High lipoprotein a may present with symptoms such as chest tightness, dizziness or heart discomfort. 1. Chest tightness: when lipoprotein a is high, lipid metabolism is abnormal, thus causing chest tightness and even difficulty in breathing. 2. Dizziness: Due to high lipoprotein a, the endothelium of blood vessels is damaged, resulting in atherosclerosis, leading to insufficient blood and oxygen supply to the brain and dizziness symptoms. 3. Myocardial discomfort: due to high lipoprotein a easily lead to arteriosclerosis, resulting in myocardial ischemia, acute myocardial infarction, sudden severe chest pain, dyspnea, severe shock and other symptoms. It is recommended to pay attention to dietary habits in daily life, carry out some physical exercise, such as the emergence of symptoms of discomfort in a timely manner to the hospital to find out the cause of the disease.
