ABSTRACT

Background: The data on clinical characteristics, treatment practices and out comes in patients with Nonischemic 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. Keywords: Non-ischemic systolic heart failure, risk factors, outcomes, guideline directed treatment

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.
