Regional variations in cardiovascular risk factors in India: India heart watch

Assessment of prescription pattern and impact of statin in lipid profile among ischemic heart disease patients

BACKGROUND

Analysis of prescription patterns and lipid profiles can play a crucial role in rational drug use and patient safety. This study aimed to analyze the prescription pattern and impact of statin in lipid profile among ischemic heart disease (IHD) patients.

MATERIALS AND METHODS

A prospective observational study was conducted for 7 months in the cardiology department. IHD patients above 18 years and undergoing statin therapy for at least 3 months were enrolled. Patients with elevated liver enzymes and unfit for statin therapy, pregnant women, psychiatry patients, and critically ill subjects were excluded.

RESULTS

Of the total participants, 214 (71.8%) were males and 84 (28.2%) were females, with a mean age of 62.55 ± 9.56 years. The most common age group diagnosed with IHD was between 60 and 69 years. Hypertension was observed in 64.4% of the patients, while diabetes was present in 55.7% as the most commonly associated comorbidities. The majority of patients (75.8%) received atorvastatin. The prescription pattern for various drug classes included proton pump inhibitors (93%), antiplatelet agents (82.2%), statins (82.2%), nitrates (60.4%), beta-blockers (34.6%), diuretics (16.8%), biguanides (17.4%), and insulin (15.1%). After 3 months of statin therapy, a statistically significant change was observed in the lipid profile (P < 0.001).

CONCLUSION

Statin agents were the most frequently prescribed class of drugs, followed by antiplatelets. Significant improvements were observed in the lipid profile after a 3-month course of statin therapy. Effective therapeutic monitoring can significantly impact a positive health outcome in patients.

Ten-year risk assessment for cardiovascular disease & associated factors among adult Indians (aged 40-69 yr): Insights from the National Noncommunicable Disease Monitoring Survey (NNMS)

Background & objectives Cardiovascular diseases (CVDs) are extremely prevalent in India, making early detection of people at high risk for CVDs and prevention crucial. This study aimed to estimate CVD risk distribution in older adults (40-69 yr) in India using WHO's non-laboratory risk chart and identify factors associated with elevated CVD risk (10%). Methods The current study used a nationally representative sample of 40-69 yr adults in India. The population's 10-yr CVD risk was defined as very low-to-low (10%), moderate (10-20%) and high to very high (>20%). We attempted univariable and multivariable logistic regressions to identify factors related to higher CVD risk (≥10%). Results Out of 4480 participants, 50 per cent were younger participants (40-49 years). The proportions of the population with very low to low, moderate and high to very high CVD risk were 84.9, 14.4 and 0.7 per cent, respectively. The estimated 10-year CVD risk was higher for people with unemployed [Adjusted Odds Ratio (AOR): 5.12; 95% Confidence Interval (CI): 3.63, 7.24], followed by raised blood glucose (AOR: 1.81; 95%CI: 1.39, 2.34). Interpretation & conclusions The non-laboratory-based chart proves valuable in low-resource settings, especially at the primary healthcare level, facilitating efficient CVD risk assessment and resource allocation. Further research is needed to explore the association of second-hand smoke with CVD risk in the Indian population.

Prescription-based cost analysis of medicines for cardiovascular risk factors at Indian Council of Medical Research-Rational Use of Medicine Centre Hospitals of India

OBJECTIVES

India has taken several initiatives to provide health care to its population while keeping the related expenditure minimum. Since cardiovascular diseases are the most prevalent chronic conditions, in the present study, we aimed to analyze the difference in prices of medicines prescribed for three cardiovascular risk factors, based on (a) listed and not listed in the National List of Essential Medicines (NLEM) and (b) generic and branded drugs.

MATERIALS AND METHODS

Outpatient prescriptions for diabetes mellitus, hypertension, and dyslipidemia were retrospectively analyzed from 12 tertiary centers. The prices of medicines prescribed were compared based on presence or absence in NLEM India-2015 and prescribing by generic versus brand name. The price was standardized and presented as average price per medicine per year for a given medicine. The results are presented in Indian rupee (INR) and as median (range).

RESULTS

Of the 4,736 prescriptions collected, 843 contained oral antidiabetic, antihypertensive, and/or hypolipidemic medicines. The price per medicine per year for NLEM oral antidiabetics was INR 2849 (2593-3104) and for non-NLEM was INR 5343 (2964-14364). It was INR 806 (243-2132) for generic and INR 3809 (1968-14364) for branded antidiabetics. Antihypertensives and hypolipidemics followed the trend. The price of branded non-NLEM medicines was 5-22 times higher compared to generic NLEM which, for a population of 1.37 billion, would translate to a potential saving of 346.8 billion INR for statins. The variability was significant for sulfonylureas, angiotensin receptor blockers, beta-blockers, diuretics, and statins (P < 0.0001).

CONCLUSION

The study highlights an urgent need for intervention to actualize the maximum benefit of government policies and minimize the out-of-pocket expenditure on medicines.

Development and validation of multicentre study on novel Artificial Intelligence-based Cardiovascular Risk Score (AICVD)

OBJECTIVE

Cardiovascular diseases (CVD) are one of the most prevalent diseases in India amounting for nearly 30% of total deaths. A dearth of research on CVD risk scores in Indian population, limited performance of conventional risk scores and inability to reproduce the initial accuracies in randomised clinical trials has led to this study on large-scale patient data. The objective is to develop an Artificial Intelligence-based Risk Score (AICVD) to predict CVD event (eg, acute myocardial infarction/acute coronary syndrome) in the next 10 years and compare the model with the Framingham Heart Risk Score (FHRS) and QRisk3.

METHODS

Our study included 31 599 participants aged 18-91 years from 2009 to 2018 in six Apollo Hospitals in India. A multistep risk factors selection process using Spearman correlation coefficient and propensity score matching yielded 21 risk factors. A deep learning hazards model was built on risk factors to predict event occurrence (classification) and time to event (hazards model) using multilayered neural network. Further, the model was validated with independent retrospective cohorts of participants from India and the Netherlands and compared with FHRS and QRisk3.

RESULTS

The deep learning hazards model had a good performance (area under the curve (AUC) 0.853). Validation and comparative results showed AUCs between 0.84 and 0.92 with better positive likelihood ratio (AICVD -6.16 to FHRS -2.24 and QRisk3 -1.16) and accuracy (AICVD -80.15% to FHRS 59.71% and QRisk3 51.57%). In the Netherlands cohort, AICVD also outperformed the Framingham Heart Risk Model (AUC -0.737 vs 0.707).

