Cardiovascular risk assessment in Portugal's primary health care system: SCORE vs. SCORE2.

INTRODUCTION AND OBJECTIVES: The 2021 European Society of Cardiology guidelines on cardiovascular disease (CVD) prevention introduced the more accurate SCORE2 risk model as a replacement for the earlier SCORE, which is still used in primary care software in Portugal. Our objective is to determine whether the difference between risk assessment using SCORE and SCORE2, in the same patient population, is statistically significant. METHODS: A total of 1642 patients aged 40-65 without previous CVD, from the medical records of two Family Health Units, were included in this cross-sectional study. SCORE and SCORE2 were calculated using the variables gender, age, smoking status, lipid profile and systolic blood pressure. A statistical analysis was performed on the results. RESULTS: Using SCORE, 98% of the patients were in the low-moderate risk categories and 2% in the high or very high risk categories. When using SCORE2, the corresponding percentages were 55% and 45%, respectively. Reclassification with SCORE2 into higher categories was more often observed in younger (under 50 years of age) and male patients. With SCORE, 38.61% of patients were within the LDL-C target range; this figure fell to 20.28% with SCORE2. These differences are statistically significant (p<0.0001). CONCLUSION: Our findings show that a significant number of patients in this cohort who were classified through SCORE at lower risk levels were reclassified into higher risk categories with SCORE2. Similarly, the number of patients within the LDL-C target range for LDL-C was also lower using SCORE2.

PrOgnosis in Pulmonary Embolism (PoPE): 30-Day mortality risk score based on five admission parameters.

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.

Underuse of reperfusion therapy with systemic thrombolysis in high-risk acute pulmonary embolism in a Portuguese center.

INTRODUCTION: Reperfusion therapy is generally recommended in acute high-risk pulmonary embolism (HR-PE), but several population-based studies report that it is underused. Data on epidemiology, management and outcomes of HR-PE in Portugal are scarce. OBJECTIVE: To determine the reperfusion rate in HR-PE patients, the reasons for non-reperfusion, and how it influences outcomes. METHODS: In this retrospective cohort study of consecutive HR-PE patients admitted to a thromboembolic disease referral center between 2008 and 2018, independent predictors for non-reperfusion were assessed by multivariate logistic regression. PE-related mortality and long-term MACE (cardiovascular mortality, PE recurrence and chronic thromboembolic disease) were calculated according to the Kaplan-Meier method. Differences stratified by reperfusion were assessed using the log-rank test. RESULTS: Of 1955 acute PE patients, 3.8% presented with hemodynamic instability. The overall reperfusion rate was 50%: 35 patients underwent systemic thrombolysis, one received first-line percutaneous embolectomy and one rescue endovascular treatment. Independent predictors of non-reperfusion were: age, with >75 years representing 12 times the risk of non-treatment (OR 11.9, 95% CI 2.7-52.3, p=0.001); absolute contraindication for thrombolysis (31.1%), with recent major surgery and central nervous system disease as the most common reasons (OR 16.7, 95% CI 3.2-87.0, p<0.001); and being hospitalized (OR 7.7, 95% CI 1.4-42.9, p=0.020). At a mean follow-up of 2.5±3.3 years, the survival rate was 33.8%. Although not reaching statistical significance for hospital mortality, mortality in the reperfusion group was significantly lower at 30 days, 12 months and during follow-up (relative risk reduction of death of 64% at 12 months, p=0.013). Similar results were found for MACE. CONCLUSIONS: In this population, the recommended reperfusion therapy was performed in only 50% of patients, with advanced age and absolute contraindications to fibrinolysis being the main predictors of non-reperfusion. In this study, thrombolysis underuse was associated with a significant increase in short- and long-term mortality and events.

Investigation of the effect of intravitreal bevacizumab treatment on left heart function using speckle tracking echocardiography.

