Clinical manifestations during the ischemic phase of microcirculation

　　Clinical manifestations during the microcirculatory ischemic phase mainly include sweating, chest pain, and dyspnea, which require symptomatic treatment.

　　1. Sweating

　　During the microcirculatory ischemic phase, patients may experience excessive sweating, especially cold sweats. It is recommended to maintain adequate nutrition and consume more protein-rich foods such as eggs and milk.

　　2. Chest Pain

　　The main symptom of the microcirculatory ischemic phase is chest pain, typically described as a feeling of pressure, tightness, or burning sensation. The pain usually occurs behind the sternum or on the left side of the chest and may radiate to the left shoulder, left arm, neck, or jaw. Patients should immediately stop any physical activity and, under medical guidance, take metoprolol succinate extended-release tablets sublingually. Immediate hospital evaluation is strongly recommended.

　　3. Dyspnea (Shortness of Breath)

　　Due to myocardial ischemia causing impaired coordination between cardiac and pulmonary function, patients may develop dyspnea and rapid breathing. Under medical supervision, oxygen therapy can be administered to help alleviate these symptoms.

　　In addition, other symptoms may include nausea and arrhythmia. Symptoms of microcirculatory ischemia may be subtle or even absent in some cases. Individuals with a family history of heart disease or other cardiovascular risk factors should undergo regular cardiac examinations to detect potential problems early.
