Hypertension is quite common, but because there are no obvious symptoms, patients often only learn of its seriousness when complications such as stroke and cardiovascular disease occur. Local surveys show that nearly 30% of people aged 15 to 84 suffer from hypertension, and the prevalence among those aged 65 to 84 is as high as 57.4%. According to the guidelines of the World Health Organization (WHO) and the Hong Kong Department of Health, the standard value of high blood pressure is 140/90mmHg. However, according to the latest guidelines of the American Heart Association in 2017, normal blood pressure must be lower than 120/80mmHg. The standard is even stricter. Can further reduce the incidence of cardiovascular disease.
The relationship between heart rate and high blood pressure. In addition to blood pressure, heart rate is also a physiological index worth paying attention to. The normal adult resting heart rate is regarding 60 to 100 beats per minute. If it exceeds this range, it may indicate an irregular heartbeat and requires further examination. Although there is evidence from research that there is a certain relationship between blood pressure and heart rate. For example, people with a fast heart rate are more likely to develop high blood pressure, but in fact this relationship is not inevitable. However, in the treatment of high blood pressure, heart rate is an important indicator. Because some blood pressure-lowering drugs will also reduce the heart rate, doctors will prescribe appropriate blood pressure-lowering drugs according to the patient’s different physical conditions. It is recommended that when measuring blood pressure, you should also measure your heartbeat and accurately record these values for the doctor’s reference.

Controlling diet and taking medication to treat high blood pressure
If you are an early-stage obese hypertensive patient, diet and regular exercise can help lower your blood pressure, but you must persevere. More serious patients, such as those who have developed complications such as myocardial hypertrophy, or whose kidneys are damaged and have proteinuria, should take antihypertensive drugs as soon as possible. In addition, people with diabetes, hyperlipidemia, sleep apnea, and family history of stroke or heart disease are at greater risk of developing complications, so they should take medication early to avoid worsening of the condition.

Surgical treatment of stubborn hypertension
For some patients who cannot effectively control their blood pressure following taking multiple drugs, or who cannot tolerate the side effects of the drugs, renal artery sympathetic denervation may be considered. The sympathetic nervous system is distributed in many locations in the human body, with the most concentrated concentration on the walls of the renal blood vessels. When the system is stimulated, it puts the body into combat mode, secretes more adrenaline, constricts blood vessels, and increases blood pressure.
The principle of surgery is to reduce the activity of the sympathetic nervous system. The doctor will insert a catheter containing a metal point into the patient’s inguinofemoral artery. When it reaches the renal blood vessel, the metal point will stick to the blood vessel wall and emit radiofrequency energy to ablate the sympathetic nerves. Most patients’ blood pressure will drop significantly two to three months following surgery, and will gradually stabilize following six months to one year, and the dosage of medication can be reduced. However, this surgery may cause damage to the renal blood vessels. Therefore, six months to one year following the operation, the patient needs to undergo ultrasound or magnetic resonance scanning to follow up the condition of the renal blood vessels.