CONCLUSIONS

This study concludes that the novel AI-based CVD Risk Score has a higher predictive performance for cardiac events than conventional risk scores in Indian population.

Financial burden of coronary artery bypass grafting in India: implications for catastrophic health expenditure and healthcare access

Cardiovascular diseases (CVD) have become a leading cause of mortality in India. High costs of coronary artery bypass grafting (CABG) impose a financial burden in patients often resulting in catastrophic health expenditure (CHE). CHE and distressed financing have significant microeconomic and macroeconomic implications. CHE depletes savings, forces asset disposal, and perpetuates poverty. At a macroeconomic level, the burden of CVD impacts gross domestic product, economic productivity, healthcare budgets, and social welfare. Addressing these challenges requires a multifaceted approach. Prioritizing accessible and affordable healthcare systems with robust financial risk protection is essential. Widespread adoption of health insurance, including government-sponsored schemes, can provide financial protection. Expanding public healthcare infrastructure, implementing price regulations, promoting generic medicines, and encouraging preventive measures for coronary artery disease (CAD) are crucial steps to reduce the burden of CABG costs and improve healthcare access.

The 'Insertion/Deletion' Polymorphism, rs4340 and Diabetes Risk: A Pilot Study from a Hospital Cohort

The insertion/deletion, I/D polymorphism, in the gene encoding Angiotensin Converting Enzyme, ACE is a popular genetic marker for cardiovascular disease, CVD. With alarming rise in diabetes, the risk of CVD among Indian subjects is further enhanced. The present study explored the role of ACE I/D polymorphism, rs4340 as a genetic marker and its association with diabetes. Genomic DNA, isolated from a cohort of 410 urban subjects attending our hospital, was genotyped using polymerase chain reaction followed by electrophoresis. Among the subjects, 84 had type-2 diabetes and 68 had hypertension while 258 were free from these risk factors. Majority (57/84) of diabetic subjects were also suffering from hypertension. Genotype frequencies of ACE I/D polymorphism, of diabetic (84) patients were not different from that of non-diabetic subjects (258). In sharp contrast, we found significant differences, in genotype frequencies of women with diabetes (n = 38) compared to non-diabetic women (70). Diabetic women had significantly higher prevalence of the high risk 'D' allele. Analysis of odds ratio, OR revealed that women with 'D/D' genotype, exhibited threefold risk (OR 3.12, 95% CI 1.21-8.05; p = 0.018) of diabetes, in the recessive model (D/D vs I/I + I/D). Further when we analysed Odds ratio of diabetic women (8) who were free from hypertension, the results revealed even a greater, 6- fold (OR 6.0, 95% CI 1.29-27.96, p = 0.027) risk of diabetes for D/D homozygous women (D/D vs I/I + I/D). These results suggest 'sex-specific' association of ACE 'I/D' polymorphism, with type-2 diabetes, affecting women while there was no influence observed among men. In view of the increased cardiovascular mortality among Indians, data from our pilot study if confirmed in a larger cohort, could add value to our future intervention efforts.

Association between serum osteocalcin and atherosclerosis in Type-2 diabetes mellitus: a cross-sectional study

BACKGROUND

The past few decades have seen a marked increase in the macrovascular complications of Type-2 diabetes mellitus (T2DM) such as coronary heart disease, peripheral arterial disease, and cerebrovascular disease. This has been predominantly attributed to the increased atherosclerosis in these patients. Atherosclerosis usually remains an asymptomatic condition and this poses a significant challenge in its early diagnosis and timely intervention. Hence, there is an immediate need for exploring novel tools to aid in the early detection of atherosclerosis, especially in T2DM patients. Osteocalcin (OC), synthesized by osteoblasts, is a protein hormone found in the skeletal system. This protein is considered as a marker for bone density and in recent times has been gaining interest due to its protective role in cerebrovascular diseases(CVD).

METHODS

We conducted a cross-sectional study and evaluated the association between serum OC levels and atherosclerosis in 113 T2DM patients. Carotid intima-media thickness (CC-IMT) was used as an estimate of atherosclerosis and patients were divided into two groups (CC-IMT < 0.9 and ≥ 0.9). Correlation of serum OC levels and glycemic parameters and lipid profiles were studied and compared between both groups.

RESULTS

There is a significant negative correlation between the CC-IMT estimates and serum OC levels. CC-IMT also has a significant association with other biochemical parameters such as fasting blood sugar, glycated hemoglobin and high-density lipoprotein.

CONCLUSION

Although the independent association of serum OC could not be established in the T2DM patient population, overall, the results favor low serum OC as a prognostic marker for atherosclerosis.

The Health Implications of Perceived Anti-Muslim Discrimination Among South Asian Muslim Americans

Introduction

Anti-Muslim discrimination in the U.S. has increased exponentially since 2001, but the impact of anti-Muslim discrimination has yet to be fully examined because of limited data available on this topic and population. The objectives of this study were to (1) examine the association between perceived anti-Muslim discrimination and health risk behaviors, with depressive symptoms as a potential mediator, among South Asian Muslim Americans and (2) examine the association between other forms of perceived discrimination and health risk behaviors, with depressive symptoms as a potential mediator, among South Asian Muslim Americans.

Methods

Data were collected using an online survey, which was disseminated on subscriber e-mail lists for organizations that serve South Asian or Muslim communities. Participants were asked about perceived discrimination, depressive symptoms, diet, physical activity, tobacco use, and alcohol consumption. Data were analyzed using structural equation modeling in Mplus 8.

Results

Societal anti-Muslim discrimination had a positive association with depressive symptoms (0.19, p<0.05), as did interpersonal anti-Muslim discrimination (0.20, p<0.05) and other forms of discrimination (0.22, p<0.05). None of the discrimination scales were associated with dietary patterns, tobacco use, or alcohol consumption.

Conclusions

Study results demonstrated a link between discrimination and depressive symptoms. Further research is needed to examine associations with other adverse health outcomes and potential buffers against discrimination.

