Heart health, things you may not know yet

The heart is an amazingly active organ - carrying 2,700 million beats in an average life of 75 years. Currently, coronary artery disease is one of the most fatal diseases, with 12 million deaths worldwide each year.

In Vietnam, coronary artery disease ranks fourth among the most fatal diseases. Here are the common questions about cardiovascular health.

What does Tim have?

Every minute, the heart pumps a total of 4.25 liters of blood throughout the body. In fact, the heart has two pump parts that work at the same time. The left side pumps blood through the arteries so that every cell in the body gets what it needs (oxygen, glucose, hormones, minerals, vitamins and other nutrients) to survive and grow, At the same time, waste can be removed, especially carbon dioxide (CO ₂ ), at a frequency of 70 times / minute. At the same time, the right part pumps blood to the lungs - where CO ₂ is eliminated and oxygen is absorbed into the bloodstream.

Can the heart become infected?

Have. The most common form is endocarditis (endocarditis). The disease occurs because bacteria enter the heart lining. Men are twice as likely to be infected as women. The disease is common at age over 50 and can be fatal.

Typical heart failure symptoms?

There are many signs and symptoms that indicate heart failure. Obstruction of blood circulation leads to edema of the legs, feet or abdomen. Symptoms of dyspnea can occur during exertion and even at rest. Waking up with a feeling of difficulty breathing is also a typical sign of progressive heart failure. In addition, symptoms include fatigue, angina, dizziness and weight gain.

Can myocardial infarction recur?

Have. Those who have had a heart attack, angina or stroke are more likely to get it again in the future.

Is heart failure inherited?

Have. Estimates of genetic factors can account for up to 50% of the causes of heart failure.

How does alcohol moderate help protect the heart?

Research shows that 50% of the heart's protective effect is due to its ability to increase good cholesterol (HDL). Moderate alcohol consumption can contribute to less coherent blood, making circulation more smooth, reducing the risk of heart attack or stroke. These benefits can be maximized when drinking alcohol during meals.

The risk of heart disease increases with age?

Coronary artery disease is a degenerative disease and usually occurs in old age. As the age of arteries decreases, elasticity decreases so the risk of high blood pressure and heart disease increases. Heart attack is a disease of people over 65 years old.

How much is the risk of cessation reduced?

Quitting smoking reduces nearly 40% of coronary heart disease mortality, the most common form of cardiovascular disease.

After 55 years, women have higher blood pressure than men?

Blood pressure increases with age. Although at the age of 30 and early 40, men have a higher risk of hypertension than women, but in the period of 44-55 years, the risk of becoming equal to the sexes. After age 55, women have a higher risk of high blood pressure.

Does blood pressure change when giving blood?

When giving 0.5 liters of blood, blood pressure drops and can make you dizzy. The cardiovascular system compensates for the lack of blood by increasing the heart rate and then constricting blood vessels before normalizing blood pressure. This process can take a few minutes, and that's why you need to rest after giving blood.

Can childhood obesity increase the risk of heart disease?

Have. The oversized baby physique is a very reliable predictor of heart disease later.

Does Viagra increase the risk of myocardial infarction?

When new Viagra drugs were circulated, many reports of myocardial infarction and sudden death. Later studies suggest that people with stable coronary artery disease may use the drug without increasing the risk of heart attack or death.

How much is blood pressure index acceptable?

For decades, the 140/90 index is considered an acceptable threshold. However, many studies show that people with average blood pressure of 130/80 are less likely to develop cardiovascular disease, so this index is considered the best.

Is it necessary to take life-long blood pressure medication?

Right. Most antihypertensive drugs work within 24 hours, after which they are excreted from the body. High blood pressure is a chronic disease that requires lifelong treatment.

Does drinking coffee increase the risk of cardiovascular disease?

Coffee contains caffeine stimulants that increase heart rate. After drinking, caffeine can make your heart beat fast. Caffeine in other drinks like tea, chocolate also has the same effect. If your heart is healthy, it's okay, but if you've ever had a heart attack or other cardiovascular disease, limit caffeine drinks.
