COVID-19 reinfection: the role of natural immunity, vaccines, and variants.

The COVID-19 pandemic has altered innumerable lives. Although recent mass vaccinations offer a glimmer of hope, the rising death toll and new variants continue to dominate the current scenario. As we begin to understand more about SARS-CoV-2 infections, the territory of reinfections with COVID-19 remains unexplored.

STEMI and COVID-19: Unmasking failures and opportunities to enhance future care.

Increased door‐to‐balloon times, higher initial and peak troponins were seen during the early surge of COVID‐19 pandemic. Patient‐related concerns, administrative hospital protocols and provider uneasiness may have all played a role in patient's reluctance to access care for emergent conditions. There is an urgent need for hospital systems to address the public messaging to encourage patients to seek evidence‐based care when needed even during a pandemic.

Bronchogenic Cyst Presenting as Acute Pericarditis.

Bronchogenic cysts are speculated to arise from abnormal budding of the foregut tissue during embryogenesis. Around 90% of mediastinal bronchogenic cysts are asymptomatic, and a small percentage of them present with chest pain and dyspnea. Pericardial effusion is one of the manifestations described; however, pericarditis has not been widely reported.

Shockwave Intravascular Lithotripsy Via Exclusive Pedal Approach for the Treatment of Complicated Peripheral Arterial Disease.

Shockwave intravascular lithotripsy for the treatment of peripheral arterial disease is routinely performed via femoral artery access. In patients with complex femoropopliteal disease, this traditional approach is not feasible. To address this situation, we used an exclusive pedal access approach along with other adjunctive treatments, resulting in a successful outcome.

Predictive risk stratification using HEART (history, electrocardiogram, age, risk factors, and initial troponin) and TIMI (thrombolysis in myocardial infarction) scores in non-high risk chest pain patients: An African American urban community based hospital study.

Validated risk scoring systems in African American (AA) population are under studied. We utilized history, electrocardiogram, age, risk factors, and initial troponin (HEART) and thrombolysis in myocardial infarction (TIMI) scores to predict major adverse cardiovascular events (MACE) in non-high cardiovascular (CV) risk predominantly AA patient population.A retrospective emergency department (ED) charts review of 1266 chest pain patients where HEART and TIMI scores were calculated for each patient.