Peptidomimetics for CVD screened via TRADD-TRAF2 complex interface assessments

The main aim of this study is to screen and develop Peptidomimetics to treat atherosclerosis (AS) which is a Cardio Vascular Disease (CVD). Peptidomimetics were obtained from the protein-protein interaction interface of TRADD (Tumor necrosis factor receptor type 1-associated DEATH domain protein) and TRAF2 (TNF receptor-associated factor 2) complex. TRADD-TRAF2 interaction is critical in AS pathogenesis since it assists a series of signal transducers that activate NF-κB. Conceptually, the triggered NF-κB makes an extensive amount of nitric oxide (NO) synthesized by inducible nitric oxide synthase (iNOS), which boons the progress of AS. The examined TRADD-TRAF2 complex (PDB ID: 1F3V) and its interaction details revealed that the sequence range W11-G165 of TRADD highly interacts with TRAF2. The sequence range W11-G165 was selected for the design and preparation of the inhibitory peptide in silico. The selected sequence was mutated with the alanine scanning method to have a range of inhibitory peptides. With the help of different in silico tools, the top three, namely MIP11-25 L, MIP131-143 h, and MIP149-164 m peptides showed the best interaction with the critical residues of TRAF2. Thus, these three peptides were used for generating peptidomimetics using pepMMsMIMIC, a peptidomimetics virtual screening tool. Around 600 peptidomimetics were identified & and retrieved for further screening by employing molecular docking tools and MD (Molecular Dynamics) simulations. Density Functional Theory (DFT) and ADMET predictions were applied to validate the screened peptidomimetics druggability. In the results, peptidomimic compounds MMs03918858 and MMs03927281 with binding energy values of -9.6 kcal/mol and - 9.1 kcal/mol respectively were screened as the best and are proposed for further pre-clinical studies.

Socio-economic distribution of modifiable risk factors for cardiovascular diseases: An analysis of the national longitudinal ageing study in India

The association of socioeconomic status (SES) with modifiable risk factors for cardiovascular diseases (CVDs) is unclear in developing nations. We studied SES variations in major risk factors and their percentage distribution for adults aged 45 years or above in India. Using individual records of 59,672 individuals aged 45 years or above from the Longitudinal Ageing Study in India Wave 1 (cross-sectional study design), 2017-18, we chart age-and-sex-adjusted prevalence of clinical risk factors such as measured high blood pressure, hypertension, overweight, obesity, central adiposity and self-reported high blood glucose; and lifestyle risk factors such as excessive use of alcohol, current use of smoking and smokeless tobacco and physical inactivity across SES variables of education, quintiles of mean per capita expenditure and social caste. Multivariable analysis was used to explore the SES gradient of risk factors. The sample used in the study is predominantly rural (69.9%), illiterate (50.7%), has more females (54.2%), and belongs to other backward classes (45.6%). Prevalence of high blood pressure, overweight, obesity, central adiposity, high blood glucose, and physical inactivity increased; and excessive alcohol consumption and current use of smoking/smokeless tobacco decreased with income, education, and social caste. However, no significant income gradient was noted for lifestyle risk factors except the use of smokeless tobacco. The income gradient was largest for central adiposity (waist-circumference) with a difference of 23.4 percentage points as it increased from 38.7% among the poorest to 62.1% among the richest. The major burden of CVDs risk factors among older adults aged 45+ years falls among high SES.

Prevalence and risk factor of diabetes among the elderly people in West Bengal: evidence-based LASI 1st wave

BACKGROUND

The complication of Diabetes is one of the important health issues among the older adult population in any region. The higher risks of diabetes prevalence among older adult people in the countries was due to social-cultural changes such as increasing urbanization, dietary changes, without physical activity, and unhealthy lifestyle behavior. The present study examines the prevalence and associated risk factors of diabetes among older adults in the state of West Bengal.

METHODS

The first wave of the Longitudinal Ageing Study in India 2017-18 was used to achieve the study objectives. Descriptive statistics with multinomial logistic regression models were used to carry out crude and adjusted odds ratios with 95% confidence intervals and examine the associated risk factors of diabetes prevalence among older adults.

RESULTS

The findings of the study indicate that the overall prevalence of diabetes among the study participants was found to be 12.4% which was significantly higher in urban areas (19%) compare to rural areas (6%). The socio-economic and bio-demographic factors like educational status, richest background family, marital status, obesity, and family history of diabetes were significantly associated with higher risks of diabetes prevalence among the older adult population in West Bengal. The risks of diabetes in the richest adult people were significantly higher than in the poorest adult people (OR = 2.78; 95% CI: 1.974-3.917). The higher risks of diabetes mellitus among the richest wealthy people are because of lifestyle behavior, smoking, and tobacco consumption respectively.

CONCLUSION

The study needs to policy and awareness program to reduce economic inequality and prevention of diabetes care and treatment-seeking behavior, especially for the older adult population in West Bengal.

Gender differences in premature mortality for cardiovascular disease in India, 2017-18

BACKGROUND

The present study tries to provide a comprehensive estimate of gender differences in the years of life lost due to CVD across the major states of India during 2017-18.

METHODS

The information on the CVD related data were collected from medical certification of causes of death (MCCD reports, 2018). Apart from this, information from census of India (2001, 2011), SRS (2018) were also used to estimate YLL. To understand the variation in YLL due to CVD at the state level, nine sets of covariates were chosen: share of elderly population, percentage of urban population, literacy rate, health expenditure, social sector expenditure, labour force participation, HDI Score and co-existence of other NCDs such as diabetes, & obesity. The absolute number of YLL and YLL rates were calculated. Further, Pearson's correlation had been calculated and to understand the effect of explanatory variables on YLL due to CVD, multiple linear regression analysis had been applied.

RESULTS

Men have a higher burden of premature mortality in terms of Years of life lost (YLL) due to CVD than women in India, with pronounced differences at adult ages of 50-54 years and over. The age pattern of YLL rate suggests that the age group 85 + makes the highest contribution to the overall YLL rate due to CVD. YLL rate showed a J-shaped relationship with age, starting high at ages below 1 years, dropping to their lowest among children aged 1-4 years, and rising again to highest levels at 85 + years among both men and women. In all the states except Bihar men had higher estimated YLL due to CVD for all ages than women. Among men the YLL due to CVD was higher in Tamil Nadu followed by Madhya Pradesh and Chhattisgarh. On the other hand, the YLL due to CVD among men was lowest in Jharkhand followed by Assam. Similarly, among women the YLL due to CVD was highest in Tamil Nadu followed by Madhya Pradesh and Chhattisgarh. While, the YLL due to CVD among women was lowest in Jharkhand. Irrespective of gender, all factors except state health expenditure were positively linked with YLL due to CVD, i.e., as state health expenditure increases, the years of life lost (YLL) due to CVDs falls. Among all the covariates, the proportion of a state's elderly population emerges as the most significant predictor variable for YLL for CVDs (r = 0.42 for men and r = 0.50 for women).

CONCLUSION

YLL due to cardiovascular disease varies among men and women across the states of India. The state-specific findings of gender differences in years of life lost due to CVD may be used to improve policies and programmes in India.

