Multidisciplinary Approach in the Treatment of Resistant Hypertension

New Drugs and Interventional Strategies for the Management of Hypertension

Essential hypertension is an important cause of cardiovascular morbidity and mortality worldwide with significant clinical and economic implications. The field of antihypertensive treatment already numbers numerous agents and classes of drugs. However, patients are still developing uncontrolled hypertension. Hence there is a continuous need for novel agents with good tolerability. Advances in this field are focusing both on pharmacotherapy, with the developments in traditional and non-traditional targets, as well as interventional techniques such as renal denervation and baroreflex activation therapy. It is likely that future strategies may involve a tailored approach to the individual patient, with genetic modulation playing a key role.

Effect of an emergency department education and empowerment intervention on uncontrolled hypertension in a predominately minority population: The AHEAD2 randomized clinical pilot trial

OBJECTIVE

To determine whether an emergency department (ED) education and empowerment intervention coupled with early risk assessment can help improve blood pressure (BP) in a high-risk population.

METHODS

A hypertension emergency department intervention aimed at decreasing disparities (AHEAD2) is a 3-arm, single-site randomized pilot trial for feasibility in an urban academic ED. A total of 150 predominantly ethnic minorities with no primary care provider and severely elevated blood pressure (BP) (≥160/100 mm Hg) were enrolled over 10 months. Participants were randomized into 1 of 3 study arms: (1) enhanced usual care (EUC), (2) ED-initiated screening, brief intervention, and referral for treatment (ED-SBIRT), or (3) ED- SBIRT plus a 48-72 hours post-acute care hypertension transition clinic (ED-SBIRT+PACHT-c). Primary outcomes were change in systolic and diastolic BP (SBP and DBP) from baseline to 9 months. Secondary outcomes were BP control (BP <140/90 mm Hg), changes in hypertension knowledge, medication adherence, and limited bedside echocardiogram (LBE) findings.

RESULTS

SBP reduction from baseline to month 9 was -26.8 (95% confidence interval [CI]: -32.8, -20.7) mm Hg for ED-SBIRT, -23.4 (95% CI: -29.5, -17.3) mm Hg for ED-SBIRT+PACHT-c, and -18.9 (95% CI: -24.9, -12.9) mm Hg for EUC. DBP decreased by -12.5 (95% CI: -16.1, -9.0) mm Hg for ED-SBIRT, -11.3 (95% CI: -14.8, -7.7) mm Hg for ED-SBIRT+PACHT-c, and -8.4 (95% CI: -11.9, -4.9) mm Hg for EUC. A multicomponent intervention compared with EUC resulted in SBP decrease of -7.9 mm Hg (95% CI: -16.4, 0.6). At 9 months, hypertension was controlled for 29.3% (95% CI: 20.3, 38.3) of intervention and 23.5% (95% CI: 11.9, 35.2) of EUC participants. All groups saw improvements in hypertension knowledge, medication adherence, and LBEs, with greater improvements in intervention groups.

CONCLUSIONS

The study findings suggest that a multicomponent intervention comprising of ED education and empowerment coupled with early risk assessment may help improve BP in a high-risk population.

Comprehensive Care Models for Cardiometabolic Disease

Purpose of Review

The high burden of cardiovascular disease and the simultaneous obesity pandemic is placing an extraordinary strain on the health care system. In the current siloed care model, patients with cardiometabolic disease receive only fractionated care from multiple specialists, leading to insufficient treatment, higher costs, and worse outcomes.

Recent Findings

The imminent need for a new care model calls for the creation of a distinct cardiometabolic specialty in conjunction with a cardiometabolic outpatient clinic dedicated to the comprehensive cardiometabolic care. The cardiometabolic clinic would consist of a diverse range of professionals relevant to comprehensive treatment.

Summary

The outpatient clinic we envision here would facilitate an interdisciplinary collaboration between specialists and deliver prevention-focused treatment to patients at risk/established cardiometabolic disease.

Development and implementation of blood pressure screening and referral guidelines for German community pharmacists

Involvement of community pharmacists in the detection and control of hypertension improves patient care. However, current European or North‐American guidelines do not provide specific guidance how to implement collaboration between pharmacists and physicians, especially when and how to refer patients with undetected or uncontrolled hypertension to a physician. The German Society of Cardiology and the ABDA – Federal Union of German Associations of Pharmacists developed and tested referral recommendations for community pharmacists, embedded in two guideline worksheets. The project included a guideline‐directed blood pressure (BP) measurement and recommendations when patients should be referred to their physician. A “red flag” referral within 4 weeks was recommended when SBP was >140 mm Hg or DBP >90 mm Hg (for subjects <80 years), and >160 mm Hg or >90 mm Hg (≥80 years) in undetected individuals, or >130 mm Hg or >80 mm Hg (<65 years) and >140 mm Hg or >80 mm Hg (≥65 years) in treated patients. BP was measured in 187 individuals (86 with known hypertension, mean [±SD] age 62 ± 15 years, 64% female, and 101 without known hypertension, 47 ± 16 years, 75% female) from 17 community pharmacies. In patients with hypertension, poorly controlled BP was detected in 55% (n = 47) and were referred. A total of 16/101 subjects without a history of hypertension were referred to their physician because of uncontrolled BP. Structured BP testing in pharmacies identified a significant number of subjects with undetected/undiagnosed hypertension and patients with poorly controlled BP. Community pharmacists could play a significant role in collaboration with physicians to improve the management of hypertension.
