![]() ![]() In its fully established form, diagnosis of RHD is relatively straightforward. ![]() RHD is the well-recognized complication of ARF. In the 2015 Revision of Jones Criteria, fever (≥38.5☌), ESR ≥60 mm in the first hour and/or CRP ≥3.0 mg/dL for low-risk populations, and fever (≥38☌), ESR ≥30 mm/h and/or CRP ≥3.0 mg/dL for moderate- and high-risk populations have been included as minor criteria for ARF.10 Monoarthralgia, in this population, has been a minor manifestation. On the hand, polyarthralgia has been recognized as a major manifestation only in moderate- or high-incidence populations and only after careful consideration and exclusion of other causes of arthralgia such as autoimmune, viral, or reactive arthropathies (class IIb level of evidence C). The 2012 Australian guideline considers aseptic mono-arthritis or polyarthralgia as a major manifestation in place of polyarthritis when alternative diagnoses have been carefully excluded.8 In the recently published 2015 AHA guideline10, monoarthritis has been considered to be part of the ARF spectrum in patients from moderate- to high-risk populations (class I level of evidence C). Of ARF in selected high-risk populations. Subsequent observations indicate that, aseptic monoarthritis may also be important as a clinical manifestation Arthralgia has been recognized as a minor criterion. Typically, the arthritis of ARF is a migratory polyarthritis, involving the large joints e.g. For pathological aortic regurgitation, again all 4 criteria to be met: seen in at least 2 views, jet length ≥1 cm in at least 1 view, peak velocity >3 m/s, and pan-diastolic jet in at least 1 envelope.10 Globally, RHD remains the most-common cardiovascular disease (CVD) in young people aged 3 m/s, and pan-systolic jet in at least 1 envelope. During the experimental phase of this work, acceptable results of sensitivity and specificity were obtained, reason why as future work it is planned its development as a tool of low cost to optimize the detection of valvular diseases.Īcute rheumatic fever (ARF) and consequent rheumatic heart disease (RHD) are important public health issues in developing countries, and marginalized people of some developed countries. ![]() The evaluation of the presence of a valvular lesion consisted in the identification of abnormalities in the relationship between the period of contraction and relaxation of the cardiac cycle. Based on this situation, this document describes a proposal focused on the analysis and processing of the auscultated heart signal in order to generate a presumptive diagnosis of heart murmurs. Furthermore, in public health systems it is not possible to meet the demand of patients who require the use of these new technologies, so auscultation is key in the process of evaluating cardiac subjects. The development of innovative cardiac assessment techniques has optimized heart conditions diagnosis, however it has led to a reduction of auscultation practice and hence its effectiveness. ![]()
