Insights
Arterial and valvular calcification predict mortality and coronary heart disease, especially mitral calcification. However, non-calcified plaques in acute coronary syndrome question calcification
Area of Science:
- Cardiology
- Vascular Biology
- Medical Imaging
Background:
- Arterial and valvular calcification are increasingly recognized as indicators of cardiovascular risk.
- Previous studies suggest a link between calcification and adverse cardiovascular outcomes.
Purpose of the Study:
- To review the predictive ability of arterial and valvular calcification for mortality and coronary heart disease.
- To assess the role of calcification in acute coronary syndrome and stroke prediction.
Main Methods:
- Systematic review of existing literature on arterial and valvular calcification.
- Analysis of predictive value across different patient populations (asymptomatic, symptomatic, high-risk).
Main Results:
- Calcification in multiple locations, particularly mitral annular calcification, has an additive effect on predicting mortality and coronary heart disease.
- While calcification presence, extent, and progression associate with cardiovascular events, this association weakens when adjusting for calcification in other arterial beds.
- Culprit plaques in acute coronary syndrome are typically not calcified, questioning the causal role of calcification.
- Carotid and intracranial artery calcification show limited predictive ability for stroke.
Conclusions:
- Arterial and valvular calcification, especially mitral annular calcification, are significant predictors of cardiovascular events and mortality.
- The predictive value of calcification may be confounded by other factors or non-causal, particularly in acute coronary syndromes.
- Calcification's role in stroke prediction is less clear, with limited predictive ability in carotid and intracranial arteries.
Abstract:
A review of the predictive ability of arterial and valvular calcification has shown an additive effect of calcification in more than 1 location in predicting mortality and coronary heart disease, with mitral annual calcification being a particularly strong predictor. In individual arteries and valves there is a clear association between calcification presence, extent and progression and future cardiovascular events and mortality in asymptomatic, symptomatic and high risk patients, although adjustment for calcification in other arterial beds generally renders associations non-significant. Furthermore, in acute coronary syndrome, culprit plaque is normally not calcified. This would tend to reduce the validity of calcification as a predictor and suggest that the association with cardiovascular events and mortality may not be causal. The association with stroke is less clear; carotid and intracranial artery calcification show little predictive ability, with symptomatic plaques tending to be uncalcified.

Overview of the Cardiovascular System
Heart
The heart is the central pump of the cardiovascular system that circulates blood throughout the body. It comprises two atria receiving the blood and two ventricles pumping blood out of the heart. Their rhythmic contractions, called heartbeats, ensure that blood flow remains continuous.

Prediction Intervals
However, the point estimate is most likely not the exact value of the population parameter, but close to it. After calculating point estimates, we construct interval estimates, called confidence intervals or prediction intervals. This prediction interval comprises a range of values unlike the point estimate and is a better predictor of the observed sample value, y.

Regulation of the Cardiovascular System
The regulation of the cardiovascular system involves the autonomic nervous system (ANS), baroreceptors, and chemoreceptors, ensuring that heart rate and blood pressure are appropriately modulated in response to varying physiological demands.
The ANS comprises two main divisions: the sympathetic and parasympathetic nervous systems. The sympathetic nervous system enhances...
