When the cardiac muscle is unable to pump blood as effectively as it should, heart failure results. Blood frequently pools, causing fluid to accumulate in the legs and lungs (congestion). Breathing problems and swelling in the feet and legs might result from fluid buildup. A deposition of calcification and other biochemical processes occurring in the body that generate toxic free radicals damage the heart muscle in some forms of chemotherapy, especially those that belong to the anthracycline medication class. A lack of blood flow might make the skin seem blue (cyanotic). Exercise, medication, and maybe surgery are all part of the course of treatment for heart failure. Just how you take better care of yourselves is one of the aspects that affect your attitude.