INTRODUCTION AND OBJECTIVES: Vascular endothelial growth factor (VEGF) inhibitors are widely used in oncology and ophthalmology. Although these agents have been shown to increase the risk of cardiovascular events in systemic use, the effect of local applications is unclear. In our study, we aimed to investigate the effects of anti-VEGF agents on left heart functions after intravitreal injection using speckle tracking echocardiography. METHODS: In this prospectively designed study, 44 patients who were going to start intravitreal anti-VEGF treatment were included in the study. Patients were evaluated with speckle tracking echocardiography before the first anti-VEGF administration and at three months of anti-VEGF treatment. RESULTS: Global longitudinal strain (GLS) values at three months were lower in the patients who participated in the study and this was statistically significant (-18.77±2.17, -18.60±2.01, p=0.001). Also, there was a statistically significant decrease in the mean values of GLS (GLS4CH) obtained from apical four space image, GLS (GLSAPLAX) obtained from apical long axis image and GLS (GLS2CH) obtained from apical 2 space image at month 0 and month 3 (-19.08±2.39, -18.93±2.26, p=0.004; -18.81±2.29, -18.60±2.12, p=0.001; -18.44±2.31, -18.27±2.12, p=0.013, respectively). CONCLUSION: The slight decrease in GLS in our study suggests that the use of intravitreal anti-VEGF agents may have cardiac effects.

World Heart Federation Cholesterol Roadmap: The Portuguese case.

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.

Validation of the SCORE2 risk prediction algorithm in a Portuguese population: A new model to estimate 10-year cardiovascular disease incidence in Europe.

INTRODUCTION AND OBJECTIVES: Subjects without cardiovascular (CV) disease (CVD) may suffer from subclinical atherosclerosis, and are at increased risk for atherosclerotic CV events (ASCVE). The ESC/EAS risk SCORE was updated by SCORE2, which estimates 10-year risk of fatal and non-fatal CVD in European populations aged 40-69 years without established CVD or diabetes. Our aim was to compare the two ESC/EAS risk scores and to validate SCORE2 in our population. METHODS: A total of 1071 individuals (age 57.2±6.1 years; 75.2% male) without CVD or diabetes, from GENEMACOR study controls, were analyzed over 5.4±3.9 years. The population was stratified into risk categories according to the two scores, and the area under the ROC curve (AUC) and Harrell's C-index assessed the scores' performance. Calibration was performed using the goodness-of-fit test, and occurrence of the first event assessed by Cox regression. Kaplan-Meier analysis estimated SCORE2 survival. RESULTS: SCORE stratified subjects into four risk categories: low (7.4%), moderate (46.5%), high (25.3%) and very high (20.8%), and SCORE2 into three: low-to-moderate (24.7%), high (59.0%) and very high (16.2%). SCORE presented good discrimination for CV mortality (AUC=0.838; C-index=0.834, 95% CI: 0.728-0.940), as did SCORE2 for total CV events (AUC=0.744; C-index=0.728, 95% CI: 0.648-0.808). Calibration did not show a disparity between observed and expected ASCVE. The probability of ASCVE was eight times higher in very-high-risk SCORE2 (p=0.001), and three times in the high-risk group (p=0.049). Event-free survival was 99%, 90% and 72% in the low-to-moderate, high and very-high-risk categories, respectively (p<0.0001). CONCLUSIONS: SCORE2 improved population stratification by identifying higher-risk patients, enabling early preventive measures. It showed good discriminative ability for all ASCVE.

Clinical features and long-term outcomes in patients under 35 years with coronary artery disease: Nested case-control study.

