  Background & Objectives: Acute myocardial infarction (AMI) is one of the most common causes of admissions in industrialized countries and each year a lot of deaths occur due to this disease. AMI is commonly associated with leukocytosis and an elevated neutrophil count. It is not clear whether neutrophilia is a cause or effect of acute myocardial injury and heart failure. Nevertheless, proving such a correlation will have a lot of clinical utilities.

  Methods: From among 146 patients hospitalized by AMI diagnosis in the CCU ward of Shahid Madani hospital, 68 patients (having our inclusion criteria) took part in this cross-sectional and analytical study. The criteria for AMI were clinical symptoms, ECG criteria and paraclinical findings. CBCH₁ was performed for the patients. All the patients were evaluated for presence or absence of congestive heart failure (CHF) in first 4 days of hospitalization. The data were analyzed with SPSS software using t-test and Chi-square.

  Results: Mean neutrophil count was 11291 in patients with evidence of congestive heart failure (CHF) and 8440 in those without it (P =0.01). This difference was statistically significant. Among 23 patients with CHF, 16 had neutrophil counts >8500, but among 45 patients without CHF only 19 cases showed this value (Odds ratio=3.12, P=0.03). Also among 35 patients with neutrophil counts >8500, 24 patients had ejection fraction (EF) of less than 45% and 11 cases had EF>45%(P=0.015).

Conclusion: In this study we found a direct correlation between neutrophilia on admission and the presence of CHF and echocardiographic left ventricular dysfunction in first 4 days of hospitalization. So the patients with high neutrophilia need more invasive treatments to reduce the possibility of CHF.

Background & Objectives: Venous thromboembolism is a common disorder that is difficult to diagnose clinically but carries significant mortality if untreated. Many diagnostic imaging algorithms for the detection of PTE, including ventilation perfusion lung scan, Doppler ultrasonography of lower extremity and pulmonary CT angiography. This study's aim was the comparison of Doppler ultrasonography of lower extremity with perfusion -ventilation lung scan in patients suspected for pulmonary emboli and finding the best approach for diagnosis of the suspected pulmonary emboli.
Methods: One hundred twenty patients of suspected pulmonary embolism referred by internists to Doppler ultrasonography of lower limbs Department of Imam's Khomeini Hospital were studied. The patients were studied within 48 hour post suspected pulmonary emboli and evaluated with V/Q scan and Doppler ultrasonography.
Results: The prevalence of DVT in lower limbs of patients suspected of pulmonary emboli was %37.5. Results of lung scan in patients suspected pulmonary emboli are as below: High probability in %17.5, intermediate probability in %27.5, low probability in %41.5 and normal in %13.5 Results of lung scan in patients suspected  for pulmonary embolism with DVT are as follow: High probability in %24.4, Intermediate probability in %33.3, low probability in %26.7 and normal in %15.6. Mean age in patients with and without DVT Was 52.53 14.13 and 56.22 17.63 year respectively.
Conclusion: Patients suspected for pulmonary emboli with normal lung scan needs more assessment for DVT in lower extremity with Doppler ultrasonography. Normal Doppler ultrasonography of lower extremity doesn't exclude performing lung scan for approving pulmonary emboli. Doppler ultrasonography and lung scan both need evaluating patients suspected for pulmonary embolism.
