Cardiac Issues in Thalassemia

Heart diseases are among the top reason behind death and morbidity in Thalassemia. Thalassemia major is classified by long-term inactive erythropoiesis. Anemia is also determined among its major complications.

This classification further develops physiologic adaptations in the cardiovascular mechanism. It also causes a number of deficiencies in pathologic and iatrogenic processes including splenectomy, iron overload, poor nutrition, stress, anxiety, weakness, and lung diseases. Thalassemia patients also suffer from cardiomyopathy, vascular aging and pulmonary hypertension.

The cardiovascular system of thalassemia patients is at a huge risk.  Chronic anemia, which is one of the companion health conditions for thalassemia suffers, demands more oxygen delivery from the cardiovascular system of a patient.

Increased Cardiac Output

The cardiovascular system does that by increasing the cardiac output, which causes increased cardiac dimensions and heart & pulse rate. That’s the reason why the cardio analysis of thalassemia patients is always abnormal. Their CXR, echo, holter, MRI, and other related diagnostic measurements are high.

Thalassemia patients also have low blood pressure or hypotension even with increased heart rate and cardiac output. 

This mainly happens because of poor resistance from the vascular system. This condition makes the patient’s condition highly vulnerable.

Iron Overload

Iron overload is a common complication for such patients. They get it through transfusional therapy. Iron surplus is atrocious for the body functions and parts that support healthy and normal cardiac activity.

Iron overload may also cause disturbance in insulin resistance and diabetes to thalassemia patients, worsening their condition. Adequate insulin resistance is essential for the utilization of cardiac energy.

Too much of iron content in the body affects thyroid and parathyroid glands that are important for metabolism and calcium regulation in the body.

Nutritional Deficiency

Nutritional deficiency is another factor that is present in thalassemia patients. Although this insufficiency is caused by the disease and allied health conditions, it does have a considerable impact of cardiac activities in the human body system.

Decreased Hemoglobin Level

The patient’s hemoglobin level is badly affected due to nutritional deficiency. It inherits chronic oxidative stress, furthering the intoxication of thalassemia. Vitamin (A, D, E, and K) levels adversely drop down, increasing the chances of cardiac and neurological toxicity.

Lung Conditions

Lungs too are not spared by the escorted complications of thalassemia. In the human body, lungs and heart are adjoining neighbors. Thalassemia patients have lung diseases - such as Inhomogeneous ventilation and small airways. When the hemoglobin of thalassemia patients is altered (with healthy blood), they experience easiness and more active.

Therefore, as you can see, each complication a thalassemia patient has to live with has an influence on his body’s cardiac and vascular activity. All these conditions lead to cardiac issues in thalassemia patients.