INTRODUCTION AND OBJECTIVES: Coronary artery disease (CAD) is a globally significant cardiovascular condition, ranking among the leading causes of morbidity and mortality. CAD has been predominantly associated with advanced age and classic cardiovascular risk factors. However, over the past decades, there has been a concerning rise in its occurrence among young adults, including patients under 35 years old. The present study analyzes the clinical features and outcomes of patients aged ≤35 years with CAD, compared to two age-matched control groups. METHOD: A nested case-control study of ≤35-year-old patients referred for coronary angiography due to clinical suspicion of CAD. Patients were divided into three groups: patients ≤35 years with CAD, subjects ≤35 years without CAD, and young patients ≥36-40 years with CAD. RESULTS: Of the 19321 coronary angiographies performed at our center over 10 years, 408 (2.1%) patients were ≤40 years old, 109 patients aged ≤35 years. Risk factors that showed a relationship with the presence of CAD were smoking (OR 2.49; 95% CI 1.03-6.03; p=0.042) and family history of coronary disease (OR 6.70; 95% CI 1.46-30.65; p=0.014). The group aged ≤35 years with CAD exhibited a risk of major cardiovascular adverse events (MACE) (HR 13.3; 95% CI 1.75-100; p<0.001) than subjects ≤35 years without CAD. The probability of major adverse cardiovascular events was associated with being ≤35 years old, diabetes, dyslipidemia, and depression. CONCLUSION: Patients aged ≤35 exhibited a poor long-term prognosis, with a high risk of new revascularization and acute myocardial infarction during the follow-up period. Focusing on preventive measures can have a significant impact on overall prognosis.

Coronary atherosclerotic burden in veteran athletes: The relationship between cardiovascular risk and volume of exercise.

INTRODUCTION AND OBJECTIVES: The association between exercise and coronary atherosclerosis still remains unclarified. We aimed to analyze the prevalence of high coronary atherosclerotic burden in veteran athletes, considering cardiovascular (CV) risk and volume of exercise. METHODS: A total of 105 asymptomatic male veteran athletes (48±5.6 years old) were studied. A high coronary atherosclerotic burden was defined as one of the following characteristics in coronary computed tomography angiography: calcium score >100, >75th percentile, obstructive plaques, involving left main, three-vessels or two-vessels including proximal anterior descending artery, segment involvement score >5 or CT-adapted Leaman score ≥5. CV risk was stratified by SCORE2 and volume of exercise by metabolic equivalent task score. RESULTS: Most athletes (n=88) were engaged in endurance sports for 17.1±9.8 years, with a median exercise volume of 66 [IQR 44-103] metabolic equivalent of tasks/hour/week. The mean Systematic Coronary Risk Evaluation 2 was 2.8±1.5%; 76.9% of athletes had a low-moderate risk and none a very high risk. High coronary atherosclerotic burden was present in 25.7% athletes. Athletes with high cardiovascular risk and high exercise volume (above the median) showed significantly high coronary atherosclerotic burden compared to those with low-moderate risk and high volume (50.0% vs. 15.6%; p=0.017). Among athletes with low to moderate risk, a high volume of exercise tended to be protective, while in those with low volume, there was similar rate of high coronary atherosclerotic burden, regardless of CV risk. CONCLUSIONS: A combination of higher volume of exercise and high cardiovascular risk revealed the worst association with coronary atherosclerosis in veteran athletes. The relationship between these variables is controversial, but integrating exercise characteristics and risk assessment into preparticipation evaluation is essential.

Defining the Limits of Acceptable Parenthood: Reproductive Governance in Brazil.

Drawing on sources relating to the Brazilian scenario - from ethnographic research in lower-income neighorhoods to the analysis of official documents and public debates - we build on cases of forced child removals to explore the intersectional dynamics of class, race, and gender that underlie institutionalized practices of discrimination against poverty-stricken families. After first addressing the influence of recent global trends in child-protection policy, we observe how adoption procedures in Brazil have been increasingly facilitated by the resignification of rights and corresponding changes in the country's legal infrastructures. Next, asking what sort of authoritative knowledge is invoked to define a child's best interests, we reflect on the role played by biomedicine in appraising the limits of acceptable parenthood. Guided by the notion of stratified reproduction, our investigation of these political, scientific, and moral technologies suggests plausible connections between policies that condition the demand for and the supply of adoptable children.

Cardiovascular risk assessment using SCORE2 in a population with hypertension - The reality at a primary health care unit.

