Heart failure in low- and middle-income countries: background, rationale, and design of the INTERnational Congestive Heart Failure Study (INTER-CHF).

BACKGROUND: Although heart failure (HF) has been referred to as a global epidemic, most HF information comes from high-income countries, with little information about low-income countries (LIC) and middle-income countries (MIC) in Africa, Asia, the Middle East, and South America, which make up the majority of the world's population. METHODS: The INTERnational Congestive Heart Failure Study is a cohort study of 5,813 HF patients enrolled in 108 centers in 16 LIC and MIC. At baseline, data were recorded on sociodemographic and clinical risk factors, HF etiology, laboratory variables, management, and barriers to evidence-based HF care at the patient, physician, and system levels. We sought to enroll consecutive and consenting patients ≥18 years of age with a clinical diagnosis of HF seen in outpatient clinics (2/3 of patients) or inpatient hospital wards (1/3 of patients). Patients were followed up at 6 and 12 months post-enrollment to record clinical status, treatments, and clinical outcomes such as death and hospitalizations. In the 5,813 enrolled HF patients, the mean age was 59 ± 15 years, 40% were female, 62% had a history of hypertension, 30% had diabetes, 21% had prior myocardial infarction, 64% were recruited from outpatient clinics, 36% lived in rural areas, and 29% had HF with preserved left ventricular ejection fraction. CONCLUSIONS: This unique HF registry aims to systematically gather information on sociodemographic and clinical risk factors, etiologies, treatments, barriers to evidence-based care, and outcomes of HF in LIC and MIC. This information will help improve the management of HF globally.

Expert panel opinion on adult pneumococcal vaccination in the post-COVID era (NAP- EXPO Recommendations-2024).

INTRODUCTION: Pneumococcal diseases pose a significant public health concern in India, with substantial morbidity and mortality, with the elderly and those with coexisting medical conditions being most at risk. Pneumococcus was also seen to be one of the main reasons for co-infection, pneumonia and complications in COVID. Current guidelines recommend vaccination for specific adult populations, but there is a lack of uniformity and guidance on risk stratification, prioritisation and optimal timing. METHODS: Nation Against Pneumococcal Infections - Expert Panel Opinion (NAP-EXPO) is a panel convened to review and update recommendations for adult pneumococcal vaccination in India. The panel of 23 experts from various medical specialties engaged in discussions and evidence-based reviews, discussed appropriate age for vaccination, risk stratification for COPD and asthma patients, vaccination strategies for post-COVID patients, smokers and diabetics, as well as methods to improve vaccine awareness and uptake. OUTCOME: The NAP-EXPO recommends the following for adults: All healthy individuals 60 years of age and above should receive the pneumococcal vaccine; all COPD patients, regardless of severity, high-risk asthma patients, post-COVID cases with lung fibrosis or significant lung damage, should be vaccinated with the pneumococcal vaccine; all current smokers and passive smokers should be educated and offered the pneumococcal vaccine, regardless of their age or health condition; all diabetic individuals should receive the pneumococcal vaccine, irrespective of their diabetes control. Strategies to improve vaccine awareness and uptake should involve general practitioners (GPs), primary health physicians (PHPs) and physicians treating patients at high risk of pneumococcal disease. Advocacy campaigns should involve media, including social media platforms. CONCLUSION: These recommendations aim to enhance pneumococcal vaccination coverage among high-risk populations in India in order to ensure a reduction in the burden of pneumococcal diseases, in the post-COVID era. There is a need to create more evidence and data to support the recommendations that the vaccine will be useful to a wider range of populations, as suggested in our consensus.

Knowledge and practice of radiation safety in the Catherization laboratory among Interventional Cardiologists - An online survey.

An Online Survey among Interventional Cardiologists (IC) assessed the knowledge (five questions) and practice of radiation safety (eleven questions). Out of 185 respondents, knowledge of annual radiation dose (2% knew), LAO cranial view giving maximum radiation (48%) and benefit of assessment of radiation exposure with dose area product (31%) was limited. Radiation safety was practiced "whenever I remember" in 37-59%. Radiation safety practices were optimal frame rate selection (32%), distancing from x-ray unit (17%), collimation use (30%), positioning the image detector close to chest (91%) and personal dosimeters use (40%). A major gap exists between knowledge and practice of radiation safety.

Clinical characteristics and 30-day outcomes in patients with acute decompensated heart failure: Results from Indian College of Cardiology National Heart Failure Registry (ICCNHFR).

BACKGROUND: Acute decompensated heart failure (ADHF) is a challenging medical emergency with high mortality and its prevalence is increasing in India. There is paucity of data on ADHF in the country. METHODS: Indian College of Cardiology National Heart Failure Registry (ICCNHFR) is an on-going observational registry on ADHF contributed by 22 hospitals across India; and we present the in-hospital and 30-day outcomes of ADHF patients enrolled from August 2018 to July 2019. Major objective included capturing demographics, comorbid conditions, aetiology, prescription patterns and assessing clinical outcomes. RESULTS: Of 5269 patients (mean age: 61.90 ± 13.85 years) enrolled in this study, males were predominant (67.09%). Mean duration of hospitalization was 5.74 ± 4.74 days. Ischemic heart disease was the most common (75.44%) aetiology. Abnormal electrocardiogram readings were found in most patients (89.86%). LVEF of ˂40% was found in 68.29% of patients. In-hospital mortality rates were 6.98%. The 30-day cumulative mortality was 12.35% and 30-day rehospitalization rate was 7.98%. At discharge, all guideline-based medical therapy (GDMT) were prescribed only to 24.99% of patients and 23.72% adhered to the prescription until 30 days. Older age, high serum creatinine levels and poor LVEF contributed to high mortality and rehospitalization. CONCLUSION: Patients with ADHF were younger and predominantly males. Usage of GDMT in ADHF patients was low (24.99%) and the in-hospital mortality was high. Older age, high serum creatinine levels, poor LVEF contributed for 30-day mortality and rehospitalization. This data on ADHF, could help in developing strategies to improve outcomes for HF patients in India.

Challenges in Management of Disseminated Melioidosis with Endocarditis in a Patient with Chronic Kidney Disease.

Melioidosis is a tropical infection that is increasingly being reported from South India. It is frequently observed in patients with diabetes mellitus, chronic ethanol consumption and chronic kidney disease (CKD). It presents commonly with pneumonia, deep seated abscesses or osteoarticular infections. Cardiac complications are very rare with endocarditis being reported in very few patients. We report the first case of endocarditis in melioidosis in India. Although infections are common in patients with CKD, melioidosis at the time of diagnosis of CKD has never been reported in the past. Our patient had multiple liver abscesses and endocarditis, and responded well to a 6 week course of ceftazidime and doxycycline, with the latter being continued for 20 weeks.
