Examining Disparities and Excess Cardiovascular Mortality Before and During the COVID-19 Pandemic.

OBJECTIVE: To investigate the patterns and demographic features of cardiovascular disease (CVD) death and subtypes myocardial infarction (MI), stroke, and heart failure in the pre-COVID-19 era (2018-2019) vs during the COVID-19 pandemic (2020-2021) in the United States. METHODS: In this cross-sectional study, we used the US Multiple Cause of Death files for 2018 to 2021 to examine the trend of excess cause-specific deaths using International Classification of Diseases, Tenth Revision codes for CVD (I00 to I99), MI (I21 and I22), stroke (I60 to I69), and heart failure (I42 and I50). Our primary outcome was excess mortality from CVD and its 3 subtypes (MI, stroke, and heart failure) between prepandemic (2018-2019) and pandemic (2020-2021) years. We performed a subgroup analysis on race and month-to-month and year-to-year variation using χ2 analysis to test statistical significance. RESULTS: Overall, 3,598,352 CVD deaths were analyzed during the study period. There was a 6.7% excess CVD mortality, 2.5% MI mortality, and 8.5% stroke mortality during the COVID-19 pandemic (2020-2021) compared with the prepandemic era (2018-2019). Black individuals had higher excess CVD mortality (13.8%) than White individuals (5.1%; P<.001). This remained consistent across subtypes of CVD, including MI (9.6% vs 1.0%; P<.001), stroke (14.5% vs 6.9%; P<.001), and heart failure (5.1% vs -1.2%; P<.001). CONCLUSION: There has been a significant rise in CVD and subtype-specific mortality during the COVID-19 pandemic that has been persistent despite 2 years since the onset of the pandemic. Excess CVD mortality has disproportionately affected Black compared with White individuals. Further studies targeting and eliminating health care disparities are necessary.

In-hospital and Readmission Outcomes With Percutaneous Balloon Mitral Valvuloplasty.

Percutaneous balloon mitral valvuloplasty (PBMV) is primarily performed for rheumatic mitral stenosis (MS). Therefore, limited data exist on PBMV in countries with a low incidence of rheumatic disease. Using the Nationwide Readmission Database, we examined trends in in-hospital mortality and 30-day readmission among patients who received PBMV for rheumatic and non-rheumatic MS. We also examined the change in 90-day hospitalization rate before vs after PBMV. Between 2016 and 2019, there were 1109 hospitalizations in which patients received PBMV for rheumatic (n = 955, 86.1%) vs non-rheumatic MS (n = 154, 13.9%). The all-cause in-hospital mortality for rheumatic and non-rheumatic MS did not change over time (0.9% → 2.0%, P = 0.94, and 5.9% → 9.5%, P = 0.09 respectively). Similarly, the 30-day readmission for patients with rheumatic and non-rheumatic MS did not change over time (12.4% → 9.9%, P = 0.26, and 4.4% → 10.5%, P = 0.30, respectively). The 90-day all-cause hospitalization rate remained the same before vs after PBMV for rheumatic and non-rheumatic MS (25.5% → 21.8%; P = 0.14, and 24.0% → 33.7%; P = 0.19, respectively). Although no statistically significant change was noted over time for trends in in-hospital mortality, 30-day readmission, or even in the change in 90-day all-cause hospitalizations before and after PBMV for both types of MS, among those with non-rheumatic MS, there was a signal of an increase in the in-hospital mortality, and 30-day readmission, even more, there was 29% relative increase in 90-day hospitalizations after PBMV. Future studies are needed to examine the role of PBMV in patients with non-rheumatic MS.

Reported Pericardial Toxicities Associated with Acute Myelogenous Leukemia Treatments: A Pharmacovigilance Analysis of the FDA Adverse Reporting Database.

