Importance of Imaging in Work up of Cardiovascular Diseases by Using Telemedicine in Rural India.

BACKGROUND: Cardiovascular diseases have emerged as an epidemic in India. Telemedicine is a useful tool for sending ECG, x-ray and ultrasound images to telemedicine centre for diagnosis and management of cardiovascular diseases in rural areas as it overcomes the distance barrier. METHODS: National Heart Institute collaborated with Hospital Guide Foundation (HGF) Jewar, Greater Noida for conducting telemedicine sessions. Two hundred patients were analysed during time span of June 2018 to August 2019. Imaging tools like ECG, Chest X- ray and ultrasound were studied besides usual laboratory parameters. RESULTS: Important ECG abnormalities included LVH (10.9%), ischemia (10.1%), LBBB (2.4%), RBBB (3.9%), p- mitrale (1.5%), hyperkalaemia (2.3%) besides normal ECGs (56.2%). Chest x- ray revealed features of COPD (8.3%), cardiomegaly (6.9%), hilar shadows (6.9%), bronchitis (2.7%) and prominent broncho -vascular markings (6.9%). Ultrasound abdomen showed hepatomegaly (23.2%), fatty liver (15.1%), gallstones (2%). bilateral renal stone / left or right renal stone (42.4 %). CONCLUSION: Telecardiology/ Teleradiology are important and useful imaging tools in the diagnosis and treatment of cardiovascular diseases in rural India.

Effects of Tobacco on Biochemical Parameters in Healthy and Type 2 Diabetic Subjects.

Diabetes and tobacco use are two of the largest public health challenges of our time. We aim to investigate the association between the two by comparing biochemical profiles of diabetic tobacco users (TUs) and tobacco nonus-ers (TNUs) to provide insight into the joint effect of tobacco and diabetes on body systems. This case-controlled study included 265 subjects, aged 18-60 yr, from the suburban population of Delhi, India. With the help of a questionnaire, participants are interviewed regarding their history of tobacco use. Results show association of tobacco use with elevated body-mass index, blood glucose levels, and insulin resistance in otherwise healthy and diabetic TUs. Even without previous history of coronary heart disease, total cholesterol and triglycerides are significantly further increased in TUs rather than in TNUs, indicative of initiation of lipid metabolism disorders. Tobacco use is also seen as a cause of oxidant/antioxidant imbalance in the body. Low serum albumin coupled with increased markers of inflammation and globulin levels is an indicator of generalized inflammation caused by tobacco's toxic effects. Creatinine levels are significantly higher in diabetic TUs, posing a threat to nephropathy progression. Evidence sufficiently infers that tobacco activates multiple biological pathways, through which the risk of metabolic disease increases. These factors may work in conjunction to increase risk of certain microvascular and macrovascular complications.

Effect of Cichorium intybus seeds supplementation on the markers of glycemic control, oxidative stress, inflammation, and lipid profile in type 2 diabetes mellitus: A randomized, double-blind placebo study.

Diabetes mellitus is associated with increased levels of inflammation and oxidative stress in patients. The aim of the present study was to test the hypothesis that aqueous extract of Cichorium intybus seeds (AECIS) would have add-on beneficial effect in type 2 diabetes mellitus (T2DM). In this double-blind randomized clinical study, 150 subjects were enrolled to assess the add-on efficacy and safety of AECIS in T2DM patients. The subjects were randomized (1:1) to the AECIS (n = 51) and placebo (n = 49) groups. The subjects in both groups continued to take prescribed doses of metformin. The standardization of AECIS was carried out by liquid chromatography-mass spectrometry and phytochemical analysis. The mean hemoglobin A1c (HbA1c) level in the AECIS and placebo groups at baseline was 8.6% and 8.5%, respectively. Mean values of HbA1c at the end of 12 weeks of intervention were 7.42% in the AECIS group (a reduction of 1.18% from baseline) and 8.4% in the placebo group (mean reduction of 0.1% from baseline). Besides, significant reduction in inflammation, oxidative stress, and hypertriglyceridemia was seen in the AECIS group (p < .05). The study shows for the first time that AECIS supplementation ameliorates the disease progression and it is beneficial as a potential adjunct dietary supplement for the management of T2DM.

