Influence of elderly patients' coronary artery lesion severity on cardiac remodeling and left ventricular function.

Objective: To analyze the correlation between coronary artery lesion and cardiac function change among elderly patients with coronary heart disease (CHD). Methods: A total of 171 elderly patients with CHD hospitalized from 2009 to 2016 were selected. Their ultrasonic cardiographic and coronary angiographic data were collected, and the correlation between coronary artery lesion and left ventricular remodeling, systolic and diastolic function was analyzed. Results: Coronary artery lesion among elderly patients with CHD was closely related with left ventricular remodeling and systolic function change, but not significantly correlated with diastolic function change. Conclusion: Coronary artery lesion severity of elderly patients with CHD was an important reason for left ventricular remodeling and cardiac systolic function change. Early intervention of coronary artery disease is of great significance to protect the heart function. [ABSTRACT FROM AUTHOR]
