The Framingham Heart Study and the epidemiology of cardiovascular disease: a historical perspective
Key result
Framingham Heart Study establishes major CV risk factors across 65 years of epidemiology.
- n=5,209
Why the study?
To mark 65 years since the Framingham Heart Study began, this article reviews the events leading to its founding and outlines selected contributions to cardiovascular epidemiology.
Key Points
- To describe the historical events prompting the founding of the Framingham Heart Study, notably President Franklin D. Roosevelt's fatal cardiovascular illness, and review its major epidemiologic contributions.
- Examined archives of the Framingham Heart Study at the National Heart, Lung, and Blood Institute and Harvard University's collection of Franklin D. Roosevelt's presidential files.
- Conducted literature searches across PubMed and Google Scholar from January 1947 to March 2013 for English-language publications relating to cardiovascular risk factors and outcomes.
- Cardiovascular disease caused 1 in 2 deaths in the United States during the 1940s, while global circulatory deaths increased by one-third between 1990 and 2010.
- President Roosevelt experienced an unaddressed rise in blood pressure from 140/100 mm Hg in 1932 to 300/190 mm Hg at his death from cerebral hemorrhage in 1945, reflecting the era's clinical limitations.
- Passage of the National Heart Act in 1948 allocated a $500,000 seed grant to establish a 20-year cohort study, leading to the examination of the first participant on October 11, 1948.
Structured PICO
P
Population
A historical review of the Framingham Heart Study, which originally recruited 5,209 adults aged 28-62 years to longitudinally study the epidemiology and risk factors of cardiovascular disease.
This historical review highlights how the Framingham Heart Study established the concept of cardiovascular risk factors and catalyzed the shift toward preventive cardiology.
Limitations
- Early critics expressed uncertainty about whether study participants represented Americans in general
- Family-based approach was initially questioned

“The founders of Framingham and similar studies were obviously making an investment for the future. They had a fundamental understanding that collecting clinical observations in people over time would be extremely valuable for biomedical research.”
PAPhilip A. WolfProfessor of neurology and medicine, Boston University
“Framingham changed the focus of health care from treating sick people to trying to prevent healthy people from getting sick. The study identified the risk factors for diseases of the heart and blood vessels—the idea that hypertension, high cholesterol, and, I believe, cigarette smoking were key risk factors for developing coronary disease.”
“This study is their study, and we could not have accomplished all that we've learned about the risk factors for heart disease, the occurrence of heart disease, all of the genetic and molecular factors related to heart disease, without their willingness to come in for the testing and be forward-thinking about all of these new areas of research.”
Implication
Sustains prevention emphasis via risk factor awareness in practice; leaves open how these insights translate to modern diverse populations.
Abstract
On October 11, 2013, the Framingham Heart Study will celebrate 65 years since the examination of its first participant in 1948. During this period, the study has provided substantial insight into the epidemiology of cardiovascular disease and its risk factors. The origin of the study is closely linked to the cardiovascular health of President Franklin D. Roosevelt and his premature death from hypertensive heart disease and stroke in 1945. The present article describes the events leading to the founding of the Framingham Heart Study, and provides a brief historical overview of selected contributions from the study.

Mahmood et al. (2013) conducted a review in Cardiovascular disease (n=5,209). Longitudinal epidemiological observation was evaluated. The Framingham Heart Study has provided foundational insights into cardiovascular disease epidemiology over 65 years, establishing the concept of risk factors such as hypertension, hyperlipidemia, and diabetes.
