What Causes Petechiae?

Endocarditis

Endocarditis is a condition in which the inner lining of the heart, medically known as the endocardium, becomes inflamed. The condition is typically caused by bacteria, and it can also be triggered by an infection. The symptoms of endocarditis often develop gradually, and some cases may go undiagnosed. Common symptoms include fever, heart murmurs, joint pain, nausea, and a sensation of fullness in the upper left abdomen. Swelling of the abdomen, feet, or lower legs may occur, and some individuals experience a cough, shortness of breath, or blood in the urine. The petechiae that occur with endocarditis normally form on the whites of the eyes, the roof of the mouth, or the insides of the cheeks, and they might also be noticed on the chest. Patients could also have painful red spots located just underneath the skin of their fingers or toes. To diagnose endocarditis, doctors will listen to the patient's heart, and blood tests, echocardiograms, chest x-rays, and electrocardiograms may be performed. Treatment for endocarditis generally consists of both intravenous and oral antibiotics, and patients with the infective form may need surgery.
