mmHg, 13.8±3.8 and 12.0±3.7, respectively. Rapid renal progression was detected in 25.4% of patients with no significant difference in daytime, night-time and total SBP, SBP-VC, DBP and DBP-VC values between patients with rapid vs. natural renal progression. The regression analysis adjusted for age, gender, presence of DM, baseline e-GFR and dipping status revealed no significant impact of SBP-VC and DBP-VC in predicting rapid progression (p> 0.05). Conclusion: In conclusion, our finding revealed no significant association between BPV and renal progression in hypertensive patients with CKD. Larger scale prospective, randomized controlled trials with longer follow-up are needed to clarify this issue.
