A case report of pleuro-pericardial effusion in a patient on hemodialysis and a cardiac pacemaker.

There are multiple causes of pleuro-pericardial effusion (PPEF) and more so in a patient with end-stage renal disease (ESRD). Postcardiac injury syndrome (PCIS) is a loosely defined term for occurrence of pericardial and/or pleural effusion (PLEF), low-grade fever, with or without systemic upset, which occurs after myocardial infarction (MI), and other cardiac interventions. PPEF is one of its salient manifestations. We report occurrence of PCIS, presenting as pericardial effusion and massive PLEF, after insertion of cardiac pacemaker in a patient with ESRD, on maintenance hemodialysis (MHD). It was successfully managed with a short course of oral steroids.

Anomalous drainage of inferior vena cava into left atrium associated with ostium secundum atrial septal defect: a case report.

Background: Anomalous drainage of inferior vena cava (IVC) into left atrium (LA) is a rare aetiology of cyanosis in adults. This condition may be associated with atrial septal defects, anomalous pulmonary venous drainage, and pulmonary arteriovenous fistulas. This case report presents an instance of anomalous drainage of IVC into LA, associated with ostium secundum atrial septal defect (ASD). It contributes to the existing literature by highlighting the diagnostic challenges associated with this anomaly, particularly during surgical intervention. Case summary: A 38-year-old male presented with a six-year history of exertional dyspnoea and episodic palpitation. Transthoracic echocardiography revealed a large secundum (ASD), the IVC draining into LA, a left superior vena cava, and mild mitral regurgitation. These findings were further confirmed by right and left heart catheterization and CT angiogram. The patient was referred to CTVS department for surgical correction. The post-operative course was uneventful. At a 1.4-year follow-up, the patient reported significant improvement in symptoms. Discussion: We present a case of anomalous drainage of IVC into LA, associated with ostium secundum ASD. An ASD co-occurs with this condition in ∼70% of the reported cases. This anomaly differs from a low or inferior vena caval secundum ASD, where a prominent Eustachian valve can cause blood shunting from the IVC to LA. If the surgeon is not vigilant, this can be mistaken for the inferior ASD rim, potentially leading to iatrogenic diversion of IVC blood to LA upon ASD closure, resulting in cyanosis. This case underscores the diagnostic and surgical challenges associated with this condition.

Impact of capacity building and tele ECG based decision support on change in thrombolysis rate and inhospital and one year mortality in patients with STEMI, using hub and spoke model; multi-phasic intervention trial.

BACKGROUND: We report the impact of capacity building and teleconsultation on change in the thrombolysis rates and one-year mortality in patients with STEMI using a hub and the spoke model of STEMI care. METHODS: Twenty secondary care public hospitals were linked with a teaching hospital as a hub centre and the impact of the intervention on change in ischemic time, thrombolysis rates and all-cause in-hospital and one-year mortality was compared. RESULTS: 29 patients with STEMI were treated during pre-intervention from April 2020 to June 2020 and 255 patients during the post-intervention period from July 2020 to Oct 2021 in spoke centres. 245 patients were reported to a hub centre during the study period. The thrombolysis rate was significantly higher in the spoke centres after intervention (65.5%vs. 27.5 % p < 0.001) and was also significantly higher than in patients treated in a hub centre (65.5 % vs. 45.7 % p < 0.01). The in-hospital mortality was significantly lower in patients treated at spoke centres compared to those treated at the hub centre (7.8 % vs. 15.5 % < 0.003). The significant difference in mortality rate continued at one year (11.0 % vs.18.4 % p < 0.01). The median time from symptoms to thrombolytic therapy was significantly lower in STEMI patients treated in spoke centres compared to a hub centre (230 min vs. 356 min p < 0.001). CONCLUSION: The hub and spoke model of STEMI care is effective in increasing thrombolysis rate, and decreasing in-hospital and one-year mortality rate.

Epidemiological trends of RF/RHD in school children of Shimla in north India.

