Classification of Coronary Heart Disease

Today, frequent late-night work and study have exerted significant negative impacts on people’s health—reducing immune function and disrupting endocrine balance. Excessive workloads place undue stress on the heart, with coronary artery disease (CAD) being one of the most common resulting conditions. So, how is CAD classified?

Classification of Coronary Artery Disease

CAD is classified into five main types: silent myocardial ischemia, angina pectoris, myocardial infarction, ischemic cardiomyopathy, and sudden cardiac death. Myocardial infarction and sudden cardiac death carry high mortality rates and pose serious threats to patients’ lives. Heart failure and arrhythmias are common complications of CAD. Acute extensive anterior wall myocardial infarction is particularly prone to concurrent heart failure and malignant arrhythmias; therefore, prompt treatment—including rapid revascularization, restoration of blood flow and oxygen supply to myocardial cells, reduction of infarct size, salvage of jeopardized myocardium, preservation of cardiac function, and prevention or mitigation of arrhythmias—is essential.

CAD predominantly affects middle-aged and elderly individuals. Many patients remain asymptomatic at onset and experience no interference with daily activities or work. Occasionally, they may notice mild discomfort in the precordial region or general fatigue. Although early-stage disease may not significantly impair quality of life, timely diagnosis and intervention are crucial to prevent progression to advanced, difficult-to-treat stages.

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