Q9. The blood vessel which was damaged before can recover. (A) True (B) False A9. (A) True It had been thought that damaged blood vessels could not recover, but according to the newest research, it turned out that recovering was possible. The most inside layer of the blood vessel can recover at a certain level by the improvement of the lifestyle. The foods which are expected to help the damaged blood vessels recover are miso, cheese and onions in addition to balanced meals. LTP (Lactotripeptides) is a kind of amino acids recently discovered contained in miso and cheese and it is expected to lower blood pressure and prevent arteriosclerosis. Quercetin is a flavonol that prevent active oxygen damage the blood vessel with antioxidant action and also makes the blood flow better. Quercetin is contained in onions a lot. If you peel the skin of onions and place them under the sun for about a week, the amount of quercetin becomes 3 times more. So a recommended recipe is miso soup with onions and cheese.

Q5. Why do stroke and heart attack occur most in winter?
(A) Because blood vessels contract with cold. (B) Because blood flow becomes faster with cold. A5. (A) Because blood vessels contract with cold. Blood plays a very important roll to control the body temperature. For example, when you go to a warm place, your body tries to release heat enlarging the blood vessels to lower the body temperature. On the contrary, when you go to a cold place, your body tries not to release heat contracting the blood vessels to keep the body temperature. This is similar to the relationship between cars and roads. Assuming the warm place is 3 lanes and the cold place is 1 lane, when cars come from 3 lanes to 1 lane, traffic jam happens at 1 lane. That is like blood tends to be clogged if it is cold because the blood vessel becomes narrower. That is why stroke and heart attack tend to occur more in January and February (winter). Q6. Who has the risk to have stroke or heart attack (myocardial infarction) during sleep? (A) A person who snores (B) A person who talks in his or her sleep (C) A person who often tosses and turns A6. (A) A person who snores Q7. Why does the person who snores during sleep have the risk? A7. Because blood pressure goes up and down repeatedly, applying a burden to the blood vessels. Rapid rise of blood pressure applies a burden to the blood vessels and there is a high possibility that it damages the blood vessels. A person who snores frequently has a high possibility to cause sleep apnea syndrome. When snoring starts, blood pressure goes up and when snoring stops, blood pressure goes down so every time snoring starts and stops, snoring puts a tax on the blood vessels. Q8. Heart attack (Myocardial infarction) tends to occur in the morning, especially within an hour after waking up. What are dangerous habits if they are done especially on cold morning? A8. Going to the bathroom, washing one’s face, taking out the garbage, taking the dog for a walk, jogging, etc. So what are the reasons that they are dangerous habits? First, cold morning makes the blood vessels contract, leading to the rise of blood pressure. That is why it is dangerous. Straining to defecate leads to the rise of blood pressure. If you jog or take the dog for a walk dressed lightly on a cold morning, blood pressure goes up by coldness and exercises. So when you take the dog for a walk, it is important to protect yourself against the cold wearing a scarf and a coat. It is very dangerous to let your guard down, thinking it is OK because it is very short time. Stroke and heart attack occur most in winter so let's learn the basic information from the following quiz.
Q1. What disease are both stroke and heart attack (myocardial infarction)? A1. They are blood vessels’ diseases. Q2. What is clogged when myocardial infarction and cerebral infarction occur? (A) Cholesterol (B) Blood clots A2. (B) Blood clots A blood clot is something similar to congealed nosebleed, formed in the blood vessel. The cells in our body can work with oxygen and nutrition from the blood vessels. If the blood vessels which are passages to deliver oxygen and nutrition are clogged by blood clots, the cells die because the required energy is not delivered. Q3. How long will it be if all the blood vessels are connected? A3. About 100000 km (about 62000 miles) (distance of earth 2.5 rounds) For example, if there is a road of earth 2.5 rounds, it is not so unusual that there is a traffic jam or an accident somewhere. Similarly, it is not a surprise that a blood clot happens in the blood vessels at any moment. Q4. When you have stroke or myocardial infarction, there are subjective symptoms. (A) True (B) False A4. (B) False There are signs but no obvious subjective symptoms. So people feel it suddenly occurred. The sign of heart attack is such as when you climb up stairs, you feel pressure and pain in your chest. The sign of stroke is such as temporary tingling sensation in your hands and feet or speaking inarticulately. |
