A 47-patient validation study of Cardio-HART (CHART), a point-of-care cardiac assessment tool, demonstrated clinically acceptable agreement with echocardiography for measuring left ventricular ejection fraction, showing a mean bias of just +1.92% and strong diagnostic performance for heart failure with reduced ejection fraction (area under curve 0.89). The study included predominantly ischemic heart failure patients with a mean age of 65.6 years. Beyond technical validation, this research unexpectedly revealed a critical healthcare delivery problem: significant workflow gaps between the theoretical availability of echocardiography and patients actually receiving timely cardiac assessment in routine clinical practice. This finding challenges assumptions about cardiac care accessibility and suggests that diagnostic delays may be more common than recognized, potentially affecting patient outcomes through delayed heart failure diagnosis and treatment initiation. The discovery highlights how point-of-care tools might serve dual purposes - not only providing diagnostic capability but also exposing hidden inefficiencies in healthcare workflows. However, as a preprint awaiting peer review, these findings require validation in larger cohorts and broader clinical settings before informing policy changes. The study represents an incremental but practically important advance in understanding real-world cardiac care delivery challenges.
