Thrombotic thrombocytopenic purpura (TTP) is a multisystem disease characterized by disseminated thrombus formation in the arterioles and capillaries. Patients usually present with weakness, subtle mental changes, fever, and acute kidney injury. Cardiac symptoms, such as chest pain or arrhythmia, have been reported but were rarely the sole presenting symptom. We report the case of a 68-year-old woman with acute non-ST-elevation myocardial infarction who was found to have TTP. Prompt diagnosis of TTP is essential because traditional approaches to manage an acute coronary event, inclusive of dual antiplatelet therapy and percutaneous coronary intervention, might be contraindicated due to an increased risk of bleeding. Early administration of steroids and urgent initiation of plasmapheresis to improve platelet count would be crucial initial steps in the management of these patients.

Hypertrophic cardiomyopathy (HCM) is the most common genetic cardiomyopathy resulting from a mutation in one of several cardiac sarcomeric proteins

Heart failure (HF) therapeutics have advanced significantly over the past few years

Nonelective transcatheter aortic valve replacement (TAVR) requires additional research to be fully understood. Using the National Inpatient Sample database (2016-2019), we conducted a retrospective cohort study comparing nonelective vs elective TAVR. The primary outcome of interest was the in-hospital mortality rate among patients undergoing nonelective TAVR, compared to that among patients undergoing elective TAVR. We matched patients in a greedy nearest-neighbor 1:1 model and multivariable logistic regression, which was adjusted for demographics, hospital factors, and comorbidities, and was used to compare mortality in our matched cohort. Each cohort had 4389 patients in each cohort. When adjusted for age, race, sex, and comorbidities, nonelective TAVR patients had 1.99 times higher odds of suffering in-hospital mortality compared to elective admissions (adjusted odds ratio 1.99, 95% confidence interval: 1.42-2.81; P < 0.001). When separated by transfer status, nonelective patients admitted as regular hospital admissions or transferred from other acute-care centres also had higher odds of suffering in-hospital mortality compared to elective admissions. Our findings illustrate that nonelective TAVR patients are a vulnerable population that require additional medical support in the acute-care setting. As the demand for TAVR increases, further discussions regarding access to healthcare in underserved regions, the national physician shortage, and the future of the TAVR industry are imperative.

One of the major risk factors for coronary atherosclerosis is the gradual formation and maturation of coronary atherosclerotic plaque (CAP)