Role of Terminalia arjuna Wight and Arn. in the treatment of chronic coronary artery disease from pharmacovigilance point of view.

BACKGROUND AND OBJECTIVES: Terminalia arjuna Wight and Arn. (Arjuna) has been used in indigenous system for the treatment of cardiac ailments since 500 BC. However, there is a lack of vigilance studies during long-term therapy. The present clinical study was planned to examine the long-term safety of Arjuna as an adjunct drug in chronic coronary artery disease (CAD) patients. MATERIALS AND METHODS: During the study period, a total of 35 patients of chronic CAD were enrolled to receive Arjuna bark extract powder (500 mg three times daily) along with conventional drugs. The control group (35 patients) received conventional drugs alone. Hemogram, liver function tests and kidney function tests were done at baseline and then every 6 months until the end of the study. Electrocardiography was done every 6 months and echocardiography was done yearly for left ventricular ejection fraction and regional wall motion abnormalities. Any adverse drug reactions reported by the patients were also recorded. RESULTS: The mean age of patients in test and control groups was 60.88 ± 9.02 and 58.51 ± 12.64 years, respectively. There was a predominance of male patients in both the groups. The patients were observed for duration ranging from 9 months to 4 years and 9 months. Other than baring gastritis and constipation, no other noteworthy adverse effects were reported. No significant difference was found in laboratory value on baseline and end of therapy in both the groups. CONCLUSION: The results of the present study concluded that Arjuna is safe and effective in patients with chronic coronary artery disease.

Cichorium intybus attenuates streptozotocin induced diabetic cardiomyopathy via inhibition of oxidative stress and inflammatory response in rats.

The aim of the present study was to investigate the effects of Cichorium intybus on lipid peroxidation activities of both enzymatic and non-enzymatic antioxidants, inflammatory mediators, myocardial enzymes and histopathology of cardiac tissues in experimental diabetic cardiomyopathy (DCM). DCM was induced by single intraperitoneal injection of streptozotocin (STZ) (40 mg/kg) combined with high energy intake in rats. Seed extract of Cichorium intybus (CIE) (250 mg/kg & 500 mg/kg) was administered orally once a day for 3 weeks. Phytochemical investigations of seed extract revealed presence of some active ingredients such as alkaloids, tannins, saponin, phenols, glycosides, steroids, terpenoids and flavonoids. Seed extract of Cichorium intybus confirmed a significant potency towards restoring the blood glucose, an elevation of the levels of aspartate aminotransferase (AST), lactate dehydrogenase (LDH), superoxide dismutase (SOD), thiobarbituric acid reactive substances (TBARS), blood glutathione (GSH), TNF-α and IL-6 and a reduction in the levels of catalase (CAT) was observed following the STZ treatment. Oxidative stress was accompanied by myocardial degeneration as evidenced by histopathological examination of cardiac tissues. Administration of CIE reduced the lipid peroxides level in heart. Serum levels of AST, GSH, LDH and SOD were brought down to physiological levels by CIE in STZ induced DCM rats. CIE also markedly down-regulated serum TNF-α and IL-6 levels. Catalase that was reduced in serum was brought back to near normal level. The extensive necrotic changes of cardiac tissue by STZ was minimized to normal morphology upon CIE administration. The study demonstrates the cardioprotective effect of CIE via inhibition of oxidative stress and pro-inflammatory cytokines.

Postprandial triglyceride responses and endothelial function in prediabetic first-degree relatives of patients with diabetes.

