RESUMO
While allograft rejection (AR) continues to threaten the success of cardiothoracic transplantation, lack of accurate and repeatable surveillance tools to diagnose AR is a major unmet need in the clinical management of cardiothoracic transplant recipients. Endomyocardial biopsy (EMB) and transbronchial biopsy (TBBx) have been the cornerstone of rejection monitoring since the field's incipience, but both suffer from significant limitations, including poor concordance of biopsy interpretation among pathologists. In recent years, novel molecular tools for AR monitoring have emerged and their performance characteristics have been evaluated in multiple studies. An international working group convened by ESOT has reviewed the existing literature and provides a series of recommendations to guide the use of these biomarkers in clinical practice. While acknowledging some caveats, the group recognized that Gene-expression profiling and donor-derived cell-free DNA (dd-cfDNA) may be used to rule out rejection in heart transplant recipients, but they are not recommended for cardiac allograft vasculopathy screening. Other traditional biomarkers (NT-proBNP, BNP or troponin) do not have sufficient evidence to support their use to diagnose AR. Regarding lung transplant, dd-cfDNA could be used to rule out clinical rejection and infection, but its use to monitor treatment response is not recommended.

INTRODUCTION: The ACHOCC-19 study was performed to characterize COVID-19 infection in a Colombian oncological population. METHODOLOGY: Analytical cohort study of patients with cancer and COVID-19 infection in Colombia. From April 1 to October 31, 2020. Demographic and clinical variables related to cancer and COVID-19 infection were collected. The primary outcome was 30-day mortality from all causes. The association between the outcome and the prognostic variables was analyzed using logistic regression models and survival analysis with Cox regression. RESULTS: The study included 742 patients; 72% were >51 years. The most prevalent neoplasms were breast (132, 17.77%), colorectal (92, 12.34%), and prostate (81, 10.9%). Two hundred twenty (29.6%) patients were asymptomatic and 96 (26.3%) died. In the bivariate descriptive analysis, higher mortality occurred in patients who were >70 years, patients with lung cancer, ≥2 comorbidities, former smokers, receiving antibiotics, corticosteroids, and anticoagulants, residents of rural areas, low socioeconomic status, and increased acute-phase reactants. In the logistic regression analysis, higher mortality was associated with Eastern Cooperative Oncology Group performance status (ECOG PS) 3 (odds ratio [OR] 28.67; 95% confidence interval [CI], 8.2-99.6); ECOG PS 4 (OR 20.89; 95% CI, 3.36-129.7); two complications from COVID-19 (OR 5.3; 95% CI, 1.50-18.1); and cancer in progression (OR 2.08; 95% CI, 1.01-4.27). In the Cox regression analysis, the statistically significant hazard ratios (HR) were metastatic disease (HR 1.58; 95% CI, 1.16-2.16), cancer in progression (HR 1.08; 95% CI, 1.24-2.61) cancer in partial response (HR 0.31; 95% CI, 0.11-0.88), use of steroids (HR 1.44; 95% CI, 1.01-2.06), and use of antibiotics (HR 2.11; 95% CI, 1.47-2.95). CONCLUSION: In our study, patients with cancer have higher mortality due to COVID-19 infection if they have active cancer, metastatic or progressive cancer, ECOG PS >2, and low socioeconomic status. IMPLICATIONS FOR PRACTICE: This study's findings raise the need to carefully evaluate patients with metastatic cancer, in progression, and with impaired Eastern Cooperative Oncology Group status to define the relevance of cancer treatment during the pandemic, consider the risk/benefit of the interventions, and establish clear and complete communication with the patients and their families about the risk of complications. There is also the importance of offering additional support to patients with low income and residence in rural areas so that they can have more support during cancer treatment.

