Angiotensin-converting enzyme inhibitors (ACE-I) were initially developed as therapeutic agents targeted for the treatment of hypertension. Since the initial application of these agents, several additional clinical indications have been identified such as coronary artery disease, stroke, congestive heart failure and prevention of diabetes-related complications. In addition to the blood pressure lowering effects, this class of agents has the ability to restore endothelial function, decrease oxidative stress and enhance endogenous fibrinolysis. Moreover, ACE-I possesses antiplatelet effects as well as antiproliferatory and antimigratory effects on smooth muscle cells. This article links the effects of ACE-I on thrombotic mediators to the potential clinical implications in the setting of coronary artery disease. 相似文献

A consensus conference on frailty in solid organ transplantation took place on February 11, 2018, to discuss the latest developments in frailty, adopt a standardized approach to assessment, and generate ideas for future research. The findings and consensus of the Frailty Heart Workgroup (American Society of Transplantation's Thoracic and Critical Care Community of Practice) are presented here. Frailty is defined as a clinically recognizable state of increased vulnerability resulting from aging-associated decline in reserve and function across multiple physiologic systems such that the ability to cope with every day or acute stressors is compromised. Frailty is increasingly recognized as a distinct biologic entity that can adversely affect outcomes before and after heart transplantation. A greater proportion of patients referred for heart transplantation are older and have more complex comorbidities. However, outcomes data in the pretransplant setting, particularly for younger patients, are limited. Therefore, there is a need to develop objective frailty assessment tools for risk stratification in patients with advanced heart disease. These tools will help to determine appropriate recipient selection for advanced heart disease therapies including heart transplantation and mechanical circulatory support, improve overall outcomes, and help distinguish frailty phenotypes amenable to intervention. 相似文献

? Various techniques involving skin grafts have been described to obtain thin hairless immobile skin at the abutment interface of the bone‐anchored hearing aid (BAHA), but none are without significant complications such as necrosis and/or infection leading to total graft failure. ? A novel technique involving four local thin skin flaps was developed to prevent serious complications. ? The procedure essentially involves raising skin flaps at the intradermal level leaving the hair follicles in the subcutaneous tissue, which is subsequently excised. ? We have used the skin‐flap approach around 21 BAHAs on 19 patients (two patients had bilateral devices) and the only complications were minor skin loss immediately adjacent to the implants in two patients and mild skin infections, which settled with topical antibiotics, in three patients. ? The innovative technique described is simple and straightforward, and does not require any special instrumentation. Furthermore, it may have specific advantages, in terms of morbidity, over contemporary skin grafting methods primarily because of the retained intrinsic blood supply of the skin flaps. 相似文献

Parents usually give the history of symptoms to us whenever a child is brought to us. Child is neither asked about his symptom nor his feelings related to the problem by most of jus. This paradox often results into resentment by the child biaking our examination more difficult. History given by a child often differs from that given by his parents. More than treating the Paediatric patients by medicines and surgery by special approach, technique or equipments, it is the understanding the Psychology of the children complaining of symptoms or suffering from a disease makes an ENT specialist a Paediatric ENT specialist. Child Psychology for paediatric ENT disorders are neither found in any book. One learns by keeping the eyes and ears open, by constant observation and analysis and from the experience of seniors. 相似文献
