Introduction

CHD is the abbreviation for coronary heart disease, which has a relatively high incidence among cardiovascular diseases and poses a serious threat to physical health, requiring active treatment. Coronary heart disease is a type of ischemic heart disease primarily caused by atherosclerotic lesions in the coronary arteries, leading to narrowing or blockage of the blood vessels. This impairs adequate blood and oxygen supply to the myocardium, resulting in myocardial necrosis and subsequent heart disease.

CHD is the abbreviation for coronary heart disease. Among cardiovascular diseases, coronary heart disease has a relatively high incidence rate and poses a serious threat to physical health, thus requiring active treatment.

Coronary heart disease is a type of ischemic heart disease primarily caused by atherosclerotic lesions in the coronary arteries. These lesions lead to narrowing or blockage of the blood vessels, preventing sufficient blood and oxygen supply to the myocardium, which may result in tissue necrosis and cause heart disease. Common symptoms include chest tightness, chest pain, and back pain; some individuals may also experience epigastric (stomach area) pain. Diagnosis requires medical evaluation through coronary CT angiography or coronary angiography. Once confirmed, medications such as clopidogrel tablets or aspirin tablets can be used under medical supervision. These drugs help prevent platelet aggregation, inhibit thrombosis, improve coronary blood flow, and alleviate symptoms of myocardial ischemia.

In addition, coronary heart disease may result from unhealthy dietary habits leading to lipid plaque deposition in the coronary lumen, causing vascular narrowing and myocardial ischemia. Appropriate drug therapy should be selected based on the specific underlying causes.

Nursing Issues and Interventions for Coronary Heart Disease

This condition can be diagnosed through blood tests, electrocardiography (ECG), and echocardiography. Antiplatelet medications should be used under a physician’s guidance to improve outcomes. Coronary artery disease is primarily caused by narrowing of the coronary arteries; smoking regularly further increases the risk of developing this disease. Early symptoms are often subtle. ECG examination helps identify abnormalities.

How to Diagnose Coronary Heart Disease

Currently, imaging examinations remain the most important diagnostic method for coronary heart disease. Among these, coronary angiography is considered the gold standard for diagnosing coronary heart disease—that is, the most accurate method available. If coronary angiography cannot be performed due to personal or objective constraints, alternative tests such as coronary CT angiography (CTA) may be used.

Can coronary heart disease be fatal?

Patients with coronary artery disease (CAD) may die, particularly those with myocardial infarction (MI). Due to myocardial cell necrosis, electrocardiographic instability commonly occurs. Clinically, this manifests as various arrhythmias—including malignant arrhythmias, ventricular tachycardia, or ventricular fibrillation—resulting in a high mortality rate. Anterior wall MI is especially likely to impair the heart’s pumping function, leading to heart failure and further increasing the difficulty of resuscitating patients with CAD.

Clinical Types of Coronary Heart Disease

The five clinical types of coronary heart disease are as follows: 1. Silent myocardial ischemia—patients typically have no symptoms; most cases are detected incidentally during routine physical examinations or electrocardiography (ECG). 2. Ischemic cardiomyopathy—caused by long-standing coronary artery disease and chronic myocardial hypoperfusion, leading to reduced cardiac contractility and cardiac enlargement. Color Doppler echocardiography aids in diagnosis.

Can coronary heart disease be cured?

Currently, coronary artery disease (CAD) cannot be cured clinically because the onset and progression of atherosclerosis are irreversible. Available treatment options include pharmacotherapy and interventional procedures, aimed at slowing the progression of atherosclerosis; however, current therapies cannot reverse the pathological process of atherosclerosis. Therefore, CAD remains incurable at present.

Classification of Coronary Heart Disease

Classification of coronary artery disease (CAD) includes asymptomatic myocardial ischemia, angina pectoris, myocardial infarction, ischemic cardiomyopathy, and sudden cardiac death. Myocardial infarction and sudden cardiac death carry high mortality rates and pose a severe threat to patients’ lives. Heart failure and arrhythmias are complications of CAD. Acute extensive anterior wall myocardial infarction is most commonly associated with heart failure and malignant arrhythmias.

Is coronary heart disease the same as heart disease?

Coronary heart disease (CHD) is a type of heart disease. Heart disease encompasses CHD; thus, a diagnosis of CHD also implies a diagnosis of heart disease. To diagnose CHD, coronary angiography is typically required, supplemented by other diagnostic tests such as electrocardiography (ECG), color Doppler echocardiography, and X-ray imaging. A comprehensive assessment of the patient’s condition is essential to guide appropriate therapeutic interventions.

Is coronary heart disease hereditary?

Coronary heart disease (CHD) is not a hereditary disease; however, it does exhibit a certain degree of genetic predisposition. Patients may carry genetic risk factors, such as a family history of premature atherosclerosis. Premature atherosclerosis refers to the occurrence of CHD or stroke in one’s parents before age 40. This exerts adverse effects on offspring and increases their risk of developing CHD.
