RESUMO

BACKGROUND: Based on the inclusion criteria of clinical trials, the degree of cervical carotid artery stenosis is often used as an indication for stent placement in the setting of extracranial carotid atherosclerotic disease. However, the rigor and consistency with which stenosis is measured outside of clinical trials are unclear. In an agreement study using a cross-sectional sample, we compared the percent stenosis as measured by real-world physician operators to that measured by independent expert reviewers. METHODS: As part of the carotid stenting facility accreditation review, images were obtained from 68 cases of patients who underwent carotid stent placement. Data collected included demographics, stroke severity measures, and the documented degree of stenosis, termed operator-reported stenosis (ORS), by 34 operators from 14 clinical sites. The ORS was compared with reviewer-measured stenosis (RMS) as assessed by 5 clinicians experienced in treating carotid artery disease. RESULTS: The median ORS was 90.0% (interquartile range, 80.0%-90.0%) versus a median RMS of 61.1% (interquartile range, 49.8%-73.6%), with a median difference of 21.8% (interquartile range, 13.7%-34.4%), P<0.001. The median difference in ORS and RMS for asymptomatic versus symptomatic patients was not statistically different (24.6% versus 19.6%; P=0.406). The median difference between ORS and RMS for facilities granted initial accreditation was smaller compared with facilities whose accreditation was delayed (17.9% versus 25.5%, P=0.035). The intraclass correlation between ORS and RMS was 0.16, indicating poor agreement. If RMS measurements were used, 72% of symptomatic patients and 10% of asymptomatic patients in the population examined would meet the Centers for Medicare and Medicaid Services criteria for stent placement. CONCLUSIONS: Real-world operators tend to overestimate carotid artery stenosis compared with external expert reviewers. Measurements from facilities granted initial accreditation were closer to expert measurements than those from facilities whose accreditation was delayed. Since decisions regarding carotid revascularization are often based on percent stenosis, such measuring discrepancies likely lead to increased procedural utilization.

RESUMO

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is one of the leading causes of mortality worldwide and contributes considerably to morbidity and health care costs. In October 2014, the Centers for Medicare and Medicaid Services introduced financial penalties followed by bundled payments for care improvement initiatives in patients hospitalized with COPD. OBJECTIVES: This study seeks to evaluate whether an evidence-based interprofessional COPD care bundle focused on inpatient, transitional, and outpatient care would reduce hospital readmission rates. METHODS: A pre- and postintervention analysis comparing readmission rates after a hospitalization for COPD in subjects who received standard of care versus an interprofessional team-led COPD care bundle was conducted. The primary outcome was 30-day all-cause readmissions; secondary outcomes included 60- and 90-day all-cause readmissions, escalation of pharmacotherapy, interprofessional interventions, and hospital length of stay. RESULTS: A total of 189 subjects were included in the control arm and 127 subjects in the COPD care bundle arm. A reduction in 30-day all-cause readmissions between the control arm and COPD care bundle arm (21.7% vs. 11.8%, P = 0.017) was seen. Similar outcomes were seen in 60-day (18% vs. 8.7%, P = 0.013) and 90-day all-cause readmissions (19.6% vs. 4.7%, P < 0.001). Pharmacists consulted with 68.5% of subjects and assisted with access to outpatient medications in 45.7% of subjects in the COPD care bundle arm. An escalation in maintenance therapy occurred more often in the COPD care bundle arm (22.2% vs. 44.9%, P < 0.001) than the control arm. CONCLUSIONS: An interprofessional team-led COPD care bundle resulted in significant reductions in all-cause hospital readmissions at 30, 60, and 90 days.

