RESUMO
INTRODUCTION AND OBJECTIVE: Several scoring systems have been developed for risk stratification in patients with acute pulmonary embolism (PE). The Pulmonary Embolism Severity Index (PESI) and its simplified version (sPESI) are among the most used, however the high number of variables hinder its application. Our aim was to derive an easy-to-perform score based on simple parameters obtained at admission to predict 30-day mortality in acute PE patients. METHODS: Retrospective study in 1115 patients with acute PE from two institutions (derivation cohort n=835, validation cohort n=280). The primary endpoint was all-cause mortality at 30 days. Statistically and clinically relevant variables were selected for multivariable Cox regression analysis. We derived and validated a multivariable risk score model and compared to other established scores. RESULTS: The primary endpoint occurred in 207 patients (18.6%). Our model included five variables weighted as follows: modified shock index ≥1.1 (hazard ratio [HR] 2.57, 1.68-3.92, p<0.001), active cancer (HR 2.27, 1.45-3.56, p<0.001), altered mental state (HR 3.82, 2.50-5.83, p<0.001), serum lactate concentration ≥2.50 mmol/L (HR 5.01, 3.25-7.72, p<0.001), and age ≥80 years (HR 1.95, 1.26-3.03, p=0.003). The prognostic ability was superior to other scores (area under curve [AUC] 0.83 [0.79-0.87] vs 0.72 [0.67-0.79] in PESI and 0.70 [0.62-0.75] in sPESI, p<0.001) and its performance in the validation cohort was deemed good (73 events in 280 patients, 26.1%, AUC=0.76, 0.71-0.82, p<0.0001) and superior to other scores (p<0.05). CONCLUSIONS: The PoPE score (https://tinyurl.com/ybsnka8s) is an easy tool with superior performance to predict early mortality in patients admitted for PE with non-high-risk PE.

AIMS: Many European healthcare providers struggle to adopt multidisciplinary, integrated care pathways for people with heart failure (HF) as recommended by the European Society of Cardiology. PRO-HF (Program to Optimize Heart Failure Patient Pathways) was developed to help clinicians identify strengths, gaps, and shortcomings in their HF pathways and support tailored interventions to optimize pathways and enhance patient care. We report initial findings from baseline assessments of HF pathway characteristics and challenges from 10 hospitals in six European countries (France, Ireland, Portugal, Spain, The Netherlands, and United Kingdom). METHODS AND RESULTS: Baseline assessments were holistic appraisals of full HF services to calibrate current status and development needs and assist management teams in prioritizing improvement projects. Assessments were performed using a comprehensive checklist of measures covering the HF patient journey from diagnosis to ongoing follow-up. These included a digital survey sent to full HF care teams and one-to-one interviews. The digital survey focused on four key areas (HF outpatient clinic; remote patient management; efficient device implantation and inpatient pathways; and network maximization) and 16 dimensions of excellence. Priority areas and themes for action identified in baseline assessments were (i) provision of HF specialist care; (ii) data capture and analysis; (iii) institutional care protocols; (iv) hospital-wide strategies; and (v) multidisciplinary teams (MDTs). Suboptimal specialist care of emergency inpatients was an issue at all hospitals and prioritized at 8/10. Availability and accessibility of data on patients, activities, and outcomes was an issue at all hospitals and prioritized by 4/10. A lack of clear protocols, templates, and tools for some HF activities created variability in patient care (e.g., HF specialist consultations, diagnostic testing, follow-up appointments, medications, and device eligibility) and inefficient use of clinician time. This made it difficult to initiate new technologies (e.g., remote patient monitoring) due to the risk of overburdening staff. MDTs were frequently understaffed. Multiple interventions were identified to address gaps and shortcomings that could be tailored to specific needs of individual hospitals (e.g., inpatient pathway optimization, creation/optimization of HF outpatient clinics, development of an HF performance dashboard, enhancement of protocol adherence, streamlining cardiac resynchronisation therapy pathways, and MDT coordination). CONCLUSIONS: PRO-HF provides a valuable opportunity to identify gaps and significant shortcomings in HF pathways in European hospitals. Preliminary findings from hospitals that have initiated suggested changes to address these challenges are encouraging, though longer-term follow-up from more hospitals is needed to confirm the impact of PRO-HF on HF pathway optimization and patient care.
RESUMO
Acute myocarditis (especially) and pericarditis have been consistently associated with the administration of vaccines against SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2), generating anxiety in the general population, uncertainty in the scientific community and obstacles to ambitious mass vaccination programs, especially in foreign countries. Like some of its European counterparts, the Portuguese Society of Cardiology (SPC), through its Studies Committee, decided to take a position on some of the most pressing questions related to this issue: (i) How certain are we of this epidemiological association? (ii) What is the probability of its occurrence? (iii) What are the pathophysiological bases of these inflammatory syndromes? (iv) Should their diagnosis, treatment and prognosis follow the same steps as for typical idiopathic or post-viral acute myopericarditis cases? (v) Is the risk of post-vaccine myocarditis great enough to overshadow the occurrence of serious COVID-19 disease in unvaccinated individuals? In addition, the SPC will issue clinical recommendations and offer its outlook on the various paths this emerging disease may take in the future.

