You may not have received ongoing treatment or have an ongoing relationship with the medical community despite the existence of a severe impairment(s). What if you have not received ongoing medical treatment?Ī. The record will provide us with information on your functional status over an extended period of time and show whether your ability to function is improving, worsening, or unchanging.ģ. It should also include your response to this medical management, as well as information about the nature and severity of your impairment. Whenever there is evidence of such treatment, your longitudinal clinical record should include a description of the ongoing management and evaluation provided by your treating or other medical source. If you have a listing-level impairment, you probably will have received medically prescribed treatment. Why is a longitudinal clinical record important? We will usually need a longitudinal clinical record to assess the severity and expected duration of your impairment(s). A longitudinal clinical record covering a period of not less than 3 months of observations and treatment is usually necessary, unless we can make a determination or decision based on the current evidence.Ģ. What basic documentation do we need? We need sufficiently detailed reports of history, physical examinations, laboratory studies, and any prescribed treatment and response to allow us to assess the severity and duration of your cardiovascular impairment. Uncontrolled means the impairment does not adequately respond to standard prescribed medical treatment.ġ. A consecutive 12-month period means a period of 12 consecutive months, all or part of which must occur within the period we are considering in connection with an application or continuing disability review.į. Appropriate medically acceptable imaging means that the technique used is the proper one to evaluate and diagnose the impairment and is commonly recognized as accurate for assessing the cited finding.Į. Recurrent means that the longitudinal clinical record shows that, within a consecutive 12-month period, the finding(s) occurs at least three times, with intervening periods of improvement of sufficient duration that it is clear that separate events are involved.ĭ. Persistent means that the longitudinal clinical record shows that, with few exceptions, the required finding(s) has been present, or is expected to be present, for a continuous period of at least 12 months, such that a pattern of continuing severity is established.Ĭ. We use the abbreviation “MC” throughout this section to designate a medical consultant.ī. This term does not include medical sources who provide consultative examinations for us. Medical consultant is an individual defined in §§ 404.1616(a) and 416.1016(a). What do the following terms or phrases mean in these listings?Ī. What do we consider in evaluating cardiovascular impairments? The listings in this section describe cardiovascular impairments based on symptoms, signs, laboratory findings, response to a regimen of prescribed treatment, and functional limitations.ģ. We will evaluate peripheral vascular disease under 4.11 or 4.12 and impairments of another body system(s)under the listings for that body system(s).Ģ. The central nervous system, the eyes, the kidneys, and other organs. Disorders of the veins or arteries (for example, obstruction, rupture, or aneurysm) may cause impairments of the lower extremities (peripheral vascular disease), (iv) Central cyanosis due to right-to-left shunt, reduced oxygen concentration in the arterial blood, or pulmonary vascular disease.Ĭ. (iii) Syncope, or near syncope, due to inadequate cerebral perfusion from any cardiac cause, such as obstruction of flow or disturbance in rhythm or conduction resulting in inadequate cardiac output. (ii) Discomfort or pain due to myocardial ischemia, with or without necrosis of heart muscle. (i) Chronic heart failure or ventricular dysfunction. Cardiovascular impairment results from one or more of four consequences of heart disease: The disorder can be congenital or acquired.ī. We mean any disorder that affects the proper functioning of the heart or the circulatory system (that is, arteries, veins, capillaries, and the lymphatic drainage). What do we mean by a cardiovascular impairment?Ī.
