Cardiac Vulnerability to Cerebrogenic Stress as a Possible Cause of Troponin Elevation in Stroke Stroke
ConclusionsCertain cardiac and neurological conditions in acute ischemic stroke may contribute to troponin elevation. The proposed concept of cardiac vulnerability to cerebrogenic stress can be a practical interpretation of troponin elevation and electrocardiography abnormalities in stroke patients.

Low Homoarginine Levels in the Prognosis of Patients With Acute Chest Pain Coronary Heart Disease
Conclusion Low plasma homoarginine was identified as a risk marker for incident MACEs in patients with acute chest pain, in particular, in those with elevated hsTnI. Impaired homoarginine was associated with prevalent AF. Further studies are needed to investigate the link to AF and evaluate homoarginine as a therapeutic option for these patients.

Atrial Fibrillation Patterns and Risks of Subsequent Stroke, Heart Failure, or Death in the Community Arrhythmia and Electrophysiology
Conclusions In our community-based AF sample, only 10% had AF without early-term (2-year) recurrence. Compared with individuals without 2-year AF recurrences, the 10-year prognosis was worse for individuals with either sustained or recurrent AF. Our proposed AF classification algorithm may be applicable in longitudinal datas ets.
