What causes intermittent stabbing pain in the heart or chest area, and what should be done about it?

Episodic sharp chest pain may be caused by lack of sleep, nervous system disorders, angina pectoris, etc. Long-term熬夜 (staying up late) without sufficient rest can overload the heart, leading to intermittent sharp chest pain; it is recommended to get adequate rest and maintain sufficient sleep. When the nervous system becomes imbalanced or disordered, it may cause discomfort in the heart, resulting in episodic sharp pain. It is advisable to take medication under a doctor's guidance. Patients with angina pectoris may experience symptom flare-ups, including sharp pain, during physical exertion or stressful situations. Medications such as beta-blockers (e.g., metoprolol tartrate) may be used as directed by a physician.
