title = "Systolic blood pressure and cardiovascular outcomes in heart failure with preserved ejection fraction: an analysis of the TOPCAT trial",
abstract = "Aims: Recent guidelines have advocated for stricter systolic blood pressure (SBP) control in heart failure with preserved ejection fraction (HFpEF), though data regarding the optimal SBP in HFpEF are sparse. Methods and results: We analysed participants from the Americas from the Treatment of Preserved Cardiac Function Heart Failure with an Aldosterone Antagonist (TOPCAT) study with available baseline and 8-week visit SBP data (n = 1645). We related baseline SBP to several efficacy and safety outcomes. To determine whether blood pressure lowering was responsible for the potential beneficial effects of spironolactone observed in the Americas, we assessed the randomized treatment adjusting for baseline and change in 8-week SBP. The average age was 71.7 ± 9.7 years, 50% were women, and 79% were White. Patients in the lowest baseline SBP quartile were less often female, more often White, had lower body mass index, lower baseline diastolic blood pressure and pulse pressure, and more often had atrial fibrillation. After multivariable adjustment, there was no relationship observed between baseline SBP quartiles and any outcome. Spironolactone reduced SBP by 4.4 ± 0.6 mmHg compared with placebo (and consistently across baseline SBP quartiles). There was minimal change in the treatment effect for all outcomes after adjusting for baseline SBP and 8-week change in SBP. Conclusion: No relationship was observed between baseline SBP quartiles and outcomes in TOPCAT. The anti-hypertensive effects of spironolactone did not account for the potential benefit in cardiovascular outcomes in the Americas.",

The Brigham and Women{\textquoteright}s Hospital has patents for the use of inhibitors of the renin–angiotensin system in selected survivors of myocardial infarction with Novartis Pharmaceuticals Funding Information: The design of the TOPCAT study has been described in detail previously.10 Briefly, TOPCAT was a multi-centre, international, randomized, double blinded, placebo-controlled trial of spironolactone in adults with HFpEF recruited from over 270 clinical sites. The trial was funded by the National Heart, Lung, and Blood Institute as a contract with the Brigham and Women{\textquoteright}s Hospital (Clinical Coordinating Center) and the New England Research Institute (Data Coordinating Center). Enrollment began in August 2006 and ended in January 2012, and the primary results of the trial were published in April 201411 (mean follow-up was 3.5 years). The primary aim of the TOPCAT study was to determine whether treatment with spironolactone, compared with placebo, could produce a clinically meaningful reduction in the composite outcome of cardiovascular mortality, aborted cardiac arrest, or HF hospitalization in adults with symptomatic HF and documented LV ejection fraction (LVEF) ≥45%. All study participants provided written informed consent.
