Correlation Between the Severity of Coronary Artery Disease and Peripheral Arterial Stiffness in Patients With Premature Coronary Heart Disease

Premature coronary heart disease is defined as the first onset of male \< 55 years old, female \< 65 years old, confirmed by clinical examination. A number of studies have found that smokers have a significantly increased risk of acute myocardial infarction, and suggest that continued smoking is still an independent predictor of mace. These findings suggest that smoking is significantly associated with early-onset coronary heart disease. A number of studies have found that smoking can increase peripheral arterial stiffness. At present, there is no study on peripheral arterial stiffness in patients with early-onset myocardial infarction, so we suspect that peripheral arterial stiffness in patients with early-onset myocardial infarction is significantly increased