RESUMO

Student veterinary nurses (SVNs) in the United Kingdom can spend over half their training time within the clinical learning environment (CLE) of a training veterinary practice before achieving clinical competency. Sociocultural complexities and poor management within the CLE may have a significant impact on the learning experiences of SVNs, as has been found in studies involving student human nurses. The aim of this research was to develop and validate the SVN CLE Inventory (CLEI) using principal component analysis (PCA), via a cross-sectional design, based on inventories already established in human nursing CLEs. The SVN CLEI was distributed to SVNs via an online survey over a 3-month period, generating 271 responses. PCA resulted in a valid and reliable SVN CLEI with 25 items across three factors with a total variance explained of 61.004% and an overall Cronbach's alpha (α) of .953 (factor 1: clinical supervisor support of learning [α = .935]; factor 2: pedagogical atmosphere of the practice [α = .924]; factor 3: opportunities for engagement [α = .698]). Gaining student feedback is a requirement set out by the Royal College of Veterinary Surgeons Standards Framework for Student Veterinary Nurse Education and Training, and the SVN CLEI can be used to complement the current evaluation of the training veterinary practice CLE. This will facilitate development of a more comparable, consistent, and positive experience for SVNs during clinical training in the UK.

RESUMO

Student veterinary nurses (SVNs) spend a significant proportion of their training time within the clinical learning environment (CLE) of a veterinary practice. These clinical experiences are vital for building practical and professional skills. To evaluate the current satisfaction of SVNs in the CLE, a cross-sectional survey design was used incorporating a previously validated instrument. To provide understanding of factors that may affect the SVN satisfaction, additional validated tools were added across factors, including resilience, wellbeing, personality, and work place belonging. A total of 171 SVNs completed the survey. In addition, two open questions were included to provide greater depth of understanding of the SVN experiences. Results showed that 70.76% of respondents were satisfied/very satisfied with the CLE. Significant factors that affected the satisfaction scores included, depression, anxiety, and stress (p ≤ .001), psychological sense of organizational membership (p ≤ .001), agreeableness (p = .022), and emotional stability (p = .012). The qualitative data demonstrated shared SVN factors that are considered to contribute to clinical learning and those that detract from clinical learning. Educational facilities and training veterinary practices can support the SVN within the CLE by creating a greater sense of belonging, considering the SVN individual personality and wellbeing, and including the SVN in discussions around learning support needs.

RESUMO

BACKGROUND: Intersocietal Accreditation Commission (IAC) accreditation is granted or delayed depending on the fulfillment of several quality metrics. Investing in up-to-date equipment might reflect a commitment to quality. METHODS: Data from echocardiography (n = 3079) and nuclear cardiology (n = 1835) accreditation applications submitted between 2012 and 2014 were evaluated to determine the mean age of laboratory equipment. Laboratory quality was assessed by the number of missing quality metrics, and a composite quality score was calculated as the sum of missing quality metrics. A lower score thus represented better laboratory quality. The relationship between equipment age and quality was explored as an interaction term between equipment age and the composite quality score and was incorporated into regression models for prediction of accreditation status. RESULTS: During the study period, 49% of echocardiography and 42% of nuclear laboratories were granted accreditation without delay. For both echocardiography and nuclear laboratories, there was a statistically significant trend toward an increasing number of missing quality metrics with increasing quartiles of equipment age. The interaction between equipment age and the composite quality score was a significant predictor of delay of accreditation for both echocardiography and nuclear cardiology laboratories, with a stronger association for 1st-time applicants. Among sites applying for accreditation in both modalities simultaneously, accreditation in one modality predicted the accreditation decision for the other. CONCLUSIONS: Laboratory quality is an important determinant of IAC accreditation, and equipment age is an effect modifier of this relationship. Contemporary equipment likely reflects a commitment to quality, for both echocardiography and nuclear laboratories.