BACKGROUND: Only a few studies have reported on postprandial lipid responses and endothelial function in prediabetic subjects. None of the study has compared role of familial predisposition in determining postprandial endothelial dysfunction and postprandial hypertriglyceridemia in subjects with prediabetes. OBJECTIVE: The objective was to study the postprandial triglyceride (PPTG) responses and endothelial function in prediabetic first-degree relatives of patients with diabetes. METHODS: Thirty-nine subjects were recruited on the basis of oral glucose tolerance test into 3 groups: group 1, prediabetic subjects who had a first-degree relative with diabetes; group 2, prediabetic subjects without family history of diabetes; and group 3, normal glucose tolerance subjects without family history of diabetes. Oral fat challenge test was performed in all study subjects and PPTG responses were measured up to 8 hours. Postprandial endothelial function after 4 hours of fat challenge was estimated by flow-mediated dilation. RESULTS: Postprandial endothelial dysfunction was greatest in group 1 and significantly higher in group 1 compared with group 2 (P < .001) and group 2 compared with group 3 (P < .001). PPTG responses (TG-AUC, TG-peak, TG-6 hour, and TG-8 hour) were significantly higher in group 1 compared with groups 2 and 3. However, they were similar between groups 2 and 3. Endothelial function showed significant negative correlation with TG-6 hour and TG-8 hour. CONCLUSION: Prediabetic subjects respond to fat challenge with a greater degree of TG response and endothelial dysfunction compared with normal glucose tolerance subjects especially if they have a first-degree relative with diabetes. This may contribute to enhanced cardiovascular risk reported in prediabetic individuals.

Study of adverse drug reactions in patients with diabetes attending a tertiary care hospital in New Delhi, India.

The present prospective observational study was carried out in a tertiary care hospital in New Delhi, India from May 2014 to June 2015 to report adverse drug reactions (ADRs) in patients with type 2 diabetes mellitus (T2DM) using antidiabetic drugs. A total of 220 patients (121 males, 99 females) were enrolled. ADRs were recorded on the prescribed form. Causality and severity assessment was done using Naranjo's probability scale and modified Hartwig and Siegel's severity scale, respectively. Commonly prescribed drugs were biguanides, peptide hormone and sulphonylurea. A total of 26 ADRs were recorded (16 in males and 10 in females). Most commonly observed ADRs were related to endocrine and gastrointestinal system. Severity assessment of ADRs showed seven (26.9%) ADRs as moderate, and 19 (73.1%) as mild. No severe reactions were observed. ADRs were mostly related to endocrine and gastrointestinal system. More information on prescribed drugs and their side effects is required for ensuring patient safety.

Insulin Resistance in Young Obese Subjects and Its Relation to Smoking (A Pilot Study).

Insulin resistance is a condition in which cells fail to respond to the normal actions of insulin. Dietary fat, obesity and smoking have been attributed to increase insulin resistance. However, the prevalence of insulin resistance in young obese subjects and its relation to smoking is not well established. This study comprising seventy-five healthy young adults was undertaken to find insulin resistance in obese smokers and non smokers both. Present study showed an overall prevalence of raised homeostatic model assessment of insulin resistance in 14.7 % otherwise healthy young subjects (20-30 years age group). Non-smokers did not show any significant correlation between insulin resistance and body mass index at either stage (normal, pre-obese as well as obese). Smokers also did not show any significant difference of insulin resistance in normal and pre-obese stages. However, marked increase in homeostatic model assessment of insulin resistance was observed in obese smokers. Homeostatic model assessment of insulin resistance showed a linear trend in relation to body mass index and its values were found to be higher in smokers. Obesity combined with smoking demonstrated statistically significant increase in homeostatic model assessment of insulin resistance.

Quality of Life in Patients with Coronary Artery Disease and Panic Disorder: A Comparative Study.

