Chest Computed Tomography for Lymphoma Staging: A Wasted Opportunity for Cardiovascular Risk Stratification?

AIM: Patients with a lymphoma diagnosis undergo non-gated chest computed tomography (CT) scans as part of cancer diagnosis or staging. Although coronary artery calcification (CAC) is traditionally evaluated on dedicated cardiac CT, CAC can also be detected on standard chest CT. This exploratory study aimed to determine the prognostic value of CAC detected on non-gated chest CT and to report its use on clinical practice. METHOD: Consecutive patients with a lymphoma diagnosis who performed non-contrasted non-gated chest CT for cancer diagnosis or staging were included and retrospectively evaluated. Coronary artery calcification was evaluated by quantitative (Agatston score) and qualitative (visual) assessment. RESULTS: Fifty-seven patients were included in this study (mean age 61±15 years; 58% male). Coronary artery calcification was identified in 22 patients (39%), most of them with multi-vessel involvement. Coronary artery calcification was qualitatively classified as mild, moderate and severe in 11%, 19% and 9% patients, respectively. This study suggested that moderate or severe CAC was an independent predictor of all-cause mortality (odds ratio 3, 95% confidence interval 2-11; p=0.04) after adjusting for cardiovascular risk factors and lymphoma staging. Regarding quantitative evaluation, a higher CAC score was also associated with higher mortality. While significant CAC was identified in 22 patients, it was only reported in four patients. CONCLUSIONS: The preliminary findings of this hypothesis-generating study support the investigation of CAC identified by chest CT for diagnosis/staging of cancer as a risk modifier in the global risk assessment of patients with lymphoma. The unrecognition and underreporting of this finding may represent a wasted opportunity to detect subclinical coronary atherosclerosis in these patients and may help in guiding preventive cardiology care.

Coronary Artery Calcium Identified on Non-Gated Chest CT Scans: A Wasted Opportunity for Preventive Cardiological Care.

BACKGROUND: Coronary artery calcium (CAC) evaluated on dedicated cardiac computed tomography (CT) is an independent predictor of cardiovascular events. This study aimed to evaluate the correlation between CAC detected on non-gated standard chest CT and coronary lesions on coronary angiography (CAG) and determine its impact on prognosis. METHODS: Consecutive patients who underwent CAG due to acute coronary syndrome and had prior non-contrasted non-gated chest CT were included and retrospectively evaluated. Coronary artery calcium was evaluated by quantitative (Agatston score) and qualitative (visual assessment) assessment. RESULTS: A total of 114 patients were included in this study. The mean time difference between chest CT and CAG was 23 months. Coronary artery calcium was visually classified as mild, moderate, and severe in 31%, 33%, and 16% of patients, respectively. Moderate or severe CAC was an independent predictor of significant lesions on CAG (OR 22; 95% CI 8-61; p<0.001) and all-cause mortality (OR 4; 95% CI 2-9; p=0.001). Quantitative CAC evaluation accurately predicted significant lesions on CAG (AUC 0.81; p<0.001). While significant CAC was identified in 80% of chest CTs, formal reporting was 25%. CONCLUSION: Coronary artery calcium evaluation with chest CT was feasible and strongly associated with severity of coronary disease on CAG and mortality. Although the identification of CAC on chest CT represents a unique opportunity for cardiovascular risk stratification for preventive care, CAC underreporting is frequent.

Effects of radial artery spasm prophylaxis on intracoronary vasomotor responses during acetylcholine spasm provocation testing.

BACKGROUND: Invasive coronary angiography via the radial approach is commonly performed following radial artery spasm prophylaxis (RASP). It is however unknown, whether RASP influences the results of coronary spasm provocation testing performed after diagnostic angiography. We aimed to investigate the effects of RASP on vasomotor responses during intracoronary acetylcholine (ACh) testing. METHODS: We retrospectively screened 372 consecutive patients (51 % female, mean age 61 ±â€¯11 years) with angina and non-obstructive coronary arteries, who underwent intracoronary provocation with ACh according to a standardized protocol. During testing, dose-dependent clinical discomfort and concomitant ischemic electrocardiographic changes were recorded in addition to visual reductions of epicardial lumen diameters. Of these patients, 156 (42 %) received RASP (i.e. 200 µg nitroglycerin and 2.5 mg verapamil), while no RASP was administered in 216 (58 %) patients. Both groups were compared regarding age, sex, cardiovascular risk factors and ACh-test results. RESULTS: ACh provocation testing revealed a pathological test result in 71 patients (46 %) with RASP and 103 patients (48 %) without (p = 0.752) [epicardial spasm: in 20 patients (28 %) with RASP and 42 patients (41 %) without (p = 0.120); microvascular spasm: in 51 patients (72 %) with RASP and 61 patients (59 %) without (p = 0.362)]. Overall, RASP did not significantly alter coronary artery vasomotor responses, neither regarding the frequency (p = 0.752) or type of coronary spasm (microvascular vs. epicardial; p = 0.108) nor regarding the ACh dose leading to spasm (p = 0.151). CONCLUSIONS: RASP does not significantly affect coronary vasomotor responses to ACh, suggesting that radial artery spasm prophylaxis can be routinely administered even in patients in whom intracoronary spasm testing is performed.