BACKGROUND: Hyponatraemia is common in patients with acute heart failure (HF). AIMS: To determine the impact of sodium disturbances on mortality and readmissions in HF with reduced left ventricular ejection fraction (HFrEF), preserved ejection fraction (HFpEF) and mid-range ejection fraction (HFmrEF). METHODS: This study was a prospective multicentre consecutive registry in 20 hospitals, including patients admitted due to acute HF in cardiology departments. Sodium <135 mmol/L was considered hyponatraemia, >145 mmol/L hypernatraemia and 135-145 mmol/L normal. RESULTS: A total of 1309 patients was included. Mean age was 72.0 ± 11.9 years, and 810 (61.9%) were male. Mean serum sodium level was 138.6 ± 4.7 mmol/L at hospital admission and 138.1 ± 4.1 mmol/L at discharge. The evolution of sodium levels was: normal-at-admission/normal-at-discharge 941 (71.9%), abnormal-at-admission/normal-at-discharge 127 (9.7%), normal-at-admission/abnormal-at-discharge 155 (11.8%) and abnormal-at-admission/abnormal-at-discharge 86 (6.6%). Hyponatraemia at discharge was more common in HFrEF (109 (20.7%)) than in HFpEF (79 (13.9%)) and HFmrEF (27 (12%)), P = 0.003. The prevalence of hypernatraemia at discharge was similar in the three groups: HFrEF (10 (1.9%)), HFpEF (12 (2.1%)) and HFmrEF (4 (1.9%)), P = 0.96. In multivariate analysis, abnormal sodium concentrations at hospital admission (hazard ratio (HR) 1.42, 95% confidence interval (CI) 1.15-1.76, P = 0.001) and discharge (HR 1.33, 95% CI 1.08-1.64, P = 0.007) were both independently associated with increased mortality and readmissions at 12 months. CONCLUSIONS: Hyponatraemia and hypernatraemia at admission and discharge predict a poor outcome in patients with acute HF regardless of left ventricular ejection fraction. Hyponatraemia at discharge is more frequent in HFrEF than in the other groups.

BACKGROUND: Medical therapy could improve the prognosis of real-life patients discharged after a heart failure (HF) hospitalisation. AIM: To determine the impact of discharge HF treatment on mortality and readmissions in different left ventricular ejection fraction (LVEF) groups. METHODS: Multicentre prospective registry in 20 Spanish hospitals. Patients were enrolled after a HF hospitalisation. RESULTS: A total of 1831 patients was included (583 (31.8%) HF with reduced ejection fraction (HFrEF); 227 (12.4%) HF with midrange ejection fraction (HFmrEF); 610 (33.3%) HF with preserved ejection fraction (HFpEF), and 411 (22.4%) with unknown LVEF). Angiotensin-converting enzyme (ACE) inhibitors/angiotensin II receptor blockers (ARB) at discharge were independently associated with a reduction in: (i) all-cause mortality: hazard ratio (HR) 0.55, 95% confidence interval (CI) 0.41-0.74, P < 0.001, with a similar effect in the four groups; (ii) mortality due to refractory HF HR 0.45, 95% CI 0.29-0.64, P < 0.001, with a similar effect in the three groups with known LVEF; (iii) mortality/HF admissions (HR 0.61; 95% CI: 0.50-0.74), more evident in HFrEF (HR 0.54; 95% CI: 0.38-0.78) compared with HRmEF (HR 0.64; 95% CI 0.40-1.02), or HFpEF (HR 0.70; 95% CI 0.53-0.92). In patients with HFrEF triple therapy (ACE inhibitor/ARB + beta blocker + mineralocorticoid receptor antagonist) was associated with the lowest mortality risk (HR 0.21; 95% CI: 0.08-0.57, P = 0.002) compared with patients that received none of these drugs. CONCLUSIONS: Discharge treatment with ACE inhibitor/ARB after a HF hospitalisation is associated with a reduction in all-cause and refractory HF mortality, irrespective of LVEF.

