Thyroid hormones secreted by thyroid gland can act on all organs of the whole body, including the heart. Therefore, if thyroid gland has problems, the heart may also have problems.
Arrhythmia caused by hyperthyroidism
Excessive secretion of thyroid hormone in hyperthyroidism causes rapid and strong contraction of the heart, which is prone to myocardial ischemia and hypoxia.
The heart becomes hypertrophic, the [doors and windows] between the heart chambers cannot be closed, and the [circuit system] of the heart will also be affected and arrhythmia (such as tachycardia, atrial fibrillation, premature beats, etc.) will occur.
In the long run, the burden on the heart is getting heavier and heavier, and eventually exhaustion is what is called heart failure in medicine.
You know, the normal operation of the whole body cannot be separated from the support of the heart, the heart failure, the whole person is not good.
Coronary heart disease caused by hypothyroidism
When hypothyroidism occurs, thyroid hormone secretion is too low, which will lead to an increase in blood lipid and coronary heart disease over time.
In addition, hypothyroidism, there will be a kind of mucin deposition in all parts of the body, not only will cause edema of limbs, face, but also will cause edema of the heart and produce pericardium (is the coat of the heart) effusion, limiting the beating of the heart. The final result is also heart failure.
Thyroid cancer is also at risk for heart disease.
Some thyroid cancer patients need to take thyroxine to inhibit the recurrence and metastasis of cancer after operation. The dosage of thyroxine is relatively large, which is equivalent to artificially producing hyperthyroidism.
Therefore, thyroid cancer patients may also suffer from heart diseases common to hyperthyroidism patients-heart enlargement, arrhythmia and heart failure.
These five symptoms should be paid attention to.
It can be seen that patients with hyperthyroidism, hypothyroidism and thyroid cancer all need to be alert to heart problems. Attention should be paid to the following five symptoms and timely treatment should be given.
1. Palpitations
That is, what is commonly referred to as “palpitation”, is a feeling that the heart beats wildly or with special force.
Palpitation symptoms are common in arrhythmia caused by hyperthyroidism.
2. Chest tightness
Chest tightness is a feeling of chest tightness, blockage and oppression.
Chest tightness symptoms are common in pericardial effusion caused by hypothyroidism, and also common in myocardial ischemia and hypoxia caused by hyperthyroidism/hypothyroidism.
3. Chest pain
Chest pain refers to the pain behind the left chest or sternum, which can be stuffy pain, colic and compression-like pain.
Chest pain symptoms are common in arrhythmia caused by hyperthyroidism or coronary heart disease caused by hypothyroidism.
4. Edema
Edema usually occurs in both legs and feet and is a typical manifestation of heart failure.
Hyperthyroidism and hypothyroidism may cause heart failure.
Hypothyroidism itself can also cause edema, but edema caused by heart disease can see a concave fossa when pressing the skin, and edema caused by hypothyroidism cannot press out the fossa.
5. Dyspnea
Dyspnea is a state in which breathing is very laborious, and it is especially serious when lying down, and it will improve when sitting up.
Dyspnea is also a typical manifestation of heart failure. Hyperthyroidism and hypothyroidism may cause heart failure.
In addition, hypothyroidism will not only produce pericardial effusion, but also pleural effusion, which will prevent normal lung expansion and cause dyspnea.
Early treatment can cure
Heart disease caused by hyperthyroidism and hypothyroidism has one characteristic: after the thyroid function is well controlled, heart disease can be rapidly relieved; If treated in time, heart disease can disappear completely.
Therefore, when there are abnormalities, you should go to the hospital early, find them early, treat them early and recover early!
