Global Study Reveals Alarming Gaps in Cardiac Drug Use for Secondary Prevention
A groundbreaking study published in JACC, the flagship magazine of the American College of Cardiology, has uncovered notable disparities in the use of prescription drugs for secondary prevention of cardiovascular disease (CVD) across 17 countries. Spanning over 12 years, the research highlights a troubling trend: despite the proven efficacy of these medications, their utilization remains alarmingly low and, in many cases, declines over time.
The study, which observed patients wiht cardiovascular problems from diverse economic backgrounds, found that the use of at least one drug for secondary prevention started at 41.3% during the initial visit, peaked at 43.1%, and then dropped to 31.3% by the final visit. This decline was consistent across most income groups, with the exception of medium-high-income countries, where usage increased from 55% to 61.1%.
High-income countries, while initially showing higher drug utilization rates, experienced a decline from 88.8% to 77.3%. Medium-low-income countries saw a sharp drop from 29.5% to 13.4%, while low-income countries, despite a temporary peak of 47.3%, ultimately fell to 27.5%.
perhaps most concerning is the finding that the use of three or more classes of proven drugs for secondary prevention was “substantially lower than necessary to protect themselves from new cardiovascular events in all the countries examined.” This gap underscores a critical need for improved access and adherence to life-saving medications worldwide.
Key Findings at a Glance
| Income Level | initial Use (%) | Peak use (%) | Final Use (%) |
|————————–|———————|——————|——————-|
| High-Income Countries | 88.8 | 88.8 | 77.3 |
| Medium-high Income | 55.0 | 61.1 | 61.1 |
| Medium-low Income | 29.5 | 31.7 | 13.4 |
| Low-Income Countries | 20.8 | 47.3 | 27.5 |
The study’s findings raise urgent questions about the barriers to effective CVD management, especially in lower-income nations. Factors such as cost, accessibility, and awareness may play a significant role in these disparities.
As the global burden of cardiovascular disease continues to rise, this research serves as a stark reminder of the need for targeted interventions to ensure that all patients, nonetheless of their economic status, have access to the medications they need to prevent life-threatening events.

Global Study Reveals Alarming Gaps in Cardiac Drug Use for Secondary Prevention: Expert Insights
A recent study published in JACC, teh flagship magazine of the American College of Cardiology, has highlighted important disparities in the use of prescription drugs for secondary prevention of cardiovascular disease (CVD) across 17 countries over 12 years. the study found that while these medications are proven to save lives, their utilization remains alarmingly low and often declines over time, notably in lower-income nations. To understand the implications of these findings and explore potential solutions, we sat down with Dr. Emily Carter, a renowned cardiologist and expert in global cardiovascular health.
The State of Global Cardiac Drug Use
Senior Editor: Dr. Carter, the study revealed that the use of cardiac medications for secondary prevention is declining in most countries. What do you think is driving this trend?
dr. Emily Carter: The decline is concerning, but not entirely surprising. several factors contribute to this trend. Cost is a significant barrier, especially in low- and medium-income countries where patients frequently enough struggle to afford lifelong medications. Accessibility is another issue—manny regions lack well-stocked pharmacies or healthcare facilities. Additionally, there’s a lack of awareness among patients and even some healthcare providers about the critical importance of these drugs in preventing recurrent cardiovascular events. adherence is a challenge—patients may stop taking their medications due to side effects or because they feel better, not realizing the long-term risks.
Disparities Across Income Groups
Senior Editor: The study shows stark differences in drug use between high-income and low-income countries. as a notable example, high-income countries started at 88.8% usage but dropped to 77.3%, while low-income countries peaked at 47.3% but fell to 27.5%. Why do you think this gap exists?
Dr. Emily Carter: The gap reflects systemic inequalities in healthcare infrastructure and resources. High-income countries typically have better healthcare systems,more affordable medications,and higher patient education levels. In contrast, low-income countries face challenges like limited healthcare funding, inadequate supply chains, and a higher burden of competing health issues, such as infectious diseases. Additionally, cultural and social factors may influence medication use—some patients may rely more on customary remedies or lack trust in modern medical treatments.
Barriers to Effective CVD Management
Senior Editor: The study mentions cost, accessibility, and awareness as key barriers. Could you elaborate on these and suggest ways to address them?
Dr. Emily Carter: Absolutely. Cost is perhaps the most immediate barrier. Governments and NGOs can help by subsidizing essential medications or implementing global healthcare programs. Accessibility can be improved by strengthening supply chains and training healthcare workers in underserved areas. Awareness campaigns are also crucial—educating patients about the benefits of adherence and training healthcare providers to emphasize long-term prevention could make a significant difference. Telemedicine and mobile health initiatives could also bridge gaps in care.
The Role of multi-Drug Therapy
Senior Editor: The study found that the use of three or more proven drug classes was “substantially lower then necessary” globally. Why is multi-drug therapy important, and what can be done to improve it’s adoption?
Dr.Emily Carter: Multi-drug therapy is critical as different medications target different mechanisms of cardiovascular disease. For example, beta-blockers reduce heart rate and blood pressure, statins lower cholesterol, and antiplatelet drugs prevent blood clots. Together, they substantially reduce the risk of recurrent events. However, using multiple drugs increases complexity and cost, which can deter patients. Simplifying regimens, developing combination pills, and providing patient support programs can definitely help improve adherence. Policymakers also need to prioritize making these medications more affordable and accessible.
Global Implications and the Path Forward
Senior Editor: With cardiovascular disease being a leading cause of death worldwide, what can the global health community do to address these disparities?
Dr. Emily Carter: The first step is recognizing that this is a global issue requiring coordinated efforts. Governments, NGOs, and the private sector need to collaborate to improve healthcare infrastructure, reduce medication costs, and launch education campaigns. International organizations like the World Health Organization (WHO) can play a pivotal role by setting guidelines and supporting low-income countries. Additionally, research into innovative solutions, such as low-cost generics or digital health tools, is essential. Ultimately, we need to ensure that life-saving medications are accessible to everyone, irrespective of their economic status.
Conclusion
Senior Editor: Thank you, Dr. Carter,for your insights.To summarize, the study underscores the urgent need for global action to improve access to and adherence of cardiac medications. Addressing cost, accessibility, and awareness barriers, along with promoting multi-drug therapy, could save countless lives and reduce the burden of cardiovascular disease worldwide.
Dr. Emily Carter: Exactly. It’s a challenge, but with collective effort, we can make significant progress in ensuring that all patients receive the care they need.
