Correlation between cotinine urinary levels & cardiovascular autonomic function tests among smokeless tobacco chewers: A cross-sectional study.

Background & Objectives: Cardiovascular disease (CVD), the leading cause of death worldwide is responsible for over 17 million deaths globally, of which 10 per cent deaths have been expected due to consumption of tobacco. The association between CVD and chewing of tobacco is limited and remains arguable. The aim of this study was to find out the correlation between urinary cotinine level and cardiovascular autonomic function tests of tobacco chewers.
