Effect of Hematologic Parameters on Microvascular Reperfusion in Patients With ST-Segment Elevation Myocardial Infarction Treated With Primary Percutaneous Coronary Intervention.

Objectives: Despite the significant role of certain hematologic parameters in reperfusion injury, their relationship with microvascular reperfusion remains not well understood. Therefore, our objective was to evaluate the relationship between hematologic parameters at admission and microvascular reperfusion in patients with ST-segment elevation myocardial infarction (STEMI) treated with primary percutaneous coronary intervention (primary PCI).

Methods: A total of 213patients (mean age: 57.

Predischarge ST segment and T wave patterns in predicting left ventricular function and myocardial viability in Q wave anterior myocardial infarction patients.

The aim of this study was to investigate the correlation between ECG changes prior to discharge and findings of early low dose dobutamine stress echocardiography (LDSE) performed in 6 +/- 2 days, in patients experiencing their first acute anterior MI. A total of 62 patients admitted with their first acute anterior MI were divided into three groups according to the findings of electrocardiograms performed on the 7-10th days: group A, isoelectric ST and negative or positive T wave; group B, ST elevation (> 0.1 mV) and negative T wave; and group C, ST elevation and positive T wave.

The relationship between terminal QRS complex distortion and early low dose dobutamine stress echocardiography in acute anterior myocardial infarction.

Although the damage in myocardial infarction has been demonstrated to be related with the magnitude and number of ST elevation, its relation with terminal distortion of QRS is unclear. The relationship between terminal QRS distortion in ECGs on admission and the results of early low dose dobutamine stress echocardiography (LDSE) performed 6 +/- 2 days later was investigated. Patients admitted to our clinic within the first six hours of their chest pain and without a prior infarction diagnosis were divided into two groups based on the admission electrocardiogram as the absence (QRS-, n = 33) or presence (QRS+, n = 29) of distortion of the terminal portion of the QRS in > or = 2 leads (QRS+; J point at > 50% of the R wave amplitude in lateral leads or presence of ST elevation without S wave in leads V1-V3).

The relationship of ST segment elevation shape with preserved myocardium and signal-averaged electrocardiography in acute anterior myocardial infarction.

Although a relation between magnitude of ST segment elevation and myocardial damage has been shown in the early period of acute myocardial infarction (AMI), such a relation between the shape of the ST segment elevation, myocardial damage, and the clinical course remains obscure. For this purpose 62 first anterior AMI patients admitted in the first 6h were enrolled for the study. On the basis of precordial V3 derivation prior to thrombolytic therapy, the shape of the ST elevation was separated into three groups: concave (n = 26), straight (n = 24), or convex types (n = 12).

Cardiac hydatid cysts located in both the left ventricular apex and the intraventricular septum: case report.

Cardiac hydatid cyst is rarely encountered and constitutes 0.5%-2% of all hydatid cases. Although left ventricular (LV) location for hydatid cysts has been frequently reported, the involvement of both the left ventricle and the interventricular septum (IVS) has not been previously reported in the literature.