BACKGROUND & OBJECTIVES: There are no active surveillance studies reported from South East Asian Region to document the impact of change in socio-economic state on the prevalence of rheumatic fever/rheumatic heart disease (RF/RHD) in children. Therefore, we conducted a study to determine the epidemiological trends of RF/RHD in school children of Shimla city and adjoining suburbs in north India and its association with change in socio-economic status. METHODS: Active surveillance studies were conducted in 2007-2008 in urban and rural areas of Shimla, and 15145 school children, aged 5-15 yr were included and identical screening methodology as used in earlier similar survey conducted in 1992-1993 was used. The study samples were selected from schools of Shimla city and adjoining rural areas by multistage stratified cluster sampling method in both survey studies. After a relevant history and clinical examination by trained doctor, echocardiographic evaluation of suspected cases was done. An updated Jones (1992) criterion was used to diagnose cases of acute rheumatic fever (ARF) and identical 2D-morphological and Doppler criteria were used to diagnose RHD in both the survey studies. The socio-economic and healthcare transitions of study area were assessed during the study interval period. RESULTS: Time trends of prevalence of RF/RHD revealed about five-fold decline from 2.98/1000 (95% C.I. 2.24-3.72/1000) in 1992-1993 to 0.59/1000 (95% C.I. 0.22-0.96/1000) in 2007-2008. (P<0.0001). While the prevalence of ARF and RHD with recurrence of activity was 0.176/1000 and 0.53/1000, respectively in 1992-1993, no case of RF was recorded in 2007-2008 study. Prevalence of RF/RHD was about two- fold higher in rural school children than urban school children in both the survey studies (4.42/1000 vs. 2.12/1000) and (0.88/1000 vs. 0.41/1000), respectively. The indices of socio-economic development revealed substantial improvement during this interim period. INTERPRETATION & CONCLUSIONS: The prevalence of RF/RHD has declined by five-fold over last 15 yr and appears to be largely contributed by improvement in socio-economic status and healthcare delivery systems. However, the role of change in the rheumatogenic characteristics of the streptococcal stains in the study area over a period of time in decline of RF/RHD cannot be ruled out. Policy interventions to improve living standards, existing healthcare facilities and awareness can go a long way in reducing the morbidity and mortality burden of RF/RHD in developing countries.

Incidence, determinants, and outcomes of recovered left ventricular ejection fraction (LVEF) in patients with non-ischemic systolic heart failure; a hospital-based cohort study.

BACKGROUND: The data on incidence of recovered Left Ventricular Ejection Fraction (LVEF) and outcome in patients with non ischemic systolic heart failure is limited. We report the incidence, determinants and mortality in patients with recovered LVEF. METHODS: The 369 patients with HFrEF with LVEF of less than 40% of non ischemic etiology with available follow up echocardiography study at one year were enrolled. The baseline data of clinical characteristics and treatment was recorded prospectively and were followed up annually for mean of 3.6 years (range 2 to 5 years) to record all cause death and LVEF measured echocardiographically. The recovered, partially recovered and no recovery of LVEF was defined based on increase in LVEF to 50% and more, 41% to 49% and to persistently depressed LVEF to 40% or lower respectively. RESULTS: The LVEF recovered in 36.5%% of the cohort at 5 years. The rate of recovery of LVEF was slower in patients with no recovery of LVEF at one year compared to cohort with partially recovered LVEF (18% vs.53%) at five year. The Baseline LVEF was significantly associated with recovered LVEF, odd ratio (95% C.I.) 1.09(1.04, 1.14). The cumulative mortality at five years was significantly lower in cohort with recovered LVEF (18.1% vs. 57.1%). CONCLUSIONS: One third of the patients had recovered LVEF and was significantly associated with baseline LVEF and lower mortality rate.

Clinical characteristics, etiological profile, treatment and long term outcomes in patients with non ischemic systolic heart failure; Himachal Pradesh heart failure registry (HP-HF registry).

