The survey shows that the treatment rate of patients with hypertension in China is only 34.9%, and the control rate is only 11%. There are still many misunderstandings in the prevention and treatment of hypertension. For example, some people say that antihypertensive drugs cannot always take the same kind for a long time, otherwise they will develop drug resistance. Is this true? Jiang xiongjing, deputy director of the vascular center of Fuwai Hospital, Chinese Academy of Medical Sciences: This is a relatively wrong understanding. As long as the drug has no side effects, the blood pressure drops very smoothly for you. You can stick to it. On the contrary, if you change a new medicine that you have never tried before, it may be effective for you, or you (blood pressure) can't control it after changing the medicine. You think everything is new and good after changing the medicine. It's just that this antihypertensive medicine is not necessarily new and good. Antihypertensive drugs are the most suitable for you. The medicine with the best blood pressure is the best for you. Some people believe that high blood pressure doesn't matter. As long as there are no uncomfortable symptoms, they don't need to take medicine. In fact, there are generally no symptoms in the early stage of hypertension, but no symptoms do not mean no harm. The damage to various organs has begun at the moment when the blood pressure rises. Jiang xiongjing, deputy director of the vascular center of Fuwai Hospital, Chinese Academy of Medical Sciences: the biggest misunderstanding of hypertension is the misunderstanding of not paying attention to it. I don't feel anything. I don't have hypertension and never measure it. The second misunderstanding is whether to take medicine for high blood pressure. We see how blood pressure evolves. If the process of evolution is continuous hypertension and slowly rising, we must take medicine. Another misunderstanding is that, for example, I eat when my blood pressure is high today, I don't eat when my blood pressure is low tomorrow, and I eat when my blood pressure is high the day after tomorrow - this is a typical misunderstanding. We say you must stick to the medicine for lowering blood pressure. The earlier the blood pressure is controlled, the less damage to the heart, brain, kidney and other organs. People always hope to take effect immediately after taking antihypertensive drugs. However, reducing blood pressure requires a smooth and slow process. If blood pressure drops too fast, it will cause insufficient perfusion of heart, brain, kidney and other organs, resulting in ischemia. General patients should be treated for 4-12 weeks to make their blood pressure meet the standard. (outlook new era)
