Long term outcomes in patients with RF/RHD: Eight-year follow-up of HP-RF/RHD (Himachal Pradesh Rheumatic Fever/Rheumatic Heart Disease) registry in a Northern Indian state.

BACKGROUND: The long-term outcome data in patients with rheumatic fever/rheumatic heart disease (RF/RHD) is limited. We report the cumulative incidence of adverse outcomes in a cohort of RHD patients from a northern state of India at a median follow-up of 5.4 years. METHODS: 1714 patients with RF/RHD diagnosed using clinical and echocardiographic criteria were registered from 2011 to 2018, and their baseline clinical characteristics and treatment practices were recorded. Patients were followed up annually for a median of 5.4 years (range 1-8 years) for incident adverse outcomes. The cumulative incidence of adverse composite outcomes, all-cause mortality, hospitalization for heart failure, stroke, and/or peripheral embolism was estimated. The baseline clinical characteristics were explored to identify the potential risk predictors using a multivariate cox proportional hazard model. RESULTS: The cumulative incidence of adverse composite outcomes was 17.1% (15.3%-19.0%) at a median follow-up of 5.4 years. The predictors for the adverse composite outcomes (hazard ratio, 95% confidence interval) were age (1.03, 1.02-1.04), education status below primary level (1.60, 1.23-2.05), severe valvular heart disease (1.74, 1.36-2.23), NYHA class III/IV at enrollment (1.56, 1.18-2.07), right heart failure (4.48, 2.85-6.95), history of stroke and/or peripheral embolism (3.7, 1.5-9.2) and mitral balloon valvuloplasty (0.62, 0.40-0.96). CONCLUSIONS: The incidence of adverse outcomes is substantial in patients with RF/RHD. Thus, early detection of high-risk patients and their risk management is needed to improve outcomes.

Gender differences in the epidemiology of Rheumatic Fever/Rheumatic heart disease (RF/RHD) patient population of hill state of northern India; 9 years prospective hospital based, HP-RHD registry.

OBJECTIVES: We report the gender-based differences in the prevalence, severity, pattern of valvular involvement, and complications in patients with Rheumatic Fever/Rheumatic heart disease (RF/RHD). METHODS: The 2475 consecutive patients with RF/RHD diagnosed using clinical and echocardiographic criteria were registered prospectively from January 2011 till December 2019. The association of gender with the pattern of valvular involvement, nature, and severity of valvular dysfunction and cardiovascular complications was analyzed using a logistic regression model, and odds ratios with 95% CI were estimated. RESULTS: The mitral and tricuspid valve involvement was significantly lower in the male gender, odds ratio with 95% CI of 0.55 (0.44-0.61), and 0.69 (0.58-0.83) respectively, while the aortic valve was affected more frequently than females, odds ratio 1.36 (1.14-1.62). The severity of valvular disease had no significant association with gender, 0.99 (0.82-1.20). The association between gender and cardiovascular complications, heart failure, stroke, and atrial fibrillations were not statistically significant. The prevalence of RF/RHD was more than two-fold higher in female gender than male (71.4% vs. 29.6%, p < 0.0001). CONCLUSIONS: RF/RHD is more prevalent in females. Gender has a significant association with the pattern of valvular involvement. The severity of valvular dysfunction and cardiovascular complications had no significant association with gender.

Prevalence and risk determinants of metabolic syndrome in obese worksite workers in hill city of Himachal Pradesh, India.

OBJECTIVE: We report prevalence and risk factors of metabolic syndrome (MS) in the obese workforce of organized sector in hill city of Himachal Pradesh (HP), India. METHODS: The cross-sectional survey study of employees of organized sectors in Shimla city of HP, India, was conducted to collect data of demographics, health behavior, psychosocial factors, anthropometry, blood pressure, and blood chemistry to measure blood glucose and lipid profile in fasting state in 3004 employees using validated tools. Out of 3004 subjects screened, data of 418 subjects with body mass index of ≥30 are analyzed to estimate the prevalence of MS and its risk determinants. The association of demographics, health behavior, and psychosocial factors as the risk determinants were analyzed using multivariable logistic regression modeling. RESULTS: MS was prevalent in 57.6% [95% confidence interval (CI): 52.8%-62.3%]. The central obesity (odds ratio: 10.6, 95% CI: 2.32-48.4) and consumption of frequent or daily alcohol (odds ratio: 1.94, 95% CI: 1.05-3.59),and extra salt (odds ratio: 3.34, 95% CI: 1.09-10.2) were independent risk factors for MS. The consumption of tobacco, vegetables, sugar-sweetened drinks, physical inactivity, and psychosocial factors had no significant association with MS in obese population. CONCLUSIONS: MS is highly prevalent among obese employees of organized sector. The consumption of alcohol and extra salt were major behavioral risk factors for MS and therefore have important implications in behavioral modifications for prevention of MS among obese employees in organized sectors.

