What diseases can be detected by ESR (Erythrocyte Sedimentation Rate)?

Generally speaking, ESR refers to the erythrocyte sedimentation rate test. This test may detect diseases such as bacterial infections, angina pectoris, myocardial infarction, pulmonary embolism, and systemic lupus erythematosus. If discomfort symptoms occur, it is recommended to seek timely medical consultation and receive symptomatic treatment under the guidance of a qualified physician. Detailed analysis is as follows:

1. Bacterial Infection

Bacterial infection is an acute systemic infection caused by pathogenic bacteria entering the bloodstream and producing toxins. Patients may experience symptoms such as fever and chills. During bacterial infection, the inflammatory response in the body intensifies, significantly increasing the erythrocyte sedimentation rate.

2. Angina Pectoris

Angina pectoris is a condition caused by insufficient coronary artery blood supply, leading to myocardial ischemia and hypoxia. Patients may experience symptoms such as chest pain and chest tightness. In angina, inadequate coronary blood supply stimulates the production of inflammatory factors, increases blood viscosity, promotes red blood cell aggregation, and accelerates the erythrocyte sedimentation rate.

3. Myocardial Infarction

Myocardial infarction is a disease caused by coronary artery insufficiency leading to myocardial ischemia and necrosis. Patients typically experience symptoms such as chest pain and shortness of breath. During a myocardial infarction, ischemia and necrosis of the myocardium release large amounts of inflammatory factors, resulting in an elevated erythrocyte sedimentation rate.

4. Pulmonary Embolism

Pulmonary embolism is a disease caused by substances such as blood clots entering the pulmonary artery, resulting in pulmonary tissue ischemia and hypoxia. Patients may experience symptoms including dyspnea, chest pain, and hemoptysis. Pulmonary embolism can trigger an inflammatory response, accelerating the erythrocyte sedimentation rate.

5. Systemic Lupus Erythematosus (SLE)

Systemic lupus erythematosus is an autoimmune disease affecting multiple systems, such as the skin, joints, and kidneys. During the active phase of SLE, the inflammatory response within the body is heightened, leading to an increased erythrocyte sedimentation rate.

Maintaining good lifestyle and dietary habits in daily life can enhance immune function and help prevent the occurrence of diseases.
