The diagnosis of heart attack is suspected when back pain is accompanied by the manifestations of heart attack, which can be confirmed by electrocardiogram and examination of cardiac markers.
1. Infarction manifestations: chest pain after minor activities, commonly in the precordial region, or resting pain or nocturnal angina pectoris, chest pain may radiate to the left shoulder, back and other parts of the body, and cannot be relieved by regular rest and nitroglycerin.
2. Electrocardiogram (ECG): Most patients with heart attack have typical ischemic changes on ECG during the onset of chest pain, which are manifested as transient ST-segment (elevated or depressed) and T-wave (flattened or inverted) changes, among which the dynamic change of ST-segment is the manifestation of severe coronary artery disease, which may lead to acute myocardial infarction or sudden death.
3. Cardiac marker examination: cardiac troponin is more sensitive to the diagnosis of myocardial injury, in addition, cardiac enzymes and their isoenzymes also have certain diagnostic significance.
Back pain may also be muscle strain, neuralgia and spinal disease. Patients should go to regular hospitals in time to get a clear diagnosis and active treatment.
