Summary
Atherosclerotic cardiovascular disease is a widespread and costly health issue, particularly affecting older adults. Comprehensive preventive strategies targeting risk factors can mitigate various manifestations and reduce mortality from heart disease and stroke.
Area of Science:
- Cardiology
- Preventive Medicine
- Public Health
Background:
- Cardiovascular disease (CVD) is a leading cause of mortality and morbidity, representing 44% of national deaths.
- Atherosclerotic cardiovascular disease (ASCVD) is increasingly prevalent due to an aging population, with coronary heart disease being a major cause of death.
- ASCVD incurs substantial economic costs, estimated at $259 billion in 1997, and affects the heart, brain, and peripheral arteries.
Purpose of the Study:
- To highlight the generalized nature of atherosclerotic cardiovascular disease and its interconnected clinical manifestations.
- To emphasize the importance of comprehensive preventive measures for both primary and secondary prevention of ASCVD.
- To underscore the role of risk factor modification in preventing diverse atherosclerotic outcomes.
Main Methods:
- Review of epidemiological data on cardiovascular disease prevalence, mortality, and economic burden.
- Analysis of the generalized nature of atherosclerosis and its coexisting clinical manifestations across different arterial territories.
- Examination of meta-analyses of randomized trials on antiplatelet agents for secondary prevention.
Main Results:
- ASCVD is a systemic process, with manifestations in one area increasing the likelihood of others due to shared risk factors.
- Meta-analyses show that low-dose aspirin and antiplatelet agents reduce myocardial infarctions, strokes, and cardiovascular mortality by approximately 25% in patients with existing CVD.
- Correction of risk factors or prevention of one ASCVD outcome is associated with the prevention of other atherosclerotic disease outcomes.
Conclusions:
- Comprehensive preventive measures are crucial for individuals at high risk of initial atherosclerotic events and those with existing disease.
- Preventive strategies targeting major risk factors can address multiple arterial territories simultaneously.
- Implementing unified preventive approaches for ASCVD is essential for healthcare professionals to reduce disease burden and mortality.
