Unit 4 Discussion Sovanny Than Introduction to Anatomy and Physiology: SC144-8M Herzing University/ Dr. Dawn Strauss-Berta August 2, 2023 A cardiovascular imbalance that I will be discussing is heart failure. Heart failure is a condition where the heart is unable to pump enough blood to meet the body’s needs ( Congestive Heart Failure: Symptoms, Stages & Treatment , 2023). This happens when the heart becomes damaged or weakened, from a heart attack or other underlying conditions. When the heart is not able to pump enough blood it can lead to many symptoms, including fatigue, shortness of breath, and swelling in the feet, ankles, and legs. When heart failure impacts the heart muscle, it can decrease perfusion, or blood flow to the heart. Over time this can cause damage and impact the functions of other organs and systems in the body. Heart failure at the cellular level can cause changes in the structure and function of heart muscle cells, which can weaken the heart's ability to pump blood as it should. Additionally, heart failure can impact the electrical signaling that occurs within the heart, leading to changes in the heart's rhythm and function. The heart’s electrical signaling can cause the heart to beat too fast (tachycardia), too slow (bradycardia), or irregularly ( Heart Arrhythmia - Symptoms and Causes , 2023). At the histological level, heart failure can lead to changes in the structure and organization of heart tissue, which can impact the heart's ability to contract and relax normally. One body system that can be impacted by heart failure is the respiratory system. When the heart is unable to pump enough blood, it can lead to a buildup of fluid in the lungs, which causes shortness of breath, coughing, and other respiratory symptoms. This can also lead to a condition called pulmonary edema. Pulmonary edema is an accumulation of fluid in the lungs which makes it difficult to breathe. Heart failure can also impact the body's ability to deliver oxygen to the tissues, which causes fatigue. Heart failure can not only affect the respiratory system, but it can also impact the digestive system and the urinary system causing a decrease in blood flow to the kidneys, nausea, and abdominal pain.
