How to Diagnose High Cholesterol and Treat Based on Current Standards of Care

Diagnosis of high cholesterol is typically done through a blood test called a lipid panel or lipid profile. This test measures the levels of total cholesterol, low-density lipoprotein (LDL) cholesterol, high-density lipoprotein (HDL) cholesterol, and triglycerides in the blood. According to the National Institutes of Health (NIH), high cholesterol is defined as a total cholesterol level of 240 milligrams per deciliter (mg/dL) or higher, an LDL cholesterol level of 130 mg/dL or higher, and/or a triglyceride level of 150 mg/dL or higher.

There are several risk factors for developing high cholesterol, including a family history of high cholesterol, obesity, lack of physical activity, and a diet high in saturated and trans fats. The American College of Cardiology (ACC) and the American Heart Association (AHA) have developed guidelines for identifying individuals at high risk for cardiovascular disease, which include assessment of cholesterol levels. According to the ACC/AHA, individuals with an LDL cholesterol level of 190 mg/dL or higher are considered to be at very high risk for cardiovascular disease and should be treated aggressively.

The current standard of care for treating high cholesterol in the United States is lifestyle modification and, if necessary, medication. Lifestyle modification includes eating a diet low in saturated and trans fats, increasing physical activity, and maintaining a healthy weight. The ACC/AHA recommends that individuals at high risk for cardiovascular disease should aim for an LDL cholesterol level of less than 70 mg/dL.

Medications used to lower cholesterol include statins, which are the most effective and widely prescribed class of cholesterol-lowering drugs. Statins work by inhibiting the enzyme HMG-CoA reductase, which is responsible for producing cholesterol in the liver. Other classes of medications that can be used to lower cholesterol include bile acid sequestrants, nicotinic acid, and fibric acid derivatives.

In addition, the FDA has approved a new class of drugs called PCSK9 inhibitors, which have shown to be effective in significantly lowering LDL cholesterol levels. PCSK9 inhibitors are given as a subcutaneous injection and are typically used in patients who do not achieve their cholesterol goals with lifestyle modification and statins or those who have genetic disorders that cause very high cholesterol levels.

In conclusion, high cholesterol is a major risk factor for cardiovascular disease and is typically diagnosed through a blood test called a lipid panel. The current standard of care for treating high cholesterol includes lifestyle modification and, if necessary, medication such as statins and PCSK9 inhibitors. It’s important for physicians to follow the guidelines set by the ACC and AHA in identifying and managing high-risk patients.
