Hypothyroidism and the Heart

Area of Science:

• Cardiology
• Endocrinology
• Internal Medicine

Background:

• Hypothyroidism is a prevalent endocrine disorder with significant cardiovascular implications.
• Cardiac function is notably affected by thyroid hormone levels, influencing multiple hemodynamic parameters.

Purpose of the Study:

• To review the cardiac effects of overt and subclinical hypothyroidism.
• To summarize the impact of hypothyroidism treatment on cardiovascular parameters.

Main Methods:

• Literature review of studies investigating hypothyroidism and cardiovascular function.
• Analysis of clinical data on cardiac changes associated with thyroid dysfunction.

Main Results:

• Hypothyroidism adversely affects cardiac contractility, increases vascular resistance, and can lead to arrhythmias.
• Subclinical hypothyroidism also demonstrates detrimental cardiovascular effects, albeit often less pronounced.

Conclusions:

• Thyroid hormone status is critical for maintaining normal cardiac function.
• Effective management of hypothyroidism is essential for mitigating cardiovascular risks.
