Insights
Comparing new guidelines for atherosclerotic cardiovascular disease prevention reveals differences in risk stratification. The Brazilian model shows higher sensitivity, while the American model may overestimate risk, highlighting areas for further research.
Area of Science:
- Public Health
- Cardiology
- Preventive Medicine
Background:
- Atherosclerotic cardiovascular disease is a leading cause of mortality globally and in Brazil.
- Effective control strategies for dyslipidemia and atherosclerosis are crucial public health priorities.
- Recent publication of three major guidelines offers a timely opportunity for comparative analysis.
Purpose of the Study:
- To compare three recently published international guidelines on dyslipidemia and atherosclerosis prevention.
- To identify advancements and controversial aspects in current preventive strategies.
- To discuss the efficiency and limitations of early diagnosis in managing atherosclerotic disease.
Main Methods:
- Comparative analysis of Brazilian, English, and American guidelines for dyslipidemia and atherosclerosis prevention.
- Review of current literature on early diagnosis and screening strategies for atherosclerotic cardiovascular disease.
- Identification of key differences in risk stratification and diagnostic criteria.
Main Results:
- The Brazilian model demonstrates greater sensitivity in risk assessment.
- The English model does not incorporate risk stratification.
- The American model may potentially overestimate cardiovascular risk.
- Concerns exist regarding the transformation of risk into disease and overdiagnosis.
Conclusions:
- Comparative analysis of guidelines reveals significant differences in approaches to atherosclerotic cardiovascular disease prevention.
- Further research is needed to address controversial aspects, including screening limitations and overdiagnosis.
- Optimizing early diagnosis and risk stratification remains critical for effective disease management.
Abstract:
Control of atherosclerotic cardiovascular disease - a highly prevalent condition and one of the main causes of mortality in Brazil and worldwide - is a recurrent subject of great interest for public health. Recently, three new guidelines on dyslipidemia and atherosclerosis prevention have been published. The close release of these important publications is a good opportunity for comparison: the Brazilian model has greater sensitivity, the English model does not work with risk stratification, and the American model may be overestimating the risk. This will allow reflection on current progress and identification of controversial aspects which still require further research and debate. It is also an opportunity to discuss issues related to early diagnosis and its efficiency as a preventive strategy for atherosclerotic disease: the transformation of risk into disease, the gradual reduction of cut-off points, the limitations of the screening strategy, and the problem of overdiagnosis. RESUMO O controle da doença cardiovascular aterosclerótica - morbidade de alta prevalência e uma das principais causas de mortalidade no Brasil e no mundo - continua sendo tema de grande interesse para a Saúde Pública. Recentemente, três novas diretrizes sobre dislipidemia e prevenção da aterosclerose foram divulgadas. A convergência no tempo dessas importantes publicações constitui boa oportunidade para sua comparação: o modelo brasileiro tem maior sensibilidade, o inglês não trabalha com risco estratificado e o norte-americano parece estar superestimando o risco.Isso permitirá reflexões acerca dos avanços que já foram alcançados e identificação de aspectos ainda controversos, que seguem exigindo novas pesquisas e debates. É também uma oportunidade para discutir questões relacionadas ao diagnóstico precoce e sua eficiência como estratégia preventiva da doença aterosclerótica: as transformações do risco em doença, a diminuição progressiva de pontos de corte, as insuficiências da estratégia de rastreamento e o problema do sobrediagnóstico.