BACKGROUND: The data on clinical characteristics, treatment practices and out comes in patients with Non- ischemic Systolic Heart Failure (NISHF) is limited. We report clinical characteristics, treatment and outcomes in patients with NISHF. METHODS: 1004 patients with NISHF were prospectively enrolled and their demographics, clinical characteristics, and treatment were recorded systematically. Patients were followed annually for a median of 3 years (1 year to 8 years) for allcause death, major adverse cardiovascular events (MACE); composite of all-cause death, hospitalization of heart failure, and or for stroke. RESULTS: Patients of NISHF were middle-aged (58.8±16.2 years) population with severely depressed left ventricular ejection fraction (29.3±7.02%) and 31.1% had symptoms of advanced Heart failure. Hypertension (43.6%), obesity and or overweight (28.0%), Diabetes (15.0%), and valvular heart disease (11.8%) were the common risk factors. The guideline directed medical treatment was prescribed in more than 80% of the study cohort. Incidence of all cause death and MACE was 7 (6.8, 8.8) per 100 person years and 11(10, 13) per 100 person years respectively. The cumulative incidence of deaths and MACE was 35% (30%, 40%) and 49% (44%, 53%) at 8 years of follow-up. CONCLUSIONS: Patients of NISHF were middle-aged population with severely depressed LV systolic function with significant incident morbidity and mortality. Early detection of risk factors and their risk management and enhancing the use of guideline directed treatment may improve the outcomes.

Epidemiological study of hypertension in natives of Spiti Valley in Himalayas and impact of hypobaric hypoxemia; a cross-sectional study.

Hypertension is the result of interaction between genetic vulnerability and exposure to unhealthy lifestyle. However, studies investigating the impact of cardiovascular adaptive response to hypobaric hypoxia and extreme cold in natives of high altitude on the development of hypertension have yielded conflicting results. A community based cross-sectional study was carried out in an unique population of Spiti valley of Greater Himalayas residing at an altitude of 3100-3500 m (group 1) and 3500 m and above (group 2) to evaluate the impact of altitude of residence on prevalence of hypertension. 413 subjects, age 20 years and above were selected by stratified cluster random sampling technique and screened for recording socio-demographic profile, anthropometrics, fasting blood sugar and blood pressure. There was no significant difference in the mean age (40.1 vs.38.0 years) and gender distribution (65.7% vs. 61.4% females) between the two groups. The overall prevalence of hypertension was 22.5% and achieved higher significance in group 1 (27.5%) compared to group 2 (19%); p < 0.041. The socioeconomic profile and lifestyle of group from higher altitude was significantly different with people being less educated, agriculture as main occupation compared to the group at lower altitude. On comparison, the same group had a lower prevalence of obesity 17.4% vs. 35.9% (p < 0.000), Diabetes 0.4% vs. 4.1% (p < 0.03) and impaired fasting glucose 5% vs. 11.1% (p < 0.06). Obesity, age and altitude of residence were significantly associated as independent predictors of prevalence of hypertension in this study. Hypobaric hypoxia thus appears to have a protective effect from developing hypertension. The prevalence of hypertension in natives of Spiti valley is thus influenced by lifestyle related risk factors, age and possibly altitude of residence.

Role of omega 3 and omega 6 poly unsaturated fatty acids (PUFA) and vitamin D deficiency as risk determinants of metabolic syndrome in obesity: Worksite based case-control observational study.

BACKGROUND AND AIMS: Risk factors for metabolic syndrome among obese population are not clear. The role of Eicosapentaenoic acid (EPA), Arachidonic acid (AA) Poly Unsaturated Fatty Acids (PUFA), their ratio and vitamin D deficiency as risk factors of metabolic syndrome (MS) was explored in obese worksite workers. METHODS: The 145 obese worksite workers were enrolled and MS was diagnosed using adult treatment panel III criteria. The levels of EPA, AA PUFA were estimated using liquid chromatography-Mass Spectrometer and vitamin D levels with ELISA method. The association of MS with the tertiles of EPA, AA PUFAs, their ratio and vitamin D was estimated by calculating odds ratio and 95% C.I., taking lowest tertiles as the reference group using logistic regression model adjusted for age and gender. RESULTS: 105 out of 145 obese worksite workers; 72.4%, 95% C.I. (64.5%, 79.5%) had metabolic syndrome. The odd of MS was significantly lower in the group having highest tertiles of EPA 0.24 (0.09, 0.71) and was higher 2.0 (1.02, 3.89) in subjects with highest tertiles of AA: EPA ratio. The AA PUFA and vitamin D levels had no significant association with MS. CONCLUSION: The low levels of omega 3 PUFA (EPA) and elevated ratio of AA: EPA PUFA was significantly associated with MS in obese works site workers.

