The lead author of the study, Dr Thomas Sudhop, notes that in patients with the inherited disease of phytosterolemia, elevated concentrations of plant sterols (eg, campesterol and sitosterol) (think Benecol and Flora proactive) have been implicated as a risk factor for premature atherosclerosis.

This study examined the role of plant sterols in patients (with plant sterol levels in the normal range) admitted for elective artery coronary bypass graft surgery. The study included 53 patients of which 26 reported a family history in their first-degree relatives for coronary heart disease.

The study found:
(a) Patients with a positive family history for coronary heart disease had a significant 31% higher plasma levels of campesterol compared to patients without a family history of coronary heart disease.
(b) Patients with a positive family history for coronary heart disease had a significant 29% higher plasma levels of sitosterol compared to patients without a family history of coronary heart disease.
(c) Patients with a positive family history for coronary heart disease had a significantly higher ratios of sitosterol to cholesterol and campesterol to cholesterol compared to patients without a family history of coronary heart disease.

Dr Sudhop concluded: "These findings support the hypothesis that plant sterols might be an additional risk factor for coronary heart disease".
