In-hospital outcomes in unhoused patients with cardiogenic shock in the United States: Insights from The National Inpatient Sample 2011-2019.

BACKGROUND: Unhoused patients face significant barriers to receiving health care in both the inpatient and outpatient settings. For unhoused patients with heart failure who are in extremis, there is a lack of data regarding in-hospital outcomes and resource utilization in the setting of cardiogenic shock (CS). HYPOTHESIS: Unhoused patients hospitalized with CS have increased mortality and decreased use of invasive therapies as compared to housed patients. METHODS: The National Inpatient Sample (NIS) database was queried from 2011 to 2019 for relevant ICD-9 and ICD-10 codes to identify unhoused patients with an admission diagnosis of CS. Baseline characteristics and in-hospital outcomes between patients were compared. Binary logistic regression was used to adjust outcomes for prespecified and significantly different baseline characteristics (p < .05). RESULTS: We identified a weighted sample of 1 202 583 adult CS hospitalizations, of whom 4510 were unhoused (0.38%). There was no significant difference in the comorbidity adjusted odds of mortality between groups. Unhoused patients had lower odds of receiving mechanical circulatory support, left heart catheterization, percutaneous coronary intervention, or pulmonary artery catheterization. Unhoused patients had higher adjusted odds of infectious complications, undergoing intubation, or requiring restraints. CONCLUSIONS: These data suggest that, despite having fewer traditional comorbidities, unhoused patients have similar mortality and less access to more aggressive care than housed patients. Unhoused patients may experience under-diuresis, or more conservative care strategies, as evidenced by the higher intubation rate in this population. Further studies are needed to elucidate long-term outcomes and investigate systemic methods to ameliorate barriers to care in unhoused populations.

Pharmacotherapies in Heart Failure With Preserved Ejection Fraction: A Systematic Review and Network Meta-Analysis.

Various pharmacotherapies exist for heart failure with preserved ejection fraction (HFpEF), but with unclear comparative efficacy. We searched EMBASE, Medline, and Cochrane Library from inception through August 2021 for all randomized clinical trials in HFpEF (EF >40%) that evaluated beta-blockers, mineralocorticoid receptor antagonist (MRA), angiotensin-converting enzyme inhibitors (ACE), angiotensin receptor blockers (ARB), angiotensin receptor-neprilysin inhibitor (ARNI), and sodium-glucose cotransporter-2 inhibitors (SGLT2i). Outcomes assessed were cardiovascular mortality, all-cause mortality, and HF hospitalization. A frequentist network meta-analysis was performed with a random-effects model. We included 22 randomized clinical trials (30,673 participants; mean age = 71.7 ± 4.2 years; females = 49.3 ± 7.7%; median follow-up = 24.4 ± 11.1 months). Compared with placebo, there was no statistically significant difference in cardiovascular mortality [beta-blockers; odds ratio (OR) 0.79 (0.46-1.34), MRA; OR 0.90 (0.70-1.14), ACE OR 0.95 (0.59-1.53), ARB; OR 1.02 (0.87-1.19), ARNI; OR 0.97 (0.74-1.26) and SGLT2i; OR 1.00 (0.84-1.18)] or all-cause mortality [beta blockers; OR 0.75 (0.54-1.04), MRA; OR 0.90 (0.75-1.08) ACE; OR 1.05 (0.71-1.54), ARB; OR 1.03 (0.91-1.15), ARNI; OR 0.99 (0.82-1.20) and SGLT2i; OR 1.00 (0.89-1.13)]. The certainty in these estimates was low or very low. There was a significantly reduction in HF hospitalization with the use of SGLT2i [OR 0.71 (0.62-0.82), moderate certainty], ARNI [OR 0.77 (0.63-0.94), low certainty], and MRA [OR 0.81 (0.66-0.98), moderate certainty]; with corresponding P scores of 0.84, 0.68, and 0.58, respectively. In HFpEF, the use of beta-blockers, MRA, ACE/ARB/ARNI, or SGLT2i was not associated with improved cardiovascular or all-cause mortality. SGLT2i, ARNI, and MRA reduced the risk of HF hospitalizations.

Impact of Body Mass Index on Mortality in Hospitalized Patients With Hypertrophic Cardiomyopathy.