The burden of disease-specific multimorbidity among older adults in India and its states: evidence from LASI

BACKGROUND

Around the world, advances in public health and changes in clinical interventions have resulted in increased life expectancy. Multimorbidity is becoming more of an issue, particularly in countries where the population is rapidly ageing. We aimed to determine the prevalence of multimorbidity and disease-specific multimorbidity and examine its association with demographic and socioeconomic characteristics among older adults in India and its states.

METHODS

The individual data from the longitudinal ageing study in India (LASI) were used for this study, with 11 common chronic conditions among older adults aged 60 and above years (N = 31,464). Descriptive statistics were used to report the overall prevalence of multimorbidity and disease-specific burden of multimorbidity. Multinomial logistic regression has been used to explore the factors associated with multimorbidity.

RESULTS

Prevalence of single morbidity was 30.3%, and multimorbidity was 32.1% among older people in India. Multimorbidity was higher among females and in urban areas and increased with age and among those living alone. Hypertension, arthritis and thyroid were highly prevalent among females and chronic lung diseases and stroke were highly prevalent among males. The older people in the state of Kerala had a high prevalence of multimorbidity (59.2%). Multimorbidity was found to be more likely in older age groups of 75-79 years (RR-1.69; CI: 1.53-1.87) and 80 years and above (RR-1.40; CI: 1.27-1.56) and in the Western (RR-2.16; CI: 1.90-2.44) and Southern regions (RR-2.89; CI: 2.57-3.24). Those who were living with a spouse (RR-1.60; CI: 1.15-2.23) were more likely to have multimorbidity. Disease-specific multimorbidity was high in chronic heart disease (91%) and low in angina (64.8%).

CONCLUSIONS

The findings suggest that multimorbidity has a positive relationship with advancing age, and disease-specific burden of multimorbidity is higher among chronic heart patients. Comorbidity, especially among those who already have chronic heart disease, stroke, cholesterol or thyroid disorder can have severe consequences on physical functioning, therefore, disease-specific health management needs to be enhanced.

Cardiovascular diseases and ageing in India: A propensity score matching analysis of the effects of various risk factors

Cardiovascular diseases (CVDs) are one of the major causes of mortality and morbidity worldwide, with a significant burden, especially on older adults. This analysis aims to estimate the exclusive effects of various risk factors of CVDs among 59,073 older adults aged 45 years and above in India. Using data from wave 1 of the Longitudinal Ageing Study in India (LASI), the exposure effects of various risk factors on CVDs are estimated through propensity score matching. This analysis is further extended to different components of CVDs, such as hypertension, heart disease, and stroke. Results indicate that risk factors groups such as environmental, behavioral, physiological, and genetic risk factors have a positive and significant impact on CVDs. In the case of independent risk factor effects, diabetes has the highest effect on CVDs, followed by overweight, cholesterol, family history, alcohol consumption, and depression. We conclude that physiological risk factors among older adults are more severe than other factors.

The prevalence of risk factors and pattern of obstructive coronary artery disease in young Indians (< 45 years) undergoing percutaneous coronary intervention: A gender-based multi-center study

Objectives

In a retrospective study, we aimed to explore the prevalence of risk factors and trends of obstructive coronary artery disease (CAD) in Indian females <45 years of age compared to males of the same age group who underwent percutaneous coronary intervention (PCI).

Materials and Methods

This was a retrospective, observational, multi-centre study of young Indian females and males (<45 years) who underwent PCI as per the guidelines at three high-volume centres in India.

Results

In a group of 3656 patients under the age of 45 who had PCI, 3.1% of those with obstructive CAD were young women (n = 113), while 6.9% were young men (n = 254). Traditional risk factors such as hypertension (p = 0.73), diabetes (p = 0.61), and family history of premature CAD (p = 0.63) were equally common in both genders, whereas dyslipidaemia (p < 0.001), overweight (p < 0.006), smoking (p = 0.004) and, alcoholism (p < 0.001) were more common in young males. Acute coronary syndrome was the most common clinical presentation. Single-vessel disease was common, with the involvement of the left anterior descending artery as the most common angiographic feature. The prevalence of cardiogenic shock was 4.4% in females and 4.1% in males, while the in-hospital mortality rate was 1.77% in young females and 2% in young males.

Conclusions

Obstructive CAD in young men and women accounted for 10% of all CAD cases requiring PCI. Although men account for the majority of patients, CAD in women under the age of 45 is not uncommon. Traditional risk factors are becoming more prevalent in younger women.

High Prevalence of Additional Cardiovascular Risk Factors in Eastern-Indian Young Adults with Type 2 Diabetes Mellitus

BACKGROUND AND AIMS

The American Diabetes Association recommends statin therapy for young type 2 diabetes mellitus (T2DM) adults only if one additional cardiovascular (CV) risk factor coexists. The data regarding CV risk factors in young Indian T2DM adults is limited. Hence, we assessed the prevalence of CV risk factors in young adults with T2DM from eastern India.

METHODS

In this cross-sectional study, diabetic medical health check records of eastern-Indian T2DM patients performed between March 2018 and March 2019 were retrospectively reviewed and the relevant data of T2DM patients (n = 3564) including CV risk factors [serum LDL-cholesterol of ≥100 mg/dL, hypertension (>140/90 mmHg), smoking, chronic kidney disease (eGFR of <60 ml/min), microalbumin to creatinine ratio of ≥30 mg/mg, and obesity/overweight (body mass index ≥23 kg/m²)] were analysed.

RESULTS

There were 3280 T2DM patients from eastern India and 679 (20.7%) were ≤40 years of age. Overweight/obesity (74.3%) and serum LDL-cholesterol of ≥100 mg/dL (69.2%) were the two most common additional CV risk factors. At least one additional CV risk factor was present in 576 (95.36%) patients, whereas at least two additional CV risk factors were present in 409 (67.7%) patients. At least one non-obesity/overweight CV risk factor was present in 472 (78.1%) patients.

CONCLUSIONS

The study demonstrates a high prevalence of additional CV risk factors in young eastern-Indian adults with T2DM. Hence, there is a need for an intensive approach to managing the CV risk factors in young Indian adults with T2DM.

The effects of dual antiplatelet therapy (DAPT) adherence on survival in patients undergoing revascularization and the determinants of DAPT adherence

BACKGROUND

The prevalence and burden of coronary heart disease (CHD) has increased substantially in India, accompanied with increasing need for percutaneous coronary interventions (PCI). Although a large government-funded insurance scheme in Maharashtra, India covered the cost of PCI for low-income patients, the high cost of post-PCI treatment, especially Dual Antiplatelet Therapy (DAPT), still caused many patients to prematurely discontinue the secondary prevention. Our study aimed to investigate the effectiveness of DAPT adherence on all-cause mortality among post-PCI patients and explore the potential determinants of DAPT adherence in India.

