Clinical Types of Coronary Heart Disease

Today, many people frequently stay up late for work or study, which exerts significant negative effects on the body—reducing immune function and disrupting endocrine balance. Excessive workloads also place undue stress on the heart, commonly leading to coronary artery disease (CAD). So, what are the clinical types of CAD?

Clinical Types of Coronary Artery Disease

The five clinical types of CAD are as follows: 1. **Silent myocardial ischemia**: Patients typically exhibit no symptoms; most cases are detected incidentally during routine physical examinations or electrocardiograms (ECGs). 2. **Ischemic cardiomyopathy**: Caused by long-standing CAD and chronic myocardial hypoperfusion, resulting in diminished cardiac contractility and cardiac enlargement. Color Doppler echocardiography aids in diagnosis. 3. **Angina pectoris**: Characterized by recurrent chest pain (typically substernal or precordial), lasting several minutes and usually relieved by rest. 4. **Acute myocardial infarction (AMI)**: Often presents with persistent chest pain or pressure, dyspnea, or even shock. ECG shows ST-segment elevation, and elevated cardiac troponin levels help confirm the diagnosis. 5. **Sudden cardiac death**: The most severe manifestation of CAD, characterized by abrupt loss of consciousness and death.

Diabetes mellitus is a major contributing factor to CAD; diabetic patients have a significantly higher risk of developing CAD compared with the general population. Similarly, obesity increases CAD risk. Therefore, individuals should engage in regular physical activity and maintain a healthy weight through safe, sustainable lifestyle modifications. Additionally, patients should abstain from smoking and alcohol consumption—both well-established risk factors for CAD.

Patients are advised to avoid smoking and alcohol entirely and to consume a nutritionally balanced diet—avoiding overeating or binge eating. We hope this information proves helpful.
