AI Article Synopsis
- The study examined the impact of hospital procedural volume on patient outcomes for those undergoing percutaneous intervention (PCI) for heart attacks.
- It analyzed data from 9360 patients in the Dallas area over six years and categorized hospitals into low, intermediate, and high volume based on their PCI activity.
- Results showed that high-volume hospitals had significantly better performance, with shorter treatment times and lower mortality rates, confirming the positive volume-outcome relationship in interventional cardiovascular care.
Article Abstract
Background: Management theories of learning and experience curve effects state that greater levels of scale produce learnings and improved performance. In cardiovascular care, guidelines suggest that high-volume facilities produce better patient outcomes; yet, there are contradictory findings from the few studies conducted. Our goals were to assess the volume-outcome relationship for interventional cardiovascular care.
Methods: We examined 9360 patients with ST-segment elevation myocardial infarction who underwent percutaneous intervention (PCI). We analyzed 6 years of data (2010-2015) using systematic extracts provided by 33 PCI-capable hospitals in the Dallas Texas region from the National Cardiovascular Data Registry. We stratified hospitals into 3 procedural volume categories (low, intermediate, and high) to identify changes in 2 key outcome metrics (ie, door-to-balloon times and mortality). Multivariate analyses and tests of differences were utilized.
Results: Door-to-balloon performance outcome was significantly different between volume categories, with the highest-volume hospitals performing significantly better than intermediate- and low-volume hospitals (47, 60, and 75 minutes, respectively; P < .001). Mortality followed a similar pattern, with a 3.3% unadjusted absolute lower mortality rate for the high-volume hospitals. Multivariate regressions confirm that volume is statistically significant in both mortality and treatment times.
Conclusions: Higher-volume PCI hospitals have 37% shorter treatment times and 53% lower mortality rates than smaller facilities. This study provides evidence of a positive volume-outcome relationship in interventional cardiovascular care.

Background: The health benefits of physical activity, including walking, are well-established, but the relationship between daily step count and mortality in hypertensive populations remains underexplored. This study investigates the association between daily step count and both all-cause and cardiovascular mortality in hypertensive American adults.
Methods: We used data from the National Health and Nutrition Examination Survey 2005-2006, including 1,629 hypertensive participants with accelerometer-measured step counts.

Objectives: To investigate through a meta-analysis of comparative studies the impact of donor type (brain death DBD vs circulatory death DCD) on the short- and long-term outcomes of lung transplantation(LTx).
Methods: Literature search (terms "lung transplantation" AND "donation after circulatory death") was performed up to July 2022 and studies comparing outcomes of LTx from DCD versus DBD were selected. Primary endpoints were early and long-term mortality.

Background & Aims: A healthy diet improves cardiovascular disease (CVD) risk factors. However, dietary counseling is not yet widely implemented in health care for patients with CVD. We assessed how dietary counseling by a dietitian, focused on improving diet quality, influenced the cardiovascular risk profile of patients with CVD.

Background: Although there have been reports that green tea intake has thromboprophylactic effect, it was still unknown whether it had adjuvant effect on the basis of conventional anticoagulation for patients diagnosed with venous thromboembolism (VTE).
Methods: VTE patients were retrospectively classified into green tea group and no green tea group in a 1:1 ratio using propensity score matching, based on whether they drank green tea during the 3 months' period after VTE diagnosis. Primary outcomes were VTE recurrence at 3 months after VTE diagnosis and VTE-related death during 3 months after VTE diagnosis.
