2. Introduction
Hypertension is world’s leading risk factor for CVD, stroke, disability and death.
hypertension was defined as resistant to treatment when appropriate lifestyle
measures and treatment with optimal or best tolerated doses of three or more
drugs (a Thiazide/Thiazide-like diuretic, an RAS-blocker and a CCB) fail to lower
office BP to <140/90mm Hg.
A large proportion of hypertensive adults, still fail to achieve their recomended BP
treatment targets.
These individuals remain at increased risk for target organ damage, morbidity and
mortality despite ongoing anti-hypertensive drug therapy.

hypertension.

CKD (eGFR 15–29
ml/min/1.73 m2)
and poorly controlled
hypertension, showed an
about roughly 10 mmHg 24-h
SBP reduction with
chlortalidone versus placebo,
and the BP-lowering effect
was particularly evident in
patients already on loop
diuretics
8. Selective nonsteroidal MRAs such as finerenone (approved for the treatment in diabetic kidney disease)
Esaxerenone (approved for the treatment of hypertension in Japan),
Ocedurenone (KBP-5074, in development for resistant hypertension in CKD) ,0.25–0.50 mg/day reduced
BP in patients with resistant hypertension and stage 3b/4 CKD with a higher incidence of hyperkalemia at
the highest dose
Finally, the use of selective aldosterone synthase inhibitors such as baxdrostat has been shown to
effectively lower BP in patients with resistant hypertension in a phase 2 trial.
When spironolactone and other MRAs are not tolerated or contraindicated (i.e. in CKD stage 4,
eGFR <30 ml/min),bisoprolol (5–10 mg/day), doxazosin extended release (4–8 mg/day)
or a centrally acting agent such as the alpha adrenergic receptor agonists (clonidine, 0.1–0.3
mg twice a day) can be used as alternatives
9. In obese patients,GLP1 receptor agonists can reduce body weight [759], modestly lower BP and improve
CV prognosis in patients with type 2 diabetes or with established CVD
Bariatric surgery can lower BP, CV risk factors and risk of CV events in severely obese patients and may,
thus, reduce the burden of antihypertensive medication when these patients have resistant
hypertension
In patients eligible for treatment with SGLT2is their use may add a moderate BP-lowering effect to the
background antihypertensive therapy for resistant hypertensive patients
Finally, compared with valsartan alone, the sacubitril–valsartan combination did not lower
hospitalization for HF and death in patients with HFpEF , but did reduce significantly the NYHA class of
the patients

12. Carotid baroreceptor stimulation
Stretch-sensitive baroreceptors located in the carotid sinus and the aortic arch are involved in
short-term and long-term BP regulation.
Carotid baroreceptor stimulation was associated with a reduction of sympathetic nerve activity
in studies on hypertensive patients
The first-generation bilateral electrical stimulation device (Rheos, CVRx) was tested in a double-
blind, randomized, sham-controlled pivotal trial, which included 265 patients with resistant
hypertension [798].
At 6 months, the office BP fall was significantly larger in the treatment group compared with the
sham group. However, the study failed to meet two of the five co-primary endpoints, and safety
was not established.
13. In a small, noncontrolled, open-label, first-in-human CALM-FIM study, 30 patients underwent
implantation of the MobiusHD system (Vascular Dynamics). At 6 months, there were significant
reductions in both office and ambulatory BP compared with baseline, which appeared to be
maintained through 36 months
14. Other device-based treatments
ROX CONTROL HTN trial- fixed diameter iliac arteriovenous anastomosis with a
catheter-based device (ROX coupler; ROX Medical) was investigated in resistant
hypertension to lower peripheral vascular resistance
15. Withdrawal of BP-lowering drugs
Drug class Effects of abrupt withdrawal
CCBs • Risk of angina
BBs • Risk of angina and other complications
in CAD patients
Centrally acting agents • Sympathetic overactivity (nervousness,
tachycardia, headache, agitation and
nausea for 36–72 h after drug cessation)
• Rapid rebound BP increase even above
pretreatment levels
• Angina and other complications in
CAD patients
Diuretics • Fluid retention, edema, HF
decompensation
