Race, Ethnicity, and Gender Disparities in Acute Myocardial Infarction.

Cardiovascular disease continues to be the leading cause of morbidity and mortality in the United States. Despite advancements in medical care, there remain persistent racial, ethnic, and gender disparity in the diagnosis, treatment, and prognosis of individuals with cardiovascular disease. In this review we seek to discuss differences in pathophysiology, clinical course, and risk profiles in the management and outcomes of acute myocardial infarction and related high-risk states. We also seek to highlight the demographic and psychosocial inequities that cause disparities in acute cardiovascular care.

Comparative Outcomes of Catheter-Directed Thrombolysis Plus Systemic Anticoagulation Versus Systemic Anticoagulation Alone in the Management of Intermediate-Risk Pulmonary Embolism in a Systematic Review and Meta-Analysis.

There are limited and conflicting data on the initial management of intermediate-risk (or submassive) pulmonary embolism (PE). This study sought to compare the outcomes of catheter-directed thrombolysis (CDT) in combination with systemic anticoagulation (SA) to SA alone. A systematic search was conducted in MEDLINE, EMBASE, PubMed, and the Cochrane databases from inception to March 1, 2023 for studies comparing the outcomes of CDT + SA versus SA alone in intermediate-risk PE. The outcomes were in-hospital, 30-day, 90-day, and 1-year mortality; bleeding; blood transfusion; right ventricular recovery; and length of stay. Random-effects models was used to calculate the pooled incidence and risk ratios (RRs) with 95% confidence intervals (CIs). A total of 15 (2 randomized and 13 observational) studies with 10,549 (2,310 CDT + SA and 8,239 SA alone) patients were included. Compared with SA, CDT + SA was associated with significantly lower in-hospital mortality (RR 0.41, 95% CI 0.30 to 0.56, p <0.001), 30-day mortality (RR 0.34, 95% CI 0.18 to 0.67, p = 0.002), 90-day mortality (RR 0.34, 95% CI 0.17 to 0.67, p = 0.002), and 1-year mortality (RR 0.58, 95% CI 0.34 to 0.97, p = 0.04). There were no significant differences between the 2 cohorts in the rates of major bleeding (RR 1.39, 95% CI 0.72 to 2.68, p = 0.56), minor bleeding (RR 1.83, 95% CI 0.97 to 3.46, p = 0.06), and blood transfusion (RR 0.34, 95% CI 0.10 to 1.15, p = 0.08). In conclusion, CDT + SA is associated with significantly lower short-term and long-term all-cause mortality, without any differences in major/minor bleeding, in patients with intermediate-risk PE.

Trends in and predictors of multiple readmissions following heart failure hospitalization: A National wide analysis from the United States.

BACKGROUND: Readmission following Heart failure (HF) hospitalization is common: 25% are readmitted within a month of discharge and ≈50% within 6 months. A small proportion of these patients can have multiple readmissions within this period, adding disproportionately to the health care costs. In this study, we assessed the trends, predictors and costs associated with multiple readmissions using National readmissions database (NRD). METHODS: We queried NRD for HF hospitalizations from 2010 to 2018 using ICD-9/10-CM codes. Multinomial logistic regression was used to compare readmission cohorts, with the multivariable model adjusting for other factors. All analyses accounted for the NRD sampling design were conducted using SAS v. 9.4 with p < 0.05 used to indicate statistical significance. RESULTS: Within the study period, an estimated 6,763,201 HF hospitalizations were identified. Of these, 58% had no readmission; 26% had 1 readmission; and 16% had ≥2 readmissions within 90 days of index hospitalization. There was no statistically significant change in readmission rates during the observation period. Multiple readmissions which accounted for 37% of all readmissions contributed to 57% of readmission costs. Younger age was identified as a predictor of multiple readmissions while sex, comorbidities and the type of insurance were not significantly different from those with single readmission. CONCLUSIONS: Multiple readmissions in HF are common (16%), have remained unchanged between 2010 and 2018 and impose a significant health care cost burden. Future research should focus on identifying these patients for targeted intervention that may minimize excessive readmissions particularly in those patients who are in the palliation phase of HF.

Atrial invasion from primary lung adenocarcinoma extension via the pulmonary vein.

Intravascular extension of lung adenocarcinoma is one of the four defined routes of metastasis to the heart but is rarely described in the literature. This is a rare case of primary lung adenocarcinoma with intravenous extension to the left atrium via the pulmonary vein. A 56-year-old female presented to the hospital with chest tightness and dyspnea. Chest computed tomography revealed a right hilar mass extending through the right superior pulmonary vein into the left atrium. Transthoracic echocardiography revealed a large, partially mobile left atrial mass occupying the entire atrial cavity and affecting mitral valve closure. Endobronchial ultrasound with transbronchial biopsy of the right middle lobe of the lung histologically showed a poorly differentiated adenocarcinoma compatible with the primary lung cancer. The patient was deemed a poor surgical candidate by cardiothoracic surgery due to the extent of metastasis and was started on chemoradiation. The patient's left atrial tumor mass started shrinking in size after starting the treatment. This unique case displaying intravascular extension of lung cancer to the left atrium has rarely been described in the literature.

COVID-19 presenting with myocardial infarction with nonobstructive coronary arteries.

Cardiovascular complications contribute to approximately 40% of all COVID-19-related deaths. Thrombosis in COVID-19 infection is a well-known phenomenon, and the spectrum of thromboembolic diseases related to COVID-19 is wide, with venous thromboembolism being the most common manifestation. We describe a case of myocardial infarction with nonobstructive coronary arteries (MINOCA) that developed in the setting of mild COVID-19 infection. Our case illustrates how COVID-19 can present with MINOCA and highlights the importance of cardiac magnetic resonance imaging in identifying the underlying etiology.

Histoplasmosis presenting as colitis and blood dyscrasias in a patient with systemic lupus erythematosus.

A 28-year-old woman with a history of systemic lupus erythematosus on hydroxychloroquine and steroid therapy presented with fever, dysentery, and thrombocytopenia. Marrow aspirate revealed yeast forms of histoplasmosis. She was treated with liposomal amphotericin B followed by itraconazole with resolution of symptoms and marrow recovery.
