Cardiovascular diseases in women - Consensus document of the Sociedade Portuguesa de Cardiologia, Sociedade Portuguesa de Ginecologia, Sociedade Portuguesa de Obstetrícia e Medicina Materno-Fetal, Sociedade Portuguesa de Contraceção e Associação Portuguesa de Medicina Geral e Familiar. / Saúde cardiovascular da mulher ­ Documento de Consenso da Sociedade Portuguesa de Cardiologia, Sociedade Portuguesa de Ginecologia, Sociedade Portuguesa de Obstetrícia e Medicina Materno­Fetal, Sociedade Portuguesa de Contraceção e Associação Portuguesa de Medicina Geral e Familiar.

The main objective of this consensus statement from the Portuguese Society of Cardiology, the Portuguese Society of Gynecology, the Portuguese Society of Obstetrics and Maternal-Fetal Medicine, Portuguese Society of Contraception, Portuguese Association of General Practice and Family Medicine is to improve cardiovascular care for women. It includes a brief review of the state-of-the-art of cardiovascular diseases in women and of the links to other fields such as Gynaecology, Obstetrics and Endocrinology. It also provides final recommendations to help clinicians working in care of women's health.

Consensus document on chronic coronary syndrome assessment and risk stratification in Portugal: A position paper statement from the [Portuguese Society of Cardiology's] Working Groups on Nuclear Cardiology, Magnetic Resonance and Cardiac Computed Tomography, Echocardiography, and Exercise Physiology and Cardiac Rehabilitation. / Documento de Consenso sobre Estratificação de Risco Cardiovascular e estudo da doença coronária em Portugal: a posição dos Grupos de Estudo de Cardiologia Nuclear, Ressonância Magnética e Tomografia Computorizada Cardíaca, de Ecocardiografia e de Fisiopatologia do Esforço e Reabilitação Cardíaca.

Despite constant medical evolution, the reimbursement policy of Portuguese National Health Service (NHS) for the study and risk stratification of coronary heart disease has remained unchanged for several decades. Lack of adjustment to contemporary clinical practice has long been evident. However, the recent publication of the European Guidelines for diagnosis and treatment of chronic coronary syndromes further highlighted this gap and the urgent need for a change. Prompted by these Guidelines, the Working Group on Nuclear Cardiology, Cardiac Magnetic Resonance and Cardiac CT, the Working Group on Echocardiography and the Working Group on Stress Pathophysiology and Cardiac Rehabilitation of the Portuguese Society of Cardiology, began a process of joint reflection on the current limitations and how these recommendations could be applied in Portugal. To this end, the authors suggest that the new imaging methods (stress echocardiogram, cardiac computed tomography and cardiac magnetic resonance), should be added to exercise treadmill stress test and myocardial perfusion scintigraphy in the available exam portfolio within the Portuguese NHS. This change would allow full adoption of European guidelines and a better use of tests, according to clinical context, availability and local specificities. The adoption of clinical guidance standards, based on these assumptions, would translate into a qualitative improvement in the management of these patients and would promote an effective use of the available resources, with potential health and financial gains.

[Biomarkers of functional class in systolic heart failure: the relevance of copeptin]. / Biomarcadores da classe funcional na insuficiência cardíaca sistólica. Relevância da copeptina.

INTRODUCTION: Functional class is an important predictor of prognosis in chronic heart failure (CHF). However, it is often subjective and poorly reproducible. OBJECTIVE: We sought to identify diagnostic markers of high functional class. METHODS: We prospectively studied 37 patients with symptomatic CHF and ejection fraction<40%. The study protocol included clinical evaluation, echocardiography (M-mode, 2D, Doppler and tissue Doppler) and laboratory tests including copeptin, vasopressin and NT-proBNP. We compared patients in NYHA class II with those in NYHA class>II. Overall mortality was assessed at 18 months. RESULTS: Mortality was higher in the more advanced symptomatic stages (p<0.05). Patients in NYHA class>II had higher creatinine, copeptin and NT-proBNP levels (p<0.05). E/E', E-septum distance, pulmonary artery systolic pressure (PASP) and inferior vena cava (IVC) dimensions were also significantly greater (p<0.05). The biomarkers copeptin (area under the curve [AUC]=0.76, p<0.01) and NT-proBNP (AUC=0.81, p<0.01) and the echocardiographic parameters PASP (AUC=0.88, p<0.01) and IVC inspiratory diameter (AUC=0.91, p<0.01) showed the best performance for diagnosis of functional class>II. In multivariate regression analysis only PASP and serum creatinine were independent predictors of NYHA functional class>II. CONCLUSION: Copeptin and NT-proBNP have high sensitivity and specificity in the diagnosis of functional classes with prognostic impact and may be useful in defining a standardized functional classification. The structural and hemodynamic echocardiographic changes associated with NYHA class>II were left ventricular filling pressure, PASP and central venous pressure.

[Takotsubo syndrome or acute myocarditis? The role of cardiac magnetic resonance imaging]. / Síndroma de takotsubo ou miocardite aguda? O papel da ressonância magnética cardíaca.

Acute myocarditis is often misdiagnosed, and its evolution is not always benign; correct and prompt diagnosis is therefore essential. We report the case of a 62-year-old woman with chest pain after a stressful event and ST-segment elevation on the electrocardiogram, in whom urgent cardiac catheterization showed normal coronary arteries and left ventricular apical ballooning, suggesting takotsubo syndrome. However, cardiac magnetic resonance imaging showed lesions typical of acute myocarditis, thus suggesting this diagnosis. We highlight the diagnostic difficulty in patients with chest pain, elevated troponin and normal coronary arteries, and the key role of cardiac magnetic resonance in differential diagnosis.
