概括
冠状动脉旁路移植 (CABG) 为严重受损左心室功能 (Lo EF) 的患者提供可接受的外科手术风险和改善的生存率. 这个高风险群体现在比以前报告的结果更好.
科学领域:
- 心脏病学 心脏病学
- 心脏外科手术 心脏外科手术
- 临床结果研究研究
背景情况:
- 冠状动脉旁路移植 (CABG) 是冠状动脉疾病的标准治疗方法.
- 从历史上看,严重受损左心室功能 (LVF) 的患者预后不佳.
- 高风险LVF患者中CABG的当前结果需要更新估计.
研究的目的:
- 评估接受CABG的左心室功能严重减弱的患者的当代预后.
- 为了比较CABG的结果,在患有低,中等和正常射出分数 (EF) 的患者中.
主要方法:
- 在加拿大阿尔伯塔省,对1996-2001年APPROACH注册表数据的分析.
- 在7841名根据EF分类的患者中,单独的CABG结果的比较:Lo EF (<30%),Med EF (30-50%),Nl EF (>50%).
- 统计分析包括手术死亡率,5年生存率和调整后的危险比率.
主要成果:
- 在Lo EF (4.6%) 和Med EF (3.4%) 和Nl EF (1.9%) 组中,手术死亡率更高 (P<0.001).
- 在Lo EF患者中,五年生存率为77.7%,在Med EF患者中为85.5%,在Nl EF患者中为91.2% (P<0.001).
- 在Lo EF和Nl EF中死亡的调整风险比为1.98;在CABG和非再血管化的Lo EF患者中,1年死亡率较低 (OR0.36).
结论:
- 在左心室功能严重减弱的患者中,可以在可接受的外科手术期死亡率下进行CABG.
- 与历史数据相比,这个高风险组的当代5年生存率得到了改善.
- 对于精选的LVF受损的患者来说,CABG是一种可行的选择,比非再血管化提供生存益处.

Cardiac Catheterization II: Right Heart Catheterization
Right Heart Catheterization: An OverviewRight heart catheterization is an invasive diagnostic procedure that measures right-sided cardiac and pulmonary artery pressures, calculates cardiac output, and identifies intracardiac shunts. It provides detailed hemodynamic data essential for diagnosing and managing various cardiovascular conditions, such as pulmonary hypertension.Access SitesCommon access sites for right heart catheterization include the internal jugular vein in the neck region, the...
Cardiac Catheterization III: Left Heart Catheterization
Left heart catheterization is an invasive diagnostic procedure used to evaluate the function and structure of the left side of the heart. It is generally performed to diagnose and treat cardiovascular conditions such as valve abnormalities, coronary artery disease, and congenital heart defects.Diagnostic and therapeutic purposesLeft heart catheterization serves various diagnostic and therapeutic purposes, including:Assessing coronary artery bypass grafts.Evaluating coronary artery disease in...
Cardiomyopathy II: Dilated Cardiomyopathy
Dilated cardiomyopathy, or DCM, is a progressive myocardial disorder characterized by ventricular chamber dilation and contractile dysfunction.EtiologyVarious factors can cause DCM, including hypertension and heavy alcohol intake, which contribute to the weakening and enlargement of the heart muscle. Viral infections, such as Coxsackievirus B, adenoviruses, and influenza, can lead to DCM by causing inflammation and damage to heart tissue. Certain chemotherapeutic agents, including daunorubicin,...
Cardiomyopathy V: Interprofessional Care
Managing cardiomyopathy involves addressing underlying or precipitating causes, treating heart failure with medications, and implementing dietary changes and a balanced exercise and rest regimen.Lifestyle ModificationsCardiomyopathy patients should adopt a low-sodium diet to reduce fluid retention and manage heart failure. A personalized exercise and rest plan helps maintain physical fitness without overstraining the heart. Avoiding alcohol and tobacco is essential to prevent further damage to...
Cardiomyopathy VII: Pre and Post Operative Nursing Management
Patients with hypertrophic cardiomyopathy (HCM) and left ventricular outflow tract (LVOT) obstruction who remain symptomatic despite optimal medical therapy may undergo a septal myectomy (Morrow procedure). This procedure involves excising a portion of the hypertrophied septum below the aortic valve using a heart-lung machine to improve blood flow through the LVOT. Effective preoperative and postoperative nursing management ensures successful patient outcomes, minimizes complications, and...