METHOD

We collected clinical data of 4,595 patients undergoing PCI in 110 participating medical centers in Maharashtra, India from 2012 to 2015 by electronic medical records. We surveyed 2527 adult patients who were under the insurance scheme by telephone interview, usually between 6 to 12 months after their revascularization. Patients reporting DAPT continuation in the telephone survey were categorized as DAPT adherence. The outcome of the interest was all-cause mortality within 1 year after the index procedure. Multivariate Cox proportional hazard (PH) model with adjustment of potential confounders and standardization were used to explore the effects of DAPT adherence on all-cause mortality. We further used a multivariate logistic model to investigate the potential determinants of DAPT adherence.

RESULTS

Out of the 2527 patients interviewed, 2064 patients were included in the analysis, of whom 470 (22.8%) discontinued DAPT prematurely within a year. After adjustment for baseline confounders, DAPT adherence was associated with lower one-year all-cause mortality compared to premature discontinuation (less than 6-month), with an adjusted hazard ratio (HR) of 0.52 (95% Confidence Interval (CI) = (0.36, 0.67)). We also found younger patients (OR per year was 0.99 (0.97, 1.00)) and male (vs. female, OR of 1.30 (0.99, 1.70)) had higher adherence to DAPT at one year as did patients taking antihypertensive medications (vs. non medication, OR of 1.57 (1.25, 1.95)).

CONCLUSION

These findings suggest the protective effects of DAPT adherence on 1-year mortality among post-PCI patients in a low-income setting and indicate younger age, male sex and use of other preventive treatments were predictors of higher DAPT adherence.

Psychological Symptoms as Mediators in the Association between Discrimination and Health among South Asian Americans

Objective

To examine psychological symptoms (symptoms of depression, anger, anxiety) as potential mediators between discrimination and health outcomes among South Asian Americans. We hypothesized that psychological symptoms would be significant mediators in the pathways between discrimination and health.

Research Design and Methods

The Mediators of Atherosclerosis in South Asians Living in America (MASALA) Study examines risk factors for heart disease among South Asian Americans using self-reported and medical data collected from participants in the San Francisco Bay Area and Chicago regions of the U.S. (N=1164). For this study we assessed the associations among the everyday discrimination scale, symptoms of depression, anxiety, and anger, and health outcomes using structural equation modeling.

Results

We found significant positive associations between discrimination and symptoms of depression (ß .69, p<.0001), anger (ß .38, p<.0001), and anxiety (ß .64, p<.0001). Exposure to discrimination had a direct negative association with HDL level (ß -.37, p=.01). Indirect associations between discrimination and health outcomes were seen via depression (tobacco use: ß 1.08, p=.007), via anger (triglyceride level: 11.88, p=.03; alcohol consumption: ß 1.66, p=.002; calories consumed per day: ß 108.04, p=.02), and via anxiety (tobacco use: ß -1.05, p=.004; alcohol consumption: ß -1.88, p=.03).

Conclusion

Our hypothesis was partially confirmed with proximate health indicators (tobacco use, alcohol consumption, caloric intake) and triglyceride levels. These results suggest that psychological symptoms mediate the association between discrimination and adverse health risk behaviors among South Asian Americans.

About 50% rated a happiness quotient of 7 and 8. Surgeons had more diabetes and hypertension than physicians. Prevalence of hypertension was more in self-employed males versus males in job. About two-third participants scored ≥ 80% on healthy lifestyle score.

Conclusion

Our results call for a well-thought strategy to overcome the financial and technological hindrances to accurately identify health risk factors and plan corrective interventions. A healthy lifestyle both in terms of diet and exercise should be incorporated into the schedules of doctors.

Circulating Levels of IL-13, TGF-β1, and Periostin as Potential Biomarker for Coronary Artery Disease with Acute Heart Failure

Objective

Coronary artery disease (CAD) and associated comorbidities such as heart failure (HF) remain the leading cause of morbidity and mortality worldwide, attributed to, at least partially, the lack of biomarkers for efficient disease diagnosis. The study intended to explore potential biomarkers for predicting the presence of HF in CAD patients.

Methods

According to the presence of HF, 83 CAD patients with HF were assigned to the AHF group and 52 CAD patients without HF to the CAD group. Additionally, healthy controls (n = 52) were those who had received physical examinations at the same period. The serum levels of IL-13, TGF-β1, and periostin were detected by the enzyme-linked immunosorbent assay (ELISA). Left ventricular ejection fraction (LVEF), left ventricular end-diastolic dimension (LVEDD), left ventricle-end diastolic volume (LVEDV), and left ventricular mass index (LVMI) were detected 3 times by color Doppler ultrasound. The predictive values of IL-13, TGF-β1, and periostin methods were compared by receiver-operating characteristic (ROC) analysis and the area under the curve (AUC).

Results

Increased levels of IL-13, TGF-β1, and periostin were noted in the AHF group than in the control and CAD groups (p < 0.001); the CAD group showed higher levels of IL-13, TGF-β1, and periostin than the control group (p < 0.001). Based on the NYHA classification, there were 33 cases with grade II, 28 cases with grade III, and 22 cases with grade IV among 83 CAD patients with HF. It was found that the serum levels of IL-13, TGF-β1, and periostin were higher in the AHF-IV group than in the AHF-III and AHF-II groups (p < 0.001); these levels were also higher in the AHF-III group than in the AHF-II group (p < 0.001). The periostin level was positively correlated with the levels of IL-13 (r = 0.458) and TGF-β1 (r = 0.569) in CAD patients with AHF. Besides, the serum levels of periostin (r = -0.425), IL-13 (r = -0.341), and TGF-β1 (r = -0.435) were negatively correlated with the LVEF of CAD patients with AHF, respectively. When IL-13, TGF-β1, and periostin levels were used to predict the presence of AHF in CAD patients in combination, the sensitivity and specificity were 75.9% and 90.38%, respectively, with the AUC of 0.906 (95% CI: 0.912–0.996).

Conclusion

These data reveal that IL-13, TGF-β1, and periostin levels might be associated with the occurrence of AHF in CAD patients and their combination shows the predictive value for the presence of AHF in CAD patients.