Aims: Techniques for identifying specific microcirculatory structural changes are desirable. As such, capillary rarefaction constitutes one of the earliest changes of cardiac allograft vasculopathy (CAV) in cardiac allograft recipients, but its identification with coronary flow reserve (CFR) or intracoronary resistance measurements is hampered because of non-selective interrogation of the capillary bed. We therefore investigated the potential of wave intensity analysis (WIA) to assess capillary rarefaction and thereby predict CAV. Methods and results: Fifty-two allograft patients with unobstructed coronary arteries and normal left ventricular (LV) function were assessed. Adequate aortic pressure and left anterior descending artery flow measurements at rest and with intracoronary adenosine were obtained in 46 of which 2 were lost to follow-up. In a subgroup of 15 patients, simultaneous RV biopsies were obtained and analysed for capillary density. Patients were followed up with 1-3 yearly screening angiography. A significant relationship with capillary density was noted with CFR (r = 0.52, P = 0.048) and the backward decompression wave (BDW) (r = -0.65, P < 0.01). Over a mean follow-up of 9.3 ± 5.2 years patients with a smaller BDW had an increased risk of developing angiographic CAV (hazard ratio 2.89, 95% CI 1.12-7.39; P = 0.03). Additionally, the index BDW was lower in those who went on to have a clinical CAV-events (P = 0.04) as well as more severe disease (P = 0.01). Conclusions: Within cardiac transplant patients, WIA is able to quantify the earliest histological changes of CAV and can predict clinical and angiographic outcomes. This proof-of-concept for WIA also lends weight to its use in the assessment of other disease processes in which capillary rarefaction is involved.

The results of studies on the association between sex mismatch and survival after heart transplantation are conflicting. Data from the Spanish Heart Transplantation Registry. From 4625 recipients, 3707 (80%) were men. The donor was female in 943 male recipients (25%) and male in 481 female recipients (52%). Recipients of male hearts had a higher body mass index (25.9 ± 4.1 vs. 24.3 ± 3.7; P < 0.01), and male donors were younger than female donors (33.4 ± 12.7 vs. 38.2 ± 12.3; P < 0.01). No further relevant differences related to donor sex were detected. In the univariate analysis, mismatch was associated with mortality in men (hazard ratio [HR], 1.18; 95% confidence interval [CI], 1.06-1.32; P = 0.003) but not in women (HR, 0.91; 95% CI 0.74-1.12; P = 0.4). A significant interaction was detected between sex mismatch and recipient gender (P = 0.02). In the multivariate analysis, sex mismatch was associated with long-term mortality (HR, 1.14; 95% CI 1.01-1.29; P = 0.04), and there was a tendency toward significance for the interaction between sex mismatch and recipient gender (P = 0.08). In male recipients, mismatch increased mortality mainly during the first month and in patients with pulmonary gradient >13 mmHg. Sex mismatch seems to be associated with mortality after heart transplantation in men but not in women.

INTRODUCTION: Hispanics report higher rates of problematic alcohol use compared to non-Hispanic Whites while also reporting lower rates of alcohol treatment utilization compared to non-Hispanics. The study employs Anderson's Behavioral Model of Healthcare Utilization Model to guide the exploration of alcohol use, help-seeking and healthcare utilization. METHODS: The present qualitative study explored help-seeking and alcohol treatment utilization for Hispanic men of Mexican ethnicity. A total of 27 participants (Mage = 35.7, SD = 10.82) completed a semi-structured interview that explored the treatment experiences and underlying psychological mechanisms that shaped their help-seeking. RESULTS: Through a thematic content analysis, the following themes emerged: 1) perceiving need with subthemes of familismo, role as protector and provider, and positive face; 2) predisposing beliefs on help-seeking; and 3) treatment experiences and elements of patient satisfaction with subthemes of monetized treatment, respect, and perceiving professional stigma. CONCLUSIONS: The findings in this article may assist in improving strategies for increasing alcohol treatment utilization among men of Mexican ethnicity. By exploring beliefs, values, and experiences health researchers can develop culturally informed intervention strategies.

We sought to determine the incidence, risk factors, and consequences of acute rejection (AR) after conversion from a calcineurin inhibitor (CNI) to a proliferation signal inhibitor (PSI) in maintenance heart transplantation. Relevant clinical data were retrospectively obtained for 284 long-term heart transplant recipients from nine centers in whom CNIs were replaced with a PSI (sirolimus or everolimus) between October 2001 and March 2009. The rejection rate at one yr was 8.3%, stabilizing to 2% per year thereafter. The incidence rate after conversion (4.9 per 100 patient-years) was significantly higher than that observed on CNI therapy in the pre-conversion period (2.2 per 100 patient-years). By multivariate analysis, rejection risk was associated with a history of late AR prior to PSI conversion, early conversion (<5 yr) after transplantation and age <50 yr at the time of conversion. Use of mycophenolate mofetil was a protective factor. Post-conversion rejection did not significantly influence the evolution of left ventricular ejection fraction, renal function, or mortality during further follow-up. Conversion to a CNI-free immunosuppression based on a PSI results in an increased risk of AR. Awareness of the clinical determinants of post-conversion rejection could help to refine the current PSI conversion strategies.

