In addition to the regular expert outpatient clinics and general outpatient clinics, the cardiology clinic also has various special disease and follow-up clinics: acute myocardial infarction follow-up clinic, heart failure and follow-up clinic, atrial fibrillation and follow-up clinic, pacemaker follow-up clinic, hypertension and Follow-up clinics, double heart clinics, cardiac rehabilitation clinics and other special clinics.

  In 2008, our hospital was authorized by the National Health Commission as a cardiovascular interventional diagnosis and treatment technology training base, including coronary heart disease intervention, arrhythmia intervention, and congenital heart disease intervention training base (congenital heart disease intervention training base is now under the management of radiology and surgery). Our institute is currently the only unit in Tianjin with all training bases. Following the establishment of the first batch of chest pain centers in Tianjin in 2014, our hospital has successively established heart failure centers, atrial fibrillation centers, hypertension centers, and cardiac rehabilitation centers in recent years, and has obtained corresponding certifications. It is currently the only one in Tianjin to obtain Units certified by the five major centers. Among them, the chest pain center, heart failure center, atrial fibrillation center, and cardiac rehabilitation center are all national demonstration bases. In 2018, the Department of Cardiology in our hospital was approved by the National Development and Reform Commission and the National Health Commission to be included in the National Cardiovascular Diagnosis and Treatment Capacity Improvement Project Reserve. At the same time, our hospital is also the affiliated unit of Tianjin Cardiovascular Disease Prevention and Treatment Office and the affiliated unit of Tianjin Cardiology Medical Quality Control Center. Our cardiology department has also been authorized by the American College of Cardiology to become the first batch of American College of Cardiology (ACC/AHA) training and education centers in China, and is the "American Heart Association Professional Demonstration Center."

  The distribution of subject personnel is reasonable. The old, middle-aged and young experts all work in the clinical frontline, and they have passed on their experience from generation to generation to train a large number of clinical experts. There are 152 physicians in the Department of Cardiology, including 36 chief physicians, 37 associate chief physicians, 36 doctors, 95 masters, 5 doctoral tutors, 18 master tutors, and 4 experts who enjoy special allowances from the State Council. There are 2 outstanding contribution experts in Tianjin, 5 first-level talents in Tianjin 131, 2 innovative talent teams in Tianjin "131", 1 talented person in Tianjin, and 1 young talent. The Backbone of the physicians studied abroad or studied in Europe and the United States, and studied and exchanged with Australia, Japan, the United States, Germany and other countries. The staff in our department have excellent quality, strong technical force and the ability to solve various difficult cardiovascular problems.

  In recent years, the Department of Cardiology completed more than 20,000 cardiac interventional examinations and treatment operations each year, with an annual average of about 10,000 coronary angiography, more than 8,000 cases of percutaneous coronary intervention, more than 1,200 cases of arrhythmia radiofrequency ablation, permanent pacemaker more than 700 cases of placement were performed, and other interventional operations such as congenital heart disease and large vessel valvular disease were undertaken by the Department of Cardiac Surgery. The number of operations is among the best in the country, and it is a household name in North China. It is the largest cardiac diagnosis and treatment center in Tianjin, highlighting the strong comprehensive clinical strength of our department.

  In terms of acute myocardial infarction treatment, our hospital treated more than 3,000 cases of acute myocardial infarction every year, and completed more than 1,000 cases of emergency PCI operations, ranking first in the country and in Tianjin. The CCU ward is the largest treatment center for difficult and critically ill patients with myocardial infarction in Tianjin. It is proficient in the use of IABP, ECMO, CRRT, Swan-Ganz and other critically ill patients. The success rate of CCU treatment is the highest in Tianjin, and the in-hospital mortality rate is 2.3%, which is significantly lower than the national level of 5.02%. In terms of interventional treatment of vein grafts after coronary artery bypass surgery, our cardiology department is the first in China to research and establish a precise diagnosis and treatment system for vein graft vascular diseases after coronary artery bypass surgery. SVG has been applied in lesions, and some of the results are internationally leading. Our hospital successfully carried out cryoablation surgery for atrial fibrillation, and was one of the first 5 cryo-ablation training centers in the country, with 4 global-certified cryoablation training instructors (a total of 26 nationally). In terms of heart failure treatment, continuous renal replacement and ultrafiltration treatment of refractory heart failure has always been one of the characteristics of our heart failure center, and it is at the leading level in the country. In terms of the construction of the chest pain center, our hospital, as the leader, has established a cardiovascular emergency treatment and cardiovascular disease prevention and control network covering the whole city, and the coverage rate is in a leading position in the country. In terms of interventional treatment of complex coronary lesions and the application of intra-coronary imaging technology, Intracoronary intravascular ultrasound (IVUS), intracoronary blood flow reserve (FFR), optical interference tomography (OCT) and other technologies have been carried out in our center for many years. The usage rate of intracavitary imaging was among the best in Tianjin. The application volume and application level of new interventional technologies such as drug balloons, cutting balloons, rotational atherectomy, laser ablation and biodegradable stent implantation are also at the leading level in the city. Conventional arrhythmia surgery techniques, left atrial appendage closure, His bundle pacing, leadless pacemaker implantation, and subcutaneous ICD surgery have consistently ranked first in the city. Almost all new technologies were first developed by our hospital in the city, ranking first in the city in terms of the number and quality of operations. CRT treatment of heart failure is at the leading level in Tianjin, and the success rate of surgical placement is as high as 95%. At the same time, our hospital has matured left ventricular epicardial pacing, that is, the implementation of epicardial pacing therapy for patients who have failed interventional placement. After the operation, there is a special pacemaker follow-up clinic to optimize pacing parameters, and the effective rate of CRT exceeds 70%. We vigorously developed the clinical application of double-heart medicine. In August 2012, we established the first "double-heart clinic" in Tianjin in our hospital. Our hospital's experience in double-heart medicine has been widely used in the city and even across the country, and it has effectively promoted the improvement of the early recognition and treatment of double-heart disease in surrounding hospitals and regions. Our hospital provided comprehensive cardiac rehabilitation guidance for cardiovascular patients through mature cardiac rehabilitation technology. The Cardiac Rehabilitation Department conducts individualized tailor-made sports training, evaluation-level multidisciplinary comprehensive management for patients, and is the first in the city to pass the review of the China Rehabilitation Center. In 2021, our hospital will take the lead in establishing the Tianjin Heart Rehabilitation Center Alliance and serve as the chairman unit. The application of remote technology such as the remote Holter monitoring system can diagnose and warn cardiovascular events such as myocardial infarction and arrhythmia through real-time monitoring of the remote Holter monitoring system. At the same time, the Internet is used to facilitate the construction of the cardiovascular specialist medical consortium and the chest pain center. We have established a comprehensive ward, focusing on the development of hypertension prevention and treatment, cardiac rehabilitation, and clinical drug testing bases.
