Community-Wide Heart Health Screenings Reveal Key Risk Factors for Heart Disease

In a groundbreaking community-based initiative, researchers have demonstrated that pop-up cardiovascular screenings held at community pharmacies and large-scale sporting events can effectively identify individuals harboring uncontrolled atherosclerotic cardiovascular disease (ASCVD) risk factors. Published in the Journal of the American College of Cardiology (JACC) and unveiled at the 73rd Annual Scientific Meeting of the Cardiac Society of Australia and New Zealand, this extensive study underscores the potential of decentralized screening modalities to bridge gaps in preventative cardiovascular care.

ASCVD remains the dominant cause of mortality globally, responsible for millions of deaths annually. Despite the prevalence of this pathology, many cases are preventable through early identification and management of modifiable risk factors, such as elevated blood pressure (BP), increased body mass index (BMI), and tobacco use. However, widespread adoption of preventive screenings and comprehensive risk assessment remains suboptimal, particularly in community settings that lack routine engagement with healthcare services.

The present study leverages an innovative approach, employing pop-up health stations located across 311 community pharmacies throughout Australia, supplemented by dedicated screening during an internationally followed cricket tournament. These sites provided contemporaneous assessment opportunities for cardiovascular risk parameters, capitalizing on high public footfall and accessibility. Screenings occurred from December 15, 2023, to January 31, 2024, with pharmacy hours segmented into daytime (pre-5 p.m.) and evening (post-5 p.m.) intervals, enabling granular temporal analyses of participant profiles and risk factor prevalence.

A total of over 76,000 individuals underwent screening during this seven-week initiative, with a significant majority (nearly 90%) assessed in pharmacy settings and the remainder at the cricket matches conducted from December 26-29, 2023. Participants predominantly consisted of men aged 25 to 34, a demographic often underrepresented in traditional health screening programs. Crucially, the study found that approximately 69% of people screened presented with at least one uncontrolled cardiovascular risk factor, a concerning revelation of the burden of unrecognized risk in the community.

Diving deeper into the data, over one-third of participants with recorded blood pressure measurements exhibited values within the hypertensive range, revealing a critical gap in hypertension diagnosis and management. Remarkably, the screening site influenced the predominant risk factors identified. Cricket match attendees showed higher incidences of elevated blood pressure and BMI, yet reported lower smoking rates compared to those screened in pharmacies. This suggests environmental and behavioral differences reflective of screening contexts and population compositions.

One of the study’s pivotal findings relates to healthcare engagement in hypertensive individuals. Nearly half of the persons with elevated BP had not undergone a blood pressure check within the preceding year, and a staggering majority—over 80% of cricket match attendees with hypertension and nearly 70% of pharmacy attendees—were not receiving antihypertensive medication. This discloses a significant opportunity for intervention, given that blood pressure control is a well-established determinant of cardiovascular event risk reduction.

Focusing on rural versus urban pharmacy screenings revealed not only demographic differences but also disparity in cardiovascular risk factor prevalence. Those screened at rural pharmacies were generally older (over 45 years) and reported higher rates of diabetes, another key ASCVD risk enhancer. Rural populations exhibited heightened rates across all measured risk factors, further emphasizing the need for targeted public health strategies addressing geographic healthcare inequities.

Professor Stephen Nicholls, director of the Victorian Heart Institute and senior author of the study, articulated the transformative potential of embedding heart health checks within accessible community venues and popular events. He emphasized that such initiatives are adaptable to diverse populations, capable of targeting groups at elevated risk who often face barriers to traditional healthcare access. By aligning screening efforts with community dynamics, the approach promises to close gaps in early detection, thereby facilitating timely lifestyle modification or pharmacologic intervention to mitigate future cardiovascular events.

The deployment strategy capitalized on the Shane Warne Legacy Health Test initiative, honoring the late Australian cricket legend while harnessing public interest surrounding the international cricket series to promote cardiovascular health awareness. This dual-purpose engagement not only elevated participation rates but also demonstrated the feasibility of integrating health screening with large-scale, culturally resonant events.

Technically, the screening methodology incorporated standard, validated measures of blood pressure, BMI calculation, and smoking status ascertainment, enabling robust risk stratification in a rapid, community-friendly format. The use of pop-up stations allowed flexible deployment and scalability, reducing logistic burdens typically associated with mass screening programs. This adaptability is critical in translating clinical guidelines into actionable public health interventions.

The significant detection of uncontrolled risk factors among relatively young adults highlights the pressing need to redefine conventional paradigms of cardiovascular screening. Whereas current practices often prioritize older or symptomatic individuals, this study advocates for earlier, more widespread engagement, recognizing that subclinical risk accumulates silently and manifests clinically only after substantial vascular compromise.

Moreover, the documented lack of antihypertensive treatment among hypertensive individuals signals systemic failures in linking screening outcomes with longitudinal care pathways. Future program designs must integrate immediate referral mechanisms, electronic health record connectivity, and patient education frameworks to convert screening findings into sustainable therapeutic actions.

This pioneering work, by illustrating the efficacy of community-embedded pop-up screening models, propels the conversation about democratizing preventive cardiovascular health services. The integration of such strategies holds promise for significantly curbing the global ASCVD burden through early detection, risk factor modulation, and equitable healthcare access. Continued research and policy focus are warranted to optimize these interventions and ensure their long-term impact across diverse populations.
