According to the national survey on nutrition and health status of 270,000 residents organized by the Ministry of Health in 2002, the prevalence of hypertension among people aged 60 and above in China was 49%. In other words, about one in every two people over 60 years old suffers from hypertension. Hypertension in the elderly often coexists with a variety of diseases and complications, often complicated by coronary heart disease, heart failure, cerebrovascular disease, renal insufficiency, diabetes, etc. On the contrary, the awareness rate, treatment rate and control rate of hypertension are very low, only 30.2%, 24.7% and 6.7% respectively, and hypertension has become a serious threat to the health of the elderly as a major chronic disease and a focus of community prevention and control. However, hypertension is preventable and controllable, and a summary analysis of elderly hypertension trials shows that antihypertensive treatment can reduce stroke by 40% and cardiovascular events by 30%; whether systolic or diastolic hypertension or ISH, antihypertensive treatment can reduce the incidence of cardiovascular and cerebrovascular disease and mortality; an average reduction of 10 mmHg systolic and 4 mmHg diastolic blood pressure reduces the risk of stroke by 30% and cardiovascular events and mortality by 13%. In addition, cardiovascular events and mortality were reduced by 13%, with more benefit in older men over 70 years of age, those with increased pulse pressure or cardiovascular comorbidities. As long as the following three points are mastered, the ideal blood pressure reduction is not difficult. 1, comprehensive lifestyle intervention is the basis. Hypertension is a modern lifestyle disease, and overweight or obesity, high-salt diet, and alcohol consumption are the main modifiable risk factors. Intervention content, including five times a week of moderate intensity exercise, 30 minutes each time, 6,000 steps a day on their own, maintain a healthy weight or weight loss of 5% – 10%; a light diet, limited to 6 grams of salt per person per day; do not drink alcohol or moderate drinking, if drinking alcohol men do not exceed 2 standard cups, women do not exceed 1 standard cup (1 standard cup is equivalent to 12 grams of alcohol, which is about 360 grams of beer, or 100 grams of wine, or 30 grams of liquor), etc. Lifestyle interventions for hypertensive patients must be adhered to for life. 2, the elderly hypertension lowering blood pressure has a target value, there is a process to achieve the standard. When diastolic blood pressure (DBP) <60mmHg, such as systolic blood pressure (SBP) <150mmHg, it is observed and can be done without drugs. Starting treatment blood pressure ≥150/90mmHg. Target value of blood pressure reduction: ① Patients ≥65 years old, blood pressure down to <150/90mmHg, if tolerated can be further reduced to 140/90mmHg or less; ② Patients ≥80 years old in advanced age, general blood pressure should not be <130/60mmHg; ③ Elderly hypertension combined with diabetes, coronary heart disease, heart failure and renal insufficiency patients with hypertension Target value <140/90mmHg. Achievement process: ①Patients starting available monotherapy: blood pressure <160/100mmHg or systolic blood pressure 150--170mmHg/diastolic blood pressure <60mmHg or risk stratification as intermediate risk; ②Patients starting combination medication: blood pressure ≥160/ 100mmHg or systolic blood pressure >180mmHg/diastolic blood pressure <60mmHg or risk stratification as high risk. This requires professional guidance, and patient friends should not take the initiative. 3, 24h steady pressure lowering is the most important, elderly hypertensive patients should choose safe, less side effects, easy to take, high compliance with the drug. Older patients have more blood pressure "morning peak" phenomenon, hypertension combined with postural hypotension and postprandial hypotension increased, common blood pressure circadian rhythm abnormalities. When blood pressure fluctuates sharply, it affects the therapeutic effect and can significantly increase the risk of cardiovascular events. The elderly have poor memory and are prone to missed or repeated doses. Therefore, it is best to choose drugs that can be taken once a day and can lower blood pressure smoothly for 24H, such as long-acting calcium channel blockers, long-acting ACEI or ARB.
