Fibroid heart is a term used to describe a heart that has become enlarged or thickened due to the presence of fibroids. However, there are several synonyms that can be used to describe this condition. These include hypertrophic cardiomyopathy, which refers to a thickening of the heart muscle, as well as left ventricular hypertrophy, which occurs when the left ventricle of the heart becomes enlarged. Other related terms include cardiomegaly, which is an enlargement of the heart in general, and myocardial fibrosis, which refers to the presence of fibrous tissue in the heart muscle. Regardless of the term used, fibroid heart can be a serious condition that requires medical attention and treatment.