AIMS: Mitochondrial haplogroups are known to influence individual predisposition to a wide spectrum of metabolic and degenerative diseases, including ischaemic cardiovascular diseases. We have examined the influence of the mitochondrial DNA (mtDNA) background on the development of human end-stage heart failure (HF) in patients undergoing heart transplantation. The influence of mtDNA haplogroups on the incidence of transplant-related complications, mainly cardiac allograft vasculopathy (CAV), and on post-transplant survival was also studied. METHODS AND RESULTS: The most common mitochondrial haplogroups in European populations were genotyped in 450 heart transplant recipients, 248 heart transplant donors, and 206 healthy controls. Mitochondrial haplogroups were determined by PCR amplification of short mtDNA fragments, followed by restriction fragment length polymorphism analysis. After adjustment for age and sex the frequency of haplogroup H was significantly higher in heart transplant recipients than in controls [OR: 1.86 (95% confidence intervals, CI: 1.27-2.74), P= 0.014], and in heart donors [OR: 1.47 (95% CI: 0.99-2.19), P= 0.032]. Likewise, haplogroup Uk was found significantly more frequently among CAV patients than in non-CAV heart allograft recipients [OR: 4.1 (95% CI: 1.51-11.42), P= 0.042]. Finally, heart donor haplogroups had no influence on the morbidity or mortality after heart transplantation. CONCLUSIONS: Mitochondrial haplogroups behave like risk factors for the progress to end-stage HF in a Spanish cardiac transplant population. Mitochondrial DNA variants may have some influence on the appearance of cardiac transplant complications.

INTRODUCTION: hip fracture represents a global health problem, with a high morbidity and mortality rate and an increasing incidence. The treatment of trochanteric fractures is reduction and osteosynthesis, and implant selection depends mainly on the stability of the fracture and lateral wall competence. Lateral wall competence has gained relevance in recent years, which led to the modification of the AO/OTA classification. However, determination of lateral wall integrity is difficult from plain radiographs; the influence of images with traction on its measurement has not been evaluated. METHODS: prospective concordance study, emergency and post-traction radiographs of 65 patients with trochanteric fracture were evaluated by six orthopedic surgeons independently, measuring the lateral wall, classifying the fracture according to the AO/OTA 2018 classification and selecting the implant for osteosynthesis. A comparison of incompetent to intact lateral wall proportion between each image set was made. Secondary outcomes were the inter-observer correlation of lateral wall measurement and inter-observer agreement of classification and implant choice. RESULTS: the proportion of patients with an incompetent lateral wall in emergency x-ray was 37.43% (CI 95% 0.326-0.422), while the proportion in post-traction fluoroscopy was 15% (CI 95% 0.115-0.185), with a statistically significant difference (p < 0.001). 40.1% of patients with an incompetent lateral wall changed to an intact one. Inter-observer correlation for the lateral wall thickness was 0.399 (CI 95% 0.292-0.519) in emergency x-ray and 0.658 (CI 95% 0.564-0.748) in post-traction fluoroscopy, with a substantial agreement. Inter-observer agreement for the fracture classification was fair to moderate using emergency x-ray (κ 0.369 95%CI 0.330-0.408) and fair to moderate with post-traction fluoroscopy (κ 0.400, 95% CI 0.334-0.466). CONCLUSION: traction images significantly change the measurement of the lateral wall in trochanteric fractures, changing from an incompetent to a competent wall in 40% of patients. The correct classification of trochanteric fractures is crucial to make the best decision when deciding which implant to use, and the measurement of the lateral wall is determinant in the actual AO/OTA classification. Therefore, traction images appear as necessary for correct decision-making.

