Charleston Heart Study

Origins of the Charleston Heart Study

heart

On February 1, 1960, the Charleston Heart Study began under the direction of Dr. Edwin Boyle Jr. It marked the beginning of a forty-year survey of heart disease and atherosclerosis (a hardening of the arteries) among Charleston County, South Carolina residents that was known as the Charleston Heart Study (hereafter CHS).

Charleston County in 1960

At the time of the 1960 U.S. Census, Charleston County was one of the largest counties in South Carolina in both population and physical size. The population totaled 216,382 consisting of 70,775 white males, 66,674 white females, 37,284 black males and 41,204 black females.

South Carolina ranked highest in the nation for heart disease related deaths. White men in Charleston had death rates 40% higher than white men in the rest of the United States. The younger white women’s death rate was 50-100% higher, and for older black women ages 55-64 the death rate was 70% higher. Black men in the range of 45-54 years had a 40% higher death rate than the national rate.

Curious as to the reasons for this, Dr. Edwin Boyle Jr. initiated the Charleston Heart Study in cooperation with the Charleston County Medical Society, local and state health departments, the South Carolina Heart Association, and the U.S. Public Health Service.

Edwin Boyle Jr., MD was born in Sumter, South Carolina, on September 27, 1923, to Edwin Boyle Sr. and Mary Alice Dickson Boyle. He received his bachelor’s degree from the University of North Carolina in 1943 before earning his medical degree from the Jefferson Medical College in Philadelphia in 1947. Between the years 1947 and 1951, Dr. Boyle held postdoctoral positions at institutions including Philadelphia General Hospital, Watts Hospital in Durham, North Carolina, and the University of Virginia in Charlottesville. From 1951 to 1955 he worked as a senior clinical investigator in the National Heart Institute’s Section on Metabolism at the National Institutes of Health. Prior to joining the MCSC, Dr. Boyle worked as an investigator for the American Heart Association.

Dr. Boyle first joined MCSC in 1956 as director of the Lipid Metabolism Laboratory and instructor in medicine. He was promoted to associate in medicine in 1958 and was later appointed assistant professor of research medicine in 1964. In 1966 Dr. Boyle became director of research for the Miami Heart Institute, a position he held until returning to MUSC in 1976. Upon rejoining MUSC, Dr. Boyle served as clinical professor of medicine in the Department of Medicine and directed a research program in aging.

His early research centered on the study of cardiovascular diseases and the prevention of heart attacks, strokes, congestive heart failure, and hypertension. Dr. Boyle was internationally recognized for developing a method of measuring cholesterol and breaking it down into different types. He was also known for his role in promoting the use of heparin as a form of therapy for certain types of cholesterol related diseases.

He was an expert in the fields of lipid metabolism and atherosclerosis before turning his attention to aging and the problems dealing with senility and memory loss. He maintained a strong interest in the sociological, cultural and psychological as well as the physiological and biochemical aspects of aging.

One of Dr. Boyle’s most significant accomplishments was the establishment of the CHS that began in 1960. He died in an automobile accident on July 9, 1978.

A self-contained mobile trailer unit, staffed by a registered nurse and a public health advisor, was used to contact and examine each potential subject at his/her place of residence.

Second Truck

The “New Moon Trailer” went into use on August 14, 1962. Lola Engler, RN, a project nurse during the initial two years of field activity, recalled that the trailer was a one-bed bunk trailer with a kitchen sink, electric heat, a water supply and a small toilet. The trailer was often cold in the winter because the electric heat was not very satisfactory. She also recalled that as the trailer was taken around the various neighborhoods some Charlestonians objected to the trailer’s being parked on their street.

An appointment card, along with an instruction sheet, was given to each participant at the time an appointment was made.

population data

Using population data from the 1950 census, researchers designed a sampling method to select participants for the Charleston Heart Study. Selected blocks were visited and sketches prepared showing the locations of all dwelling units in each block. The block was then subdivided into appropriate sampling units and one of those sampling units was selected at random for the sample proper. Sixty-four blocks were selected.

He graduated from The Citadel in 1937 and earned his medical degree from the Medical College of the State of South Carolina in 1941. After completing an internship at Brooke General Hospital in San Antonio, Texas, Dr. Sandifer joined the U.S. Army Medical Corps and fought in World War II. In 1949 he completed his residency in internal medicine at the Medical College of Virginia before completing a cardiology residency at Fitzsimons General Hospital, Aurora, Colorado in 1955.

During his twenty-four year career with the Army Medical Corps, Dr. Sandifer served as chief of the cardiology service and chief of the medicine department in various army hospitals and held fellowship positions with the American College of Physicians, the American College of Cardiology, and the American College of Preventive Medicine.

Dr. Sandifer retired from the Army in 1965 with the rank of colonel and was awarded the Legion of Merit. That same year Dr. Sandifer became the first full-time physician to The Citadel Corps of Cadets.
