Insights
This study found that different coronary risk factors are linked to plasminogen activator inhibitor 1 (PAI-1) levels in healthy individuals versus those who have had a heart attack. These factors explain over half the variation in PAI-1 activity.
Area of Science:
- Cardiovascular Disease Research
- Biochemistry
- Medical Science
Background:
- Plasma plasminogen activator inhibitor 1 (PAI-1) is implicated in cardiovascular health.
- The specific coronary risk factors associated with PAI-1 activity require further investigation.
- Understanding these associations is crucial for managing cardiovascular risk.
Purpose of the Study:
- To examine the association between 27 coronary risk factors and plasma PAI-1 activity.
- To compare these associations in healthy individuals and myocardial infarction survivors.
- To identify distinct risk factor profiles for PAI-1 activity in different populations.
Main Methods:
- Cross-sectional study design.
- Inclusion of 24 healthy controls and 22 myocardial infarction survivors.
- Analysis of 27 coronary risk factors including age, anthropometrics (intraabdominal fat), and biochemical analytes (triglyceride, von Willebrand factor).
- Univariate and multiple linear regression analyses were employed.
Main Results:
- In healthy controls, triglyceride and von Willebrand factor were significantly associated with PAI-1 activity (p=0.0002, R(2)=0.55).
- In myocardial infarction survivors, age and intraabdominal adipose tissue were significantly associated with PAI-1 (p=0.0011, R(2)=0.51).
- Coronary risk factors explained over 50% of PAI-1 activity variation in both groups.
Conclusions:
- Healthy individuals and myocardial infarction survivors exhibit different coronary risk factors associated with PAI-1 activity.
- These findings highlight population-specific relationships between risk factors and PAI-1.
- Further research may elucidate targeted interventions based on these distinct associations.
Abstract:
Because only some coronary risk factors have been evaluated for an association with plasma plasminogen activator inhibitor 1 (PAI-1) activity, this cross-sectional study examined the association between 27 coronary risk factors and PAI-1 in 24 healthy persons without coronary heart disease (control persons) and 22 patients who had survived myocardial infarction (cases). The coronary risk factors included major coronary risk factors such as age, anthropometric measures such as intraabdominal fat, and biochemical analytes such as serum concentration of triglyceride and plasma von Willebrand factor activity. The associations were analyzed in univariate and multiple linear regression analyses. For the control persons, triglyceride and von Willebrand factor were significantly associated with PAI-1 activity (p=0.0002, R(2)=0.55). In contrast for the 24 cases, age and intraabdominal adipose tissue were significantly associated with PAI-1 (p=0.0011, R(2)=0.51). Coronary risk factors explained more than half the variation of PAI-1 activity for both study groups. However, healthy persons and patients with previous myocardial infarction differed regarding coronary risk factors associated with PAI-1.
