Abstract Objective The cardiometabolic risk cluster metabolic syndrome (MS) includes ≥ 3 of elevated fasting glucose, hypertension, elevated triglycerides, reduced high-density lipoprotein ...cholesterol (HDL-c), and increased waist circumference. Each can be affected by physical activity and diet. Our objective was to determine whether determine whether baseline physical activity and/or diet behavior impact MS in the course of a large pharmaceutical trial. Materials/Methods This was an observational study from NAVIGATOR, a double-blind, randomized (nateglinide, valsartan, both, or placebo), controlled trial between 2002 and 2004. We studied data from persons (n = 9306) with impaired glucose tolerance and cardiovascular disease (CVD) or CVD risk factors; 7118 with pedometer data were included in this analysis. Physical activity was assessed with 7-day pedometer records; diet behavior was self-reported on a 6-item survey. An MS score (MSSc) was calculated using the sum of each MS component, centered around the Adult Treatment Panel III threshold, and standardized according to sample standard deviation. Excepting HDL-c, assessed at baseline and year 3, MS components were assessed yearly. Follow-up averaged 6 years. Results For every 2000-step increase in average daily steps, there was an associated reduction in average MSSc of 0.29 (95% CI- 0.33 to- 0.25). For each diet behavior endorsed, there was an associated reduction in average MSSc of 0.05 (95% CI- 0.08 to- 0.01). Accounting for the effects of pedometer steps and diet behavior together had minimal impact on parameter estimates with no significant interaction. Relations were independent of age, sex, race, region, smoking, family history of diabetes, and use of nateglinide, valsartan, aspirin, antihypertensive, and lipid-lowering agent. Conclusions Baseline physical activity and diet behavior were associated independently with reductions in MSSc such that increased attention to these lifestyle elements provides cardiometabolic benefits. Thus, given the potential to impact outcomes, assessment of physical activity and diet should be performed in pharmacologic trials targeting cardiometabolic risk.
ABSTRACT
Aim
Steroidal mineralocorticoid receptor antagonists (MRAs), spironolactone and eplerenone, are strongly recommended in the treatment of patients with chronic heart failure (HF) with reduced ...left ventricular ejection fraction (LVEF), but the balance of efficacy and safety in those with higher LVEF has not been well established. Broad use of steroidal MRAs has further been limited in part due to safety concerns around risks of hyperkalaemia, gynecomastia, and kidney dysfunction. These risks may be mitigated by the unique pharmacological properties of the non‐steroidal MRA finerenone. The FINEARTS‐HF trial is designed to evaluate the long‐term efficacy and safety of the selective non‐steroidal MRA finerenone among patients with HF with mildly reduced or preserved ejection fraction.
Methods
FINEARTS‐HF is a global, multicentre, event‐driven randomized trial evaluating oral finerenone versus matching placebo in symptomatic patients with HF with LVEF ≥40%. Adults (≥40 years) with HF with New York Heart Association class II–IV symptoms, LVEF ≥40%, evidence of structural heart disease, and diuretic use for at least the previous 30 days were eligible. All patients required elevated natriuretic peptide levels: for patients in sinus rhythm, N‐terminal pro‐B‐type natriuretic peptide (NT‐proBNP) ≥300 pg/ml (or B‐type natriuretic peptide BNP ≥100 pg/ml) were required, measured within 30 days (in those without a recent worsening HF event) or within 90 days (in those with a recent worsening HF event). Qualifying levels of NT‐proBNP or BNP were tripled if a patient was in atrial fibrillation at screening. Estimated glomerular filtration rate <25 ml/min/1.73 m2 or serum potassium >5.0 mmol/L were key exclusion criteria. Patients were enrolled irrespective of clinical care setting (whether hospitalized, recently hospitalized, or ambulatory). The primary endpoint is the composite of cardiovascular death and total (first and recurrent) HF events. The trial started on 14 September 2020 and has validly randomized 6001 participants across 37 countries. Approximately 2375 total primary composite events are targeted.
Conclusions
The FINEARTS‐HF trial will determine the efficacy and safety of the non‐steroidal MRA finerenone in a broad population of hospitalized and ambulatory patients with HF with mildly reduced or preserved ejection fraction.

