[Diagnosis of perioperative myocardial infarction within the first seventy-two hours after cardiac surgery].

Unlabelled: One of the most frequent complications of cardiac surgery is the perioperative myocardial infarction (PMI). Incidence of PMI shows a wide variation because an accurate detection of this complication is difficult in the early postoperative stage. The objectives of the present study were to determine in our population of patients the incidence of PMI during the first seventy two hours after cardiac surgery as well as associations among the accepted criteria to diagnose this complication.

[Correlation between left ventricular stroke work loss index and aortic valve area in patients with aortic stenosis].

Unlabelled: In echocardiographic evaluation of patients with aortic stenosis (AS), prospective studies have demonstrated that left ventricular stoke work loss index (LVSWLI) provide a more clinical efficacy than calculate of aortic valve area (AVA) by continuity equation to estimate severity of stenosis. The aim of this study was assess in our population of patients with AS the correlation between LVSWLI and AVA in regard to severity.

Material And Methods: Forty nine patients with moderate and severe AS were evaluated by transthoracic echocardiography.

[Correlation between chest radiography and the echocardiogram to evaluate cardiomegaly in patients with systemic arterial hypertension].

Unlabelled: The chest radiography is used routinely by the clinician as a tool in the scan of patients with systemic arterial hypertension (SAH) to evaluate the dimensions of the heart. However the highest reported sensitivity for the evaluation of heart growth with this method is 77.3% in contrast to the transthoracic echocardiogram (TTE) that reaches between 90 to 100%.
