Abstract

Context. Blood pressure control (<140/90 mm Hg) rates for hypertension fall far short of the US national goal of 50% or more. Achievable control rates in varied practice settings and geographic regions and factors that predict improved blood pressure control are not well identified. Objective. To determine the success and predictors of blood pressure control in a large hypertension trial involving a multiethnic population in diverse practice settings. Design. The Antihypertensive and Lipid‐Lowering Treatment to Prevent Heart Attack Trial is a randomized, double‐blind, active‐controlled clinical trial with a mean follow‐up of 4.9 years. Participant enrollment began in February 1994 and follow‐up was completed in March 2002. Setting. A total of 623 centers in the United States, Canada, and the Caribbean. Participants. A total of 33,357 participants (aged ≥55 years) with hypertension and at least one other coronary heart disease risk factor. Interventions. Participants were randomly assigned to receive (double‐blind) chlorthalidone, 12.5–25 mg/d (n=15,255), amlodipine 2.5–10 mg/d (n=9048), or lisinopril 10–40 mg/d (n=9054) after other medication was discontinued. Doses were increased within these ranges and additional drugs from other classes were added as needed to achieve blood pressure control (<140/90 mm Hg). Main Outcome Measures. The outcome measures for this report are systolic and diastolic blood pressure, the proportion of participants achieving blood pressure control (<140/90 mm Hg), and the number of drugs required to achieve control in all three groups combined. Results. Mean age was 67 years, 47% were women, 35% black, 36% diabetic; 90% were on antihypertensive drug treatment at entry. At the first of two pre‐randomization visits, blood pressure was <140/90 mm Hg in only 27.4% of participants. After 5 years of follow‐up, the percent controlled improved to 66%. Systolic blood pressure was <140 mm Hg in 67% of participants, diastolic blood pressure was <90 mm Hg in 92%, the mean number of drugs prescribed was 2.0±1.0, and the percent on ≥2 drugs was 63%. Blood pressure control varied by geographic regions, practice settings, and demographic and clinical characteristics of participants. Conclusions. These data demonstrate that blood pressure may be controlled in two thirds of a multiethnic hypertensive population in diverse practice settings. Systolic blood pressure is more difficult to control than diastolic blood pressure, and at least two antihypertensive medications are required for most patients to achieve blood pressure control. It is likely that the majority of people with hypertension could achieve a blood pressure <140/90 mm Hg with the antihypertensive medications available today.

  • A disproportionately higher prevalence of resistant hypertension among blacks has been suggested to reflect a contribution by genetic factors, but environmental or psychosocial determinants of blood pressure control are also possible.

    “A disproportionately higher prevalence of RH among blacks67,68 has been suggested to reflect a contribution by genetic factors, but environmental or psychosocial determinants of BP control are also possible.69”
  • Patients with chronic kidney disease and apparent treatment-resistant hypertension are at higher risk for cardiovascular disease events and renal events (50% decrease in estimated glomerular filtration rate or incident end-stage renal disease) compared with patients with chronic kidney disease without apparent treatment-resistant hypertension.

    “Thus, patients with CKD and aTRH are at higher risk for CVD events and renal events (50% decrease in eGFR or incident end-stage renal disease) compared with patients with CKD without aTRH.67”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
