First, they are reluctant to do surgery for a long time, which makes the heart ischemic for a long time and the heart function is not complete, resulting in untimely treatment or missing the best time for treatment. Secondly, they think that everything will be fine after the heart stent is placed and the blood vessels can be kept open forever, so they relax freely in terms of diet, medication, smoking and drinking, which leads to the recurrence of the disease. Thirdly, they are overly afraid of coronary heart disease and blindly ask doctors to place vascular stents even though they do not need cardiac interventional surgery. Interventional cardiac surgery has its corresponding indications, and treatment should be selected scientifically under the guidance of a doctor according to the condition.
