How is chest impediment from the Donguibogam understood in modern medicine? It corresponds closely to the condition known as angina pectoris. Angina pectoris occurs when the coronary arteries that supply blood to the heart become narrowed or blocked. The heart functions like an engine pumping blood throughout the body. If the pipeline delivering fuel to this engine narrows, the heart cannot receive enough blood.
When the heart works harder, such as during exercise or periods of stress, it demands significantly more blood and oxygen than usual. Narrowed coronary arteries cannot meet this increased demand, causing oxygen deficiency in the myocardium. This manifests as chest pain, known as an anginal attack. It often presents as a tight squeezing sensation, heaviness, or pressure, and the pain may radiate to the left shoulder, arm, neck, or jaw.
The primary cause of coronary artery narrowing is atherosclerosis. Poor dietary habits, lack of physical activity, smoking, and chronic stress cause fatty plaques such as cholesterol to accumulate on vascular walls, making the vessels stiff and narrow. The traditional concept of cold qi or dampness-phlegm obstructing the pathways aligns with modern vascular narrowing caused by cholesterol accumulation. Likewise, a deficiency in yang qi corresponds to cardiac hypofunction or reduced metabolic capacity.
Because angina pectoris can progress to a life-threatening myocardial infarction, these chest symptoms should never be overlooked. Individuals with risk factors such as hypertension, diabetes, hyperlipidemia, or a history of smoking need to pay close attention to any bodily changes. Early detection, lifestyle adjustments, and appropriate medical treatment are essential. Just as the Donguibogam observes the body as an interconnected whole, maintaining cardiovascular health requires comprehensive attention to blood pressure, blood glucose, cholesterol levels, stress management, and mental well-being.
