According to section 4.00 of the SSA Blue Book, a cardiovascular condition is any disorder that affects the proper functioning of the heart or circulatory system. The Blue Book lists several heart conditions that may be more likely to qualify for SSD benefits, including:
Chronic heart failure
Ischemic heart disease
Recurrent arrhythmias
Symptomatic congenital heart disease
Heart transplant
Chronic venous insufficiency
Peripheral arterial disease
As with other disabilities, your heart problem must prevent you from working for a minimum of one year. Your disability symptoms need to fit the criteria for one of the heart conditions listed in the Blue Book.