INTRODUCTION AND OBJECTIVES: Cardiovascular disease (CVD) is the leading cause of morbidity and mortality in Portugal, thus it is important to identify individuals at risk. Patients with hypertension have an increased risk of adverse cardiovascular (CV) events. The role of LDL cholesterol (LDL-C) in atherosclerotic CVD is well-established. SCORE2, a new CV risk calculation tool, is used to predict the 10-year risk of fatal or non-fatal CVD. The aim of this study was to understand the impact of SCORE2 on CV risk assessment in a population with hypertension from a moderate risk country, compared to the previously used SCORE. METHODS: This observational cross-sectional study analyzed a population census of 3146 patients diagnosed with hypertension without complications (K86). After applying inclusion and exclusion criteria, 654 patients were included. Data from medical records were collected to calculate and compare SCORE and SCORE2 categories and LDL-C targets. RESULTS: Patients were classified into SCORE categories: 188 (28.75%) low, 448 (68.5%) moderate, 17 (2.6%) high and 1 (0.15%) very high risk. Using SCORE2, individuals in the SCORE low risk category were reclassified, requiring new targets: 149 individuals (80%) as low to moderate and 39 (20%) as high risk. These differences became more evident when considering SCORE moderate and high-risk categories, where 358 patients (77%) received a higher CV risk categorization, and therefore a lower LDL-C target. There was a significant increase in individuals failing to meet the target when using SCORE2, compared to SCORE (p<0.001). CONCLUSION: These findings support the importance of CV risk assessment using SCORE2 algorithm in patients with hypertension.

Pulmonary arterial hypertension: Navigating the pathways of progress in diagnosis, treatment, and patient care.

Pulmonary arterial hypertension (PAH) is a form of precapillary pulmonary hypertension caused by a complex process of endothelial dysfunction and vascular remodeling. If left untreated, this progressive disease presents with symptoms of incapacitating fatigue causing marked loss of quality of life, eventually culminating in right ventricular failure and death. Patient management is complex and based on accurate diagnosis, risk stratification, and treatment initiation, with close monitoring of response and disease progression. Understanding the underlying pathophysiology has enabled the development of multiple drugs directed at different targets in the pathological chain. Vasodilator therapy has been the mainstay approach for the last few years, significantly improving quality of life, functional status, and survival. Recent advances in therapies targeting dysfunctional pathways beyond endothelial dysfunction may address the fundamental processes underlying the disease, raising the prospect of increasingly effective options for this high-risk group of patients with a historically poor prognosis.

Impact of genetic information on coronary disease risk in Madeira: The GENEMACOR study.

INTRODUCTION: Coronary artery disease (CAD), characterized by an atherogenic process in the coronary arteries, is one of the leading causes of death in Madeira. The GENEMACOR (GENEs in MAdeira and CORonary Disease) study sought to investigate the main risk factors - environmental and genetic - and estimate whether a genetic risk score (GRS) improves CAD prediction, discrimination and reclassification. METHODS: Traditional risk factors and 33 CAD genetic variants were considered in a case-control study with 3139 individuals (1723 patients and 1416 controls). The multivariate analysis assessed the likelihood of CAD. A multiplicative GRS (mGRS) was created, and two models (with and without mGRS) were prepared. Two areas under receiver operating characteristic curve (area under curve (AUC)) were analyzed and compared to discriminate CAD likelihood. Net reclassification improvement (NRI) and integrated discrimination index (IDI) were used to reclassify the population. RESULTS: All traditional risk factors were strong and independent predictors of CAD, with smoking being the most significant (OR 3.25; p<0.0001). LPA rs3798220 showed a higher CAD likelihood (odds ratio 1.45; p<0.0001). Individuals in the fourth mGRS quartile had an increased CAD probability of 136% (p<0.0001). A traditional risk factor-based model estimated an AUC of 0.73, rising to 0.75 after mGRS inclusion (p<0.0001), revealing a better fit. Continuous NRI better reclassified 28.1% of the population, and categorical NRI mainly improved the reclassification of the intermediate risk group. CONCLUSIONS: CAD likelihood was influenced by traditional risk factors and genetic variants. Incorporating GRS into the traditional model improved CAD predictive capacity, discrimination and reclassification. These approaches may provide helpful diagnostic and therapeutic advances, especially in the intermediate risk group.

