Any heart disease eventually may lead to grave
condition. However the progression of the disease
takes years or even decades. To follow the
progression, doctors divide the condition into several
classes. New York Heart Association uses Functional
Classification. The scale helps to find functional
ability in heart patients. Another purpose of the
scale is to estimate how patients will fare with
treatments and what volume of treatments for other
diseases they can tolerate. For example, any major
surgery even for non-heart reasons would be too
dangerous for patients with advanced heart disease.
Patients with cardiac disease, but without resulting
limitation of physical activity, when ordinary
physical activity does not cause undue fatigue,
palpitation, dyspnea, or anginal pain, are considered
Class I. That means basically that you have a heart
disease, but may do majority of the same daily routine
as a normal person.
Patients with cardiac disease resulting in slight
limitation of physical activity, when ordinary
physical activity results in fatigue, palpitation,
dyspnea or anginal pain, make Class II. They are
comfortable at rest. What is this? This is when you
have heart disease, but during physical work or
exercise you get some problems – shortness of breath,
racing heart, feeling tired and having chest pain as
in the case of angina. At rest you feel OK.
Patients with marked limitation of physical activity
become Class III. Those people are comfortable at
rest. However, less than ordinary activity causes
fatigue, palpitation, dyspnea, or anginal pain.
Eventually some patients with cardiac disease progress
toward inability to carry on any physical activity
without discomfort. That would be Class IV. Symptoms
of heart failure or of the anginal syndrome (chest
pain suggesting heart disease) may happen even at
rest. Any physical activity makes discomfort even
worse. | | Author: | Aleksandr Kavokin, MD, PhD | | System: | Heart | | Subject: | Failure | | Abstract: | New York Heart Association uses Functional
