RESUMO
BACKGROUND: Coronary computed tomography angiogram (CCTA) is a crucial tool for diagnosing CAD, but its impact on altering preventive medications is not well-documented. This systematic review aimed to compare changes in aspirin and statin therapy following CCTA and functional stress testing in patients with suspected CAD, and in those underwent CCTA when stratified by the presence/absence of plaque. RESULTS: Eight studies involving 42,812 CCTA patients and 64,118 cardiac stress testing patients were analyzed. Compared to functional testing, CCTA led to 66 â% more changes in statin therapy (pooled RR, 95 â% CI [1.28-2.15]) and a 74 â% increase in aspirin prescriptions (pooled RR, 95 â% CI [1.34-2.26]). For medication modifications based on CCTA results, 13 studies (47,112 patients with statin data) and 11 studies (12,089 patients with aspirin data) were included. Patients with any plaque on CCTA were five times more likely to use or intensify statins compared to those without CAD (pooled RR, 5.40, 95 â% CI [4.16-7.00]). Significant heterogeneity remained, which decreased when stratified by diabetes rates. Aspirin use increased eightfold after plaque detection (pooled RR, 8.94 [95 â% CI, 4.21-19.01]), especially with obstructive plaque findings (pooled RR, 9.41, 95 â% CI [2.80-39.02]). CONCLUSION: In conclusion, CCTA resulted in higher changes in statin and aspirin therapy compared to cardiac stress testing. Detection of plaque by CCTA significantly increased statin and aspirin therapy.

BACKGROUND: The use of the coronary artery calcium score to aid cardiovascular risk stratification may be a more cost-effective tool than the conventional strategy. OBJECTIVES: Evaluation of the cost-effectiveness of the use of the calcium score in therapeutic guidance for primary cardiovascular prevention. METHODS: A microsimulation model to assess the clinical and economic consequences of atherosclerotic cardiovascular disease, comparing the prevention strategy using the calcium score and the conventional strategy. RESULTS: The results obtained demonstrated a better cost-effectiveness of the therapeutic strategy guided by the calcium score, by reducing incremental costs and increasing quality-adjusted life years (QALY), which corresponds, in number, to improving the quality of life of the individual. CONCLUSIONS: The use of the coronary artery calcium score proved to be more cost-effective than the conventional strategy, both in terms of cost and QALY, in most of the scenarios studied.

OBJETIVOS: Avaliação da custo-efetividade do emprego do escore de cálcio na orientação terapêutica para a prevenção primária cardiovascular. MÉTODOS: Modelo de microssimulação para avaliar as consequências clínicas e econômicas da doença cardiovascular aterosclerótica, comparando-se a estratégia de prevenção pelo uso do escore de cálcio e a estratégia convencional. RESULTADOS: Resultados obtidos demonstram melhor custo-efetividade da estratégia terapêutica guiada pelo escore de cálcio, por meio da redução do custo incremental, e aumento nos anos de vida ajustados por qualidade (QALY), que corresponde, em número, ao benefício incorporado à qualidade de vida do indivíduo. CONCLUSÕES: O emprego do escore de cálcio mostrou-se mais custo-efetivo que a estratégia convencional tanto em custo como em QALY, na maioria dos cenários estudados.

RESUMO
PURPOSE OF REVIEW: This review considers the framework of high-risk vs. population approaches as proposed in the Rose's axiom within the context of cardiovascular diseases, including its benefits and limitations. We also contextualize the use of precision medicine in primary prevention therapy and contrast that with population approach. RECENT FINDINGS: Although the high-risk strategy aims at individualized care, the complexity of pharmacologic regimens and other limitations reduces its real-life impact. On the other hand, broad population strategies include treatment of a substantial number of low-risk individuals who are unlikely to benefit from treatment. The use of additional strategies to identify those low-risk individuals, instead of targeting at identifying the high-risk population, is and alternative strategy to be considered. Evidence of the potential use of coronary artery calcium score and polypills for this strategy is discussed. A more targeted population approach to primary prevention in cardiovascular diseases with the use of polypills and coronary artery calcium score might be considered in a structured mass-strategy approach to risk reduction.
