Question

68 y/o male who had an MI in April, 2015 was seen by his physician on Aug. 30, 2017 presenting with shortness of breath, fatigability, and swelling of the lower extremities. Upon physical examination, the man was found to have distended jugulars and pitting edema of the ankles. His breathing was rapid (20 breaths/min) and pulmonary crackles were heard bilaterally in the lower lobes of the lungs. He had a pulse rate of 110 beats/min and a BP of 152/98. Since his MI, he was taking digoxin and hydrochlorothiazide. At the time, the Px blood and urine work showed:

The Px was admitted at that time and was treated with 2L of 5% saline and Lasix® which removed the excess blood volume. The Px’s blood pressure, heart rate and respiratory problems were reduced. Additional lab tests indicated that the Px was experiencing left ventricular failure. Once he was stable, the Px was sent home on Sept. 2.

On Dec. 7, 2017, the Px was transported to the ER via ambulance after his daughter found him unresponsive. She told the ER physician that her father had been extremely fatigued at any level of effort, had extensive flank pain and that his mental alertness had decreased significantly over the past two weeks.   Physical examination finds that the Px is doesn’t respond to questioning and appears to fall asleep during the examination. Once again, the Px exhibits excessive swelling in the lower extremities with distended jugulars. His heart rate is now 92 and irregular, his BP is 164/110. His breathing is 28 breaths/min and shallow but lung sounds are normal. His urine is dark and foamy. The ends of his fingers and toes have a bluish appearance and his abdomen is large and distended.

An ECG was run on the Px and is shown below:

The attending physician immediately gave the Px 30 mg of propranolol and admitted the Px. An echocardiogram was conducted and showed right and left ventricular cardiomegaly.

What does the RBC and hemoglobin data indicate? What is the cause??

Explanation / Answer

Since the patient has problems with his jugular bone, automatically the bone marrow there might not be producing the red blood cells. As the normal RBC count in the male is 4.7 to 6.1 count micron per litre, Px has a lower blood count. So it's very natural that the patient would feel breathless and as the RBC count is low the level of oxygen will be obviously low which is also the reason for his fatigue.

Hemoglobin percentage measures the amount of iron content in the blood. The hemoglobin percentage in a male should at least be within 12 to 14%. So Px has a low hemoglobin percentage too which is only 9.5% and therefore that was the reason for body swelling especially the toes and fingers and he was laid down to bed and had to be hospitalized immediately. When the hemoglobin percentage decreases its place is taken by water in the body which led to the swelling of the abdomen.
