To emphasize the importance of longitudinal urine albumin-to-creatinine ratio (UACR) measurements in cardiovascular disease (CVD) risk assessment, highlighting their role in identifying high-risk individuals.
Key Findings:
Three distinct UACR trajectories were identified: slow rise at low level, slow rise at medium level, and sustained medium to high over 5 years; slow rise at low level, slow rise at medium level, and rapid rise over 10 years.
High-risk UACR trajectories were associated with significantly increased risks of heart failure, atrial fibrillation, and coronary heart disease.
Even participants with normal baseline UACR showed worse outcomes if they had a high-risk trajectory, indicating the need for repeat measurements.
Interpretation:
Longitudinal UACR measurements provide critical prognostic information that single-time-point assessments may overlook, particularly in identifying high-risk individuals and understanding disease progression.
Limitations:
The study's findings may not be generalizable to all populations due to demographic variations, such as age, sex, and ethnicity.
Potential confounding factors, such as comorbidities and lifestyle factors, were not fully addressed, which may influence the associations observed.
Conclusion:
Routine serial UACR measurements can enhance cardiovascular risk stratification and preventive care, especially since albuminuria is treatable, thereby improving patient outcomes.