Epidemiological trends of acute coronary syndrome in Shimla district of the hilly state of Northern India: Six-year data from the prospective Himachal Pradesh acute coronary syndrome registry.

OBJECTIVES: The epidemiological trends of incidence, treatment practices, and outcomes are reported from Shimla district of the northern state of India. METHODS: The data of clinical characteristics, treatment practices, and outcomes of patients with acute coronary syndrome (ACS) diagnosed using standard criteria were collected systematically from the defined hilly geographical region of the northern state of India from January 2013 to December 2018 as the part of Himachal Pradesh acute coronary syndrome (HP ACS) registry. The year-wise trends of incidence, demographic, clinical characteristics, treatment practices, and in-hospital mortality are reported. RESULTS: The incidence of ACS shows declining trends. The mean age at incident ACS is increasing without change in gender predilection. The prevalence of overweight/obesity and diabetes has increased significantly since 2013 but tobacco consumption has not changed. The reperfusion therapy has increased significantly (20.9% in 2013 to 42.1% in 2018, p < 0.01) primarily because of an increased use of percutaneous coronary angioplasty. There is a trend of increasing use of beta blockers. The use of other oral secondary preventive drugs remained more than 90% since 2013. The in-hospital mortality rate is declining (9.0% in 2013 to 6.0% in 2018, p < 0.01). CONCLUSIONS: Epidemiological characteristics of the ACS population in Shimla district are changing. The trends of use of reperfusion therapy in ST segment elevated myocardial infarction population has although increased but is still suboptimal, and there is a need for taking initiatives both at the system and population level to improve the reperfusion therapy.

School-based surveillance for detection of children with acute pharyngitis, rheumatic fever/rheumatic heart disease in Shimla district, Himachal Pradesh, India-A cluster randomized controlled trial.

BACKGROUND: The lack of surveillance system is a major barrier in prevention and control of rheumatic fever/rheumatic heart disease (RF/RHD). Efficacy of school-based surveillance was evaluated for detection of acute pharyngitis and RF/RHD in Shimla district, HP. METHODS: The schools in district Shimla were randomly assigned to intervention and controlled arm (442 vs. 441 schools). The trained nodal teachers reported children with symptoms of acute pharyngitis and or RF/RHD in intervention arm and children taken to hospitals by parents for symptoms of acute pharyngitis and or RF/RHD under control arm through mobile phone to coordinating centre. Final outcome for presence of RF/RHD or other heart Diseases was recorded after examination at nearest primary health centers and/or at Indira Gandhi Medical College Hospital, Shimla. Difference in detection rate between intervention arm and control arm was compared using Z test. RESULTS: The number of school children reported from intervention group was significantly higher than in control due to suspected symptoms of acute pharyngitis and or RF/RHD were 65 (2.84/1000) and 15 (0.60/1000), respectively (p < 0.01). Only 4 children in each arm were found to have heart diseases, with prevalence of (0.17/1000 and 0.16/1000), respectively, after clinical and echocardiography evaluation. In intervention arm, one child had RHD while three had congenital heart disease; in control arm, one child had congenital heart disease and three had RHD. CONCLUSIONS: School based surveillance had higher rate of suspecting children with acute pharyngitis and or RF/RHD although with low specificity. There is a need of future studies to demonstrate the effectiveness of the proposed intervention in endemic regions of the state.

Prevalence, risk determinants and consequences of atrial fibrillation in rheumatic heart disease: 6 years hospital based-Himachal Pradesh- Rheumatic Fever/Rheumatic Heart Disease (HP-RF/RHD) Registry.