RESUMO

BACKGROUND: The aim of this study was to evaluate reporting compliance of laboratories applying for serial accreditation by the Intersocietal Accreditation Commission (IAC) and compare compliance based on laboratory characteristics. METHODS: All laboratories applying for IAC accreditation for the first time in 2008 and then twice more (2011-2014) were evaluated for compliance with 18 reporting elements. The elements were ranked into three severity groups (high/moderate/low). RESULTS: Reports from 523 laboratories were evaluated. The percentage of laboratories with reporting issues by cycle was 66.2% for cycle 1, 36.7% for cycle 2, and 43.8% for cycle 3 (p < .001). For most of the 18 elements, there was a significant decrease in the percentage of labs with issues. Less moderate and high severity errors were seen over time. Also, the mean non-compliant elements per laboratory decreased from 5.78 ± 2.72 at cycle 1, down to 1.25 ± 1.77 at cycle 3. CONCLUSIONS: In facilities applying for 3 consecutive IAC accreditation cycles, reporting compliance with IAC Standards improved between cycles 1-2 and 1-3. No significant improvement occurred between cycles 2-3. Although the quality of reports improved overall, problems remain in quantifying myocardial perfusion defects, documenting report approval date, and integrating stress and imaging reports.

RESUMO

BACKGROUND: In 2011, Tilkemeier et al reported significant nuclear cardiology laboratory noncompliance with reporting standards. The aim of this study was to identify and examine noncompliant reporting elements with the Intersocietal Accreditation Commission Nuclear/PET (IAC) Reporting Standards and to compare compliance between 2008 and 2014. METHODS: This was a retrospective study of compliance with 18 reporting elements utilizing accreditation findings from all laboratories applying for accreditation in 2008 and 2014. RESULTS: 1816 labs applying for initial or subsequent accreditation were analyzed for compliance. The mean reporting noncompliance per lab decreased from 2008 to 2014 (2.48 ± 2.67 to 1.24 ± 1.79, P < .001). Noncompliance decreased across lab types, labs with Certification Board of Nuclear Cardiology physicians on staff, and by geographic region (P < .001). Overall severity of reporting issues decreased. Facilities with compliant reports increased from 35.0% in 2008 to 57.1% in 2014 (P < .001). CONCLUSION: Continuing medical education, accreditation, and other instructional activities aimed at improving nuclear cardiology reporting appear to have made a positive impact over time with the number and severity of noncompliance decreased. More labs are now compliant with the IAC Standards and, thus, reporting guidelines. However, the need for continued educational efforts remains.

RESUMO

OBJECTIVES: Accreditation of echocardiographic testing facilities by the Intersocietal Accreditation Commission (IAC) is supported by the American College of Cardiology and American Society of Echocardiography. However, limited information exists on the accreditation status and geographic distribution of echocardiographic facilities in the United States. Our study aimed to identify (1) the proportion of outpatient echocardiography facilities used by Medicare beneficiaries that are IAC accredited, (2) their geographic distribution, and (3) variations in procedure type and volume by accreditation status. METHODS: As part of the VALUE-ECHO (Value of Accreditation, Location, and Utilization Evaluation-Echocardiography) study, we examined the proportion of IAC-accredited echocardiographic facilities performing outpatient echocardiography in the 2013 Centers for Medicare and Medicaid Services outpatient limited data set (100% sample) and their geographic distribution using geocoding in ArcGIS (ESRI, Redlands, CA). RESULTS: Among 4573 outpatient facilities billing Medicare for echocardiographic testing in 2013, 99.6% (n = 4554) were IAC accredited (99.7% in the 50 US states and 86.2% in Puerto Rico). The proportion IAC-accredited echocardiographic facilities varied by region, with 98.7%, 99.9%, 99.9%, 99.5%, and 86.2% of facilities accredited in the Northeast, South, Midwest, West, and Puerto Rico, respectively (P < .01, Fisher exact test). Of all echocardiographic outpatient procedures conducted (n = 1,890,156), 99.8% (n = 1,885,382) were performed in IAC-accredited echocardiographic facilities. Most procedures (90.9%) were transthoracic echocardiograms, of which 99.7% were conducted in IAC-accredited echocardiographic facilities. CONCLUSIONS: Almost all outpatient echocardiographic facilities billed by Medicare are IAC accredited. This accreditation rate is substantially higher than previously reported for US outpatient vascular testing facilities (13% IAC accredited). The uniformity of imaging and interpretation protocols from a single accrediting body is important to facilitate optimal cardiovascular care.

