33
cardiac arrest
An event in which the heart abruptly stops beating or develops arrhythmia that prevents it from pumping blood effectively.

To stop or control bleeding.
51
leukemia
A type of cancer characterized by a progressive increase in the number of abnormal leukocytes (white blood cells) found in blood-forming tissues, other organs, and in the circulating blood.
52
leukocytes
White blood cells that are involved in defending the body against infective organisms and foreign substances.
53
leukopenia
A decrease in the number of disease-fighting white blood cells circulating in the blood.
54
megaloblastic anemia
A blood disorder characterized by anemia in which red blood cells are larger than normal.
55
myelodysplastic syndrome
A type of cancer in which there is insufficient production of one or more types of blood cells due to dysfunction of the bone marrow.
56
myocardial infarction
The occlusion (blockage) of one or more coronary arteries caused by plaque buildup; commonly known as a heart attack.

62
sepsis
A potentially life-threatening infection that results from bacteria or other infectious organisms entering the bloodstream.