Although obesity is associated with increased phenotypic expression in patients with hypertrophic cardiomyopathy (HC), the effect of body mass index (BMI) on in-hospital mortality in hospitalized patients with HC has not been established. We evaluated the National Inpatient Sample in the United States to identify all adults with HC hospitalized for cardiac illnesses between 2008 and 2017. Using International Classification of Diseases codes, the study cohort was stratified into underweight (BMI ≤19.9 kg/m2), normal weight (BMI 20.0 to 24.9 kg/m2), overweight (BMI 25.0 to 29.9 kg/m2), class I (BMI 30.0 to 34.9 kg/m2), class II (BMI 35.0 to 39.9 kg/m2), and class III (BMI ≥40.0 kg/m2) obesity. Multiple logistic regression analysis was used to analyze the independent association of various BMI categories and mortality. The study included a total of 2,392,325 hospitalizations (mean age-66.1 ± 12.2 years; 42.0% female). The patients with class III obesity (adjusted mortality rate [AMR] 3.3%, adjusted odds ratio [AOR] 1.53, 95% confidence interval [CI] 1.29 to 1.82, p <0.001) and underweight patients (AMR 4.4%, AOR 2.07, 95% CI 1.74-2.46, p <0.001) had higher in-hospital mortality whereas overweight patients (AMR 1.6%, AOR 0.26, 95% CI 0.19 to 0.34, p <0.001), patients with class I obesity (AMR 0.8%, AOR 0.35, 95% CI 0.27 to 0.45, p <0.001) and patients with class II obesity (AMR 0.8%, AOR 0.34, 95% CI 0.26 to 0.45, p <0.001) had lower mortality compared with patients with normal BMI (AMR 2.9%). In conclusion, BMI has a nonlinear U-shaped relation with in-hospital mortality in patients with HC. The patients who were underweight and morbidly obese had significantly higher mortality, whereas those patients with overweight, class I, and class II obesity had lower mortality than normal BMI.

Balloon pulmonary angioplasty for chronic thromboembolic pulmonary hypertension.

Chronic thromboembolic pulmonary hypertension (CTEPH) is a form of pulmonary hypertension (PH) caused by thromboembolic disease with the secondary remodeling of the pulmonary vessels. The primary treatment of CTEPH is pulmonary thromboendarterectomy (PTE). However, some patients are not candidates for PTE because of surgically inaccessible thrombi or high operative risk and can be candidates for balloon pulmonary angioplasty (BPA), an emerging, lower risk treatment. This review discusses the patient selection, the technique, and comprehensive review of reported outcomes following BPA. BPA techniques have improved over the years, and so has its safety profile. Recent data show that after several sessions of BPA, patients who were not eligible for PTE had improvement in their hemodynamic profile, functional capacity, and 6-minute walk distance. Studies have shown that compared to riociguat, BPA has shown significant improvement in the functional capacity and hemodynamic measurements. Reperfusion pulmonary edema is a common complication after PTE and BPA, which may be due to vessel injury rather than pulmonary extravasation. Rates of complications have decreased especially after the use of optical coherence tomography, which helps in proper sizing of the balloons. Patients with CTEPH who are ineligible for PTE should be evaluated for BPA. In addition to medical therapy, BPA has shown promising clinical and hemodynamic outcomes in patients with CTEPH.

Mental health disorders among patients with acute myocardial infarction in the United States.

OBJECTIVE: To assess the prevalence, temporal trends and sex- and racial/ethnic differences in the burden of mental health disorders (MHD) and outcomes among patients with myocardial infarction (MI) in the United States. METHODS: Using the National Inpatient Sample Database, we evaluated a contemporary cohort of patients hospitalized for acute MI in the United States over 10 years period from 2008 to 2017. We used multivariable logistic regression analysis for in-hospital outcomes, yearly trends and estimated annual percent change (APC) in odds of MHD among MI patients. RESULTS: We included a total sample of 6,117,804 hospitalizations for MI (ST elevation MI in 30.4%), with a mean age of 67.2 â€‹± â€‹0.04 years and 39% females. Major depression (6.2%) and anxiety disorders (6.0%) were the most common MHD, followed by bipolar disorder (0.9%), schizophrenia/psychotic disorders (0.8%) and post-traumatic stress disorder (PTSD) (0.3%). Between 2008 and 2017, the prevalences significantly increased for major depression (4.7%-7.4%, APC +6.2%, p â€‹< â€‹.001), anxiety disorders (3.2%-8.9%, APC +13.5%, p â€‹< â€‹.001), PTSD (0.2%-0.6%, +12.5%, p â€‹< â€‹.001) and bipolar disorder (0.7%-1.0%, APC +4.0%, p â€‹< â€‹.001). Significant sex- and racial/ethnic-differences were also noted. Major depression, bipolar disorder or schizophrenia/psychotic disorders were associated with a lower likelihood of coronary revascularization. CONCLUSION: MHD are common among patients with acute MI and there was a concerning increase in the prevalence of major depression, bipolar disorder, anxiety disorders and PTSD over this 10-year period. Focused mental health interventions are warranted to address the increasing burden of comorbid MHD among acute MI.

