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 importance of cardiac magnetic resonance imaging in the diagnosis of myocarditis--a case report.

The authors describe the case of a 16-year-old male, who went to the emergency department with a clinical setting characterized by chest pain, electrocardiographic pattern of inferoposterior acute myocardial infarction and elevated markers of myocardial necrosis. Cardiac catheterization revealed no significant coronary lesions and the transthoracic echocardiogram showed no segmental abnormalities. Myocarditis was suspected, and this diagnosis was confirmed by magnetic resonance imaging.

Five cases of transient left ventricular apical ballooning--the experience of a Portuguese center.

Transient left ventricular apical dyskinesia (apical ballooning syndrome, ABS) is characterized by transient alterations in regional wall motion, involving the mid and apical segments of the left ventricle, as well as electrocardiographic alterations, mimicking ST-elevation acute myocardial infarction, in the absence of obstructive disease of the epicardial coronary arteries. In this article, we present a series of five cases of ABS and a theoretical review of the syndrome.

Early flow propagation velocity for assessment of diastolic function in myocardial infarction treated with acute reperfusion.

Introduction: Acute myocardial infarction (MI) causes left ventricular (LV) diastolic dysfunction, which influences prognosis and clinical evolution. Early flow propagation velocity (FPV), evaluated by color M-mode Doppler, has been demonstrated to be a diastolic function parameter with excellent correlation with relaxation constant tau, and is relatively independent of pre- and afterload.

Objective: The aim of this study was to evaluate left ventricular relaxation in MI patients treated with acute reperfusion therapy.

Evaluation of systolic and systo-diastolic function: the Tei index in acute myocardial infarction treated with acute reperfusion therapy--early and late evaluation.

Introduction: Evaluation of systolic and diastolic function by non-invasive methods in the acute phase of myocardial infarction (MI) is of great importance for risk stratification and prognosis. Ejection fraction (EF), as determined by echocardiography using the Simpson method, is the main parameter for assessing left ventricular (LV) function. The Tei index (TI), a Doppler-derived index that reflects systolic and diastolic function in MI, has an excellent correlation with prognosis.

Suspected dysfunction of a Starr-Edwards aortic prosthesis implanted 33 years ago: the role of exercise stress echocardiography. Case report.

The authors present a case report of suspected dysfunction of a Starr-Edwards mechanical aortic prosthesis implanted in 1972. Its characteristic longevity, but also its disadvantageous hemodynamic profile, are discussed. Treadmill exercise echocardiography, whose role has yet to be clarified in the study of valve prosthesis, was used in the evaluation of the patient.

Myocardial infarction in a patient with congenital coronary anomaly.

The authors describe the clinical case of a 38-year-old patient, with a history of smoking and hypercholesterolemia, who was admitted for non-Q wave acute myocardial infarction, and in whom coronary angiography revealed severe coronary disease and a congenital coronary anomaly. Unlike many congenital coronary anomalies that are manifested in ischemic disease, the nature of this patient's anomaly may have contributed to its benign clinical evolution, and influenced the therapeutic approach.

Valve orifice area in aortic stenosis evaluated by planimetry, Gorlin and continuity equations: a prospective study.

Unlabelled: In evaluation of the severity of aortic valve stenosis, multiple parameters can be determined. All of them, except valve orifice area, are influenced by other factors such as cardiac output, heart rate or aortic insufficiency.

Objectives: This is a prospective study which proposes, in the determination of the valve orifice area in aortic stenosis, to evaluate the accuracy of and correlation between three methods--planimetry by multiplane transesophageal echocardiography, the continuity equation by transthoracic echocardiography, and invasive measurement using the Gorlin formula.
