  ventilation perfusion
Oxygenation index, D-dimer, fibrinogen (FG), lung ventilation/perfusion (V/Q) scan and computed tomography pulmonary angiography (CTPA) were observed before anticoagulation and on day 14 after anticoagulation.
      
In these diseases, the pulmonary bloodflow is impaired by a pathologic constriction of blood vessels that may lead to right ventricular overloading as well as serious worsening of gas exchange mainly caused by ventilation/perfusion mismatch.
      
In severe chronic heart failure (CHF) the ventilatory cost of CO2 elimination during exercise (VE/VCO2) is increased, suggesting ventilation/perfusion (V/Q) mismatch.
      
Ventilation perfusion mismatch, due to inadequate perfusion of ventilated lung apices may be the most likely underlying cause of orthostatic dyspnea in patients with OH.
      
Traditional approaches to diagnosis of deep vein thrombosis and pulmonary embolism are primarily based on the results of compression ultrasonography and the ventilation/perfusion lung scan (V/Q).

Aim:To investigate the charateristics of exercises induced BP reaction in related to the extent of the perfusion defect of myocardiaum during radionuclide imazing study. Methods:Myocardium perfusion imaging by 99m MIBI was carried in 204 patients. The SBP or DBP recovery reaction(SBPR or DBPR) was defind as the ratio of SBP or DBP 3 minutes after exercise to the peak SBP or DBP during exercise. The changes in BP during exercise perfusion study was correlated with the occurrence rate of perfusion defect. Results:(1)The SBP or DBP recovery time after exercise was delayed significantly in group perfusion defect;(2)The SBPR in infarction group was longer than that of patients with reversible perfusion defect;(3)The SBPR increases with the increase number of abnormal segments;(4)Multiple factor regression analysis shows SBPR is the strongest factor involved in the abnormalities of perfusion.Conclusion:SBPR was definitly increased in patients with cardiac ischemia or infarction during exercise test. The prolongation of SBPR was correlated with the severity of perfusion defect and the number of hypo perfusion and perfusion defect.
