Background: The objective of this study was to find out relation ship and effects of cigarette smoking on blood pressure, BMI, haemoglobin and haematocrit in coronary heart disease patients. Methods: A total of one hundred and fifty subjects were included in the study. Thirty out of these were control subjects showing no signs or symptoms of coronary heart disease while the rest one hundred and twenty belonged to various categories of coronary heart disease patients. They were further subdivided on the basis of presence or absence of the major five risk factors. Results: The mean age of subgroup with stable and unstable angina was significantly (p<0.05) higher than the mean age of control group. The mean age group of acute myocardial infarction and old myocardial infarction shows no significant difference as compared to the control group. No significant difference was found when the mean body mass indices of these groups were compared to that of the control group. Also no significant difference was found when the mean systolic blood pressures of these groups were compared to that of the control group. Conclusion: It is concluded from the study that there is no significant statistical difference between the smokers and the control group in terms of haemoglobin, haematocrit, and serum blood glucose, BMI, systolic and diastolic blood pressure in stable angina, unstable angina, acute myocardial infarction and old myocardial infarction patients.