RESUMO

OBJECTIVES: Accreditation of cerebrovascular ultrasound laboratories by the Intersocietal Accreditation Commission (IAC) and equivalent organizations is supported by the Joint Commission certification of stroke centers. Limited information exists on the accreditation status and geographic distribution of cerebrovascular testing facilities in the United States. Our study objectives were to identify the proportion of IAC-accredited outpatient cerebrovascular testing facilities used by Medicare beneficiaries, describe their geographic distribution, and identify variations in cerebrovascular testing procedure types and volumes by accreditation status. METHODS: As part of the VALUE (Vascular Accreditation, Location, and Utilization Evaluation) Study, we examined the proportion of IAC-accredited facilities that conducted cerebrovascular testing in a 5% Centers for Medicare and Medicaid Services random Outpatient Limited Data Set in 2011 and investigated their geographic distribution using geocoding. RESULTS: Among 7327 outpatient facilities billing Medicare for cerebrovascular testing, only 22% (1640) were IAC accredited. The proportion of IAC-accredited cerebrovascular testing facilities varied by region (χ(2)[3] = 177.1; P < .0001), with 29%, 15%, 13%, and 10% located in the Northeast, South, Midwest, and West, respectively. However, of the total number of cerebrovascular outpatient procedures conducted in 2011 (38,555), 40% (15,410) were conducted in IAC-accredited facilities. Most cerebrovascular testing procedures were carotid duplex, with 40% of them conducted in IAC-accredited facilities. CONCLUSIONS: The proportion of facilities conducting outpatient cerebrovascular testing accredited by the IAC is low and varies by region. The growing number of certified stroke centers should be accompanied by more accredited outpatient vascular testing facilities, which could potentially improve the quality of stroke care.

RESUMO

BACKGROUND: The Medicare Improvements for Patients and Providers Act requires accreditation for all non-hospital suppliers of nuclear cardiology, nuclear medicine, and positron emission tomography (PET) studies as a condition of reimbursement. The perceptions of these facilities regarding the value and impact of the accreditation process are unknown. We conducted an electronic survey to assess the value of nuclear cardiology accreditation. METHODS: A request to participate in an electronic survey was sent to the medical and technical directors (n = 5,721) of all facilities who had received Intersocietal Accreditation Commission (IAC) Nuclear/PET accreditation. Demographic information, as well as, opinions on the value of accreditation as it relates to 16 quality metrics was obtained. RESULTS: There were 664 (11.6%) respondents familiar with the accreditation process of which 26% were hospital-based and 74% were nonhospital-based. Of the quality metrics examined, the process was perceived as leading to improvements by a majority of all respondents for 10 (59%) metrics including report standardization, report completeness, guideline adherence, deficiency identification, report timeliness, staff knowledge, facility distinction, deficiency correction, acquisition standardization, and image quality. Overall, the global perceived improvement was greater for hospital-based facilities (63% vs 57%; P < .001). Ninety-five percent of respondents felt that accreditation was important. Hospital-based facilities were more likely to feel that accreditation demonstrates a commitment to quality (43% vs 33%, P = .029), while nonhospital-based facilities were more likely to feel accreditation is important for reimbursement (50% vs 29%, P≤ .001). CONCLUSION: Although the accreditation process is demanding, the results of the IAC survey indicate that the accreditation process has a positive perceived impact for the majority of examined quality metrics, suggesting the facilities find the process to be valuable.