OBJECTIVE: To report the prevalence, risk factors and consequences of atrial fibrillation (AF) in patients of rheumatic heart disease (RHD). METHODS: The Himachal Pradesh- Rheumatic Fever/Rheumatic Heart Disease (HP-RF/RHD) Registry database of 1918 patients was analyzed. AF was diagnosed with 12-lead ECG recording at entry in to the registry. The association of AF with nature and severity of valvular dysfunction was analyzed, adjusted for age, left atrial (LA) dimension and pulmonary arterial hypertension using multivariable logistic regression model and strength of association was reported as odds ratio (OR) with 95% confidence intervals (C. I.). RESULTS: The study population consisted of young (40.2 ±â€¯14.3 years), predominantly females (72.3%) from rural area (94.1%). Prevalence of AF was 23.9% (95% C. I. 22.1%-25.8%). The independent determinants AF were age (OR 1.04, 95% C.I. 1.03-1.06), LA size (OR 1.10, 95% C.I. 1.08-1.11). The association of AF with age, New York Heart Association functional class, mitral stenosis severity and tricuspid regurgitation was statistically significant and graded. Mitral regurgitation and aortic valve disease had no significant independent association with AF. The prevalence of heart failure, stroke, peripheral embolism and mortality was significantly higher among patients with AF (p < .01). CONCLUSION: AF is common in RHD patients and is significantly associated with heart failure and systemic thromboembolism. Age, mitral stenosis severity, tricuspid regurgitation and LA size were independently associated with AF.

Prevalence, risk factors, and significance of iron deficiency and anemia in nonischemic heart failure patients with reduced ejection fraction from a Himachal Pradesh heart failure registry.

BACKGROUND: The study aimed to estimate the prevalence, risk determinants, and its clinical significance of iron deficiency and anemia in patients of nonischemic heart failure with reduced ejection fraction (HFrEF). METHODS: Serum ferritin, transferrin saturation, and the hemoglobin (Hb) levels were measured in 226 consecutive patients with HFrEF diagnosed based on the left ventricular ejection fraction ≤ 45% and absence of coronary artery luminal narrowing of more than 50%, in a prospective tertiary care hospital-based heart failure registry. Patients with the New York Heart Association functional class III/IV were classified as patients with advanced heart failure. Multivariable logistic regression modeling was performed to assess the risk determinants of iron deficiency and anemia and their clinical significance as the risk factors for advanced heart failure. Odds ratio with 95% confidence interval (CI) was reported as the estimates of the strength of association between exposure and outcome variables. RESULTS: Iron deficiency and anemia were prevalent in 58.8% (52.2%-65.1%) and 35.8% (29.8%-42.3%) of patients, respectively. Female gender [OR 3.5 (95% CI 1.9-6.5)], history of bleeding [OR 11.7 (95% CI 1.4-101.2)], and vegetarian diet [OR 2.5 (95% CI 1.4-4.6)] were significantly associated with iron deficiency, while diabetes [OR 3.0 (95% CI 1.40-6.5)], estimated glomerular filtration rate [OR 0.98 (95% CI 0.97-0.99)], history of bleeding [OR 13.0 (95% CI 2.3-70.9)], and female gender [OR 2.9 (95% CI 1.5-5.7)] had significant association with anemia. The Hb level (OR 0.82 (95% CI 0.70-0.96) and transferrin saturation (OR 0.98 (95% CI 0.96-0.99)] had a significant inverse association with symptoms of advanced heart failure. CONCLUSION: Iron deficiency and anemia are common comorbidities associated with HFrEF. Low Hb and transferrin saturation are significantly associated with advanced heart failure. The findings have important implications in the management of heart failure.

Clinical Characteristics, Complications, and Treatment Practices in Patients With RHD: 6-Year Results From HP-RHD Registry.

