RESUMO
OBJECTIVE: To identify barriers and facilitators for the access and use of primary care centers for people experiencing homelessness. DESIGN: Qualitative study, phenomenological theoretical-methodological approach. Between May 19 and July 27, 2023. LOCATION: Besòs Primary Health Care Center and Gregal social dining (Besòs and Maresme neighborhood, Barcelona). PARTICIPANTS: People experiencing homelessness attending the Gregal social dining and professionals from the Besòs Primary Health Care Center. METHOD: Theoretical purposive sampling. Individual and group interviews and open non-participant observation. Thematic content analysis, triangulation by independent analysis of three members of the research team and triangulation of methods. Discourse saturation was achieved through variability of discourse and techniques. RESULTS: Eleven individual interviews, three group interviews and two observations. Different barriers and facilitators were identified. These were classified into five categories: (1)concept and identification of people experiencing homelessness; (2)personal factors of people experiencing homelessness; (3)behaviors and attitudes of professionals; (4)structural factors related to health system regulation, anf (5)internal organizational factors of primary health care centers. CONCLUSIONS: People experiencing homelessness face multiple barriers to access primary health care, although there are also facilitators such as trusting relationships and multidisciplinary and intersectoral work that can be enhanced from primary health care centers to contribute to health equity.
RESUMO
PURPOSE: Trastuzumab improves survival in patients with HER2+ early breast cancer. However, cardiotoxicity remains a concern, particularly in the curative setting, and there are limited data on its incidence outside of clinical trials. We retrospectively evaluated the cardiotoxicity rates [left ventricular ejection fraction (LVEF) decline, congestive heart failure (CHF), cardiac death or trastuzumab discontinuation] and assessed the performance of a proposed model to predict cardiotoxicity in routine clinical practice. METHODS: Patients receiving curative trastuzumab between 2011 and 2018 were identified. Demographics, treatments, assessments and toxicities were recorded. Fisher's exact test, Chi-squared and logistic regression were used. RESULTS: 931 patients were included in the analysis. Median age was 54 years (range 24-83) and Charlson comorbidity index 0 (0-6), with 195 patients (20.9%) aged 65 or older. 228 (24.5%) were smokers. Anthracyclines were given in 608 (65.3%). Median number of trastuzumab doses was 18 (1-18). The HFA-ICOS cardiovascular risk was low in 401 patients (43.1%), medium in 454 (48.8%), high in 70 (7.5%) and very high in 6 (0.6%). Overall, 155 (16.6%) patients experienced cardiotoxicity: LVEF decline ≥ 10% in 141 (15.1%), falling below 50% in 55 (5.9%), CHF NYHA class II in 42 (4.5%) and class III-IV in 5 (0.5%) and discontinuation due to cardiac reasons in 35 (3.8%). No deaths were observed. Cardiotoxicity rates increased with HFA-ICOS score (14.0% low, 16.7% medium, 30.3% high/very high; p = 0.002). CONCLUSIONS: Cardiotoxicity was relatively common (16.6%), but symptomatic heart failure on trastuzumab was rare in our cohort. The HFA-ICOS score identifies patients at high risk of cardiotoxicity.

Long-term anti-HER2 therapy in metastatic HER2 + cancers is increasing, but data about the incidence and risk factors for developing late Cancer therapy-related cardiac dysfunction (CTRCD) are missing. We conducted a single-centre, retrospective analysis of a cohort of late anti-HER2 related cardiac dysfunction referred to our Cardio-Oncology service. We include seventeen patients with metastatic disease who developed CTRCD after at least five years of continuous anti-HER2 therapy. Events occurred after a median time of 6.5 years (IQR 5.3-9.0) on anti-HER2 therapy. The lowest (median) LVEF and GLS were 49% (IQR 45-55) and - 15.4% (IQR - 14.9 - -16.3) respectively. All our patients continued or restarted, after a brief interruption, their anti-HER2 therapy. Most (16/17) were started on heart failure medical therapy and normalized their left ventricular ejection fraction at a follow-up. Our study has demonstrated that CTRCD can occur after many years of stability on anti-HER2 therapy and reinforces the importance of continuing cardiovascular surveillance in this population.
