BACKGROUND: @entity453 is now frequently encountered in young adult population. However, being a relatively uncommon entity, not many studies are available in this regard. Therefore, the present study was designed to evaluate the clinical characteristics and angiographic features of @entity1 less than 40 years of age with a history of @entity583 and compare them to @entity1 older than 40 years. METHODS: A total of 281 @entity1 who underwent coronary angiography from April, 2009 to December, 2009, were included in this study. The @entity1 were divided into two groups on the basis of age. Group A included @entity1 40 years of age or younger. Group B included @entity1 older than 40 years. Both the groups were compared with respect to gender, @entity101 , @entity6 and extent and severity of @entity453 as assessed on coronary angiography. RESULTS: Of the total 281 @entity1 , 45 (16%) were < or =40 years old (Group-A) and 236 (84%) were older than 40 years (Group-B). There was no significant difference between the two groups with respect to the risk factors like gender, @entity101 and @entity6 . On coronary angiography, the two groups neither differed in the number of totally occluded vessels, nor in the severity of the culprit lesion. There were only 3 @entity1 in group-A (6.7%) and 5 @entity1 in group-B (2.1%) with normal coronaries (p=NS). Majority (60%) of the @entity1 in group-A had no significant @entity66 while majority (69%) of the @entity1 in group-B had two or more vessels involved (p<0.001 ). As far as the number of lesions in the coronary arteries is concerned, 62.3% @entity1 had 2 or lesser lesions in group-A while 68.6% @entity1 in group-B had three or more lesions (p=0.001). CONCLUSION: These data suggest that in our study, young @entity1 with MI do not have significantly high prevalence of normal coronaries compared to older @entity1 . Young @entity1 are similar to the older @entity1 with respect to severity of CAD. Lesser number of coronaries is involved and there is lesser number of lesions per @entity1 in young @entity1 compared to older ones.
