Comparison of creatine kinase-MB, troponin-I, troponin-T, Triiodothyronine, Thyroxine, Apoprotein-B and homocysteine between non-smokers, smokers at high altitudes, and smokers at sea level

Earlier diagnosis of heart disease can occur via awareness of biochemical changes. Keeping this in view, we wanted to determine if there was any difference between biochemical heart parameters between non-smokers (the control group), smokers who live at a high altitude, or smokers who live at sea level. There were 180 participants categorised into three groups, A, B, and C, depending upon their smoking/non-smoking classification, or distance from sea level. Blood samples were taken as per requirements to check levels of creatine kinase-MB, troponin-I, troponin-T, Triiodothyronine (T3), Thyroxine (T4), Apolipoprotein B (apo-B), and homocysteine, and subjected to enzyme-linked immunoassay (ELISA) investigations. Creatine kinase-MB, troponin-I, troponin-T, T3, thyroxine, apoprotein-B, and homocysteine all exhibited a noteworthy difference (p≤0.01) when compared between non-smokers and smokers (either at a high altitude or sea level), but only troponin I and T3 showed a noteworthy difference when compared between smokers at a high altitude versus at sea level (p≤0.01) as follows: Creatine kinase-MB, p=0.434; troponin-I, troponin-T, p=0.208; T3, p≤0.01; thyroxine, p=0.190; apoprotein-B, p=0.008; and homocysteine, p=0.039. It has been found that significant differences exist between smokers and non-smokers regarding cardiovascular (CV) pathology, whether the person resides at a high altitude or sea level. However, additional studies should be performed to find the correlation between smokers at a high altitude versus and smokers at sea level, which can change the treatment methods at high altitudes and pave the way for finding new medicines.