RESUMO
Panitumumab is a human immunoglobulin monoclonal antibody designed to target the epidermal growth factor receptor (EGFR) which is used in the treatment of metastatic colorectal cancer alone or in combination with chemotherapy. In this report, we present a case of new onset heart failure with reduced ejection fraction in a patient following panitumumab therapy. A 73-year-old gentleman with metastatic rectal adenocarcinoma presented to his local hospital with increased shortness of breath, two months after his first and only dose of panitumumab. A transthoracic echocardiogram demonstrated dilated left ventricle with global hypokinesis and an estimated left ventricular ejection fraction of 25%. Our patient underwent a comprehensive diagnostic assessment at his presentation, including ECG, transthoracic echocardiogram, cardiac magnetic resonance, computed tomography coronary angiography (CTCA), invasive coronary angiogram and 18F-FDG PET-CT. These investigations revealed no evidence of ischemic events or inflammatory processes that could account for the severe left ventricular dysfunction. To our knowledge, this is the first reported case of heart failure with reduced ejection fraction linked to panitumumab with subsequent deep phenotyping. The current guidelines do not recommend specific cardiovascular monitoring protocols for patients receiving anti-EGFR monoclonal antibodies. Until more data are available, it would be prudent to implement the same cardiovascular surveillance measures outlined for individuals receiving osimertinib, which is an EGFR tyrosine kinase inhibitor.
RESUMO
BACKGROUND: The therapeutic landscape of chronic myeloid leukaemia (CML) has been transformed by tyrosine kinase inhibitors (TKI). Nilotinib, showed higher rates of major molecular response than imatinib, however associated with higher cardiovascular (CV) toxicity. We sought to describe the CV events associated with nilotinib in a real-world population and assess the predictive value of the HFA-ICOS risk score. METHODS: The HFA-ICOS baseline risk was calculated for patients with CML treated with nilotinib beween 2006 and 2021. The primary end point was the incidence of all CV events. The secondary end point was the incidence of ischaemic events. Survival analysis evaluated the risk (hazard ratio [HR]) of events stratified by baseline risk category, whilst on nilotinib therapy. RESULTS: Two hundred and twenty-nine eligible patients were included. The incidence of CV events was 20.9% (95% CI: 15.7-26.2%) following a median duration of treatment of 34.4 months. The secondary end point occurred in 12.7% (95% CI: 8.4-16.9%) of the population. Patients with higher HFA-ICOS baseline score had higher rates of CV events (low: 11.2%, medium: 28.2% [HR: 2.51, 95% CI: 1.17-5.66], high/very high: 32.4% [HR: 3.57, 95% CI: 1.77-7.20]) and ischaemic events (low: 5.20%, medium: 17.9% [HR: 2.19, 95% CI: 0.97-4.96], high/very high: 21.6% [HR: 3.9, 95% CI: 1.91-7.89]). In patients who did not have a CV event, the median total dose at last follow up or cessation of nilotinib therapy was lower when compared to the total daily median dose of nilotinib in patients who had a CV event (450 mg vs. 600 mg, p = 0.0074). CONCLUSIONS: The HFA-ICOS risk stratification tool is an efficient discriminator at low, medium and high/very high risk of developing cardiovascular events, with an overall positive trend towards increasing cardiotoxicity rates with rising risk catergories. This study provides evidence to support the use of this predictive tool in nilotinib treated patients.
RESUMO
Purpose To compare left ventricular ejection fraction (LVEF) measured with echocardiography and cardiac MRI in individuals with cancer and suspected cardiotoxicity and assess the potential effect on downstream clinical decision-making. Materials and Methods In this prospective, single-center observational cohort study, participants underwent same-day two-dimensional (2D) echocardiography and cardiac MRI between 2011 and 2021. Participants with suboptimal image quality were excluded. A subset of 74 participants also underwent three-dimensional (3D) echocardiography. The agreement of LVEF derived from each modality was assessed using Bland-Altman analysis and at relevant thresholds for cardiotoxicity. Results A total of 745 participants (mean age, 60 years ± 5 [SD]; 460 [61.7%] female participants) underwent same-day echocardiography and cardiac MRI. According to Bland-Altman analysis, the mean bias was -3.7% ± 7.6 (95% limits of agreement [LOA]: -18.5% to 11.1%) for 2D echocardiography versus cardiac MRI. In 74 participants who underwent cardiac MRI, 3D echocardiography, and 2D echocardiography, the mean LVEFs were 60.0% ± 10.4, 58.4% ± 9.4, and 57.2% ± 8.9, respectively (P < .001). At the 50% LVEF threshold for detection of cardiotoxicity, there was disagreement for 9.3% of participants with 2D echocardiography and cardiac MRI. Agreement was better with 3D echocardiography and cardiac MRI (mean bias, -1.6% ± 6.3 [95% LOA: -13.9% to 10.7%]) compared with 2D echocardiography and cardiac MRI (mean bias, -2.8% ± 6.3 [95% LOA: -15.2% to 9.6%]; P = .016). Conclusion Two-dimensional echocardiography had variations of ±15% for LVEF measurement compared with cardiac MRI in participants with cancer and led to misclassification of approximately 10% of participants for cardiotoxicity detection. Three-dimensional echocardiography had better agreement with cardiac MRI and should be used as first-line imaging.

