How is thyroid linked to heart disease?
Heart disease can occur with both increased function of the thyroid gland and decreased function of the thyroid gland. When thyroid function is increased, heart rate increases and the work load of the heart increases.
In severe cases heart failure may occur. A peculiarity of heart failure associated with increased thyroid function is that it is a high output failure unlike the usual heart failure in which the pumping function of the heart is reduced, and low output failure occurs.

2.76 -> How is thyroid linked to heart disease?
Heart disease can occur with both increased
11.21 -> function of the thyroid gland and decreased
function of the thyroid gland. When thyroid
17.199 -> function is increased, heart rate increases
and the work load of the heart increases.
23.06 -> In severe cases heart failure may occur. A
peculiarity of heart failure associated with
28.97 -> increased thyroid function is that it is a
high output failure unlike the usual heart
36.069 -> failure in which the pumping function of the
heart is reduced, and low output failure occurs.
43.36 -> While in low output heart failure the extremities
are cold, in high output failure due to increased
50.789 -> thyroid function, the extremities of the limbs
are warm. Another important issue with increased
57.75 -> thyroid function is that the heart rhythm
may become irregular.
62.309 -> This condition is known as atrial fibrillation,
in which the upper chambers of the heart generate
68.73 -> very fast irregular signals but fail to contract
well.
74.17 -> Hence the blood stagnates in some parts of
the upper chambers (left atrium) and clots
80.8 -> may form. If these clots migrate to the blood
vessels of the brain, a stroke may result.
88.06 -> Reduced function of the thyroid gland is also
associated with heart disease. Cholesterol
94.25 -> levels go up when thyroid function comes down.
This in turn can enhance the chance of plaque
101.31 -> build-up in the blood vessels of the heart
(coronary arteries).
105.67 -> When thyroid function is very low, fluid collects
in various parts of the body. This may occur
112.23 -> within the covering of the heart known as
pericardium.
116.09 -> Collection of fluid within the covering of
the heart is called pericardial effusion.
120.89 -> If it is severe enough to compress the heart,
it prevents proper filling of the heart and
126.45 -> blood pressure falls.
Ultrasound image of the heart – echocardiogram,
131.75 -> showing fluid collection around the heart,
marked as PE, short for pericardial effusion.
