Heart damage the damage of hypertension to the heart is mainly manifested in the following two aspects: first, the damage to the heart and blood vessels. Hypertension mainly damages the coronary artery of the heart, and gradually causes coronary artery atherosclerosis and coronary heart disease. The left ventricular load is increased, the myocardial strength is increased, and the myocardial oxygen consumption is increased.
When combined with coronary atherosclerosis, the coronary artery blood flow reserve function is reduced, and the myocardial oxygen supply is reduced. Therefore, angina pectoris and myocardial infarction appear. The second is the damage to the heart itself. The arterial pressure increases continuously, increasing the burden of the heart and forming compensatory left ventricular hypertrophy. Prone to ventricular hypertrophy, further leading to cardiac expansion. The heart damage caused by hypertension can lead to arrhythmia, heart failure and sudden cardiac death.
Cerebral vascular damage dizziness and headache are the most common brain symptoms of hypertension. Most of the patients show persistent depression and discomfort. Frequent dizziness can hinder thinking, reduce work efficiency, distract attention, and reduce memory, especially recent memory loss. Clinically, acute cerebrovascular diseases caused by hypertension mainly include cerebral hemorrhage and cerebral infarction.
The lesion location, amount of hemorrhage and emergency treatment of cerebral hemorrhage have a great relationship with the prognosis of patients. Generally, the mortality rate is high. Even survivors still have sequelae such as hemiplegia or aphasia, and the patients are disabled.
Renal damage hypertension has a close and complex relationship with renal failure. On the one hand, hypertension causes renal damage; On the other hand, renal damage worsens the prognosis of hypertension. In general, the damage of hypertension to the kidney is a long process. Due to the strong compensatory capacity of the kidney, the only symptom that can reflect the disorder of renal self-regulation at the beginning is increased nocturia.
Long term hypertension can lead to renal arteriosclerosis. When the renal insufficiency develops further, the urine volume decreases obviously, the non protein nitrogen, creatinine and urea nitrogen in blood increase, the whole body edema, electrolyte disorder and acid-base balance disorder appear. Once the kidney appears dysfunction or develops into uremia, the damage is irreversible.
Hypertension can be divided into primary and secondary
The hypertension we often talk about is not caused by other diseases, but is itself a disease, called primary hypertension, also known as hypertension, or simply hypertension. The majority of hypertension is essential hypertension. Essential hypertension is a polygenic genetic disease, which is caused by the interaction of genetic genes and environmental factors.
Polygenic genetic disease is a genetic disease caused by the interaction of multiple genes and environmental factors. Its genetic mode is complex, and it is difficult to determine which is normal and which is sick in a family. Only by studying a large number of patients can we determine the role of genetic factors in the occurrence of polygenic diseases. Polygenic diseases have a family aggregation phenomenon. In addition to genetic factors, similar living habits and environmental factors of a family also have a greater impact.
The study found that the probability of children suffering from hypertension in the future was as high as 45%; One parent is hypertensive, and the probability of children suffering from hypertension is 28%; However, the probability of children with normal blood pressure was only 3%. Although the living environment of the biological children and the adopted children of the patients with hypertension is the same, the biological children are more likely to suffer from hypertension.
Moreover, the risk of hypertension in patients with family history of hypertension was 1.79 times higher than that in patients without family history of hypertension, and the prevalence of hypertension in patients with both parents with family history of hypertension was 2 times higher than that in patients without family history of hypertension. In addition to genetic factors, life habits also have a great impact on hypertension. If the family history of hypertension is healthy and regular, the probability of hypertension will be greatly reduced; People without a family history of hypertension have an unhealthy and irregular life and are also prone to hypertension.
In addition, some diseases can cause hypertension, for example, hypertension caused by chronic nephritis and other kidney diseases is called renal parenchymal hypertension, hypertension caused by renal artery stenosis is called renal vascular hypertension, and the two are also called renal hypertension; Primary aldosteronism can also cause hypertension. These hypertension caused by other diseases are collectively referred to as secondary hypertension. Hypertension is a symptom of these diseases, but secondary hypertension is relatively rare.
What's more,you should wear a BP smart watch to monitor your blood pressure everywhere and anytime.Therefore you may better avoid the damage.
