What are some symptoms of left ventricular diastolic dysfunction?


Quick Answer

Symptoms of both left and right diastolic dysfunction include congested lungs, water and fluid retention, an altered heartbeat, dizziness, and fatigue, notes WebMD. Diastolic dysfunction occurs when the left and right ventricles don't correctly relax after a contraction, so less blood re-enters the heart. Some patients exhibit no symptoms of diastolic dysfunction until it leads to diastolic heart failure.

Congested lungs cause difficult breathing when lying down or during exercise; wheezing and a dry cough may also be signs of fluid in the lungs, according to WebMD. Reduced blood flow to the kidneys leads to swelling in the abdomen, legs and ankles, and an increased urge to urinate at night. A lack of sufficient blood circulation causes the heart to beat faster and may produce an irregular heartbeat. Less blood flowing to the brain causes confusion and a light-headed sensation, and weakness occurs because muscles and organs don't receive enough oxygen and nutrients.

Doctors use an electrocardiogram to detect left ventricular muscle thickening, explains the International Heart Institute Foundation. An echocardiogram reveals information about diastolic function and the elasticity of the left ventricle. It may also uncover the cause of diastolic dysfunction, which may be aortic stenosis, high blood pressure, coronary artery disease or cardiomyopathy. Doctors treat diastolic dysfunction by treating the underlying condition. In cases where the cause is not immediately evident, doctors use exercise testing and blood pressure monitoring to detect coronary artery disease or high blood pressure.
