CardioNerds (Drs. Apoorva Gangavelli, Jenna Skowronski, and Hannah Every) discuss the continuum of prevention and heart failure with Drs. Anu Lala and Martha Gulati. Grounded in a clinical case of a 55-year-old woman with uncontrolled hypertension, type 2 diabetes, and obesity who is on the trajectory toward heart failure, this episode unpacks a paradigm-shifting framework from a joint HFSA/ASPC Scientific Statement. The discussion explores how prevention should not be siloed from heart failure management but rather integrated across a patient's lifespan—from primary prevention in at-risk individuals, to secondary prevention in those with established heart failure, to tertiary prevention in patients with advanced therapies such as LVADs and heart transplantation. The experts highlight the importance of aggressive risk factor management, biomarker-guided screening, the AHA's Life's Essential 8, and the need for multidisciplinary collaboration and systems-level change to shift heart failure care from reactive to proactive. Audio editing for this episode was performed by CardioNerds Intern, Dr. Julia Marques Fernandes.

Pearls
Systemic inflammatory diseases are associated with an elevated CVD risk that has significant implications for early detection, risk Heart failure prevention is a continuum, not a checkpoint. Prevention applies at every stage—from at-risk (Stage A) through advanced/post-transplant care—and every clinical encounter is an opportunity to intervene. The AHA's Life's Essential 8 (diet, physical activity, nicotine exposure, sleep, BMI, blood lipids, blood glucose, blood pressure) forms the foundation at every stage.
Hypertension carries the highest population-attributable risk for heart failure of any modifiable risk factor. In the Framingham Heart Study, 91% of patients with newly diagnosed HF had pre-existing hypertension. The SPRINT trial demonstrated a 38% reduction in HF incidence with intensive blood pressure targets (<120 mm Hg systolic). Agent selection matters: ACE inhibitors, ARBs, and thiazide diuretics should be prioritized for HF prevention.
Overlapping risk factors should prompt parallel, not sequential, intervention. Pharmacotherapies such as SGLT2 inhibitors and GLP-1 receptor agonists target multiple pathways simultaneously (diabetes, obesity, CKD, HF risk), making them ideal for patients with cardiometabolic multimorbidity. The cardio-kidney-metabolic (CKM) syndrome framework reinforces this integrated approach.
Biomarker screening with BNP/NT-proBNP should be used proactively in high-risk populations, not just reactively in the emergency department. Even modestly elevated natriuretic peptide levels (e.g., BNP >30 ng/L or NT-proBNP >125 ng/L) identify individuals at heightened risk for progression to symptomatic HF. The ACC/AHA/HFSA guidelines give a Class IIa recommendation for natriuretic peptide screening in at-risk patients. Urine albumin-to-creatinine ratio (UACR) is an underutilized screening tool that provides additional insight into CKM risk.
The heart failure label does not close the prevention window—it accentuates it. Secondary prevention through GDMT optimization (quadruple therapy in HFrEF) and continued risk factor management remains critical. Tertiary prevention extends to post-LVAD and post-transplant patients, where hypertension, diabetes, obesity, and CKD management remain essential to long-term outcomes.

1. What is the "continuum of prevention" framework, and how does it differ from traditional approaches to heart failure prevention?
Historically, prevention and heart failure management have been treated as separate disciplines—primary prevention handled by preventive cardiologists and treatment managed by heart failure specialists. This joint HFSA/ASPC Scientific Statement reframes prevention as a dynamic, continuous process that spans a patient's entire lifespan, regardless of HF stage or ejection fraction.
The framework maps onto the ACC/AHA HF staging system:
Primary prevention targets Stage A ("at risk") and Stage B ("pre-HF") patients to reduce the burden of incident HF.
Secondary prevention targets Stage C (symptomatic) and Stage D (advanced) patients to reduce the impact of established HF through GDMT optimization and ongoing risk factor management.
Tertiary prevention encompasses risk factor management in patients with LVADs or heart transplants—populations where hypertension, diabetes, and obesity still drive outcomes.