RESUMO

OBJECTIVE: There is limited information on the accreditation status and geographic distribution of vascular testing facilities in the US. The Centers for Medicare & Medicaid Services (CMS) provide reimbursement to facilities regardless of accreditation status. The aims were to: (1) identify the proportion of Intersocietal Accreditation Commission (IAC) accredited vascular testing facilities in a 5% random national sample of Medicare beneficiaries receiving outpatient vascular testing services; (2) describe the geographic distribution of these facilities. METHODS: The VALUE (Vascular Accreditation, Location & Utilization Evaluation) Study examines the proportion of IAC accredited facilities providing vascular testing procedures nationally, and the geographic distribution and utilization of these facilities. The data set containing all facilities that billed Medicare for outpatient vascular testing services in 2011 (5% CMS Outpatient Limited Data Set (LDS) file) was examined, and locations of outpatient vascular testing facilities were obtained from the 2011 CMS/Medicare Provider of Services (POS) file. RESULTS: Of 13,462 total vascular testing facilities billing Medicare for vascular testing procedures in a 5% random Outpatient LDS for the US in 2011, 13% (n=1730) of facilities were IAC accredited. The percentage of IAC accredited vascular testing facilities in the LDS file varied significantly by US region, p<0.0001: 26%, 12%, 11%, and 7% for the Northeast, South, Midwest, and Western regions, respectively. CONCLUSIONS: Findings suggest that the proportion of outpatient vascular testing facilities that are IAC accredited is low and varies by region. Increasing the number of accredited vascular testing facilities to improve test quality is a hypothesis that should be tested in future research.

RESUMO

Guilt is associated with an increased level of mood disturbance and a poorer quality of life. The aim of this study was to explore how patients with severe COPD view and experience guilt and the ways in which they cope with this guilt. A total of 31 COPD patients were interviewed about their perceptions and experiences of guilt. Qualitative content analysis was used to examine the interviews. In the descriptive (manifest) analysis, the categories "not feeling personal guilt" and "experiencing guilt" emerged; in the interpretative (latent) analysis, various strategies for dealing with guilt were identified--for example, acceptance or blaming others. Relatively few patients reported that they felt guilt on a conscious level, but those who did expressed anguish, and remorse before God; some felt blamed by others. It is important that healthcare providers acknowledge the guilt that their patients express, since guilt may have adverse effects on the patients' overall health.

RESUMO

The combined supine-prone imaging protocol for SPECT myocardial perfusion imaging offers significant advantages over supine imaging alone. By comparing supine and prone images, one can distinguish attenuation artifacts in the inferior and anterior walls from true perfusion defects, thus improving specificity and diagnostic accuracy. The recommended protocol is to perform prone imaging after supine stress imaging when perfusion defects are noted. The additional prone imaging time is 20%-40% less than the standard supine imaging time. Implementing prone imaging can optimize patient care and provide substantial benefits for nuclear cardiology labs, especially those without attenuation correction.

RESUMO

Several nuclear medicine technologist-specific groups exist on social media sites such as Facebook and LinkedIn. Although these sites provide a valuable resource and forum for technologists to interact and pose questions, any recommendations, especially those regarding patient care, should be carefully scrutinized and evaluated on the basis of scientific merit and not opinion. Recently, an assortment of unvalidated ingredients for solid-meal gastric emptying scintigraphy has been suggested on these social media sites. Often, these ingredients do not comply with the peer-reviewed guidelines and can potentially produce unreliable results and misdiagnosis. Thus, before implementing advice from an unvetted source, technologists must distinguish between low- and high-quality information. Currency, reliability, authority, and purpose-a test of the trustworthiness of an information source-can help technologists evaluate recommendations and avoid the use of unsupported solid-meal gastric emptying scintigraphy ingredients.

RESUMO

The use of medicinal cannabis has a long history dating back thousands of years. Recent discoveries have shed light on its mechanism of action with the identification of cannabinoid receptors and endocannabinoids, which make up the body's endocannabinoid system. Cannabinoid receptors, particularly the cannabinoid 1 and 2 receptors, play a crucial role in modulating the gut-brain axis and serve as potential therapeutic targets for gastrointestinal motility and inflammatory disorders. With increasing legalization of cannabis and a rising number of users, understanding the effects of cannabis on gut motility is essential for nuclear medicine providers. Although tetrahydrocannabinol, the principal psychoactive constituent of cannabis, may decrease gut motility in experimental settings, it appears to paradoxically improve symptoms in gastroparesis. Treatment effects are difficult to measure given the large number of variables that could significantly alter outcomes, such as cannabinoid type, potency, and route of intake. Another consideration is the highly personalized gut microbiome, which directly interacts with the endocannabinoid system. Further research is required to delineate these multifaceted, complex cannabinoid interactions. The goal of this article is to explore the knowns and unknowns of the impact of cannabis on the alimentary system.

