Article Synopsis
- - A 71-year-old woman with a mild case of SARS-CoV-2 had acute myopericarditis diagnosed through various medical tests.
- - This case emphasizes that cardiac issues can occur even without severe COVID-19 symptoms.
- - The exact causes of heart injury from SARS-CoV-2 are unclear and more research is needed to understand if it’s due to direct viral damage or other systemic factors.
Article Synopsis
- The study focuses on patients over 75 years old with sinus node dysfunction who received pacemakers, aiming to understand their outcomes such as heart failure, atrial fibrillation, and mortality rates.
- Out of 102 patients followed for about 806 days, 35.3% faced heart failure, 46.1% had paroxysmal atrial fibrillation, and 28.4% died, with nearly half of the deaths being cardiac-related.
- The results indicate that patients with dual-chamber pacemakers that minimize ventricular pacing had significantly lower rates of heart failure and overall mortality compared to those with conventional pacing, suggesting that this approach is beneficial for older patients.
A rare life-threatening complication during percutaneous cryoablation of an adrenal gland metastasis from a lung carcinoma is reported. The patient presented hypertensive crisis at the beginning of the thawing cycle, followed by electrocardiographic change which necessitated interruption of the procedure and his transfer to the intensive care unit with suspicion of heart infarct. There was a slight increase in cardiac enzyme levels, and ventricular angiography demonstrated transient hypokinesis-dyskinesis of the mid left ventricular segments without apical involvement, while the coronary arteries showed no significant stenosis on coronarography.

MP prothrombotic and proinflammatory properties may be crucial for coronary prognosis. Elevated amounts of circulating procoagulant MP were described in diabetes mellitus (DM), and could be of particular significance in a MI context.
