Background: Traditional cardiovascular risk factors, such as age, male sex, hypertension, diabetes mellitus, atrial fibrillation, and dyslipidemia, are associated with ischemic stroke. However, a significant fraction of strokes is still considered to be cryptogenic. Cryptogenic strokes make up roughly 40% of all ischemic stroke cases among stroke patients under the age of 55, highlighting the potential significance of additional, probably unidentified risk factors.

Objectives: To study the significance of lipoprotein (a) as a risk factor for acute ischaemic stroke with its levels in patients of different ages and sex.

Design: single center, cross-sectional, open hospital-based, observational study

Material Methods: 100 patients with acute ischaemic stroke taken who were >18 years of age and s. lipoprotein(a) levels were done. These levels were correlated with age, gender, and conventional risk factors like hypertension, smoking, and diabetes.

Results: In our study out of 100 81% of patients had abnormal lipoprotein(a) levels. The mean lp(a) levels were more in the younger age group [<55yr is 53.34 + 24.06 mg/dl and in >55yr is 45.93 + 24.19 mg/dl] and male sex but they were statistically insignificant.
