Anemia Heart Disease Risk

Goo health - Iron deficiency causes anemia not only causes the body more easily tired and weary, but it could further increase the risk of heart disease. That's why do not regard lightly anemia.

Anemia is a condition in which the number of red blood cells or hemoglobin is below normal limits. As a result, blood can not transport oxygen in the amount as necessary for the body. .
WHO defines anemia in men when the concentration of hemoglobin (Hb) less than 13 g Hb / dL and less than 12 g Hb / dL in women. Although there are various types of anemia, generally the cause of everything is the same, namely, the lack of hemoglobin.


People with anemia, 50 percent are also equally harmful for heart disease than those without anemia. The reason for anemia, the heart must work harder to supply oxygen-rich blood to the tissues and other organs. This is the underlying why people often experience anemia with fatigue, shortness of breath after the move.


Increasing the heart in pumping blood seems to be bad. So, if this condition allowed to continue, can lead to heart enlargement, heart rate rapid / irregular, and heart failure.
Changes in heart function may also lead to increased preload, reduced peripheral vascular resistance, and increase output kardiac. The increased cardiac work may cause an increase in left ventricular mass and extra pressure on the heart wall.


Situations like this usually will be followed by a decrease of oxygen in the blood, causing a condition called myocardial ischemia (decreased blood supply to the heart muscle). All of these hemodynamic changes can cause heart failure.


A study conducted on mice in 2001 proved that chronic anemia can lead to the formation of new blood vessels when there is cardiomegaly. The investigators suggest that chronic anemia can lead to the formation of new blood vessels in the restructuring of the heart and microcirculation due to decreased oxygen in the blood or increased coronary blood flow caused by reduced blood viscosity.
Another study showed that chronic anemia caused blockages in the arteries of the neck, a condition that can lead to stroke.


Anemia can exacerbate existing heart conditions. Therefore, someone who has a history of heart disease should take extra precautions against the development of anemia.