Minnelide, a prodrug, inhibits cervical cancer growth by blocking HPV-induced changes in p53 and pRb.

HPV-induced cervical cancer is one of the prevalent gynecological cancers world-wide. In the present study, we determined the efficacy of Minnelide, a prodrug which is converted to its active form (Triptolide) in vivo against cervical cancer cells. Our studies show that Triptolide inhibited HPV-16 and HPV-18 positive cells at nanomolar concentrations. Tumor cells treated with Triptolide failed to grow in 3-D cultures in a concentration-dependent manner. Triptolide markedly reduced E6 and E7 transcript levels. Further studies revealed that exposure to Triptolide increased the levels of p53 and pRb. As a consequence, Caspase-3/7 activation and apoptosis was induced in cervical cancer cells by Triptolide. Subsequently, we evaluated the efficacy of Minnelide in xenotransplantation models of cervical cancer. Minnelide at very low doses effectively inhibited the growth of established cervical cancers in all the three animal models tested. Furthermore, Minnelide treatment was more effective when combined with platinum-based chemotherapy. These studies show that Minnelide can be used to inhibit the growth of cervical cancer.

Nuclear Imaging for the Assessment of Cardiotoxicity from Chemotherapeutic Agents in Oncologic Disease.

PURPOSE OF REVIEW: In this review, we summarize the major known cardiac toxicities of common chemotherapeutic agents and the role of nuclear cardiac imaging for the surveillance and assessment of cancer therapeutics-related cardiac dysfunction in routine clinical practice. RECENT FINDINGS: Cardiotoxicity from chemotherapy causes a significant mortality and limits potentially life-saving treatment in cancer patients. Close monitoring of cardiac function during chemotherapy is an accepted method for reducing these adverse effects especially in patients with cancer therapeutics-related cardiac dysfunction. Nuclear imaging is a sensitive, specific, and highly reproducible modality for assessment of cardiac function. Nuclear imaging techniques including equilibrium radio nucleotide angiography, myocardial perfusion imaging, and novel experimental molecular imaging are the various objective tools available in addition to conventional echocardiography and cardiac magnetic resonance imaging in the surveillance, assessment, and follow-up of cancer therapeutics-related cardiac dysfunction.

Obesity and Outcomes Following Cardiogenic Shock Requiring Acute Mechanical Circulatory Support.

BACKGROUND: The association of obesity on outcomes in patients with cardiogenic shock requiring acute mechanical circulatory support has not been thoroughly investigated. METHODS: We evaluated the National Readmission Database for adults with either acute myocardial infarction or heart failure complicated by cardiogenic shock requiring acute mechanical circulatory support between January 2016 and November 2017. Exposure was assessed using International Classification of Diseases, Tenth Revision codes for the degree of obesity with the reference being body mass index (BMI) of 20.0 to 29.9 group. Multiple logistic regression and Cox regression analysis were used to analyze in-hospital mortality and 30-day readmission, respectively. RESULTS: The survey-weighted sample included a total of 35 555 hospitalizations with a mean age of 65.4±0.2 years and 29.8% females. Obesity was associated with higher in-hospital mortality (no obesity, 26.4% [BMI, 20.0-29.9] versus class I obesity, 25.0% [BMI, 30.0-34.9] versus class II obesity, 28.7% [BMI, 35.0-39.9] versus class III obesity, 34.9% [BMI, ≥40]; P<0.001). On stratified analysis, compared with a nonobese phenotype, younger adults (age <60) with class II and class III obesity (odds ratio, 1.9 [95% CI, 1.1-3.5], P=0.02; odds ratio, 2.1 [95% CI, 1.2-3.7], P=0.01) and older adults (age ≥60) with class III obesity (odds ratio, 1.7 [95% CI, 1.2-2.4], P=0.005) had higher mortality. There was no association between the degree of obesity and 30-day readmission. CONCLUSIONS: Among adults with acute myocardial infarction or acute heart failure resulting in cardiogenic shock requiring acute mechanical circulatory support, younger adults with class II and class III obesity and older patients with class III obesity have a higher risk of in-hospital mortality compared with nonobese patients.

Characteristics and Outcomes of Patients 80 Years and Older Hospitalized With Coronavirus Disease 2019 (COVID-19).

