在“争创国内一流，国际知名的学院型医院”方针的指导下，心内科始终重视科研对学科发展的助推作用。心血管病研究室创立于1986年, 1988 年在国内首次发现并分离、提取了人类白细胞血管紧张素Ⅱ物质，建立了血浆肾素活性的检测方法;率先在国内提出国人老龄化进程中心功能及心脏结构的衍变特点、心包具有合成、贮存、分泌心钠素的功能、单纯性收缩期高血压主要表现为舒张功能损害、舒张期高血压主要表现为收缩功能损害、生理性舒张功能减退与舒张性心力衰竭的鉴别诊断及临床意义等观点。在高血压病个体化治疗、心脏结构、血流及功能与循环心钠素及肾素-血管紧张素系统关系、急性心肌梗死溶栓纤溶系统监测等方面作了许多有意义的工作。心内科同时承担了多项科研基金项目，并取得了丰厚的成果。先后承担国家攻关、国家自然科学基金、首都医学发展基金重大课题、市科委、市教委、市卫生局、首医大基临课题等二十余项，获得市部级以上科技进步奖十余项。
The Department of Cardiology of Xuanwu Hospital has gone through a 60-years of development. From the beginning of its establishment, under the leadership of Professor Wang Jiarui, the famous expert on cardiovascular disease in China, the Department of Cardiology was founded and gradually developed into an integrated well-known cardiovascular discipline, with professional and advanced technology, standardized diagnosis and treatment, distinctive characteristics, along with its medical teaching and research in China. Cardiology includes intensive care, coronary intervention, cardiac pacing and electrophysiology, echocardiography, non-invasive ECG examination, cardiac rehabilitation and other professional groups. The annual number of out-patient, inpatient , operation and interventional treatment are all ranked at the top list of capital Grade 3A general hospital.
To response to aging and changes of disease spectrum and many complications diseases, the coronary heart disease intensive care unit, which previously known as CCU, is developing to CICU. CICU has combined ICU technology, concept and diagnosis and treatment mode, through multiple management including infection control, nutritional support, auxiliary cycle (IABP, ECMO), invasive and noninvasive respiratory support, bedside hemofiltration, bedside ultrasound hemodynamic evaluation, etc. CICU has significantly improved the treatment level of critically ill patients, and becomes an important part of the national clinical specialty in intensive care and an important supporter for the development of cardiovascular specialty.
The interventional therapy of coronary heart disease has been carried out for more than 20 years in Department of Cardiology. Tens of thousands of cases of coronary artery disease have been diagnosed and treated so far, and achieved very good results. The interventional therapy technology of rotablator, laser, intravascular ultrasound ( IVUS ), optical coherence tomography (OCT) and Fractional flow reserve (FFR) have been widely used in complex lesions coronary artery such as CTO. Department of Cardiology has become the national training base of coronary intervention technology.
The cardiac pacing and electrophysiological specialty group has rich experience in treatment of bradyarrhythmia with pacemakers, and can well complete the installation of advanced instruments such as dual-chamber and three-chamber pacemakers and implantable cardioverter-defibrillator (ICD). Good curative effect has obtained. Particularly, great progress has been made in radiofrequency ablation in the treatment of tachyarrhythmias in recent ten years. Advanced three-dimensional electrophysiologic radiofrequency ablation apparatus was used to complete the treatment of frequent ventricular premature, ventricular tachycardia, supraventricular tachycardia, atrial flutter, atrial fibrillation and other arrhythmia diseases. The number of cases and effect were in the forefront of Beijing. Department of Cardiology has become the national arrhythmia intervention professional training base.
Department of Cardiology has advanced cardiac ultrasound equipment and experienced experts. In addition to the general cardiac ultrasound examination, we also complete lots of bedside echocardiography, transesophageal echocardiography, right ventricular contrast echocardiography, preoperative and postoperative vascular assessment, operation monitoring of cardiac and neurosurgical surgery .
As the first clinical hospital of the Capital Medical University, the Department of Cardiology undertakes the teaching tasks of physical diagnostics and cardiovascular clinical medicine, and is the earliest standardized training base for residents, has lots of experienced teachers. Department of Cardiology is also the first to set up master's degree and doctoral training point discipline of the Capital Medical University, and has trained students who obtained master's degree, doctoral and postdoctoral degree nearly 100.
With the guideline of "striving to first-class and famous collegiate hospital internationally ", Department of Cardiology always attached importance to the role of scientific research in promoting the development of disciplines. The cardiovascular laboratory was established in 1986 . In 1988, angiotensin II in human leukocytes was been isolated and extracted for the first time in China, and established a method for plasma renin activity. It was first proposed that the central function of aging process and the evolution of cardiac structure in China, the pericardial function of synthesizing, storing and secreting atrial natriuretic peptide, and the isolated systolic hypertension mainly manifested diastolic function damage. The diastolic hypertension manifested systolic dysfunction, the difference of physiological diastolic dysfunction and diastolic heart failure. individualized treatment of hypertension, the relationship between cardiac structure, blood flow and function and circulating atrial natriuretic peptide (ANP) and renin-angiotensin system, and the monitoring of thrombolytic and fibrinolytic system in acute myocardial infarction (AMI). At the same time, Department of Cardiology has successively undertaken more than 20 national key research projects, the national natural science foundation, the capital medical development fund, the municipal science and technology commission, the municipal education commission, the municipal health bureau, and the basic and temporary projects of the first medical university, and we have won more than ten scientific and technological progress awards at or above the ministerial level.
Now, Xuanwu Hospital is entering into a new historical period of its development, the Department of Cardiology will take the advantages of the National Geriatrics Center and neuroscience, expanding and innovating in the fields of cardiovascular diseases, and diagnosis and treatment in cardio-cerebral co-diseases interdisciplinary in the elderly. the Department of Cardiology will strengthen the new discipline development and innovated diagnosis and treatment pattern , to benefit our patients.
