RESUMO
BACKGROUND AND OBJECTIVES: A relationship between neoplasms and Takotsubo syndrome (TS) has been postulated. Our goal was to determine its prevalence in patients with TS, compare the clinical profile of TS with or without cancer and study its long-term evolution. MATERIALS AND METHODS: The oncological situation of patients included in the National Registry on TAKOtsubo syndrome (RETAKO), admitted between 2002 and 2019, provided by 38 hospitals throughout the country is analysed. Any history of malignancy or tumour, even benign, that received chemotherapy, radiotherapy or specific surgery, current or past, was considered. RESULTS: Any type of neoplasm was described in 129 (11.8%), within a cohort of 1,097 patients with TS. The cohort of patients with neoplasm, with a lower percentage of women (79.1 vs. 88.3%; P=.003), showed a non-significant tendency at an older age, hyperuricaemia, sleep apnoea and lower LVEF on admission, with a similar cardiovascular risk factor profile, but more chronic anaemia and immunosuppression. The most common neoplasm was breast cancer. During their hospital stay, the cancer patients suffered more complications, highlighting heart failure/shock, acute renal failure and a trend towards combined infections. On follow-up, they presented higher mortality and more combined MACE events, with a non-significant trend in the occurrence of cardiovascular recurrences or readmissions. CONCLUSIONS: The prevalence of neoplasms in patients with TS is high. The clinical presentation is different in relation to patients who do not have neoplasms and they probably represent a risk factor for a worse hospital and long term prognosis.

INTRODUCTION AND OBJECTIVES: Rotational coronary angiography (RCA) requires less contrast to be administered and can prevent the onset of contrast-induced nephropathy (CIN) during invasive coronary procedures. The aim of the study is to evaluate the impact of RCA on CIN (increase in serum creatinine ≥0.5mg/dl or ≥25%) after an acute coronary syndrome. METHODS: From April to September 2016, patients suffering acute coronary syndromes who underwent diagnostic coronary angiography, with the possibility of ad hoc coronary angioplasty, were prospectively enrolled. At the operator's discretion, patients underwent RCA or conventional coronary angiography (CCA). CIN (primary endpoint), as well as analytical, angiographic and clinical endpoints, were compared between groups. RESULTS: Of the 235 patients enrolled, 116 patients received RCA and 119 patients received CCA. The RCA group was composed of older patients (64.0±11.8 years vs. 59.7±12.1 years; p=0.006), a higher proportion of women (44.8 vs. 17.6%; p<0.001), patients with a lower estimated glomerular filtration rate (76±25 vs. 86±27ml/min/1.73 m2; p=0.001), and patients who underwent fewer coronary angioplasties (p<0.001) compared with the CCA group. Furthermore, the RCA group, received less contrast (113±92 vs. 169±103ml; p<0.001), including in diagnostic procedures (54±24 vs. 85±56ml; p<0.001) and diagnostic-therapeutic procedures (174±64 vs. 205±98ml; p=0.049) compared with the CCA group. The RCA group presented less CIN (4.3 vs. 22.7%; p<0.001) compared to the CCA group, and this finding was maintained in the regression analysis (Adjusted relative risk: 0.868; 95% CI: 0.794-0.949; p=0.002). There were no differences in clinical endpoints between the groups. CONCLUSIONS: RCA was associated with lower administration of contrast during invasive coronary procedures in acute coronary syndrome patients, resulting in lower incidence of CIN, in comparison with CCA.

