BACKGROUND: More than 90% of acute stroke patients have measurable cardiovascular sequelae, but we have been often overlooked in formal discussions of treatment. If we estimate the incidence of myocardial injury in patient with spontaneous SAH, we may figure the possibility of cardiac dysfunction in such patients. This study was designed to investigate the incidence of myocardial injury in patients with spontaneous SAH using cardiac troponin I(cTnI). METHODS: A prospective single emergency center study was performed to determined preoperative incidence of unrecognized cardiac injury in patients suffering spontaneous SAH. We include the spontaneous SAH patients who underwent serum measurements of the cardic troponin I immediately upon admission last six month period. ECG, CK, CK-MB and myoglobin were also performed at admission. We excluded the spontaneous SAH patients who had past history of myocardial ischemia and ECG abnormality. RESULTS: Fifty-two patients(34 females, 18 males) with spontaneous SAH were studied prospectively. 18 patients(34.6% of the total study population) had cTnI level above 0.5ng/ml. ECG was performed in 52 patients and was abnormal in 15 of the 52 patients(28.8%). CONCLUSION: The measurement of cTnI has provided physicians with a myocardial marker that has a cardiac sensitivity for cardiac injury equal to that of CK-MB yet with greater specificity. So, cardiac troponin I is useful to estimate the incidence of myocardial injury in patients with spontaneous SAH. And we may estimate the possibility of cardiac dysfunction in such patients. This knowledge will hopefully aid in the care and improve the outcome.

In diamnionic dichorionic twins, the type of placenta consists of fused and separate types. The expansion of one twin placenta often occurs in the direction of the other implantation site in fused type. Placental development often leads to collision, and the growth of one or both placentas may be hindered, which can cause intrauterine growth restriction (IUGR). We represent a single case of one placental implantation above the another which caused IUFD in one fetus in diamnionic dichorionic twin pregnancy with a brief review of literatures.
