Interferences and interventions after acute myocardial infarction: an integrative review of the literature

Objective: to identify the interference of acute myocardial infarction (AMI) in the quality of life of affected, interventions and understanding by health professionals. Method: an integrative review, aiming to answer << What are the interference in the quality of life of post-AMI customers? >> and << What are the interventions proposed in order to minimize them? >>. We selected 12 articles available in the LILACS database, between 2000 and 2011, based on the criteria of inclusion and exclusion. Results: we have selected a total of 12 articles selected according to the inclusion and exclusion criteria pre-established. We obtained a classification into two themes (1) interference with quality of life and (2) proposals for interventions to minimize interference. Conclusions: highlights the importance of patient involvement in care plan well structured, multidisciplinary team integration and quantity of publications by heterogeneous country on the subject.

Parecoxib reduces renal injury in an ischemia/reperfusion model in rats

To evaluate the effect of parecoxib (an NSAID) on renal function by measuring plasma NGAL (serum neutrophil gelatinase-associated lipocalin) levels in an induced-ischemia rat model. METHODS: Forty male Wistar rats were randomly assigned to one of four groups: Ischemia (I), Ischemia/parecoxib (IP), No-ischemia (NI), and No-ischemia/parecoxib (NIP). Body weight, mean arterial pressure, heart rate, body temperature, NGAL levels, and renal histology were compared across groups. RESULTS: The Ischemia (I) group, which did not receive parecoxib, showed the highest NGAL levels (p=0.001), while the IP group, which received the medication, had NGAL levels similar to those of the non-ischemic (NI and NIP) groups. CONCLUSION: Parecoxib resulted in renal protection in this experimental model.

Dexmedetomidine on renal ischemia-reperfusion injury in rats: assessment by means of NGAL and histology

Background: Ischemic acute kidney injury is a common occurrence in the perioperative period and in critical patients admitted to intensive care units. The reestablishment of blood supply may worsen injury through the ischemia-reperfusion (I/R) mechanism. We investigated the effect of dexmedetomidine on the kidneys of rats subjected to an experimental I/R model. Methods: 34 rats anesthetized with isoflurane was undergone right nephrectomy and randomly assigned to four groups: Control C (saline solution); Dexmedetomidine D (dexmedetomidine); Sham S (saline solution); Sham with Dexmedetomidine SD (dexmedetomidine). The serum levels of neutrophil gelatinase-associated lipocalin (NGAL) were measured at time-points T1 (following stabilization), T2 (ischemia), T3 (reperfusion), T4 (12 h after of I/R). The kidneys were subjected to histological examination. Results: The NGAL levels were significantly higher at T4 compared with T1. Upon histological examination, the left kidneys in groups C and D exhibited a similar extent of cell injury. Conclusion: The levels of NGAL did not indicate either protection against or worsening of kidney injury. Histological examination for acute tubular necrosis showed that dexmedetomidine did not protect the kidneys from I/R.

Preoperative therapy restores ventilatory parameters and reduces length of stay in patients undergoing myocardial revascularization

Introduction: The frequency of surgical procedures has increased steadily in recent decades, including the myocardial revascularization.Objectives: To demonstrate the importance of physiotherapy in the preoperative period of cardiac surgery in relation to the reduction of hospital stay, changes in lung volumes and respiratory muscle strength.Methods: We conducted a prospective study with patients undergoing myocardial revascularization, the Hospital das Clinicas da Universidade Estadual Paulista (UNESP)/Botucatu - SP. We evaluated 70 patients of both genders, aged between 40 and 75 years, subdivided into two groups: group I - 35 patients of both genders, who received a written protocol guidance, breathing exercises and respiratory muscle training in the preoperative period and group II - 35 patients of both genders, who received only orientation of the ward on the day of surgery. This study was approved by the Ethics Committee of UNESP /Botucatu - SP.Results: Maximal inspiratory pressure in third postoperative day and fifth postoperative day and significant difference between groups, being better for the intervention group. Expiratory pressure was significant in fifth postoperative day in the intervention group compared to controls. The difference of length of hospital stay in the postoperative was found between the groups with shorter hospital stay in the group receiving preoperative therapy.Conclusion: Physical therapy plays an important role in the preoperative period, so that individuals in the intervention group more readily restored the parameters evaluated before surgery, in addition, there was a decrease in the time of the postoperative hospital stay. Thus, it is thought the cost-effectiveness of a program of preoperative physiotherapy.