INTRODUCTION: Left ventricular thrombus commonly occurs as a complication of acute anterior myocardial infarction and nonischemic cardiomyopathies with severe left ventricular systolic dysfunction. Its frequency is still high despite medical advances. Current guidelines recommend the use of vitamin k antagonists as first-line therapy, however, the off-label use of direct oral anticoagulants is becoming more frequent and attractive, given the better pharmacological and clinical profile, with the improvement of the patient's quality of life. AIM: To provide an update on the currently existing evidence regarding the outcomes of efficacy and safety of direct oral anticoagulants (DOACs) as first-line therapy in left ventricular thrombus, in comparison to vitamin K antagonists (VKAs). METHODS: A systematic review and meta-analysis of studies on the effects of direct oral anticoagulants versus vitamin K antagonists on left ventricular thrombi and on the results was performed. RESULTS: Fourteen studies were included in the meta-analysis, with a total of 2498 patients (n=631 direct oral anticoagulants and n=1867 for VKAs). No significant differences were found in efficacy and safety outcomes (odds ratio (OR) 0.86; 95% confidence interval (CI), 0.55-1.33; p=0.50; I2=32%) and (OR 1.0; 95% CI, 0.78-1.30; p=0.93; I2=2%) respectively. No difference was noted in all-cause mortality (OR 0.92; 95% CI, 0.58-1.45; p=0.74; I2=0%). Thrombus resolution was observed in 288/416 in direct oral anticoagulants vs. 732/1085 patients treated with VKAs (OR 1.14; 95% CI, 0.77-1.66; p=0.50; I2=33%). CONCLUSIONS: The findings of this meta-analysis suggest the potential utility of DOACs as a first-line strategy in patients with left ventricular thrombus.

