Dobutamine in the Management of Advanced Heart Failure.

: The potential harm and clinical benefits of inotropic therapy in patients with decompensated heart failure with reduced ejection fraction or advanced heart failure were debated for three decades. Nonetheless, confronted with a dismal quality of life in the last months to years of life, continuous home inotropic therapy has recently gained traction for palliative therapy in patients who are not candidates for left ventricular mechanical circulatory support or heart transplantation. : As continuous inotropic therapy is only considered for patients who experience symptomatic relief and display objective evidence of improvement, clinical equipoise is no longer present, and randomized controlled trials are hard to conduct.

Post-COVID Sequelae: From Lung Disease to Long Disease.

COVID-19 can have both an acute phase and post-acute phase of illness termed post-COVID sequelae, or "long Covid." In this case, a 66-year-old woman with a past medical history of reactive airway disease was admitted for shortness of breath twice.

Severe Shivering as an Adverse Effect of Regadenoson Myocardial Perfusion Imaging.

Regadenoson myocardial perfusion imaging (MPI) is a widely used screening study for patients with an intermediate pretest probability of coronary artery disease (CAD). Via selective agonism of the adenosine A2A receptor, regadenoson can induce coronary steal, revealing stenotic vessel territory through transient ischemia. Common side effects of this medication include chest pain, shortness of breath, nausea, vomiting, atrioventricular block, seizure, and allergic reactions.