Although recent randomized clinical trials have demonstrated the advantages of heart failure (HF) therapy in both frail and not frail patients, there is insufficient information on the use of HF ...therapy based on frailty status in a real-world setting. The aim was to examine how frailty status in HF patients associates with use of HF therapy and with clinical outcomes.
Patients with new-onset HF between 2014 and 2021 were identified using the nationwide Danish registers. Patients across the entire range of ejection fraction were included. The associations between frailty status (using the Hospital Frailty Risk Score) and use of HF therapy and clinical outcomes (all-cause mortality, HF hospitalization, and non-HF hospitalization) were evaluated using multivariable-adjusted Cox models adjusting for age, sex, diagnostic setting, calendar year, comorbidities, pharmacotherapy, and socioeconomic status. Of 35 999 participants (mean age 69.1 years), 68% were not frail, 26% were moderately frail, and 6% were severely frail. The use of HF therapy was significantly lower in frailer patients. The hazard ratio (HR) for angiotensin-converting enzyme inhibitor/angiotensin receptor blocker initiation was 0.74 (95% confidence interval 0.70-0.77) and 0.48 (0.43-0.53) for moderate frailty and severe frailty, respectively. For beta-blockers, the corresponding HRs were 0.74 (0.71-0.78) and 0.51 (0.46-0.56), respectively, and for mineralocorticoid receptor antagonists, 0.83 (0.80-0.87) and 0.58 (0.53-0.64), respectively. The prevalence of death and non-HF hospitalization increased with frailty status. The HR for death was 1.55 (1.47-1.63) and 2.32 (2.16-2.49) for moderate and severe frailty, respectively, and the HR for non-HF hospitalization was 1.37 (1.32-1.41) and 1.82 (1.72-1.92), respectively. The association between frailty status and HF hospitalization was not significant (HR 1.08 1.02-1.14 and 1.08 0.97-1.20, respectively).
In real-world HF patients, frailty was associated with lower HF therapy use and with a higher incidence of clinical outcomes including mortality and non-HF hospitalization.

Clinical trials are our best vehicle for turning medical information that we may think is true into evidence that we know, within reasonable limits, to be true. Since the introduction of random ...assignments to treatment in the 1930s,

the clinical trial has been in continuous evolution. Among the major milestones have been the development of methods to perform randomization; the convening of data and safety monitoring committees; the formulation of stopping guidelines for safety, efficacy, and futility; and many others. Indeed, the clinical trial landscape is far different today from what it was over 80 years ago, when investigators first . . .
Patients with type 2 diabetes mellitus (T2DM) are at high risk of developing cardiovascular (CV) and renal disease. We examined the burden of, and risk of death following, CV and renal events in the ...Aliskiren Trial in Type 2 Diabetes Using Cardio-Renal Endpoints (ALTITUDE), a randomized trial of alikiren vs. placebo.
We followed 8561 patients with T2DM and evidence of chronic kidney disease, CV disease, or both in ALTITUDE until the first non-fatal CV or renal event of myocardial infarction (MI), stroke, heart failure (HF), and end-stage renal disease (ESRD; initiation of dialysis, renal transplantation, or a serum creatinine concentration above 6.0 mg/dL) and then to death or censoring. Time-updated multivariable Cox models were used to estimate the relative risk of death following each event. In total 1008 patients (12%) experienced at least one first non-fatal CV or renal event (4.1% HF, 2.8% MI, 2.8% stroke, and 2.2% ESRD). Death occurred subsequently in 26.4% of those experiencing a first HF event, 29.7% of those experiencing an MI event, 23.7% of those experiencing a stroke, and 14.7% of those experiencing ESRD, and in 6.5% (488) of the 7553 patients (88%) who did not experience a non-fatal CV or renal event. Compared with patients who did not experience a non-fatal event, the adjusted hazard ratio for death was 5.9 (95% confidence interval 4.6-7.6) after HF, 9.7 (7.5-12.6) after MI, 7.1 (5.3-9.5) after stroke, and 5.8 (3.7-9.0) after ESRD.
