Risk of stroke in people with high blood pressure


People who have both high blood pressure and a high heart rate of more than 100 times per minute, the higher the risk of heart attack, stroke, and heart failure.

Professor, Doctor, Doctor Truong Quang Binh, Director of the Cardiovascular Center, Deputy Director of Ho Chi Minh City University of Medicine and Pharmacy Hospital, said that heart rate, also known as heart rate, is the number of times the heart beats and contracts. per minute. The heart rate of a healthy person is about 60-100 beats per minute.

If the heart beats more than 100 times per minute, it is called tachycardia and less than 60 times per minute is called bradycardia. When the heart beats too fast, the heart has to work hard for a long time, leading to the heart not working as well as before and leading to heart failure.

If the heart beats too slowly with an index less than 30-40 times per minute, it will lead to anemia in the organs. When there is lack of blood to the brain, the patient will feel dizzy, possibly fainting.

People with a high heart rate have a higher risk of dying from cardiovascular events than people with a normal heart rate. Therefore, if the patient has both hypertension and high heart rate, the rate of cardiovascular events and death is many times higher. Patients with hypertension should maintain blood pressure below 130/80 mmHg, heart rate at about 60-70 beats/minute, Professor Truong Quang Binh said.

Not being fully aware of the influence of heart rate, voluntarily stopping the drug, increasing or decreasing the dose of the drug makes hypertensive patients prone to dangerous events.

Recently, the University of Medicine and Pharmacy Hospital in Ho Chi Minh City has also received emergency hypertensive patients with severe shortness of breath, chest pain, and heart palpitations up to 105 times per minute. Exploiting the history showed that the patients were diagnosed with high blood pressure, but when their health gradually stabilized, they took the medicine irregularly, sometimes quitting for two to three days in a row. After performing an electrocardiogram, the doctors assessed that stopping the drug caused the patient’s heart rate to rise excessively. If this condition persists, it can lead to heart failure and myocardial infarction.

According to Professor Truong Quang Binh, heart rate is affected by many factors. In which high blood pressure, anxiety, stress, lack of exercise, poor physical strength, anemia, pale body, pregnant people, thyroid disease – hyperthyroidism… can all cause increased frequency. heart number.

For hypertensive patients with high heart rate, the physician needs to consider all of the above factors and control immediately. If, after controlling these factors, the heart rate is still fast, the doctor will consider using appropriate drugs to reduce the heart rate and blood pressure for the patient to the desired target level.

However, the drug only works for one to two days. Abrupt discontinuation or voluntary reduction in dosage may cause the heart rate to rise again, and may even experience a rebound effect that increases the heart rate much higher. Therefore, when hypertensive patients are indicated to use heart rate-lowering drugs or heart rate-stabilizing drugs, the discontinuation or reduction of dose must be gradual and decided by a cardiologist. circuit.

“Patients should not arbitrarily stop or reduce the dose of the drug suddenly. This can increase blood pressure and increase heart rate at the same time, causing many dangerous complications,” emphasized Dr. Binh.

Master, Doctor Nguyen Dinh Son Ngoc – Department of Cardiology, Ho Chi Minh City University of Medicine and Pharmacy Hospital recommends that during the current epidemic, people with cardiovascular diseases in general and hypertension in particular is one of the subjects at risk of severe disease if infected with nCoV.

According to Dr. Ngoc, a study on people with Covid-19 showed that the death rate in people with cardiovascular disease was 5 times higher than in the general population. Therefore, in addition to complying with the principles of disease prevention of the Ministry of Health, patients need to immediately check the number of drugs they currently have. If there is less, you need to call the treating doctor or the specialized clinic where you are being monitored to promptly supplement and take the full medication as prescribed. It is necessary to check and make sure that there are basic medical equipment such as thermometers, blood pressure monitors, etc. In case of re-examination, must wear a mask and strictly follow regulations and instructions. of medical facilities.

If there are symptoms of shortness of breath, heaviness in the chest, increasing fatigue or unstable blood pressure and heart rate, the patient should notify the doctor to receive appropriate management instructions. If you have severe symptoms such as shortness of breath, severe chest pain, cyanosis, confusion, etc., you should immediately call the emergency unit to be transferred to the nearest hospital.

In terms of lifestyle, patients need to maintain a healthy lifestyle and live in moderation. Should exercise moderately, ensure to limit contact according to epidemic prevention regulations and have a scientific and nutritious diet. In addition, patients should get enough sleep, do not stress too much and do not abuse alcohol and stimulants.
