This title is also a section found in the book titled: "Common Murmurs, Arrhythmias and Myopathies of the Heart" and is being made available for readers interested in heart conditions related to thyroid disease specifically. DESCRIPTION OF THIS TITLE: Thyroid disease is a major contributor to heart conditions of various types and can manifest as either hypothyroid or hyperthyroid disorders. This is why it is very important for both men and women (especially women), to be checked for abnormal thyroid hormone levels, beginning at age 35. A check for developing hypothyroidism or hyperthyroidism should also be done, at any point in life regardless of age, when symptoms of either condition appear to be developing. Catching and treating thyroid disorders at their earliest stages, can help to prevent associated heart conditions from also developing or from worsening if already present. When people become thyroid hormone imbalanced, this can also exacerbate an already existing cardiac condition, which also means that treatments determined to be needed, by a qualified medical doctor or doctors (plural in cases when both an endocrinologist and cardiologist are needed), require more diligence on the part of both patient and physician, in order to extend life-expectancy and to maintain a better quality of life. Within the chapters of this book, I address the types of heart conditions or cardiac effects that thyroid diseases can have on those who experience them. I also discuss the treatments in-general, that are administered to correct or to help control these potentially serious problems. It is my sincere hope that this resource helps to provide a worthy general educational resource for its readers. NOTE: This book is approximately 6,142 words in length. It is not intended as an extensive medical journal but rather contains all aspects of information on the subject that most laypersons would be seeking.