The advent of immunological therapies has revolutionized the treatment of solid and haematological cancers over the last decade. Licensed therapies which activate the immune system to target cancer cells can be broadly divided into two classes. The first class are antibodies that inhibit immune checkpoint signalling, known as immune checkpoint inhibitors (ICIs). The second class are cell-based immune therapies including chimeric antigen receptor T lymphocyte (CAR-T) cell therapies, natural killer (NK) cell therapies, and tumour infiltrating lymphocyte (TIL) therapies. The clinical efficacy of all these treatments generally outweighs the risks, but there is a high rate of immune-related adverse events (irAEs), which are often unpredictable in timing with clinical sequalae ranging from mild (e.g. rash) to severe or even fatal (e.g. myocarditis, cytokine release syndrome) and reversible to permanent (e.g. endocrinopathies).The mechanisms underpinning irAE pathology vary across different irAE complications and syndromes, reflecting the broad clinical phenotypes observed and the variability of different individual immune responses, and are poorly understood overall. Immune-related cardiovascular toxicities have emerged, and our understanding has evolved from focussing initially on rare but fatal ICI-related myocarditis with cardiogenic shock to more common complications including less severe ICI-related myocarditis, pericarditis, arrhythmias, including conduction system disease and heart block, non-inflammatory heart failure, takotsubo syndrome and coronary artery disease. In this scientific statement on the cardiovascular toxicities of immune therapies for cancer, we summarize the pathophysiology, epidemiology, diagnosis, and management of ICI, CAR-T, NK, and TIL therapies. We also highlight gaps in the literature and where future research should focus.
RESUMO
There is growing interest in the role of coronary computed tomography angiography (CTA) in cardio-oncology. However, there is a paucity of real-world experience and outcome data for patients with cancer. This study sought to determine the clinical utility and prognostic value of coronary CTA in patients with cancer. In this prospective, single-center study, we recruited patients with cancer who underwent coronary CTA. Coronary artery disease (CAD) extent was classified as normal, nonobstructive (1% to 49% stenosis), and potentially obstructive (≥50% stenosis). Patients were followed up for a median of 9 months (interquartile range 3 to 30 months) for cancer-related deaths and major adverse cardiovascular events (MACEs) defined as nonfatal myocardial infarction, urgent unplanned revascularization, or cardiovascular death. The mean age of patients (n = 113) was 61 ± 12 years, and 68 were female (60%). The most common underlying cancers were breast (29%) and lymphoma (13%). A total of 25 patients had potentially obstructive CAD, most commonly of the left anterior descending artery. After coronary CTA, 88% statin-naive patients with potentially obstructive CAD were initiated on statin therapy. A total of 28/32 patients who were taking fluoropyrimidine chemotherapy (5-fluorouracil or capecitabine) continued therapy, of whom none had MACEs. Overall, there were no episodes of MACEs in this cohort and 11% had cancer-related deaths. Coronary CTA has an important role in the clinical decision-making in patients with cancer to detect CAD, initiate primary preventative therapy, and guide coronary revascularization. No MACEs occurred. Using this coronary CTA-guided approach, preventative therapy was initiated, and most patients continued prognostically important cancer therapy.