Kounis syndrome is an acute coronary syndrome occurring in the setting of a hypersensitivity reaction. It occurs as a consequence of mast-cell activation and degranulation causing coronary artery spasm, atherosclerotic plaque erosion, or stent thrombosis. We report the case of a man who presented to the emergency department with typical angina that started 20 minutes after coronavirus disease 2019 (COVID-19) vaccine administration. Electrocardiogram showed inferior ST-elevation myocardial infarction, and coronary angiography confirmed right coronary artery stent thrombosis. Five months before, he had an acute coronary syndrome after influenza vaccine administration. Both vaccines share a common excipient, polysorbate 80. Considering the reproducibility of the reaction and the temporal association between vaccine administration and coronary events, a hypersensitivity reaction to polysorbate 80 was admitted and the patient was instructed to further avoid drugs containing it. To our knowledge, this constitutes the first reported case of type 3 Kounis syndrome after COVID-19 vaccine administration. Kounis syndrome is an uncommon disease, often undiagnosed. Its recognition and proper management are crucial to prevent future events.
RESUMO
BACKGROUND: Patients undergoing heart valve surgery are routinely evaluated for the presence of coronary artery disease (CAD). Currently, concomitant valve intervention and surgical revascularization is recommended when there is obstructive CAD. The aim of our study was to evaluate the prevalence of CAD, its treatment strategies, and their prognostic implications in a contemporary population of patients with valvular heart disease (VHD) referred for valve surgery (HVS). METHODS: In a multicenter registry, consecutive patients with formal indication for HVS referred for a preoperative routine invasive coronary angiogram (ICA) were analyzed. Baseline characteristics, CAD prevalence and revascularization patterns, as well as their impact on short and mid-term all-cause mortality, were assessed. RESULTS: Overall, 1133 patients were included; most had aortic stenosis (69%) and obstructive CAD was present in 307 (27.1%). HVS was ultimately performed in 82.3%. In patients with CAD, 53.4% were revascularized. After a mean follow-up time of 29.06±18.46 months, all-cause mortality rate was 12.9%. In multivariate analysis, not having HVS (HR 6.845, 95% CI=4.281-10.947, P<0.001), obstructive CAD (HR 2.762, 95% CI=1.764-4.326, P<0.01), COPD (HR 2.043, 95% CI=1.014-4.197, P=0.022), and age (HR 1.030, 95% CI=1.009-1.063, P=0.047), were independent predictors of all-cause mortality. In patients with obstructive CAD who underwent HVS, revascularization was not significantly associated with survival (HR 2.127, 95% CI=0.0-4.494, P=0.048; log rank P=0.042). CONCLUSIONS: In a contemporary cohort of patients with VHD and surgical indication, overall obstructive CAD prevalence was 27%. CAD presence and severity were associated with higher mortality. However, revascularization was not associated with a survival benefit, except in patients with left anterior descending artery disease.

The authors describe a case of a patient admitted to the emergency department with diabetic ketoacidosis. Although there were no symptoms attributable to the cardiovascular system, lab tests revealed elevated troponin I and natriuretic peptides, coupled with repolarization abnormalities on the ECG. The transthoracic echocardiogram (TTE) showed a non-dilated left ventricle with severe left ventricular systolic dysfunction due to diffuse hypokinesia, and a concomitant diagnosis of profile L heart failure was proposed. Etiologic investigation was negative, and when a new TTE was performed seven days after the first, left ventricular function was normal. Although rarely considered, metabolic and electrolyte disorders, especially diabetic ketoacidosis, can be a cause of left ventricular systolic dysfunction, and should be considered in the differential diagnosis. This is another way diabetes can have an impact on the cardiovascular system.

INTRODUCTION AND OBJECTIVES: The Internet is a fundamental aspect of health information. However, the absence of quality control encourages misinformation. We aim to assess the relevance and quality of acute myocardial infarction videos shared on YouTube (www.youtube.com) in Portuguese. METHODS: We analyzed 1,000 videos corresponding to the first 100 search results on YouTube using the following terms (in Portuguese): "cardiac + arrest"; "heart + attack"; "heart + thrombosis"; "coronary + thrombosis"; "infarction - brain", "myocardial + infarction" and "acute + myocardial + infarction". Irrelevant (n=316), duplicated (n=345), without audio (n=24) or non-Portuguese (n=106) videos were excluded. Included videos were assessed according to source, topic, target audience and scientific inaccuracies. Quality of information was assessed using The Health on the Net Code (HONCode from 0 to 8) and DISCERN (from 0 to 5) scores - the higher the score, the better the quality. RESULTS: 242 videos were included. The majority were from independent instructors (n=95, 39.0%) and were addressed to the general population (n=202, 83.5%). One third of the videos (n=79) contained inaccuracies while scientific society and governmental/health institution videos had no inaccuracies. The mean video quality was poor or moderate; only one video was good quality without any inaccuracies. Governmental/health institutions were the source with the best quality videos (HONCode 4±1, DISCERN 2±1). CONCLUSIONS: One third of the videos had irrelevant information and one third of the relevant ones contained inaccuracies. The average video quality was poor; therefore it is important to define strategies to improve the quality of online health information.

