BACKGROUND Carotid intima media thickness reflects ongoing atherosclerosis in the body and can be measured by B-mode ultrasound. It is found to be a risk factor for cardiovascular diseases. Our study intends to find association of carotid intima media thickness with acute ischaemic stroke. Objectives-To study the association between common carotid artery intima media thickness in patients with acute ischaemic stroke. To study the pattern between carotid intima media thickness and subtypes of ischaemic stroke. To study the pattern between carotid intima media thickness and size of infarct.
MATERIALS AND METHODSThe study design was a case control study. After getting ethical clearance, 42 cases and 42 controls satisfying the inclusion criteria were enrolled in the study. The data on demographic characteristics, smoking and cardiovascular risk factors were collected a s a structured questionnaire. B Mode ultrasound Doppler of both common carotid arteries with carotid intima media thickness measurement was done for all participants in the study. Data analysis was done by SPSS software. Tests of significance were done to find association between CIMT and acute ischaemic stroke, subtypes of brain infarction, while scattered plot for assessing size of infarct.
RESULTSCarotid plaques were present in 40.5% of cases and 14.3% of controls. The mean carotid intima media thickness in the present study is 0.90 ± 0.1 among cases and 0.80 ± 0.1 among controls (p= 0.001). The risk for stroke was 57.1% among cases and 23.8% among controls (p= 0.002). Among infarct subtypes 52.3% had PACIs, 23.8% had LACIs, 16.6% had POCIs and 7% had TACIs. CIMT > 0.9 mm was found in 68.5% of PACI, 66.6% of TACI, 14.2% of POCI and 60% of LACI (p= 0.09). There was no correlation between CIMT and size of infarct (r= 0.132, p= 0.406).
CONCLUSIONThere was significant association between CIMT and acute ischaemic stroke. No association was found between CIMT and brain infarction subtypes. No correlation was found between CIMT and size of infarct.

Evolution Med. Dent. Sci. 2018;7(07):914-918, DOI: 10.14260/jemds/2018/208 BACKGROUND Currently, ischaemic heart disease and stroke are the leading causes of mortality worldwide. The incidence of stroke increases with increasing age and with the growing elderly population worldwide the number of patients with stroke are likely to increase. Developing countries like India are facing a double burden of communicable and non-communicable diseases. Stroke is one of the leading causes of death and disability in India. Stroke is generally defined as sudden or rapidly developing clinical signs of focal disturbance of cerebral function lasting more than 24 hours or leading to death with no apparent cause other than vascular origin.
