Impact of Physician-Coordinated Intensive Follow-Up on Long-Term Medical Costs in Patients with Unstable Angina Undergoing Percutaneous Coronary Intervention.

Background: To investigate the impact of professional physician-coordinated intensive follow-up on long-term expenditures after percutaneous coronary intervention (PCI) in unstable angina (UA) patients.

Methods: In this study, there were 669 UA patients who underwent successful PCI and followed up for 3 years, then divided into the intensive follow-up group (N = 337), and the usual follow-up group (N = 332). Patients were provided with detailed discharge information and individualized follow-up schedules.

Association between left ventricular end-diastolic pressure and coronary artery disease as well as its extent and severity.

Patients with myocardial ischemia exhibit increased left ventricular end-diastolic pressure (LVEDP). The study was to evaluate the relationship between LVEDP measured by left cardiac catheterization and coronary artery disease (CAD) as well as its extent and severity evaluated by coronary angiography (CAG). 912 patients who underwent CAG and left cardiac catheterization were enrolled.
