Older people have a binding sensation in the whole chest and back when taking a deep breath may be cardiovascular disease, acute pleurisy, acute pneumonia, tension pneumothorax, etc., and should consult the doctor in time to find out the cause of the disease. 1. Cardiovascular disease: usually caused by coronary artery ischemia, spasm, contraction leading to tightness in the chest and back. The coronary arteries of the heart are divided into three branches, namely, the left anterior descending branch, the left circumflex branch and the right coronary artery. When there is obvious spasm, contracture, ischemia and stenosis in the right coronary artery, there will be a binding sensation in the whole chest and back when taking a deep breath. 2. Acute pleurisy, acute pneumonia: the symptom of a binding sensation in the whole chest and back when taking a deep breath, accompanied by fever, cough and other symptoms will also occur. 3. Tension pneumothorax: the pressure in the chest cavity increases when taking a deep breath due to the increased pressure inside the chest, resulting in a binding sensation in the whole front and back of the chest. This symptom alone is not enough to diagnose the disease, and may be caused by other factors. It is recommended that the patient consult a doctor in time to clarify the cause of the disease and give targeted treatment.
