Fainting episodes
Due to the sharp and stabbing pain caused by angina, many patients might experience fainting episodes during this condition. Basically, the narrowed blood vessels lead to the lack of oxygen demand and supply to other parts of your body. As a result, you will suffer from this condition. In most cases, this symptom can be worsened by emotional or physical stresses and is alleviated by rest. If left untreated for a long period, it might cause more serious issues that can negatively affect your cardiovascular system, especially your heart. [3]