How to predict prognosis in patients with acute pulmonary embolism? Recent advances.

Pulmonary embolism (PE) is the third most frequent cardiovascular disease, characterized by a wide range of presentations and clinical courses. Prognostic assessment is a cornerstone of PE management as it determines the choice of both diagnostic and therapeutic strategies. During the previous decades significant efforts have been made to safely select patients for early discharge or home treatment, but appropriate risk stratification, particularly of intermediate-risk patients, remains challenging. In addition to the guideline-recommended clinical prediction rules, such as Pulmonary Embolism Severity Index (PESI), simplified PESI (sPESI), and/or Hestia criteria, a multimodality approach based also on biomarkers and cardiac imaging is crucial for risk-stratification and for selecting appropriate management of patients. In this review article, we discuss the current methods for predicting short and long-term prognosis in PE patients, focusing on the current guidelines, but also on the most recently proposed clinical prediction rules, biomarkers, and imaging parameters.

Cardiovascular Health Metrics Differ Between Individuals With and Without Cancer.

BACKGROUND: Although individuals with cancer experience high rates of cardiovascular morbidity, there are limited data on the potential differences in cardiovascular health (CVH) metrics between individuals with and without cancer. METHODS AND RESULTS: The National Health and Nutrition Examination Survey between 2015 and 2020 was queried to evaluate the prevalence of health metrics that comprise the American Heart Association Life's Essential 8 construct of cardiovascular health among adult individuals with and without cancer in the United States. Health metric scores were also evaluated according to important patient demographics including age, sex, race and ethnicity, and socioeconomic status. Among 4370 participants representing >180 million US adults, 9.4% had a history of cancer. Individuals with cancer had lower overall cardiovascular health scores (67.1 versus 69.1, P<0.001) compared with individuals without cancer. Among individual components of the cardiovascular health score, those with cancer had better health scores on key behaviors including physical activity, diet, and sleep compared with those without cancer, although variation was noted based on age. Higher scores on these modifiable health behaviors among those with cancer compared with those without cancer were noted in older individuals, in White individuals compared with other races and ethnicities, and in individuals with higher socioeconomic status. CONCLUSIONS: We highlight important variations in simple cardiovascular health metrics among individuals with cancer compared with individuals without cancer and demonstrate differences among health metrics based on age, race and ethnicity, and socioeconomic status. These findings may explain ongoing racial, ethnic, and socioeconomic status disparities in the cancer population and provide a framework for optimizing cardiovascular health among individuals with cancer.

Rapidly Progressive Coronary Aneurysm: A Rare Case of Isolated Coronary Vasculitis With Recurrent Myocardial Infarction.

Isolated coronary arteritis without systemic involvement in adults is exceedingly rare. A 60-year-old patient developed recurrent non-ST-segment elevation myocardial infarctions for 1 year. After an initial coronary angiogram that was normal, serial angiograms showed de novo aneurysm formation. The patient responded favorably to corticosteroids, supporting the diagnosis of isolated coronary arteritis. (Level of Difficulty: Intermediate.).

Predictors of coronary artery disease in cardiac arrest survivors: coronary angiography for everyone? A single-center retrospective analysis. / Preditores de doença arterial coronária em sobreviventes à parada cardíaca: angiografia coronária para todos? Uma análise retrospectiva em centro único.

