The focus is on the issues related to the blood pressure (BP) measurement in this trial.</p><p>The aim of SPRINT trial was to prove the benefit of reducing systolic BP (SBP) below 120 mm Hg in high-risk hypertensive patients. A total, 9,631 highrisk participants without history of diabetes mellitus or stroke were randomly allocated to a standard treatment group (target SBP&lt;140 mm Hg) or an intensive treatment group (target SBP&lt;120 mm Hg). Significantly lower rates of all-cause mortality (by 27%) and cardiovascular events (by 25%) were observed in the intensive treatment group, compared to the standard treatment one. Therefore, the intervention was stopped early, after a mean follow-up of 3.3 years (instead of 5 years, as specified in the study protocol).</p><p>However, the SPRINT study used an unusual method of clinical BP measurement, the so-called automatic office BP (AOBP) measurement. An important feature of AOBP is that it provides significantly lower BP values, compared to the conventional clinic BP measurement. This article reviews the publications which aimed to provide an independent evaluation of the SPRINT results. It appears that if traditional clinic BP measurement was used in SPRINT, the mean SBP level in the control group could be approximately 150 mm Hg, which is substantially higher than the generally accepted threshold of 140 mm Hg. This could explain a higher prevalence of cardiovascular events in the control group. The estimated SBP level in the intensive treatment group (132-136 mm Hg) is not very different from the standard threshold.</p><p>Therefore, the SBP target in the treatment of hypertension remains unchanged at &lt;140 mm Hg. AOBP is a specific subtype of the clinic BP measurement. The currently proposed AOBP threshold (135/85 mm Hg) warrants further investigation.</p></abstract><trans-abstract xml:lang="ru"><p>В настоящей статье дан критический анализ результатов, полученных в крупном клиническом исследовании SPRINT. Основной акцент сделан на использовавшиеся в нем методы измерения артериального давления (АД).</p><p>Целью исследования SPRINT было доказательство преимущества снижения систолического АД (САД)&lt;120 мм рт.ст. у пациентов с высоким риском сердечно-сосудистых осложнений (ССО). В исследование был включен 9361 больной с высоким риском ССО, но без диабета или инсульта в анамнезе. Пациенты были рандомизированы в две группы: контрольную группу стандартного лечения с целевым значением САД&lt;140 мм рт.ст. и интенсивного лечения с целевым значением &lt;120 мм рт.ст. В группе интенсивного лечения наблюдали высокозначимое снижение общей смертности (на 27%) и ССО (на 25%) в сравнении с группой контроля. Положительный эффект был настолько значителен, что исследование было досрочно прекращено, когда средний срок наблюдения составил лишь 3,3 года (при запланированном сроке 5 лет). Обращает на себя внимание тот факт, что в исследовании вместо традиционного измерения клинического АД применялось так называемое автоматическое офисное измерение (AOBP). Известно, что метод AOBP дает в среднем более низкие результаты, чем традиционные измерения, причем разница может быть значительна. В статье дан обзор работ, целью которых была объективная оценка полученных в исследовании SPRINT результатов. По-видимому, если бы измерение клинического АД в контрольной группе проводилось общепринятым способом, то средние величины САД составили бы около 150 мм рт.ст., что значительно превышает современное пороговое значение 140 мм рт.ст. Это может быть объяснением большей частоты ССО в контрольной группе. В группе интенсивного лечения уровень клинического САД составил бы 132-136 мм рт.ст., что существенно не отличается от его порогового значения.</p><p>Результаты исследования SPRINT не дают достаточных оснований для пересмотра существующих целевых значений АД. AOBP является специфической разновидностью клинического измерения АД, его пороговые значения составляют около 135/85 мм рт.ст., однако, нуждаются в дальнейшем уточнении.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>артериальная гипертония</kwd><kwd>исследование SPRINT</kwd><kwd>клиническое артериальное давление</kwd><kwd>автоматическое офисное измерение артериального давления</kwd><kwd>целевые значения артериального давления</kwd></kwd-group><kwd-group xml:lang="en"><kwd>hypertension</kwd><kwd>SPRINT trial</kwd><kwd>clinic blood pressure</kwd><kwd>automated office blood pressure</kwd><kwd>target blood pressure levels</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Asmar R., Zanchetti A.
