Insights
High homocysteine (Hcy) levels correlate with carotid intima-medial thickening (CIMT) in stroke patients. This finding suggests Hcy may help predict atherothrombotic events.
Area of Science:
- Neurology
- Cardiovascular Medicine
- Biochemistry
Background:
- Stroke is a leading cause of disability and mortality.
- Carotid intima-medial thickness (CIMT) is an indicator of atherosclerosis.
- Homocysteine (Hcy) is an amino acid linked to cardiovascular disease.
Purpose of the Study:
- To investigate the correlation between serum homocysteine levels and CIMT in patients with acute anterior circulation strokes.
- To determine if Hcy can serve as a predictor of atherothrombotic events.
Main Methods:
- A study of 100 consecutive acute anterior circulation stroke patients.
- Measurement of fasting serum homocysteine levels within 24 hours of admission.
- Carotid Doppler scans to estimate CIMT on both sides.
Main Results:
- A significant positive correlation was found between serum homocysteine levels and CIMT (r = 0.409, p = 0.000).
- Elevated homocysteine levels accounted for 60% of the variation in CIMT after controlling for other risk factors.
Conclusions:
- Serum homocysteine levels are strongly correlated with CIMT.
- Homocysteine may be a valuable biomarker for predicting atherothrombotic events in stroke patients.
Introduction:
The present study aimed to analyse if there is a correlation between carotid intima medial thickening (CIMT) and Hcy in stroke patients.
Methodology:
We studied 100 consecutive cases of acute anterior circulation strokes at St. John's Medical College, Bangalore, India. Fasting serum samples for homocysteine were sent within 24 hours of admission and all patients underwent a carotid Doppler scan and carotid intima-medial thickness (CIMT) was estimated on both sides.
Results:
There was significant correlation between serum homocysteine levels and carotid intima-medial thickness (r = 0.409, p = 0.000). Also after controlling for other possible risk factors it was found that elevations in serum homocysteine levels would cause a variation of 60% in the carotid intima-medial thickening.
Conclusion:
Serum Hcy levels correlate well with CIMT and hence may predict atherothrombotic events.