OBJECTIVES: The quality of life (QOL) of patients with coronary artery disease (CAD) is known to be impaired. Non-cardiac chest pain referrals are often under-diagnosed and untreated, and there are hardly any studies comparing the QOL of CAD and panic disorder related (non-cardiac) chest pain referrals (PDRC). METHODS: We assessed the psychiatric morbidity and QOL of patients newly diagnosed with CAD (n = 40) at baseline and six weeks post-treatment and compared their QOL with patients with PDRC (n = 40) and age- and gender-matched healthy controls (n = 57). Psychiatric morbidity in the CAD group was assessed using the General Health Questionnaire (GHQ12) item, Hamilton Anxiety Scores (HAM-A), and Hamilton Depression Scores (HAMD). QOL measures were determined by the World Health Organization QOL questionnaire (brief) and Seattle Angina Questionnaire. The CAD group was treated with anti-ischemic drugs (nitrates, betablockers), antiplatelet drugs (acetylsalicylsalicylic acid), anticoagulants (low molecular weight heparin, clopidogrel), and managed for risk factors. The PDRC group was treated with selective serotonin reuptake inhibitors and anxiolytics. RESULTS: Patients with panic disorder had a worse QOL than those with CAD and healthy controls in the physical domain and psychological domain (PDRC vs. CAD vs. healthy controls, p < 0.001). In the CAD group, smoking was associated with change in angina stability (p = 0.049) whereas other tobacco products were associated with change in angina frequency (p = 0.044). Psychiatric morbidity was present in 40.0% of patients with CAD. In the PDRC group, a significant correlation of HAM-A scores was noted in the physical (p = 0.000), psychological (p = 0.001), social (p = 0.006), and environment (p = 0.001) domains of QOL. Patients with panic disorder had a significant improvement in anxiety scores after treatment compared to baseline (HAM-A scores difference 21.0 [16.5-25.6]; p < 0.001). CONCLUSIONS: Patients in the PDRC group had a worse QOL than those in the CAD and healthy control groups. This highlights the need for careful diagnosis and prompt treatment of panic disorder in these patients to improve their QOL. Additionally, smoking, the use of other tobacco products, and hypercholesterolemia were associated with angina symptoms in patients with CAD.

The intergenerational transmission of tobacco habit: Role of parents and the family.

INTRODUCTION: Tobacco pandemic has become one of the greatest public health challenges of all time. The socio-environmental factors prevailing at home have been identified as one of the most important causes of adopting smoking and other types of smokeless tobacco. OBJECTIVES: The present study was conducted to find out the prevalence and pattern of tobacco use in the patients registered in the clinic and to study the role of parental and family influence on tobacco use. MATERIALS AND METHODOLOGY: This cross-sectional study was performed in a Tertiary Care Hospital in Delhi. The study included all 307 patients who were registered in a cardiac clinic between January and December 2014. The history of tobacco use in siblings, offspring, and parents was taken from these patients. Pedigree profiles provided detailed information about tobacco use in the family. The association between the use of tobacco among parents and tobacco habits was assessed by odds ratio and Chi-square test. RESULTS: Among the patients, 48% were tobacco users and family history of tobacco use was present in 81% of users. Odds ratio of tobacco use in parents, offspring, siblings, and three generations was 3.477, 1.987, 2.626, and 7.626 than that of nontobacco users. CONCLUSION: Previous anti-smoking campaigns have concentrated much of their effort on discouraging individuals from smoking with the aim of creating a nonsmoking generation. This approach does not take sufficient account of the fact, reconfirmed by our findings that children are influenced by the behavior and attitudes of adults, especially their parents.

Prevalence and correlates of nicotine dependence among construction site workers: A cross-sectional study in Delhi.

INTRODUCTION: Workers represent half the world's population and are major contributors to economic and social development. Tobacco consumption in construction site workers has been considered a big challenge. OBJECTIVES: (1) To assess the prevalence of nicotine dependence among tobacco users. (2) To study the correlates of nicotine dependence among the construction site workers. METHODOLOGY: A cross sectional study was conducted using a predesigned and pretested structured proforma. The study was conducted among all construction site workers aged 18yrs and above in campus of Hamdard Institute of Medical Sciences and Research and associated HAH centenary hospital, New Delhi. Karl Fagerstrom Nicotine Dependence Questionnaire was used to assess dependence on nicotine. RESULTS: The mean age of construction site workers was 32.04±11.6 years. Among the workers, majority (91%) were tobacco user. Among the users, 60% found it difficult to refrain from smoking/chewing in places where use of tobacco is not allowed (e.g. hospitals, government offices, cinemas, Libraries etc). 55% of the users smoked or chewed tobacco during the first hours after waking than during the rest of the day. On multivariate analysis, the factors which were found to be significantly associated with nicotine dependence were lower income group (OR 2.57, CI:1.66-3.99), smokeless tobacco use (OR 2.36, CI:1.30-4.27) and lower education (OR = 2.86 (95% CI 1.97-4.16) for illiterate). DISCUSSION: The prevalence of tobacco use (91%) among construction workers is very high compared to that in the general population. Recognition of construction sites as work places and proper implementation of law is needed.