Our aim was to determine the prognostic impact of coronary artery disease (CAD) on heart failure with reduced ejection fraction (HFrEF) mortality and readmissions. From a prospective multicenter registry that included 1831 patients hospitalized due to heart failure, 583 had a left ventricular ejection fraction of <40%. In total, 266 patients (45.6%) had coronary artery disease as main etiology and 137 (23.5%) had idiopathic dilated cardiomyopathy (DCM), and they are the focus of this study. Significant differences were found in Charlson index (CAD 4.4 ± 2.8, idiopathic DCM 2.9 ± 2.4, p < 0.001), and in the number of previous hospitalizations (1.1 ± 1, 0.8 ± 1.2, respectively, p = 0.015). One-year mortality was similar in the two groups: idiopathic DCM (hazard ratio [HR] = 1), CAD (HR 1.50; 95% CI 0.83-2.70, p = 0.182). Mortality/readmissions were also comparable: CAD (HR 0.96; 95% CI 0.64-1.41, p = 0.81). Patients with idiopathic DCM had a higher probability of receiving a heart transplant than those with CAD (HR 4.6; 95% CI 1.4-13.4, p = 0.012). The prognosis of HFrEF is similar in patients with CAD etiology and in those with idiopathic DCM. Patients with idiopathic DCM were more prone to receive heart transplant.
RESUMO
In Colombia, renal cancer is a rare condition, with clear cell renal cell carcinoma (ccRCC) being the most prevalent neoplasm. In recent years, immune checkpoint inhibitors (ICI) have been proposed for the management of metastatic disease, as they have shown improved rates of response and long-term survival. Furthermore, they exhibit a favourable tolerance profile, and adverse events causing significant morbidity are infrequent. We report the case of a 61-year-old male patient initially diagnosed with early-stage ccRCC who underwent right nephrectomy in 2009. Six years later, disease recurrence with metastatic compromise was documented, which led to the resection of the L1 vertebral body followed by radiotherapy and maintenance treatment with sunitinib. Due to disease progression, treatment with sunitinib was discontinued. Subsequently, everolimus was initiated as second-line immunotherapy, which was later discontinued due to the appearance of new metastatic lesions. In 2017, the patient was referred to our institution, where a third-line pharmacological treatment with nivolumab was initiated. In 2022, complete remission by positron emission tomography-computed tomography (PET-CT) was evidenced, which has been sustained to date. This case demonstrates the efficacy and safety of ICI in patients with metastatic ccRCC. The case presented is relevant in that it describes the achievement of complete remission in a patient who did not respond to the first two lines of immunotherapy. Given the limited literature regarding the discontinuation of therapy after achieving sustained remission, further research is warranted to explore this topic.
RESUMO
Background: Cardiorenal programs have emerged to improve the management of cardiorenal disease (CRD). Evidence about the benefits of these programs is still scarce. This work aims to evaluate the performance of a novel cardiorenal program and describe the clinical profile and outcomes of patients with CRD. Methods: We conducted a retrospective observational study of patients with CRD attended in a cardiorenal unit (CRU) from February 2021 to February 2022. Demographics and laboratory tests were collected and events (all-cause death and cardiovascular hospitalizations) were evaluated. Optimization of comorbidities and protective therapies was also assessed. Results: Eighty-two patients were included, with a mean age of 76.8 years [standard deviation (SD) 8.5] and 72% were men. A total of 58.5% (n = 47) had left ventricular ejection fraction <50%. The mean follow-up was 11 months (SD 4.0). Almost 54% of the patients (n = 44) required hospitalization, 30.5% for heart failure (HF) decompensation. Total hospitalizations significantly decreased after CRU inclusion: 0.70 versus 0.45 admissions/year (P < .02). Global mortality was 17.1% (n = 14). The percentage of patients with HF with reduced ejection fraction on quadruple therapy increased by 20%, and up to 60% of the patients were on three drugs. A total of 39% of the patients with HF and preserved ejection fraction started treatment with sodium-glucose co-transporter inhibitors. Hyperkalaemia required the use of potassium binders in 12.2% of the patients and treatment of secondary hyperparathyroidism was started in 42.7% and renal anaemia in 23.2%. Renal replacement therapy was initiated in 10% of the patients (n = 8). Conclusion: CRD confers a considerable risk of adverse outcomes. Cardiorenal programs may improve cardiorenal syndrome management by optimizing therapies, treating comorbidities and reducing hospitalizations.
RESUMO
OBJECTIVE: We sought to investigate prevalence, incidence and prognostic implications of permanent pacemaker (PPM) implantation in patients with cardiac amyloidosis (CA), thereby identifying the predictors of time to PPM implantation. METHODS: Seven hundred eighty-seven patients with CA (602 men, median age 74 years, 571 transthyretin amyloidosis (ATTR), 216 light-chain amyloidosis (AL)) evaluated at two European referral centres were retrospectively included. Clinical, laboratory and instrumental data were analysed. The associations between PPM implantation and mortality, heart failure (HF) or a composite endpoint of mortality, cardiac transplantation and HF were analysed. RESULTS: 81 (10.3%) patients had a PPM before initial evaluation. Over a median follow-up time of 21.7 months (IQR 9.6-45.2), 81 (10.3%) additional patients (18 with AL (22.2%) and 63 with ATTR (77.8%)) underwent PPM implantation with a median time to implantation of 15.6 months (IQR 4.2-40), complete atrioventricular block was the most common indication (49.4%). Independent predictors of PPM implantation were QRS duration (HR 1.03, 95% CI 1.02 to 1.03, p<0.001) and interventricular septum (IVS) thickness (HR 1.1, 95% CI 1.03 to 1.17, p=0.003). The model to estimate the probability of PPM at 12 months and containing both factors showed a C-statistic of 0.71 and a calibration of slope of 0.98. CONCLUSIONS: Conduction system disease requiring PPM is a common complication in CA that affects up to 20.6% of patients. QRS duration and IVS thickness are independently associated with PPM implantation. A PPM implantation at 12 months model was devised and validated to identify patients with CA at higher risk of requiring a PPM and who require closer follow-up.

