Spectrum of Primary Aldosteronism and Risk of Cardiovascular Outcomes: The Atherosclerosis Risk in Communities Study.

IMPORTANCE: Mounting evidence suggests that renin-independent aldosteronism is common and often underrecognized. Yet, whether aldosteronism across this broader spectrum is associated with incident cardiovascular disease (CVD) has not, to the authors' knowledge, been comprehensively evaluated. OBJECTIVE: To determine whether aldosterone measures are associated with incident CVD events in community-dwelling older adults. DESIGN, SETTING, AND PARTICIPANTS: This prospective cohort analysis included participants from the Atherosclerosis Risk in Communities (ARIC) study with serum aldosterone and renin levels measured in 2011 to 2013. Longitudinal analyses were conducted in March to September 2025 using Cox regression to assess associations between aldosterone parameters and incident CVD among participants free of heart failure (HF), myocardial infarction (MI), stroke, and potassium-sparing diuretic use at ARIC visit 5 (2011-2013). EXPOSURES: Serum aldosterone level and aldosterone-renin ratio (ARR). MAIN OUTCOMES AND MEASURES: Incident HF hospitalization, atrial fibrillation (AF), ischemic stroke, MI, and a composite of these events plus all-cause death. RESULTS: Among 3477 individuals free of baseline CVD (mean [SD] age, 74.8 [4.9] years; 2139 female [61.5%]), the median (IQR) aldosterone level was 5.1 (3.0-8.3) ng/dL (to convert to picomoles per liter, multiply by 27.74), renin activity was 0.78 (0.41-1.90) ng/mL per hour, and ARR was 5.9 (2.2-12.3) ng/dL per ng/mL/h. Over 9 years of follow-up, higher ARR was associated with the composite outcome (adjusted hazard ratio [aHR], 1.04; 95% CI, 1.01-1.08 per doubling), stroke (aHR, 1.13; 95% CI, 1.02-1.26), and AF (aHR, 1.10; 95% CI, 1.05-1.15) but not with incident HF hospitalization (aHR, 1.02; 95% CI, 0.96-1.07) or MI (aHR, 1.01; 95% CI, 0.92-1.12). CONCLUSIONS AND RELEVANCE: The findings of this cohort study underscore a spectrum of primary aldosteronism, in which higher ARR was independently associated with increased risks of AF and ischemic stroke among older adults, supporting the aldosterone pathway as a potential target for CVD prevention.

Finerenone and Cardiovascular Outcomes According to Baseline Kidney Function in Patients With Heart Failure: The FINEARTS-HF Trial.

BACKGROUND: Finerenone is known to reduce the risk of worsening heart failure (HF) events and cardiovascular (CV) death in patients with HF with mildly reduced or preserved ejection fraction. OBJECTIVES: The authors explored whether the benefit of finerenone among patients with HF with mildly reduced or preserved ejection fraction differs according to baseline measures of kidney function. METHODS: FINEARTS-HF (Finerenone Trial to Investigate Efficacy and Safety Superior to Placebo in Patients With Heart Failure) was a global, randomized clinical trial of finerenone vs placebo among patients with HF with mildly reduced or preserved ejection fraction. Finerenone was titrated to 20 mg/d if the estimated glomerular filtration rate (eGFR) was &#x2264;60 mL/min/1.73 m2 or 40 mg/d if eGFR was >60 mL/min/1.73 m2. The authors used a semiparametric proportional rates method, stratified by left ventricular ejection fraction (<60%; &#x2265;60%) and region, to assess for differential treatment effects on the composite of total HF events and CV death according to the baseline eGFR (continuous and categories [&#x2265;60 mL/min/1.73 m2, 45 to <60 mL/min/1.73 m2, <45 mL/min/1.73 m2] and urine albumin-creatinine ratio (UACR) (<30 mg/g, 30 to <300 mg/g, &#x2265;300 mg/g). RESULTS: The effect of finerenone to reduce the primary endpoint of total HF events and CV death did not significantly differ according to baseline eGFR (Pinteraction = 0.14 and 0.07 for continuous and categorical eGFR, respectively) with rate ratio 0.72 (95% CI: 0.59-0.88) for eGFR &#x2265;60 mL/min/1.73 m2, 0.83 (95% CI: 0.65-1.06) for eGFR 45 to <60 mL/min/1.73 m2, and 1.02 (95% CI: 0.83-1.26) for eGFR <45 mL/min/1.73 m2. The corresponding absolute event rates were 9.2 vs 12.5, 16.5 vs 19.9, and 28.0 vs 28.0 per 100 patient-years for finerenone vs placebo, respectively. Similar results were noted for total worsening HF events. Finerenone lowered the risk of the composite CV outcome similarly across baseline categories of UACR (Pinteraction = 0.48). CONCLUSIONS: In the FINEARTS-HF trial (where the target dose of finerenone was determined by baseline kidney function), the effect of finerenone to reduce the composite of cardiovascular death and total HF events did not significantly differ across a range of baseline eGFR and UACR.
