What are Asymptomatic Patients?
People may be suffering from Coronary Artery Disease without being aware of it, because many of them may not have any typical clinical symptoms like chest pain or may have atypical symptoms like chest tightness or breathlessness or gaseous discomfort. These are cases which can go undetected for a long time. For many of these cases, heart attack may be first sign of Coronary Artery Disease and many of such patients never reach the hospital.
