Brief summary
The investigators want to explore the relationship between different configurations of hypertension and the incidence of cardiovascular events by the guidelines reference range and EMINCA recommended reference range. Then the investigators want to enroll twenty research centers and 2200 hypertensions were planned to be collected and followed up in the 12th, 24th, 36th and 48th months after being enrolled in this study. Physical examination, ECG examination, laboratory examination, echocardiography and carotid ultrasound should be taken when baseline and follow-up. Echocardiographic measurement parameters were analyzed and the relationship between the echocardiographic measurement parameters and cardiovascular events and prognosis of hypertension.
Detailed description
Different configurations of hypertension are important risk factor for the morbidity and mortality of cardiovascular and cerebrovascular diseases in China. Studies have shown that left ventricular hypertrophy (LVH) and left atrial enlargement caused by hypertension are independent risk factors for cardiovascular events. The LVM and LAV derived from the normal value data of Chinese healthy adults have been reported to be different from the recommended reference values in guidelines, and the distribution characteristics of hypertension remodeling are also different. However, the characteristics and outcomes of cardiac remodeling in Chinese hypertensive population and whether this difference in configuration has an impact on the treatment, prognosis and cardiovascular events of hypertensive population are still needed to be explored. This study was to observe the relationship between blood pressure and cardiovascular remodeling evaluated by different standards in hypertensive population, and compare the relationship between different cardiac configurations and cardiovascular events in Chinese hypertensive population. Twenty research centers and 2200 hypertensions were planned to be collected and followed up in the 12th, 24th, 36th and 48th months after being enrolled in this study. Physical examination, ECG examination, laboratory examination, echocardiography and carotid ultrasound should be taken when baseline and follow-up. Echocardiographic measurement parameters including M-mode and two-dimensional ultrasonic parameters; doppler ultrasound parameters; relevant parameters of two-dimensional speckle tracking, myocardial work parameters; the left ventricular remodeling parameters (LVM and RWT); cardiac morphological changes; three-dimensional ultrasound parameters were analyzed and the relationship between the echocardiographic measurement parameters and cardiovascular events and prognosis of hypertension.
