People with high blood pressure have these 3 abnormalities in their fingers, and cerebral infarction may be approaching quietly

Mr. Cao, 66, lives alone and has a long history of hypertension and diabetes. He usually takes medication regularly and his condition is under control. A week ago, Mr. Cao suddenly felt that his right hand was not flexible, he could not hold chopsticks steadily, and his fingers were numb . At first, he did not pay much attention to it, thinking it was just because of his old age. However, two days later, his left hand also began to become weak, he could not hold things steadily, and it was difficult to lift his hand . Accompanied by his children, he went to the hospital for treatment.

The doctor performed a brain MRI on Mr. Cao, and the result showed cerebral infarction . Unfortunately, when Mr. Cao came to the hospital, it had been more than 24 hours since the onset of the disease, and he missed the best time for thrombolysis (within 6 hours of onset) , so he could only receive conservative medical treatment. Fortunately, his infarction area was small, and after hospitalization, infusion, rehabilitation training, and acupuncture and physiotherapy, his condition gradually stabilized.

Doctors remind: Hypertension is an important risk factor for cerebral infarction. Studies have shown that 93% of patients with cerebral hemorrhage and 86% of patients with cerebral infarction have a history of hypertension. Hypertension can cause damage to blood vessel walls, increase the risk of blood vessel blockage, and thus cause cerebral infarction. Therefore, patients with hypertension need to be especially vigilant about the occurrence of cerebral infarction.

So, how can we identify the early symptoms of cerebral infarction? In fact, our fingers are a good "alarm".

Three abnormal signals of fingers

1. Numbness in fingers

Hypertensive patients should be highly alert if they suddenly experience numbness in their fingers, especially numbness in one hand or one limb . This numbness is different from ordinary finger numbness, and it will not be relieved by rubbing or resting . This is because when blood vessels in the body are blocked, the fingers, as nerve endings, will first feel the abnormality.

2. Inflexible and stiff fingers

Since the brain controls the body's movements and sensations, when the brain's blood circulation is blocked and it is deprived of blood or oxygen, it will affect the normal function of nerves and muscles. Fingers may become stiff and limited in movement, such as being unable to hold things steadily and writing becoming inflexible . If hypertensive patients find that their fingers have these symptoms and they persist, they should seek medical attention in time to avoid missing the best time for treatment.

3. Weak hands or trembling

Before a stroke, patients may experience transient hand weakness, medically known as muscle weakness. Patients may feel weak in their hands and feet, and have difficulty lifting heavy objects or walking in mild cases. In severe cases, they may even be unable to lift their hands and feet, and one side of the limbs may be completely paralyzed.

Some patients may experience finger tremors before a cerebral infarction. This is because nerve conduction is disturbed, causing the muscles to be unable to stably control the movement of the fingers.

How to prevent cerebral infarction if you have high blood pressure?

1. Reasonable control of blood pressure

Keep systolic blood pressure stable within 140mmHg and diastolic blood pressure stable between 70-90mmHg. Take medications at regular times and dosages strictly according to doctor's orders, monitor blood pressure levels regularly, and take medications on time even if blood pressure is normal, and avoid increasing or decreasing the dosage of medications at will.

2. Pay attention to temperature changes

Middle-aged and elderly patients with hypertension are weak and prone to illness. Pay special attention to the temperature changes between summer and winter, and avoid large temperature differences between indoors and outdoors. In winter, the temperature is low between 6 and 8 in the morning, so try to avoid going out during this time. If you have to go out, be sure to keep warm.

3. Maintain a good mood

Anger, fear, anxiety, etc. can cause high blood pressure. Long-term emotional depression, excessive tension, mental work, adverse mental stimulation, etc. can cause dysfunction of the cerebral cortex and increase peripheral vascular resistance.
