Updated ABCs Framework Gives Clinicians a Clearer Path to Prevent Cardiovascular Disease
核心洞察
A new 'State-of-the-Art' review in the American Journal of Preventive Cardiology updates the ABCs framework for CVD prevention, integrating PREVENT™ risk scoring and CKM syndrome management.
The framework recommends using the AHA's PREVENT™ equations, built from data on nearly 6.5 million adults, which estimate 10-year and 30-year cardiovascular risks while incorporating social deprivation indices.
Obesity (搜索) affects more than 40% of U.S. adults and substantially increases CVD risk; the framework recommends GLP-1 receptor agonists for selected individuals with obesity and elevated cardiovascular risk.
A comprehensive update to the ABCs of cardiovascular disease (搜索) (CVD) prevention framework, published as a 'State-of-the-Art' review in the American Journal of Preventive Cardiology, offers clinicians an evidence-based roadmap for translating contemporary prevention guidelines into everyday clinical practice. The framework arrives at a time when CVD remains a major public health concern globally, driven by an alarming rise in risk factors such as obesity (搜索), hypertension (搜索), and diabetes (搜索), compounded by population aging and the obesity epidemic.
The updated framework emphasizes that effective CVD prevention begins with identifying at-risk individuals before symptoms or complications occur, and it provides structured guidance spanning risk assessment, lifestyle modification, timely pharmacotherapy, and personalized clinical care across the lifespan.
Risk Assessment Anchored by PREVENT™ Equations
Central to the updated framework is the recommendation to use the Predicting Risk of Cardiovascular Disease (搜索) Events (PREVENT™) equations developed by the American Heart Association (AHA). Built from data on nearly 6.5 million adults aged 30–79 years, these equations estimate 10-year risks for CVD, atherosclerotic CVD, and heart failure (搜索), as well as 30-year risks in adults up to age 60. Notably, the equations incorporate contemporary risk factors including Cardiovascular-Kidney-Metabolic (CKM) syndrome and the social deprivation index.
Because PREVENT™ estimates are often 40–50% lower than pooled cohort estimates, the authors caution that individualized interpretation remains important to avoid undertreatment in selected patients. Risk estimation should be complemented by evaluating risk enhancers, including elevated lipoprotein(a), high-sensitivity C-reactive protein, persistent low-density lipoprotein cholesterol (搜索) of 160 mg/dL or higher, family history, inflammatory disorders, pregnancy-related complications, cardio-oncologic exposures, and frailty. For individuals with borderline or intermediate risk, coronary artery calcium (CAC) scoring can further refine treatment decisions.
The framework also incorporates Life's Essential 8, promoting a healthy diet, physical activity, adequate sleep, tobacco avoidance, healthy weight, and optimal control of blood pressure, cholesterol, and blood glucose to support lifelong cardiovascular health.
Preventive Pharmacotherapy and Blood Pressure Targets
The updated recommendations outline evidence-based approaches to preventive medications based on individual cardiovascular risk. Aspirin should be considered only for carefully selected adults aged 40–70 years who have elevated cardiovascular risk without a high likelihood of bleeding. Individuals with CAC scores of 100 or higher, particularly 400 or higher, may derive greater benefit from aspirin for primary prevention. For patients with established CVD, antiplatelet therapy should be tailored according to both ischemic and bleeding risks, with dual antiplatelet therapy generally recommended for up to 12 months following percutaneous coronary intervention for acute coronary syndrome.
The framework reinforces strict blood pressure control, targeting levels at or below 130/80 mm Hg through lifestyle modification and medication when indicated. Pharmacological treatment is recommended for high-risk individuals, including those with clinical CVD, chronic kidney disease (搜索), diabetes (搜索), or elevated 10-year PREVENT™ risk, while others should first undergo 3–6 months of lifestyle intervention supported by home monitoring and team-based care.
Addressing Obesity (搜索) and Cholesterol
Obesity (搜索) affects more than 40% of adults in the United States and substantially increases the risk of CVD. The new recommendations indicate that clinical obesity assessment should incorporate BMI, waist circumference, other measures of excess body fat, and evidence of organ dysfunction or functional limitation rather than body weight alone. Clinical evaluation should involve diagnosis for heart failure (搜索), obstructive sleep apnea, metabolic syndrome, hepatic steatosis, venous and thromboembolic complications, and atrial fibrillation (搜索).
Lifestyle modification remains the primary treatment, with a target of achieving greater than 5% weight loss. Selected individuals with obesity (搜索) and elevated cardiovascular risk may also benefit from glucagon-like peptide-1 receptor agonists (搜索), which have demonstrated cardiovascular benefits in addition to weight reduction.
Cholesterol management has evolved toward earlier and more personalized treatment. Lipid profiles should be checked during childhood, around ages 9–11, again at ages 19–21, and at least every five years thereafter. Lipoprotein(a) should be measured at least once during a person's lifetime. Risk-based treatment includes lifestyle modification, statin therapy, and combination lipid-lowering therapies when cholesterol goals are not achieved, with lower low-density lipoprotein cholesterol (搜索) targets recommended for individuals at progressively higher cardiovascular risk.
Lifestyle Modification and Cardiometabolic Health
Sustained lifestyle changes remain central to reducing CVD risk. The framework recommends evaluating tobacco and alcohol use during every clinical visit, as smoking, secondhand smoke exposure, electronic cigarettes, and vaping all contribute to CVD, while excessive alcohol intake promotes inflammation and damages blood vessels. Recommended treatments include nicotine replacement therapy, varenicline, or bupropion for tobacco cessation, and naltrexone or acamprosate for alcohol dependence.
The framework highlights the connection between diabetes (搜索), chronic kidney disease (搜索), metabolic disorders, and cardiovascular health through CKM syndrome. Adults without diabetes risk factors should begin diabetes screening at 35 years of age and repeat testing every three years. In patients with type 2 diabetes, eGFR and UACR should also be assessed to identify kidney involvement. Management emphasizes Mediterranean, DASH, and plant-based diets, calorie reduction, and regular physical activity of at least 150 minutes of moderate or 75 minutes of vigorous exercise weekly, along with resistance training twice a week.
The framework further recommends assessing physical and cognitive function during healthy aging, initiating prompt treatment for stage B pre-heart failure (搜索) and stage C heart failure using guideline-directed medical therapy, and managing atrial fibrillation (搜索) with appropriate anticoagulation and early rhythm-control strategies. Shared decision-making, cardiac rehabilitation, and attention to health-related social needs are highlighted as integral to preventive care across the life course.
As the authors conclude, broader use of the ABCs of CVD Prevention model may improve cardiovascular prevention by supporting consistent clinical decision-making, patient-centered care, and uptake of evidence-based recommendations across diverse clinical settings.
