Consequences of not being able to place a stent for cardiovascular blockage

Cardiovascular blockage can easily lead to myocardial infarction. If stent placement surgery is not possible, coronary artery bypass surgery may be an alternative; otherwise, the risk of developing myocardial infarction may increase.

Blockages in the heart's blood vessels are prone to cause myocardial infarction. Stent placement can reopen blocked vessels and improve cardiac blood circulation. Typically, when a blood vessel is blocked by more than 75%, stent surgery is recommended. Without stent placement, there is a high risk of myocardial ischemia, inadequate blood supply, myocardial infarction, or even cardiac arrest. Common risks associated with coronary stent intervention include allergic reactions in patients sensitive to contrast agents used during the procedure, as well as potential adverse effects on kidney function. In rare cases, complications such as blood vessel rupture or cardiac tamponade during the procedure may trigger arrhythmias or lead to cardiac arrest.

If a patient’s medical condition makes stent surgery unsuitable, those with mild symptoms may opt for conservative treatment, taking medications such as enteric-coated aspirin, atorvastatin calcium tablets, and Danshen dripping pills under a doctor’s guidance. For patients with severe symptoms who cannot undergo stent placement, coronary artery bypass surgery at a major hospital may be considered.

In daily life, appropriate exercise can help improve overall health. Avoiding late nights and emotional outbursts may also help reduce the occurrence of cardiovascular blockages.
