High cholesterol, also known as hyperlipidemia, is a condition in which blood cholesterol levels are elevated. Cholesterol is an essential fatty substance, but excess cholesterol can lead to plaque buildup in the arteries, contributing to coronary artery disease (CAD), heart attack, stroke, and peripheral artery disease (PAD). At Premier Cardiology, our team focuses on identifying, managing, and treating high cholesterol to prevent cardiovascular complications and improve long-term heart health.
Causes of High Cholesterol
High cholesterol can be caused by a combination of genetic, lifestyle, and medical factors:
- Primary (genetic) hypercholesterolemia – Inherited conditions causing elevated cholesterol from birth
- Secondary hypercholesterolemia – Resulting from lifestyle or other medical conditions such as diabetes or hypothyroidism
Risk Factors
- Poor diet high in saturated fats and trans fats
- Sedentary lifestyle
- Obesity
- Smoking
- Excessive alcohol consumption
- Age and gender
- Family history of heart disease or high cholesterol
Symptoms of High Cholesterol
High cholesterol typically has no symptoms and is often detected during routine blood tests. Severe or long-standing high cholesterol can lead to complications that may present as:
- Chest pain
- Shortness of breath
- Fatigue
- Numbness or pain in extremities due to PAD
- Heart attack or stroke in severe cases
Because high cholesterol is often silent, regular screening is essential, especially for individuals with risk factors like High Blood Pressure or Obesity.
Diagnosis
Diagnosis involves a combination of blood tests and assessments of cardiovascular health:
- Lipid panel – Measures total cholesterol, LDL (“bad” cholesterol), HDL (“good” cholesterol), and triglycerides
- EKG – Checks heart rhythm abnormalities
- Echocardiogram – Evaluates heart structure and function
- CT Scan / Calcium Scoring – Detects arterial plaque buildup
- Stress Test – Determines if reduced blood flow affects heart performance
Treatment Options
Treatment for high cholesterol aims to lower LDL cholesterol, raise HDL cholesterol, and reduce the risk of cardiovascular events.
Lifestyle Modifications
- Heart-healthy diet rich in fruits, vegetables, whole grains, and lean proteins
- Reduce intake of saturated fats, trans fats, and dietary cholesterol
- Regular physical activity
- Weight management
- Smoking cessation
- Limiting alcohol consumption
Medications
When lifestyle changes alone are not sufficient, medications may include:
- Statins – Reduce LDL cholesterol and stabilize arterial plaque
- Ezetimibe – Lowers cholesterol absorption in the intestines
- PCSK9 inhibitors – Advanced therapy for patients with severe hypercholesterolemia
- Bile acid sequestrants – Help remove cholesterol from the body
Monitoring and Follow-Up
Ongoing monitoring of cholesterol levels is essential. We recommend regular blood tests, lifestyle reassessment, and follow-up visits to help prevent CAD, heart attack, or stroke.
Preventing Complications
Effectively managing high cholesterol reduces the risk of coronary artery disease, heart attack, stroke, and peripheral artery disease. Combining lifestyle changes with medication, when appropriate, offers the best long-term outcomes and supports overall cardiovascular health.
