Serum lipid response to a fat-modified, oatmeal-enhanced diet.

The purpose of this study was to confirm and extend previous findings that serum cholesterol response to a fat-modified diet is enhanced by oat fiber. Participants (n = 236) were recruited from the Continental Illinois National Bank in Chicago. Data including weight, serum lipid level, lipoproteins, and 3-day food records were collected at baseline and every 4 weeks for 12 weeks.

Do hypertensive patients have a different diurnal pattern of electrolyte excretion?

Studies generally indicate that excretion of sodium, potassium, and water is greater during the day than during the night. To determine whether hypertensive patients exhibit this same pattern of excretion, diurnal variations in excretion of sodium, potassium, creatinine, and water were examined in 107 hypertensive men and women from a clinical trial on control of hypertension by nonpharmacological means--the Hypertension Control Program. Each participant provided two carefully timed 24-hour urine collections divided into daytime and overnight specimens.

Cardiovascular responses to exercise of participants in a trial on the primary prevention of hypertension.

The Chicago study on the Primary Prevention of Hypertension (PPH) is a long-term, randomized controlled trial to test the ability of nutritional-hygienic non-pharmacological methods to prevent high blood pressure in hypertension-prone persons aged 30-44 years at entry. In order to assess the effects of this programme on cardiovascular responses to exercise, graded submaximal treadmill exercise tests were done serially at baseline and during the trial. Eighty-five participants (48 intervention, 37 control) successfully finished baseline and 2- or 3-year follow-up tests.

Serum lipid response to oat product intake with a fat-modified diet.

Healthy adult volunteers (no. = 208), men and women aged 30 to 65 years, participated in a 12-week study on dietary fat modification plus oat product ingestion (60 gm/day) to test whether moderate daily intake of oat bran and oatmeal enhanced serum lipid response. During weeks 0 to 6, all participants followed the American Heart Association fat-modified eating style.

Characteristics and prognosis of incomplete right bundle branch block: an epidemiologic study.

A cohort of 1,960 white men aged 40 to 56 years without initial apparent heart disease and with 11 years of annual rest electrocardiograms and 20 year mortality data was followed in the Chicago Western Electric Company Study. Incomplete right bundle branch block was found in 134 men (6.8%) at entry.