RESUMO

Many variables can influence the results of gastric emptying scintigraphy (GES). A lack of standardization causes variability, limits comparisons, and decreases the credibility of the study. To increase standardization, in 2009 the Society of Nuclear Medicine and Molecular Imaging (SNMMI) published a guideline for a standardized, validated GES protocol for adults based on a 2008 consensus document. Laboratories must closely follow the consensus guideline to provide valid and standardized results as an incentive to achieve consistency in patient care. As part of the accreditation process, the Intersocietal Accreditation Commission (IAC) evaluates compliance with such guidelines. The rate of compliance with the SNMMI guideline was assessed in 2016 and showed a substantial degree of noncompliance. The aim of this study was to reassess compliance with the standardized protocol across the same cohort of laboratories, looking for changes and trends. Methods: The IAC nuclear/PET database was used to extract GES protocols from all laboratories applying for accreditation from 2018 to 2021, 5 y after the initial assessment. The number of labs was 118 (vs. 127 in the initial assessment). Each protocol was again evaluated for compliance with the methods described in the SNMMI guideline. The same 14 variables were assessed in a binary fashion: patient preparation (4 variables-types of medications withheld, withholding of these medication for 48 h, blood glucose ≤ 200 mg/dL, blood glucose recorded), meal (5 variables-use of consensus meal, nothing by mouth for 4 h or more, meal consumed within 10 min, documentation of percentage of meal consumed, meal labeled with 18.5-37 MBq [0.5-1.0 mCi]), acquisition (2 variables-anterior and posterior projections obtained, imaging each hour out to 4 h), and processing (3 variables-use of the geometric mean, decay correction of data, and measurement of percentage retention). Results: Protocols from the 118 labs demonstrated that compliance is improving in some key areas but remains suboptimal in others. Overall, labs were compliant with an average of 8 of the 14 variables, with a low of 1-variable compliance at 1 site, and only 4 sites compliant with all 14 variables. Nineteen sites met an 80% threshold for compliance (11+ variables). The variable with the highest compliance was the patient's taking nothing by mouth for 4 h or more before the exam (97%). The variable with the lowest compliance was the recording of blood glucose values (3%). Notable areas of improvement include the use of the consensus meal, now 62% versus previously only 30% of labs. Greater compliance was also noted with measurement of retention percentages (instead of emptying percentages or half-times), with compliance by 65% of sites versus only 35% 5 y prior. Conclusion: Almost 13 y after the publication of the SNMMI GES guidelines, there is improving but still suboptimal protocol adherence among laboratories applying for IAC accreditation. Persistent variation in the performance of GES protocols may significantly affect patient management, as results may be unreliable. Using the standardized GES protocol permits interpretation of results in a consistent manner that allows interlaboratory comparisons and fosters acceptance of the test validity by referring clinicians.

RESUMO

BACKGROUND: Student veterinary nurses (SVNs) complete significant time in clinical placements and this training can have a positive or negative impact on the development of professional skills and identity. METHODS: A cross-sectional design, using semi-structured interviews, explored 12 SVNs' experiences of clinical placements. Interpretative phenomenological analysis was used to explore each individual participant's experience, prior to the identification of themes across participants' experiences. RESULTS: Most students reported a sense of belonging within the practice team, which fostered engagement. Clinical supervisors were considered key role models and vital support for student progress. Students reported conflict between the demands of the practice and the requirements of their student status. Some poor interpersonal interactions led to reduced confidence. LIMITATIONS: The results may not reflect experiences of the diversity of student demographics, such as those students with protected characteristics, as described in the Equality Act 2010, who may encounter specific workplace challenges. CONCLUSION: To ensure parity and positive experiences, accredited educational institutes can plan regular engagement with student feedback and support of the training practice. Training practice teams can ensure they are meeting the student's needs and fostering a positive learning environment by adhering to the RCVS Framework for Veterinary Nurse Education and Training, which will, in turn, benefit the whole team.

