Acute Myocarditis and Heart Failure Associated with Multisystem Inflammatory Syndrome in Adults: A Rare Sequela of Coronavirus 2 Infection.

During the current pandemic, acute coronavirus disease 2019 (COVID-19) due to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) provokes overwhelming inflammatory response leading to a wide range of clinical presentations including, a rare multisystem inflammatory syndrome and cardiac injury. Not only during the acute phase of the disease but a delayed immunologic response to SARS-CoV-2 infection among people with hyperinflammatory illness several weeks postacute phase of the infection is recently recognized. We report a young adult male who presented with acute myocarditis and heart failure associated with laboratory evidence of hyperinflammatory syndrome 5 weeks after a full recovery from COVID-19 infection. We believe that health-care providers need to be aware and recognize this syndrome as a rare sequela of COVID-19 infection.

A Case Report of Severe Dehydration Associated With Acute Kidney Injury Causing Acute ST-Segment Elevation Myocardial Infarction.

The initial electrocardiogram finding in the setting of acute myocardial infarction typically shows either persistent ST-segment elevation or non-ST-segment elevation. In young adults, when coronary angiography is performed, can further classify the patient with an occluded vessel and those with non-occluded coronary arteries. In these subgroups, myocardial infarction can be explained on the basis of coronary artery thrombosis, embolization, spontaneous coronary artery dissection, myocardial bridging, coronary aneurysms, ectasia, anomalous origin of coronary arteries coronary microvascular dysfunction, and vasospasm, or a combination of these factors. We describe a 37-year-old male with a history of chest pain and electrocardiographic evidence of acute myocardial infarction who worked many hours under the sun before being presented to the emergency department. The initial laboratory tests showed evidence of acute kidney injury. He underwent a rescue coronary angiogram due to failed initial medical reperfusion therapy with Tenecteplase, which revealed occluded of the distal left anterior descending (LAD) artery with a minor lesion in proximal LAD and right coronary artery. Our patient experienced acute myocardial infarction owing to severe dehydration. This case is important as it highlights that severe dehydration can be considered one of the triggering factors for acute myocardial infarction in young men who are at risk. Proper hydration could be a preventive measure.
