AbstractThe PATHWAY-2 study, funded by the British Heart Foundation, randomised 335 patients with resistant hypertension (already treated according to guidelines) to sequentially receive 12 weeks of spironolactone (25-50 mg), bisoprolol (5-10 mg), doxazosin (4-8 mg modified release) and placebo. The study design allowed drug comparisons in each patient, with 230 patients completing all cycles. Results showed that spironolactone reduced home systolic BP by 8.70 mm Hg more than placebo (<0.001), 4.26 mmHg more than bisoprolol/doxazosin (<0.001), 4.03 mm Hg more than doxazosin (<0.001), and by 4.48 mm Hg more than bisoprolol. By the end of the trial, there would only be 15 patients considered eligible for renal denervation trials in uncontrolled hypertension. PATHWAY-2 will have significant implications for patient recruitment in to other trials.