A Sustainable Community-Based Model of Noncommunicable Disease Risk Factor Surveillance (Shraddha-Jagrithi Project): Protocol for a Cohort Study

BACKGROUND

India has a massive noncommunicable disease (NCD) burden, at an enormous cost to the individual, family, society, and health system at large, despite which prevention and surveillance are relatively neglected. If diagnosed early and treated adequately, risk factors for atherosclerotic cardiovascular disease would help decrease the mortality and morbidity burden. Surveillance for NCDs, creating awareness, positive lifestyle changes, and treatment are the proven measures known to prevent the progression of the disease. India is in a stage of rapid epidemiological transition, with the state of Kerala being at the forefront, pointing us towards likely disease burden and outcomes for the rest of the country in the future. A previous study done by the same investigators in a population of >100,000 revealed poor awareness, treatment of NCDs, and poor adherence to medicines in individuals with CVD.

OBJECTIVE

This study aimed at assessing a sustainable, community-based surveillance model for NCDs with corporate support fully embedded in the public health system.

METHODS

Frontline health workers will check all individuals in the target group (≥age 30 years) with further follow-up and treatment planned in a "spoke and hub" model using the public health system of primary health centers as spokes to the hubs of taluk or district hospitals. All data entry done by frontline health workers will be on a tablet PC, ensuring rapid acquisition and transfer of participant health details to primary health centers for further follow-up and treatment.

RESULTS

The model will be evaluated based on the utilization rate of various services offered at all tier levels. The proportions of the target population screened, eligible individuals who reached the spoke or hub centers for risk stratification and care, and community-level control for hypertension and diabetes in annual surveys will be used as indicator variables. The model ensures diagnosis and follow-up treatment at no cost to the individual entirely through the tiered public health system of the state and country.

CONCLUSIONS

Surveillance for NCDs is an essential facet of health care presently lacking in India. Atherosclerotic cardiovascular disease has a long gestation period in progression to the symptomatic phase of the disease, during which timely preventive and lifestyle measures would help prevent disease progression if implemented. Unfortunately, several asymptomatic individuals have never tested their plasma glucose, serum lipid levels, or blood pressure and are unaware of their disease status. Our model, implemented through the public health system using frontline health workers, would ensure individuals aged≥30 years at risk of disease are identified, and necessary lifestyle modifications and treatments are given. In addition, the surveillance at the community level would help create a general awareness of NCDs and lead to healthier lifestyle habits.

Association of eNOS (G894T, rs1799983) and KCNJ11 (E23K, rs5219) gene polymorphism with coronary artery disease in North Indian population

Background

Endothelial nitric oxide synthase (eNOS) and potassium voltage-gated channel subfamily J member 11 (KCNJ11) could be the candidate genes for coronary artery disease (CAD). This study investigated the relationship of the eNOS (rs1799983) and KCNJ11 (rs5219) polymorphisms with the presence and severity of CAD in the North Indian population.

Methods

This study included 300 subjects, 150 CAD cases and 150 healthy controls. Single nucleotide polymorphism was evaluated by Polymerase chain reaction and Restriction fragment length polymorphism (PCR-RFLP). Analysis was performed by SPSS (version 21.0).

Results

We observed that KK genotype of KCNJ11E23K (rs5219) polymorphism (P=0.0001) genotypes and K allele (P=0.0001) was found to be a positive risk factor and strongly associated with CAD. In the case of eNOSG894T (rs1799983) there was no association found with CAD.

Conclusion

These results illustrate the probability of associations between SNPs and CAD although specific genetic polymorphisms affecting ion channel function and expression have still to be clarified by further investigations involving larger cohorts.

Development and evaluation of air pollution-linked quality of life (AP-QOL) questionnaire: insight from two different cohorts

In this study, the air pollution-related quality of life (AP-QOL) questionnaire was carried out in two geographically and economically different groups including New Delhi (Megacity) and Hamirpur, Himachal Pradesh (town), and APE scores were linked with respiratory and cardiovascular illness. The APE-Score was developed by AP-QOL questionnaire responses using Delphi technique and further analyzed using principal component analysis (PCA). For reliability of APE-Score and AP-QOL questionnaire, α-Cronbach's test and basic statistics were performed. The linear mixed-effect model and odds ratios were used to evaluate air pollution exposure and health outcomes. Overall, 720 academicians and 276 security guards were invited to participate in the questionnaire. Cronbach's α coefficients ranged from 0.70 to 0.84 indicated significant reliability in the AP-QOL questionnaire conducted in this study. Substantial variation in respiratory symptoms and their medical history were found - 76.9% ([95% confidential interval (CI)]: (- 83.8, - 66.9) (p < 0.05)) and - 28.6% (95% CI: (- 37.8, - 18.0) (p < 0.05)), respectively, with interquartile range (IQR) increase of APE score. The odds ratios (ORs) of respiratory medical history (MH Res.) showed a significant increase from 1.01 to 1.35 for low to high air pollution exposure in the academic group of IIT Delhi. Interestingly, for an academic group of NITH, the ORs for medical history of cardiovascular (MH Card.) showed an increase from 1.08 to 1.13 for low to high APE which was not the case for IIT Delhi academicians.

Cardiovascular disease risk and pathophysiology in South Asians: can longitudinal multi-omics shed light?

Cardiovascular disease (CVD) is the leading cause of mortality in South Asia, with rapidly increasing prevalence of hypertension, type 2 diabetes (T2DM) and hyperlipidemia over the last two decades. Atherosclerotic CVD (ASCVD) affects South Asians earlier in life and at lower body weights, which is not fully explained by differential burden of conventional risk factors. Heart failure (HF) is a complex clinical syndrome of heterogeneous structural phenotypes including two major clinical subtypes, HF with preserved (HFpEF) and reduced ejection fraction (HFrEF). The prevalence of HF in South Asians is also rising with other metabolic diseases, and HFpEF develops at younger age and leaner body mass index in South Asians than in Whites. Recent genome-wide association studies, epigenome-wide association studies and metabolomic studies of ASCVD and HF have identified genes, metabolites and pathways associated with CVD traits. However, these findings were mostly driven by samples of European ancestry, which may not accurately represent the CVD risk at the molecular level, and the unique risk profile of CVD in South Asians. Such bias, while formulating hypothesis-driven research studies, risks missing important causal or predictive factors unique to South Asians. Importantly, a longitudinal design of multi-omic markers can capture the life-course risk and natural history related to CVD, and partially disentangle putative causal relationship between risk factors, multi-omic markers and subclinical and clinical ASCVD and HF. In conclusion, combining high-resolution untargeted metabolomics with epigenomics of rigorous, longitudinal design will provide comprehensive unbiased molecular characterization of subclinical and clinical CVD among South Asians. A thorough understanding of CVD-associated metabolomic profiles, together with advances in epigenomics and genomics, will lead to more accurate estimates of CVD progression and stimulate new strategies for improving cardiovascular health.

