There may be symptoms of thyroid overactivity, such as weight loss, a fast or irregular heart rate, tremor, and perspiration; [1] [2] but such symptoms occur in only half of all cases. [5] The most common type of hyperthyroidism, Graves' disease , may additionally cause eye problems ( Graves' ophthalmopathy ) and skin changes of the legs ...
Both doctors say that signs and symptoms of valve damage can vary, but the main ones to be aware of are shortness of breath (particularly during exercise or any form of exertion) and chest pain or ...
Certain medications can have the unintended side effect of affecting thyroid function. While some medications can lead to significant hypothyroidism or hyperthyroidism and those at risk will need to be carefully monitored, some medications may affect thyroid hormone lab tests without causing any symptoms or clinical changes, and may not require treatment.
Beta-blockers are used to alleviate the symptoms associated with TM. But beta-blockers do not reduce the damage done by excess thyroxine. Medications such as propylthiouracil and methimazole are administered to block the release of thyroxine from the thyroid and to block the damage thyroxine inflicts on muscle fiber tissue.

It can alter cardiac function, with increased heart rate, increased left ventricular mass index, increased cardiac contractility, diastolic dysfunction, and induction of ectopic atrial beats. Long-term mild excess of thyroid hormone can thus cause impaired cardiac reserve and exercise capacity. [4]
Graves' disease, also known as toxic diffuse goiter or Basedow’s disease, is an autoimmune disease that affects the thyroid. [1] It frequently results in and is the most common cause of hyperthyroidism. [5]
The heart valve changes seen with moderate and intermittent use can result in permanent damage and life-threatening heart problems if use of the causative drug is increased or continued, however longitudinal studies of former patients suggest that the damage will heal over time to some extent at least.
Valve repair is where the valve that is causing heart failure is modified by removing excess valve tissues that cause them to close too tightly. In some cases, annuloplasty is required to replace the ring around the valves. If the repair of the valve is not possible, it is replaced by an artificial heart valve. The final step is heart replacement.
