A Cohort Study of Chronic Cardiovascular Diseases

Study Overview
=================
Brief Summary
-----------------
This prospective cohort study aims to establish cohorts of patients with chronic cardiovascular disease, including refractory and secondary hypertension, coronary heart disease, atrial fibrillation, ventricular arrhythmias, structural heart disease, pulmonary hypertension, heart failure and rare diseases of the cardiovascular system, and patients with implantations of cardiac pacemaker, in order to dynamically describe the population characteristics, diagnosis and treatment status and long-term prognosis and analyze the factors affecting the choice of treatment plan, long-term management quality and clinical prognosis of these patients.
