Baseline Characteristics of Patients

Group
CharacteristicTotal (N=255)Intervention (n=45)Control (n=43)P ValueSpecialist (n=167)
BMI = body mass index; BP = blood pressure; CABG = coronary artery bypass grafting; CCS = Canadian Cardiovascular Society classification system of current angina pectoris symptoms; CHD = coronary heart disease; HDL=high-density lipoprotein; LDL=low-density lipoprotein; MI=myocardial infarction; PCI=percutaneous coronary intervention.
Notes: Patient group reflects the group to which the patient’s treating physician was assigned. Specialist denotes the group of patients treated by a specialist in cardiology or internal medicine.
a Triglyceride values in millimoles per liter were converted to milligrams per deciliter by multiplying by 88.57. Other cholesterol values were converted to milligrams per deciliter by multiplying by 38.67.
