The symptoms of cardiovascular blockage are various, mainly including circulatory symptoms, respiratory symptoms, local pain symptoms and systemic symptoms. 1. Circulatory system symptoms: patients with cardiovascular blockage will suffer from insufficient blood supply due to decreased heart function, resulting in circulatory system symptoms, such as chest tightness, palpitations (rapid heartbeat, often accompanied by panic), angina and chest pain, etc. Common symptoms include chest tightness, chest tightness and shortness of breath. 2. Respiratory symptoms: patients with cardiovascular blockage will have respiratory symptoms such as dyspnea, chest tightness and shortness of breath because cardiovascular blockage affects the pulmonary artery and then affects the lungs, thus producing respiratory symptoms. 3. Localized pain symptoms: cardiovascular blockage can also cause pain in other parts of the body due to referred pain, such as back pain, left shoulder pain and left arm pain and other localized pain manifestations. 4. Systemic symptoms: patients may also experience systemic symptoms such as dizziness, sweating and fatigue. Patients with cardiovascular blockage need to go to the hospital in time and follow the doctor’s instructions.
