[Prophylactic intraaortic balloon pumping preserves left ventricular systolic function in acute anterior myocardial infarction without cardiogenic shock].
Left ventricular function and prognosis were evaluated in patients with acute myocardial infarction who underwent primary percutaneous coronary intervention supported by intraaortic balloon pumping. ⋯ Prophylactic use of intraaortic balloon pumping starting prior to primary percutaneous coronary intervention preserves the convalescent left ventricular systolic function in patients with high risk for anticipated cardiac events after anterior acute myocardial infarction without cardiogenic shock.

[Clinical impact of nephropathy induced by contrast medium in patients with acute myocardial infarction undergoing emergent coronary angiography].
The incidence of contrast-induced nephropathy (CIN) after coronary angiography and the prognostic value in patients with acute myocardial infarction remains to be determined. This study investigated the frequency, predictors of CIN, and the prognostic significance of CIN in acute myocardial infarction patients undergoing emergent coronary angiography. ⋯ CIN was an independent predictor of both in-hospital and long-term mortality in acute myocardial infarction patients undergoing emergent coronary angiography. Preexisting renal insufficiency was associated with subsequent CIN.

Comparative Study[Effect of collateral circulation on myocardial protection in patients with acute myocardial infarction: comparison of technetium-99m-tetrofosmin myocardial single photon emission computed tomography and coronary angiography].
Evaluation of myocardial blood flow from collateral vessels into the infarct area has been estimated by coronary angiography. In patients with acute myocardial infarction with Thrombolysis in Myocardial Infarction (TIMI) 0 flow, myocardial tracer uptake on single photon emission computed tomography (SPECT) images can predict the collateral blood flow in the infarct area if technetium (Tc)-99m-tetrofosmin was administered before recanalization. The present study investigated whether collateral blood flow evaluated by myocardial scintigraphy is a good predictor of myocardial salvage in patients with acute myocardial infarction. ⋯ The collateral flow evaluated by scintigraphy was significantly correlated with myocardial viability.

Case ReportsSilent pulmonary artery dissection in a patient with Eisenmenger syndrome due to ventricular septal defect: a case report.
A 62-year-old woman was admitted to our hospital because of fever in August 2002. She had been treated under a diagnosis of Eisenmenger syndrome with ventricular septal defect since 1988. On admission, echocardiography and color Doppler echocardiography revealed a markedly enlarged pulmonary artery with a mobile flap, and dissection of the pulmonary artery. ⋯ She had no chest pain, but fever might have been a sign of dissection in this patient. Longstanding pulmonary hypertension may cause dissection, which may lead to sudden death or pulmonary hemorrhage often seen in patients with Eisenmenger syndrome. Our patient was a rare survivor without serious bleeding complication.
