Timeliness of reperfusion in ST-segment elevation myocardial infarction and outcomes in Kerala, India: results of the TRUST outcomes registry.
Purpose: Transatlantic guidelines endorse quality metrics for timely reperfusion in patients with ST-elevation myocardial infarction (STEMI). Compliance in low- and middle-income countries (LMICs) is largely unknown.
Study design: We prospectively evaluated 2928 STEMI patients in Kerala, India, across 16 PCI-capable hospitals who received reperfusion with either primary percutaneous coronary intervention (PPCI) or fibrinolysis. Primary endpoint was a major adverse cardiovascular event (MACE) composite of death, non-fatal myocardial infarction, stroke or readmission for heart failure at 1-year.
Results: Among reperfused STEMI patients, 320 (10.9%) received timely reperfusion with either PPCI or fibrinolysis, 1985 (67.8%) received delayed PPCI, and 623 (21.3%) received delayed fibrinolysis. Timely reperfusion had lower unadjusted MACE rates than delayed PCI or fibrinolysis (timely reperfusion: 11.9%, delayed PPCI: 13.6%, delayed fibrinolysis: 23.9%, P < 0.001). Mortality was lowest in the timely reperfusion group (timely reperfusion: 6.3%, delayed PPCI: 7.8%, delayed fibrinolysis 18.8%, P < 0.001). After multivariate analysis, delayed fibrinolysis had a higher MACE rate (HR 1.52 95% CI 1.04-2.21) and mortality (HR 1.97, 95% CI 1.18-3.25) compared to timely reperfusion. Total ischemic time > 3 h and delayed first medical contact-to-needle time predicted MACE at 1 year.
Conclusions: Among STEMI patients in Kerala, India, only one in 10 eligible patients received timely reperfusion. Longer total ischemic times and delayed fibrinolysis were associated with 1-year MACE. Improving timely reperfusion is critical to enhancing STEMI outcomes in LMICs. What is already known on this topic Given the established link between delay to reperfusion and worse major adverse cardiac events (MACE), global efforts have concentrated on minimizing different components of the total ischemic time to improve ST-elevation myocardial infarction (STEMI) outcomes. Compliance in low- and middle-income countries (LMICs) is largely unknown. What this study adds In this cohort of STEMI patients in Kerala, India, total ischemic time and first medical contact-to-needle time correlated with long-term MACE rates, whereas other timeliness indicators did not. How this study might affect research, practice or policy Our study highlights the significant barriers to accessing STEMI care that are prevalent in LMICs despite incremental growth in the number of PCI-capable hospitals. The pre-hospital phase within total ischemic time is the most important quality improvement metric of STEMI care in LMICs, especially for patients chosen for fibrinolysis.
期刊介绍：
Postgraduate Medical Journal is a peer reviewed journal published on behalf of the Fellowship of Postgraduate Medicine. The journal aims to support junior doctors and their teachers and contribute to the continuing professional development of all doctors by publishing papers on a wide range of topics relevant to the practicing clinician and teacher. Papers published in PMJ include those that focus on core competencies; that describe current practice and new developments in all branches of medicine; that describe relevance and impact of translational research on clinical practice; that provide background relevant to examinations; and papers on medical education and medical education research. PMJ supports CPD by providing the opportunity for doctors to publish many types of articles including original clinical research; reviews; quality improvement reports; editorials, and correspondence on clinical matters.