OBJECTIVE: To identify predictors of coronary artery disease in survivors of cardiac arrest, to define the best timing for coronary angiography and to establish the relationship between coronary artery disease and mortality. METHODS: This was a single-center retrospective study including consecutive patients who underwent coronary angiography after cardiac arrest. RESULTS: A total of 117 patients (63 ± 13 years, 77% men) were included. Most cardiac arrest incidents occurred with shockable rhythms (70.1%), and the median duration until the return of spontaneous circulation was 10 minutes. Significant coronary artery disease was found in 68.4% of patients, of whom 75% underwent percutaneous coronary intervention. ST-segment elevation (OR 6.5, 95%CI 2.2 - 19.6; p = 0.001), the presence of wall motion abnormalities (OR 22.0, 95%CI 5.7 - 84.6; p < 0.001), an left ventricular ejection fraction ≤ 40% (OR 6.2, 95%CI 1.8 - 21.8; p = 0.005) and elevated high sensitivity troponin T (OR 3.04, 95%CI 1.3 - 6.9; p = 0.008) were predictors of coronary artery disease; the latter had poor accuracy (area under the curve 0.64; p = 0.004), with an optimal cutoff of 170ng/L. Only ST-segment elevation and the presence of wall motion abnormalities were independent predictors of coronary artery disease. The duration of cardiac arrest (OR 1.015, 95%CI 1.0 - 1.05; p = 0.048) was an independent predictor of death, and shockable rhythm (OR 0.4, 95%CI 0.4 - 0.9; p = 0.031) was an independent predictor of survival. The presence of coronary artery disease and the performance of percutaneous coronary intervention had no impact on survival; it was not possible to establish the best cutoff for coronary angiography timing. CONCLUSION: In patients with cardiac arrest, ST-segment elevation, wall motion abnormalities, left ventricular dysfunction and elevated high sensitivity troponin T were predictive of coronary artery disease. Neither coronary artery disease nor percutaneous coronary intervention significantly impacted survival.

OBJETIVO: Identificar os preditores de doença arterial coronária em sobreviventes à parada cardíaca, visando definir o melhor momento para realização de angiografia coronária e estabelecer o relacionamento entre doença arterial coronária e mortalidade. MÉTODOS: Este foi um estudo retrospectivo em centro único, que incluiu os pacientes consecutivamente submetidos à angiografia coronária após uma parada cardíaca. RESULTADOS: Incluímos 117 pacientes (63 ± 13 anos, 77% homens). A maioria dos incidentes de parada cardíaca ocorreu com ritmos chocáveis (70,1%), e o tempo mediano até retorno da circulação espontânea foi de 10 minutos. Identificou-se doença arterial coronária em 68,4% dos pacientes, dentre os quais 75% foram submetidos à intervenção coronária percutânea. Elevação do segmento ST (RC de 6,5; IC95% 2,2 - 19,6; p = 0,001), presença de alterações da contratilidade segmentar (RC de 22,0; IC95% 5,7 - 84,6; p < 0,001), fração de ejeção ventricular esquerda ≤ 40% (RC de 6,2; IC95% 1,8 - 21,8; p = 0,005) e níveis elevados de troponina T de alta sensibilidade (RC de 3,04; IC95% 1,3 - 6,9; p = 0,008) foram preditores de doença arterial coronária; esse último teve baixa precisão (área sob a curva de 0,64; p = 0,004), tendo o nível de 170ng/L como ponto ideal de corte. Apenas elevação do segmento ST e presença de alterações da contratilidade segmentar foram preditores independentes de doença arterial coronária. A duração da parada cardíaca (RC de 1,015; IC95% 1,0 - 1,05; p = 0,048) foi um preditor independente de óbito, e ritmo chocável (RC de 0,4; IC95% 0,4 - 0,9; p = 0,031) foi um preditor independente de sobrevivência. A presença de doença arterial coronária e a realização de intervenção coronária percutânea não tiveram impacto na sobrevivência; não foi possível estabelecer o melhor ponto de corte para o momento da angiografia coronária. CONCLUSÃO: Em pacientes com parada cardíaca, elevação do segmento ST, alterações da contratilidade segmentar, disfunção ventricular esquerda e níveis elevados de troponina T de alta sensibilidade foram preditivos de doença arterial coronária. Nem doença arterial coronária nem a intervenção coronária percutânea tiveram impacto significante na sobrevivência.

The sensitivity of DPD scintigraphy to detect transthyretin cardiac amyloidosis in V30M mutation depends on the phenotypic expression of the disease.

Background: There is a growing need for a non-invasive test to detect cardiac involvement in patients with transthyretin-related hereditary amyloidosis (ATTR) caused by V30M mutation. 99mTc-3,3-diphosphono-1,2-propanodicarboxylic acid (DPD) scintigraphy is a promising method, but its accuracy in this particular mutation remains unknown.Methods: A cohort of 179 patients: 92 with early-onset disease (EoD, symptoms <50-years-old), 33 with late-onset disease (LoD) and 54 asymptomatic carriers were prospectively evaluated and underwent DPD scintigraphy, which was compared with the results of echocardiogram, ambulatory blood pressure monitoring, 24 h-Holter, myocardial 123I-metaiodobenzylguanidine imaging and NT-proBNP.Results: Amyloid cardiomyopathy, defined as septal thickness ≥13 mm, was present in 32 patients (17.9%) and was more frequent in those with LoD (OR: 3.68, p = .003). Cardiac DPD uptake was present in 22 individuals (12.3%) and correlated with parameters indicative of cardiac amyloidosis. DPD imaging was strongly influenced by the age of disease onset: among patients with myocardial thickening, cardiac DPD retention was present in 11/15 (73.3%) with LoD, in contrast to only 4/17 (26.7%) with EoD (p = .005). Two patients with myocardial thickening and normal DPD scintigraphy underwent endomyocardial biopsy that confirmed ATTR amyloidosis.Conclusion: DPD scintigraphy presents suboptimal sensitivity to detect cardiac involvement in ATTRV30M, particularly in symptomatic patients with EoD.