Transcription factor 21 gene and prognosis in a coronary population.

INTRODUCTION AND OBJECTIVES: Transcription factor 21 (TCF21) is a member of the basic helix-loop-helix (bHLH) transcription factor family, and is critical for embryogenesis of the heart. It regulates differentiation of epicardium-derived cells into smooth muscle cell (SMC) and fibroblast lineages. The biological role of TCF21 in the progression of atherosclerosis is the subject of debate. The aim of this study was to investigate the impact of the TCF21 rs12190287 gene variant on the prognosis of coronary artery disease (CAD) in a Portuguese population from Madeira island. METHODS: We analyzed major adverse cardiovascular events (MACE) in 1713 CAD patients, mean age 53.3±7.8, 78.7% male, for 5.0±4.3 years. Genotype and allele distribution between groups with and without MACE was determined. The dominant genetic model (heterozygous GC plus homozygous CC) was used and compared with the wild GG to assess survival probability. Cox regression with risk factors and genetic models assessed variables associated with MACE. Kaplan-Meier analysis was used to estimate survival. RESULTS: The wild homozygous GG, heterozygous GC and risk CC genotypes were found in 9.5%, 43.2% and 47.3% of the population, respectively. The dominant genetic model remained in the equation as an independent risk factor for MACE (HR 1.41; p=0.033), together with multivessel disease, chronic kidney disease, low physical activity and type 2 diabetes. The C allele in the dominant genetic model showed worse survival (22.5% vs. 44.3%) at 15 years of follow-up. CONCLUSION: The TCF21 rs12190287 variant is a risk factor for CAD events. This gene may influence fundamental SMC processes in response to vascular stress, accelerating atherosclerosis progression, and may represent a target for future therapies.

High prevalence of cardiovascular disease and risk factors among type 2 diabetes patients followed in a hospital setting in Portugal: The PICT2RE observational study.

INTRODUCTION AND OBJECTIVES: Portugal is a country with a high prevalence of type 2 diabetes (T2D) and cardiovascular disease (CVD). The prevalence of CVD and cardiovascular (CV) risk factors among T2D patients followed in hospitals in Portugal is not known. The primary objective of this study was to assess the prevalence of CVD and CV risk factors among T2D patients in a hospital setting in Portugal. The clinical management of CVD in the hospital setting was also assessed. METHODS: We performed a non-interventional, multicenter, cross-sectional study with a retrospective phase. T2D patients were consecutively invited to participate. Data were collected retrospectively. RESULTS: A total of 715 patients were included in the study. Mean age and diabetes duration were 66.6 and 17.4 years, respectively. Of these, 286 patients (40.0%) had been diagnosed with CVD, mostly ischemic heart disease (50.4%). All patients had at least one CV risk factor. CVD was significantly associated with hypertension, hypercholesterolemia, low high-density lipoprotein cholesterol, hypertriglyceridemia and smoking. During the three years prior to study inclusion, the incidence of hyperglycemic episodes and T2D complications increased among patients with established CVD, but the numbers of hospitalization episodes and specialist appointments remained stable. An improvement was observed in key cardiometabolic risk factors. CONCLUSIONS: Our study revealed a high prevalence of CVD and CV risk factors among a sample of T2D patients in a hospital setting. Patients with established CVD seem to be adequately managed but further efforts are needed at the prevention stage for better control of risk factors and morbidity.

Clinical outcomes in heart failure with reduced left ventricular ejection fraction and good functional capacity: The illusion of stability.