The majority of deaths occurred in patients who did not experience a non-fatal CV or renal event, although the risk of death was higher following an event. Our findings illustrate continuing opportunities to reduce morbidity and mortality in patients with type 2 diabetes.
Aims
In heart failure with reduced ejection fraction (HFrEF), there is an ‘obesity paradox’, where survival is better in patients with a higher body mass index (BMI) and weight loss is associated ...with worse outcomes. We examined the effect of a sodium–glucose co‐transporter 2 inhibitor according to baseline BMI in the Dapagliflozin And Prevention of Adverse‐outcomes in Heart Failure trial (DAPA‐HF).
Methods and results
Body mass index was examined using standard categories, i.e. underweight (<18.5 kg/m2); normal weight (18.5–24.9 kg/m2); overweight (25.0–29.9 kg/m2); obesity class I (30.0–34.9 kg/m2); obesity class II (35.0–39.9 kg/m2); and obesity class III (≥40 kg/m2). The primary outcome in DAPA‐HF was the composite of worsening heart failure or cardiovascular death. Overall, 1348 patients (28.4%) were under/normal‐weight, 1722 (36.3%) overweight, 1013 (21.4%) obesity class I and 659 (13.9%) obesity class II/III. The unadjusted hazard ratio (95% confidence interval) for the primary outcome with obesity class 1, the lowest risk group, as reference was: under/normal‐weight 1.41 (1.16–1.71), overweight 1.18 (0.97–1.42), obesity class II/III 1.37 (1.10–1.72). Patients with class I obesity were also at lowest risk of death. The effect of dapagliflozin on the primary outcome and other outcomes did not vary by baseline BMI, e.g. hazard ratio for primary outcome: under/normal‐weight 0.74 (0.58–0.94), overweight 0.81 (0.65–1.02), obesity class I 0.68 (0.50–0.92), obesity class II/III 0.71 (0.51–1.00) (P‐value for interaction = 0.79). The mean decrease in weight at 8 months with dapagliflozin was 0.9 (0.7–1.1) kg (P < 0.001).
Conclusion
We confirmed an ‘obesity survival paradox’ in HFrEF. We showed that dapagliflozin was beneficial across the wide range of BMI studied.

Patients with heart failure (HF) often suffer from a range of comorbidities, which may affect their health status. The aim of this study was to assess the impact of different comorbidities on health ...status in patients with HF and reduced (HFrEF) and preserved ejection fraction (HFpEF).
Using individual patient data from HFrEF (ATMOSPHERE, PARADIGM-HF, DAPA-HF) and HFpEF (TOPCAT, PARAGON-HF) trials, we examined the Kansas City Cardiomyopathy Questionnaire (KCCQ) domain scores and overall summary score (KCCQ-OSS) across a range of cardiorespiratory (angina, atrial fibrillation AF, stroke, chronic obstructive pulmonary disease COPD) and other comorbidities (obesity, diabetes, chronic kidney disease CKD, anaemia). Of patients with HFrEF (n = 20 159), 36.2% had AF, 33.9% CKD, 33.9% diabetes, 31.4% obesity, 25.5% angina, 12.2% COPD, 8.4% stroke, and 4.4% anaemia; the corresponding proportions in HFpEF (n = 6563) were: 54.0% AF, 48.7% CKD, 43.4% diabetes, 53.3% obesity, 28.6% angina, 14.7% COPD, 10.2% stroke, and 6.5% anaemia. HFpEF patients had lower KCCQ domain scores and KCCQ-OSS (67.8 vs. 71.3) than HFrEF patients. Physical limitations, social limitations and quality of life domains were reduced more than symptom frequency and symptom burden domains. In both HFrEF and HFpEF, COPD, angina, anaemia, and obesity were associated with the lowest scores. An increasing number of comorbidities was associated with decreasing scores (e.g. KCCQ-OSS 0 vs. ≥4 comorbidities: HFrEF 76.8 vs. 66.4; HFpEF 73.7 vs. 65.2).
Cardiac and non-cardiac comorbidities are common in both HFrEF and HFpEF patients and most are associated with reductions in health status although the impact varied among comorbidities, by the number of comorbidities, and by HF phenotype. Treating/correcting comorbidity is a therapeutic approach that may improve the health status of patients with HF.
