Hypertension has become the world's most common cardiovascular disease, but also China's cardiovascular and cerebrovascular diseases in the most kind. On the great human health threat, but will also cause the decline in the quality of life. According to the Health department statistics show that China's hypertension patients have more than 130 million people, the prevalence rate of around 13%, and an annual increase rate Sphygmomanometer of 3 million, of which the prevalence rate of hypertension in the elderly is as high as 25% -35%.
So, what is hypertension? In introducing the definition of hypertension before, need to understand what is blood pressure? Blood pressure refers to the so-called vascular blood flow in the vessel walls from lateral pressure. Is an increase in arterial pressure for the characteristics of the disease, with the device in the brachial artery was measured values to express to mmHg (mm Hg) or kPa (kPa) for the unit, which is blood pressure. Records usually two to record blood pressure at the data, the higher a period of contraction in the heart, that is, systolic blood pressure. The one with a lower heart rate between the two appeared in the heart of diastolic, or diastolic blood pressure.
The relationship between lifestyle and hypertension
Obesity and Hypertension
1984 Erwteman definition for obesity, such as body mass index of more than 30 kg/m2, after 1990 and put forward Cassano 2 / 3 of patients with hypertension induced by obesity. In particular, the waist / hip ratio to measure abdominal obesity a target, regardless of how body weight, and after this indicator is closely related to hypertension. Moreover, in patients with obesity and hypertension-prone risk factors for cardiovascular events in a series of mechanisms, and these mechanisms include the excitement of the sympathetic nervous system, fat metabolism disorder, sodium transit obstacles, as well as insulin resistance. Therefore, obesity not only Sphygmomanometer high blood pressure, but also a significant increase in addition to the impact of hypertension risk of cardiovascular events. 1998, it is estimated that obesity in England alone, the Government has increased its 4.57 billion pounds of additional medical burden, mainly obesity on hypertension and cardiovascular diseases caused by the impact. Health nurses abroad a 18-year follow-up studies and expert follow-up of 10 health of the findings were that: weight gain will enable the occurrence of hypertension risk has been greatly increased.
Alcohol consumption and hypertension
A substantial amount of research data shows that excessive drinking is associated with hypertension. Most of the data show that the number of alcohol and blood pressure levels of positive linear correlation. In addition, alcohol can increase the incidence of hypertension in the crowd and dangerous. Canada to a recent study, more than 4% of the 60-64 year-old male patients with hypertension, excessive drinking is the main reason for their suffering from hypertension. Although the study did not prove that drinking and whether causal relationship between hypertension, but continued observation data accumulated, can be drawn from this is a causal link.
Exercise and Hypertension
Intense physical activity can cause short-term elevated systolic blood pressure, but relatively paradox is now strong evidence that the laws of physical activity on patients with mild hypertension great help to lower blood pressure can be 8 / 4 mmHg, for those who minimal basis with the volume of activities is the most important, but it increased exercise capacity and the relevance of low. In other words, the overwhelming majority of sedentary patients can be appropriately increased physical activity and gain the greatest benefits. Clinical experiments show that, in patients with severe hypertension, through 16 weeks of aerobic exercise, not only a significant reduction in blood pressure, left ventricular mass index was significantly lower. In addition, several studies show that the impact of exercise on blood pressure does not depend on body mass index of any change in the indicators of increased activity may guide the entire way of life as Sphygmomanometer part of the adjustment method. To the laws of moderate physical exercise to the harm small. But for easy sick individual, in some cases, sudden movement can cause asthma, consumption induced by physical exercise can angina, and very few circumstances, lead to myocardial infarction. Movement on those after onset of symptoms (asthma, angina pectoris) of the individual, the need to reduce or in the exercise under the guidance of doctors tight moderate exercise training. It is worth noting that, even if confirmed by atherosclerotic disease patients, whether or not they suffer from high blood pressure, they should promote the laws of physical activity to reduce the risk of cardiovascular events and death. Therefore, patients with hypertension, should not be a potential short-term risk of increased physical activity as a stumbling block, because physical activity brought about by the benefits far can make up for its harmful consequences.
Hypertension is divided into stages
According to the World Health Organization (WHO) and the International Union of hypertension (ISH), based on diastolic blood pressure level and the extent of organ involvement hypertension divided into mild, moderate, severe or 1, 2, 3 hypertension, acute hypertension, or high blood pressure risk such as 4
Hypertension What is the reason
Hypertension their cause so far, is not very clear. But now recognized: from the influence of various factors, the regulation of normal blood pressure and the formation of dysfunctional. Survey data indicate that large epidemic: cortical dysfunction, senior nerve center of dysfunction in the onset of the dominant, fluid, endocrine, kidney disease participation in the process.
External environment and internal stimulation can cause adverse strong and repeated, prolonged mental stress and emotional fluctuations, resulting in the cerebral cortex excitement and inhibition disorder, vasoconstriction of the central and sympathetic nervous excitement increased, induce systemic arterial systolic small, peripheral vascular resistance increased blood pressure also will be increased.
Small artery prolonged contraction of small blood vessels, Sphygmomanometer there may be obstacles to nutrition, and this lipid deposition, gradually undergoing a wide range of small arteriosclerosis. The visceral organs, can lead to ischemia, particularly renal ischemia, can produce renin, the renin-angiotensin liver to the formation of angiotensin, to a more systemic arterial small contraction, high blood pressure is more obvious. It has also stepped up its small systemic arteries hardening, so blood pressure from the temporary, to the increase of volatility lasting hypertension.
