SURVIVORSHIP OF CORONARY ARTERY BYPASS GRAFTING PATIENTS UNDER CARDIOPULMONARY BYPASS IN GOVERNMENT HOSPITALS, THAILAND
Main Article Content
Abstract
The study design was a retrospective cohort. The objectives were to estimate the survivorship functions of a patient who underwent isolated coronary artery bypass grafting (CABG) surgery in government hospitals of Thailand and identify factors affecting survival time for early mortality (≤ 30 days mortality) after the surgery. Population were the CABG patients in government hospitals by using data extracted from the database registry of the Society of Thoracic Surgeons of Thailand during January 1, 2006 to December 31, 2006 and followed up the vital status until December 31, 2011.
A total of 1,729 patients were identified. The follow-up time range from 0 to 30 days (median = 29.4) was defined as early mortality and range from 0 to 73 months (median = 64.9) was defined as all study period. All mortality was 18.2% (3% in early mortality). At 30 days, 12-month, and 72-month survival rates for CABG patients were 97%, 94%, and 82%, respectively. The 15th percentiles of event-free survival was 47 months. According to the Cox proportional hazard regression revealed that NYHA class II (Hazard ratio (HR) 0.47), fair and poor left ventricular ejection fraction (HR 2.52 and 2.77, respectively), cardiopulmonary bypass time (CPB) (HR 1.007), pre-operative and post-operative intra aortic balloon pump support (HR 2.91 and 13.22, respectively), and new heart failure after surgery (HR 10.49) were significant factors of early mortality.
The significant risk factors affecting survival time for early mortality were cardiac-related conditions. The physician and health care team should be aware and have an excellent plan for risk assessment and patient counseling in pre-operative period, a caring treatment in intra-operative and post-operative period to reduce the mortality rate.
