Coronary artery bypass surgery in patients with left ventricular dysfunction.
The American Journal of Medicine
|March 1, 1986
Summary
Coronary artery bypass surgery improved symptoms and heart function in patients with left ventricular dysfunction. This surgery offers benefits for selected patients with reduced ejection fraction.
Area of Science:
- Cardiovascular Surgery
- Cardiac Function Assessment
Background:
- Left ventricular dysfunction (LVEF < 45%) poses significant risks.
- Surgical interventions for this population require careful evaluation.
Purpose of the Study:
- To assess coronary artery bypass surgery outcomes in patients with left ventricular dysfunction.
- Evaluate impact on survival, symptoms, and cardiac function.
Main Methods:
- Prospective study of 34 patients with LVEF < 45%.
- Serial assessment of global and regional left ventricular function using nuclear angiocardiography.
Main Results:
- Operative mortality was 9%, with 10% follow-up mortality.
- Significant improvement in anginal symptoms (20/21 patients) and heart failure symptoms (7/10 patients).
- Global LVEF (p<0.05) and regional systolic function (p<0.005) improved post-surgery.
Conclusions:
- Coronary artery bypass surgery is feasible with acceptable mortality in selected patients with LV dysfunction.
- Surgery can lead to significant symptomatic and functional improvements.

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...

Interprofessional care for coronary artery disease includes pharmacological therapy and revascularization procedures.Pharmacological therapy for Coronary Artery Disease (CAD) aims to manage symptoms, prevent complications, and improve patient outcomes through various classes of medications:Antiplatelet Agents:Aspirin and Clopidogrel: These medications inhibit platelet aggregation, preventing blood clots, which is crucial for avoiding heart attacks and strokes. Doctors often prescribe these...
01:30Cardiomyopathy 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,...

Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...
01:29Cardiomyopathy 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...
01:28Cardiomyopathy 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...