BACKGROUND: Despite the high prevalence of rheumatic heart disease (RHD) in developing countries such as India, data on characteristics, complications, and treatment practices are lacking. The HP-RHD (Himachal Pradesh Rheumatic Heart Disease) registry aimed at reporting these parameters in patients with RHD from a northern state of India. METHODS: A total of 2,005 consecutive patients of RHD were enrolled over a period of 6 years (2011 to 2016) in the present study. The clinical characteristics, complications, and treatment practices were systematically recorded. RESULTS: The mean age for patients with RHD was 40.3 ± 14.3 (range 5 to 83 years). RHD predominantly affected females (72.3%) and population from rural background (92%). Multivalvular involvement was frequent (43.2%), mitral valve was the commonest affected valve (83.3%). The majority of the patients had moderate-to-severe valvular dysfunction (69.3%). Mitral and tricuspid valve involvement was more frequent in female subjects compared with more frequent aortic valve involvement in male subjects (p < 0.001). The major adverse cardiovascular events were recorded in 23.4% patients at the time of registry and comprised mainly advanced heart failure (15.6%), peripheral embolism (4.1%), and stroke (3.9%). The independent risk determinants of major adverse cardiovascular events (were advanced age (odds ratio [OR]: 1.01; 95% confidence interval [CI]: 1.00-1.02), severe mitral stenosis (OR: 1.73; 95% CI: 1.34-2.20), severe tricuspid regurgitation (OR: 2.11; 95% CI: 1.48-3.02), presence of pulmonary artery hypertension (OR: 1.33; 95% CI: 1.04-1.69), and atrial fibrillation (OR: 1.64; 95% CI: 1.28-2.11). Evidence-based use of oral anticoagulant therapy was documented in 77.7% of high-risk patients. Only 28.5% of study population was receiving secondary prophylaxis. CONCLUSIONS: Complications in patients with RHD increase with age and worsening valvular dysfunction. Programs focused on early detection and evidence-based management will assist in improving outcomes.

Gender differences in the management of acute coronary syndrome patients: One year results from HPIAR (HP-India ACS Registry).

INTRODUCTION: Data from high-income countries suggest that women receive less intensive diagnostic and therapeutic management than men for acute coronary syndrome (ACS). There is a paucity of such data in the Indian population, which is 69% rural and prior studies focused mostly on urban populations. The objective of the present study was to identify the gender based differences in ACS management, if any, in a predominantly rural population. METHODS: Data from 35 hospitals across Himachal Pradesh covering >90% of state population were collected for one year (July 2015-June 2016). A total of 2118 ACS subjects met inclusion criteria and baseline characteristics, in-hospital treatments and mortality rates were analyzed. RESULTS: Women constituted less than one-third of ACS population. Women were older compared to men and were more likely to present with NSTEMI/UA. Misinterpretation of initial symptoms and late presentation were also common in women. Fewer women received optimal guideline based treatment and PCI (0.9% vs 4.2%, p<0.01). Compare to men, women more often had Killip class >1 (27.3% vs 20.4%, p<0.01) and higher in-hospital mortality (8.5% vs 5.6%, p=0.009). On multivariate analysis the association between female gender and mortality was attenuated (adjusted odds ratio [OR]=1.36 [0.77-2.38]). CONCLUSION: The present study from India, is the first of its kind to evaluate the gender based differences among ACS patients, in a predominantly rural population. Our analysis demonstrates a significant gender based difference between symptom awareness and delay in presentation, management and in-hospital outcome. Further studies are warranted across other parts of country to investigate this gender disparity.

Multicenter HP ACS Registry.

BACKGROUND: No population representative data on characteristics, treatment, and outcome were available in acute coronary syndrome (ACS) patients. METHODS: The clinical characteristics, treatment, and in-hospital outcome of 5180 ACS patients registered in multicenter ACS Registry across 33 hospitals in the state since January 2012 to December 2014 are reported. ACS was diagnosed using standard criteria. RESULT: 70.8% were men; mean age was 60.9±12.1. NSTEMI was more frequent than STEMI (54.5% vs. 45.5%). 83.3% of the ACS population were from rural area. Pre-hospital delay was long, with a median of 780min. 35.6% of STEMI patients received thrombolytic therapy. Evidence-based treatment was prescribed in more than 80% of ACS patients, and the treatment was similar in men and women across all types of health care centers. In-hospital mortality was 7.6%, and was more frequent in STEMI than in NSTEMI (10.8% vs. 5.0%, p<0.001). INTERPRETATION: Pre-hospital delay was long, and use of reperfusion therapy was significantly lower. The in-hospital death rates are higher.
