The damage of high blood pressure (hypertension) to internal organs occurs in a long process and high blood pressure can induce a series of complications (Such as left ventricular hypertrophy, coronary heart disease, miocardial infarction, stroke, renal inadequacy, uremia and so on).
Harm to the Heart
High blood pressure (hypertension) often changes the structure and function of the heart. The long-term elevation in blood pressure increases the burden on the left ventricle and involves it for a long time. Therefore, the left ventricle gradually thickens and dilates, thereby resulting in hypertensive heart disease. High blood pressure can accelerate the development and progression of atherosclerosis and increase the oxygen consumption of myocardium, thus causing angina, myocardial infarction, heart failure, sudden death, etc. People often call high blood pressure and coronary heart disease twin sisters.
Harm to the Brain
Clinically, cerebrovascular diseases caused by high blood pressure mainly include cerebral hemorrhage (hemorrhagic stroke), hypertensive encephalopathy, cerebral infarction (ischemic stroke), while cerebral hemorrhage is the most common severe complication of high blood pressure.
Harm to the Kidney
The damage of of high blood pressure to the kidney starts mainly from the small arteries. At first, renal arteriolar sclerosis and stenosis lead to renal ischemia. Some nephrons experience fibrosis and hyaline change of arterioles, while some other normal nephrons manifest compensatory hypertrophy. With the continuous progression of the disease, the surface of the kidney becomes granular and its cortex gets thinner. Because of the constant damage of nephrons, the kidney begins to be atrophic and subsequently suffers from renal insufficiency. Once the disease progresses into uremia, the damage to the kidney will be irreversible.
Harm to the Fundus Oculi
When of high blood pressure progresses to a certain level, the retina may manifest bleeding, edema, exudes, with papilloedema occurring in severe cases. With the progression of the disease course, some substances that exude deposit on the retina and radial yellow points occur at the fundus oculi, which will cause visual disorders in patients at this time.
Harm to the Artery: Form Aneurysm
The harm of high blood pressure are the damage to the artery walls by elevated blood pressure, which can cause main artery walls to weaken, inelasticity, this is easy to generate an aneurysm in a main artery, it could be life-threatening. This is equivalent to installing a time bomb in the body.
