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.

Atherosclerotic cardiovascular disease (ASCVD) remains the major cause of premature death and disability; effective cardiovascular (CV) risk prevention is fundamental. The World Heart Federation (WHF) Cholesterol Roadmap provides a framework for national policy development and aims to achieve ASCVD prevention. At the invitation of the WHF, a group of experts from the Portuguese Society of Cardiology (SPC), addressed the cholesterol burden at nationally and discussed possible strategies to include in a Portuguese cholesterol roadmap. The literature review showed that the cholesterol burden in Portugal is high and especially uncontrolled in those with the highest CV risk. An infographic scorecard was built to include in the WHF collection, for a clear idea about CV risk and cholesterol burden in Portugal, which would also be useful for health policy advocacy. The expert discussion and preventive strategies proposal followed the five pillars of the WHF document: awareness improvement; population-based approaches for CV risk and cholesterol; risk assessment/population screening; system-level approaches; surveillance of cholesterol and ASCVD outcomes. These strategies were debated by all the expert participants, with the goal of creating a national cholesterol roadmap to be used for advocacy and as a guide for CV prevention. Several key recommendations were outlined: include all stakeholders in a multidisciplinary national program; create a structured activities plan to increase awareness in the population; improve the quality of continuous CV health education; increase the interaction between different health professionals and non-health professionals; increment the referral of patients to cardiac rehabilitation; screen cholesterol levels in the general population, especially high-risk groups; promote patient self-care, engage with patients' associations; use specific social networks to spread information widely; create a national database of cholesterol levels with systematic registry of CV events; redefine strategies based on the evaluation of results; create and involve more patients' associations - invert the pyramid order. In conclusion, ASCVD and the cholesterol burden remain a strong global issue in Portugal, requiring the involvement of multiple stakeholders in prevention. The Portuguese cholesterol roadmap can provide some solutions to help urgently mitigate the problem. Population-based approaches to improve awareness and CV risk assessment and surveillance of cholesterol and ASCVD outcomes are key factors in this change. A call to action is clearly needed to fight hypercholesterolemia and ASCVD burden.
RESUMO
Global warming is a result of the increased emission of greenhouse gases. The consequences of this climate change threaten society, biodiversity, food and resource availability. The consequences include an increased risk of cardiovascular (CV) disease and cardiovascular mortality. In this position paper, we summarize the data from the main studies that assess the risks of a temperature increase or heat waves in CV events (CV mortality, myocardial infarction, heart failure, stroke, and CV hospitalizations), as well as the data concerning air pollution as an enhancer of temperature-related CV risks. The data currently support global warming/heat waves (extreme temperatures) as cardiovascular threats. Achieving neutrality in emissions to prevent global warming is essential and it is likely to have an effect in the global health, including the cardiovascular health. Simultaneously, urgent steps are required to adapt the society and individuals to this new climatic context that is potentially harmful for cardiovascular health. Multidisciplinary teams should plan and intervene healthcare related to temperature changes and heat waves and advocate for a change in environmental health policy.

Air pollution is one of the main environmental risk factors for health and is linked to cardiovascular diseases, which are the leading cause of mortality worldwide. In this position paper, we discuss the main air pollutants and how they can promote the development of cardiovascular disease or cardiovascular events. We also summarise the main evidence supporting the association between air pollution and cardiovascular events, such as coronary events (acute coronary syndromes/myocardial infarction; chronic coronary syndromes), stroke, heart failure and mortality. Some recommendations are made based on these data and the European Society of Cardiology guidelines on cardiovascular disease prevention, acknowledging that it is important to increase awareness and literacy on this topic in Portugal.
RESUMO
INTRODUCTION AND OBJECTIVES: The role of endothelial dysfunction (ED) in patients with ST-elevation myocardial infarction (STEMI) is poorly understood. Peripheral arterial tonometry (PAT) allows non-invasive evaluation of ED, but has never been used for this purpose early after primary percutaneous coronary intervention (P-PCI). Our purpose was to analyze the relation between ED assessed by PAT and both the presence of microvascular obstruction (MVO) and infarct extension in STEMI patients. METHODS: ED was assessed by the reactive hyperemia index (RHI), measured by PAT and defined as RHI <1.67. Infarct extension was assessed by troponin I (TnI) release and contrast-enhanced cardiac magnetic resonance (ceCMR). MVO was assessed by ceCMR and by indirect angiographic and ECG indicators. An echocardiogram was also performed in the first 12 h. RESULTS: We included 38 patients (mean age 60.0±13.7 years, 29 male). Mean RHI was 1.87±0.60 and 16 patients (42.1%) had ED. Peak TnI (median 118 mg/dl, IQR 186 vs. 67/81, p=0.024) and AUC of TnI (median 2305, IQR 2486 vs. 1076/1042, p=0.012) were significantly higher in patients with ED, who also showed a trend for more transmural infarcts (63.6% vs. 22.2%, p=0.06) and larger infarct mass on ceCMR (median 17.5%, IQR 15.4 vs. 10.1/10.3, p=0.08). Left ventricular ejection fraction (LVEF) was lower and wall motion score index (WMSI) was higher on both echocardiogram and ceCMR in patients with ED. On ceCMR, MVO was more frequent in patients with RHI <1.67 (54.5% vs. 11.1%, p=0.03). ECG and angiographic indicators of MVO all showed a trend toward worse results in these patients. CONCLUSIONS: The presence of ED assessed by PAT 24 h after P-PCI in patients with STEMI is associated with larger infarcts, lower LVEF, higher WMSI and higher prevalence of MVO.
