6. Fatigue and feeling of unwellness
Fatigue is a common complaint in patients suffering from heart conditions. The heart pumps blood carrying oxygen and nutrients to the body, and when this physiological process is impaired, the muscles fail to function properly because they need high and constant supply of oxygen and glucose. In the case of angina, the resulting arrhythmia and the inability of the heart to deliver the required blood to the muscles will lead to easy fatiguability and general feeling of weakness.
