ABSTRACT
In South-East Asian populations and particularly in Indonesia, access to coronary angiography (CAG) is limited. We aimed to assess the adherence for undergoing CAG for indicated patients, according to the guideline recommendations. We then examined whether this adherence would have an impact on patients' short- and medium-term mortality and morbidity. We consecutively enrolled 474 patients with acute and stable coronary artery disease who had indication for CAG at Makassar Cardiac Center, Indonesia from February 2013 to December 2014. We found that adherence to CAG recommendation in poor South-East Asian setting is low. Of 474 recommended patients, only 273 (57.6%) underwent the procedure. Factors for not undergoing CAG were: older age, female gender, low educational and socio-economic status, and insurance type. While reasons for patients refusing CAG and subsequent intervention included fear, symptoms reduction, and lack of trust concerning the procedure benefit. During follow-up (median 19 (IQR 6-39.3) months), 155 (32.7%) patients died, and 259 (54.6%) experienced at least one adverse event. Adherence to CAG recommendation was associated with a significantly lower short- and medium-term mortality, independent of revascularization and other potential confounders. In sub-group analysis, adhered patients "with revascularization" had significantly better outcomes compared to the "non-revascularization" and "not adhere" groups.
