Published: May 2003

A young woman presented with marked alterations in the ECG without cardiological symptoms or evidence of structural heart disease after further evaluation. There was evidence of vitamin deficiency and the ECG normalized after 10 days of treatment with vitamins. Similar alterations have been described in several experimental studies with rats, but this is the first case reported in humans.

Unlabelled: is a protozoan parasite that causes human and animal African trypanosomiases (HAT and AAT). Cardiac symptoms are commonly reported in HAT patients, and intracardiac parasites with accompanying myocarditis have been observed in both natural hosts and animal models of infection. Despite the importance of as a cause of cardiac dysfunction and the dramatic socioeconomic impact of African trypanosomiases in sub-Saharan Africa, there are currently no reproducible murine models of associated cardiomyopathy.

Background: Subarachnoid hemorrhage (SAH) is characterized by intense central inflammation, leading to substantial post-hemorrhagic complications such as vasospasm and delayed cerebral ischemia. Given the anti-inflammatory effect of transcutaneous auricular vagus nerve stimulation (taVNS) and its ability to promote brain plasticity, taVNS has emerged as a promising therapeutic option for SAH patients. However, the effects of taVNS on cardiovascular dynamics in critically ill patients, like those with SAH, have not yet been investigated.

Objectives: To assess the clinical course and long-term outcomes of complicated and uncomplicated AM in Saudi Arabia. Acute myocarditis (AM) can have different presentations and outcomes based on different factors, one of which is left ventricular ejection fraction (LVEF).

Methods: Data from 382 patients with suspected AM, admitted between January 2016 and October 2023, were reviewed.

We present a case of a 73-year-old woman with a medical history significant for hyperlipidemia, on pravastatin, who developed Takotsubo cardiomyopathy following a diagnosis of osteoporosis. She presented to the Emergency Department with acute transient left arm pain that resolved spontaneously. Investigations revealed elevated troponin levels, non-specific electrocardiographic changes, no significant coronary artery disease on angiography, and left ventricular systolic dysfunction, findings consistent with Takotsubo cardiomyopathy.
