Cardiovascular risk factors in the elderly.

Area of Science:

• Cardiology
• Epidemiology
• Geriatrics

Background:

• The Framingham Heart Study identified total plasma cholesterol as an early predictor of coronary heart disease (CHD).
• Established dose-response relationship: a 1% increase in total cholesterol correlates with a 2% increase in CHD incidence.
• This cholesterol-CHD link is now validated across age groups, including younger individuals and the elderly.

Purpose of the Study:

• To examine the relationship between total plasma cholesterol and CHD incidence in various age groups, with a focus on the elderly.
• To discuss the significance of multiple risk factors for CHD in older populations.
• To introduce new findings on left ventricular mass as a potential CHD risk factor in the elderly.

Main Methods:

• Analysis of data from the Framingham Heart Study.
• Examination of established CHD risk factors including lipids, uric acid, glucose, fibrinogen, and blood pressure.
• Inclusion of new data assessing left ventricular mass.

Main Results:

• The established relationship between total cholesterol and CHD incidence holds true for individuals aged 60 to 70 years.
• Multiple factors, including total cholesterol, lipoproteins, triglycerides, uric acid, glucose, fibrinogen, and hypertension, are associated with CHD risk.
• Increased left ventricular mass emerges as a significant potential risk factor for CHD, especially in the elderly.

Conclusions:

• Total plasma cholesterol remains a critical and consistent risk factor for coronary heart disease across the lifespan.
• A comprehensive assessment of cardiovascular risk in the elderly should include traditional factors and emerging markers like left ventricular mass.
• Effective management of cholesterol and other identified risk factors is crucial for preventing CHD, particularly in aging populations.
