Hypertension Clinical Trials

The ACC/AHA treatment target for most adults with hypertension is <130/80 mm Hg when tolerated. For noninstitutionalized, ambulatory, community-dwelling adults aged 65 years or older, use systolic blood pressure <130 mm Hg as the target if tolerated. The change from prior <140/90 mm Hg goals was driven by SPRINT and subsequent trial syntheses showing lower cardiovascular event rates with more intensive control.

Do not treat a numerical target in isolation. In older adults, dizziness with intensive control and possible ischemic risk at very low diastolic pressure can alter the benefit-harm balance; one cohort analysis associated diastolic blood pressure <60 mm Hg with higher cardiovascular event risk among high-risk treated patients whose systolic blood pressure was <130 mm Hg. Reassess symptoms, orthostatic measurements, coronary disease burden, and adherence burden before further intensification. AHA JournalsAHA JournalsHypertension Pharmacological Treatment in Adults

Trial evidence supports initiation of pharmacologic therapy at an average systolic blood pressure ≥140 mm Hg for primary or secondary prevention. In patients with diabetes, chronic kidney disease, or coronary artery disease, lower targets may be beneficial, but subgroup evidence is less precise; individualize intensification when adverse effects, frailty, or low diastolic pressure limit treatment.

After an elevated office blood pressure suggests hypertension, confirm the diagnosis with ambulatory blood pressure monitoring or home blood pressure monitoring. The U.S. Preventive Services Task Force identifies ambulatory monitoring as the reference standard for out-of-office confirmation, and higher out-of-office blood pressure confers cardiovascular risk independent of office blood pressure.

When interpreting ambulatory monitoring using thresholds historically corresponding to office blood pressure ≥140/90 mm Hg, elevated daytime blood pressure is ≥135/85 mm Hg, 24-hour blood pressure is ≥130/80 mm Hg, and nighttime blood pressure is ≥120/70 mm Hg. Use the 24-hour result to establish whether apparent office treatment failure represents sustained uncontrolled blood pressure rather than an office-only elevation.

For treated patients with persistently elevated office readings, obtain home or ambulatory data before adding medications when feasible. This step is particularly important before classifying resistant hypertension or referring for renal denervation, because resistant hypertension requires elevated ambulatory blood pressure despite optimized treatment after adherence and secondary causes have been addressed.

For most adults requiring drug treatment, select from an ACE inhibitor or ARB, a thiazide-type diuretic, and a calcium-channel blocker; combination therapy is advised in most adults with hypertension. The ACC/AHA approach favors chlorthalidone among thiazide-type diuretics because it was used in many landmark event-based randomized trials. jaccjaccHarmonization of the American College of Cardiology/American Heart Association and European Society of Cardiology/European Society of Hypertension Blood Pressure/Hypertension Guidelines: Comparisons, Reflections, and Recommendations

Initiate two agents when systolic blood pressure is ≥140 mm Hg or diastolic blood pressure is ≥90 mm Hg and the average pressure is >20/10 mm Hg above the individual target. This strategy is intended to shorten time above target and avoid serial monotherapy escalation in markedly uncontrolled hypertension. jaccjaccHarmonization of the American College of Cardiology/American Heart Association and European Society of Cardiology/European Society of Hypertension Blood Pressure/Hypertension Guidelines: Comparisons, Reflections, and Recommendations

For Black patients beginning drug therapy, include a thiazide-type diuretic or calcium-channel blocker in the initial regimen. Fixed-dose combinations can simplify treatment, but many U.S. combination products contain hydrochlorothiazide rather than chlorthalidone and may use lower diuretic doses than trial-based chlorthalidone regimens; assess the actual ingredients before assuming class equivalence. jaccjaccHarmonization of the American College of Cardiology/American Heart Association and European Society of Cardiology/European Society of Hypertension Blood Pressure/Hypertension Guidelines: Comparisons, Reflections, and Recommendations

Treat apparent resistant hypertension as a diagnostic category first. True resistant hypertension is elevated ambulatory blood pressure despite optimized antihypertensive therapy in a patient who is fully adherent after secondary hypertension has been excluded. Therefore, reconcile every drug and dose, assess adherence directly, obtain ambulatory blood pressure monitoring, and complete secondary-cause evaluation before escalating to a device-based intervention.

Renal denervation should not be positioned as a substitute for optimized multidrug therapy. Earlier randomized evidence did not support routine use of renal denervation, baroreflex activation therapy, or arteriovenous anastomosis in most patients with resistant hypertension. More recent randomized trial synthesis found a mean office systolic blood pressure difference of −8.5 mm Hg, 24-hour systolic blood pressure difference of −3.6 mm Hg, and daytime ambulatory systolic blood pressure difference of −3.9 mm Hg favoring renal denervation at primary follow-up.

Use the ambulatory effect size when counseling patients: the pooled between-group 24-hour systolic reduction was modest, and the meta-analysis found no significant difference in serious adverse events at primary follow-up across four trials reporting this outcome. A patient considering renal denervation should understand that drug therapy, adherence, and blood pressure monitoring remain necessary after the procedure.

Target trials support lower achieved blood pressure goals but do not eliminate the need for individualized tolerability assessment. SPRINT and subsequent syntheses supported more intensive control, whereas evidence in diabetes, chronic kidney disease, and coronary artery disease supports lower targets with less precise subgroup estimates; use comorbidity to increase attention to cardiovascular risk, not to bypass adverse-effect assessment.

Measurement trials and observational evidence establish that office and out-of-office pressures are not interchangeable. When the question is whether to diagnose hypertension, escalate a regimen, or classify treatment resistance, ambulatory monitoring answers a different and more actionable question than a repeat office reading.

Device trials answer whether renal denervation adds blood-pressure lowering over control, not whether it replaces medicines. The pooled ambulatory systolic effect is smaller than the office effect, reinforcing the need to use 24-hour blood pressure rather than office response alone to judge procedural benefit.