RESUMO
AIM: To assess the temporal trends in the usage pattern of non-invasive testing before invasive coronary angiography (ICA) and its diagnostic yield in patients with suspected coronary artery disease (CAD). METHODS: Cross-sectional observational multicenter study of 4805 consecutive patients (60% male, mean age 66 ± 10 years) with suspected CAD undergoing elective ICA due to angina pectoris in two centers, from 2008 to 2017. The use of noninvasive testing and the proportion of patients with obstructive CAD (defined as the presence of at least one ≥50% stenosis on ICA) were assessed. RESULTS: There were 4038 (84%) patients referred for ICA with positive noninvasive test, mainly SPECT (38%, n = 1828) and exercise ECG (36%, n = 1731). Obstructive CAD was found in 54.5% (n = 2621) of the patients and 37.9% (n = 1822) underwent revascularization. The prevalence of obstructive CAD was higher in patients with vs. without previous noninvasive testing (55.8% vs. 48.1%, respectively, P < 0.001) and tended to decrease during the study period (P for trend <0.001). Both the presence of obstructive CAD and revascularization rate were higher in patients who underwent anatomical evaluation with CCTA compared with noninvasive functional tests (P = 0.001 and P = 0.018, respectively). The number of patients referred after exercise testing and SPECT decreased (p for trend 0.005 and 0.006, respectively) and after CCTA and stress CMR increased (both P for trend <0.001). The proportion of patients referred without previous testing remained stable. CONCLUSION: Nearly half of the patients undergoing ICA for suspected CAD did not have obstructive coronary lesions. This proportion tended to increase over the 10-year span of this study. Better clinical assessment tools and diagnostic pathways for stable CAD are warranted.

INTRODUCTION AND OBJECTIVES: Use of invasive physiological assessment in patients with coronary artery disease varies widely and is perceived to be low. We aimed to examine adoption rates as well as patterns and determinants of use in an unselected population undergoing invasive coronary angiography over a long time frame. METHODS: We retrospectively determined the per-procedure prevalence of physiological assessment in 40821 coronary cases performed between 2007 and 2018 in two large-volume centers. Adoption was examined according to procedure type and patient- and operator-related variables. Its association with relevant scientific landmarks, such as the release of clinical trial results and practice guidelines, was also assessed. RESULTS: Overall adoption was low, ranging from 0.6% in patients undergoing invasive coronary angiography due to underlying valve disease, to 6% in the setting of stable coronary artery disease (CAD); it was 3.1% in patients sustaining an acute coronary syndrome. Of scientific landmarks, FAME 1, the long-term results of FAME 2 and the 2014 European myocardial revascularization guidelines were associated with changes in practice. Publication of instantaneous wave-free ratio (iFR) trials had no influence on adoption rates, except for a higher proportion of iFR use. In 42.9% of stable CAD patients undergoing percutaneous coronary intervention there was no objective non-invasive evidence of ischemia, nor was physiological assessment performed. Younger operator age (4.5% vs. 4.0% vs. 0.9% for ages <40, 40-55 and >55 years, respectively; p<0.001) and later time of procedure during the day (2.9% between 6 and 8 p.m. vs. 4.4% at other times) were independent correlates of use of invasive physiology. CONCLUSIONS: Our study confirms the low use of invasive physiology in routine practice. The availability of resting indices did not increase adoption. Strategies are warranted to promote guideline implementation and to improve patient care and clinical outcomes.