A pulmonary hypertension (PH) registry (Spanish Registry of Pulmonary Arterial Hypertension) was undertaken to analyse prevalence, incidence and survival of pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH) in Spain, and to assess the applicability of recent survival prediction equations. Voluntary reporting of previously diagnosed and incident PAH or CTEPH cases (July 2007-June 2008) was performed. Demographic, functional and haemodynamic variables were evaluated. 866 patients with PAH and 162 with CTEPH were included. PAH associated with toxic oil syndrome and pulmonary veno-occlusive disease were reported for the first time in a PAH registry. Estimated prevalences were as follows: PAH, 16 and CTEPH, 3.2 cases per million adult inhabitants (MAI). Estimated incidences were as follows: PAH, 3.7 and CTEPH, 0.9 cases per MAI per yr. 1-, 3- and 5-yr survival was 87%, 75% and 65%, respectively, with no differences between PAH and CTEPH. Male sex, right atrial pressure and cardiac index were independent predictors of death. Matching between observed survival and that predicted by different equations was closer when the characteristics of the cohorts were similar. Epidemiology and survival of PAH patients in the Spanish registry are similar to recent registries. Characteristics of the population from which survival prediction equations are derived influence their applicability to a different cohort. CTEPH is much less prevalent than PAH, although has a similar survival rate.

BACKGROUND: Congenital heart diseases (CHDs) have high infant mortality in their severe forms. When adulthood is reached, a heart transplant (HTx) may be required. Spanish adult population transplanted for CHD was analyzed and compared with the most frequent causes of HTx and between different subgroups of CHD. MATERIALS AND METHODS: A total of 6048 patients (HTx 1984-2009) were included. Pediatric transplants (<15 yr), combined transplants, reHTx, and HTx for heart diseases other than idiopathic dilated cardiomyopathy (IDCM) and ischemic heart disease (IHD) were excluded. Total patients included: 3166 (IHD = 1888; IDCM = 1223; CHD = 55). Subgroups were studied as follows: (1) single ventricle with pulmonary stenosis (n = 18), (2) single ventricle with tricuspid atresia and Glenn/Fontan surgery (n = 10), (3) congenitally corrected transposition of the great vessels (TGV) or with switch atrial surgery (n = 10), and (4) CHD with right ventricle overload (n = 17). RESULTS: Survival probability was different between groups (p = 0.0001). Post hoc analysis showed some differences between groups (CHD vs. IHD, p = 0.05; CHD vs. IDCM, p = 0.5; IHD vs. IDCM, p = 0.0001). Early mortality was different between CHD subgroups (group 1 = 19%, group 2 = 40%, group 3 = 0%, group 4 = 29%; p < 0.001); however, overall mortality did not show differences between subgroups (p = 0.5). CONCLUSIONS: The percentage of Spanish adult HTx patients for CHD is low (1%). The survival curve is better than for other HTx causes (IHD). Nevertheless, early mortality was higher, particularly in some subgroups (Fontan).

