Current through Register Vol. 49, No. 13, September 23, 2024
Subpart
1.
General.
For permanent partial impairment due to organic heart
disease, the disability of the whole body is as provided in subparts
2 and
3.
Subp. 2.
Organic heart disease.
Signs or symptoms of organic heart disease are documented,
there is anatomic loss or alteration as demonstrated by angiography or nuclear
medicine study.
Objective evidence of myocardial infarction is documented,
that is, cardiac enzymes or EKG changes:
A. uncomplicated, five percent;
B. with persistent abnormal cardiac function,
the rating is as provided in subpart
3 and combined as described
in part
5223.0300, subpart
3, item E, with five
percent.
Subp. 3.
Exercise limitation.
Signs or symptoms of organic heart disease are documented,
there is anatomic loss or alteration as demonstrated on angiography or nuclear
medicine study. The percentage of disability is determined by the loss of
functional exercise capacity as measured by Bruce protocol exercise stress test
or nuclear isotope exercise study.
A.
Able to exercise to a VO2 max greater than 25 milliliters per kilogram each
minute, zero percent.
B. Exercise
stress test or exercise study stopped at or VO2 max of 25 milliliters per
kilogram each minute but after 22 milliliters per kilogram each minute due to
development of diagnostic ischemic changes, arrhythmia, pathological change in
blood pressure or blood pressure-heart rate product, or the development of
objective clinical signs of cardiac dysfunction, or dyspnea with rales on
auscultation, or chest pain relieved by nitroglycerin, ten percent.
C. Exercise stress test or exercise study
stopped at or before VO2 max of 22 milliliters per kilogram each minute but
after 19 milliliters per kilogram each minute due to development of diagnostic
ischemic changes, arrhythmia, pathological change in blood pressure or blood
pressure-heart rate product, or the development of objective clinical signs of
cardiac dysfunction, or dyspnea with rales on auscultation, or chest pain
relieved by nitroglycerin, 25 percent.
D. Exercise stress test or exercise study
stopped at or before VO2 max 19 milliliters per kilogram each minute but after
15 milliliters per kilogram each minute due to development of diagnostic
ischemic changes, arrhythmia, pathological change in blood pressure or blood
pressure-heart rate product, or the development of objective clinical signs of
cardiac dysfunction, or dyspnea with rales on auscultation, or chest pain
relieved by nitroglycerin, 50 percent.
E. Exercise stress test or exercise study
stopped at or before VO2 max of 15 milliliters per kilogram each minute but
after seven milliliters per kilogram each minute due to development of
diagnostic ischemic changes, arrhythmia, pathological change in blood pressure
or blood pressure-heart rate product, or the development of objective clinical
injury of cardiac dysfunction, or dyspnea with rales on auscultation, or chest
pain relieved by nitroglycerin, 75 percent.
F. Exercise stress test or exercise study
stopped before a VO2 max of seven milliliters per kilogram each minute due to
development of diagnostic ischemic changes, arrhythmia, pathological change in
blood pressure or blood pressure-heart rate product, or the development of
objective clinical signs of cardiac dysfunction, or dyspnea with rales on
auscultation, or chest pain relieved by nitroglycerin, 95 percent.
G. Diagnostic ischemic changes at rest, 95
percent.
