Stroke over 70 years old, atrial fibrillation problems in over 30 percent

Cerebrovascular diseases are usually divided into strokes in which blood vessels in the brain are blocked and cerebral hemorrhage, which causes blood in the brain due to bursting blood vessels in the brain. As the demographic structure ages and the high blood pressure control rate increases, brain bleeding decreases and strokes increase in a situation where there was a lot of brain bleeding.
Stroke has many causes. It is classified into aortic infarction in which the beginning of carotid artery or cerebrovascular is blocked by atherosclerosis, a small blood vessel infarction in which small blood vessels are blocked, infarction caused by various causes, and embolic infarction in which blood clots derived from the heart, aorta proximal or carotid artery move along the bloodstream and block cerebrovascular vessels, and treatment varies depending on the cause.
Among the various causes, embolic infarction causes blood clots to form in places other than the cerebrovascular, and as this blood clots fall off, they flow into the cerebrovascular system, causing stroke as the cerebrovascular system is blocked. The most common cause is arrhythmia called atrial fibrillation. There are dozens of things in this arrhythmia, so doctors need to examine and test to diagnose atrial fibrillation.
Atrial fibrillation means that the left atrium, which needs to squeeze blood well and deliver blood to the left ventricle, is trembling without being able to squeeze blood properly. Atrial fibrillation causes about three direct problems.
First, palpitations occur when the atrium cannot properly squeeze blood and trembles. When an electrocardiogram is taken, the P-wave signal that comes out when the atrium is squeezed does not come out, and the pulse seems very irregular. This results in palpitations. These palpitations disappear after a couple of months of adjustment.
Next, with atrial fibrillation, even if the contraction function of the left ventricle is normal, sufficient blood cannot be sent throughout the body. As a result, heart failure symptoms appear in which the heart function is not complete, which causes shortness of breath and swelling of the body easily when walking quickly or climbing stairs.
Finally, blood clots occur well as blood stagnates in the left atrium, such as a small pocket attached to the left atrium. This blood clot occurs well even if atrial fibrillation lasts only two to three days, and when the blood clot falls off, a stroke occurs when the blood vessel is blocked through the left ventricle.
Atrial fibrillation is a fairly common arrhythmia in the elderly. Atrial fibrillation occurs in about 7% of stroke patients over the age of 70, and in fact, 30 to 35% of stroke patients over the age of 70 occur due to atrial fibrillation. In particular, women over the age of 75 and those with a previous history of transient cerebral ischemia or stroke, high blood pressure, diabetes, angina, myocardial infarction, and peripheral arterial stenosis are highly likely to develop stroke.
Bae Jang-hwan, director of the Circulatory Medicine and Cardiovascular Center at Good Samsun Hospital, said "In order to prevent and detect atrial fibrillation early, steady health care is essential, and the most important preventive method is to control high blood pressure because high blood pressure is an important risk factor for atrial fibrillation."It is recommended to check your blood pressure regularly, if you have high blood pressure, thoroughly manage it, and if you have irregular heartbeats or palpitations, seek cardiovascular treatment. If you are 60 years old or older, it is recommended to have an electrocardiogram every year."
"Atrial fibrillation is not just a problem with an irregular heartbeat, it is a serious disease that increases the risk of heart failure and stroke."The key to a healthy old age is to detect atrial fibrillation early through regular checkups and lifestyle management and to implement preventive treatment. If you experience palpitations or irregularities when you point out your pulse, I recommend you to see a cardiologist," he added.
