Brief Summary:
Hypertension is a serious threat to human health and a major global economic burden.Chronic hypertension can cause left ventricular remodeling and loss of function, eventually leading to heart failure.Exploring the early changes and mechanisms of left ventricular cardiac function caused by hypertension, and to identify individuals who may develop into serious heart injury, may play a positive role in the early prevention and control of heart failure caused by hypertension.Therefore, this study intend to use two-dimensional speckle tracking technology, a non-invasive method to measure left ventricular pressure-strain loop to quantitatively reflect cardiac work index , to study different hypertension patients with normal left ventricular ejection fraction the change of the global and local cardiac work, and the influence of aterosclerosis in thes patients to myocardial work, and explore their relationship with ventricular remodeling and abnormal diastolic function.To improve the understanding of the pathophysiology of hypertension, hypertensive heart disease and heart failure, and to provide scientific support for the early prevention and control of such diseases.
Detailed Description:
Hypertension is a serious threat to human health and a major global economic burden.Chronic hypertension can cause left ventricular remodeling and loss of function, eventually leading to heart failure. Ventricular remodeling in hypertensive patients is an adaptive and decompensating response to persistent elevated blood pressure and increased myocardial work load. Exploring the early changes and mechanisms of left ventricular cardiac function caused by hypertension, and to identify individuals who may develop into serious heart injury, may play a positive role in the early prevention and control of heart failure caused by hypertension.Therefore, this study intend to use two-dimensional speckle tracking technology, a non-invasive method to measure left ventricular pressure-strain loop to quantitatively reflect cardiac work index , to study different hypertension patients with normal left ventricular ejection fraction (including hypertension without heart damage performance with different degree of high blood pressure, hypertension with diastolic dysfunction , hypertension with left ventricular hypertrophy ) the change of the global and local cardiac work, and the influence of aterosclerosis in thes patients to myocardial work, and explore their relationship with ventricular remodeling and abnormal diastolic function.To improve the understanding of the pathophysiology of hypertension, hypertensive heart disease and heart failure, and to provide scientific support for the early prevention and control of such diseases.
