Introduction
Mild angina or myocardial ischemia, acute myocardial infarction, cardiovascular blockage, and similar symptoms require stent placement surgery. Additionally, stent surgery is also needed for refractory angina, severe coronary artery stenosis identified by coronary angiography, and symptoms such as chest tightness and painful sensations. Patients should avoid high-fat diets. Those with concomitant hypertension or diabetes should also restrict salt and sugar intake.
Mild angina or myocardial ischemia, acute myocardial infarction, and cardiovascular blockages are conditions that may require stent placement.
1. Patients with mild angina or myocardial ischemia who, through treadmill testing or 24-hour Holter monitoring, are found to have significant ischemic changes or severe lesions may be considered for stent treatment.
2. Acute Myocardial Infarction
Acute myocardial infarction occurs when a sudden blood clot forms in the coronary artery, blocking blood flow and causing heart muscle necrosis. Most clots develop on the basis of atherosclerotic plaques, which trigger thrombus formation. Once the clot is removed, significant atherosclerotic plaque often remains, necessitating stent implantation. The stent supports the narrowed segment, preventing re-formation of clots at the same site and allowing blood to flow smoothly through the constricted area, thereby supplying oxygen to the heart.
3. Cardiovascular Blockage
If the cardiovascular system is severely blocked, leading to inadequate blood supply, coronary stenting or bypass surgery may be considered.
In addition, stent placement may also be needed for refractory angina, severe coronary artery narrowing confirmed by angiography, or symptoms such as chest tightness and pain. It is important to avoid high-fat diets. Patients with comorbidities such as hypertension and diabetes should also restrict their intake of salt and sugar.