AIMS: Transthyretin amyloid cardiomyopathy (ATTR-CM) is increasingly recognized as a cause of heart failure in the elderly. Although wild-type transthyretin amyloidosis is the most frequent form of ATTR-CM found in the elderly, hereditary transthyretin amyloidosis (ATTRv) can also occur. We sought to determine the prevalence of ATTRv among elderly ATTR-CM patients, identify predictors of ATTRv and evaluate the clinical consequences of positive genetic testing in this population. METHODS AND RESULTS: Prevalence of ATTRv in elderly ATTR-CM patients (≥70 years) was assessed in a cohort of 300 consecutive ATTR-CM patients (median age 78 years at diagnosis, 82% ≥70 years, 16% female, 99% Caucasian). ATTRv was diagnosed in 35 (12%; 95% confidence interval [CI] 3.1-8.8) and 13 (5.3%; 95% CI 5.6-26.7) patients in the overall cohort and in those ≥70 years, respectively. Prevalence of ATTRv among elderly female patients with ATTR-CM was 13% (95% CI 2.1-23.5). Univariate analysis identified female sex (odds ratio [OR] 3.66; 95% CI 1.13-11.85; p = 0.03), black ancestry (OR 46.31; 95% CI 3.52-Inf; p = 0.005), eye symptoms (OR 6.64; 95% CI 1.20-36.73; p = 0.03) and polyneuropathy (OR 10.05; 95% CI 3.09-32.64; p < 0.001) as the only factors associated with ATTRv in this population. Diagnosis of ATTRv in elderly ATTR-CM patients allowed initiation of transthyretin-specific drug treatment in 5 individuals, genetic screening in 33 relatives from 13 families, and identification of 9 ATTRv asymptomatic carriers. CONCLUSIONS: Hereditary transthyretin amyloidosis is present in a substantial number of ATTR-CM patients aged ≥70 years. Identification of ATTRv in elderly patients with ATTR-CM has clinical meaningful therapeutic and diagnostic implications. These results support routine genetic testing in patients with ATTR-CM regardless of age.

Patients with Type 2 diabetes mellitus (T2DM) and coronary artery disease (CAD) are at high risk of developing major adverse cardiovascular events (MACE). This is a multicenter, retrospective, and observational study performed in Spain aimed to characterize these patients in a real-world setting. Unstructured data from the Electronic Health Records were extracted by EHRead®, a technology based on Natural Language Processing and machine learning. The association between new MACE and the variables of interest were investigated by univariable and multivariable analyses. From a source population of 2,184,662 patients, we identified 4072 adults diagnosed with T2DM and CAD (62.2% male, mean age 70 ± 11). The main comorbidities observed included arterial hypertension, hyperlipidemia, and obesity, with metformin and statins being the treatments most frequently prescribed. MACE development was associated with multivessel (Hazard Ratio (HR) = 2.49) and single coronary vessel disease (HR = 1.71), transient ischemic attack (HR = 2.01), heart failure (HR = 1.32), insulin treatment (HR = 1.40), and percutaneous coronary intervention (PCI) (HR = 2.27), whilst statins (HR = 0.73) were associated with a lower risk of MACE occurrence. In conclusion, we found six risk factors associated with the development of MACE which were related with cardiovascular diseases and T2DM severity, and treatment with statins was identified as a protective factor for new MACE in this study.
