Insights
Cardiovascular risk assessment faces challenges due to combined endpoints and inaccurate event verification. Distinguishing between statin-sensitive and statin-insensitive risks may refine future cardiovascular disease prediction.
Area of Science:
- Cardiovascular Research
- Risk Assessment
- Epidemiology
Background:
- Current cardiovascular risk assessment practices combine diverse vascular events and employ potentially inaccurate verification methods.
- Overlapping pathophysiological pathways of traditional risk factors (hypertension, obesity, diabetes) complicate accurate risk evaluation.
- Establishing causality for cardiovascular disease is challenging, exemplified by LDL cholesterol modification and statin pleiotropic effects.
Purpose of the Study:
- To identify controversial issues in cardiovascular research and risk assessment.
- To discuss unresolved issues concerning established and emerging cardiovascular risk factors.
- To propose alternative frameworks for understanding cardiovascular risk, such as statin-sensitive and statin-insensitive risk.
Main Methods:
- Review of general aspects of risk factor evaluation.
- Discussion of unresolved issues in established and emerging risk factors.
- Evaluation of future prospects for novel risk factors including CRP, homocysteine, ADMA, oxLDL, and isoprostanes.
Main Results:
- Inaccurate verification of vascular events and imprecise definitions of cardiovascular risk blur current estimates.
- Overlapping properties of traditional risk factors present challenges in risk assessment.
- The review highlights the need to consider statin-sensitive and statin-insensitive cardiovascular risk.
Conclusions:
- Ambiguous terminology and varying definitions of cardiovascular risk contribute to controversial issues.
- Emerging risk factors and evolving lifestyle/treatment patterns necessitate a re-evaluation of the risk factor hierarchy.
- Future cardiovascular risk assessment may require a more nuanced approach beyond traditional metrics.
Abstract:
With the aim of identifying areas that may deserve some further thinking the present review deliberately points out controversial issues in cardiovascular research and risk assessment. In the first part of the review general aspects are addressed regarding the evaluation of risk factors. A first point of concern is the frequent practice of combining different vascular events and effects in different vascular beds into a single endpoint. Furthermore, verification of vascular events in clinical reality may be surprisingly inaccurate. Problems in risk assessment also arise from overlapping properties (shared pathophysiological pathways) of traditional risk factors like hypertension, obesity and diabetes. In the second part of the review unresolved issues concerning selected established and emerging risk factors are discussed. The difficulty of establishing causality in cardiovascular disease is addressed, using modification of LDL cholesterol and accumulating evidence for pleiotropic effects of the LDL cholesterol-lowering statins as an example. As an alternative or supplement to the notion of LDL-related cardiovascular risk it is proposed to distinguish between statin-sensitive and statin-insensitive cardiovascular risk. Finally the future prospects of selected new and emerging risk factors like CRP, homocysteine, asymmetrical dimethylarginine (ADMA), oxLDL, and isoprostanes are evaluated. In summary, imprecise terminology and varying definitions of "cardiovascular risk" may lead to a considerable blurring of our current risk estimates, which may also explain some presently controversial issues. With several new risk factors and substantial changes in lifestyle and treatment patterns on the horizon major changes in the hierarchy of risk factors may be inevitable.