Resumen Objetivo: Durante el período de formación, el residente de cardiología ha de entrenarse en todo lo relacionado con la indicación, la interpretación y realización de imágenes en cardiología nuclear que usan la tomografía computarizada por emisión de fotón simple (SPECT). El objetivo del presente estudio fue analizar la relación existente entre la adecuación de las indicaciones del gated-SPECT de perfusión miocárdica y los años de experiencia desde la finalización de la residencia de cardiología. Método: Registro descriptivo, retrospectivo y unicéntrico, en el que se analizaron las indicaciones (uso adecuado e inadecuado), según las guías de la gated-SPECT de perfusión miocárdica, prescritas por cardiólogos de un hospital universitario. Resultados: Se analizaron un total de 950 pruebas de gated-SPECT de acuerdo a la indicación adecuada e inadecuada y se distribuyeron por cuartiles los años de finalización de la residencia del cardiólogo prescriptor. Los cardiólogos de menos de 10 años de experiencia clínica indican de forma inadecuada una mayor proporción de pruebas de gated-SPECT que los cardiólogos de mayor experiencia (87,6 vs. 9,3%: p < 0,001). Tras ajustar por edad, sexo y factores de riesgo cardiovascular, el análisis multivariante mostró que por cada año de experiencia tras finalizar la residencia de cardiología aumenta un 33% la probabilidad de indicar de forma adecuada la prueba (OR: 1,33; IC 95%: 1,29-1,38; p < 0,001). Conclusiones: La experiencia profesional del cardiólogo clínico es el factor más importante para realizar una indicación adecuada de la gated-SPECT de perfusión miocárdica.
Abstract Objective: During cardiology training, the cardiology fellow has to be trained in all things related to the indication, interpretation, and performing of nuclear cardiology studies using single photon emission computed tomography (SPECT). The aim of the present study was to analyse the relationship between the adequacy of indications of myocardial perfusion gated-SPECT and the years of experience since the completion of cardiology training. Method: A descriptive, retrospective analysis was performed on a single-centre register, in which the indications (adequate or inadequate use) were recorded according to myocardial perfusion gated-SPECT guidelines, prescribed by cardiologists of a university hospital. Results: A total of 950 gated-SPECT tests were analysed according to the appropriate or inade- quate indication. The sample of study was distributed in quartiles (years) since the cardiologist finished the residency. Cardiologists with less than 10 years of clinical experience reported a higher proportion of gated-SPECT tests compared to the more experienced cardiologists (87.6 vs. 9.3%, P < .001). After adjusting for age, gender, and cardiovascular risk factors, the multiva- riate analysis showed that, for each year of experience after completion of cardiology training, the probability of adequately indicating the test (OR: 1.33, 95% CI: 1.29-1.38, P < .001) was statistically significant. Conclusions: The professional experience of the clinical cardiologist is the most important factor to perform an appropriate indication of gated-SPECT myocardial perfusion.

BACKGROUND: Takotsubo syndrome (TKS) usually mimics an acute coronary syndrome. However, several clinical forms have been reported. Our aim was to assess if different stressful triggers had prognostic influence on TKS, and to establish a working classification. METHODS: We performed an analysis including patients with TKS between 2003-2013 from our prospective local database and the RETAKO National Registry, fulfilling Mayo criteria. Patients were divided in two groups regarding their potential triggers: (a) none/psychic stress as 'primary forms' and (b) physical factors (asthma, surgery, trauma, etc.) as 'secondary forms'. RESULTS: Finally, 328 patients were included, 90.2% women, with a mean age of 69.7 years. Patients were divided into primary TKS (n=265) and 63 secondary TKS groups. Age, gender, previous functional class and cardiovascular risk profile displayed no differences between groups before admission. However, primary-TKS patients suffered a main complaint of chest pain (89.4% vs 50.7%, p<0.0001) with frequent vegetative symptoms. Regarding treatment before admission, there were no differences either. During admission, differences were related to more intensive antithrombotic and anxiolytic drug use in the primary TKS group. Inotropic and mechanical ventilation use was higher in the secondary cohort. After discharge, a more frequent prescription of beta-blockers and statins in primary-TKS patients was seen. Secondary forms displayed more in-hospital stay and evolutive complications: death (hazard ratio (HR): 3.41; 95% confidence interval (CI): 1.14-10.16, p=0.02), combined event variable (MACE) (HR: 1.61; 95% CI: 1.01-2.6, p=0.04) and recurrences (HR: 1.85; 95% CI: 1.06-3.22, p=0.02). CONCLUSION: Secondary TKS could present or mark worse short and long-term prognoses in terms of mortality, recurrences and readmissions. We propose a simple working nomenclature for TKS.

INTRODUCTION AND AIMS: The etiology and epidemiology of tako-tsubo cardiomyopathy remain uncertain. The symptoms of this condition are often similar to those of myocardial infarction and, although it usually has a good prognosis, it is not without complications. Our aim was to characterize this disease in our setting using a dedicated registry (Spanish REgistry for TAKOtsubo cardiomyopathy). METHODS: The prospective registry included 202 incident patients in 23 hospitals from 2012 to 2013. The patients' clinical characteristics and analytical, echocardiographic, and imaging results were recorded, as were the events during follow-up. Patients were included when the attending physician considered the case proven, and incidence was calculated relative to the catheterizations requested for a presumptive diagnosis of acute coronary syndrome. RESULTS: The patients were predominantly women (90%), with a mean age of 70 years, and many had cardiovascular risk factors, such as hypertension (67%), dyslipidemia (41%), diabetes mellitus (15%), and smoking (15%). The incidence of tako-tsubo cardiomyopathy was 1.2%, and there was no clear weekly or seasonal distribution pattern. Chest pain was the predominant symptom, a triggering factor (emotional, physical, or both) was present in 72%, and most patients consulted within the first 6h after symptom onset. The median duration of hospitalization was 7 days. There were heart failure symptoms in 34.0%, arrhythmia in 26.7%, and 2.4% of patients died. CONCLUSIONS: The incidence of tako-tsubo cardiomyopathy is low. This disease primarily affects postmenopausal women, and occurs after a situation of emotional stress in more than half of affected individuals. It is characterized by anginal pain, shows no seasonal distribution, and has a good prognosis, although it is not without morbidity and mortality.
