Quality of Care and Long-term Survival After ST-elevation Myocardial Infarction in Adults with Cancer. European Heart Journal - Quality of Care and Clinical Outcomes, https://doi.org/10.1093/ehjqcco/qcaf004

Background
While current evidence suggests that the clinical outcomes of ST-elevation myocardial infarction (STEMI) are worse among patients with cancer, it is unknown what role the quality of care received during admission plays. We aimed to evalua... Read More about Quality of Care and Long-term Survival After ST-elevation Myocardial Infarction in Adults with Cancer.
