Obesity is a growing global epidemic with significant implications for cardiovascular diseases (CVD). It couples as an independent risk factor and driver for multiple pathways leading to CVDs. Here we examine obesity’s impact on CVD and propose actionable strategies. Data from the NCD Risk Factor Collaboration (NCD-RisC), Global Burden of Disease (GBD) survey, and regional health surveys databases were used. We examined trends in obesity prevalence and CVD mortality attributable to high body mass index (BMI), disaggregated by sex, geography, socioeconomic status, and urban–rural residence. Evidence from national policy initiatives and clinical management guidelines was also reviewed. As of 2022, over 1 billion people globally were living with obesity. Since 1990 the age-standardised obesity prevalence has doubled among women (from 8.8% to 18.5%) and tripled among men (from 4.8% to 14%). Globally, the number of annual CVD deaths attributable to high BMI (25 kg/m2 or over) more than doubled between 1990 and 2021, reaching 1.9 million in 2021. Reducing global obesity to 2019 levels could save an estimated US$2.2 trillion annually by 2060. Positive steps have been made in recent years, with the implementation of several global, national and local initiatives that show promise in tackling obesity and CVDs, in addition to the emergence of potentially game-changing medical interventions, such as glucagon-like peptide-1 receptor agonists (GLP-1RAs). Yet, to tackle obesity and associated CVD, there is a need for a holistic approach across clinical and public health interventions that accounts for the multiple determinants of obesity. We recommend the implementation of evidence-based, cost-effective public health measures, and the incorporation of obesity-specific recommendations into cardiovascular guidelines. Addressing the global cardiovascular crisis linked to obesity will require coordinated efforts from policymakers, healthcare systems, and global health organisations.
