REVIEW
John W Funder
Spironolactone has been marketed for over half a century as a 'potassium-sparing diuretic', used primarily in patients with ascites. With the realization that primary aldosteronism is the most common (5-13%) form of secondary hypertension, it has become widely used as a mineralocorticoid receptor antagonist. More recently, in the wake of the RALES trial, spironolactone in addition to standard therapy has been shown to be very beneficial in heart failure with a reduced ejection fraction. Despite the failure of the TOPCAT trial, spironolactone is being increasingly used in diastolic heart failure (i...

OBJECTIVES: The aim of this study was to examine the relationship between baseline heart rate (HR), change in HR from a preceding visit, and time-updated HR with subsequent outcomes in patients with heart failure with preserved ejection fraction (HFpEF) in the TOPCAT (Treatment of Preserved Cardiac Function Heart Failure With an Aldosterone Antagonist) trial. BACKGROUND: Higher resting HR and increase in HR over time in patients with heart failure are associated with adverse outcomes...

PURPOSE OF REVIEW: Spironolactone did not demonstrate benefit with respect to the primary composite endpoint in the global TOPCAT (Treatment of Preserved Cardiac Function Heart Failure with an Aldosterone Antagonist) trial in patients with chronic heart failure with preserved ejection fraction (HFpEF). We identify key lessons from the TOPCAT experience that can be applied to future HFpEF trials. RECENT FINDINGS: Subsequent analyses of TOPCAT have revealed marked regional heterogeneity in patient profiles, event rates, drug adherence, and treatment effects...

Background Although high resting heart rates are associated with adverse outcomes in heart failure with reduced ejection, the reports for heart failure with preserved ejection fraction (HFpEF) are conflicting. Design A secondary analysis was conducted in order to examine the relationship between resting heart rate and adverse outcomes in 2705 patients (mean age = 68 ± 10 years; 47% men; 88% white) with HFpEF who were in sinus rhythm from the Treatment of Preserved Cardiac Function Heart Failure with an Aldosterone Antagonist Trial (TOPCAT)...

BACKGROUND: Peripheral artery disease (PAD) in heart failure with preserved ejection fraction (HFpEF) is associated with an increased mortality risk, but the risk of individual outcomes associated with PAD in this patient group is less clear. HYPOTHESIS: PAD is associated with adverse outcomes in HFpEF, including hospitalization and specific cardiovascular outcomes. METHODS: We examined the association between PAD and adverse outcomes in 3385 patients with HFpEF (mean age, 69 ± 9...

OBJECTIVES: The aims of this study were to explore the relationship of baseline levels of natriuretic peptides (NPs) with outcomes and to test for an interaction between baseline levels of NPs and the effects spironolactone. BACKGROUND: Plasma NPs are considered to be helpful in the diagnosis of heart failure (HF) with preserved ejection fraction (HFpEF), and elevated levels are associated with adverse outcomes. Levels of NPs higher than certain cutoffs are often used as inclusion criteria in clinical trials of HFpEF to increase the likelihood that patients have HF and to select patients at higher risk for events...

AIMS: Left ventricular mechanical dyssynchrony has been described in heart failure with preserved ejection fraction (HFpEF), but its prognostic significance is not known. METHODS AND RESULTS: Of 3445 patients with HFpEF enrolled in the Treatment of Preserved Cardiac Function Heart Failure with an Aldosterone Antagonist (TOPCAT) trial, dyssynchrony analysis was performed on 424 patients (12%) by multiple speckle tracking echocardiography strain-based criteria. The primary dyssynchrony analysis was the standard deviation of the time to peak longitudinal strain (SD T2P LS)...

BACKGROUND: Gynaecological cancers are diagnosed in over 1000 women in Wales every year. We estimate that this is costing the National Health Service (NHS) in excess of £1 million per annum for routine follow-up appointments alone. Follow-up care is not evidence-based, and there are no definitive guidelines from The National Institute for Health and Care Excellence (NICE) for the type of follow-up that should be delivered. Standard care is to provide a regular medical review of the patient in a hospital-based outpatient clinic for a minimum of 5 years...

Clinical trial Data and Safety Monitoring Boards (DSMBs) have a primary obligation of ensuring study participant safety, while maintaining trial integrity. The role of DSMBs is expanding, and ideally should include post-hoc reporting of deliberative processes related to clinically important safety issues or factors that could impact on future trial designs. We describe how the TOPCAT DSMB detected, investigated, and adjudicated an unexpectedly large renal adverse event signal midway through the trial, and offer general guidelines for dealing with similar unanticipated occurrences in future trials...

Aldosterone's deleterious pathophysiological effects on the cardiovascular system if blocked by mineralcorticord antagonists (MRAs) logically should lead to improvement in heart function and outcomes in heart failure (HF). The first trial to test this hypothesis was tthe RALES trial in 1999 which treated patients with class III-IV HF with spironolactone. It showed significant reduction in mortality and cardiovascular hospitalzation rates. This was confirmed & extended in EMHASIS-HF RCT with classs II-III being treated with ACEIs & BB who received placebo or elperinone (a MRA) with again a statistically significant fall in mortality & hospitalization...

TOPCAT was a multinational clinical trial of 3,445 heart failure with preserved ejection fraction (HFpEF) patients that enrolled in 233 sites in six countries in North America, Eastern Europe and South America. Patients with a heart failure hospitalization in the last 12 months or an elevated B-type natriuretic peptide (BNP) were randomized to the mineralocorticoid receptor antagonist spironolactone vs. placebo. Sites in Russia and the Republic of Georgia provided the majority of early enrollment, primarily based on the hospitalization criterion since BNP levels were initially unavailable there...

Although patients with heart failure and preserved ejection fraction (HF-PEF) represent nearly half of the population with chronic heart failure, few evidence-based medical therapies are available. The neutral overall results of the TOPCAT trial of spironolactone in HF-PEF leave clinicians who treat heart failure with an ongoing clinical dilemma. In this review, we outline an approach to the clinical management of the patient with HF-PEF synthesizing data from available clinical trials and expert consensus.
