If chest tightness occurs after waking up, it may be angina attack or high blood pressure after waking up in the morning, which triggers discomfort in the anterior region of the heart. You can first take sublingual rescue pills or compound danshen drip pills, and if necessary, you can check the dynamic electrocardiogram, cardiac ultrasound and chest X-ray examination. There may also be insomnia, dreaminess and sleep quality problems at night, and precordial discomfort after waking up in the morning, which may be related to vegetative dysfunction or cardiac neurosis. If necessary, drugs such as coronary heart danshen drip pills and Xinyue capsules can also be taken to help better relieve the discomfort. Post-menopausal women or elderly patients may undergo a coronary CT scan to help identify the presence of coronary artery disease.
