Utility of neutrophil-to-high-density lipoprotein-cholesterol ratio in patients with coronary artery disease: a narrative review.

The neutrophil-to-high-density lipoprotein-cholesterol ratio (NHR) is thought to reflect inflammatory status and dyslipidaemia, both of which play significant roles in coronary artery disease (CAD). The objective of this narrative review is to summarise the results of studies that have explored the utility of NHR for the diagnosis and management of CAD. The PubMed, Google Scholar, Scopus, Embase and Web of Science databases were searched for articles related to NHR from their inception to October 2022. Seven relevant articles were obtained for review. There were unclear relationships of NHR with age, sex, smoking status, hypertension and diabetes. However, NHR had a sensitivity and specificity as high as 94.8% and 59%, respectively, for the identification of significant coronary stenosis. NHR was also a superior predictor of prognosis to conventional parameters. NHR had a sensitivity and specificity as high as 77.6% and 74.2%, respectively, for the prediction of adverse events, including mortality, associated with acute coronary syndrome. Thus, NHR could be used in clinical cardiovascular medicine for risk stratification and the prediction of the short-term and long-term outcomes of CAD. However, more studies are required before a quantitative assessment of the efficacy of NHR for use in patient management can be completed.

Prevalence of rheumatic heart disease in South Asia: A systematic review and meta-analysis.

INTRODUCTION: Most countries in South Asia are endemic for rheumatic heart disease (RHD). We aimed to estimate the pooled prevalence of RHD in South Asia from population-based screening studies. METHODS: A systematic strategy was developed and used to search online databases for articles which described the prevalence of RHD in the South Asia region. Articles published in the English language between 1991 and 2021 were included in the review after fulfilling eligibility criteria. RESULTS: The pooled prevalence of RHD in South Asia was 2.79 per 1000 (95% Confidence interval (CI): 1.30-4.83) according to studies using auscultation followed by echocardiography of suspected cases and 18.28 per 1000 (95% CI: 11.59-26.44) for studies using echocardiography screening of all participants. The highest prevalence of 8.0 per 1000 (95% CI: 0.71-22.74) was observed in Pakistan, whereas the lowest prevalence of 0.32 per 1000 (95% CI: 0.18-0.48) was observed in Bangladesh. The prevalence of RHD has decreased to 2.30 per 1000 from 3.06 per 1000 by 24.84% in 30 years (1991-2021). The prevalence is more than twice higher using WHF criteria compared to WHO criteria. We observed no sex-related differences in prevalence (p = 0.16). CONCLUSIONS: The prevalence of RHD is still high in the South Asian population. Recent studies utilizing echocardiographic screening have identified subclinical cases of RHD, reflecting the significant burden of the disease in this region. More population-based echocardiography screening studies in every country in South Asia are required to estimate the accurate prevalence of the disease.

Contemporary Diagnosis and Management of Rheumatic Heart Disease: Implications for Closing the Gap: A Scientific Statement From the American Heart Association.

The global burden of rheumatic heart disease continues to be significant although it is largely limited to poor and marginalized populations. In most endemic regions, affected patients present with heart failure. This statement will seek to examine the current state-of-the-art recommendations and to identify gaps in diagnosis and treatment globally that can inform strategies for reducing disease burden. Echocardiography screening based on World Heart Federation echocardiographic criteria holds promise to identify patients earlier, when prophylaxis is more likely to be effective; however, several important questions need to be answered before this can translate into public policy. Population-based registries effectively enable optimal care and secondary penicillin prophylaxis within available resources. Benzathine penicillin injections remain the cornerstone of secondary prevention. Challenges with penicillin procurement and concern with adverse reactions in patients with advanced disease remain important issues. Heart failure management, prevention, early diagnosis and treatment of endocarditis, oral anticoagulation for atrial fibrillation, and prosthetic valves are vital therapeutic adjuncts. Management of health of women with unoperated and operated rheumatic heart disease before, during, and after pregnancy is a significant challenge that requires a multidisciplinary team effort. Patients with isolated mitral stenosis often benefit from percutaneous balloon mitral valvuloplasty. Timely heart valve surgery can mitigate the progression to heart failure, disability, and death. Valve repair is preferable over replacement for rheumatic mitral regurgitation but is not available to the vast majority of patients in endemic regions. This body of work forms a foundation on which a companion document on advocacy for rheumatic heart disease has been developed. Ultimately, the combination of expanded treatment options, research, and advocacy built on existing knowledge and science provides the best opportunity to address the burden of rheumatic heart disease.
