Staphylococcus aureus is the most common causative organism for infective endocarditis. This bacterium is responsible for approximately 30-40% of all cases of infective endocarditis. It's important to note that while other bacteria can cause endocarditis, S. aureus is particularly virulent and can affect both native and prosthetic heart valves. Understanding the predominant causative organisms helps emergency nurses anticipate potential complications and guide initial management strategies.
