Symptoms such as chest pain still present after stenting are very common in clinical practice, but one must be vigilant and we need to know how long after stenting the symptoms appear as a key condition when determining the severity of this problem! Mr. Wang, 56, had a heart stent surgery in early 2016 due to myocardial infarction, and everything went well with the surgery. Recently Mr. Wang suddenly felt weakness, panic and chest tightness so much that he had to be admitted to the hospital again, and the diagnosis showed: coronary heart disease, old myocardial infarction, arrhythmia, ventricular tachycardia, and he is still under observation and treatment in the monitoring room, this time mainly ventricular tachycardia, which means that the heart is not beating normally and can be life-threatening. Patients with heart attack will have their chest tightness and chest pain symptoms resolved after receiving stents for revascularization, but the surgery only solves the problem of a small section of blood vessels, and if the post-operative treatment and recurrence prevention are not done well, it is likely that a situation like Mr. Wang’s will occur. Stent implantation for coronary heart disease, the effect is immediate? Many patients think that the disease is cured when all the symptoms of coronary heart disease disappear. In fact, the full name of coronary artery disease is coronary atherosclerosis, that is to say, people with coronary heart disease, the heart of multiple coronary arteries are narrowed, only the degree of narrowing is different, some lighter, some more serious, and stents can only solve the highest degree of stenosis, not to mention the narrowing of other vessels, even if the stented vessels may still appear restenosis. The following reasons can be considered for the discomfort of chest tightness and panic after stenting of coronary stenosis: a. It occurs when multiple stents or long stents are placed and the outer membrane of the vessel is stretched, and the patient may show distension and chest tightness, mostly at rest, with no obvious changes in the electrocardiogram. Second, the patient’s condition is more serious, and there are multiple vascular blockages throughout the body. Although the stent restores part of the blood flow, there are still objective facts such as myocardial ischemia. Now, long-term ambulation, low head playing cell phone and other behaviors lead to cervical vertebrae tilting forward, thus driving the thoracic vertebrae also concave inward, the nerves near the thoracic vertebrae will be stuck, resulting in disorder of the nerves around the vertebrae, making the blood vessels around the vertebrae spasmodically contracted, and the performance of blood supply is not available, thus appearing chest tightness and panic. Therefore, if a patient has symptoms such as chest tightness and panic after cardiac stenting, then it is necessary to find the cause as soon as possible and treat the symptoms to avoid irreversible consequences.