BACKGROUND: The full range of cardiovascular complications related to the use of Immune checkpoint inhibitors (ICI) is not fully understood. We aim to describe the spectrum of cardiovascular adverse events (cvAEs) by presenting our real-world experience of the diagnosis and management of these complications. METHODS: Two thousand six hundred and forty-seven (2647) patients were started on ICI treatment between 2014 and 2020. Data from 110 patients referred to the cardio-oncology service with a suspected cvAE was collected prospectively and analysed. RESULTS: Eighty-nine patients (3.4%) were confirmed to have cvAEs while on ICI therapy. Myocarditis was the most frequent event (33/89), followed by tachyarrhythmia (27/89), non-inflammatory left ventricular dysfunction (NILVD) (15/89) and pericarditis (7/89). Results from myocarditis and non-inflammatory left ventricular dysfunction cohorts were compared. Myocarditis and NILVD showed significant differences in respect toof troponin elevation, cardiac magnetic resonance abnormalities and ventricular function. Dual ICI therapy and other immune related adverse events were more frequently associated with myocarditis than NILVD. There was a significant difference in the median time from starting ICI treatment to presentation with myocarditis versus NILVD (12 vs 26 weeks p = 0.049). Through early recognition of myocarditis, prompt treatment with steroids and interruption of ICI, there were no cardiovascular in-hospital deaths. NILVD did not require steroid treatment and ICI could be restarted safely. CONCLUSIONS: The full spectrum of cardiovascular complications in patients with immune checkpoint inhibitors is much broader than initially described. Myocarditis remains the most frequent cvAE related to ICI treatment. A novel type of myocardial injury was observed and defined as Atrial tachyarrhythmias and NILVD were also frequent in this cohort. NILVD has a This differs fromdifferent presentation from ICI-related myocarditis, mainly usually presenting afterby the lack of inflammatory features on CMR and biomarkers and a later presentation in time.
RESUMO
Introducción El implante valvular aórtico percutáneo es una opción terapéutica cada vez más utilizada en pacientes en los que se descarta la cirugía. A pesar de que las alteraciones agudas de la conducción son una de las complicaciones más frecuentes, su significado clínico y electrocardiográfico no es del todo claro. Objetivos Determinar las implicaciones pronósticas del desarrollo de alteraciones agudas de la conducción luego del implante valvular aórtico percutáneo. Resultados Entre marzo de 2009 y febrero de 2012 se incluyeron para el análisis 47 pacientes; de ellos, 30 (63%) presentaron alteraciones agudas de la conducción: 19 pacientes solo bloqueo completo de rama izquierda (BCRI), 9 pacientes solo bloqueo auriculoventricular completo (BAVC) y 2 pacientes presentaron ambos trastornos, los que totalizaron 21 BCRI y 11 BAVC. A 12 (25%) se les implantó un marcapasos definitivo previo al alta: en 11 por BAVC y en 1 por BCRI agudo más fibrilación auricular. En solo un paciente el BAVC revirtió en hemodinamia. Los pacientes que persistieron con BAVC posintervención presentaron una media de estimulación ventricular en la intervalometría al mes del 90%, mientras que en el paciente con BAVC que revirtió en hemodinamia fue de solo el 3% y en el paciente con BCRI más fibrilación auricular fue < 10%. La incidencia de insuficiencia cardíaca en el posoperatorio fue mayor en los pacientes con alteraciones agudas de la conducción (p = 0,007), al igual que la estadía hospitalaria (p = 0,045). En el seguimiento no hubo diferencias en la tasa de reinternación ni en la mortalidad. Conclusiones En el presente estudio el desarrollo de alteraciones agudas de la conducción mostró un aumento en la incidencia de insuficiencia cardíaca y en los días de internación, sin incremento en la tasa de otros eventos mayores. La colocación de un marcapasos definitivo luego del BAVC podría realizarse en forma inmediata, ya que el trastorno generalmente es irreversible.
Introduction The indication of transcatheter aortic valve implantation in patients considered not suitable candidates for surgery is increasing. Despite acute disorders of the conduction system are common complications, their clinical and electrocardiographic significance is not completely clear. Objectives To determine whether acute disorders of the conduction system after transcatheter aortic valve implantation has prognostic implications. Results Between March 2009 and February 2012, 47 patients were included in the analysis. Thirty patients (63%) had acute disorders of the conduction system: 19 patients presented isolated complete left bundle branch block (LBBB), 9 patients isolated complete atrioventricular block (CAVB), and 2 patients both conduction disorders, with a total of 21 LBBBs and 11 CAVBs. A definite pacemaker was implanted in 12 patients (25%) before discharge: in 11 due to CAVB and in 1 due to acute LBBB plus atrial fibrillation. Complete AVB reverted in the catheterization laboratory in only one patient. At one month, average ventricular pacing was 90% in patients with persistent CAVB after the intervention, only 3% in the only patient in whom CAVB reverted at the catheterization laboratory and < 10% in the patient with LBB plus atrial fibrillation. The incidence of postoperative heart failure and hospital stay was greater in patients with acute disorders of the conduction system (p = 0.007 and p = 0.045, respectively). There were no differences in new hospitalizations and mortality during follow-up. Conclusions In this study, the development of acute disorders of the conduction system was associated with increased incidence of heart failure and hospital stay but not with the incidence of major events. A definite pacemaker could be implanted immediately after CAVB develops as the conduction disorder is generally irreversible.