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.

Cardiac biomarker-based risk stratification algorithm in patients with severe COVID-19.

BACKGROUND AND AIMS: Cardiac biomarkers like cardiac troponins and natriuretic peptides are elevated in a substantial proportion of patients with coronavirus disease 2019 (COVID-19). We propose an algorithmic approach using cardiac biomarkers to triage, risk-stratify and prognosticate patients with severe COVID-19. METHODS: We systematically searched the PubMed and Google Scholar databases until May 31st, 2020, and accessed the available data on the role of cardiac biomarkers in patients with COVID-19. RESULTS: COVID-19 is associated with acute cardiac injury in around 7-28% of patients, significantly increasing its associated complications and mortality. Patients with underlying cardiovascular disease are more prone to develop acute cardiac injury as a result of COVID-19. The use of cardiac biomarkers may aid in differentiating the cardiac cause of dyspnea in patients with severe COVID-19. Cardiac biomarkers may also aid in triaging, risk-stratification, clinical decision-making, and prognostication of patients with COVID-19. However, there are concerns that routine testing in all patients with COVID-19 irrespective of severity, may result in unnecessary downstream investigations which may be misleading. In this brief review, using an algorithmic approach, we have tried to rationalize the use of cardiac biomarkers among patients with severe COVID-19. This approach is also likely to lessen the infection exposure risk to the cardiovascular team attending patients with severe COVID-19. CONCLUSION: It appears beneficial to triage, risk-stratify, and prognosticate patients with COVID-19 based on the evidence of myocardial injury and the presence of underlying cardiovascular disease. Future research studies are, however, needed to validate these proposed benefits.

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.

Transcoronary pacing: are the modern wires effective?

AIMS/OBJECTIVE: Coronary guide wires can be used for pacing the left ventricle during coronary angioplasty, however the experience with modern coronary guide wires as pacing wires is limited. The aim of this study was to determine the safety and efficacy of currently used coronary guide wires for transcoronary pacing. METHODS AND RESULTS: Transcoronary pacing was tested in 25 patients who were scheduled to undergo elective coronary angioplasty. Four different coronary guide wires were tested using an adaptive alligator clip connecting the guide wire to the pulse generator. Resistance of various guide wires was also measured ex vivo at 150, 175 and 190 cms from the tip respectively. BMW and Galeo wires were used in 12 and 11 patients respectively while Couger and Magic wire were used in one patient each. Pacing was successful in all patients with no pacing related complication. Most patients had unifocal ventricular ectopics. Mean threshold varied between 4 mA to 5.54 mA. Resistance varied from 12 ohms to 31 ohms depending upon the wire and distance from the tip. CONCLUSION: Transcoronary pacing using modern coronary guide wires appears to be dependable, well tolerated and safe temporary measure for significant bradyarrhythmias.

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.

Current status of rheumatic heart disease in India.

The rheumatic heart disease continues to be an important cause of disease burden in India, affecting the population in their prime and productive phase of the life. The prevalence of rheumatic heart disease is varied in different Indian studies, because of the inclusion of different populations at different point of times and using different screening methods for the diagnosis. The data on incidence and prevalence on a nationally represented sample are lacking. There is a need for establishing a population-based surveillance system in the country for monitoring trends, management practices, and outcomes to formulate informed guidelines for initiating contextual interventions for prevention and control of rheumatic heart disease.

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 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.

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.

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.