Periodontal disease among non-diabetic Coronary Heart Disease patients. A case-control study

BACKGROUND

There is well documented scientific evidence supporting the association between Coronary Heart Disease (CHD) and periodontitis. It is however, uncertain if this association is causal or is mediated by the common inflammatory pathways. Hence, the study assessed and compared the Periodontal Health Status among CHD patients with age and gender matched controls.

METHODS

A total of 808 medically confirmed CHD patients were compared with 808 age and gender matched controls. Oral examination was conducted using Simplified Oral Hygiene Index (OHI-S) and modified World Health Organization (WHO) Oral Health Assessment form, 1997. Mean scores were compared using Mann- Whitney-U test and Analysis of Variance (ANOVA). Logistic regression analysed the association between the risk factors and CHD.

RESULTS

Cases had significantly higher mean sextants with pockets and attachment loss ≥4mm compared to controls (p≤0.05). The cases also had significantly poor oral hygiene mean scores compared to controls (p=0.0001*). There was a lower and insignificant association between age (p=0.99), gender (p=0.84) and CHD. Risk factors education (p=0.001), lesser frequency of dental visit (p=0.001) also showed a lower, yet significant association. Risk of CHD was higher among tobacco (Odds ratio (OR) - 2.26) and alcohol (OR-1.83) users. Presence of poor oral hygiene (OR-5.20), pocket of ≥6 mm (6.70) and attachment loss of ≥9 mm (OR-11.31) also showed higher risk of CHD.

CONCLUSION

The study results support the association between periodontal disease and CHD. To halt the epidemic of CHD, emphasis on screening of wide age range, reinforcement of public health systems and early detection is recommended. (www.actabiomedica.it).

Medical nutrition therapy of pediatric type 1 diabetes mellitus in India: Unique aspects and challenges

Medical nutrition therapy (MNT) is a vital aspect of management of type 1 diabetes mellitus (T1DM) and should be tailored to ethnic and family traditions and the socioeconomic and educational status of the patient. In this article, we discuss the unique aspects of MNT in children and adolescents with T1DM in the Indian setting, with focus on the challenges faced by patients, dieticians and physicians and how these can be overcome. The authors reviewed the available literature on MNT in T1DM from India and prepared the document based on their vast collective clinical experience in treating patients with T1DM from different regions in India. Indian diets are predominantly carbohydrate-based with high glycemic index (GI) and low protein content. Various methods are available to increase the protein and fiber content and reduce the GI of food in order to limit glycemic excursions. Insulin regimens need to be tailored to the child's school timings, meal schedule, and the availability of a responsible adult to supervise/administer insulin. All patients, irrespective of economic and education background, should be taught the broad principles of healthy eating, balanced diet and carbohydrate counting. There are various barriers to dietary compliance, including joint family system, changing lifestyles, and other factors which need to be addressed. There is a need to customize dietary management according to patient characteristics and needs and develop standardized patient educational material on principles of healthy eating in various regional languages.

Comparison of original and modified Q risk 2 risk score with Framingham risk score - An Indian perspective

OBJECTIVE

No study among Indian population has proposed modification of existing cardiovascular disease (CVD) risk scores or novel risk scores as risk estimation using conventional risk calculators can't be generalized because of epidemiological differences.

MATERIAL AND METHODS

A single center observational study was performed at a tertiary care center among participants having no evidence of CVD. Prevalence of various cardiac risk factors were analysed and 10-year risk was estimated using Framingham risk score (FRS), Q risk 2 score calculator (QRISK2) and Modified Q risk 2 (mQRISK2) which included smokeless tobacco consumption. QRISK2 and mQRISK2 were compared with FRS and participant's eligibility for statin therapy as primary preventive measure was assessed.

RESULTS

Total of 4045 participants were enrolled from August 2016 to July 2019. 3520(87%) had no history of smoking in their lifetime while smokeless tobacco consumption was seen in 1153(28.5%), diabetes in 422(10.4%), hypertension in 1096(27.1%), obesity in 2035(50.3%), and family history of CVD in 353(8.7%) participants. High risk participants were found to be 826(20.4%), 627(15.5%), and 509(12.6%) by using FRS, mQRISK2 and QRISK2, whereas those eligible for statin therapy were maximum by mQRISK2 among 1323(32.7%) participants compared to QRISK2 (n = 1191; 29.4%) and FRS (n = 826; 20.4%) model. Krippendorff's alpha for mQRISK2 was in better agreement with body mass index (BMI) and lipid FRS CVD scoring system as compared to QRISK2 risk model.

CONCLUSION

CVD risk stratification based on smokeless tobacco use is first of its kind from this part of world and should be part of CV risk assessment.

Risk factors for non-communicable diseases in Bangladesh: findings of the population-based cross-sectional national survey 2018

OBJECTIVES

To determine the national prevalence of risk factors of non-communicable diseases (NCD) in the adult population of Bangladesh.

DESIGN

The study was a population-based national cross-sectional study.

SETTING

This study used 496 primary sampling units (PSUs) developed by the Bangladesh Bureau of Statistics. The PSUs were equally allocated to each division and urban and rural stratum within each division.

PARTICIPANTS

The participants were adults aged 18 to 69 years, who were usual residents of the households for at least 6 months and stayed the night before the survey. Out of 9900 participants, 8185 (82.7%) completed STEP-1 and STEP-2, and 7208 took part in STEP-3.

PRIMARY AND SECONDARY OUTCOME

The prevalence of behavioural, physical and biochemical risk factors of NCD. Data were weighted to generate national estimates.

RESULTS

Tobacco use was significantly (p<0.05) higher in the rural (45.2%) than the urban (38.8%) population. Inadequate fruit/vegetable intake was significantly (p<0.05) higher in the urban (92.1%) than in the rural (88.9%) population. The mean salt intake per day was higher in the rural (9.0 g) than urban (8.9 g) population. Among all, 3.0% had no, 70.9% had 1 to 2 and 26.2% had ≥3 NCD risk factors. The urban population was more likely to have insufficient physical activity (adjusted OR (AOR): 1.2, 95% CI: 1.2 to 1.2), obesity (AOR: 1.5, 95% CI: 1.5 to 1.5), hypertension (AOR: 1.3, 95% CI: 1.3 to 1.3), diabetes (AOR: 1.6, 95% CI: 1.6 to 1.6) and hyperglycaemia (AOR: 1.1, 95% CI: 1.1 to 1.1).