RESUMO

Case studies published in the Journal of Nuclear Medicine Technology are brief chronologic or logical descriptions of a clinical experience that aim to share a technical outcome associated with an instrumentation or patient care scenario or demonstrate a unique finding associated with a nuclear medicine procedure. Although brief by necessity, case studies provide enough relevant detail to educate the reader about a clinical condition coupled with a diagnostic or therapeutic procedure. Case studies do not have to be about bizarre clinical conditions. Case studies can be about quality issues that directly impact the imaging or therapeutic procedure, protocol modifications when a clinical scenario requires out-of-the-box decisions, new techniques developed to address unique or difficult situations, or something as simple as an artifact that resulted in an unusual image finding. The sections of a case study, including the introduction, case report, discussion, and conclusion, are explained. The goal of this article is to teach new authors how to write a teaching case study.

RESUMO

Presenting an abstract at the Society of Nuclear Medicine and Molecular Imaging annual meeting is an opportunity to gain peer recognition and share knowledge. This article explains how to craft a winning conference abstract. The goal of an abstract is to summarize the main points of a research project or topic. There are 2 types of abstracts: scientific and educational. Scientific abstracts generally involve data collection or a survey and follow a specific formula. The introduction provides a brief background and states the research question. The methods describe the study design and variables. The results present key findings, and the conclusion summarizes the findings' implications and significance. Educational abstracts are unstructured and usually describe a single topic, such as a case study, literature review, or new technique. Crafting an abstract requires clear communication, attention to detail, and an emphasis on practical applications. Effectively structuring a compelling abstract increases your abstract's acceptance chances.

RESUMO

Cardiac amyloidosis is a systemic form of amyloidosis in which protein-based infiltrates are deposited in myocardial extracellular space. The accumulation of amyloid fibrils causes the myocardium to thicken and stiffen, leading to diastolic dysfunction and, eventually, heart failure. Until recently, cardiac amyloidosis was considered rare. However, the recent adoption of noninvasive diagnostic testing, including 99mTc-pyrophosphate imaging, has revealed a previously undiagnosed sizable disease prevalence. Light-chain amyloidosis (AL) and transthyretin amyloidosis (ATTR), the 2 primary types, account for 95% of cardiac amyloidosis diagnoses. AL results from plasma cell dyscrasia and has a very poor prognosis. The usual treatment for cardiac AL is chemotherapy and immunotherapy. Cardiac ATTR is more chronic, usually resulting from age-related instability and misfolding of the transthyretin protein. ATTR is treated by managing heart failure and using new pharmacotherapeutic drugs. 99mTc-pyrophosphate imaging can efficiently and effectively distinguish between ATTR and cardiac AL. Although the exact mechanism of myocardial 99mTc-pyrophosphate uptake is unknown, it is believed to bind to amyloid plaque microcalcifications. 99mTc-pyrophosphate imaging has a 97% sensitivity and nearly 100% sensitivity for identifying cardiac ATTR when the AL form of the disease is ruled out through serum free light-chain and serum and urine protein electrophoresis with immunofixation testing. Although there are no published 99mTc-pyrophosphate cardiac amyloidosis imaging guidelines, the American Society of Nuclear Cardiology, Society of Nuclear Medicine and Molecular Imaging, and others have published consensus recommendations to standardize test performance and interpretation. This article, part 1 of a 3-part series in this issue of the Journal of Nuclear Medicine Technology, describes amyloidosis etiology and cardiac amyloidosis characteristics, including the types, prevalence, signs and symptoms, and disease course. It further explains the scan acquisition protocol. Part 2 of the series focuses on image/data quantification and technical considerations. Finally, part 3 describes scan interpretation, along with the diagnosis and treatment of cardiac amyloidosis.
