Implementation of Multifaceted Patient-Centered Treatment Strategies for Intensive Blood Pressure Control (IMPACTS): Rationale and design of a cluster-randomized trial. Am Heart J 2020; 230:13-24. [PMID: 32827458 PMCID: PMC7437489 DOI: 10.1016/j.ahj.2020.08.009] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/22/2020] [Accepted: 08/14/2020] [Indexed: 12/26/2022]
Abstract
BACKGROUND The Systolic Blood Pressure Intervention Trial (SPRINT) reported that intensive blood pressure (BP) treatment reduced cardiovascular disease and mortality compared to standard BP treatment in hypertension patients. The next important question is how to implement more intensive BP treatment in real-world clinical practice. We designed an effectiveness-implementation hybrid trial to simultaneously test the effectiveness of a multifaceted intervention for intensive BP treatment and its feasibility, fidelity, and sustainability in underserved hypertension patients. METHODS Implementation of Multifaceted Patient-Centered Treatment Strategies for Intensive Blood Pressure Control (IMPACTS) is a cluster randomized trial conducted in 36 Federally Qualified Health Center clinics in Louisiana and Mississippi. Federally Qualified Health Center clinics were randomized to either a multifaceted intervention for intensive BP treatment, including protocol-based treatment using the SPRINT intensive BP management algorithm, dissemination of SPRINT findings, BP audit and feedback, home BP monitoring, and health coaching, or enhanced usual care. Difference in mean systolic BP change from baseline to 18 months is the primary clinical effectiveness outcome, and intervention fidelity, measured by treatment intensification and medication adherence, is the primary implementation outcome. The planned sample size of 1,260 participants (36 clinics with 35 participants each) has 90% power to detect a 5.0-mm Hg difference in systolic BP at a .05 significance level and 80% follow-up rate. CONCLUSIONS IMPACTS will generate critical data on the effectiveness and implementation of a multifaceted intervention for intensive BP treatment in real-world clinical practice and could directly impact the BP-related disease burden in minority and low-income populations in the United States.

Sex Differences of Patients With Systemic Hypertension (From the Analysis of the Systolic Blood Pressure Intervention Trial [SPRINT]). Am J Cardiol 2018; 122:985-993. [PMID: 30072129 DOI: 10.1016/j.amjcard.2018.05.046] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/14/2018] [Revised: 05/22/2018] [Accepted: 05/30/2018] [Indexed: 01/21/2023]
Abstract
There are differences in the incidence, pathophysiology, and long-term effects of hypertension between women and men. We assessed sex-specific benefit-risk tradeoffs of different blood pressure (BP) goals in patients enrolled in the Systolic Blood Pressure Intervention Trial (SPRINT) after propensity score matching those with standard therapy (systolic BP <140 mm Hg) to those with intensive therapy (systolic BP <120 mm Hg; n = 9,106). Cox regression was conducted to compare standard versus intensive therapy in women and men with the composite outcome of myocardial infarction, other acute coronary syndromes, stroke, heart failure, or death from cardiovascular causes. Women were generally healthier at baseline and had a lower cardiovascular risk. Men on intensive therapy had a lower risk of the composite outcome compared to those on standard therapy (hazard ratio [HR] 0.70, 95% confidence interval [CI] 0.57 to 0.86, p = 0.001) while in women no differences between therapy groups were observed (HR 0.82 [0.60 to 1.12], p = 0.206). For safety outcomes, women and men had increased risk of related serious adverse events with intensive treatment (HR 1.52 [1.06 to 2.18], p = 0.023 and HR 2.07 [1.55 to2.77], p < 0.001, respectively). In conclusion, our study demonstrated that women did not benefit from intensive compared to standard BP control. A potential explanation for this may be the lower baseline cardiovascular risk in women.

Abstract
Atherosclerotic cardiovascular disease (ASCVD) is a leading global cause of death and accounts for most deaths among individuals with diabetes. This article reviews the latest observational and trial data on changes in the relationship between diabetes and ASCVD risk, remaining gaps in how the role of each risk factor is understood, and current knowledge about specific interventions. Differences between high-income countries and low-income and middle-income countries are examined, barriers and facilitators are discussed, and a discussion around the concept of ideal cardiovascular health factors (Life's Simple 7) is focused on.
