Among patients with unstable angina or myocardial infarction without ST-segment elevation, prasugrel did not significantly reduce the frequency of the primary end point, as compared with clopidogrel, and similar risks of bleeding were observed.

We aimed to investigate the relationship between the extent of venous thromboembolism (VTE) and nonspecific inflammatory markers such as neutrophil to lymphocyte ratio (NLR) and high-sensitivity C-reactive protein (hs-CRP). We retrospectively enrolled 77 patients with VTE (distal deep vein thrombosis [DVT], n = 19; proximal DVT, n = 32; and pulmonary thromboembolism [PTE], n = 26) and 34 healthy controls. In the performed analysis of variance, the levels of white blood cell, NLR, and hs-CRP were clearly different among the groups (control, distal and proximal DVT, and PTE) (P < .001). Especially, a significant increase from the control group to the DVT and PTE was observed in the analysis made for NLR. In the performed receiver-operating characteristic curve analysis, area under curve (AUC) = 0.849 and P < .001 were detected for NLR > 1.84. For this value, the sensitivity and specificity were determined as 88.2% and 67.6%, respectively. The NLR is an inexpensive and a readily available marker that may be effective in determining the extent of VTE, and it is useful for risk stratification in patients with VTE.

Present study results demonstrated that high thrombus burden in patients with STEMI was associated with impaired postprocedural epicardial and myocardial perfusion and higher no reflow and distal embolization; and increased RDW values were independent predictors of coronary thrombus burden.

The results of the present study indicate that chronic hypertension is associated with an increased in left atrial volumes, a decrease in left atrial passive emptying function, and an increase systolic pump function. Increased left atrial pump function represents a compensatory mechanism in hypertensive patients with left ventricular hypertrophy.

The TDI method may detect the LAA systolic dysfunctions, which cannot be detected using classical methods, on tissue level in patients with mitral regurgitation. In addition, the deterioration of the LAA functions at tissue level in patients with rheumatic mitral stenosis was also detected.

This study was planned to assess whether tissue Doppler imaging is a useful method for the detection of the right ventricular myocardial infarction. Forty-eight patients with acute inferior myocardial infarction and 24 age- and sex-matched healthy controls were included in this study. Twenty-four patients had electrocardiographic signs of inferior myocardial infarction without right ventricular infarction (group I), and the other 24 patients had electrocardiographic signs of inferior myocardial infarction with right ventricular infarction (group II). From the echocardiographic apical four-chamber view, peak systolic, early diastolic, and late diastolic velocities of the tricuspid annulus at the right ventricular free wall were recorded with the use of pulsed-wave Doppler tissue imaging. The tricuspid annular peak tissue Doppler imaging systolic velocity was significantly lower in group I (14.03 +/- 2.57 cm/s, P << 0.005) and in group II (8.50 +/- 0.84 cm/s, P << 0.005) than in controls (16.63 +/- 2.31 cm/s). The tricuspid annular peak systolic (8.50 +/- 0.84 cm/s vs 16.63 +/- 2.31 cm/s) and peak early diastolic (10.99 +/- 3.28 cm/s vs 19.39 +/- 4.3 cm/s) velocities were significantly lower in group II than in group I, as compared with controls ( P << 0.001). Peak early diastolic velocity of tricuspid annulus (10.99 +/- 3.28 cm/s vs 19.39 +/- 4.3 cm/s) was significantly lower in group I than in controls ( P << 0.001); however, late diastolic velocity was significantly lower in group II (15.98 +/- 5.08 cm/s, P << 0.05) than in group I (18.21 +/- 2.63 cm/s, P << 0.05) and in controls (19.02 +/- 5.29 cm/s). The results of this study indicate that tricuspid annular peak systolic and early diastolic velocities are reduced in patients with right ventricular infarction. The velocity of the tricuspid annulus by tissue Doppler imaging is simple and can be used to distinguish whether patients with inferior myocardial infarction have right ventricular infarction.
