Precision Medicine and Cardiovascular Health: Insights from Mendelian Randomization Analyses

Area of Science:

• Epidemiology
• Genetics
• Cardiovascular Medicine

Background:

• Cardiovascular disease (CVD) is a leading global cause of mortality, responsible for approximately 17.9 million deaths annually.
• Extensive research focuses on CVD prevention and treatment strategies.
• Mendelian randomization (MR) analyses are increasingly utilized in CVD research.

Purpose of the Study:

• To critically examine existing cardiovascular disease (CVD) literature.
• To specifically highlight the contribution of Mendelian randomization (MR) analyses in CVD research.
• To assess the agreement of research findings across different study designs using a triangulation framework.

Main Methods:

• Systematic review of cardiovascular disease (CVD) literature.
• Application of a triangulation framework to compare findings from studies with differing designs.
• Emphasis on Mendelian randomization (MR) analyses to assess causality.

Main Results:

• Consistent findings across diverse study designs, when subject to non-overlapping biases, provide robust causal evidence for CVD risk factors.
• The triangulation approach reveals emerging patterns in research findings.
• Identified risk factors show potential for precision medicine and novel interventions.

Conclusions:

• Triangulating evidence from various study designs, including Mendelian randomization, strengthens causal inference in cardiovascular disease (CVD) research.
• Consistent findings across methodologies enhance the reliability of identified CVD risk factors.
• This approach supports the development of targeted precision medicine strategies and novel interventions for CVD.
