Chest tightness after exertion

Introduction Cardiac chest tightness: characterized by chest tightness after exhaustion, difficulty breathing, or paroxysmal dyspnea at night, patients can wake up from sleep, see pulmonary congestion, heart failure, chest tightness can also be coronary heart disease A manifestation of angina during blood. Angina pectoris is a clinical syndrome characterized by episodes of chest pain or chest discomfort caused by acute coronary insufficiency, acute myocardial ischemia, and hypoxia. It is characterized by frontal chest paroxysmal and crushing pain, which may be accompanied by other symptoms. The pain is mainly located in the posterior part of the sternum and can be radiated to the anterior and left upper limbs. Labor or emotional agitation often occurs, and each episode lasts for 3 to 5 minutes. It can be taken once a day, or several times a day, after a break or disappearing with a nitrate ester preparation.

Cause

Long hours of work are the main reason. Mostly atherosclerosis, valvular disease (especially surgical aortic valve disease) can also be seen. Hypertrophic cardiomyopathy, uncontrolled hypertension, hyperthyroidism or severe anemia, normal coronary arteries may also be due to coronary artery spasm or endothelial dysfunction and other reasons, unstable angina, leading to fatigue and chest tightness.

Dynamic electrocardiogram (Holter monitoring) ECG

1, aortic dissection: CT scan can confirm the diagnosis.

2, pulmonary embolism: specific electrocardiogram to help diagnose.

3, can do ECG examination, ST segment changes can occur.

4, other examinations, X-ray examination, two-dimensional ultrasound ECG with spiral CT and nuclear magnetic resonance.

Differential diagnosis

Differential diagnosis of chest tightness after exertion:

1, cardiogenic chest tightness: characterized by chest tightness after exhaustion, difficulty breathing, or paroxysmal dyspnea at night, patients can wake up from sleep, seen in patients with heart disease, pulmonary congestion, cardiac insufficiency. Chest tightness can also be coronary heart disease A manifestation of angina during myocardial ischemia.

2, pulmonary thoracic: seen in bronchial asthma, pleural effusion, spontaneous pneumothorax, pulmonary fibrosis.

3, chest function caused by neurological function: common in cardiovascular dysfunction. The patient feels chest tightness, shortness of breath, subjective feeling of lack of air, poor breathing, often sigh-like breathing, self-satisfaction after long gas; sometimes accompanied by palpitations, tingling in the precordial area, and fatigue, dizziness, unclear mind, Neurological symptoms such as anxiety, sweating, and insomnia. The disease sometimes resembles coronary heart disease and angina pectoris, but electrocardiogram, cardiac B-ultrasound, and other tests have no organic lesions.
