Comparison between radial versus femoral percutaneous coronary intervention access in Indonesian hospitals, 2017-2018: A prospective observational study of a national registry.

Background: Coronary heart disease is a leading cause of death in Indonesia and percutaneous coronary intervention (PCI) is a routinely performed procedure. The aim of this study is to provide real-world insight on the demographics of coronary artery disease and comparison between radial compared to femoral PCI in Indonesia, which performed radial access whenever possible.

Methods: This is a prospective cohort study involving 5420 patients with coronary artery disease who underwent PCI at 9 participating centers in the period of January 2017-December 2018.

Impact of ischemic time on post-infarction left ventricular function in ST-elevation myocardial infarction treated with primary percutaneous coronary intervention.

Background: Myocardial necrosis is a time-dependent event. Nevertheless, clinical studies on association between ischemic time and left ventricle function showed inconsistent findings. Aim of current study is to evaluate the association between ischemic time and the post-infarction left ventricular function in ST-elevation myocardial infarction treated with primary PCI.

Coronary collaterals improve prognosis in patients with ischemic heart disease.

Background: The recruitment of coronary collateral vessels results from an endogenous adaptation to ischemic heart disease (IHD). Presence of collaterals may exert protection at the time of acute or chronic obstructive coronary disease. The protective role of collaterals in patients with extensive coronary artery disease however, has been disputed.