BACKGROUND: Heart failure (HF) remains a prevalent syndrome with significant morbidity and mortality. Optimal drug and device therapies are crucial to reduce the risk of death or HF admission. Yet, less symptomatic patients with good functional capacity are often perceived as having a low risk of adverse events and their attending physicians may suffer from prescription inertia or refrain from performing therapy optimization. Maximum or peak oxygen consumption (pVO2) assessed during cardiopulmonary exercise testing (CPET) is often used as a prognosis indicator and surrogate marker for functional capacity. Our goal was to assess clinical outcomes in a seemingly low risk HF population in Weber class A (pVO2>20 mL/kg/min) with reduced left ventricular ejection fraction (LVEF). METHODS: Single-center retrospective observational study enrolling consecutive HF patients with LVEF<40% (HFrEF) performing CPET between 2003 and 2018. Those with pVO2 >20 mL/kg/min were included. The primary endpoint was a composite of all-cause death or HF hospitalizations at two years after CPET. We also assessed the rates of N-terminal pro b-type natriuretic peptide (NT-proBNP) elevations at baseline. RESULTS: Seventy-two patients were included (mean age of 53±10 years; 86% male; 90% NYHA I-II; median LVEF 32%; median pVO2 24 mL/kg/min). At baseline, 93% had an NT-proBNP level >125 pg/mL (median NT-proBNP 388 [201-684] pg/mL). Overall, seven patients (10%) met the primary endpoint: three died (4%) and five (7%) had at least one HF admission. Among those who died, only one patient had an HF admission during follow up. CONCLUSION: In a clinically stable HFrEF population with good functional capacity, persistent neurohormonal activation was present in the majority, and one in ten patients died or had a HF admission at two years' follow-up. These findings support the urgent need to motivate clinicians to pursue optimal drug uptitration even in less symptomatic patients.

Adherence to European guidelines for the use of aspirin in primary health care.

INTRODUCTION AND OBJECTIVES: Cardiovascular disease remains a leading cause of global morbidity and mortality. The administration of low doses of aspirin in secondary prevention of atherosclerotic cardiovascular disease (ASCVD) has been clearly established. However, the most recent guidelines do not recommend aspirin in primary prevention, reserving it for high-risk patients and after a risk/benefit assessment. The aim of this study was to assess adherence to European guidelines for the use of aspirin in primary and secondary prevention of ASCVD in primary health care. METHODS: The study population consisted of individuals aged >50 years registered at two primary health care units without (primary prevention) and with previous ASCVD events (secondary prevention). RESULTS: We studied a total of 1262 individuals, 720 in primary prevention and 542 in secondary prevention. A total of 61 individuals (8.5%) were under aspirin therapy in primary prevention, most of them taking 150 mg/day (57%). In secondary prevention, 195 patients (27%) were receiving aspirin only, most taking 150 mg/day (52%), and 166 patients (31%) were not under any antithrombotic or anticoagulant therapy. The 100 mg dosage was predominant in patients with ischemic heart disease with (64%) and without (64%) angina, as well as those with myocardial infarction (61.5%) and peripheral vascular disease (62%). CONCLUSIONS: In this study, the prevalence of aspirin use in primary prevention was 8.5%. We found that 30% of patients were not taking either antithrombotic or anticoagulation therapy in secondary prevention. In both primary and secondary prevention, the 150 mg dosage was predominant.

The MAGGIC risk score in the prediction of death or hospitalization in patients with heart failure: Comparison with natriuretic peptides.