CONCLUSIONS

Considering the high prevalence of the behavioural, physical and biochemical risk factors, diverse population and high-risk group targeted interventions are essential to combat the rising burden of NCDs.

Effect of coconut oil on cardio-metabolic risk: A systematic review and meta-analysis of interventional studies

BACKGROUND AND AIMS

High total cholesterol (TC) and low density lipoprotein cholesterol (LDL-C) could be major risk factors for cardiovascular disease burden among high risk populations especially in South Asians. This systematic review and meta-analysis aimed to quantify the effects of coconut oil compared with other oils and fats on cardio-metabolic parameters.

METHODS

PubMed, Scopus and Web of Science were systematically searched. The main outcomes included are lipid and glycemic parameters. Subgroup analyses were performed to evaluate individual comparisons of vegetable oils and animal fat with coconut oil. Data were pooled using random-effects meta-analysis.

RESULTS

Coconut oil consumption significantly increased TC by 15.42 mg/dL (95% CI, 8.96-21.88, p < 0.001), LDL-C by 10.14 mg/dL (95% CI, 4.44-15.84, p < 0.001) and high density lipoprorein cholesterol (HDL-C) by 2.61 mg/dL (95% CI, 0.95-4.26, p = 0.002), and significantly decreased glycosylated hemoglobin (HbA1c) by 0.39 mg/dL (95% CI, -0.50 to -0.27, p < 0.001) but, it had no effects on triglycerides (TG), (4.25 mg/dL; 95% CI, -0.49-8.99, p = 0.08) when compared with the control group. Sub-group analysis demonstrated that coconut oil significantly increased TC and LDL-C over corn, palm, soybean and safflower oils and not over olive oil. Compared with butter, coconut oil showed a better pattern in cardio-metabolic markers by significantly increasing HDL-C (4.38 mg/dL, 95% CI, 0.40 to 8.36, p = 0.03) and decreasing LDL-C (-14.90 mg/dL, 95% CI, -23.02 to-6.77, p < 0.001).

CONCLUSIONS

Our results suggest that coconut oil consumption results in significantly higher TC, LDL-C and HDL-C than other oils. Consumption of coconut oil can be one of the risk factors for CVDs in South Asians.

Type D Personality and Myocardial Infarction: A Case-Control Study

BACKGROUND

Coronary heart disease (CHD) is an impending global pandemic in developed countries as well as developing countries and economies in transition, such as India. A significant increase in the incidence of myocardial infarction (MI), one of the most common types of CHD, is being reported in India, and the incidence and severity of the disease are more among the youth in Kerala. Studies assessing the association between psychological factors and MI are few in India.

METHODS

We adopted a case-control study design. A total of 150 cases (with MI) and 150 controls (without MI and matched for age and gender) from a tertiary care hospital in Trivandrum, Kerala, India, were selected using convenient sampling method, between September 2016 and August 2017.

RESULTS

As compared to 33.3% of the controls, 50.7% of patients with MI had type D personality characteristics. Multivariate logistic regression analysis after adjusting for the confounders indicated a positive and statistically significant association between type D personality and MI: OR = 4.14, 95% CI = 2.19-8.85, P = 0.003.

CONCLUSION

Type D personality is associated with MI.

Demographic & angiographic profile of young patients aged 40 year & less undergoing coronary angiography in a tier II city of Eastern India

BACKGROUND

Cardiovascular diseases (CVD) and its complications are on an increasing trend in the younger age group. In this study, we aimed to identify the different risk factor profile and coronary angiographic characteristics of young adults presenting with coronary artery disease.

METHODS

We conducted this retrospective observational study at Tata Main Hospital, Jamshedpur, Jharkhand, for 5 years between April 2015 and March 2020. Inclusion criteria being patients admitted for acute coronary syndrome or chronic stable angina, aged ≤40 years, who underwent coronary angiography. Those below 40 years of age who underwent angiography in non-CAD (coronary artery disease) setting were excluded.

RESULTS

Among the 117 cases included in this study, 81.1% were males and 18.8% were females. Majority of cases, i.e., 52.2% were in the age group of 36-40 years. Risk factor evaluation showed hypertension as the major risk factor, present in 30.76% of patients, followed by diabetes mellitus in 21.36%, Dyslipidaemia was noted in 7.6%. History of smoking was present in 8.54%, history of smokeless tobacco use was in 7.69%, family history of CAD was noted in 9.4% of patients. Among 117 cases, SVD (single-vessel disease) was most prevalent, seen in 55.5% cases. 21.3% had normal or recanalized coronaries. Among SVD, LAD (Left anterior descending artery) was the most commonly involved vessel (80%).

CONCLUSIONS

Young patients with CAD are mainly males, and SVD in the form of LAD is more commonly involved. In this vulnerable age group, more emphasis should be given on diagnosis and management of risk factors.

Profile of coronary artery disease in indian rural youth (< 35 yrs)

AIMS

To study the risk factors, clinical and angiographic profile of Indian rural youth (under 35yrs) presenting with Premature Coronary Artery Disease (PCAD).

SUBJECTS

and Methods: The PCAD registry had 1628 patients who were aged below 35 years, of which 681 patients satisfied the entry criteria. The data was analysed by statistical software R version 3.5.0.

RESULTS

The study enrolled 681 patients after satisfying the entry criteria. The mean age of patients was 30.85 years. There were 405 (59.5%) aged between 30 and 35 yrs, 205 (30.1%) between 25 and 30 yrs, 64 (9.4%) between 20 and 25 yrs and 7 (1.0%) were aged less than 20 yrs. Majority of them were males, 617 (90.6%). Nearly 411 (60.4%) were smokers, 56patients (8.2%) were diabetics and 97 (14.2%) were hypertensives. Around 441 (64.8%) patients had low HDL cholesterol levels and 218 (32.0%) had elevated triglyceride levels. Abdominal obesity was seen in 443 (65.1%) patients. Most common clinical presentation was ST elevation myocardial infarction (STEMI) seen in 536 (78.7%) patients. Around 40% patients had recanalized/non obstructive/thrombotic/normal coronaries on coronary angiogram.

CONCLUSIONS

Conventional risk factors such as smoking, low HDL levels and abdominal obesity play a major role in the causation of premature coronary artery disease among the rural youth. Thrombotic milieu in the coronaries was commonly noted in coronary angiograms. Lack of awareness, combined with urbanisation of rural lifestyle could be responsible for increasing incidence of premature coronary artery disease in rural youth.
