| 설명 | 심장동맥이란 심장에 혈액을 공급하는 동맥을 말한다. 심장도 다른 근육과 마찬가지로 혈액을 공급받아야 수축을 할 수가 있는 기관으로 심장의 혈액을 공급하는 동맥을 심장동맥이라고 한다. 심장동맥병이란 심장동맥의 내경이 좁아져서 생기는 질환으로 허혈심장병(ischemic heart disease)이라고도 불린다. 관상동맥이 좁아질 경우에는 심장으로 가는 혈액의 양이 적어져서 심장에 충분한 혈액이 공급이 되지 못하므로 여러 가지 병적인 현상이 생긴다. 심장동맥이 좁아지는 데에는 여러 가지 원인이 있을 수가 있으나 주로 심장동맥의 동맥경화증에 의한다. 동맥경화증이란 동맥의 내층에 지방과 콜레스테롤로 이루어진 죽종(atheroma)가 생기는 질환으로 죽종이 생긴 동맥은 죽종이 혈관의 내부로 돌출하게 되어서 혈관의 내경이 작아지게 된다. 심장동맥병은 그 정도에 따라서 협심증(angina pectoris)와 심근경색증(myocardial infarction)으로 나눈다. 협심증은 심장동맥의 부분적 폐쇄에 의해서 평상시에는 증상이 없지만 심장이 많은 활동을 할 경우에 심장에 피가 충분한 만큼 공급이 되지 않아서 생기는 질병으로 평상시에 쉴 경우에는 아무 증상이 없지만 운동이나 과식 등의 원인으로 심장이 많은 운동을 할 경우에 심장에 공급되는 혈액의 양이 모자라서 증상(대개 가슴부위에 쥐어짜는 듯한 통증)이 생긴다. 심근경색증이란 심장동맥의 완전폐쇄에 의해서 심장의 근육이 혈액을 전혀 공급받지 못해서 심장의 근육이 썩는 경우를 말한다. |