Patients older than 65 years hospitalized with COVID-19 have higher rates of intensive care unit admission and death when compared with younger patients. Cardiovascular conditions associated with COVID-19 include myocardial injury, acute myocarditis, cardiac arrhythmias, cardiomyopathies, cardiogenic shock, thromboembolic disease, and cardiac arrest. Few studies have described the clinical course of those at the upper extreme of age. We characterize the clinical course and outcomes of 73 patients with 80 years of age or older hospitalized at an academic center between March 15 and May 13, 2020. These patients had multiple comorbidities and often presented with atypical clinical findings such as altered sensorium, generalized weakness and falls. Cardiovascular manifestations observed at the time of presentation included new arrhythmia in 7/73 (10%), stroke/intracranial hemorrhage in 5/73 (7%), and elevated troponin in 27/58 (47%). During hospitalization, 38% of all patients required intensive care, 13% developed a need for renal replacement therapy, and 32% required vasopressor support. All-cause mortality was 47% and was highest in patients who were ever in intensive care (71%), required mechanical ventilation (83%), or vasopressors (91%), or developed a need for renal replacement therapy (100%). Patients older than 80 years old with COVID-19 have multiple unique risk factors which can be associated with increased cardiovascular involvement and death.

Rate, causes, and predictors of 90-day readmissions and the association with index hospitalization coronary revascularization following non-ST elevation myocardial infarction in the United States.

OBJECTIVES: To assess the causes and predictors of readmission after NSTEMI. BACKGROUND: Studies on readmissions following non-ST elevation myocardial infarction (NSTEMI) are limited. We investigated the rate and causes for readmission and the impact of coronary revascularization on 90-day readmissions following a hospitalization for NSTEMI in a large, nationally representative United States database. METHODS: We queried the National Readmission Database for the year 2016 using appropriate ICD-10-CM/PCS codes to identify all adult admissions for NSTEMI. We determined the 90-day readmissions for major adverse cardiac events (MACE). All-cause readmission was a secondary endpoint. The association between coronary revascularization and the likelihood of readmission was analyzed using multivariate Cox regression analysis. RESULTS: A total of 296,965 adult discharges following an admission for NSTEMI were included in this study. The rate of readmissions for MACE was 5.2% (n = 15,637) and for any cause was 18.0% (n = 53,316). 38% of MACE readmissions and 40% of all-cause readmissions occurred between 30- and 90-days following the index hospitalization. During index hospitalization, 51.0% underwent coronary revascularization (40.8% with PCI and 10.2% with CABG). This was independently predictive of a lower risk of 90-day readmission for MACE (adjusted HR 0.59, 95% confidence interval (CI) 0.56-0.63, p < .001) and for any cause (adjusted HR 0.65, 95% CI 0.63-0.67, p < .001). In-hospital mortality for MACE readmissions was significantly higher compared to that of index hospitalization (3.8% vs. 2.6%, p < .001). CONCLUSION: Readmissions following NSTEMI carry higher mortality than the index hospitalization. Coronary revascularization for NSTEMI is associated with a lower readmission rate at 90 days.

Rate, Causes, and Predictors of 30-Day Readmission Following Hospitalization for Acute Pericarditis.

BACKGROUND: Acute pericarditis is a frequent cause of hospitalization in the United States. Although recurrence of this condition is common, few studies have investigated hospital readmissions in this patient population. METHODS: We queried the National Readmission Database for the years 2016 and 2017 to identify adult admissions for acute pericarditis, and analyzed the data for 30-day readmission. Using multivariate Cox regression analysis, we identified clinical characteristics that were independently predictive of hospital readmission within 30 days. RESULTS: A total of 21,335 patients (mean age 52.5 ± 0.2 years; 38.3% women) who were discharged following hospitalization for acute pericarditis were included. The rate of 30-day readmission was 12.9% (n = 2740). Increasing age (adjusted hazard ratio [HR] 1.05 per 5-year increase; 95% confidence interval [CI], 1.02-1.09; P < 0.001), female sex (adjusted HR 1.33; 95% CI, 1.18-1.49; P < 0.001), dialysis dependence (adjusted HR 1.70; 95% CI, 1.30-2.22; P < 0.001), chronic obstructive pulmonary disease (adjusted HR 1.27; 95% CI, 1.11-1.45; P < 0.001), and presence of pericardial effusion (adjusted HR 1.24; 95% CI, 1.04-1.49; P = 0.02) were independently associated with a higher risk of readmission. In-hospital mortality was significantly higher after readmission than for the index hospitalization (3.4% vs 1.0%, P < 0.001). CONCLUSION: After hospitalization for acute pericarditis, readmission within 30 days is common and is associated with increased mortality. Identification of characteristics associated with a higher risk of readmission may lead to focused interventions to improve outcomes.
