cholesterol day of procedure tips

Overview

This guide is for people who are having a procedure to help manage high cholesterol and its effects on the heart and circulation. High cholesterol means you have too much of a fatty substance called cholesterol in your blood. Over time, this can build up inside your arteries (the blood vessels that carry blood from your heart around your body) and narrow them. This can increase your risk of heart attacks and strokes. A procedure — such as an angiogram, angioplasty, or stent placement — may be recommended to open blocked or narrowed arteries and improve blood flow. This article gives you simple tips for the day of that procedure, so you know what to expect and how to prepare.

Many people with high cholesterol eventually need a procedure to treat narrowed or blocked arteries. Artery blockages from cholesterol are one of the most common heart problems worldwide. Procedures like angiograms and angioplasties are performed routinely and are generally safe.

This advice is for anyone with high cholesterol who is scheduled for a heart or circulation procedure, such as an angiogram, angioplasty, or stent placement. It may also apply to people having a carotid endarterectomy or other surgery to remove cholesterol buildup. Older adults, people with diabetes, and those with a family history of heart disease are more likely to need these procedures.

Symptoms

Common symptoms

• Chest pain or discomfort (angina), especially during activity
• Shortness of breath
• Pain, numbness, or weakness in your legs when walking (peripheral artery disease)
• Fatigue
• Palpitations (feeling like your heart is pounding or fluttering)

Symptoms in children

• High cholesterol in children usually has no symptoms, but it can sometimes cause yellowish, fatty bumps on the skin called xanthomas.
• A doctor might check cholesterol levels if there is a strong family history of early heart disease.

Symptoms in older adults

• Chest pain may be less severe or feel like indigestion or pressure.
• Shortness of breath with activity is common.
• Fatigue or weakness that is new or getting worse.

Causes

Main causes

• High levels of low-density lipoprotein (LDL) cholesterol — often called 'bad' cholesterol — in your blood
• Low levels of high-density lipoprotein (HDL) cholesterol — the 'good' cholesterol that helps remove excess cholesterol
• A diet high in saturated and trans fats
• Lack of physical activity
• Being overweight or obese
• Smoking or using tobacco products

Risk factors

• Family history of high cholesterol or early heart disease
• Age (risk increases as you get older)
• Uncontrolled diabetes
• High blood pressure
• Chronic kidney disease
• Certain conditions like an underactive thyroid or some liver diseases

When to see a doctor

See a doctor urgently if:

• If you have any of the emergency symptoms listed above, call your local emergency number immediately — do not wait.
• If you are scheduled for a procedure and you develop a fever, cough, or feel very unwell the day before or day of the procedure, tell your healthcare team right away.

Book a routine appointment if:

• If you have high cholesterol and have not had a procedure before, see your doctor to discuss treatment options if you experience chest pain, shortness of breath, or other symptoms.
• If you have a follow-up appointment after a procedure, attend it as scheduled to check your recovery and cholesterol levels.

Diagnosis

High cholesterol is diagnosed with a simple blood test called a lipid panel. This test measures your total cholesterol, LDL cholesterol, HDL cholesterol, and triglycerides (another type of fat in your blood). Before a procedure, your doctor will also use imaging tests like an angiogram to see how narrowed or blocked your arteries are.

Tests that may be done

• Lipid panel (blood test)
• Angiogram — a special X-ray with dye to look at blood flow in your arteries
• CT scan or MRI of the heart and blood vessels
• Stress test — seeing how your heart works during exercise or medicine that makes your heart work harder

What to expect at your appointment

On the day of your procedure, you will be asked to arrive at the hospital or clinic at a specific time. You will likely be told not to eat or drink anything for several hours beforehand. You will change into a hospital gown and a nurse will check your blood pressure, pulse, and oxygen level. You may have an IV (small tube) put into a vein in your arm to give you fluids and medicine. The procedure itself is usually done while you are awake but relaxed with medicine (sedation). The area where the doctor will work (often your groin or wrist) will be numbed. You might feel some pressure but not sharp pain. The procedure usually takes one to two hours. Afterward, you will rest in a recovery area, and the team will monitor you.

Treatment

Treatment for high cholesterol focuses on lowering your cholesterol levels to reduce the risk of heart attack and stroke. This includes lifestyle changes, medications, and sometimes procedures to open blocked arteries. The day of the procedure is one step in a long-term plan to manage your cholesterol and protect your heart.

