![]() ![]() Other heart conditions: Several other heart conditions can cause the left ventricle to thicken.When this happens, it puts you at higher risk for both systolic and diastolic heart failure as well as other heart conditions. These changes cause a mismatch between oxygen supply and demand. Some of these changes include increases in blood pressure, reduced oxygen delivery to the heart, and increased nervous system activity. This leads to a complex set of changes in the body. Obstructive sleep apnea (OSA): When you have OSA, you stop breathing while you sleep.All these conditions can contribute to diastolic heart failure. Sedentary lifestyle: A lack of physical activity can put you at higher risk of high blood pressure, diabetes, coronary artery disease, and obesity.Obesity: Increased fat padding around the heart makes it have to work harder.Both can limit the heart’s ability to fill with blood. A thickened outer covering on the heart is called pericardial constriction. Pericardial disease: Fluid around the heart is called pericardial tamponade.This can stop the heart from relaxing and filling as it should. Very low blood flow to the heart can lead to the death of heart muscle cells (ischemia). Coronary artery disease: Blockages permit less blood to flow through your heart.This makes the heart have to work harder, which can cause the muscle to thicken. Diabetes: High blood sugar levels may cause stiffening of blood vessels.This affects its ability to relax between beats. As a result, your heart gets more muscular and stiffer. When you have high blood pressure over a long time, your heart has to work harder to pump blood through your body. High blood pressure: Chronic hypertension is one of the most common causes of diastolic heart failure. ![]()
