Sedentary Work Exerting up to 10 pounds (4.5 kg) of force occasionally and/or a negligible amount of force frequently or constantly to lift, carry, push, pull, or otherwise move objects, including the human body. Sedentary work involves sitting most of the time, but may involve walking or standing for brief periods of time. Jobs are sedentary if walking and standing are required only occasionally and other sedentary criteria are met.

Light Work Exerting up to 20 pounds (9.1 kg) of force occasionally and/or up to 10 pounds (4.5 kg) of force frequently, and/or negligible amount of force constantly to move objects. Physical demand requirements are in excess of those for Sedentary Work. Light Work usually requires walking or standing to a significant degree. However, if the use of the arm and/or leg controls requires exertion of forces greater than that for Sedentary Work and the worker sits most the time, the job is rated Light Work.

Medium Work Exerting up to 50 (22.7 kg) pounds of force occasionally, and/or up to 25 pounds (11.3 kg) of force frequently, and/or up to 10 pounds (4.5 kg) of forces constantly to move objects.

Heavy Work Exerting up to 100 pounds (45.4 kg) of force occasionally, and/or up to 50 pounds (22.7 kg) of force frequently, and/or in excess of 20 pounds (9.1 kg) of force constantly to move objects.

Very Heavy Work Exerting in excess of 100 pounds (45.4 kg) of force occasionally, and/or in excess of 50 pounds (22.7 kg) of force frequently, and/or in excess of 20 pounds (9.1 kg) of force constantly to move objects.

Job Classification

In most duration tables, five job classifications are displayed. These job classifications are based on the amount of physical effort required to perform the work. The classifications correspond to the Strength Factor classifications described in the United States Department of Labor's Dictionary of Occupational Titles. The following definitions are quoted directly from that publication.

Sedentary Work Exerting up to 10 pounds (4.5 kg) of force occasionally and/or a negligible amount of force frequently or constantly to lift, carry, push, pull, or otherwise move objects, including the human body.

Ability to work depends on the outcome of treatment (relief of symptoms, improved ventricular function), the severity of residual symptoms, the presence or absence of other medical conditions, and the requirements of the individual's job.

Prognosis

Once coronary atherosclerosis develops, it must be managed for life. The risk of subsequent cardiac events or disruption of the general circulation depends on control of the disease through lifestyle changes and medication. These changes can prevent disease progression by reducing future deposits of cholesterol and plaque in the coronary arteries. Statins, which are sometimes prescribed with a selective cholesterol absorption inhibitor, can dramatically reduce plaque already present, raise levels of HDL cholesterol, and possibly reduce the inflammatory process believed to be responsible for the development and progression of coronary atherosclerosis. Medication has the additional effect of softening plaque deposits, making them less likely to break away from the artery wall and block blood vessels within the heart.

Surgical procedures, such as coronary angioplasty and bypass surgery, successfully improve blood flow to the heart and decrease risk of myocardial infarction and sudden cardiac death for some subgroups of patients, but the risk of blockage by future plaque deposits remains. Thus lifelong adherence to risk factor reduction is necessary.
