چکیده
mean values for Po2 of 58, 60, and 72 mm Hg, respectively, were found for the three groups. When the same patients breathed oxygen via a nasal cannula or face mask at flow rates of 8 to 12 L/min, values were 106, 128, and 160 mm Hg, respectively. In all instances hemoglobin saturation values in excess of 95% were obtained when the patient breathed oxygen. In 15 patients measurements of the oxygen saturation of right atrial blood permitted calculation of the degree of venous admixture. Saturation of mixed venous blood

Blood-gas changes and pulmonary hemodynamics following acute myocardial infarction.
SUMMARY Arterial and mixed venous oxygen tensions were measured in 24 patients following acute myocardial infarction while they were breathing air and 100% oxygen. Total venous admixture and the right-to-left shunt during 100% oxygen breathing were calculated. These data were related to the pulmonary arterial diastolic pressure, the cardiac index, and the central blood volume. Patients with myo...
متن کاملArterial hypoxemia following acute myocardial infarction.
Arterial hypoxemia was common in 53 patients following acute myocardial infarction. It was most marked in patients with evidence of left ventricular failure. Arterial oxygen tension, however, was reduced in many of the patients who were without evidence of failure. An increase in arterial oxygen tension following three deep breaths suggested maldistribution of ventilation. Right-to-left shuntin...
متن کاملAssessment of Periodontal Parameters and Serum Markers in Patients with Acute Myocardial Infarction
Background: Cardiovascular disease is the leading cause of death in developed countries and is a disease that has many contributing factors. Periodontal disease is one of the factors contributing to the progression of the disease. The aim of this study was to investigate the effect of periodontal disease on the incidence of acute myocardial infarction. Methods: In this case-control study, 60 su...
متن کاملMyocardial damage of the entire ventricular region in a patient with acute myocardial infarction
Technetium-99m-pyrophosphate (99mTc-PYP) has been used, in combination with thallium-201, to estimate the site and extent of myocardial infarcts. We report a case of acute myocardial infarction with severe coronary disease in which the distribution of 99mTc-PYP was extensive. A 78-year-old man presented with dyspnea, and a diagnosis of non-ST-segment elevation acute myocar...
متن کاملQT-Dispersion as a potential marker in prognosis of acute myocardial infarction
Introduction: QT dispersion in a 12 lead ECG represents the heterogeneity of ventricular repolarization. The prolongation of QT-interval dispersion increases the risk of coronary heart disease, ventricular arrhythmia, and sudden cardiac death in patients with myocardial infarction. We aimed to investigate the prognostic value of QT-dispersion in patients with acute myocardial infarction. Meth...
متن کاملstudy of platelet parameters in the patients with acute myocardial infarction referred to Ali Shariati Hospital in 2018
Introdution: The rapid and accurate diagnosis of acute myocardial infarction is essential for effective treatment. Recently, troponin has been introduced as a biochemical marker for early diagnosis of acute myocardial infarction. Platelet parameters (P-LCR, MPV, PDW) play a key role in the pathophysiology of acute coronary syndrome. The aim of this study was to evaluate platelet indexes in the ...
