Effects of Diseases

Heart Attack – Sometimes, oxygen-supplying arteries for the heart become blocked up by plaque and platelets. The heart cannot receive oxygen. It cannot proceed in pumping blood and oxygen throughout the body, leading to death.
Atherosclerosis – In atherosclerosis, fatty substances, cholesterol, and other wastes can build up in arteries. If the plaque ruptures, the blood can clot, leading to a heart attack or a stroke. Then, the heart cannot receive oxygen, leading to death.
Stroke – A stroke is a disturbance in the blood vessels that give blood to the brain. This may be caused by a blockage in the blood vessels, or accumulation of blood in the skull. If the heart cannot pump blood to the brain due to blockage, this means death.
Hypertension – Hypertension is the elevation of blood pressure. High blood pressure can wear the heart out, leading to early death.
Heart Murmur – Heart murmurs are caused by the valves closing as blood moves through the heart. Heart murmurs themselves, are an irregular noise. Abnormal murmurs may imply a defect with the heart valves, infection, disease, or age.
Congestive Heart Failure – Congestive Heart Failue is where the heart cannot pump enough blood to all of the body’s organs. The heart pumps blood slowly, and the returning blood backs up, causing congestion in the tissues.
