Pulmonary hypertension is high blood pressure within the artery that connects the lungs and heart. It forces the heart to work harder to transfer blood between the heart and lungs, which may lead to an enlargement of the right side. Thyroid problems, whether they involve an underactive or overactive thyroid, can cause a heart to enlarge.
The cause of cardiomyopathy, a thickening or enlarging of the heart muscle, may depend on the type: Dilated cardiomyopathy. The cause of this most common type of cardiomyopathy often is unknown. It may be caused by reduced blood flow to the heart (ischemic heart disease), infections, toxins and certain drugs. It also may be inherited from a parent. It usually enlarges (dilates) the left ventricle.