Self-care at home

• Follow the fasting instructions exactly — usually nothing to eat or drink for 6 to 8 hours before the procedure. (Your team will tell you exactly when to stop.)
• Take only the medications your doctor tells you to take on the morning of the procedure. Bring a list of all your medicines and any allergies.
• Wear comfortable, loose-fitting clothing and leave jewelry and valuables at home.
• Arrange for a responsible adult to drive you home if you are not staying overnight. You will not be able to drive yourself because of the sedation.
• Bring a list of questions or concerns you have — it's normal to feel nervous.
• Avoid smoking or using tobacco products for at least 24 hours before the procedure, if possible.
• Tell your healthcare team if you have any new symptoms, like a cold or fever, or if you think you might be pregnant.

Medical treatments

Doctors usually prescribe medicines to help lower cholesterol, such as statins, ezetimibe, or PCSK9 inhibitors. These are not recommended by name here — your doctor will choose the right one for you. You may also be given blood-thinning medicines before or after the procedure to prevent clots. Your healthcare team will explain what you need to take and when. On the day of the procedure, you may receive extra medicine through your IV to keep you comfortable and to prevent blood clots.

When is surgery considered?

If a procedure like angioplasty (using a tiny balloon to open the artery) is not enough, or if blockages are severe, you may need bypass surgery. This is open-heart surgery where the doctor takes a healthy blood vessel from another part of your body and connects it around the blocked artery. Your doctor will discuss this option if it is right for you.

Living with this condition

After your procedure, you will need time to recover. You may have a small bandage or pressure device on your wrist or groin where the catheter was inserted. Most people can return to light activities within a few days to a week. Your doctor will give you specific instructions about when you can drive, go back to work, and exercise. It is important to take your medicines as prescribed and attend follow-up appointments.

Lifestyle tips

• Follow a heart-healthy diet low in saturated fat, trans fat, and salt — eat plenty of fruits, vegetables, whole grains, and lean proteins.
• Get regular physical activity — aim for at least 150 minutes of moderate exercise per week, but follow your doctor’s advice on when to start after the procedure.
• If you smoke, get support to quit. Smoking damages your blood vessels and raises cholesterol.
• Limit alcohol to no more than 1 drink per day for women and 2 for men, if you drink at all.
• Manage stress through relaxation techniques, hobbies, or talking to someone you trust.

Diet and exercise

A heart-healthy diet includes foods like oats, nuts, oily fish (such as salmon), beans, and vegetables. Avoid fried foods, processed meats, and full-fat dairy. After your procedure, start with gentle walking and gradually increase as your doctor allows. If you have chest pain or shortness of breath while exercising, stop and tell your doctor.

Mental health and emotional wellbeing

Having a procedure for your heart can be stressful and may cause anxiety or depression. It is normal to feel worried about your health or the recovery. Talk to your doctor or a counselor if you feel overwhelmed. Taking care of your mental health is as important as taking care of your physical health.

Prevention

High cholesterol itself cannot always be prevented, especially if it runs in your family. But you can lower your risk of needing a procedure by managing your cholesterol early. Eat a healthy diet, stay active, maintain a healthy weight, and do not smoke. If you already have high cholesterol, taking your medicines as prescribed and attending your check-ups can help prevent blockages from getting worse.

Vaccines

There are no vaccines to prevent high cholesterol or heart procedures. However, getting the flu vaccine and pneumonia vaccine is recommended for people with heart disease, as infections can put extra stress on your heart.

Screening programmes

Most adults should have their cholesterol checked every 4 to 6 years starting at age 20. If you have risk factors like diabetes or a family history of heart disease, you may need more frequent checks. After a procedure, your doctor will check your cholesterol regularly to see if your treatment is working.

Complications

If left untreated

• Heart attack (when a blocked artery cuts off blood flow to part of your heart)
• Stroke (when a blocked artery cuts off blood flow to part of your brain)
• Peripheral artery disease (narrowed arteries in your legs, causing pain and difficulty walking)
• Kidney damage from narrowed arteries
• Angina (chest pain that can get worse over time)

Long-term outlook

The outlook for people with high cholesterol who have a procedure is very good. The procedure can restore blood flow and relieve symptoms. With lifestyle changes and medicines, most people can manage their cholesterol and reduce the risk of future problems. Recovery takes time, but many people return to their normal activities and enjoy a better quality of life. Your healthcare team will support you every step of the way.
