Insights
Sudden cardiac death (SCD) is a major cause of mortality. This review updates non-invasive diagnostic tools to predict life-threatening arrhythmias and SCD risk in patients and healthy individuals.
Area of Science:
- Cardiology
- Medical Diagnostics
- Public Health
Background:
- Cardiovascular diseases are a leading global cause of death, with sudden cardiac death (SCD) accounting for approximately 25% of these fatalities.
- Current diagnostic strategies for SCD prevention primarily target patients with known cardiovascular diseases and often lack sufficient positive predictive accuracy.
- There is a critical need for improved risk stratification parameters, especially for identifying SCD risk in seemingly healthy individuals.
Purpose of the Study:
- To provide an updated overview of non-invasive diagnostic features for identifying individuals at elevated risk of malignant ventricular arrhythmias and SCD.
- To address the limitations of existing diagnostic tools and the need for better risk assessment in both patient and general populations.
Main Methods:
- This review synthesizes current literature on non-invasive diagnostic methods relevant to SCD risk.
- Focus is placed on features that aid in stratifying risk for malignant ventricular arrhythmias.
Main Results:
- The review highlights various non-invasive parameters that can assist in predicting SCD risk.
- Emphasis is placed on the limitations of current predictive accuracy and the ongoing search for more effective markers.
Conclusions:
- Accurate prediction of SCD remains a significant challenge in cardiovascular medicine.
- Further research and development of non-invasive diagnostic tools are essential for improving patient outcomes and public health strategies related to sudden cardiac death.
Abstract:
Cardiovascular diseases remain among the leading causes of death worldwide and sudden cardiac death (SCD) accounts for ~25% of these deaths. Despite its epidemiologic relevance, there are very few diagnostic strategies available useful to prevent SCD mainly focused on patients already affected by specific cardiovascular diseases. Unfortunately, most of these parameters exhibit poor positive predictive accuracy. Moreover, there is also a need to identify parameters to stratify the risk of SCD among otherwise healthy subjects. This review aims to provide an update on the most relevant non-invasive diagnostic features to identify patients at higher risk of developing malignant ventricular arrhythmias and SCD.
