[Guidelines of the Spanish Society of Cardiology for clinical practice in exercise testing]. / Guías de práctica clínica de la Sociedad Española de Cardiología en pruebas de esfuerzo.

Most exercise testing is performed in adults with known or suspected ischemic heart disease. In the last few years cardiac imaging techniques have been applied in this field, improving the information obtained with the procedure. However, the exceptions to this rule are emerging rapidly not only in healthy people (asymptomatic individuals, athletes, handicapped people) but also in cardiac patients (advanced congestive heart failure, hypertension, rhythm disorders, congenital heart disease, etc.). All the-se issues justify the need for a multidisciplinary consensus document in Spain. This paper reviews and updates the methodological aspects of the stress test, including those related to oxygen consumption measurements. The main aim of this review was to determine the role of exercise testing in the evaluation of ischemic heart disease as well as the applications of imaging stress testing. The usefulness of this test in other non-ischemic cardiac disorders and in selected subsets of healthy people is also reviewed.

[Pleuro-pericardial effusion following the early intragraft thrombolysis of an occluded aortocoronary graft]. / Derrame pleuropericárdico tras trombólisis precoz intrainjerto aortocoronario.

A case of contrast extravasation associated with pleuro-pericardial effusion occurring during recanalization of an early occluded aortocoronary bypass by intragraft fibrinolysis is reported. This is, to the best of our knowledge, the second report of angiographically demonstrated contrast extravasation from an aortocoronary bypass graft during this technique and the first associated with pleural effusion as a clinical manifestation.

[Ischemic cardiopathy in women]. / Cardiopatía isquémica en la mujer.

Life expectancy in western women is 8 years larger compared to men. This is due to the higher incidence of ischemic heart disease in men at least before reaching 45 years of age. This may also be due to differences in blood lipoprotein levels, differences in smoking habits, use of hormonal contraceptives, plasma iron levels, parity and other risk factors also found in men. After menopause the difference in the incidence of ischemic heart disease progressively decreases, basically because of a decrease in estrogen secretion. However, the role of estrogen supplement treatment in this group of women in the prevention of ischemic heart disease has not yet been clearly defined. The objectives of this study are to review the risk factors involved in the development of ischemic heart disease in women, the changes brought about by menopause and the possible beneficial effects of supplemental estrogens in the postmenopausal period.

[Current use of anti-hemostatics in ischemic cardiopathy]. / Empleo actual de los antihemostáticos en la cardiopatía isquémica.

Antihemostatic drugs are widely used in the treatment and prevention of ischemic heart disease. Fibrinolytic agents are prescribed in the early phase of acute myocardial infarction, to reduce its size and improve survival. Their use in unstable angina is still controversial. Anticoagulants have substantial benefit in myocardial infarction, unstable angina and primary prevention of coronary disease. Finally, antiplatelet agents are used in stable and unstable angina, myocardial infarction and high risk patients.

[Dysautonomic syncope. Diagnosis and treatment]. / Síncopes disautonómicos. Diagnóstico y tratamiento.

Inappropriate activation or disbalance of vasomotor reflexes may have a close relationship with the pathogenesis of disautonomic syndromes, a frequent underlying cause of recurrent syncope. A combined approach of meticulous historical data, physical examination and selected laboratory procedures may delineate the most common causes of recurrent syncope. Tests of autonomic function may be particularly helpful in the diagnosis of this entity. They include some non-invasive maneuvers such as stimulation of carotid sinus, Valsalva maneuver or tilt-table test. Therapy for this syndrome includes pharmacologic agents, surgical and radiotherapeutic maneuvers and atrioventricular sequential pacing. In this work we will present an overall formulation of the diagnostic evaluation and a therapy approach of the patient presenting with this complaint.

[Update on coronary syndrome X]. / Actualización sobre el síndrome X coronario.

Syndrome X is not a well-defined clinical entity. Patients included are those with typical effort angina with angiographically normal coronary arteries and with no evidence of other causes of chest pain. The pathophysiologic mechanisms involved in this syndrome could be a reduced vasodilatory capacity. The prognosis is usually good, but a subgroup of patients with left bundle brunch block in the ECG may develop a dilated cardiomyopathy. To present it lacks a full effective treatment.
