Cardiorespiratory fitness, macronutrient intake, and the metabolic syndrome: the Aerobics Center Longitudinal Study.

Objective: This study examines the cross-sectional associations between cardiorespiratory fitness and the metabolic syndrome with adjustment for macronutrient intake from 3-day dietary records.

Design: Cross-sectional study.

Subjects/setting: Women and men who had a comprehensive medical examination, including a symptom-limited maximal treadmill exercise test, and completed 3-day dietary records at the Cooper Clinic, Dallas, TX.

Visceral fat is an independent predictor of all-cause mortality in men.

Objective: To examine the independent associations of abdominal fat (visceral and subcutaneous) and liver fat with all-cause mortality.

Research Methods And Procedures: Participants included 291 men [97 decedents and 194 controls; mean age, 56.4 +/- 12.

Coronary artery calcium score, risk factors, and incident coronary heart disease events.

Background: Whether the absence of coronary artery calcium, or conversely the presence of high volumes of coronary artery calcium, may alter assessment of coronary heart disease risk based on traditional risk factors is uncertain. We sought to identify a potential threshold of coronary artery calcium for clinical use and examine the predictive power of coronary artery calcium in individuals categorized using conventional coronary heart disease risk assessment.

Methods: The study included 10,746 men and women (36.

Coronary artery calcium, exercise tolerance, and CHD events in asymptomatic men.

Coronary artery calcium (CAC) scores >/=100 are predictive of CHD events in asymptomatic men. Exercise tolerance of >/=10METs predicts lower event rates in CHD patients; however, its relationship with events in individuals with subclinical atherosclerosis is less known. Participants were 710 asymptomatic men from the Aerobics Center Longitudinal Study whose exercise tolerance (ET) was quantified (<10 or >/=10METs) and whose CAC score was >/=100 as measured by electron beam tomography.

Coronary artery calcium score and coronary heart disease events in a large cohort of asymptomatic men and women.

Coronary artery calcium (CAC), a measure of subclinical coronary heart disease (CHD), may be useful in identifying asymptomatic persons at risk of CHD events. The current study included 10,746 adults who were 22-96 years of age, were free of known CHD, and had their CAC quantified by electron-beam tomography at baseline as part of a preventive medical examination at the Cooper Clinic (Dallas, Texas) during 1995-2000. During a mean follow-up of 3.
