In 1945, President Roosevelt died of a cerebral hemorrhage when his blood pressure was as high as 300/190 mmHg. Was the cerebral hemorrhage that occurred to President Roosevelt caused by high blood pressure? The answer is yes, high blood pressure can bring many cardiovascular and cerebrovascular diseases, is one of the important killers that threaten human life, let’s learn together the hazards brought about by high blood pressure. Why is hypertension so terrible? Because sustained elevated blood pressure can cause heart, brain, kidney, and systemic vascular damage, and in severe cases, life-threatening clinical complications such as stroke, myocardial infarction, heart failure, renal failure, and aortic coarctation. For example, hypertension can cause stroke (cerebral infarction, cerebral hemorrhage), transient ischemic attack, etc. Stroke is an important cause of vascular dementia. China is a high incidence of stroke, with 2.5 million new strokes per year month, 70% of which are related to hypertension. Although hypertension is very dangerous, if we take appropriate measures to actively control blood pressure, this can reduce the harm it brings. Good blood pressure control can reduce the risk of myocardial infarction by 5-30%, the risk of heart failure by 50%, and the risk of stroke by 40-50%. So how do we treat blood pressure? The key points to remember about lowering blood pressure: Lower blood pressure early, benefit early Long-term lowering of blood pressure, benefit long-term Lowering of blood pressure to achieve the standard, maximum benefit Adherence to treatment and blood pressure to achieve the standard can minimize and delay the occurrence of complications, improve quality of life and extend life expectancy. To reap the benefits of lowering blood pressure, most patients must adhere to long-term standardized antihypertensive medication.
