A Cohort Study of Chronic Cardiovascular Diseases

A Cohort Study of Chronic Cardiovascular Diseases in the Department of Cardiology, Peking University First Hospital

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.

This study includes 9 disease-specific cohorts. The specific inclusion and exclusion criteria are as following:

1. Refractory and secondary hypertension

   Inclusion Criteria:

   • Patients diagnosed as refractory hypertension and/or secondary hypertension
   • Patients willing to accept long-term follow-up and regular return visits

   Exclusion Criteria:

   • Severe diseases of other systems may affecting the life span of patients

2. Coronary heart disease

   Inclusion Criteria:

   • Patients undergoing coronary angiography and interventional therapy in the cath lab
   • Patients undergoing coronary angiography and functional assessment in the cath lab
   • Patients diagnosed as acute myocardial infarction

   Exclusion Criteria:

   • Severe diseases of other systems may affecting the life span of patients
   • Regular return visits not available

3. Atrial fibrillation

   Inclusion Criteria:

   • PAtrial fibrillation diagnosed by electrocardiogram or holter (duration >30 seconds)
   • Patients willing to accept long-term follow-up and regular return visits

   Exclusion Criteria:

   • Severe diseases of other systems may affecting the life span of patients
   • New-onset atrial fibrillation during the perioperative period of major surgery

4. Ventricular arrhythmias

   Inclusion Criteria:

   • Patients diagnosed as ventricular tachycardia, ventricular premature beat
   • Patients willing to accept long-term follow-up and regular return visits

   Exclusion Criteria:

   • Severe diseases of other systems may affecting the life span of patients
   • A transient cause of ventricular arrhythmia was determined by the doctor, and long-term follow-up was not required

5. Cardiac pacemaker implantation

   Inclusion Criteria:

   • Patients with permanent pacemaker implantations due to various causes (including bradycardia pacing, implantable cardioverter defibrillator, cardiac resynchronization therapy, leadless cardiac pacemaker, etc.)
   • Patients willing to accept long-term follow-up and regular return visits

   Exclusion Criteria:

   • Severe diseases of other systems may affecting the life span of patients

6. Structural heart disease

   Inclusion Criteria:

   • Patients diagnosed as structural heart disease, including congenital heart disease and severe valvular disease (moderate and above valvular stenosis or incomplete closure)
   • Patients willing to accept long-term follow-up and regular return visits

   Exclusion Criteria:

   • Severe diseases of other systems may affecting the life span of patients

7. Pulmonary hypertension

   Inclusion Criteria:

   • Patients diagnosed as pulmonary hypertension
   • Patients willing to accept long-term follow-up and regular return visits

   Exclusion Criteria:

   • Severe diseases of other systems may affecting the life span of patients

8. Heart failure

   Inclusion Criteria:

   • Patients diagnosed as heart failure
   • Patients willing to accept long-term follow-up and regular return visits

   Exclusion Criteria:

   • Severe diseases of other systems may affecting the life span of patients

9. Rare diseases of the cardiovascular system

Inclusion Criteria:

• Patients diagnosed as rare diseases in the catalog published by National Health Commission of the People's Republic of China
• Patients willing to accept long-term follow-up and regular return visits

Exclusion Criteria:

• Severe diseases of other systems may affecting the life span of patients