BACKGROUND: The MAGGIC risk score has been validated to predict mortality in patients with heart failure (HF). OBJECTIVES: To assess the score ability to predict hospitalization and death and to compare with natriuretic peptides. METHODS: Ninety-three consecutive patients (mean age 62±10 years) with chronic HF and left ventricular ejection fraction (EF) <50% were studied. The MAGGIC score was applied at baseline and the patients were followed for 219±86 days. MAGGIC score was compared with NT-proBNP in the prediction of events. The primary end point was the time to the first event, which was defined as cardiovascular death or hospitalization for HF. RESULTS: There were 23 (24.7%) events (3 deaths and 20 hospitalizations). The median score in patients with and without events was, respectively, 20 [interquartile range 14.2-22] vs. 15.5 [11/21], p=0.16. A ROC curve was performed and a cutoff point of 12 points showed a sensitivity of 87% and specificity of 37% with an area under the curve of 0.59 (95% CI 0.48-0.69) which was lower than that of NT-proBNP (AUC 0.67; 95% CI 0.56-0.76). The mean event-free survival time for patients above and below this cutpoint was 248.8±13 vs. 290±13.7 days (log rank test with p=0.044). Using the COX proportional hazard model, age (p=0.004), NT-proBNP >1000 pg/mL (p=0.014) and the MAGGIC score (p=0.025) were independently associated with the primary outcome. CONCLUSION: The MAGGIC risk score was an independent predictor of events, including heart failure hospitalization. The addition of biomarkers improved the accuracy of the score.

Management of dyslipidemia in diabetic patients: The situation in primary health care units.

INTRODUCTION: Cardiovascular disease is one of the main causes of morbidity and mortality worldwide. Control of its risk factors, particularly diabetes and dyslipidemia, through reduction of LDL cholesterol, is crucial to reduce cardiovascular risk. This work aims to assess and improve the medical approach to dyslipidemia in diabetic patients. METHODS: This is a quality improvement study aimed at family doctors. It included patients with diabetics and dyslipidemia enrolled in the primary health care units of Além D'Ouro, S. Miguel and Oceanos. A quality standard was defined for each of the criteria assessed, and the results were compared using the chi-square test with p-value<0.05. Data analysis was performed using Microsoft Excel 2010® and IBM SPSS®. RESULTS: Comparing the first and second assessments, 14.6% vs. 22.2% (p=0.016) of the patients, respectively, achieved the LDL cholesterol target level of <70 mg/dl. Of those who did not meet the target level, 11.0% vs. 13.6% (p=0.395) had their pharmacological therapy changed and 4.6% vs. 3.3% (p=0.448) had their lipid profile reassessed within three months. CONCLUSIONS: Control of dyslipidemia in patients with diabetes continues to be a major factor in the health of these patients, but it is carried out in an unsatisfactory way in the three health units studied. It is essential to increase the literacy of family doctors and to encourage the search for the best possible lipid control, in order to reduce cardiovascular risk, as well as to raise awareness among patients to increase adherence to therapy.

Long-term outcomes of primary cardiovascular prevention: A retrospective study at a referral center in Portugal.

INTRODUCTION AND OBJECTIVES: Lifestyle changes are frequently insufficient to reduce cardiovascular (CV) risk in patients with dyslipidemia. This study aims to characterize the long-term evolution of lipid profile and CV risk of patients under primary prevention. METHODS: A retrospective study was performed of outpatients at a Portuguese cardiovascular risk clinic with ≥2 CV risk factors, followed for ≥2 years between 1995 and 2015. Statin therapy had been initiated early, in accordance with the clinic's practice. After written informed consent was obtained, sociodemographic and clinical characteristics were collected from medical charts, at baseline and last visit. Changes in lipid profile and CV risk scores were estimated. Associations between HDL-C or LDL-C changes and gender, age, observation time and treatments were assessed through bivariate analysis and multiple linear regression models. RESULTS: Out of 516 participants with mean follow-up of 11.4±4.3 years, 56.6% were female and 91.5% received statins. Lipid profile showed statistically significant improvement, including median changes in LDL-C and HDL-C of -77.0 mg/dl and +19 mg/dl, respectively. CV risk also showed statistically significant improvements according to all scores. Statin therapy resulted in a mean HDL-C increase of 7.4 mg/dl (independently of gender and other treatments) and a mean LDL-C reduction of 51.8 mg/dl (irrespective of age and other treatments). CONCLUSION: Results from this long-term real-life study indicate that primary prevention, specifically early and continuous therapy with intermediate-intensity statins as an add-on to lifestyle interventions, was important in obtaining consistent and adequate metabolic correction in patients with additional risk factors.
