Objective: The aim was to assess the structural and hemodynamic effects of smoking on the common carotid arteries (CCAs) in current smokers from Himachal Pradesh. In addition, it was important to determine any association between smoking duration, frequency, pack-years, and the occurrence of common carotid atherosclerosis. Materials and Methods: The study evaluated 50 current smokers for common carotid intima-media thickness (CIMT), plaque presence, and resistive index (RI) with sonography. The findings were compared with 50 healthy control patients, who had never smoked. Results: A positive association was observed between smoking and an increase in CIMT ( P = .001) and occurrence of plaques ( P = .007), with substantially higher mean CIMT values in smokers above 45 years ( P < .05) in both genders ( P < .05). No difference in overall RI was seen in both groups taken as a whole, while higher RI values ( P < .05) were noticed in smokers exclusively above 60 years. A positive association was noted between smoking frequency, pack-years, and an increase in CIMT, RI, and occurrence of plaques. For every unit increase in the number of pack-years and smoking duration, there was a 0.01 unit increase in CIMT among the current smokers. Conclusion: This research provides evidence that smoking has a structural impact on CIMT while its hemodynamic effect is still unclear.

Introduction: No data regarding the relationship of carotid intima media thickness (IMT) and serum advanced glycation end products (AGEs) levels in patients with rheumatoid arthritis (RA). The aim of this study is to evaluate the association between IMT and serum pentosidine, CML and MGO levels in patients with longstanding RA.Methods: In a cross-sectional study, 80 consecutive RA patients with longstanding disease were included and compared with 30 age and sex-matched healthy controls. IMT was measured using ultrasonography. AGEs such as pentosidine, Ne-carboxymethyllysine (CML) and methylglyoxal (MGO) as an intermediate of glycation, were determined by ELISA.Results: Serum pentosidine, CML and MGO levels were increased in RA patients vs control subjects (P = 0.001; P < 0.001; P < 0.001 respectively). IMT was increased with disease activity of RA (P = 0.004) and was associated with serum pentosidine (r = 0.460, P < 0.001), serum CML (r = 0.549, P < 0.001) and serum MGO (r = 0.658, P < 0.001). Furthermore, in a multiple stepwise regression analysis CML and MGO were independently associated with IMT (b= 0.333, P = 0.007; b = 0.690, P < 0.001, respectively).Conclusion: serum pentosidine, CML and MGO were increased in RA patients and were significantly related to IMT. Serum CML and MGO were independently associated with IMT.

Incense burning, a source of household indoor air pollution, is possible to effect on cardiovascular system. Our study sought to examine the association of long-term exposure to household incense smoke with increased carotid intima-media thickness (CIMT). A cross-sectional study was conducted 132 adults aged ≥35 years. Participants were stratified into 3 groups by their long-term household incense use; nonexposed group, non–daily exposed group, and daily exposed group. A combined mean CIMT (mean difference = 0.04 mm; P < .01) and combined maximum CIMT (mean difference = 0.09 mm; P < .01) in the daily exposed group had greater than the nonexposed group. The mean CIMT and maximum CIMT of the left common carotid artery in the daily exposed group was significantly greater than the nonexposed group ( P < .01). These findings suggest that incense burning inside the house may be a risk factor for cardiovascular disease morbidity and mortality.

Background: IMT assessment as a non-invasive imaging test is quite widely used especially among RA patients, the clinical applications of using such knowledge is scarce, hence study was conducted to compare the carotid artery intima-media thickness (CIMT) in patients with rheumatoid arthritis (RA) with healthy controls also to study the correlation between duration of rheumatoid arthritis, the activity of rheumatoid arthritis and other factors influencing (CIMT).Methods: In analytical cross-sectional study, of 80 participants of RA and 40 healthy controls, “DAS28” was used to assess disease activity.  Carotid intima-media thickness assessed using carotid ultrasonography.Results: Mean age of the cases and controls was 43.9 and 44.38 years. Subjects with duration of disease <2 years, to 5 years and >5 years were 35%, 45% and 20%. The mean carotid intima-media thickness was 5.61mm in controls, and CIMT was 6.11mm in people below 2 years and 7.08 mm in people between 2 to 5 years and 8.00mm in people above 5 years which was statistically significant. The mean carotid intima-media thickness was 5.61mm controls and 6.86mm in people with low, 7.00mm in people with moderate and 6.95mm in people with high disease activity, which was statistically significant.Conclusions: Study findings revealed risk of increase in carotid intima-media thickness higher among RA patients in the later stages and can increase the patients’ susceptibility to cardiovascular events. The factors showing strong association with intimal medial thickness were the age and symptoms duration.

ABSTRACT Context: Carotid intima-media thickness (CIMT) and apolipoproteins have been found as a risk factor for ischemic stroke . Objective: The objective was to study the carotid intima-media thickness, apolipoproteins, and their relation in patients of ischemic stroke in central rural India. Settings and Design: A cross-sectional study was performed in a rural hospital in central India. Materials and Methods: In all patients of ischemic stroke proven by computerized tomography (CT), CIMT, apolipoprotein A-I (ApoA-I), and apolipoprotein B(ApoB) were measured. Statistical Analysis Used: We used Student′s t-test to compare means, a chi-square test to compare proportions, and a Mann-Whitney test to compare medians. A P value <0.05 was considered significant. Results: The mean age of our study population (N = 106) was 61 years. The mean CIMT was 0.83 mm ranging from a minimum of 0.45 mm to a maximum of 1.096 mm. Mean CIMT was significantly higher than expected 0.67 values, which was calculated according to the age of the study population. The association of decreased ApoA-I < 100 mg/dl and increased ApoB > 90 mg/dl with CIMT > 0.7 mm was statistically significant with P<0.001. Conclusions: The CIMT in computerized tomography-proven ischemic stroke was significantly higher than expected for the age of the study population. The relation of decreased ApoA-I and increased ApoB with CIMT > 0.7 mm was also statistically significant.
