Objective: To evaluate a possible evolutionary post-heart transplant return of autonomic function using quantitative and qualitative information from recurrence plots.

Methods: Using electrocardiography, 102 RR tachograms of 45 patients (64.4% male) who underwent heart transplantation and that were available in the database were analyzed at different follow-up periods.

Background: The acute kidney injury (AKI) is a complex disease for which there is no accepted standard definition nowadays. The Acute Kidney Injury Network (AKIN) represents an attempt to standardize the criteria for diagnosis and staging of acute renal dysfunction based on recently published RIFLE criteria, that means, (Risk, Injury, Failure, Loss, and End-stage kidney disease).

Objectives: To evaluate the incidence and associated mortality of AKI in patients submitted to on-pump coronary artery bypass graft surgery (on-pump CABG).

Background: Several infectious agents have been investigated since the association between atherosclerosis and infection was demonstrated; however, the results of these studies are contradictory.

Objective: To test the association between serum titers of anti-Chlamydia and anti-Mycoplasma antibodies in different forms of acute coronary syndromes (ACS).

Methods: One hundred and twenty-six patients were divided in 4 groups: ACS with ST-segment elevation (32 patients), ACS without ST-segment elevation (30 patients), chronic coronary artery disease (30 patients) and blood donors without known coronary disease (34 patients--control group).

Background: The aim was to demonstrate that a reduction in the nonlinear behavior of heart rate variability (HRV) in the preoperative period in patients undergoing coronary artery bypass graft (CABG) triggers higher morbidity and mortality rates in the postoperative stay.

Material/method: Seventy patients (59+/-10.3 years) were included.

Objective: It is common to obtain femoral venous approach in patients undergoing combined heart surgery or as an alternative to superior approach (internal jugular vein or subclavian vein). The aim of this study was to compare the measures of central venous pressure (CVP) at two different sites (superior versus femoral).

Methods: We prospectively and openly allocated 60 patients who underwent heart surgery between July from November 2006.

Objective: To verify the possible association between the levels of serum ferritin and the degree of obstructive coronary artery disease.

Methods: 115 patients with coronary arteriography and concomitant evaluation of serum ferritin were studied. The adopted cut-off values were 80 ng/ml for women and 120 ng/ml for men.
