Diastolic heart murmur

Diastolic heart murmur is a specific type of heart murmur that occurs during the diastolic phase of the cardiac cycle. This is the phase when the heart relaxes after contracting and allows blood to fill the ventricles.

Causes

Diastolic heart murmurs are usually caused by a narrowing or leaking of the heart valves. This can be due to a variety of conditions, including aortic stenosis, mitral stenosis, tricuspid stenosis, and pulmonic stenosis. Other causes can include heart failure, hypertension, and endocarditis.

Symptoms

The symptoms of a diastolic heart murmur can vary depending on the underlying cause. Some people may not experience any symptoms, while others may experience shortness of breath, fatigue, chest pain, or palpitations.

Diagnosis

Diastolic heart murmurs are typically diagnosed through a physical examination and listening to the heart with a stethoscope. Additional tests, such as an echocardiogram, may be used to confirm the diagnosis and determine the severity of the condition.

Treatment

The treatment for a diastolic heart murmur will depend on the underlying cause. This can include medications to manage symptoms, surgical procedures to repair or replace damaged heart valves, or lifestyle changes to improve overall heart health.
