For example, a diabetic patient with severe coronary artery disease may have little or no symptoms. On the other hand, another patient with milder disease may be incapacitated by recurring chest pain.
Similarly, another patient with heart failure or "weakened heart muscle" may be able to lead a relatively normal life despite having severe disease because the heart has had a chance to compensate or adapt to the disease. In contrast, another patient with milder disease may have severe shortness of breath that may occur during usual daily activities or even at rest.
