When should a stent be used? —A critical guide to cardiovascular health
In recent years, cardiovascular disease has become the number one killer of global health, and cardiac stent surgery, as an important means of treating coronary heart disease, has attracted much attention. This article will combine the hot health topics on the Internet in the past 10 days to analyze for you which situations require stent surgery, and provide structured data to help you understand quickly.
1. Indications of cardiac stent surgery
Cardiac stents are mainly used to treat coronary artery stenosis or blockage. Stent surgery is usually considered in the following situations:
| Situation classification | Specific performance | clinical advice |
|---|---|---|
| acute myocardial infarction | Persistent chest pain, ST segment elevation on ECG | Urgent stent surgery is required (golden time ≤12 hours) |
| unstable angina | Chest pain and symptoms worsening when resting | Recommend surgery within 48 hours |
| stable angina | Chest pain after activity, poorly controlled with medication | Elective surgery available |
| Silent myocardial ischemia | Examination revealed severe stenosis (>70%) | Decision to be made after evaluation |
2. Correlation analysis of recent hot health topics
According to data monitoring across the entire network, the correlation between hot topics in the field of cardiovascular health and stent surgery in the past 10 days is as follows:
| hot topics | Discussion popularity | Link to stent surgery |
|---|---|---|
| The incidence of myocardial infarction in young people is rising | ★★★★★ | The number of stent surgeries for patients under 30 years old increased by 15% annually |
| How long can you live after a stent? | ★★★★ | The 10-year survival rate after surgery is 85% (standard treatment) |
| New technology for absorbable stents | ★★★ | Domestic clinical trials have been completed |
| How to choose brackets and bridges | ★★★ | Multivessel disease is more recommended for bypass grafting |
3. Danger signs to be alert to
When the following symptoms occur, you should seek medical attention immediately to evaluate whether stent surgery is needed:
1.Typical angina: Squeezing pain behind the sternum, which can radiate to the left shoulder and mandible
2.Atypical symptoms: Toothache, upper abdominal pain, dyspnea (especially for diabetic patients)
3.Decreased exercise tolerance: Chest tightness and shortness of breath after slight activity
4.Paroxysmal nocturnal dyspnea: May indicate cardiac insufficiency
4. Decision-making process for stent surgery
| Check items | diagnostic value | Suggestions for next steps |
|---|---|---|
| electrocardiogram | initial screening | Abnormalities should be further examined |
| exercise stress test | Assess for myocardial ischemia | Coronary CTA is recommended for positive cases |
| Coronary CTA | Non-invasive examination | Consider angiography if stenosis >50% |
| coronary angiography | gold standard | Determine if a stent is needed |
5. Key points of postoperative management
Things to note after stent surgery:
1.Strict medication use:Dual antimicrobial therapy (aspirin + clopidogrel) for at least 12 months
2.Regular review: Follow-up at 1, 3, 6, and 12 months after surgery
3.lifestyle adjustments: Quit smoking, control three highs, and exercise moderately
4.Be alert to the risk of bleeding: Observe gum and skin bleeding
6. Common misunderstandings about brackets
| Misunderstanding | facts |
|---|---|
| The bracket has a limited lifespan | Metal stents are effective for life, and the restenosis rate is about 5-10% |
| NMR cannot be done after stent | Most modern stents are MRI compatible |
| Stents are the ultimate cure | Risk factors still need to be controlled |
Summary: Whether a stent is needed depends on the degree of coronary artery disease and clinical symptoms. When drug control is poor or there is a risk of acute ischemia, timely stent surgery can save the myocardium and improve the prognosis. It is recommended that high-risk groups undergo regular cardiovascular assessment for early detection and early intervention.
