Comparative Study[Acute myocardial infarction diagnosis. The value of serum myoglobin levels, compared with creatine kinase MB fraction].
To compare the diagnostic performance of two traditional plasma markers of myocardial infarction (MI), creatine kinase (CK) and its MB fraction (CK-MB), with plasma myoglobin (Mgb) levels, for the diagnosis of MI. ⋯ In the studied population, Mgb was more sensitive than CK-MB for the diagnosis of MI with similar specificity and Mgb was more specific than CK for this diagnosis.

Case Reports[Value of transthoracic Doppler echocardiography in the diagnosis and management of massive pulmonary embolism].
We report the case of a 62-year-old man with massive pulmonary embolism and severe hemodynamic impairment. Transthoracic Doppler echocardiography was fundamental in confirming the diagnosis by direct visualization of intra-atrial thrombus and signs of right chamber overload. It allowed prompt administration of thrombolytic drug and follow-up monitoring. Doppler echocardiography is a non-invasive, available technique and its early application should be considered in the evaluation of patients with suspected massive pulmonary embolism.

[When should we stop cardiopulmonary resuscitation in patients brought to the emergency room in cardiac arrest without pre-hospital care?].
The decision of stopping cardiopulmonary resuscitation (CPR) in patients brought to emergency room in arrest remains a challenge. Such decision is even more difficult when someone is brought by bystanders, after an acute loss of consciousness without any out-of-hospital care. To evaluate the probability of survival of these patients we reviewed retrospectively charts in our institution, during a period of five years. ⋯ Delayed arrival to the emergency room (> 15 min) associated with asystole were predictors of unsuccessful CPR, and both data are helpful in deciding when to stop CPR in subjects arriving at the emergency department with no out-of-hospital care.

[Intensive Care Unit stay. Variables that affect emotional reactions].
To evaluate the anxiety and depression levels during five days of stay in a Clinical Cardiological Intensive Care Unit (ICU) and verify the relation to different variables. ⋯ Anxiety and depression decrease during the five days of ICU stay. Emotional reactions are not influenced by medical diagnoses, age and number of hospitalizations. The emergency unit stay affects emotionally the patient in the first days of ICU admission.

[Atrial septal defect percutaneous transvenous occlusion with the buttoned device].
To analyse the experience with the use of Sideris' device for percutaneous transvenous occlusion of atrial septal defect (ASD). ⋯ The Sideris' device is safe and efficient for ASD occlusion in selected patients. Although there is a relatively high incidence of residual shunt immediately after the procedure, the shunt itself tends to become smaller or disappear during the follow-up and it does not preclude clinical and hemodynamic improvement.
