Some hypertensive patients always have recurring blood pressure during the course of taking medication, which is related to the existence of some misconceptions about taking medication in many patients, the most common of which are 5 major mistakes that need to be corrected and clarified. We often say that “hypertension is a silent killer”, that is, the danger of hypertension is not in the hypertension itself, nor does it lie in the presence of symptoms, but in the fact that blood pressure can continue to rise to cause damage to the heart, brain, kidneys and other important organs, once the complication of stroke, heart failure, uremia. I’m afraid the consequences are unthinkable. The principle of individualization is one of the principles of the treatment of hypertension, because each patient’s condition is different, coupled with a wide range of anti-hypertensive drugs, each patient how to use drugs are different. For example, one patient may do well with the angiotensin-converting enzyme inhibitor “Mono”, but another patient may have to stop taking it because of a dry cough that is not tolerated. Some patients with diuretics alone or in combination with diuretics have a very good effect on lowering blood pressure, but gout patients may be aggravated by the disease. This is also a common misconception. The current anti-hypertensive drugs are a guideline to treat the symptoms but not the root cause, that is, they can only control blood pressure but not completely cure it, so anti-hypertensive treatment should be indefinite. It is well documented that if hypertensive patients stop taking medication, their blood pressure will return to the pre-treatment level sooner or later. Therefore, when your blood pressure drops to normal, it does not mean that you can stop taking anti-hypertensive medication. If you want to keep your blood pressure at a normal level and live a healthy life, you must insist on taking anti-hypertensive drugs. Fourth, the elderly blood pressure can not be reduced to normal, otherwise it will affect the blood perfusion of the organs This is not justified. As we know, under the condition that the blood volume and heart beat output remain unchanged, the change of blood pressure is mainly determined by the resistance of peripheral blood vessels. This increased resistance is mainly caused by the sclerosis of large arteries and the constriction of small resistance arteries. Therefore, hypertension is the combined result of both, and it does not increase the effective circulating blood volume of the organs. Therefore, a decrease in blood pressure to normal in the elderly does not affect the blood perfusion to the organs. Of course, elderly patients with hypertension should closely monitor their blood pressure during medication because of the increasing aging of blood vessels, thickening and hardening of the walls, narrowing of the lumen, and restriction of vasodilation and contraction functions, and observe that the drug treatment cycle should be slightly longer, generally adjusting the drug dose after 1 to 2 weeks of medication. Fifth, the new listing of antihypertensive drugs than the old antihypertensive drugs a desirable antihypertensive drugs should have the following five conditions: First, with effective antihypertensive effect, and does not produce drug resistance; Second, can inhibit and reverse hypertension caused by heart, brain, kidney and vascular damage; Third, can reduce or not increase other cardiovascular risk factors, such as hyperlipidemia, hyperglycemia, hyperuricemia, etc.; Fourth, does not aggravate the accompanying other diseases such as slow lung Fourth, it does not aggravate other diseases such as chronic obstructive pulmonary disease, diabetes, coronary heart disease, renal insufficiency, heart failure, etc. As long as the above five points are met, regardless of the old drugs and new drugs are good drugs. For each specific patient, the drug that can effectively control blood pressure and suitable for long-term treatment is a good antihypertensive drug.