The Central Figure of the statement illustrates that Life's Essential 8 (blood pressure and lipid control, diabetes management, exercise, sleep, smoking cessation, weight management, and diet/nutrition counseling) forms the foundation at every stage, with pharmacologic and device-based therapies layered on top as disease progresses (Figure)
2. How do traditional risk factors drive heart failure, and what should clinicians prioritize?
Hypertension carries the greatest population-attributable risk for HF. In the Framingham Heart Study (N=5,143), HTN was associated with a 2- to 3-fold increased risk of HF, with a population-attributable risk of 39% in men and 59% in women. The SPRINT trial showed a 38% reduction in HF incidence and 25% reduction in the primary composite outcome with intensive BP targets (<120 mm Hg). Not all antihypertensives are equal for HF prevention: the ALLHAT trial showed that amlodipine carried a 38% higher risk and lisinopril a 19% higher risk of incident HF compared with chlorthalidone. The statement recommends prioritizing ACE inhibitors, ARBs, or thiazide diuretics as first-line agents when HF prevention is a goal.
Type 2 diabetes confers a 5-fold risk of HF in women and 2-fold in men. Each 5-year increment in diabetes duration is associated with a 17% increased risk of incident HF. SGLT2 inhibitors have a Class 1 recommendation for HF prevention in patients with T2DM and established CVD or high cardiovascular risk. Finerenone (nonsteroidal MRA) reduced new-onset HF by 32% in the FIGARO-DKD trial among patients with T2DM and CKD. GLP-1 receptor agonists reduce CV events in patients with T2DM and ASCVD and are recommended in current guidelines.
Obesity independently leads to myocardial dysfunction through the leptin-aldosterone-neprilysin framework, ectopic fat deposition, and neurohormonal dysregulation. The SELECT trial demonstrated that semaglutide reduced HF composite endpoint events (HR 0.84; 95% CI 0.74–0.97) in patients with obesity and established CVD without T2DM. Women with obesity are at highest risk for HFpEF, while men with obesity are at highest risk for HFrEF.
Chronic kidney disease with albuminuria is deliberately included as a traditional risk factor in this statement. Albuminuria confers a 2- to 3-fold increased risk of incident HF. UACR screening is recommended for patients with T2DM and those at risk for CKD.
3. How can risk stratification tools and biomarkers be used to identify patients on the trajectory toward heart failure?
Natriuretic peptides (BNP/NT-proBNP): The ACC/AHA/HFSA guidelines give a Class IIa recommendation for BNP or NT-proBNP screening in patients at risk for HF. Even modestly elevated levels (BNP >30 ng/L or NT-proBNP >125 ng/L) are associated with heightened risk for progression to symptomatic HF. In the ARIC study, incorporating NT-proBNP reclassified 20% of older adults without HF into Stage B. Factors that affect interpretation include age, sex, obesity (lower values), and CKD (higher values).
High-sensitivity cardiac troponin (hs-cTn): Concentrations above the 99th percentile are now included in the definition of Stage B HF. Troponin testing may complement natriuretic peptides, particularly when BNP/NT-proBNP values are ambiguous.
Risk scores: The PCP-HF equation predicts 10-year HF risk using traditional risk factors plus QRS duration. The AHA PREVENT score incorporates HF risk calculation and includes markers of kidney function (albuminuria, eGFR), though it may underestimate risk in men and Black adults. The CKM syndrome staging framework (Stages 0–4) provides a holistic approach to assessing systemic cardiovascular-kidney-metabolic risk.
4. What are the key nontraditional risk factors and cross-cutting themes in heart failure prevention?
Genetics: Pathogenic cardiomyopathy variants exist in ~1 in 200 individuals in the general population. The HFSA and ACMG recommend cascade testing to identify at-risk family members. Polygenic risk scores for dilated cardiomyopathy show a 3.8-fold risk for DCM in the top 10th percentile compared with the median.
Sex-specific considerations: Women have 2.8 times the odds of developing HFpEF, while men have similarly increased odds of HFrEF. A complete obstetric/gynecologic history is essential—preeclampsia is associated with a 4-fold increased risk of HF. Peripartum cardiomyopathy requires intentional screening in high-risk populations.
Cardiotoxic exposures: Clinicians should be aware of medications that cause direct myocardial toxicity (e.g., anthracyclines, trastuzumab, tyrosine kinase inhibitors). A team-based approach with pharmacists can help optimize medication selection and risk factor modification.
Social determinants of health: Environmental exposures (air pollution, arsenic, lead, cadmium), food insecurity, financial instability, and limited healthcare access contribute to HF risk and progression. Equity-focused,...
