Abstract :

Background: Carotid intima–media thickness (CIMT) is a simple and inexpensive tool to assess the cumulative effect of atherosclerotic risk factors and is an independent predictor of future cardiovascular (CV) risk. Objectives: This study was aimed to investigate the relationships between prevalent cardiovascular events (myocardial infarction, stroke and peripheral arterial disease) and carotid intima–media thickness (CIMT) in middle–aged and older adults. Material and Methods: It was a cross sectional study conducted in between 1^st Jan 2015 to 31^st December 2015 at Integral Institute of Medical Sciences and Research, Lucknow under Department of Radiology. 200 adult subjects were included with evidence of cardiovascular events (including Myocardial Infarction, stroke and Peripheral Artery Disease) and risk factor status (including hypertension and diabetes), adjudicated based on a review of data collected from hospitalizations and outpatient records. According to the carotid ultrasonography, subjects with maxIMT <0.9 mm were defined as normal, while with maxIMT ≥0.9 mm abnormal. The abnormal group included subjects with wall thickening (0.9 mm≤maxIMT <1.2 mm) and with carotid plaque (localized thickenings protruding into the lumen with maxIMT ≥1.2 mm).Results: Our study included 200 study subjects in which 110 were male and 90 were female. It included middle to elderly population with average age of study subjects 62.5 years. The subjects with prevalent cardiovascular events (including MI, stroke and PAD) have higher mean CIMT and higher abnormal CIMT proportion and the results were statistically significant. Conclusion: In summary the combined measurement of IM shows the best index association with prevalent cardiovascular events like MI, Stroke and PVD.
