How to treat narrowed heart blood vessels?

The main treatments for coronary artery stenosis include:

1. Daily care: For patients with mild stenosis (e.g., 50%, 60%, 70% without obvious symptoms), symptoms can be relieved through daily care. This includes maintaining a low-fat diet, ensuring adequate rest, and increasing fiber intake to prevent constipation and myocardial infarction.

2. Medication: Primarily used to relieve symptoms, prevent thrombosis, and control risk factors such as hypertension and hyperlipidemia. Commonly used medications include antiplatelet drugs (e.g., aspirin), beta-blockers, calcium channel blockers, nitrates, and statins for lipid-lowering.

3. Interventional therapy: For patients with severe vascular stenosis (e.g., greater than 70%) and clear symptoms of myocardial ischemia, interventional treatment such as coronary stent implantation can be considered. This treatment method is minimally invasive and allows for rapid recovery.

4. Surgical treatment: Primarily refers to coronary artery bypass grafting (CABG), suitable for patients with multi-vessel disease, left main coronary artery disease, or failed interventional treatment. During the surgery, autologous vessels (e.g., great saphenous vein, internal mammary artery) are used to bypass the stenotic segments and restore blood supply to the myocardium.
