CHRONIC COVID (or LONG COVID or PACS) IT IS A VASCULAR DISEASE.
View attachment 45505
To identify Hypoperfusion and Hyperlactacidemia, regular tomography or X-rays are not more useful.
Since the tissues are not damaged, or they only present macroscopically not visible lesions.
Routine blood tests are also usually normal or slightly abnormal.
What is required are specific blood tests to identify hypoperfusion, persistent clots, and cellular hypoxia.
We indicate the following 3 analyzes are carried out, which are not complex or high-cost (on average the cost is 20 to 40 US dollars each):
1) MEASUREMENT OF VENOUS BLOOD GASES.
If Venous Oxygen Saturation (SvO2) is low, it is assumed that the supply of oxygen to the tissues is decreased, and it is highly probable that there is Hypoperfusion.
If it is elevated, it would indicate as a first option that there are persistent clots.
If it is within the normal range, clots cannot be ruled out, since D-Dimer is a product of fibrin degradation, so if there is no breakdown or lysis of clots (as can occur in COVID Chronic) the D-dimer would not be elevated.
3) LACTATE (also known as Lactic Acid).
If it is elevated, it would indicate that there is cellular hypoxia.
Taking a blood sample to perform these 3 tests is similar to the procedure performed for routine blood tests such as hemogram or cholesterol, that is, the sample is generally taken from a vein in one of the patient's arms.
The amount of blood required is not much, and the patient does not need to be fasting.
Besides these 3 tests, do you think that if a person has ice cold hands and feet that that would likely indicate microclots as well?
