Heart diseases impair blood circulation in the body. The blood delivers oxygen and nutrients to every organ of the body. When the heart fails to pump out sufficient amount of blood, supply of oxygen and nourishment to the organs dwindles, which affects the functions of every organ of the body. Hence, a diseased heart affects the entire body.
There are various causes of heart diseases. Cardiac disorders may develop due to partial or complete blockage of the coronary blood vessels, problems in the cardiac electrical system, damaged valves and problems in the functioning of the heart chambers.
How Heart Disease Affects Our Body
Effect On Brain
There is an intimate relation between heart function and brain health. Your brain cannot function properly if it fails to get sufficient supply of oxygenated blood. As a result people with a diseased heart may experience difficulty in thinking. The cognitive function of people suffering from heart diseases tends to decline over time. Sudden cessation of blood flow to the brain causes stroke.
Effect On Kidneys
Heart disease is also bad for the health of the kidneys. The kidneys help in filtering wastes and toxins from the blood. The filtering capacity of the kidneys depends on the pressure of the blood. When the diseased heart fails to supply sufficient blood to the kidneys, they cannot carry out their normal filtering activities. As a result excess fluid accumulates in the blood stream. To remove the excess fluid from the body, the heart is forced to work harder.
Hence, the blood pressure level rises. High blood pressure damages the kidneys. Moreover, it causes more damage to the heart. Congestive heart disease patients also have a higher risk of developing acute tubular necrosis. Loss of oxygen supply, owing to slow down in blood flow to the kidneys, kills the kidney tissues, causing serious damage to the kidneys that apart from harming the kidneys, worsens heart problems.
Effect On Liver
Congestive heart disease that causes significant reduction in blood circulation in the body causes liver dysfunction. Passive congestion of the liver that occurs due to right heart failure causes abnormal increase in the liver enzymes, a sign of severe injury to the liver tissues.
Effect On Intestines
Abnormal low pressure (hypotension) or reduction in blood flow to the intestines causes intestinal ischemia. Although both the large and the small intestines are susceptible to intestinal ischemia owing to heart failure, it primarily affects the large intestine or colon.
Abdominal pain, frequent bowel movement, blood in the stool, fever, nausea and vomiting are common symptoms of acute intestinal ischemia.
Effect On Lungs
Pulmonary edema is a serious respiratory problem that occurs due to heart diseases.
It occurs when the pressure in the left atrium, veins and capillaries increases when the diseased left chamber of the heart fails to pump out sufficient amount of blood that comes from the lungs. As a result fluid accumulates in the lungs leading to shortness of breath and chest pain.
