Influence of time elapsed between myocardial infarction and coronary artery bypass grafting surgery on operative mortality. 总被引:1,自引:0,他引:1

OBJECTIVE: Optimal timing for CABG surgery after myocardial infarction (MI) remains controversial. We examined the influence of patient age and time elapsed between MI and isolated CABG surgery on operative mortality. METHODS: Perioperative data of 13,545 patients who underwent isolated CABG surgery from 1991 to 2005 were reviewed. A previous MI was found in 7219 patients, classified among groups A-E whether they underwent surgery less than 6h (A, n=26), between 6 and 24h (B, n=51), between 1 and 7 days (C, n=313), between 8 and 30 days (D, n=917), or more than 30 days (E, n=5912) after the event. Crude percentages and odds ratio estimates of operative mortality were calculated. RESULTS: In patients who had no history of MI, the mortality rate was 1.7%, while it was, respectively, 19.2, 9.8, 8.6, 3.2, and 2.4% in patients from groups A to E. Among 6589 patients over 65 years of age, 3027 had no history of MI. Their mortality was 2.4%, compared to, respectively, 35.7, 13.8, 11.3, 5.1, and 3.9% for those belonging to groups A-E. Overall odds ratio estimates of operative mortality were 3.92 (p=0.19), 5.08 (p=0.002), 4.33 (p=0.0001), 1.50 (p=0.08), and 1.18 (p=0.24) for groups A-E, respectively. CONCLUSIONS: Operative mortality is not influenced by a history of MI sustained more than 30 days prior to isolated CABG surgery, but is highly and most significantly increased between 6h and 1 week after MI, especially in older patients. That critical period should be avoided whenever possible. 相似文献

Functional signatures of protective antiviral T-cell immunity in human virus infections 总被引:9,自引:0,他引:9

Summary: The most common human viruses have different abilities to establish persistent chronic infection. Virus‐specific T‐cell responses are critical in the control of virus replication and in the prevention of disease in chronic infection. A large number of phenotypic markers and a series of functions have been used to characterize virus‐specific CD4+ and CD8+ T‐cell responses, and these studies have shown great phenotypic and functional heterogeneity of the T‐cell responses against different viruses. The heterogeneity of the T‐cell response has been proposed to be specific to each virus. However, over the past 2 years, several studies have provided evidence that the phenotypic and functional heterogeneity of CD4+ and CD8+ T‐cell responses is predominantly regulated by the levels of antigen load. The levels of antigen load modulate the phenotypic and functional patterns of the T‐cell response within the same virus infection. Furthermore, the functional characterization of virus‐specific CD4+ and CD8+ T‐cell responses has identified signatures of protective antiviral immunity. Polyfunctional, i.e. interleukin‐2 and interferon‐γ (IFN‐γ) secretion and proliferation, and not monofunctional, i.e. IFN‐γ secretion, CD4+ and CD8+ T‐cell responses represent correlates of protective antiviral immunity in chronic virus infections. 相似文献

The proof for the general evolution of metastatic neuroblastoma from localized disease by a low-speed process is lacking. The epidemiological approach would require the decrease of neuroblastoma related mortality by reduction of the number of metastatic cases per population unit as a result of a screening program. During 1983 through 1990 the neuroblastoma incidence in the FRG was 0.85-1.09 cases per 100,000 children less than 15 years of age. The mortality rate ranged between 0.25 and 0.49 deaths per 100,000 children. The project "Niedersachsen/Nordrhein-Westfalen" started April 1st, 1992 and is investigating urinary catecholamine metabolite excretion in infants at the age of 10-12 months and for a second time in toddlers at 17-19 months. The target population includes 24.7 million inhabitants with 267,000 births per year. The urine sampled on filter paper is analyzed using thin layer chromatography. Positive and questionable positive results are confirmed by HPLC and GC-MS. The aim of the study is to demonstrate the feasibility of the chosen approach. Furthermore first epidemiological data will be obtained. Until a population-based study on neuroblastoma mortality in screened versus controlled populations has proven the usefulness of the screening it cannot be recommended as a general service to the public. 相似文献

Traumatic tricuspid insufficiency (TTI) is a rare lesion but is classically encountered as a "steering-wheel injury" in nonbelted car divers. This lesion is often not diagnosed because of its subtle clinical manifestations at first and the presence of associated injuries in multiple trauma. The majority of patients reported were treated with valve replacement but, more recently, successful repair of the native valve has made the latter the treatment of choice. Three patients were referred to us with a delayed diagnosis of TTI 2, 4, and 8 years after being involved in motor vehicle crashes (MVCs). Surgery was required and consisted of resuspension of the valvular leaflet with autogenous pericardium and ring annuloplasty. Two-dimensional echocardiography confirmed tricupid valve competence and the patients remained symptom free at a mean follow-up of 25 months. 相似文献

Heart-skin syndrome and cardiac myxoma: presentation of a case and clinical experience of 17 years.]

Between 1971 and 1988, cardiac myxoma was identified in 13 (0.003%) of 4000 patients who underwent open-heart surgery at the h?pital du Sacré-Coeur in Montreal. One patient with multiple right atrial tumours also had abnormal cutaneous pigmentation compatible with the recently identified syndrome of "Carney's complex." This syndrome has also been associated with endocrine abnormalities such as primary nodular adrenal hyperplasia, with or without Cushing's syndrome. The authors review the literature and compare the findings with their experience in the surgical treatment of cardiac myxomas. 相似文献
