Sleep is a period of rest that alternates with wakefulness. You have internal body clocks that control when you are awake and when your body is ready for sleep. These clocks have cycles of approximately 24 hours. The clocks are regulated by multiple factors, including light, darkness, and sleep schedules. Once asleep, you cycle through the stages of sleep throughout the night in a predictable pattern.

If you vape, protect yourself by storing loose batteries in a case and away from metal objects.

Angina is not a heart attack, but it is a signal that you are at greater risk of having a heart attack. The risk is higher if you have unstable angina. For this reason, it is important that you receive follow-up care, monitor your condition, and understand your condition so you know when to get medical help. Your doctor may recommend heart-healthy lifestyle changes and cardiac rehabilitation to help manage angina.

Your doctor will decide on a treatment approach based on the type of angina you have, your symptoms, test results, and risk of complications. Unstable angina is a medical emergency that requires immediate treatment in a hospital. If your angina is stable and your symptoms are not getting worse, you may be able to control your angina with heart-healthy lifestyle changes and medicines. If lifestyle changes and medicines cannot control your angina, you may need a medical procedure to improve blood flow and relieve your angina.

Your doctor may diagnose angina based on your medical history, a physical exam, and diagnostic tests and procedures. These tests can help assess whether you need immediate treatment for a heart attack. Some of these tests may help rule out other conditions.

Signs and symptoms vary based on the type of angina you have and on whether you are a man or a woman. Angina symptoms can differ in severity, location in the body, timing, and how much relief you may feel with rest or medicines. Since symptoms of angina and of heart attack can be the same, call 9-1-1 if you feel chest discomfort that does not go away with rest or medicine. Angina can also lead to a heart attack and other complications that can be life-threatening.

Typically, doctors screen for angina only when you have symptoms. However, your doctor may assess your risk factors for ischemic heart disease every few years as part of your regular office visits. If you have two or more risk factors, then your doctor may estimate the chance that you will develop ischemic heart disease, which may include angina, over the next 10 years.

You may have an increased risk for angina because of your age, environment or occupation, family history and genetics, lifestyle, other medical conditions, race, or sex.
