Trends of coronary revascularization procedures in Gaza
Background: we investigated the results of diagnostic coronary angiography and trends in rates of myocardial revascularization procedure included Percutaneous Coronary Intervention (PCI) and Coronary Artery Bypass Grafting (CABG) procedures in Gaza between 2015 and 2018. Methods: A descriptive retrospective study based on the analysis of all diagnostic Coronary Angiographies (CAG) based on the Ministry of Health hospitals in Gaza City Report and the Center of Bureau of Statistics, to evaluate the annual rate of PCI and CABG volume have been done since January 2015until January 2019. Results: A total of 4887 diagnostic coronary angiography procedures were performed. The mean age of patients was 58.0±10.2 years. A 3245 of cases were male (66.4%). A total of 5225 revascularization procedures (PCI: 4286,CABG: 939) were performed during the study period. From 2014 to 2018 the PCI volume increased by 94 % (80/100 000 to 155/100 000)(P < 0.0001), CABG volume decreased by 47 % (30/100 000 to 17 /100 000) (P <0.0001), PCI/CABG ratio increased from 2.7 to 9.1(P<0.0001).The indications for diagnostic coronary angiography were stable angina (57% of cases), non-ST-elevation acute coronary syndrome (NSE-ACS) in 24.0%, ST-elevation myocardial infarction (STEMI) in 19.0%, the diagnostic coronary angiography results showed significant lesions in 64.5% of patients. About 19.2% of total cases have three vessel disease, 21% have two vessel disease and 24.4% of them have one vessel disease. The segments most involved were Left Anterior Descending Artery (LAD) which was involved in 47.2% of cases. Discussion: We observed dramatic increases in the total coronary revascularization procedures with a marked decrease in CABG and increase in PCI procedures in Gaza.