Acute myelogenous leukemia (AML) is one of the most common leukemias experienced in adults and conveys significant morbidity and mortality. While the traditional anthracycline based treatments of AML involves cytarabine, developments in alternatives (liposomal cytarabine, fludarabine, cladribine, azacitidine, decitabine), and targeted agents (midostaurin, gilteritinib, enasidenib, ivosidenib, gemtuzumab ozogamicin, and venetoclax) exist. Multiple cardiovascular adverse events, notably pericardial toxicity, have been observed in small studies; however, to date little is known about the comparative pericardial toxicity among these newer regimens. Due to the paucity of data, we sought to investigate the reported pericardial events and mortality associated with treatments for AML. Utilizing the Food and Drug Administration (FDA) Adverse Events Reporting System (FAERS), we identified all adverse events associated with FDA approved treatments for AML (2002-2022). Pericardial events were defined as pericarditis, pericardial effusion and tamponade. We excluded any individuals with age <18 years old. Logistic regression was utilized to identify factors associated with pericardial events. Out of 94,262 reported adverse events, 675 pericardial toxicities were included (243 pericarditis, 479 tamponade). Pericardial events occurred less often in Cladribine (0.3%, P < 0.001), fludarabine (0.4%, P < 0.001), Venetoclax (0.3%, P < 0.001), enasidenib (0.3%, P value < 0.001), and ivosidenib (0.3%, P < 0.001) compared to Cytarabine (0.9%). Tamponade events occurred significantly less often in cladribine (0.1%, P < 0.001), fludarabine (0.4%, P = 0.001), enasidenib (0.1%, P = 0.006), ivosidenib (0.1%, P = 0.01), and venetoclax (0.1%, P < 0.001) compared to cytarabine 0.7%. After adjusting for age and sex, Cladribine (reporting odds ratio [ROR] 0.35 [95% CI 0.18-0.68], P = 0.008) and Fludarabine (ROR 0.65 [0.45-0.92], P = 0.03), venetoclax (ROR 0.57 [0.41-0.79], P < 0.001) remained significantly associated with lower incidence of reported pericardial events. While cytarabine has been the routinely used and/or drug of choice for induction chemotherapy for AML, alternatives like cladribine may have a greater safety profile regarding pericardial toxicities. Future studies should be directed at further investigating cardiovascular safety profiles of AML induction therapy.

Predictors and potential advantages of PERT and advanced therapy use in acute pulmonary embolism.

OBJECTIVES: We sought to examine predictors of pulmonary embolism response team (PERT) utilization and identify those who could benefit from advanced therapy. BACKGROUND: PERT and advanced therapy use remain low. Current risk stratification tools heavily weight age and comorbidities, which may not always correlate with presentation's severity. METHODS: We prospectively studied patients with CT-confirmed PE between January 2019 and December 2019 at our hospital. PERT activation was left to the treating physician. Multivariable analyses were utilized to identify predictors of PERT activation and advanced therapy. Using the log odd ratio of each significant predictor of advanced therapy, we created a scoring system and a score of 2 was associated with the highest use. Primary outcomes were 30- and 90-day all-cause mortality, readmission, and major bleed. RESULTS: Of the 307 patients, PERT was activated in 22.5%. While abnormal vital signs and right ventricular (RV) strain were associated with PERT activation, pulmonary embolism severity index (PESI) was not. Advanced therapy use was significantly higher in the PERT cohort (35% vs 2%). Predictors of advanced therapy use were composite variable (heart rate > 110 or systolic blood pressure < 100 or respiratory rate > 30 or oxygen saturation < 90%) and right-to-left ventricular ratio > 0.9. PERT patients with advanced therapy use, when compared to the no-PERT patients who could have qualified (score of 2), had significantly lower 30- and 90-day mortality and 30-day readmission without difference in major bleed. CONCLUSION: PERT has important therapeutic impact, yet no guidelines to direct activation. We recommend a multidisciplinary approach for higher acuity pulmonary embolism cases and physician education regarding PERT and the scope of advanced therapy use.
