Introduction
Under normal circumstances, myocardial ischemia generally does not cause chest tightness throughout the entire day. It is recommended to seek timely medical attention and undergo symptomatic treatment under a doctor's guidance after identifying the underlying cause. To avoid delaying diagnosis or worsening the condition, it is advised to undergo examinations such as electrocardiogram (ECG) and coronary angiography under the guidance of a specialist. In terms of daily life, attention should be paid to quitting smoking, limiting alcohol consumption, controlling body weight, and engaging in regular physical activity.
Generally, myocardial ischemia does not usually cause chest tightness throughout the entire day. It is recommended to seek timely medical attention, identify the underlying cause, and then receive symptomatic treatment under the guidance of a physician. Detailed analysis is as follows:
Myocardial ischemia refers to a pathological condition in which reduced blood perfusion to the heart leads to decreased oxygen supply and abnormal energy metabolism of the myocardium, thereby preventing the heart from functioning normally. Most symptoms are episodic in nature and typically manifest as chest pressure, heaviness, tightness, or pain, which may radiate to the left shoulder, left arm, neck, or jaw. The discomfort often occurs during physical exertion, emotional excitement, after a heavy meal, or in cold weather, lasts for 3 to 5 minutes, and can be gradually relieved by rest or sublingual administration of nitroglycerin.
To avoid delaying diagnosis or worsening the condition, it is recommended to undergo examinations such as electrocardiogram (ECG) and coronary angiography under the guidance of a specialist physician to determine the exact cause. Regarding daily lifestyle, it is important to quit smoking, limit alcohol consumption, maintain a healthy weight, exercise regularly, and avoid a high-fat, high-salt diet to reduce the risk of myocardial ischemia.
