If you experience chest tightness after waking up, it may be caused by angina pectoris attack or high blood pressure after waking up in the morning, which may lead to discomfort in the precordial region. You can start with sublingual heart pills or compound salvia drops, and if necessary, you can check the ambulatory electrocardiogram, cardiac ultrasound and chest X-ray. It is also possible that insomnia, excessive dreaming, and sleep quality problems may occur at night, and precordial discomfort may occur after waking up in the morning, which may be related to disturbance of plant nervous function or cardiac neurosis. If necessary, you can also take such medications as Coronary Heart Danshin Drops and Heartjoy Capsules to help relieve the discomfort better. Postmenopausal women or elderly patients can have a coronary CT scan to help clarify the presence of coronary artery disease.
