高血压若长期发展,不予治疗控制,一般总是在10～20年后影响人体的主要脏器使其产生病变。其中最易受到影响的是心、脑、肾以及眼等器官,同时产生多种并发症。一、高血压容易发展成为高血压性心脏病长期的血压升高,带给心脏的负担是沉重的,特别是心脏的左心室,为了克服血管的阻力,左心室必须用更大的收缩力将血液喷射出去,如此每日代偿性增加心脏的收缩力,于是,左心室的肌肉逐渐肥大起来。高血压发展到中、后期,除心肌变得肥厚外,出现心室扩大,主动脉弓弹开扩张,心脏的代偿功能开始减退,心肌的收缩能力也不断降低,最终发展成高血压性心脏病。病人可以有心悸、气短、眼花、心前区不适、咳嗽等症状。
If the long-term development of hypertension, no treatment control, usually 10 to 20 years after the main organ affecting the body to make lesions. One of the most affected is the heart, brain, kidney and eye and other organs, while producing a variety of complications. First, high blood pressure easily develop into hypertensive heart disease Long-term blood pressure, heart to heart burden is heavy, especially the left ventricle of the heart, in order to overcome vascular resistance, the left ventricle must be greater contraction force Blood jet out, so compensatory daily increase in cardiac contractility, so the left ventricular muscle gradually hypertrophy. Hypertension to the development of the late, in addition to myocardial hypertrophy, ventricular enlargement occurs, the aortic arch pop open expansion of the heart compensatory function began to decline, myocardial contractility also continue to decline, eventually developing into hypertensive heart disease. Patients may have heart palpitations, shortness of breath, vertigo, precordial discomfort, cough and other symptoms.
