This deprivation is called ischemia. The medical term for a heart attack is myocardial infarction. According to the American Heart Association , someone in the United States has a heart attack roughly every 34 seconds. A heart attack is a medical emergency. Peripheral artery disease PAD can occur when plaque builds up in the walls of the arteries.
This will block the flow of blood in the arteries that supplies blood to the kidneys, arms, stomach, legs, and feet. As PAD progresses, symptoms occur more frequently and even occur when you are at rest.
Later symptoms that may occur because of reduced blood flow include:. High cholesterol is very easy to diagnose with a blood test called a lipid panel. Your doctor will take a sample of blood and send it to a laboratory for analysis.
Your doctor will ask that you do not eat or drink anything for at least 12 hours prior to the test. The American Heart Association recommends having your cholesterol levels checked every 4 to 6 years if you are a healthy adult over the age of You may need to have your cholesterol checked more often if you are at an increased risk of high cholesterol.

Without treatment, high cholesterol may lead to many health issues, including heart attack and stroke. High cholesterol rarely causes symptoms in the beginning. Learn how this screening could potentially save your life. Eating too many foods that are high in cholesterol, saturated fats, and trans fats may increase your risk of developing high cholesterol. Living with obesity can also increase your risk. Other lifestyle factors that can contribute to high cholesterol include inactivity and smoking.
Your genetics can also affect your chances of developing high cholesterol. Genes are passed down from parents to children. Certain genes instruct your body on how to process cholesterol and fats. If your parents have high cholesterol, you may be at a greater risk of having it too. In rare cases, high cholesterol is caused by familial hypercholesterolemia. This genetic disorder prevents your body from removing LDL.
According to the National Human Genome Research Institute , most adults with this condition have total cholesterol levels above milligrams per deciliter and LDL levels above milligrams per deciliter. Other health conditions, such as diabetes and hypothyroidism , may also increase your risk of developing high cholesterol and related complications.
If your levels of LDL cholesterol are too high, it can build up on the walls of your arteries. This buildup is also known as cholesterol plaque. This plaque can narrow your arteries, limit your blood flow, and raise your risk of blood clots. If a blood clot blocks an artery in your heart or brain, it can cause a heart attack or stroke.
This helps prevent cholesterol plaque from building up in your arteries. When you have healthy levels of HDL cholesterol, it can help lower your risk of blood clots, heart disease, and stroke. Triglycerides are another type of lipid. While your body uses cholesterol to build cells and certain hormones, it uses triglycerides as a source of energy. When you eat more calories than your body can use right away, it converts those calories into triglycerides.
It stores triglycerides in your fat cells. It also uses lipoproteins to circulate triglycerides through your bloodstream. If you regularly eat more calories than your body can use, your triglyceride levels may become too high. This can raise your risk of several health problems, including heart disease and stroke.
Your doctor can use a simple blood test to measure your triglyceride level, as well as your cholesterol levels. If you have a history of high cholesterol or other risk factors for cardiovascular disease, your doctor may encourage you to get your cholesterol levels tested more often.
Your doctor can use a lipid panel to measure your total cholesterol level, as well your LDL cholesterol, HDL cholesterol, and triglyceride levels. Your total cholesterol level is the overall amount of cholesterol in your blood. If your levels of total cholesterol or LDL cholesterol are too high, your doctor may diagnose you with high cholesterol. If your doctor does prescribe you medication, different factors may influence the type of medication they recommend.
With this in mind, most physicians use generalized measurements to decide on treatment plans. They may categorize these measurements as desirable, borderline high, or high cholesterol. According to the National Library of Medicine , the total cholesterol of most adults can be categorized as:. A person with high cholesterol levels often has no signs or symptoms, but routine screening and regular blood tests can help detect high levels.
A person who does not undergo testing may have a heart attack without warning, because they did not know that they had high cholesterol levels. Regular tests can help to reduce this risk. A report from Harvard Health has identified 11 cholesterol-lowering foods that actively decrease cholesterol levels:.
Various low cholesterol recipe books are available to purchase online. HDL levels should be kept higher. People who wish to reduce their cholesterol levels or maintain a suitable level can make four major lifestyle decisions.
Since , guidelines on reducing or preventing high cholesterol have focused on addressing lifestyle risks, even at a young age. Taking these factors into consideration will lead to a more personalized approach to the treatment and prevention of high cholesterol levels.
For a person with high cholesterol levels, drug treatment will depend on their cholesterol level and other risk factors. Recommendatoins usually start with diet and exercise, but people with a higher risk of a heart attack may need to use statins or other medications.
Statins are the leading group of cholesterol-lowering drugs. The statins available on prescription in the United States include:. In , researchers noted that a new drug, ezetimibe, can significantly reduce the risk of a major cardiovascular event in people with a high risk of such events.
Etezimibe reduces lipid levels by limiting the absorption of cholesterol in the intestine. There is evidence that these drugs are effective at reducing cholesterol levels, especially when a person uses them with ezetimibe. If a person has already had a cardiovascular event, such as a heart attack, a doctor may recommend using ezetimibe as well as a statin. For those at very high risk, the guidelines also recommend adding a PCSK9 inhibitor.
However, the guidelines also note that PCSK9 inhibitors are expensive, and insurance companies may not cover their cost. For this reason, this option is likely to be only for those with a very high risk. A person should not stop taking a statin without speaking to a doctor, as they may increase their risk of cardiovascular problems.
Randomized, controlled clinical trials have not produced enough evidence to support treatment to a specific target. Guidelines published in consider this calculator and essential tool for assessing cholesterol levels and their risk.
