The peak time for heart attacks is in the early morning hours.
Generally speaking, "heart attack" refers to acute myocardial infarction, which most frequently occurs between 3:00 and 5:00 AM. The specific analysis is as follows:
Acute myocardial infarction can occur at any time of the day, but the likelihood is higher between 3:00 and 5:00 AM. During this period, the patient's autonomic nervous system is predominantly under sympathetic control. Sympathetic activation may lead to relative coronary artery constriction and abnormal plaque rupture. After an acute myocardial infarction occurs, patients should promptly seek treatment at a formal chest pain center. Treatment may include thrombolytic therapy or percutaneous coronary intervention as directed by a physician. Individuals at risk should take preventive measures in daily life: avoid intense physical activity upon waking, rise slowly from bed, avoid emotional excitement, and refrain from eating large meals in the morning. Patients may take medications such as metoprolol succinate extended-release tablets or bisoprolol hydrochlorothiazide tablets as prescribed.
If patients experience any symptoms of discomfort, they are advised to seek immediate medical attention to avoid delays in diagnosis and treatment.
