Introduction

Stent refers to stent implantation. Generally, patients with coronary artery blockage exceeding 70% require stent implantation. The coronary arteries are the main blood vessels supplying the heart; if blocked, they can lead to serious conditions such as myocardial ischemia, angina pectoris, and myocardial infarction. Stent implantation is a common treatment method for coronary artery blockages.

Stent usually refers to stent implantation. In general, patients with coronary artery blockage exceeding 70% require stent implantation. Details are as follows:

The coronary arteries are the main blood vessels supplying the heart. Blockage in these arteries can lead to serious conditions such as myocardial ischemia, angina pectoris, and myocardial infarction. Stent implantation is a common treatment for coronary artery blockage. Typically, patients with blockages exceeding 70% are recommended for stent implantation. This procedure involves using a catheter to place a stent inside the coronary artery to expand narrowed or blocked vessels and restore normal blood flow.

It should be noted that although stent implantation is a common treatment for coronary artery blockage, it does carry certain risks and potential complications, such as bleeding, thrombosis, and vascular injury. Patients are advised to consult their doctor in detail before surgery to determine the most suitable treatment plan for their individual condition.

Can coronary artery stenosis heal on its own?

In general, coronary artery stenosis cannot heal spontaneously. The detailed analysis is as follows: Coronary artery stenosis is caused by various factors such as coronary atherosclerosis, which in turn leads to myocardial ischemia and necrosis, ultimately resulting in angina pectoris and myocardial infarction. Conditions causing coronary artery stenosis—including coronary atherosclerosis, coronary artery spasm, myocardial bridge, and arteritis—cannot resolve on their own.

What are the hazards of complete occlusion of the right coronary artery?

The right coronary artery is one of the major arteries supplying blood to the human heart. Complete occlusion of this artery can significantly impair cardiac function. In general, complications of complete occlusion of the right coronary artery include acute myocardial infarction, arrhythmias, and heart failure. Besides these conditions, sudden cardiac death may also occur unexpectedly.
