Primary Risk Factors for Cardiovascular Disease

Pathophysiology and Risk Factors

• Obesity creates a synergistic effect with hypertension, exceeding the sum of individual risk factors, with 35.7% of obese individuals having hypertension 3, 1
• Hypertension accelerates atherosclerosis and vascular remodeling, directly impairing peripheral circulation and exercise tolerance 1, 4
• Among adults with hypertension, 49.5% are obese, resulting in high absolute risks for cardiovascular events, with 41.7% having a 10-year CHD risk >20% 5, 3
• The American Heart Association identifies hypertension as the leading modifiable CVD risk factor, second only to current cigarette smoking as a preventable cause of death 5, 3

Clinical Presentation and Diagnosis

• Exercise intolerance requiring medical evaluation is never "normal for age" and represents pathology requiring intervention 2
• The American College of Cardiology explicitly states that difficulty with activities of daily living represents disease, not aging 2

Management and Treatment

• Blood pressure control reduces MI, stroke, heart failure, and death risk in patients with peripheral arterial disease, with a target <140/90 mmHg 6, 1
• Weight loss combined with structured exercise programs increases pain-free and maximum walking distances despite initial discomfort 1, 2