Radial versus femoral approach for left ventricular endomyocardial biopsy.

AIMS: Despite the widespread use of the radial approach in coronary interventions, left ventricular endomyocardial biopsy (LV-EMB) is most frequently performed via the femoral artery. We sought to assess the feasibility and safety of radial compared to femoral access in a large cohort of patients undergoing LV-EMB. METHODS AND RESULTS: Data from 264 patients who underwent LV-EMB in Germany, Portugal, Japan and Canada were collected. Clinical, procedural, safety and feasibility data were evaluated and compared between the two groups. LV-EMB was successfully performed by the radial approach in 129 (99%) of 130 and in 134 (100%) patients by the femoral access. Patients in the radial group were older (mean age 55.7 versus 44.3 years) and were more likely to have moderate-severe mitral regurgitation (27.7% versus TF 0%). Sheathless guides were used in 108 (83.1%) of the radial and 2 (1.5%) of the femoral patients, so the mean guiding catheter size (radial 7.0±1.0 Fr versus femoral 8.0±0.0 Fr) was significantly smaller in the radial group (p<0.001). Mild or moderate radial artery spasm occurred in 13 (10.0%) patients but only one (0.8%) patient required conversion to femoral access due to severe spasm. No access site-related complications were reported in the radial group, while 11 (8.2%) patients in the femoral group had access-site haematomas (p=0.001). There were no major complications (mitral valve injury, pericardial tamponade requiring intervention, cerebrovascular accidents, persistent high-degree atrioventricular block, major bleeding or death) in either group. CONCLUSIONS: The radial approach for LV-EMB appears to be safe and associated with a high success rate while possibly leading to fewer access-site bleeding complications compared to the femoral access. The results of this international multicentre study support the radial approach for LV-EMB and further inspire the expansion of "radial first" in the field of interventional cardiology.

A rare case of concomitant stress (takotsubo) cardiomyopathy and acute myocardial infarction.

Stress cardiomyopathy and myocardial infarction are generally regarded as mutually exclusive diagnoses. We report the case of a 54-year-old woman who presented with acute chest pain. Her echocardiogram and ventriculography were typical of stress cardiomyopathy, but she had one subocclusive coronary lesion, a highly significant rise in troponin and a subendocardial myocardial infarction scar documented on cardiac magnetic resonance. This is a rare case of concomitant myocardial infarction and stress cardiomyopathy, in which the acute coronary syndrome itself may have been the stressor, given the absence of other identifiable causes.

[Career Satisfaction of Medical Residents in Portugal]. / Satisfação com a Especialidade entre os Internos da Formação Específica em Portugal.

INTRODUCTION: The satisfaction with the medical profession has been identified as an essential factor for the quality of care, the wellbeing of patients and the healthcare systems' stability. Recent studies have emphasized a growing discontent of physicians, mainly as a result of changes in labor relations. OBJECTIVES: To assess the perception of Portuguese medical residents about: correspondence of residency with previous expectations; degree of satisfaction with the specialty, profession and place of training; reasons for dissatisfaction; opinion regarding clinical practice in Portugal and emigration intents. MATERIAL AND METHODS: Cross-sectional study. Data collection was conducted through the "Satisfaction with Specialization Survey", created in an online platform, designed for this purpose, between May and August 2014. RESULTS: From a total population of 5788 medical residents, 804 (12.25 %) responses were obtained. From this sample, 77% of the responses were from residents in the first three years. Results showed that 90% of the residents are satisfied with their specialty, 85% with the medical profession and 86% with their place of training. Nevertheless, results showed a decrease in satisfaction over the final years of residency. The overall assessment of the clinical practice scenario in Portugal was negative and 65% of residents have plans to emigrate after completing their residency. CONCLUSION: Portuguese residents revealed high satisfaction levels regarding their profession. However, their views on Portuguese clinical practice and the results concerning the intent to emigrate highlight the need to take steps to reverse this scenario.