RESUMO
INTRODUCTION: Coronary artery disease is becoming the leading cause of death in women in Western society. However, the available data shows that women are still underdiagnosed and undertreated with guideline-recommended secondary prevention therapy, leading to a significantly higher rate of in-hospital complications and in-hospital mortality. OBJECTIVE: The main objective of this work is to assess the approach to acute coronary syndrome (ACS) in Portugal, including form of presentation, in-hospital treatment and in-hospital complications, according to gender and in three different periods. METHODS: We performed an observational study with retrospective analysis of all patients included between 2002 and 2019 in the Portuguese Registry of Acute Coronary Syndromes (ProACS), a voluntary, observational, prospective, continuous registry of the Portuguese Society of Cardiology and the National Center for Data Collection in Cardiology. RESULTS: A total of 49 113 patients (34 936 men and 14 177 women) were included. Obesity, hypertension, diabetes (p<0.001 for all) and dyslipidemia (p=0.022) were all more prevalent in women, who were more frequently admitted for non-ST segment elevation ACS (p<0.001), and more frequently presented with atypical symptoms. Women had more time until needle and until reperfusion, which is less accessible to this gender (p<0.001). During hospitalization, women had a significantly higher risk of in-hospital mortality (OR 1.94 [1.78-2.12], p<0.001), major bleeding (OR 1.53 [1.30-1.80], p<0.001), heart failure (OR 1.87 [1.78-1.97], p<0.001), atrial fibrillation (OR 1.55 [1.36-1.77], p<0.001), mechanical complications (OR 2.12 [1.78-2.53], p<0.001), cardiogenic shock (OR 1.71 [1.57-1.87], p<0.001) and stroke (OR 2.15 [1.76-2.62], p<0.001). Women were more likely to have a normal coronary angiogram or coronary lesions with <50% luminal stenosis (p<0.001 for both), and thus a final diagnosis other than ACS. Both during hospitalization and at hospital discharge, women were less likely to receive guideline-recommended secondary prevention therapy. CONCLUSION: In women admitted for ACS, revascularization strategies are still underused, as is guideline-recommended secondary prevention therapy, which may explain their higher incidence of in-hospital complications and higher unadjusted mortality.

A patient with a dual chamber pacemaker was admitted to the emergency room after out-of-hospital cardioversion for syncopal sustained monomorphic ventricular tachycardia. Device interrogation revealed an abnormally timed ventricular spike after a ventricular premature beat at the beginning of the event, caused by a pacemaker algorithm designed to avoid atrial fibrillation, non-competitive atrial pacing. Despite the absence of significant coronary lesions, in the setting of a vulnerable substrate - a hypokinetic and hyperechogenic region of ventricular myocardium - an upgrade to a dual-chamber implantable cardioverter-defibrillator was performed, and substrate ablation was planned.

The authors describe a case of a patient admitted with a pre-syncopal episode and precordial discomfort, and whose cardiac ultrasound performed in the Emergency Room was suggestive of Pulmonary Embolism. The patient was submitted to fibrinolytic therapy after cardiac arrest. The computerized tomography done after this episode not only confirmed the presence of pulmonary embolism but had also shown a Stanford Type B Aortic Dissection. The option was to maintain the therapeutic anticoagulation, having the patient evolved favourably.

OBJECTIVE: To evaluate the impact of a real-time visual feedback device on Chest comparison (CCs) rate and depth delivered by healthcare professionals. METHODS: In a simulated scenario a sensor was placed on a manikin's chest and connected to a defibrillator which provided real-time visual feedback on the rate and depth of CCs. Thirty-two healthcare professionals performed sequentially 5 cycles of 30 CCs without (FeedOFF) and with (FeedON) feedback. CCs with a depth between 50 and 60mm and a rate between 100 and 120cpm were considered optimal. RESULTS: Visual feedback resulted in a significant increase in the proportion of CCs with optimal depth (median 8.7 [interquartile range 0.7-55.5]% FeedOFF vs 63.3 [17.6-88.1]% FeedON, p=0.002) and optimal rate (median 51.3 [1.3 - 81.3]% FeedOFF vs 68.3 [45.3 - 86.1]% FeedON, p=0.018). Overall, CCs were too shallow and too fast in the FeedOFF cycle. There was also a significant increase in optimal CCs (optimal depth and rate) with the use of the feedback device (from median 0.7 [0 - 26.9]% FeedOFF to 31.9 [3.6-59.9]% FeedON, p=0.001). Participants' factors such as age, sex, body mass index, job or time since last CPR training did not have a significant impact on CPR quality. CONCLUSIONS: In the absence of visual feedback, there is a tendency towards lower depth and higher rate of CCs. The use of feedback technology significantly improves the quality of CCs.
