In order to work properly, the heart requires adequate oxygen-rich blood intake. Blood for this organ will be channeled through two large vessels called coronary vessels. Sitting winds occur when the coronary arteries are narrowed.
Based on the things that can trigger constriction of coronary vessels, the sitting wind is divided into three types, namely:
- The Angina steady. Physical activity (such as exercise) is the trigger for this condition. When a person does exercise, his heart will need more blood intake. This intake will not be fulfilled if the coronary vessels experience blockage or constriction. Stable seated wind attacks can also be triggered by some other things, such as smoking, stress, overeating, and cold air.
- The Angina unstable. This condition can be triggered by fat deposits or blood clots that reduce or block the flow of blood to the heart. Unlike the Angina stable, the pain due to Angina unstable will still exist even though the patient is already rested and taking the drug. If left unchecked, an unstable wind seizure may develop into a heart attack.
- The Angina variant (Prinzmetal wind sits). In this case the heart arteries narrowed temporarily from spasm. The Angina variant can happen anytime, even when someone is resting. Symptoms are often severe. Temporary narrowing of the arteries causes the blood supply to the heart to decrease and pain arise. Even so, the symptoms of Angina variants can be appeased with drugs.
A number of factors can increase the risk of getting wind seated. Some of these factors include:
- High cholesterol. High cholesterol levels in the body of a person potentially accumulate in the blood vessels. If this happens, of course the blood will be difficult to flow into the heart.
- Have diabetes. High sugar levels due to diabetes, can damage artery walls. In addition, diabetes can also increase cholesterol levels in the body.
- Hypertension. If the blood flow is blocked, the heart will pump stronger and increase the pressure for the blood to flow. If this continues, the high pressure may damage the arterial wall or cause hardening of the vessel.
- Stress. When we experience stress, the body will produce a number of hormones that can narrow the blood vessels. In addition, stress can also increase blood pressure.
- Obesity. People who are obese will be susceptible to a number of conditions that can increase the risk of getting a sitting wind, such as diabetes, hypertension, and high cholesterol.
- Smoke. This activity can damage the arterial wall and cause the accumulation of cholesterol so that the blood will be difficult to carry oxygen to be circulated.
- History. If we have had heart disease or have a family that has such a history, then we will also be at high risk of a sitting wind.
- Less exercise. People who lack exercise are at increased risk of wind sitting because they are susceptible to obesity, hypertension, high cholesterol, and diabetes, which in turn increases the risk of developing angina.
- Age. Older people are more at risk of wind from sitting than young people because the blood vessels will harden and lose their flexibility with age. Especially for men, this increased risk starts at age 45 years, whereas in women starting at age 55 years.
