Rheumatic heart disease

David I W Phillips, Clive Osmond, Martin L Williams, Alexander Jones
BACKGROUND: Chronic rheumatic heart disease (RHD) remains a globally important cause of heart disease. The reasons for the continuing high prevalence of this disease are obscure, but it may have its origins in the poor social and economic conditions with which the disease has been consistently and strongly linked. Mortality studies from the UK have suggested the importance of adverse environmental factors in early life; these studies demonstrated specific geographical associations between high rates of chest infection during infancy and subsequent RHD...

BACKGROUND: Pulmonary hypertension (PH) is a disease associated with a high morbidity and mortality. There is paucity of data regarding PH from the developing countries including India. Idiopathic pulmonary arterial hypertension is the most important etiological factor in the western world, but PH secondary to rheumatic heart disease, chronic obstructive pulmonary disease and untreated congenital heart disease could well be the predominant causes in developing countries like India. The main objective of the PROKERALA study - Pulmonary hypertension Registry Of Kerala is to collect data regarding the etiology, practice patterns and one-year outcomes of patients diagnosed to have PH...

OBJECTIVE: Atrial fibrillation is the most common sustained arrhythmia in patients with rheumatic heart disease (RHD). This study was conducted to determine the maintenance of sinus rhythm with amiodarone therapy following DC cardioversion (DCCV), early after successful balloon mitral valvuloplasty (BMV). METHODS: Patients were randomized to amiodarone group and placebo group and their baseline characteristics were recorded. DCCV was done 48h after BMV. After cardioversion, oral amiodarone was started initially 200mg three times a day for 2 weeks, then 200mg twice daily for two weeks followed by 200mg once daily for 12 months...

Cardiac surgeons traveling to East Africa on humanitarian surgical missions treat a large number of people of all ages with rheumatic heart disease. A patient with severe mitral stenosis with pulmonary edema in the second trimester of pregnancy was treated successfully with closed mitral commissurotomy in a hospital in rural Kenya. An operation from the late 1940s may regain prominence more than 70 years later in areas of the world with a high incidence of rheumatic heart disease and limited cardiology and cardiac surgery resources...

Rheumatic heart disease (RHD) is a serious cardiovascular disorder worldwide. Several articles have reported the effect of angiotensin I-converting enzyme gene insertion/deletion (ACE I/D) polymorphism in RHD risk. However, the results still remain inconsistent. The objective of this study was to assess more precise estimations of the relationship between ACE I/D variant and RHD susceptibility. Relevant case-control studies published between January 2000 and 2016 were searched in the electronic databases. The odds ratio (OR) with its 95% confidence interval (CI) was employed to calculate the strength of the effect...

OBJECTIVE: Rheumatic Heart Disease (RHD), a chronic acquired heart disorder results from Acute Rheumatic Fever. RHD is mostly prevalent in developing nations which is mainly diagnosed by transthoracic echocardiography. Till date, there is no biochemical marker for disease management. In the present study we aim to investigate whether mitral valve remodeling contributes to altered levels of circulating biomarkers of collagen metabolism in rheumatic heart disease. DESIGN AND METHOD: The study involved RHD subjects with before and after valve replacement surgery which includes age and sex matched controls...

It has been established that cell-free DNA circulating in the bloodstream affects cells. The characteristics of cfDNA depend on the physiological state of the organism. As we showed previously, diseases can cause either GC-enrichment of the cell-free DNA pool or its oxidation. Thus, in cases of cerebral atherosclerosis, heart attack and rheumatic arthritis the cell-free DNA pool is GC-enriched and, in the case of cancer, both GC-enriched and oxidized. Herein we investigated the time-dependent effect of oxidized and GC-rich cell-free DNA on NF-kB and NRF2 signaling pathways in human mesenchymal stem cells and showed that they affect cells in different ways...

Right atrial myxomas are rare. Its occurrence in a previously operated patient of rheumatic mitral stenosis posed clinical diagnostic challenge. We herein report a case of right atrial myxoma who had undergone mitral valve repair 20 years ago and now presented in congestive heart failure. The tumor was arising from the ostium of the coronary sinus and prolapsed into the right ventricle causing significant right ventricular inflow and outflow obstruction. Urgent repeat cardiac surgery was successfully performed to remove the tumor along with mitral valve replacement...

BACKGROUND: Acute rheumatic fever (ARF) and rheumatic heart disease (RHD) are responsible for a significant disease burden amongst Māori and Pacific populations in New Zealand (NZ). However, contemporary data are lacking regarding circulating group A Streptococcal (GAS) strains in NZ. Such information is important in guiding vaccine development. METHODS: GAS isolates from April to June 2015 were recovered from skin and pharyngeal samples from children living in areas of high social deprivation in Auckland, NZ, a significant proportion of which are Māori or Pacific...

Physicians and Internists in India have tended to brush under the carpet legal issues affecting their profession. Of concern to all Physicians is the judgment in a recent case where the NCDRC has stated that if MD Medicine Physicians write Physician & Cardiologist on their letterhead it is Quackery. What is MD Medicine degree holder in India qualified and trained to treat ? These are issues which need debate and that can only be initiated once we recognize that there is a problem. Either an MD Medicine is a cardiologist or he is not...

BACKGROUND: The cause of premature cardiovascular disease (CVD) in inflammatory rheumatic diseases (IRDs) has not been fully elucidated. As inflammation may play a role, we wanted to compare the occurrence and extent of inflammatory cell infiltrates (ICIs), small vessel vasculitis, and the amount of adipose tissue and collagen in cardiac biopsies taken from patients with coronary artery disease with and without IRDs. METHODS: From among the Feiring Heart Biopsy Study subjects, we selected patients undergoing coronary artery bypass grafting from whom paraffin-embedded, formalin-fixed specimens from the right atrium were available...

Rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE) are lifelong diseases with increased mortality and chronic pains. They are both characterized by immunological imbalances causing the immune system attack and destroy the bodies own tissues (called autoimmune disease). The best treatment, we are currently able to offer these patients, cause significant side-effects and can not prevent significant loss of quality of life. At the heart of the disease mechanisms in RA and SLE are subsets of immune cells called T and B cells...
