Komatsu is an ordinary office worker who just turned 29 this year. His living habits are very good. He doesn’t smoke, drink, or stay up late. Even if he gathers with friends, he arranges to go to the tea room. Such a healthy living state is a minority among contemporary young people.

But Komatsu himself did not expect that with so many healthy habits, he still encountered health crisis. At a very ordinary tea drinking party, I suddenly had chest pains without any symptoms, and there was no relief after a rest, and the headache became more and more severe. Friends were so frightened that they rushed him to the hospital. After examination, he was found to have a large area of myocardial infarction.

This result shocked my friends. Why did a guy with such a healthy lifestyle suffer from a heart attack? Komatsu’s attending doctor gave an explanation: During the examination, it was found that his low-density lipoprotein cholesterol was as high as 8.1mmol/L, which was seriously exceeding the standard, so it caused a myocardial infarction.

Why does high LDL cholesterol cause myocardial infarction? Let’s find out.

Excessive bad cholesterol causes myocardial infarction?

Low-density lipoprotein cholesterol is also called bad cholesterol.This type of cholesterol is easily oxidized in blood vessels, and then these oxides are deposited on the walls of blood vessels , the formation of vascular plaque, induced atherosclerosis. If the low-density lipoprotein cholesterol exceeds the standard for a long time, the blood vessels are easily blocked by the blood vessel plaque. Once the blood vessels are blocked, it is easy to induce myocardial infarction.

According to the global disease burden data, the Chinese Center for Disease Control and Prevention estimated that the number of deaths caused by high LDL cholesterol in my country accounted for 8.25% of the total number of deaths, of which more than 70 10,000 people die of heart disease. This also means that LDL cholesterol is too high, seriously endangering our heart health, so we must use the right method to reduce the content of this cholesterol.

So, what to do? “Nature” has an answer.

《Nature》: Caffeine can lower “bad cholesterol”

Coffee is still common in life, but many people do not know that coffee can help people Reduce LDL cholesterol levels. Nature has published a 16-year follow-up study examining the beneficial effects of coffee on the human body.

The study on the coffee habits of more than 500,000 people across Europe found that coffee drinking more people have a lower mortality rate than people who don’t drink coffee. Regular consumption of coffee, caffeine in coffee can reduce the level of PCSK9 protein in the blood, which can block SREBP2 Activation of protein, thereby reducing the content of low-density lipoprotein cholesterol, and then play a role in preventing cardiovascular disease.

Caffeine is good for heart health, and some people think that it is better to drink a cup of coffee a day for their heart. But not long ago, a study in the United States raised questions about coffee.

Caffeine lowers cholesterol, but coffee damages the kidneys, what should I do?

Although coffee can reduce the content of bad cholesterol, it should not be drunk too much. Excessive drinking will bring a lot of harm. A study published in the Journal of the American Society of Clinical Nephrology found that changes in the levels of two metabolites in coffee were associated with an increased risk of chronic kidney disease.

Research scholars from Johns Hopkins University in the United States studied the relationship between chronic kidney disease and coffee and found that there were changes in the levels of 20 metabolites and coffee intake There are two components, which are metabolites of preservatives, which can cause certain damage to the kidneys, and their levels are positively correlated with coffee intake.Meaningdrinking coffee may be potentially harmful to kidney health.
