Abstract

Deep Vein Thrombosis (DVT) can lead to pulmonary embolism and it is the third most common causes of death in cardiovascular disease after stroke and heart attack. This study aims to determine the frequency of deep venous thrombosis (DVT) in relation to age, gender, and ethnic in Malaysia. A retrospective cohort study was conducted with patients who went for suspected DVT screening in University Malaya Medical Center (UMMC), Kuala Lumpur from 1 January 2016 to 31 December 2019. Colour Doppler ultrasound machine (Philips IU22) was used for the DVT screening. All patients' data were retrieved from the Radiology Information System (RIS) database of UMMC. Only outpatients' data with confirmed DVT were collected. The data were analysed according to age, gender and ethnicity. A total of 474 outpatients with suspected with DVT were enrolled in this study. But, only 167 outpatients were diagnosed with DVT. However, based on inclusion and exclusion criteria, only 151 of outpatients’ data were eligible for analysis according to age. Meanwhile, there were 159 and 155 of outpatients’ data which were eligible for analysing the prevalence of DVT based on gender and ethnicity, respectively. The highest prevalence of DVT was shown by the age group of 65-100 (52.3%). The difference between the eldest and oldest age group was 50.7%. As for gender, the female has a higher frequency than the male by 66.7% with the differences of 33.4%. Among the three main ethnicities in Malaysia, Chinese shows higher frequency (44.5%). The differences between Chinese and Malay ethnic was 4.5 % while 29% between Chinese and Indian ethnic.Older age group have a greater frequency of having DVT among all age groups. Females have a high risk of having DVT compared to male for all studied ethnicity and Chinese ethnic has higher prevalence followed by Malay and India.
