The History of Lipid & Cholesterol Discovery

The history of cardiac care spans centuries. Understanding lipids transformed modern medicine. Discover the key milestones below.

Early Anatomy & Blood Circulation

• Cave drawings: First heart diagram found in Spain.
• 1555: Andreas Vesalius disproved liver-centric blood theories.
• 1559: Riva di Trento described coronary arteries.
• 1628: William Harvey proved heart pumps blood.

The Cholesterol Timeline

• 1758: Cholesterol first isolated from gallstones by Francois Poulletier de La Salle.
• 1815-1838: Named "cholesterol" by Michel Eugene Chevreul, later found in human blood.
• 1932-1964: Structure defined by Adolf Windaus; synthesis mapped by Dr. Konrad Bloch.

Atherosclerosis & Lipoproteins

• 1850s: Richard Quain and Rudolf Virchow defined atherosclerosis and fatty vascular deposits.
• 1951: Elevated LDL identified in heart patients.
• 1973-1985: Joe Goldstein, Michael Brown, and team identified LDL pathways and receptor mechanisms.

The Diet-Heart & Lipid Hypothesis

• 1913: Nikolai Anitschkow linked cholesterol to atherosclerosis in rabbits.
• 1950s-1970s: Ancel Keys proposed the 7-country study, sparking debate over fat vs. sugar (John Yudkin) in diet-heart links, leading to the 1977 dietary guidelines.

Evolution of Lipid Testing

• 1934: First cholesterol blood tests.
• 1950s-1969: John Gofman isolated plasma lipoproteins, leading to the Friedewald formula for calculating LDL.

Breakthroughs in Cholesterol Treatment

• 1955: High-dose niacin found to lower cholesterol.
• 1976-1987: Akira Endo isolated the first HMG-CoA inhibitor, leading to the 1987 approval of Lovastatin.
• 1997-2008: Ezetimibe developed; JUPITER trial highlighted the role of inflammation and CRP.

Frequently Asked Questions (FAQs)

Who discovered cholesterol and when?

French physician François Poulletier de la Salle first isolated cholesterol in solid form from gallstones in 1758. In 1815, French chemist Michel Eugène Chevreul purified the sterol and officially named it "cholesterol" (from the Greek chole for bile and stereos for solid).

When was the link between cholesterol and heart disease discovered?

The link was first suggested in 1854 when Dr. Rudolf Virchow described atherosclerosis as an arterial clog caused by excess cholesterol deposition. Later, in 1913, scientist Nikolai Anitschkow definitively established the lipid hypothesis by feeding cholesterol to rabbits and inducing plaque formation.

When were HDL and LDL cholesterol identified?

Doctors David Barr, Edward Russ, and Howard Eder first noted in 1951 that heart disease patients had elevated low-density lipoprotein (LDL) and decreased high-density lipoprotein (HDL) levels. The formal measurement formula (Friedewald formula) to calculate LDL based on total cholesterol, HDL, and triglycerides was developed in 1969. 

Who won the Nobel Prize for cholesterol research?

Several scientists won the Nobel Prize for charting cholesterol metabolism:

• 1927: Adolf Windaus and Heinrich Wieland for discovering the chemical structure of cholesterol and bile acids.
• 1964: Konrad Bloch and Feodor Lynen for mapping the complex cholesterol synthesis and fatty acid pathways.
• 985: Michael Brown and Joseph Goldstein for discovering the LDL receptor pathway and its genetic role in hypercholesterolemia.

When was the first cholesterol-lowering statin drug invented?

In 1976, Japanese biochemist Akira Endo isolated the first HMG-CoA reductase inhibitor (Compactin) from the fungus Penicillium citrinum. This breakthrough directly led to the approval of Mevacor (lovastatin) in 1987 as the world’s first commercial statin drug.
