Can hypothyroidism cause an aortic aneurysm?

Can hypothyroidism cause an aortic aneurysm?

However, hypothyroidism has been found to be associated with aortic aneurysms. Some novel risk factors that have been studied and found to be associated with a decreased risk of cerebral aneurysm include hyperlipidemia and diabetes mellitus, as in our case-control study.

How does thyroid disease cause dilated cardiomyopathy?

Thyroid hormones have a significant impact on cardiac function and structure. Excess thyroid hormone affects cardiovascular hemodynamics, leading to high-output heart failure and, in late stages, dilated cardiomyopathy.

What does it mean when your aortic valve is dilated?

When the aortic root becomes dilated, this can mean the valve cannot fully close and the blood that flows out of the heart to the body can flow back into the heart as a result of aortic valve regurgitation.

Does hypothyroidism cause dilated cardiomyopathy?

Hypothyroidism can also cause DCM, and replacement treatment with levothyroxine can significantly improve myocardial function. Hence, thyroid function tests should be systematically performed in all patients with DCM to rule out hypothyroidism.

Can hyperthyroidism cause aortic aneurysm?

There was suggestive evidence of associations between hyperthyroidism and higher odds of AF and lower odds of thoracic aortic aneurysm; hypothyroidism and higher odds of CAD and hypertension; and increased FT4 levels and lower odds of peripheral arterial disease (Table).

Can thyroid cause aneurysm?

Abstract. Background: Endocrine dysfunction, including thyroid function, has been known to affect cerebral vascular dysfunction. Hypothyroidism has been shown to cause mucopolysaccharide deposition which has been associated with the weakening of blood vessel walls and aneurysm formation in some case reports.

Can thyroid cause enlarged heart?

Both an underactive thyroid gland (hypothyroidism) and an overactive thyroid gland (hyperthyroidism) can lead to heart problems, including an enlarged heart.

How serious is a dilated aortic root?

Aortic root dilation (AoD) imparts increased risk of aortic complications such as dissection, rupture, and valvular regurgitation. Multiple etiologies of AoD exist, such as Marfan syndrome, bicuspid aortic valve, Ehler-Danlos syndrome, infections, and idiopathic conditions.

What are the symptoms of a dilated aorta?

However as it enlarges, aortic dilation symptoms like these may include:

  • Pain in the chest or upper back. The pain may be deep, aching, gnawing, and/or throbbing, and may last for hours or days.
  • Shortness of breath, a raspy voice.
  • Pain in the left shoulder or between the shoulder blades.
  • Pain in the groin.

How does your thyroid affect your heart?

Insufficient thyroid hormone slows your heart rate. Because it also makes the arteries less elastic, blood pressure rises in order to circulate blood around the body. Elevated cholesterol levels, which contribute to narrowed, hardened arteries, are another possible consequence of low thyroid levels.

Can untreated hypothyroidism cause heart problems?

Severe cases of hypothyroidism can cause heart failure and death. Hypothyroidism is treated with thyroid hormone replacement, which can reverse most of these negative effects. However, overtreatment of hypothyroidism can result in high thyroid levels and fast and irregular heart rates.

Can hypothyroidism cause aneurysms?

Hypothyroidism has been shown to cause mucopolysaccharide deposition which has been associated with the weakening of blood vessel walls and aneurysm formation in some case reports.

How does thyroid affect your heart?

What causes a mildly dilated aortic root?

The primary cause of noninflammatory aortic root dilation is Marfan disease; the major causes of inflammatory aortic root dilation include giant cell aortitis, Takayasu’s disease, and syphilis. In these conditions, the inflammatory process generally does not affect the valve itself.

How common is a dilated aortic root?

Dilated aortic root (DAR) is a relatively common finding, with a reported prevalence of about 4% measured at the level of the sinuses of Valsalva in the general population.
