Aortic coarctation has a rapid onset, usually without precursors, and symptoms are often indicative of the onset of the disease. The most common manifestation is pain. More than 80% of patients have sudden, persistent, tearing or cutting pain in the front or back of the chest, which is severe and unbearable. In addition, aortic coarctation is usually combined with high blood pressure, and there is a large difference between the blood pressure of the two upper limbs or upper and lower limbs. If the condition is serious, cardiac tamponade, hemothorax, myocardial infarction may occur, and then low blood pressure will occur. Hemorrhage from rupture of the lamina can manifest as hemorrhagic shock. Ischemia can also lead to neurological symptoms (paraplegia, incontinence, etc.), limb ischemia symptoms (limb coldness, cyanosis, etc.), visceral ischemia (low back pain, hematuria, oliguria and other renal impairment; intestinal ischemia causes intestinal necrosis; hepatic artery ischemia leads to elevated jaundice, impaired liver function, etc.). Aortic coarctation is a critical emergency, and the mortality rate is extremely high if it is not treated in time. If the above symptoms occur, you should consult a doctor immediately to avoid delaying the condition.
