Incidence of stroke and acute renal failure in patients of postoperative atrial fibrillation after myocardial revascularization

Introduction

Postoperative atrial fibrillation is the most common arrhythmia in cardiac surgery, its incidence range between 20% and 40%.

Objective

Quantify the occurrence of stroke and acute renal insufficiency after myocardial revascularization surgery in patients who had atrial fibrillation postoperatively.

Methods

Cohort longitudinal bidirectional study, performed at Portuguese Beneficent Hospital (SP), with medical chart survey of patients undergoing myocardial revascularization surgery between June 2009 to July 2010. From a total of 3010 patients were weaned 382 patients that presented atrial fibrillation preoperatively and/or associated surgeries. The study was conducted in accordance with national and international following resolutions: ICH Harmonized Tripartite Guidelines for Good Clinical Practice - 1996; CNS196/96 Resolution, and Declaration of Helsinki.

Results

The 2628 patients included in this study were divided into two groups: Group I, who didn''t show postoperative atrial fibrillation, with 2302 (87.6%) patients; and group II, with 326 (12.4%) who developed postoperative atrial fibrillation. The incidence of stroke in patients was 1.1% without postoperative atrial fibrillation vs. 4% with postoperative atrial fibrillation (P<0.001). Postoperative acute renal failure was observed in 12% of patients with postoperative atrial fibrillation and 2.4% in the group without postoperative atrial fibrillation (P<0.001), that is a relation 5 times greater.

Conclusion

In this study there was a high incidence of stroke and acute renal failure in patients with postoperative atrial fibrillation, with rates higher than those reported in the literature.

Quality-of-Life and Psychosocial Aspects in Patients with Ocular Toxoplasmosis: A Clinical Study in a Tertiary Care Hospital in Brazil

ABSTRACT

Purpose

To evaluate quality of life in patients with uveitis-related to toxoplasmosis and its correlation with demographic, ocular involvement and psychosocial aspects.Methods: Data were collected through standardized interviews using a form to collect clinical and demographic data, in addition forms such as HADS, SF-12, NEI-VFQ-25 for health-related quality of life and anxiety and depression symptoms.Results: 81 patients were included with a mean age of 41.5 ± 14.5 years, females (50.6%) They were divided into three categories of best corrected visual acuity in the better seeing eye: normal (0-0.4 logMAR, 60 participants), low vision (0.48-0.9 logMAR, 9 participants) and blindness (>1 logMAR, 12 participants). The mean of VFQ-25 score was 75.5 ± 19.5 and the mean of SF-12 physical and mental components scores were 48.5 ± 7.4 and 52.4 ± 10.6 for health-related quality of life (HRQol). Anxiety symptoms were most prevalente than depression and were found in 38% of the subjects.Conclusions: Slightly more than a quarter of the sample presented impaired vision. It is associated with worsening of the quality of life since it affects mostly mental and related to the vision domains. This affects familiar, social and in addition, labor relations, since the majority of the subjects are in the economically active age group.     

Fatal herpes simplex virus type 2 hepatitis in a heart transplant recipient: a case report and review of the literature

Herpes simplex virus (HSV) hepatitis is often unrecognized clinically with most untreated cases diagnosed postmortem. HSV hepatitis has been reported in solid organ transplant (SOT) recipients, mostly in kidney and liver transplants, and rarely in heart transplant recipients. We describe a fatal case of community‐acquired HSV‐2 hepatitis in a 24‐year‐old heart transplant recipient occurring 3 years after transplant. We also review the literature summarizing HSV hepatitis and the potential role of quantitative HSV polymerase chain reaction monitoring in the SOT population.
