How to detect coronary heart disease
Coronary heart disease (coronary atherosclerotic heart disease) is a common cardiovascular disease, and early diagnosis and treatment are critical to preventing serious complications. The following is a detailed introduction to coronary heart disease examination methods, combined with the hot topics and hot content on the entire network in the past 10 days, to provide you with structured data and analysis.
1. Common examination methods for coronary heart disease
| Check method | Check content | Applicable people | Advantages and Disadvantages |
|---|---|---|---|
| Electrocardiogram (ECG) | Record electrical activity of the heart to detect arrhythmia or myocardial ischemia | Patients with suspected angina or myocardial infarction | Fast and non-invasive, but static ECG may miss diagnosis |
| exercise stress test | Monitor ECG changes during exercise | Those at risk for coronary heart disease but with normal resting ECG | Can simulate cardiac load, but there are certain risks |
| coronary angiography | Contrast material is injected through the catheter to show narrowing of the coronary arteries | Suspected patients with severe coronary heart disease | Gold standard, but invasive and expensive |
| Cardiac CT Angiography (CTA) | Using CT technology to observe the structure of coronary arteries | Screening for low- to moderate-risk groups | Non-invasive, fast, but radiation exposure |
| Cardiac Magnetic Resonance Imaging (MRI) | Assess heart structure and function | Patients who require detailed evaluation of myocardial viability | No radiation, but examination time is long |
2. The relationship between recent hot topics and coronary heart disease examinations
1.Application of artificial intelligence in diagnosis of coronary heart disease: Recent studies have shown that AI algorithms can improve the accuracy of early diagnosis of coronary heart disease by analyzing electrocardiogram and imaging data.
2.Progress in non-invasive examination technology: New biomarkers and portable monitoring devices have become hot spots, such as high-sensitivity troponin detection and wearable ECG monitoring devices.
3.Updated guidelines for coronary heart disease screening: The American Heart Association (AHA) recently discussed screening recommendations for asymptomatic people, which has attracted widespread attention.
3. Precautions for coronary heart disease examination
1.Preparation before inspection: Some examinations require fasting or discontinuation of certain medications, and doctor’s advice is required.
2.Risk notification: Invasive examinations require signing of an informed consent form to understand potential complications.
3.Interpretation of results: The examination results need to be comprehensively judged by professional doctors combined with clinical symptoms to avoid self-diagnosis.
4. Examination recommendations for different groups of people
| Crowd classification | Recommended inspection | Check frequency |
|---|---|---|
| High-risk groups (smoking, high blood pressure, diabetes, etc.) | Exercise stress test + coronary CTA | 1 time per year |
| Medium risk group | Resting ECG + blood lipid test | Once every 2-3 years |
| low risk group | Routine physical examination | Once every 5 years |
| Confirmed patients | Coronary angiography + regular review | Determine according to the condition |
5. Prevention and early detection of coronary heart disease
1.lifestyle intervention: Recent studies highlight that a Mediterranean diet and regular exercise can reduce the risk of coronary heart disease by up to 30%.
2.Regular physical examination: People over 40 years old are recommended to undergo annual cardiovascular risk assessment.
3.Symptom alert: Chest tightness, shortness of breath, fatigue and other atypical symptoms may also be signs of coronary heart disease.
4.New technology application: Pay attention to innovative technologies such as AI-assisted diagnosis and remote ECG monitoring.
Through the above examination methods and preventive measures, coronary heart disease can be detected early, intervened promptly, and the prognosis can be significantly improved. It is recommended that people with risk factors for coronary heart disease conduct regular cardiovascular health assessments and choose appropriate examination options under the guidance of a doctor.
