Heart Disorders describe a range of heart-related conditions. Cardiac disorders include diseases of the blood vessels, such as coronary artery disorders; heart rhythm issues (arrhythmias); and heart defects with which you were born (congenital heart defects). This usually refers to conditions involving narrowed or blocked blood vessels which may result in heart failure, chest pain (angina), or stroke. Certain diseases of the heart, such as those affecting the muscle, valves, or rhythm of your heart, are also considered types of heart disease. It is possible to prevent or treat heart diseases at an early stage and also with healthy lifestyle choices.
