blood test anemia Anemia is not included as a direct complication of heart disease. But according to a study, 1 in 5 patients in the hospital with heart disease also have anemia because they have their blood taken for tests too often.

The more often the blood is drawn for various types of examinations at the hospital, the greater the risk of heart disease to a patient affected by anemia. Each blood sampling of 50 mL, patients experience an increased risk of anemia by 18 percent.

Dr. Mikhail Kosiborod, a cardiologist from St Luke’s Hospital Mid-America Heart & Vascular Institute revealed the average heart patient’s blood are taken as much as 173.8 mL during hospitalization. The longer treated, the more blood drawn.

In a study involving 18,000 patients in 57 hospitals as the United States, Dr. Kosiborod found that taking blood safely is 100 ml. When the blood is taken to that volume, the patient has not experienced an increased risk of anemia.

The results also revealed that 20 percent or about 1 in 5 patients with heart disease have anemia. Perceived symptoms include headaches usually last up to a month later, but in some cases even worsen.

In a research report published in the Archives of Internal Medicine, Dr. Kosiborod said that anemia can be fatal because it can lead to death. The function of red blood cells is to carry oxygen, so that if the amount decreases, then the organs will lack oxygen.

“Taking blood in hospitals is very common, especially in the Intensive Care Unit (ICU). The problem is that some hospitals take patients blood more than others,” said Dr. Kosiborod, according to HealthDay.

Although having the risk of triggering anemia with moderate to severe severity, Dr. Kosiborod does not intend to prohibit hospitals to perform blood tests. But the amounts of blood taken should not overdo it, as much as possible to the minimum required.
