Lightheadedness
In some cases, patients may feel dizzy and lightheaded, especially in elderly patients and if they have an underlying condition. In severe cases of lightheadedness, patients may also lose consciousness for a few seconds, which is a symptom called syncope. Lightheadedness is common in many different diseases, not necessarily related to the cardiovascular system, and it is also common in angina pectoris, which is why a physician should examine this symptom carefully to fully understand and reach the final diagnosis.
