body system there are homeostatic imbalances and one for the cardiac system is heart failure. Heart failure on the left side can happen in two ways‚ systolic heart failure and diastolic heart failure. A systolic heart failure is when the left ventricle cannot contract normally‚ which causes a decreased amount of oxygenated blood in the body because the heart cannot pump the blood efficiently. A diastolic heart failure is when the left ventricle cannot relax normally. This is because the heart muscle
